(12) FIG. 11 shows a second embodiment of the present invention. In FIG. 11, the humidification liquid chamber is filled with hydrated reacting chemical compounds that reaction released humidification liquid by their endothermic reactions with one another. The plastic heat-shrinking vapor absorber is between the compartment forming sleeve member bottom wall and the covering sleeve member bottom wall. When the dry gas seal is broken by finger pressure, the covering sleeve member side wall can be massaged by hand to cause the reacting chemical compounds to mix and react endothermically and generate a first endothermic cooling and at the same time create humidification liquid. The humidification liquid vapor is absorbed by dry gas and as before and transported into the plastic heat-shrinking vapor absorber D to cause a second cooling.

A finger is shown pushing on the dry gas seal to deform it and permit humidification liquid to enter into the dry gas chamber in a similar manner to that shown in FIG. 15. The flow of humidification liquid from the humidification liquid chamber is due to the difference in pressure between the dry gas chamber and the humidification liquid chamber. As the plastic heat-shrinking vapor absorber heats up and deforms the annular plastic heat-shrinking vapor absorber retention space it generates a negative pressure in the dry gas chamber. This pulls the humidification liquid from the humidification liquid chamber to the dry gas chamber to saturate the dry gas chamber and cause both endothermic cooling and evaporative cooling.

The dry gas seal 123 cross-sectional dimensions preferably is less than 4 mm. The dry gas seal 123 is preferably expandable to form a tight seal around the food product container 20. The dry gas seal 123 is placed in a plane circumferentially slanted at a small angle relative to the diametric plane of the food product container 20. Since a round-sectioned seal will crawl and tend to symmetrize on the diametric plane of the food product container 20, a rectanguloid-sectioned seal is preferred but not necessary. The dry gas seal 123 is slanted at an angle relative to the relative to the diametric plane of the food product container 20 with a maximal distal separation of about 20 mm below covering sleeve member seal 121. The maximal separation between the covering sleeve member seal 121 and the dry gas seal 123 is dictated by the volume of space that can be formed between the two seals when the apparatus is completed as will be determined later. Seal breaking structure 122 is located between dry gas seal 123 and the covering sleeve member seal 121 before the apparatus 10 is used and should be almost tangent to the dry gas seal 123.

(32) A compartment forming sleeve member 102 is provided with a compartment forming sleeve member side wall 105 and compartment forming sleeve member bottom wall 106 and in a first embodiment, the compartment forming sleeve member 102 is preferably made from impermeable materials such as one of heat-shrinkable stretch-formed polyvinyl chloride (PVC), and heat-shrinkable stretch-formed polyethylene terephthalate (PET), injection molded plastics and rubbers. Other materials may be used depending on the way the compartment forming sleeve member 102 is fashioned. Outward facing surface of the compartment forming sleeve member side wall 105 is preferably lined with a flexible wick 140 made from a wicking material such as one of cotton, porous plastic, woven mesh, absorptive paper, and wool. Compartment forming sleeve member side wall 105 may be laminated with wick 140 on the inside surfaces also. Wick 140 must be thin to reduce its impact as a thermal mass on the functioning of the apparatus 10. Compartment forming sleeve member 102 can initially be formed with cylindrical compartment forming sleeve member side wall 105 and then lined with the wick 140 and then molded into a variety of shapes by one of compressive molding and heat-shrinking to form projected protuberances on its surface. Otherwise its shape may be injection molded with the wick 140 placed inside the mold side walls to adhere to the compartment forming sleeve member side wall 105. For example, compartment forming sleeve member side wall 105 is preferably made with inward facing protuberances 103 and outward facing protuberances 104 respectively on its walls to increase its surface area and provide for strength, surface area, and permit a variety of distinct chemical compounds to be stored between any of the spaces between the protuberances, as shown in FIG. 2, FIG. 12, FIG. 13, and FIG. 20. The number of protuberances must be more than one and can be any suitable number that permits granular chemicals to be stored between said protuberances. FIG. 2, FIG. 12, FIG. 20, FIG. 21 and FIG. 22 are but examples of the possible protuberances that can be made on the compartment forming sleeve member 102. For example, compartment forming sleeve member 102 may be injection molded to have curved or linear ribs projecting as shown in FIG. 22 from its walls to serve the same the same purpose of distinct compartmentalizing the compartment forming sleeve member side wall 105 to store reactive chemical compounds RCC of a variety of chemical compounds S, that can react with one another to provide endothermic cooling, and to store dissolving chemical compounds DCC of a variety of chemical compounds S that can dissolve endothermically in a humidification liquid HL. A variety of projected shapes such as the aforementioned protuberances may be used to increase the strength and surface area of compartment forming sleeve member 102. The projected shapes form channels of such protuberances, such as the inward facing protuberances 103 and outward facing protuberances 104 shown as an example in FIG. 2, FIG. 12, FIG. 20, FIG. 21 and FIG. 22 to give strength to compartment forming sleeve member 102 and also to permit dry gas DG to fill and saturate the outside surface of the compartment forming sleeve member 102 and if required the inside surface the compartment forming sleeve member 102. Preferably the projected protuberances of compartment forming sleeve member 102 form channels along the compartment forming sleeve member side wall 105 to also permit dry gas DG to fill and saturate the compartment forming sleeve member 102. Preferably, the compartment forming sleeve member 102 is lined with a layer of wick 140 to absorb humidification liquid HL and to hold a minimum volume of humidification liquid HL by osmotic pressure without spilling it. Inward facing protuberances 103 and outward facing protuberances 104 of the compartment forming sleeve member side wall 105 must frictionally tangentially contact the food product container side wall 100, to form distinct compartments between the compartment forming sleeve member side wall 105 and the food product container side wall 100.

(33) The compartment forming sleeve member side wall 105 is circumferentially attached to frictionally touch tangentially contact the food product container side wall 100 to cover at least in part the food product container side wall 100 below dry gas seal 123. Ultrasonic welding, glues and tape may also be used to hold it firmly in place and to at least form distinct compartments with the food product container side wall 100. Preferably, the compartment forming sleeve member side wall 105 extends to cover-in-part an exposed surface of the food product container side wall 100 below the dry gas seal 123, but it is anticipated that compartment forming sleeve member side wall 105 may also cover and surround in whole the food product container side wall 100 below the dry gas seal 123, and that compartment forming sleeve member bottom wall 106 extend to cover and surround the food product container domed bottom wall 22 as a cup-like sleeve structure. Inward facing protuberances 103 and outward facing protuberances 104 should be sturdy and prevent compartment forming sleeve member side wall 105 from collapsing under reduced pressures.

(34) Covering sleeve member 30 is provided. Covering sleeve member 30 is preferably made from one of heat-shrinkable materials stretch-formed polyethylene terephthalate (PET), polyvinyl chloride (PVC), and other heat-shrinkable materials also in the form of a thin-walled cup-like structure that to surrounds and encloses in whole or in part the food product container 20. Preferably, covering sleeve member 30 has covering sleeve member side wall 101 shaped to follow the contour of food product container side wall 100. Covering sleeve member side wall 101 can take on a variety of shapes but must permit said covering sleeve member side wall 101 to mate with portions of the food product container side wall 100 during the manufacturing process as will be described in the foregoing. The covering sleeve member side wall 101 covers in whole or in part a sealed food product container 20 containing a food product P. Covering sleeve member side wall 101 is preferably made from one of heat-shrinkable materials stretch-formed polyethylene terephthalate (PET), polyvinyl chloride (PVC), and other heat-shrinkable materials, however, covering sleeve member side wall 101 can also be made with thin aluminum material as a deep-drawn container, and must be re-formable by spin forming and crimping to form seals with the food product container 20. Covering sleeve member side wall 101 preferably covers in-part food product container side wall 100 and may extend to cover in part the food product container top wall 107. The covering sleeve member side wall 101 just slidingly fits over the compartment forming sleeve member 102. Should the covering sleeve member side wall 101 extend and cover the of the food product container top wall 107, then an extension grip 111 made from a simple plastic ring is provided to snap to the food product container top wall seam 114 to permit a user to be able to grip and rotate extension grip 111 and thus rotate the food product container 20 relative to the covering sleeve member 30.

(35) The covering sleeve member side wall 101 covers over compartment forming sleeve member 102 and covers in-whole or in-part the food product container 20. Covering sleeve member side wall 101 preferably covers in-part food product container side wall 100 and may extend to cover in part the food product container top wall 107. Covering sleeve member side wall 101 has a covering sleeve member sealing portion 108 that can be heat-shrunk to shrink in diameter and seal against the food product container side wall 100 to form a covering sleeve member side wall seal 109. As shown in FIG. 17, covering sleeve member side wall 101 may be constructed with support structures 25 such as channels and cavities that permit it to have adequate structural strength to prevent collapse when a rarefication of dry gas GS occurs.

(36) It is anticipated that covering sleeve member side wall end 110 is located at the covering sleeve member sealing portion 108, but it is contemplated that the covering sleeve member side wall end 110 may extend beyond the covering sleeve member sealing portion 108. When the covering sleeve member sealing portion 108 is heat-shrunk or mechanically formed, covering sleeve member side wall 101 clamps around the surface of covering sleeve member seal 121 and dry gas seal 123 to form humidification liquid chamber W between the two seals respectively. Humidification liquid HL is sealingly stored between the humidification liquid chamber w.

(37) The covering sleeve member 30 is rotatable relative to the food product container side wall 100. Thus, advantageously, dry gas seal 123 and covering sleeve member seal 121 rotate with covering sleeve member 30 in unison, relative to the food product container side wall 100. It is anticipated that covering sleeve member side wall 101 deforms by compressive shrinking around the covering sleeve member seal 121 to securely hold the covering sleeve member seal 121 and provide for the same to sealingly rotate with covering sleeve member 30. It is anticipated that covering sleeve member side wall 101 partially deforms by compressive shrinking around the covering sleeve member seal 121 to securely hold the covering sleeve member seal 121 and provide for the same to sealing rotate with covering sleeve member 30. However, it is anticipated that covering sleeve member seal 121 may not rotate with covering sleeve member 30 but still forms a seal. However, dry gas seal 123 must rotate in unison with covering sleeve member 30 relative to the food product container side wall 100.

(38) Covering sleeve member side wall 101 has a covering sleeve member sealing portion 109 that can be heat shrunk or mechanically formed to shrink and seal against the food product container side wall 100 as stated above. Covering sleeve member side wall 101 when shrunk also seals against the dry gas seal 123, pressing the same against the food product container side wall 100 to form a seal. It is anticipated that covering sleeve member sealing portion 108 deforms partially around the covering sleeve member seal 121 to securely hold the covering sleeve member seal 121 and provide for the same to rotate with covering sleeve member 30. It is anticipated that covering sleeve member side wall 101 also partially deforms around the dry gas seal 123 to securely hold the dry gas seal 123 and provide for the same to sealingly rotate with covering sleeve member 30 when rotated. This provides a first cooling actuation means , when covering sleeve member 30 is rotated.

(39) Covering sleeve member side wall 101 has a covering sleeve member restriction portion 128 that can one of be heat-shrunk and be mechanically formed to clamp against a portion of the compartment forming sleeve member 102 to form a restricted vapor passageway 129a for humidification liquid HL vapor Vw and dry gas DG to pass through in a controlled manner. It is anticipated that when the covering sleeve member restriction portion 128 is shrunk, it clamps firmly around the surface of compartment forming sleeve member 102 and closes off any protuberances or projections to form a rotatable restricted vapor passageway 129a. It is anticipated that covering sleeve member side wall 101 slidingly rotates over restricted vapor passageway 129a when rotated.

(40) Covering sleeve member 30 has covering sleeve member bottom wall 130 that sealing connects to covering sleeve member side wall 101. Covering sleeve member bottom wall 130 sealing connects to an inward protruding covering sleeve member shrinkable annular wall 133. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding.

(41) Covering sleeve member inner surfaces define in part the dry gas chamber DGS which extends to cover the compartment forming sleeve member and the space formed by the covering sleeve member bottom wall 130, covering sleeve member shrinkable annular wall 133.

(42) It is anticipated that covering sleeve member 101 may also be made from one of spun aluminum, hydraulically formed aluminum and deep drawn aluminum to provide for all the sealing required. In such a case, covering sleeve member shrinkable annular wall 133 may also be made from one of heat-shrinkable PET and PVC material and added on to the covering sleeve member bottom wall 130 by ultrasonic welding or gluing. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding.

(43) As shown in the figures, a thin-walled open ended support cylinder 132, with support cylinder holes 137 close to its top end may be placed to rest on the covering sleeve member bottom wall 130 between the covering sleeve member side wall 101 and the covering sleeve member shrinkable annular wall 133 and to act as a support member for the covering sleeve member bottom wall 130 against the food product container 20 to prevent shrinking forces from collapsing covering sleeve member bottom wall 130. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding.

(44) Annular plastic heat-shrinking vapor absorber retention space 131 within the dry gas chamber DGS is formed between the space defined by the inner surface of the support cylinder 132, inner surface covering sleeve member shrinkable annular wall 133 and the inner surface covering sleeve member bottom wall 130. Annular plastic heat-shrinking vapor absorber retention space 131 is in fluid communication with the dry gas and is within dry gas chamber DGS. An annular thermal wax retention space 136 is also formed in the dry gas chamber DGS between the outer surface of the support cylinder 132, the inner surface of the covering sleeve member shrinkable annular wall 133 and the inner surface of the covering sleeve member bottom wall 130. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding. Annular thermal wax retention space 136 may be optionally filled with a suitable thermal wax 138 that can melt at temperatures ranging from 70 F. to 160 F. to regulate the amount of heat exposed to the covering sleeve member shrinkable annular wall 133. Support cylinder 132 prevents the covering sleeve member bottom wall 130 from collapsing and deforming its shape relative to food product container 20.

(45) A cooling actuation means is provided when covering sleeve member 30 is rotated with the dry gas seal 123 and dry gas seal 123 crosses over seal breaking structure 122 to break the seal formed by the dry gas seal between the food product container side wall 100 and the covering sleeve member side wall 101 and to expose humidification liquid HL from the humidification liquid chamber W into the dry gas chamber.

(46) The compartment forming sleeve member 102, is preferably designed with inward facing protuberances 103 and outward facing protuberances 104 such as shown in FIG. 2, FIG. 12, FIG. 13, and FIG. 20 to form a pattern of distinct compartments surrounding the food product container side wall 100. In such a case, the inward facing protuberances 103 will be tangent to the food product container side wall 100 and the outward facing protuberances 104 will be tangent to the covering sleeve member side wall 101. This increases its strength and surface area, and permits a variety of distinct reacting chemical compounds RCC that react endothermically and dissolving chemical compounds DCC that dissolve endothermically to be stored isolated from one another in the respective chambers formed between protuberances as shown in FIG. 22. It is anticipated that each respective undulation serves as a storage means for a distinct chemical compounds S that dissolves endothermically to cool.

(47) Annular plastic heat-shrinking vapor absorber retention space 131 holds a plastic heat-shrinking vapor absorber D, such as silica gel, molecular sieves, clay desiccants such as montmorillonite clays, calcium oxide, and calcium sulfide. Annular plastic heat-shrinking vapor absorber retention space 131 is preferably stretch-formed by one of thermoforming, injection-stretch-blowing, and by vacuum forming when covering sleeve member 30 is formed. Covering sleeve member shrinkable annular wall 133 responds to an increase in its temperature by deforming to increase the volume of the dry gas chamber DGS and thus rarefy the dry gas contained therein. This deformation is caused by the plastic heat-shrinking vapor absorber D heating up and thus heating covering sleeve member shrinkable annular wall 133 as it absorbs humidification liquid HL vapor from humidified dry gas DG in the dry gas chamber DGS. The dry gas chamber DGS is in fluid communication with the plastic heat-shrinking vapor absorber D and with the restricted vapor passageway 129a and thus, advantageously, the annular plastic heat-shrinking vapor absorber retention space 131 is in fluid communication with the dry gas chamber DGS, and the interior of the compartment forming sleeve member 102. When the cooling actuation means is activated, the plastic heat-shrinking vapor absorber D heats up the covering sleeve member shrinkable annular wall 133. The covering sleeve member shrinkable annular wall 133 protrudes and intrudes into the dry gas chamber DGS. The shape of the protuberance is important in enhancing the cooling performance of the apparatus. The shape of the protuberance formed by covering sleeve member shrinkable annular wall 133 can be an inverted cup, a dome, and preferably any suitable shape that minimizes the volume of dry gas chamber DGS. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding.

(48) The shape of covering sleeve member shrinkable annular wall 133 must minimize the dry gas chamber DGS and maximizes its intrusion into the dry gas chamber DGS. In the examples shown in the figures, the shape of the of the protuberance formed by covering sleeve member shrinkable annular wall 133 is an inverted cup-like shape and a dome. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding. When heated, the to covering sleeve member shrinkable annular wall 133 shrinks and minimizes its area. The annular plastic heat-shrinking vapor absorber retention space 131 expands and increases in volume outwardly and causes the volume of the dry gas chamber DGS to maximize and generate a substantially lower pressure on dry gas DG that is less than its initial pressure which preferably is just below atmospheric ambient pressure. This lowers the vapor pressure of the dry gas DG and any humidification liquid vapor Vw in the dry gas chamber DGS.

(49) The compartment forming sleeve member 102 is preferably made from an impervious plastic material such as PET and PVC. However, in a fifth embodiment of the invention, said compartment forming sleeve member 102 may be made from a simple corrugated cardboard. If made from a non-plastic material, the protuberances of the compartment forming sleeve member 102 can also be formed by means non-water soluble glues added to a wicking material to form compartment forming sleeve member 102 and then molding the material to the desired shape as the glue dries. It is anticipated that compartment forming sleeve member 102 can be made to have outward facing protuberances 104 that can just hold humidification liquid HL against the food product container side wall 100 when it receives, and also hold chemical compounds S against the food product container side wall 100.

(50) To form the inward facing protuberances 103 and the outward facing protuberances 104, the material used to make compartment forming sleeve member 102 is placed over a mold and formed by one of heat-shrinking, if made from heat-shrinkable material, injection molded, if made from a plastic material, and press formed with glue, if made from a wicking material. Thus, the compartment forming sleeve member 102 can have inward facing protuberances 103 and the outward facing protuberances 104 which when bounded by the food product container side wall 100 can hold not only liquids but also distinct chemical compounds S that can one of, dissolve endothermically and cool by their solvation and react endothermically and reaction released humidification liquid and cool. It is anticipated that if the to compartment forming sleeve member 102 can also be formed as a moldable wick material such from a cotton with a dryable insoluble glue added to it.

(51) A cardboard 134 is optionally provided but not necessary, to glued to just cover the covering sleeve member bottom wall 130 to act as an insulator and protect the consumer against possible burns from heat generated by the plastic heat-shrinking vapor absorber D. The cardboard 134 must be breathable, and preferably has a small cardboard hole 135 to permit the free flow of gases to and from atmosphere as the annular plastic heat-shrinking vapor absorber retention space wall 133 flattens.

(52) In all the embodiments, it is anticipated that the walls and the interior of the material of compartment forming sleeve member 102 may be infused with ionizable chemical compounds S that have reversible endothermic reactions with humidification liquid HL. This can be done by layering the walls of compartment forming sleeve member 102 with ionizable salts such as potassium chloride, ammonium chloride, and ammonium nitrates and other types of endothermic salts with endothermic ionization potential. If made from heat-shrinkable plastic material such as PET and PVC, the compartment forming sleeve member 102 can be heat-shrunk to form its final shape by hot-spraying it at high impact pressure with a stream of particulates of ionizable chemical compounds S to thermally shrink it and form its shape on a mold and coating it at the same time with the ionizable chemical compounds S. In all cases, the compartment forming sleeve member 102 has a wick on its outward surface that must form, as will be described later, a restricted vapor passageway 129a that only permits humidification liquid vapor Vw to pass through to the plastic heat-shrinking vapor absorber D in the dry gas chamber DGS. This is easily achieved in the case of a plastic film material forming the compartment forming sleeve member 102 by banding a wicking material over the compartment forming sleeve member restriction portion 128.

(53) Other methods of inserting ionizable soluble chemical compounds S such as endothermic salts unto and into the material of compartment forming sleeve member 102 include using a polyvinyl acetate (PVA) layer on the outside wall of the compartment forming sleeve member 102 and then attaching the ionizable chemical compounds S to the PVA layer. Other laminating materials such as humidification liquid hl-soluble glues may be used for this purpose.

(54) A dry gas DG is provided inside the dry gas chamber DGS at preferably just under ambient atmospheric pressure. The dry gas GS is provided by a dry gas source DGS and it fills the spaces between the plastic heat-shrinking vapor absorber D and the compartment forming sleeve member 102 in dry gas chamber e.

Method of Manufacture of First Embodiment

(55) A manufacturing method M of the apparatus 10 is described herein as shown in FIG. 18 and FIG. 19. This manufacturing method M generally applies to all the embodiments except for some ordering of tasks that may either change or be eliminated as required. A standard food product container 20 is provided. A covering sleeve member seal 121 provided and covering sleeve member seal 121 is placed circumferentially and sealingly tight around the food product container side wall 100 in a plane parallel to the diametric plane of the food product container 20 and to band around the food product container top wall seam 114.

(56) A dry gas seal 123 is provided as a rectanguloid seal like a rubber band and is expanded and placed in a plane circumferentially slanted at a small angular slant relative to the diametric plane of the food product container side wall 100 to have a maximal separation of about 50 mm and a minimal separation of about 20 mm below covering sleeve member seal 121. Preferably, a plastic self-adhesive label forming the seal breaking structure 122 is provided and attached to the food product container side wall 100 to lay inside and between the maximal separation gap between dry gas seal 123 and the covering sleeve member seal 121.

(57) A compartment forming sleeve member 102 is provided, and attached circumferentially to cover at least in part the food product container side wall 100 below dry gas seal 123 using with one of friction, a glue and double sided adhesive tape.

(58) Covering sleeve member 30 is provided as cup-like structure with straight covering sleeve member side wall 101 as shown in FIG. 2. Covering sleeve member side wall 101 should be taller than food product container 20 by at least 50 mm and should extend beyond the food product container top wall 107. The covering sleeve member side wall 101 just fits over to cover and surround the compartment forming sleeve member 102.

(59) Support cylinder 132 is placed to sit on covering sleeve member bottom wall 130 with support cylinder holes 137 close to the food product container 20 to form the annular plastic heat-shrinking vapor absorber retention space 131 and the annular thermal wax retention space 136. Thermal wax 138 is placed to fill the annular thermal wax retention space 136 and plastic heat-shrinking vapor absorber D is filled into the annular plastic heat-shrinking vapor absorber retention space 131.

(60) Food product container 20 with the compartment forming sleeve member 102, seal breaking structure 122, the covering sleeve member seal 121 and the dry gas seal 123, is inserted to sit on support cylinder 132 inside the covering sleeve member 30.

(61) A cylindrical rod CR is provided with a through hole TH through its length and with a three-way fitting TFW attached to the through hole TH. The first input of the three-way fitting TFW is connected by a dry gas hose DGH to fluidly communication with dry gas pressure canister DGC via a dry gas valve DGV. The second input of the three-way fitting TFW is connected by a vacuum pump hose VPH to a vacuum pump VP via a vacuum valve Vv. The third input of the three-way fitting TFW is co a humidification liquid valve HLV which is connected by a humidification liquid hose HLH to a humidification liquid valve HLT.

(62) The cylindrical rod CR outer diameter is made to fit exactly inside the covering sleeve member 30 and it is inserted about 20 mm into the open end of covering sleeve member 30 and covering sleeve member 30 is heat shrunk to seal around it. The humidification liquid valve HLV, the dry gas valve DGV and the vacuum valve Vv are shut off.

(63) The dry gas valve DGV at a low pressure of about 1 psig and the vacuum valve Vv are first opened to permit dry gas GS to flood the interior of the covering sleeve member 30 to purge any wet air and gases within the covering sleeve member 30 using the vacuum pump VP. After a few seconds of purging, the dry gas valve DGV is turned off to permit the vacuum pump VP to lightly rarify the dry gas DG remaining in the covering sleeve member 30 to a pressure just below ambient atmospheric pressure. A cut off valve to control the pressure may be provided, but the vacuum pump VP itself can be made to provide the rarefication required.

(64) Hot air HA from a heat source HG such as a heat gun is first directed at the location of the covering sleeve member sealing portion 108 to shrink and clamp around the surface of dry gas seal 123 against the food product container side wall 100, after which the hot air HA is removed. This seals in dry gas GS at a rarefied pressure in the dry gas chamber DGS below the dry gas seal 123.

(65) Then, the dry gas valve DGV and the vacuum valve Vv are shut off and the humidification liquid valve HLV is opened to permit humidification liquid HL to fill the annular space above the dry gas seal 123 between the food product container side wall 100 and the covering sleeve member side wall 101 up to a level just below the covering sleeve member seal 121 and then it is shut off.

(66) Hot air HA from the heat source HG is now directed on the location of the covering sleeve member sealing portion 108 to shrink and clamp the covering seal 121 against the food product container side wall 100 after which the hot air HA is removed. This seals in the humidification liquid HL and forms the humidification liquid chamber W between the dry gas seal 123, the covering seal 121, food product container side wall 100 and the covering sleeve member side wall 101.

(67) Then, the extra material of the covering sleeve member 30 above the food product container top wall seam 114 that is still attached to the cylindrical rod CR is cut off to create the covering sleeve member side wall end 110. Extension grip 111 is snapped to the food product container top wall seam 114 to act as an extension of the food product container 20. The apparatus 10 is now ready for use.

Method of Operation of the Apparatus According to the First Embodiment

(68) It is anticipated that the cooling actuation means is activated before the food product release means 113 is used. However, should the food product release means 113 be actuated before the cooling actuation means , then it is anticipated that the pressure drop of the food product container 20 will cause a relaxation of the food product container side wall 100 and slacken the dry gas seal 123 relative to the food product container side wall 100 and thus the apparatus 10 can be still activated as shown in FIG. 10 by simply applying finger pressure 40 and pressing upon the covering sleeve member side wall 101 in the region of the dry gas seal 123 to deform the dry gas seal 123 and the food product container side wall 100 and permit the humidification liquid HL to leak into the dry gas chamber DGS. The apparatus can also be activated by the massage means provided also in the fifth embodiment to break the dry gas seal 123. In all case humidification liquid HL will fall through between the dry gas seal 123 and the food product container side wall 100 due to a gravitational pressure difference, and thus activate the cooling. Thus a second cooling actuation means is provided when food product release means 113 is first used. When cooling actuation means is actuated, the rotation of the covering sleeve member 30 with the covering sleeve member seal 121 and the dry gas seal 123 relative to the food product container side wall 100 causes seal breaking structure 122 to cross under the dry gas seal 123 and break the seal with the food product container side wall 100 that holds humidification liquid HL in the humidification liquid chamber W. Humidification liquid HL enters between the outward facing protuberances in the and dissolves the ionizable chemical compounds S held in them. This causes a first endothermic cooling of the humidification liquid HL. The humidification liquid HL also saturates compartment forming sleeve member side wall 105 and the wick 140 absorbs the humidification liquid as shown in FIG. 10. The dry gas DG absorbs humidification liquid vapor Vw from the wick 140 and the evaporation of the same causes a second further cooling of the humidification liquid HL. Further, a third cooling is achieved when the solution formed by the species of the dissolving chemical compounds DCC of the chemical compound S, and the humidification liquid is dried out by evaporation of the humidification liquid HL into the dry gas GS.

(69) The heat of evaporation H is taken away by the dry gas DG as it becomes wet and lowers its dew point temperature. Note that the dry gas DG temperature does not increase by this process since its dew point temperature takes the heat of evaporation h of the humidification liquid HL away. The higher dew point temperature dry gas DG saturates the dry gas chamber DGS, and enters the restricted vapor passageway 129a. Dry gas DG is an electromotive transport means. The removal of polar water molecules in vapor form into dry gas DG is due to an electromotive heat transport potential. Dry gas DG changes the reactivity of the restricted vapor passageway 129a, (Respir. Physiol. 1997 July; 109 (1):65-72). Negative ions in a dry gas DG attract polar molecules of the humidification liquid HL in the restricted vapor passageway 129a. This is why when air is dry, one gets a greater propensity for electrostatic effects.

(70) The plastic heat-shrinking vapor absorber D may be one of, a liquid, gel, and a solid that absorbs humidification liquid HL vapor Vw. Humidification liquid HL may also be a pressurized liquid in equilibrium with its vapor such as an ammonium solution, a dimethylether solution, and a carbonated solution. In such a case, table 1 provides for the various combinations of the plastic heat-shrinking vapor absorber D, the dry gas GS, and the humidification liquid HL that may be used with the invention.

(71) As dry gas GS wetted by humidification liquid vapor Vw enters through the restricted vapor passageway 129a and then through the support cylinder holes 137 to be absorbed into the plastic heat-shrinking vapor absorber D to dehumidify, its vapor pressure lowers and the dew point temperature of the dehumidified dry gas GS falls far below the dew point temperature of the humidified dry gas DG in the dry gas chamber DGS. Dehumidified dry gas DG in the dry gas chamber DGS is again pulled in by the higher vapor pressure of the dry gas chamber DGS and to again absorb more vapor and transport it to the plastic heat-shrinking vapor absorber D. Plastic heat-shrinking vapor absorber D heats up as it sorbs the humidification liquid vapor Vw and the annular plastic heat-shrinking vapor absorber retention space wall 133 which is tensioned by being pre-stretch-formed, responds to the increase in its temperature by deforming and shrinking in area. When heated, the annular plastic heat-shrinking vapor absorber retention space wall 133 shrinks in surface area and moves outwardly from the food product container domed bottom 22 causing the volume of the dry gas chamber DGS to increase and thus generate a substantial lower vapor pressure in the fixed amount of rarified dry gas DG in the dry gas chamber DGS. This lowers the vapor pressure of the dry gas DG in the dry gas chamber DGS even more and any humidification liquid vapor Vw in the dry gas chamber DGS is pulled into the dry gas DG to evaporate. This deformation of the annular plastic heat-shrinking vapor absorber retention space wall 133 continues with the continued generation of more heat of evaporation h, causing the annular plastic heat-shrinking vapor absorber retention space wall 133 to preferably flatten and thus increase the volume of the dry gas chamber DGS relative to its original volume.

(72) In order to prevent the covering sleeve member bottom wall 130 from collapsing and deforming its shape, support cylinder 132 takes up the compressive forces of the annular plastic heat-shrinking vapor absorber retention space wall 133 against the food product container bottom edge 21 and prevents the covering sleeve member bottom wall 130 from deforming. Thus, the flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133 will not affect the structure of the covering sleeve member bottom wall 130. The deformation and flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133 causes the dry gas chamber DGS to increase in volume, and since there is a fixed amount of dry gas DG in the dry gas chamber DGS, a lower pressure is created inside the dry gas chamber DGS. The annular plastic heat-shrinking vapor absorber retention space 131 is also made larger by the flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133. This causes the plastic heat-shrinking vapor absorber D to continuously shift, move, fall and spread over the flattened annular plastic heat-shrinking vapor absorber retention space wall 133. This spreading agitates the plastic heat-shrinking vapor absorber D and makes it more effective as it assumes a greater surface area. Further, preferably the dry gas DG is preferably at atmospheric pressure when it is stored between the dry gas chamber DGS. The negative pressure generated on the dry gas DG causes even more absorption of humidification liquid vapor Vw into the dry gas DG by evaporation of humidification liquid HL. The approximately 1840-fold expansion of humidification liquid HL into humidification liquid vapor Vw in the dry gas chamber DGS due to the gasification of humidification liquid HL increases the relative vapor pressure of the dry gas chamber DGS in relation to the annular plastic heat-shrinking vapor absorber retention space 131. Thus, advantageously, the humidification liquid vapor Vw in the dry gas chamber DGS naturally wants to enter into the plastic heat-shrinking vapor absorber D. Thus, dry gas DG is an electromotive heat transport means for humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D without the need for a true vacuum.

(73) As dry gas DG delivers the humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D, its actual temperature increases due to the heat generated by the plastic heat-shrinking vapor absorber D. The heat from the plastic heat-shrinking vapor absorber D is partially absorbed by the dry gas DG and its dew point temperature lowers even more. This causes dry gas DG to migrate again into the plastic heat-shrinking vapor absorber D and collect more humidification liquid vapor Vw from dry gas chamber DGS. The cooling continues in this fashion dehydrating the ionizable compounds on the dry gas chamber DGS. The ionizable compounds are not absolutely necessary for the invention to work, however they improve the cooling efficiency since dry gas DG will absorb humidification liquid vapor Vw from even cold humidification liquid HL. The ultimate source of heat of evaporation h is the food product P, which cools by this method. salting the dry gas chamber DGS by drying out the chemical compounds S back to their original form (if used), makes them reusable for further cooling. Drying out the dry gas DG by the plastic heat-shrinking vapor absorber D makes it also reusable again for further cooling.

(74) Further, the deformation motion of the annular plastic heat-shrinking vapor absorber retention space walls 133 causes the plastic heat-shrinking vapor absorber D to move and spread out to permit unexposed plastic heat-shrinking vapor absorber D to take action and effectuate the sorbing of humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D. It is anticipated that a heat-absorbing thermal wax 138 such as ordinary candle wax may be placed in the annular thermal wax retention space 136 between support cylinder 132 and the covering sleeve member side wall 101 to absorb heat of evaporation h from the plastic heat-shrinking vapor absorber D and store the heat of evaporation h. However, this has been found to be effective only if a large amount of plastic heat-shrinking vapor absorber D, is used for a large food product container 20 in excess of 20 oz in volume.

(75) Further the covering sleeve member 30 can be made from shrinkable material such as TPX formed from a combination of plastic materials called Polymethylpentene and glass beads, the resulting covering sleeve member 30 will be capable of quickly releasing absorbed heat of evaporation h through its structure and radiate the heat of evaporation h quickly to atmosphere. Further, the deformation motion of the annular plastic heat-shrinking vapor absorber retention space walls 133 causes the atmospheric air in it to absorb heat from the plastic heat-shrinking vapor absorber D and remove this heat through the cardboard hole 137 if used, or directly to the atmosphere as the heated air volume beneath the flattening annular plastic heat-shrinking vapor absorber retention space walls 133 is expelled.

(76) Cardboard 134 is provided but not necessary. Preferably, but not necessarily, cardboard 134 is made to fit and cover the covering sleeve member bottom wall 130 and is glued to covering sleeve member bottom wall 130 protect the consumer against possible burns. Cardboard 134 has a small central cardboard hole 135 to permit the free flow of gases to atmosphere due to the flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133.

(77) In all embodiments, it is anticipated that the walls and the material used to form compartment forming sleeve member 102 may be layered with ionizable dissolving chemical compounds DCC, that have reversible endothermic reactions with humidification liquid HL.

(78) A dry gas DG is provided inside the dry gas chamber DGS at preferably just under ambient atmospheric pressure. The dry gas GS is provided by a dry gas source DGS and it fills dry gas chamber DGS and the empty spaces between the plastic heat-shrinking vapor absorber D and the compartment forming sleeve member 102.

Second Embodiment of the Invention

(79) Referring to FIG. 11 and FIG. 12, and FIG. 13, a standard food product container 20 is provided. As before, food product container 20 is preferably a cylindrical beverage container of standard design, and with standard food product release means 112.

(80) As shown in FIG. 10 and FIG. 11, and FIG. 12, as before, a covering sleeve member seal 121 is provided in the form of a thin loop structure made from one of an O-ring seal, a metal band seal, a rubber band seal, a putty seal, and sealing wax seal, and a glue bonding agent. Preferably the covering sleeve member seal 121 is provided in the form a looped band, usually O-ring shaped. The covering sleeve member seal 121 cross-sectional dimensions preferably are less than 4 mm. The covering sleeve member seal 121 should form a tight seal around the food product container top wall seam 114. The covering sleeve member seal 121 is placed circumferentially and sealingly tight around the food product container side wall 100 in a plane parallel to the diametric plane of the food product container 20 and close to the food product container top wall 107 to sit around food product container top wall seam 114.

(81) As before, a compartment forming sleeve member 102 is provided as described in the first embodiment, with a compartment forming sleeve member side wall 105 and compartment forming sleeve member bottom wall 106 and as in the first embodiment, the compartment forming sleeve member 102 is preferably made from thin impermeable one of heat-shrinkable stretch-formed polyvinyl chloride (PVC), and heat-shrinkable stretch-formed polyethylene terephthalate (PET). Other materials may be used depending on the way the compartment forming sleeve member 102 is fashioned.

(82) As before, the compartment forming sleeve member 102 can initially be formed with cylindrical compartment forming sleeve member side wall 105 and then molded into a variety of shapes by one of compressive molding and heat-shrinking to form projected protuberances on its surface. Otherwise its shape may be injection molded or compression formed.

(83) As before, compartment forming sleeve member side wall 105 is preferably made with inward facing protuberances 103 and outward facing protuberances 104 respectively on its walls to increase its surface area and provide for strength, surface area, and permit a variety of distinct reacting chemical compounds RCC, to be stored between independent protuberances, as shown in FIG. 13. The number of protuberances must be more than one so that at least reacting chemical compounds RCC may be used with the apparatus 10. A variety of projected shapes of the compartment forming sleeve member side wall 105 such as the aforementioned protuberances may be used to increase the strength and surface area of compartment forming sleeve member 102. The projected shapes form distinct compartments with the protuberances, such as the inward facing protuberances 103 and outward facing protuberances 104 shown as an example in FIG. 11, FIG. 12, and FIG. 13 and FIG. 20, to give strength to compartment forming sleeve member 102, and also to permit reacting chemical compounds RCC to be placed therein and for the dry gas DG to fill and saturate the same. Preferably, the projected protuberances of compartment forming sleeve member 102 form distinct compartments on the compartment forming sleeve member side wall 105 to also permit dry gas DG to interact with the reacting chemical compounds RCC. Inward facing protuberances 103 of the compartment forming sleeve member side wall 105 must frictionally tangentially contact the food product container side wall 100 to form distinct compartments for the reacting chemical compounds RCC between the compartment forming sleeve member side wall 105 and the food product container side wall 100.

(84) The compartment forming sleeve member side wall 105 is circumferentially attached to frictionally tangentially contact the food product container side wall 100 to cover at least in part the food product container side wall 100 below the covering sleeve member seal 121. Grease, soft pliable glues and waxes may also be used to hold it firmly in place and to at least form distinct compartments with the food product container side wall 100. Preferably, the compartment forming sleeve member side wall 105 extends to cover-in-part as much of the exposed surface of the food product container side wall 100 below the covering sleeve member seal 121 as possible.

(85) As before, a dry gas seal 123 is provided preferably also in the form of an O-ring seal, a metal band seal, a rubber band seal, a putty seal, and sealing wax seal, a glue bonding agent and shaped in the form of a thin loop, usually a ring structure. The dry gas seal 123 is placed circumferentially and sealingly tight around the compartment forming sleeve member side wall 105 in a plane parallel to the diametric plane of the food product container 20 and close to the compartment forming sleeve member side wall lower edge 24. A maximal distal separation between the covering sleeve member seal 121 and the dry gas seal 123 is optimum for this version of the invention to work. Dry gas seal 123 when placed around the compartment forming sleeve member side wall lower edge 24 should have an outer diameter slightly greater than the outside diameter of the outward facing protuberances 104 of the compartment forming sleeve member 102. This permits a proper seal to be formed by the dry gas seal 123 with the covering sleeve member 30.

(86) As before, it is anticipated that compartment forming sleeve member side wall 105 may also cover and surround in whole the food product container side wall 100 below the dry gas seal 123, and that compartment forming sleeve member bottom wall 106 extend to cover and surround the food product container domed bottom wall 22 as a cup-like sleeve structure.

(87) As before, the inward facing protuberances 103 of the compartment forming sleeve member 102 are held tangentially tight against the food product container side wall 100 preferably by friction. And again, the outward facing protuberances 104 and the food product container side wall 100 form a collection of distinct compartments with the food product container side wall 100. The inward facing protuberances 103 and the covering sleeve member side wall 101 also form a collection of distinct compartments above the dry gas seal 123. The distinct compartments formed by outward facing protuberances 104 and the food product container side wall 100 and are filled with reacting chemical compounds RCC selected from pairs of hydrated chemical compounds S that react endothermically to generate the humidification liquid HL that will be used by the apparatus 10. Each such one of the pair of reacting chemical compounds RCC selected is placed in a neighboring distinct compartment formed by the outward facing protuberances 104 and the food product container side wall 100.

(88) Covering sleeve member 30 is provided. Covering sleeve member 30 is made from one of stretch-formed polyethylene terephthalate (PET), polyvinyl chloride (terephthalate or PVC), and other materials such as deep drawn aluminum, in the form of a thin-walled cup-like sleeve that surrounds and encloses in whole or in part the food product container 20. Preferably, covering sleeve member 30 has a covering sleeve member side wall 101 that can just slidingly fit over compartment forming sleeve member side wall 105, and has a shape that follows the contour of food product container side wall 100. Covering sleeve member side wall 101 can take on a variety of shapes but must permit said covering sleeve member side wall 101 to mate sealingly with portions of the food product container side wall 100 to hold and form seals with the dry gas seal 123 and the covering sleeve member seal 121 when so formed as will be described in the foregoing.

(89) The covering sleeve member side wall 101 covers in whole or in part a sealed food product container 20 containing a food product P with the compartment forming sleeve member 102 attached. Covering sleeve member side wall 101 preferably covers in-part food product container side wall 100 and may extend to cover in part the food product container top wall 107. Covering sleeve member side wall 101 can be made with many types of materials but preferably heat-shrinkable plastics such as PET and PVC are preferred. Covering sleeve member side wall 101 can also be made with aluminum as a deep drawn container, and must be re-formable by spin forming and crimping to form seals with the food product container 20.

(90) As before, covering sleeve member 30 has covering sleeve member bottom wall 130 that sealing connects to covering sleeve member side wall 101. Covering sleeve member bottom wall 130 sealing connects to an inward protruding covering sleeve member shrinkable annular wall 133. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding.

(91) As stated earlier, it is anticipated that covering sleeve member 101 may be made from spun or deep drawn aluminum and formed to provide for all the sealing required by spin forming and rolling it in parts. In such a case, covering sleeve member shrinkable annular wall 133 may be made from heat-shrinkable PET or PVC material and added on to the covering sleeve member bottom wall 130 by ultrasonic welding or gluing. If needed, a thin-walled open ended support cylinder 132, with support cylinder holes 137 close to its top end is placed to rest at the opposite open end on the covering sleeve member bottom wall 130 between the covering sleeve member side wall 101 and the covering sleeve member shrinkable annular wall 133 and to contact the food product container 20. If the covering sleeve member side wall 101 is made strong enough, support cylinder 132 is not necessary.

(92) Also as described earlier, annular plastic heat-shrinking vapor absorber retention space 131 within the covering sleeve member 30 is formed between the space defined by the inner surface of the support cylinder 132, inner surface covering sleeve member shrinkable annular wall 133 and the inner surface covering sleeve member bottom wall 130. Annular plastic heat-shrinking vapor absorber retention space 131 is filled with a plastic heat-shrinking vapor absorber D up to the height of the covering sleeve member shrinkable annular wall 133.

(93) An annular thermal wax retention space 136 is also formed in the covering sleeve member 30 between the outer surface of the support cylinder 132, the inner surface of the covering sleeve member side wall 102 and the inner surface of the covering sleeve member bottom wall 130. Annular thermal wax retention space 136 may be optionally filled up to the height of the support cylinder 132, with a suitable thermal wax 138 that can melt at temperatures ranging from 70 F. to 160 F. Support cylinder 132 prevents the covering sleeve member bottom wall 130 from collapsing and deforming its shape relative to food product container 20.

(94) When covering sleeve member is placed over the food product container 20 and the attached compartment forming sleeve member 102, the compartment forming sleeve member bottom wall 106 rests on the support cylinder 137 and the outward facing protuberances 104 on the compartment forming sleeve member side wall 105 tangentially touch the covering sleeve member side wall 101 to form distinct compartments 105b between the said walls. The covering sleeve member side wall 101 covers over the attached compartment forming sleeve member 102 and covers in-whole or in-part the food product container side wall 100. Inward facing protuberances 103 and the covering sleeve member side wall 101 form a collection of distinct compartments 105b above the dry gas seal 123 as shown in FIG. 13, and FIG. 20. Covering sleeve member side wall 101 preferably covers in-part food product container side wall 100 and may extend to cover in part the food product container top wall 107.

(95) As before, the covering sleeve member side wall 101 just fits over the compartment forming sleeve member 102 and should just tangentially touch the dry gas seal 123 tangentially. As before, the covering sleeve member side wall 101 has a covering sleeve member sealing portion 118 that is then shrunk in diameter to form a seal between the compartment forming sleeve member side wall 105 and the covering sleeve member side wall 101. This seal is used to seal a dry gas GS rarefied to just below atmospheric pressure and thus form a dry gas chamber DGS below the dry gas seal 123 that contains the support cylinder 132, the annular thermal wax retention space 136 with a thermal wax 138 therein, the annular plastic heat-shrinking vapor absorber retention space 131 with the plastic heat-shrinking vapor absorber D contained therein.

(96) Preferably, more reacting chemicals compounds RCC are then placed in the distinct compartments 105b thus formed by the inward facing protuberances 103 and the covering sleeve member side wall 101. These distinct compartments 105b are adjacent to reacting chemicals compounds RCC that have been placed in the distinct compartments 105b formed before by the outward facing M protuberances 104 and the food product container side wall 100. Of course one could use the inward facing protuberances 103 and outward facing protuberances 104 to respectively store separate and different species of reacting chemical compounds RCC selected as pairs. Thus more than one species of pairs of reacting chemical compounds RCC can be used with the apparatus 10. Preferably the variety of distinct reacting chemical compounds RCC that can react with each other endothermically are species chosen from pairs such as BA(OH).sub.2.Math.8H.sub.2O(s) and NH.sub.4SCN(s), and NH.sub.4NO.sub.3(s), and NH.sub.4CL(s). These reacting chemical compounds RCC have humidification liquid HL stored between their hydrated structure.

(97) A humidification liquid chamber w, is thus formed above the dry gas seal 123 with inward facing protuberances 103 and outward facing protuberances 104 containing the reacting chemical compounds RCC that have water as humidification liquid HL in them. To avoid premature reactions, the reacting chemical compounds RCC pairs that can react with one another are placed in distinct outward facing protuberances 104 separated by inward facing protuberances 103 respectively. The same is true for the reacting chemical compounds placed in distinct inward facing protuberances 103 separated by outward facing protuberances 104 respectively.

(98) Dry gas GS rarefied to just below atmospheric pressure is provided to fill and purge covering sleeve member 30 further. Covering sleeve member side wall 101 has a covering sleeve member sealing portion 108 that can be shrunk in diameter to seal over covering seal 121 and form seal form a covering sleeve member side wall seal 109. Covering sleeve member sealing portion 108 when shrunk in diameter forms a seal with the covering seal 121 between the food product container top wall seam 114 and the covering sleeve member 30 to seal off the humidification liquid chamber W from atmosphere.

(99) As before, it is anticipated that covering sleeve member side wall end 110 is located at the covering sleeve member sealing portion 108, but it is contemplated that the covering sleeve member M side wall end 110 may extend beyond the covering sleeve member sealing portion 108.

(100) Covering sleeve member sealing portion 108 can be either be heated and heat shrunk if made from heat-shrinkable material or roll formed roll formed with a rolling former machine to shrink in diameter and seal against the covering seal 121 against the food product container top wall seam 114 and hold the rarefied dry gas GS therein.

(101) FIG. 13 shows the separation arrangement of the reactive chemical compounds RCC in the humidification liquid chamber W.

Method of Manufacture of Second Embodiment

(102) A standard food product container 20 is provided.

(103) As before, a dry gas seal 123 is provided and first placed circumferentially and sealingly around the food product container side wall 100 in a plane parallel to the diametric plane of the food product container 20 and to band and seal around the compartment forming sleeve member side wall bottom edge 24.

(104) As described earlier, the compartment forming sleeve member 102 is provided preferably as a cylindrical structure with inward facing protuberances 103 and outward facing protuberances 104. Inward facing protuberances 103 should have a diameter that is just a slide fit over food product container side wall 100. Thus compartment forming sleeve member 102 is slid over the food product container side wall 100 to sit on dry gas seal 123 and attached circumferentially to cover at least in part the food product container side wall 100 above the dry gas seal 123.

(105) The desired species of reacting chemicals compounds RCC are then filled into the respective outward facing protuberances 104 that form respective chambers.

(106) As before, a covering sleeve member seal 121 is provided and placed circumferentially and tightly around the food product container side wall 100 in a plane parallel to the diametric plane of the food product container 20 and to band around the food product container top wall seam 114.

(107) As before, covering sleeve member 30 is provided. Covering sleeve member side wall 101 should be of a length greater than the food product container 20 and in fact it is preferable that it extends beyond the food product container top wall 107 by at least 50 mm for manufacturing purposes.

(108) To avoid repletion, as before support cylinder 132 (not shown as an example of not being absolutely necessary) may be placed to sit on covering sleeve member bottom wall 130 with support cylinder holes 137 close to the food product container 20 to form the annular plastic heat-shrinking vapor absorber retention space 131 and the annular thermal wax retention space 136. Thermal wax 138 (not shown as an example of not being absolutely necessary) is placed to fill the annular thermal wax retention space 136. Plastic heat-shrinking vapor absorber D is filled into the annular plastic heat-shrinking vapor absorber retention space 131.

(109) The subassembly of the food product container 20, the compartment forming sleeve member 102, the covering sleeve member seal 121 and the dry gas seal 123 just sit frictionally against the covering sleeve member side wall 101 with compartment forming sleeve member bottom wall 106 spaced above plastic heat-shrinking vapor absorber D. The desired species of reacting chemicals compounds RCC are then filled into the respective inward facing protuberances 103 that form respective chambers with the covering sleeve member side wall 101.

(110) Cylindrical rod CR is provided as before. The humidification liquid valve HLV, the dry gas valve DGV and the vacuum valve Vv are shut off.

(111) The dry gas valve DGV at a low pressure of about 1 psig and the vacuum valve Vv are first opened to permit dry gas GS to flood the interior of the covering sleeve member 30 to purge any wet air and gases within the covering sleeve member 30 using the vacuum pump VP. After a few seconds of purging, the dry gas valve DGV is turned off to permit the vacuum pump VP to lightly rarify the dry gas DG remaining in the covering sleeve member 30 to a pressure just below ambient atmospheric pressure. Hot air HA from heat source HG is first directed at the location of the covering sleeve member side wall 118 with covering sleeve member sealing portion 119 to heat-shrink it in diameter to form a seal between the covering sleeve member side wall 100 against the dry gas seal 123 and causes the dry gas seal 123 to seal against the compartment forming sleeve member side wall 105, after which the hot air HA is removed. This traps dry gas GS in a rarefied state in the plastic heat-shrinking vapor absorber D below the dry gas seal 123.

(112) As before, if made from a heat-shrinkable plastic, hot air HA is then directed at the location of the covering sleeve member sealing portion 108 of the covering sleeve member side wall 101 to shrink and clamp the covering sleeve member sealing portion 108 around the surface of covering sleeve member seal 121 to clamp the same against the food product container top wall seam 114 and form a seal, after which the hot air HA is removed. This seals the humidification liquid chamber W with rarefied dry gas GS.

(113) If made from a deep drawn and spun aluminum, forming rollers from a rolling forming machine RFM is directed at the location of the food product covering sleeve member sealing portion 108 of the covering sleeve member side wall 101 to shrink and clamp the covering sleeve member sealing portion 108 around the surface of covering sleeve member seal 121 to form the seal against the food product container top wall seam 114.

(114) Thus dry gas GS at a rarefied pressure is now sealed inside the humidification liquid chamber w, and inside the dry gas chamber DGS and also permeates the plastic heat-shrinking vapor absorber D. Then, the dry gas valve DGV and the vacuum valve Vv are shut off. As before, the extra material of the covering sleeve member 30 that is still attached to the cylindrical rod CR is cut off to create the covering sleeve member side wall end 110. The apparatus 10 is now ready for use.

Method of Operation of the Apparatus According to the Second Embodiment

(115) Cooling actuation means 40 is activated by using finger pressure f to deform the dry gas seal 123 causing fluid communication between the humidification liquid chamber W and the dry gas chamber DGS. It is anticipated that cooling actuation means 40 is activated before the food product release means 113 is used. However, should the food product release means 113 be actuated before the cooling actuation means, then it is anticipated that the pressure drop of the food product container 20 will cause a relaxation of the food product container side wall 100 and slacken the grip of the dry gas seal 123 relative to the compartment forming sleeve member side wall 105 and thus will cause fluid communication between the humidification liquid chamber W the dry gas chamber DGS and the plastic heat-shrinking vapor absorber D.

(116) The covering sleeve member side wall 101 can then be massaged by hand relative to the compartment forming sleeve member side wall 105 to cause the reacting chemical compounds RCC in the humidification liquid chamber W to react with each other to endothermically cool and at the same time reaction released humidification liquid HL. The massaging deforms the inward facing protuberances and the outward facing protuberances 104 of the compartment forming sleeve member 102 to permit the reacting chemical compounds RCC to mix and react with each other to provide a first cooling means of the apparatus 10 by endothermic reaction cooling and at the same time provides a means to reaction released humidification liquid HL for a second cooling means.

(117) The rarefication of the dry gas GS will force humidification liquid HL thus generated by reactions to evaporate as humidification liquid vapor Vw into the dry gas dg. The dry gas DG absorbs humidification liquid vapor Vw and this lowers the dew point temperature of the dry gas DG and it to becomes wet gas in a third cooling means of the apparatus 10. Additional heat of evaporation, h, is taken away from the humidification liquid HL by the dry gas DG as it becomes wet and lowers its dew point temperature. The higher dew point temperature dry gas DG saturates the dry gas chamber DGS and is absorbed by the plastic heat-shrinking vapor absorber D in the annular plastic heat-shrinking vapor absorber retention space 131. Plastic heat-shrinking vapor absorber D heats up as it sorbs the humidification liquid vapor Vw and the annular plastic heat-shrinking vapor absorber retention space wall 133 which is tensioned by being stretch-formed, responds to the increase in its temperature by deforming and shrinking its area.

(118) As before, when heated, the annular plastic heat-shrinking vapor absorber retention space wall 133 shrinks its surface area and moves outwardly away from the food product container domed bottom wall 22 causing the volume of the dry gas chamber DGS and the humidification liquid chamber W to increase and thus generating a substantial lower vapor pressure in the fixed amount of rarified dry gas DG in the dry gas chamber DGS. This lowers the vapor pressure of the dry gas DG in the dry gas chamber DGS. The pressure in the dry gas chamber DGS is now lower and it will absorb more humidification liquid vapor Vw to continue the cooling process.

(119) Further, the deformation motion of the annular plastic heat-shrinking vapor absorber retention space walls 133 causes the plastic heat-shrinking vapor absorber D to move and spread out to permit unexposed plastic heat-shrinking vapor absorber D to take action and effectuate the sorbing of humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D and a second cooling means is provided by the evaporation of the humidification liquid HL generated by the reactions.

Third Embodiment of the Invention

(120) Referring to FIG. 15, a standard food product container 20 is provided. This embodiment is just another version of the first and second embodiment with the same elements. The difference between this third embodiment and the first embodiment is that the dry gas seal 123 is made at the compartment forming sleeve member side wall top edge 105a of the compartment forming sleeve member side wall 105 and the food product container side wall 100.

(121) As before, covering sleeve member seal 121 is provided as described in the first embodiment of the invention, in the form of a thin loop structure made from one of an O-ring seal, a metal ring seal, a rubber band seal, a putty seal, and sealing wax seal, and a glue bonding agent. The covering sleeve member seal 121 should be expandable to form a tight sealing band around the food product container 20. The loop diameter of covering sleeve member seal 121 is placed circumferentially and sealingly tight around the food product container top wall seam 114 in a plane parallel to the diametric plane of the food product container 20.

(122) As before, a dry gas seal 123 is provided as described in the first embodiment of the invention preferably also in the form of an O-ring seal, metal band seal, a rubber band seal, a putty seal, and sealing wax seal, a glue bonding agent and shaped in the form of a thin loop, usually a ring structure. The dry gas seal 123 is placed circumferentially and sealingly tight around the food product container side wall 100 in a plane parallel to the diametric plane of the food product container 20 and spaced about 20 mm from the covering sleeve member seal 121.

(123) As before, compartment forming sleeve member 102 in the shape of a thin cup is provided with the compartment forming sleeve member side wall 105 and the compartment forming sleeve member bottom wall 106. Compartment forming sleeve member 102 is a thin-walled cup-like structure with compartment forming sleeve member side wall 105 and compartment forming sleeve member bottom wall 106 that surrounds in part the food product container side wall 100 forming an annular gap with the food product container side wall 100.

(124) As before, the compartment forming sleeve member 102 is preferably formed from either injection-molded plastic material such as PET and PVC. The compartment forming sleeve member 102 can also be formed as a thin deep drawn aluminum cup. The compartment forming sleeve member 102 can also be injection molded, however it is anticipated that compartment forming sleeve member 102 is made from heat-shrinkable plastic material such as PET and PVC. As such the compartment forming sleeve member 102 should be tall enough to surround the food product container bottom domed wall 22 and for the compartment forming sleeve member side wall 105 to cover most of the food product container side wall 100 with the compartment forming sleeve member top edge 105a just above the dry gas seal 123. The compartment forming sleeve member side wall 105 is shrunk in diameter to and clamp over the dry gas seal 123 to form a fluid seal between the food product container side wall 100. The inward surface of the compartment forming sleeve member side wall 105, the dry gas seal 123, outward surface of the food product container side wall 100, the outward surface of the food product domed bottom wall 22 and the inward surface of the compartment forming sleeve member bottom wall 106 form a humidification liquid chamber W filled with humidification liquid HL to surround the food product container side wall 100 in part and the food product domed bottom wall 22. Humidification liquid fills the humidification liquid chamber W up to just below dry gas seal 123. Thus, when compartment forming sleeve member 102 is either heat shrunk or crimped to seal over the dry gas seal 123, dry gas seal 123 forms a seal between the compartment forming sleeve member side wall 105 and the food product container side wall 100 in part to form the sealed humidification liquid chamber W which contains humidification liquid HL. The humidification liquid HL thus surrounds the food product container bottom domed wall 22 and the food product container side wall 100 in part.

(125) As before a wick 140 is optionally provided but not necessary. Wick 140 is bonded to the outward facing wall of compartment forming sleeve member side wall 105 as described earlier.

(126) As before, the covering sleeve member side wall 101 has a covering sleeve member sealing portion 118 that can be shrunk in diameter to form a restricted vapor passageway 119a on the wick 140 against the compartment forming sleeve member side wall 105. The compression of covering sleeve member sealing portion 118 also causes the dry gas seal 123 to seal between the compartment forming sleeve member side wall 105 and the food product container side wall 100.

(127) As before, when the covering sleeve member sealing portion 108 is shrunk in diameter it forms a covering sleeve member seal 109 with the covering seal 121 and clamps around the food product container top wall seam 114 to form the dry gas chamber DGS. The dry gas chamber DGS extends between the covering sleeve member seal 121, the covering sleeve member side wall 101, the food product container side wall 100 above the dry gas seal 123 in-part, the dry gas seal 123 and the outward facing surface of the compartment forming sleeve member 102. A dry gas DG preferably just under ambient atmospheric pressure is provided inside the dry gas chamber DGS.

(128) As before, covering sleeve member 30 has covering sleeve member bottom wall 130 that sealing connects to covering sleeve member side wall 101. Covering sleeve member bottom wall 130 sealing connects to an inward protruding covering sleeve member shrinkable annular wall 133. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding.

(129) Food product container 20 is preferably a cylindrical beverage container of standard design, with standard food product release means 113 and a standard food product release port 112.

(130) Covering sleeve member 30 is provided. Covering sleeve member 30 as described earlier is preferably made from one of stretch-formed, stretch blown PET and PVC to form a covering sleeve member 30 in the form of a thin-walled cup-like sleeve, but it can also be formed from deep drawn thin walled aluminum. Covering sleeve member 30 has covering sleeve member side wall 101 that surrounds in whole or in part the food product container 20 with compartment forming sleeve member 102 attached to said food product container side wall 100. Covering sleeve member side wall 101 can take on a variety of shapes to give it strength but must permit said covering sleeve member side wall 101 to mate with portions of the food product container side wall 100 as will be described in the foregoing. The covering sleeve member side wall 101 covers in whole or in part a sealed food product container 20 containing a food product P. Covering sleeve member side wall 101 can be made with other plastic materials that can shrink when heat is applied to their surfaces. Covering sleeve member side wall 101 preferably covers in-part food product container side wall 100 and may extend to cover in part the food product container top wall 107. The covering sleeve member side wall 101 just slidingly fits and circumferentially surrounds the wick 140 on the compartment forming sleeve member 102. Covering sleeve member side wall 101 preferably covers in-part food product container side wall 100 and may extend to cover in part the food product container top wall 107. It is anticipated that covering sleeve member side wall end 110 is located at the covering sleeve member sealing portion 108, but it is contemplated that the covering sleeve member side wall end 110 may extend beyond the covering sleeve member sealing portion 108 and above the food product container top wall 107. When the covering sleeve member sealing portion 108 is shrunk, it clamps around the surface of compartment forming sleeve member 102 and forms an annular dry gas chamber DGS defined by the surfaces of the dry gas seal 123, the covering sleeve member seal 121 and the food product container side wall 100 in part and the covering sleeve member side wall in part.

(131) Covering sleeve member 30 protects compartment forming sleeve member 102. When the covering sleeve member side wall 101 is heat shrunk, it should not clamp around the surface of compartment forming sleeve member 102 but must permit humidification liquid vapor Vw to able to pass between the covering sleeve member side wall 101 and the outward facing compartment forming sleeve member side wall 105. It is anticipated that covering sleeve member sealing portion 118 partially deforms around the compartment forming sleeve member 102 to securely hold the same and provide for a restricted vapor passageway 119a.

(132) The outward facing surface of the compartment forming sleeve member side wall 105, the dry gas seal 123, and the inward facing surface in part covering sleeve member 30 form a dry gas chamber DGS. The outward facing surface of the food product container side wall 100, the covering sleeve member seal 121, and the inward facing surface in part food product container side wall 101 form a humidification liquid chamber w.

(133) Covering sleeve member 30 has covering sleeve member bottom wall 130 that sealing connects to covering sleeve member side wall 101. Covering sleeve member bottom wall 130 sealing connects to an inward protruding covering sleeve member shrinkable annular wall 133. Covering sleeve member shrinkable annular wall 133 is flexible and can respond to pressure changes by either collapsing or expanding. Covering sleeve member shrinkable annular wall 133 is filled with plastic heat-shrinking vapor absorber D up to the level of the covering sleeve member shrinkable annular wall 133. The inside surfaces of covering sleeve member 30 below the covering sleeve member seal 121 form a dry gas chamber DGS containing a dry gas GS.

(134) It is anticipated that covering sleeve member 101 may be made from spun or deep drawn aluminum and formed to provide for all the sealing required by spin forming and rolling it in parts. In such a case, covering sleeve member shrinkable annular wall 133 may be made from heat-shrinkable PET or PVC material and added on to the covering sleeve member bottom wall 130 by ultrasonic welding or gluing. If needed, a thin-walled open ended support cylinder 132 provided as before, with support cylinder holes 137 close to its top end is placed to rest at the opposite open end on the covering sleeve member bottom wall 130 between the covering sleeve member side wall 101 and the covering sleeve member shrinkable annular wall 133 and to contact the compartment forming sleeve member bottom wall 105. If the covering sleeve member side wall 101 is made strong enough, support cylinder 132 is not necessary.

(135) Annular plastic heat-shrinking vapor absorber retention space 131 within the dry gas chamber DGS is formed between the space defined by the inner surface of the support cylinder 132, inner surface covering sleeve member shrinkable annular wall 133 and the inner surface covering sleeve member bottom wall 130. Annular plastic heat-shrinking vapor absorber retention space 131 is in fluid communication with the dry gas chamber DGS and is within dry gas chamber DGS. An annular thermal wax retention space 136 is formed in the dry gas chamber DGS between the outer surface of the support cylinder 132, the inner surface of the covering sleeve member side wall 102 and the inner surface of the covering sleeve member bottom wall 130. Annular thermal wax retention space 136 may be optionally filled with a suitable thermal wax 138 that can melt at temperatures ranging from 70 F. to 160 F. Support cylinder 132 prevents the covering sleeve member bottom wall 130 from collapsing and deforming its shape relative to food product container 20.

(136) A cooling actuation means, 40, is provided when a finger f is used to depress covering sleeve member side wall 101 at the location of the dry gas seal 123 to deform the same and expose humidification liquid HL from the humidification liquid chamber W into the dry gas chamber e.

(137) It is anticipated that compartment forming sleeve member 102 may have shapes and forms that can assist in increasing the surface area, to help evaporation in the dry gas chamber DGS. It is anticipated that ionizable chemical compounds S are selected from the species of dissolving chemical compounds DCC that dissolve endothermically may be placed in inward facing protuberances 103 of the compartment forming sleeve member 102 as described earlier. This can be done by infusing the outward facing surface of compartment forming sleeve member 102 with said ionizable dissolving chemical compounds DCC as described earlier. Restricted vapor passageway 119a is formed by the clamping of covering sleeve member sealing portion 118 on wick 140.

(138) Annular plastic heat-shrinking vapor absorber retention space 131 holds a plastic heat-shrinking vapor absorber D, such as silica gel, molecular sieves, clay desiccants such as montmorillonite clays, calcium oxide, and calcium sulfide. Annular plastic heat-shrinking vapor absorber retention space 131 is stretch-formed from a heat-shrinkable material including various forms of heat-shrinkable PET and various forms of heat-shrinkable PVC. Covering sleeve member shrinkable annular wall 133 responds to heat by deforming and shrinking its surface area. Advantageously, covering sleeve member shrinkable annular wall 133 shrinks in surface area and tends to flatten with heat received from the plastic heat-shrinking vapor absorber to increase the volume of the dry gas chamber DGS. This deformation is caused by the plastic heat-shrinking vapor absorber D heating up as it absorbs humidification liquid HL vapor Vw from humidified dry gas DG in the dry gas chamber DGS. The dry gas GS in the dry gas chamber DGS is in fluid communication with the plastic heat-shrinking vapor absorber D and with the restricted vapor passageway 119a and thus, advantageously, the annular plastic heat-shrinking vapor absorber retention space 131 is in fluid communication with the outside walls of compartment forming sleeve member 102.

(139) The shape of covering sleeve member shrinkable annular wall 133 must minimize the dry gas chamber DGS before it is heated, and thus its intrusion into the dry gas chamber DGS must be designed to maximize and increase the volume of the dry gas chamber DGS. In the examples shown in FIG. 1, the shape of the covering sleeve member shrinkable annular wall 133 is an inverted cup. However, it could take on many shapes as shown in the various figures.

(140) When heated, the covering sleeve member shrinkable annular wall 133 shrinks and minimizes its area. The annular plastic heat-shrinking vapor absorber retention space 131 expands and move outwardly and causes the volume of the dry gas chamber DGS to increase to generate a substantially lower pressure on dry gas DG less than its initial pressure which preferably is just below ambient atmospheric pressure. This lowers the vapor pressure of the dry gas DG and any vapor in the dry gas chamber DGS, and thus the vapor pressure in the compartment forming sleeve member 102. Thus, it is anticipated that covering sleeve member side wall 100 may be designed with annular protuberances or lateral protuberances to strengthen it and prevent it from collapsing under the rarefication force generated by the plastic heat-shrinking vapor absorber D. For example, the inward facing protuberances 103 and outward facing protuberances 104 shown in FIG. 2 may suffice to provide all the strength and surface area required to support covering sleeve member side wall 100 from the rarefication pressure force generated by the plastic heat-shrinking vapor absorber D. It is anticipated that the humidification liquid chamber W can be made to just hold enough humidification liquid HL without overflow when it receives it.

(141) As before, the compartment forming sleeve member 102's outward facing surface forms a part of the dry gas chamber DGS. This surface can also be layered with ionizable compounds S when it is heat shrunk to form its shape by hot-spraying it with a stream of particulates of ionizable compounds carried by heated air at high impact pressure as it is thermally shrunk to form its shape on a mold. A dry gas DG at preferably just below atmospheric ambient pressure is provided inside the dry gas chamber DGS and to also fill the dry gas chamber DGS and create a slight pressure difference between the dry gas chamber DGS (lower pressure) and the humidification liquid chamber W.

(142) FIG. 16 shows the apparatus 10 according to the Fourth Embodiment when the cooling means F is actuated.

Method of Manufacture of Third and Fourth Embodiments

(143) This method is essentially the same as the steps required for the first embodiment with slight differences, a standard food product container 20 is provided.

(144) As before, a covering sleeve member seal 121 is provided and covering sleeve member seal 121 is expanded and placed circumferentially and tightly around the food product container side wall 100 in a plane parallel to the diametric plane of the food product container 20 and to band around the food product container top wall seam 114.

(145) As before, dry gas seal 123 is provided and expanded and placed circumferentially and tightly around the food product container top wall 107 about 20 mm or so below covering sleeve member seal 121 in a plane parallel to the diametric plane of the food product container 20 to band around the food product container side wall 100.

(146) Compartment forming sleeve member 102 is provided in the form of a cup-sleeve as described earlier is provided to frictionally encases and fits over food product container side wall 100 and just cover the dry gas seal 123. As before a wick 140 is optionally provided and bonded to the outward facing wall of compartment forming sleeve member side wall 105.

(147) Humidification liquid HL is poured into compartment forming sleeve member 102 to fill the humidification liquid chamber W between the food product container and the compartment forming sleeve member 102 up to just below the dry gas seal 123.

(148) Hot air HA is first directed at the compartment forming sleeve member 102 at location of the dry gas seal 123 to shrink and clamp the compartment forming sleeve member 102 in part around the surface of dry gas seal 123, after which the hot air HA is removed. This seals in humidification liquid HL and forms the sealed humidification liquid chamber w, formed by the annular gap between the food product container and the compartment forming sleeve member 102 up to just below the dry gas seal 123.

(149) As before, covering sleeve member 30 is provided as cup-like structure with straight covering sleeve member side wall 101 as shown in FIG. 2.

(150) As before, covering sleeve member side wall 101 should be taller than food product container 20 and should extend beyond the food product container top wall 107 by at least 50 mm. The covering sleeve member side wall 101 just fits over the compartment forming sleeve member 102:

(151) As before, support cylinder 132 is placed to sit on covering sleeve member bottom wall 130 with support cylinder holes 137 close to the food product container 20 to form the annular plastic heat-shrinking vapor absorber retention space 131 and the annular thermal wax retention space 136. As before, thermal wax 138 is placed to fill the annular thermal wax retention space 136 and holds a plastic heat-shrinking vapor absorber D is filled in the annular plastic heat-shrinking vapor absorber retention space 131.

(152) As before, food product container 20 with the compartment forming sleeve member 102, compartment forming sleeve member 102 attached, the covering sleeve member seal 121 and the dry gas seal 123 is inserted to sit on support cylinder 132 inside the covering sleeve member 30.

(153) As before, cylindrical rod CR is provided with a through hole TH through its length and with a three-way fitting TFW attached to the through hole TH. As before, the first input of the three-way fitting TFW is connected by a dry gas hose DGH to fluidly communication with dry gas pressure canister DGC via a dry gas valve DGV. As before the second input of the three-way fitting TFW is connected by a vacuum pump hose VPH to a vacuum pump VP via a vacuum valve Vv. As before the third input of the three-way fitting TFW is connected by a humidification liquid tank HLT via a humidification liquid valve HLV.

(154) As before the cylindrical rod CR outer diameter is made to fit exactly inside the covering sleeve member 30 and it is inserted about 20 mm into the open end of covering sleeve member 30 and covering sleeve member 30 is heat shrunk to seal around it. The humidification liquid valve HLV, the dry gas valve DGV and the vacuum valve Vv are shut off.

(155) As stated earlier, the dry gas valve DGV regulated at a low pressure of about 1 psig and the vacuum valve Vv are first opened to permit dry gas GS to flood the interior of the covering sleeve member 30 to purge any wet air and gases within the compartment forming sleeve member 102, the dry gas chamber DGS and in the interior of the covering sleeve member 30 using the vacuum pump VP. After a few seconds of purging, the dry gas valve DGV is turned off to permit the vacuum pump VP to lightly rarify the dry gas DG remaining in the covering sleeve member 30 to a pressure just below ambient atmospheric pressure. A cut off valve to control the pressure may be provided, but the vacuum pump VP itself can be made to provide the rarefication required.

(156) Hot air HA from the heat source HS is now directed on the location of the food product covering sleeve member sealing portion 108 of the covering sleeve member side wall 101 to shrink and clamp around the covering seal 121 after which the hot air HA is removed. This seals and forms the dry gas GS in the dry gas chamber DGS.

(157) Then, the extra material of the covering sleeve member 30 that is attached to the cylindrical rod CR is cut off to create the covering sleeve member side wall end 110. The apparatus 10 is now ready for use.

Method of Operation of the Apparatus According to the Third and Fourth Embodiments

(158) It is anticipated that the cooling actuation means 40 is activated by finger f pressure to deform dry gas seal 123 before the food product release means 113 is used. However, should the food product release means 113 be used before the cooling actuation means 40, then, it is anticipated that the pressure drop due to the absence of a seal in the food product P and also within a carbonated food product to container 20 will cause a relaxation of the food product container side wall 100 and thus compromise the integrity of the seal formed by dry gas seal 123 between the compartment forming sleeve member 102 and the covering sleeve member side wall 101 and the slight rarefication of the dry gas GS will cause a pressure difference between the dry gas chamber DGS (lower pressure) and the humidification liquid chamber w. In either case of the cooling actuation means 40, humidification liquid HL will naturally cause the humidification liquid vapor Vw from the humidification liquid chamber W to evaporate into the dry gas chamber DGS. The slight rarefication of the dry gas GS will cause a pressure difference between the dry gas chamber DGS (lower pressure) and the humidification liquid chamber w. In either case of the cooling actuation means 40, humidification liquid vapor Vw will naturally be forced to evaporate and enter into the dry gas chamber DGS by the pressure difference between the dry gas chamber DGS and the humidification liquid chamber W. This starts the cooling process by evaporation of humidification liquid vapor Vw into the dry gas GS. The same happens when the food product release means 113 is used before the cooling actuation means 40. The hold of the dry gas seal 123 on the food product container side wall 100 is weakened when the carbonation pressure is released from the food product P and the slight rarefication of the dry gas GS will cause a pressure difference between the dry gas chamber DGS (lower pressure) and the humidification liquid chamber w. In either case of the cooling actuation means 40, humidification liquid vapor Vw will naturally be forced by to enter into the dry gas chamber DGS. Humidification liquid vapor Vw passes through into the dry gas chamber DGS which has dry gas DG in it. The dry gas chamber DGS is anticipated to contain chemical compounds S within it. This causes further endothermic cooling. Dry gas GS evaporates the humidification liquid HL into humidification liquid vapor Vw and evaporative cooling occurs. The dry gas DG absorbs humidification liquid vapor Vw and this lowers the dew point temperature of the dry gas DG and it becomes wet gas. The heat of evaporation, H, is taken away by the dry gas DG as it becomes wet and lowers its dew point temperature. As before, the plastic heat-shrinking vapor absorber D heats up as it sorbs the humidification liquid vapor Vw and the annular plastic heat-shrinking vapor absorber retention space wall 133 which is tensioned by being stretch-formed, responds to the increase in its temperature by deforming and shrinking its area.

(159) As before, when heated, the annular plastic heat-shrinking vapor absorber retention space wall 133 shrinks its surface area and moves outwardly away from the food product container domed bottom wall 22 causing the volume of the dry gas chamber DGS to increase and thus generating a substantial lower vapor pressure in the fixed amount of rarified dry gas DG in the dry gas chamber DGS. This lowers the vapor pressure of the dry gas DG in the dry gas chamber DGS. The pressure in the dry gas chamber DGS is now lower and thus humidification liquid vapor Vw is pulled into the dry gas chamber DGS at an accelerated rate. This deformation of the annular plastic heat-shrinking vapor absorber retention space wall 133 continues with the continued generation of more heat of evaporation h and causing the annular plastic heat-shrinking vapor absorber retention space wall 133 to tend to flatten and thus increase the volume of the dry gas chamber DGS relative to its original volume. The deformation and flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133 causes the dry gas chamber DGS to increase in volume, and since there is a fixed amount of dry gas DG in the dry gas chamber DGS, a lower pressure is created inside the dry gas chamber DGS. The annular plastic heat-shrinking vapor absorber retention space 131 is also made larger by the flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133. As before, this causes the plastic heat-shrinking vapor absorber D to continuously shift, move, fall, and spread over the flattened annular plastic heat-shrinking vapor absorber retention space wall 133. This spreading agitates the plastic heat-shrinking vapor absorber D and makes it more effective as it assumes a greater surface area. Thus, dry gas DG is an electromotive heat transport means for humidification liquid vapor Vw into the plastic to heat-shrinking vapor absorber D without the need for a vacuum.

(160) The combination of the humidification liquid HL and the plastic heat-shrinking vapor absorber D is summarized in table 1 below:

(162) FIG. 16 shows yet another version of the third embodiment with the dry gas seal 123 positioned about midway on the food product container side wall 100 to make room above the humidification liquid chamber to hold dissolving chemical compounds DCC above the dry gas seal 123. FIG. 16 also shows an outwardly heat-shrinkable projection 141 that forms the bottom wall of the compartment forming sleeve member 102. Heat-shrinkable projection 141 is an example of an outward projecting structure relative to the food product container 20 that increases the volume of the dry gas chamber DGS when heated by plastic heat-shrinking vapor absorber D, while at the same time it decreases the volume of the humidification liquid chamber W. It acts as a pump for the humidification liquid HL to rise and interact with dissolving chemical compounds DCC to provide endothermic cooling by their solvation. At the same time, the dry gas DG will cause the humidification liquid HL to evaporate to humidification liquid vapor Vw and cause even more cooling by evaporation. Thus by regulating the amount of humidification liquid HL pumped into the dissolving chemical compounds DCC and the evaporation rate of the humidification liquid hl, the drying and dissolving of the dissolving chemical compounds DCC can be regulated to provide for a repeated cooling using the same amount of the chemicals to repeat the solvation process and cooling.

Fifth Embodiment of the Present Invention

(163) As before, a food product container 20 is provided with a food product container side wall 100 and a food product container top wall 107 and opening means 112 with food product release means 113. Food product container side wall 100 has the compartment forming sleeve member 102 with a compartment forming sleeve member side wall 105 with inward facing protuberances 103 preferably on the inside surface as shown in FIG. 23 and FIG. 24. The inward facing protuberances 103 can be in the form of waves with inward facing protuberances 103 as before. Only the inward facing protuberances 103 are preferred in this embodiment, however one can still use the outward facing protuberating 104 for gripping. The inward facing protuberances 103 help to increase strength and permit a variety of distinct reacting chemical compounds RCC to be stored in distinct compartments 105b made between said inward facing protuberances 103 on the compartment forming sleeve member side wall 105. The compartment forming sleeve member 102 can be easily made with a single layer corrugated cardboard to form the distinct compartments 105b between said inward facing protuberances 103 and then laminated over with a plastic self-adhesive label to adhere to the food product container side wall 100. The corrugations can be made to mate with the food product container side wall 100 to form the distinct compartments 105b. It is anticipated that the compartment forming sleeve member 102 can be easily made with a rubber material whose elastic properties can advantageously form the distinct compartments 105b. A compartment forming sleeve sealing portion 105a is provided to form a seal with the food product container wall 100 and enclose the inward facing protuberances 103 to form the to humidification liquid chamber W against the food product container side wall 100. The inward facing protuberances 103 of the compartment forming sleeve member side wall 105 form distinct compartments 105b within the humidification liquid chamber W that can hold chemicals therein in distinct compartments 105b. The inward facing protuberances 103 as shown in FIG. 23 and FIG. 24 are but examples of the possible protuberances that can be made on the compartment forming sleeve member side wall 105. As before, the inward facing protuberances 103 contact and mate with the food product container side wall 100 to form the distinct compartments 105b of the humidification liquid chamber W.

(164) Each reacting chemical compound RCC is held exclusively in a distinct compartment 105b. The dissolving chemical compounds can also be added to be stored exclusively in distinct compartment 105b.

(165) The compartment forming sleeve member 102 has a compartment forming sleeve member sealing portion 105a forms a fluid seal surrounding the inward facing protuberances 103 with a food product container side wall 100. When the compartment forming sleeve member sealing portion 105a is sealed against the surface of the food product container side wall 100, the closed space forms the humidification liquid chamber W which holds reacting chemical compounds RCC and dissolving chemical compounds DCC in between the distinct compartments 105b of the humidification liquid chamber W.

(166) A cooling actuation means is provided by massaging the compartment forming sleeve member 102 with finger pressure F against the food product container side wall 100 to deform the inward facing protuberances 103 against the food product container side wall 100 to permit the reacting chemical compounds RCC to mix with each other and react and generate a first endothermic cooling of the food product P. Advantageously, a second endothermic cooling can be achieved if dissolving chemical compounds DCC are provided to mix and dissolve with reaction released humidification liquid HL from their reactions. The invention as stated in the opening paragraphs provided the following advantages: d) A variety of distinct reacting chemical compounds RCC and dissolving chemical compounds DCC can be stored between any of inward facing protuberances 103 when they form distinct compartments 105b against the food product container side wall 100. Many species of distinct reacting chemical compounds RCC can be stored between the inward facing protuberances 103 when they form distinct compartments 105b against a food product container side wall 100. Thus pairs of endothermically reacting chemical compounds RCC of different species of reactants can be stored in said distinct compartments 105b. Further different species of dissolving chemical compounds DCC can also be stored in said distinct compartments 105b. e) Further, humidification liquid HL created by the reacting chemical compounds RCC can be used to endothermically dissolve dissolving chemical compounds DCC to generate even more cooling. f) deforming and either breaking bending the inward facing protuberances 103 by means of the massaging the compartment forming sleeve member 102 causes reacting chemical compounds RCC to react endothermically that are stored between separate distinct compartments 105b before they react can be made to react when the protuberances are deformed or broken to permit said reacting chemical compounds RCC to mix and react.

(167) The compartment forming sleeve member 102 can also be made a cylindrical sleeve that wraps around the food product container side wall 100. In such a case, the compartment forming sleeve member sealing portion 105a is a barrier structure forming two circumferential sealing bands that enclose the humidification liquid chamber around the food product container side wall 100. The compartment forming sleeve member 102 can also be made from a rubbery and elastic material to make it pliable and to soft enough to be massaged by fingers to mix the said chemicals for cooling.

(168) While the invention has been described, disclosed, illustrated and shown in various terms or certain embodiments or modifications which it has assumed in practice, the scope of the invention is not intended to be, nor should it be deemed to be, limited thereby and such other modifications or embodiments as may be suggested by the teachings herein are particularly reserved especially as they fall within the breadth and scope of the claims here appended.
