DESCRIPTION OF VARIOUS EMBODIMENTS

(14) The present teaching will now be described in more detail with reference to exemplary embodiments thereof as shown in the accompanying drawings. While the present teachings are described in conjunction with various embodiments and examples, it is not intended that the present teachings be limited to such embodiments. On the contrary, the present teachings encompass various alternatives, modifications and equivalents, as will be appreciated by those of skill in the art. Those of ordinary skill in the art having access to the teaching herein will recognize additional implementations, modifications, and embodiments, as well as other fields of use, which are within the scope of the present disclosure as described herein.

(15) Reference in the specification to one embodiment or an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the teaching. The appearances of the phrase in one embodiment in various places in the specification are not necessarily all referring to the same embodiment.

(16) It should be understood that the individual steps of the methods of the present teachings can be performed in any order and/or simultaneously as long as the teaching remains operable. Furthermore, it should be understood that the apparatus and methods of the present teachings can include any number or all of the described embodiments as long as the teaching remains operable.

(17) Many industry standard cylindrical disposable cartridges come with a nozzle cover that fits over the nozzle after the use for storage. Such nozzle covers are intended to prevent the viscous construction material from being exposed to air. It is well known that exposing viscous construction material to air will cause solvents in the viscous construction material to evaporate thus reducing the percentage of solvents in the viscous construction material.

(18) Reducing the percentage of solvents in the viscous construction material will increase the viscosity of the viscous construction material. An increase in viscosity increases the resistance to flow of the viscous construction material, thereby making it more difficult to expel the viscous construction material from the nozzle. Increasing viscosity also makes it more difficult to work with the viscous construction material in many construction applications. Eventually, the viscosity of the viscous construction material reaches a level that clogs the nozzle. Even if the nozzle is cleared, the viscous construction material quickly becomes unusable because it cannot be acceptably applied to the work surface.

(19) The time that it takes the viscous construction material to become unusable varies depending on many factors, such as the type of viscous construction material and solvents used in the viscous construction material, the cylindrical tube construction, and the environmental conditions. However, the time that it takes the viscous construction material to become unusable is relatively short and can be a few hours to a few days depending on the various factors. Consequently, the casual user of viscous construction material typically gets only one, or a few, uses out of the standard cylindrical tube. For many applications, this means that a large portion of the viscous construction material in the tube is wasted because a large enough fraction of solvents evaporate before the remaining material is used.

(20) In addition, nozzle covers that come with cylindrical tubes of viscous construction material typically do not provide a good seal. They are notoriously leaky. Consequently, viscous construction materials commonly leak out of the nozzle cover. Since most of the viscous construction materials are sticky materials and sometimes contain toxic materials, this leaking is highly undesirable. Leaked viscous construction materials often destroy clothing and tool bags and leave messy residues in vehicles and workshops that are difficult to clean up. This undesirable leaking can be exacerbated when environmental conditions, such as temperature and pressure, change. For example, leaving a cylinder of viscous construction material in a hot vehicle often exacerbated the leaking and associated damage.

(21) Thus, one significant problem with the industry standard cylindrical disposable cartridges that are widely used today is that, after their first use, they rapidly lose solvents and degrade to the point that they are not usable. For many casual users, the solvent instability results in the product being a single use product where much of the contents of the cylindrical disposable cartridge are discarded.

(22) One aspect of the present teaching is the realization that the nozzle cap provided with many industry standard cylindrical disposable cartridges containing viscous construction materials is not effective in preventing solvent loss after the cartridges are open because most of the solvent loss actually occurs through the moveable member or plunger device that is typically located at the end opposite to the nozzle.

(23) Experiments were performed where the nozzle of the industry standard cylindrical disposable cartridge was cut in a typical manner before use and the moveable member or plunger device was actuated to dispense the product, as a consumer would do. The exterior of the nozzle was then wiped clean and the nozzle cover was placed on the nozzle. The weight loss in the industry standard cylindrical disposable cartridge was then measured after accelerated stability testing at 86 degrees Fahrenheit and at 120 degrees Fahrenheit. The resulting weights were compared to a control sample. All experiments showed significant weight loss due to the loss of solvents from the construction materials. Various experiments also showed that a majority of the solvent loss was through the moveable member or plunger device and not through the nozzle cover.

(24) FIG. 1A illustrates a front-view of one embodiment of a single-body storage container 100 for a standard cylindrical tube of viscous construction material according to the present teaching. In this embodiment, there is a single body 102 that contains the entire standard cylindrical tube of viscous construction material. In some embodiments, the single body 102 is formed from plastic. For example, the single body 102 can be formed of thermoplastic material including at least one of liquid crystalline polymer, polyethylene, polyamide, polycarbonate, polypropylene, polyphenylene sulfide, thermoplastic elastomer, copolyester elastomer, polystyrene, polyvinyl chloride, polytetraflouroethylene, and poly (methyl methacrylate). One skilled in the art will appreciate that numerous types of plastic materials having the desired mechanical and stability properties can also be used. These plastic materials can be embedded with a colorant.

(25) The single body 102 is open at a bottom end 104 to receive a standard cylindrical tube of viscous construction material. In addition, the single body 102 is dimensioned to contain the entire standard tube of viscous construction material so that the standard tube easily fits into the single body 102, while minimizing the volume of open space in the single body 102 that can be occupied by solvents.

(26) The top end 106 of the single body 102 includes a nozzle enclosure 108 that is dimensioned to receive a nozzle of a standard cylindrical tube of viscous construction material. In one embodiment, the nozzle enclosure 108 is formed directly into the top portion of the single body 102. In other embodiments, the nozzle enclosure 108 is removably attached. Removable nozzles can be attached and detached by numerous means such as a screw-type mechanism or one of many types of locking mechanisms.

(27) In some embodiments, an O-ring or gasket 107 is positioned at the top end 106 of the single body 102. This O-ring or gasket 107 seals the nozzle enclosure 108 from the main body 102. Sealing the nozzle enclosure 108 will prevent solvents from escaping into the main body 102. Sealing the nozzle enclosure 108 will also present a minimal volume around the tip of the standard cylindrical tube of viscous construction material, thereby preventing any substantial amount of solvent from escaping through the tip of the cylinder of viscous construction material. Thus, one aspect of the storage container 100 of the present teaching is that it is dimensioned so that the entire standard cylindrical tube of viscous construction material fits completely within the single body 102 when sealed to substantially prevent any caulking or other construction materials from leaking out of the storage container 100.

(28) The storage container 100 also includes a base 110 that seals the bottom end of the single body 102 fully enclosing the standard cylindrical tube of viscous construction material in the single body 102. In some embodiments, the base 110 includes an O-ring or other type of gasket 112 which can be positioned at a top lip to create an air tight seal. Creating an air tight seal around the bottom end 104 of the storage container 100 is important because a large fraction of the solvents escaping from the standard cylindrical tube of viscous construction material escape from the moveable member or plunger device. Thus, one aspect of the storage container 100 of the present teaching is that it is dimensioned to create an air tight seal at the bottom end 104 to substantially prevent any solvents or caulking or other viscous construction materials from leaking out of the storage container 100. In some methods of use, air is injected into the storage container 100 through a valve to create a positive pressure in the storage container 100 that fills the spaces in the storage container 100 thereby preventing solvents from escaping the nozzle of the standard cylindrical tube of viscous construction material.

(29) FIG. 1B illustrates a top-view of the base 110 of the single body 102 described in connection with FIG. 1A. In one embodiment, the base 110 includes a valve 114 that allows a pump to inject air between the single body 102 and the standard cylindrical tube of viscous construction material. The valve 114 can be a one-way valve that lets air into the single body 102, but prevents air from leaving the single body 102. In some embodiments, the valve 114 includes a pressure release that equalizes the pressure in the single body 102 with its environment to assist in removing the base 110. In other embodiments, the single body 102 includes a separate pressure release valve 116. The pump can also be used to evacuate air and solvents between the single body 102 and the standard cylindrical tube of viscous construction material. The valve 114 can also be a one-way valve that allows air to be removed from the single body 102, but prevents air from going into the single body 102.

(30) FIG. 2A illustrates a front-view of one embodiment of a segmented-body storage container 200 for a standard cylindrical tube of viscous construction material according to the present teaching. FIG. 2B illustrates a back-view of one embodiment of a segmented-body storage container 200 for a standard cylindrical tube of viscous construction material 201 according to the present teaching. Referring to both FIGS. 2A and 2B, the segmented-body storage container 200 comprises a two-segment container having an upper segment 202 and a lower segment 204 that are designed to surround the standard cylindrical tube of viscous construction material 201. In some embodiments, the upper segment 202 and the lower segment 204 can include protrusions 206 that assist in gripping the respective segments 202 and 204 so as to assist in assembling the segmented-body storage container 200. The protrusions 206 can be designed to be strong enough so that a tool can be used on them to rotate them to engage and disengage the upper and lower segments 202, 204 if necessary. The upper segment 202 includes the nozzle enclosure 208. As described in connection with FIG. 1, the nozzle enclosure 208 is dimensioned to receive a nozzle of a standard cylindrical tube of viscous construction material 201. The front-view of the segmented-body storage container 200 also shows a coupling mechanism 210 that is described in FIG. 2D. As described in connection with FIGS. 1A and 1B, the segmented-body storage container 200 can be formed of various types of plastic materials. In some embodiments, at least one of the upper and lower segments 202, 204 includes a valve 209 that can be used for at least one of injecting air into the segmented-body storage container 200, evacuating air from the segmented-body storage container 200, and/or equalizing the pressure inside the segmented-body storage container 200 with the environment.

(31) FIG. 2C illustrates an exploded-view of the segmented-body storage container 200 for a standard cylindrical tube of viscous construction material described in connection with FIGS. 2A and 2B. The exploded-view shows the upper segment 202 and the lower segment 204 separated. The nozzle enclosure 208 is shown as being removably attached and separate from the upper segment 202. In the embodiment shown, the nozzle enclosure 208 screws into the upper segment 202. However, it should be understood that the nozzle enclosure 208 can be removably attached to the upper segment 202 by numerous other fastening, attaching, and locking means. Also, in other embodiments, the nozzle enclosure 208 is formed directly into the top of the upper segment 202. In some embodiments, an O-ring or gasket 212 is positioned at the top of the upper segment 202. This O-ring or gasket 212 seals the nozzle enclosure 208 from the upper and lower segments 202, 204 thereby preventing solvents from escaping from the nozzle enclosure 208. The storage container 200 also includes the coupling mechanism 210 that couples the upper and lower segments 202, 204. Numerous types of coupling mechanisms can be used.

(32) FIG. 2D illustrates one embodiment of a coupling mechanism 210 of the segmented-body storage container 200 for a standard cylindrical tube of viscous construction material described in connection with FIG. 2A. The coupling mechanism 210 comprises a pair of vertical key protrusions 214 positioned opposite to each other on the bottom lip 216 of the upper segment 202. The vertical key protrusions 214 are dimensioned to extend into a pair of vertical slots 218 on the top surface 220 of the lower segment 204. The lower segment 204 includes a pair of horizontal slots 222 extending from the vertical slots 218 on the top surface 220 of the lower segment 204 an angular distance. The pair of horizontal slots 222 is positioned proximate to the top surface 220 of the lower segment 204.

(33) During assembly, the vertical key protrusions 214 in the upper segment 202 are positioned into the vertical slots 218 on the top surface 220 of the lower segment 204. When the vertical protrusions 214 in the upper segment 202 reach the horizontal slots 222 in the lower segment 204, the user rotates at least one of the upper and lower segments 202, 204 so that the vertical key protrusions 214 in the upper segment 202 move into the horizontal slots 222 in the lower segment 204, thereby securing the upper segment 202 to the lower segment 204 of the segmented-body storage container 200.

(34) FIG. 2E illustrates another embodiment of a coupling mechanism 230 of the segmented-body storage container 200 for a standard cylindrical tube of viscous construction material described in connection with FIGS. 2A and 2B. The coupling mechanism 230 is a threaded coupling mechanism that comprises a screw mechanism with mating screw threads for the upper segment 202 and the lower segment 204. Screw threads are very well known in the art. Screw threads are helical structures used to convert between rotational and linear movement or force.

(35) The helix of a thread can twist in two possible directions, which is known in the art as handedness. In the embodiment shown in FIG. 2E, the thread is right handed. However, one skilled in the art will appreciate that the threaded coupling mechanism used to attach the upper and lower segments 202, 204 can include left-handed or right-handed threads. The threaded coupling mechanism shown in FIG. 2E includes a right-hand externally threaded upper segment 202 that mates with a right-hand internally threaded lower segment 204. However, one skilled in the art will appreciate that the upper segment 202 can be internally threaded and the lower segment 204 can be externally threaded in other embodiments.

(36) In some embodiments, a gasket 232, such as an O-ring gasket, is positioned in a groove 234 in the internally threaded lower segment 204. The gasket 232 substantially prevents vapors and viscous material from being passed to an outer surface of the storage container.

(37) During assembly, the externally threaded upper segment 202 is threaded into the internally threaded lower segment 204 by hand. In embodiments that include the gasket 232, the externally threaded upper segment 202 is threaded into the internally threaded lower segment 204 until the gasket 232 is sufficiently compressed to form an air-tight seal.

(38) One skilled in the art will appreciate that numerous other coupling means can be used to couple the upper segment 202 to the lower segment 204 when the cylindrical tube of viscous construction material is positioned inside the segmented-body storage container 200.

(39) FIG. 3A illustrates a front-view of another embodiment of a segmented-body storage container 300 for a standard cylindrical tube of viscous construction material according to the present teaching. FIG. 3B illustrates a back-view of one embodiment of a segmented-body storage container 200 for a standard cylindrical tube of viscous construction material according to the present teaching. The embodiment of the segmented-body storage container 300 is similar to the embodiment of the segmented-body storage container 300 that was described in connection with FIGS. 2A-2E except for the nozzle enclosure. Referring to both FIGS. 3A and 3B, the segmented-body storage container 300 comprises a two-segment container having an upper segment 302 and a lower segment 304. In some embodiments, the upper segment 302 and the lower segment 304 can include protrusions 306 that assist in gripping the respective segments 302 and 304 so as to assist in assembling the segmented-body storage container 300. As described in connection with FIGS. 2A and 2B, the protrusions 306 can be designed to be strong enough so that a tool can be used on them to rotate them to engage and disengage the upper and lower segments 302, 304 if necessary.

(40) The upper segment 302 includes the nozzle enclosure 308 that is dimensioned to receive a nozzle 308 of a standard cylindrical tube of viscous construction material. However, the nozzle enclosure 308 in FIG. 3B includes a plug 312 that is dimensioned to fit into the inner diameter of the nozzle 308 of the standard cylindrical tube of viscous construction material. In one embodiment, the plug 312 is removably attached to the nozzle enclosure 308. For example, the plug 312 can screw into the nozzle enclosure 308 so that it can be easily cleaned and/or replaced with a different plug 312 that can be the same or different dimensions to accommodate a different type of tube of viscous construction material.

(41) Also, in one embodiment, the plug 312 is formed in a tapered shape where the diameter of the plug 312 gradually reduced towards the end of the plug 312. Using the plug 312 is advantageous for certain types of viscous construction materials. For example, viscous construction materials that perform polymerization reactions that are initiated by an oxidation-reduction reaction (sometimes called a redox reaction) are particularly sensitive to exposure to oxygen. For these materials, even the nozzle enclosure 208 described in connection with FIGS. 2A-2E can contain too much oxygen for longer term storage.

(42) In one embodiment, the plug 312 is formed of an inert material such as Teflon that does not react or form a bond with the viscous construction materials. Some known apparatus for sealing tubes of viscous construction materials for a bond with the viscous construction materials that makes it difficult and, in some cases, impossible to remove the apparatus without rendering the tube useful.

(43) One unexpected result from experiments performed by the inventor was that long term stability of these viscous construction materials, which, for example, perform polymerization reactions that are initiated by an oxidation-reduction reaction, is that long term stability is improved when the size of the plug is smaller than the inner diameter of the opening in the nozzle of the tube of viscous construction materials so that some viscous construction material is displaced forming an airtight seal.

(44) The front-view of the segmented-body storage container 300 also shows a coupling mechanism 310 that is described in FIG. 3D. As described in connection with FIGS. 1A and 1B, the segmented-body storage container 300 can also be formed of various types of plastic materials. Also, as described in connection with FIGS. 2A and 2B, in some embodiments, at least one of the upper and lower segments 302, 304 includes a valve 309 that can be used for at least one of injecting air into the segmented-body storage container 300, evacuating air from the segmented-body storage container 300, and/or equalizing the pressure inside the segmented-body storage container 300 with the environment.

(45) FIG. 3C illustrates an exploded-view of the segmented-body storage container 300 for a standard cylindrical tube of viscous construction material described in connection with FIGS. 3A and 3B. The exploded-view shows the upper segment 302 and the lower segment 304 separated. The nozzle enclosure 308 that includes the plug 312 is shown as being removably attached and separate from the upper segment 302. In the embodiment shown, the nozzle enclosure 308 screws into the upper segment 302. This allows for easily changing the plug 312 or then entire nozzle closure 308 including the plug 312. It should be understood that the nozzle enclosure 308 can be removably attached to the upper segment 302 by numerous other fastening, attaching, and locking means.

(46) In other embodiments, the nozzle enclosure 308 including the plug 312 is formed directly into the top of the upper segment 302. In some embodiments, an O-ring or gasket 212 is positioned at the top of the upper segment 302. This O-ring or gasket 212 seals the nozzle enclosure 208 from the upper and lower segments 202, 204, thereby preventing solvents from escaping from the nozzle enclosure 308. The storage container 200 also includes the coupling mechanism 310 that couples the upper and lower segments 302, 304. Numerous types of coupling mechanisms can be used.

(47) FIG. 3D illustrates one embodiment of a coupling mechanism 310 of the segmented-body storage container 300 for a standard cylindrical tube of viscous construction material described in connection with FIG. 3A. The coupling mechanism 310 is the same as the coupling mechanism 210 described in connection with FIG. 2D, which comprises a pair of vertical key protrusions 314 positioned opposite to each other on the bottom lip 316 of the upper segment 302. The vertical key protrusions 314 are dimensioned to extend into a pair of vertical slots 318 on the top surface 320 of the lower segment 304. The lower segment 304 includes a pair of horizontal slots 322 extending from the vertical slots 318 on the top surface 320 of the lower segment 304 an angular distance. The pair of horizontal slots 322 is positioned proximate to the top surface 320 of the lower segment 204. The assembly is the same as the assembly described in connection with FIG. 2D.

(48) FIG. 3E illustrates another embodiment of a coupling mechanism 330 of the segmented-body storage container 300 for a standard cylindrical tube of viscous construction material described in connection with FIGS. 2A and 2B. The coupling mechanism 330 is similar to the coupling mechanism described in connection with FIG. 2E that includes a threaded coupling mechanism that comprises a screw mechanism with mating screw threads for the upper segment 302 and the lower segment 304. As described in connection with FIG. 2E, the thread is right handed. However, one skilled in the art will appreciate that the threaded coupling mechanism used to attach the upper and lower segments 302, 304 can include left-handed or right-handed threads. The threaded coupling mechanism shown in FIG. 3E includes a right-hand externally threaded upper segment 302 that mates with a right-hand internally threaded lower segment 304. However, one skilled in the art will appreciate that the upper segment 302 can be internally threaded and the lower segment 304 can be externally threaded in other embodiments.

(49) Also, as described in connection with FIG. 2E, in some embodiments, a gasket 332, such as an O-ring gasket, is positioned in a groove 334 in the internally threaded lower segment 304. The gasket 332 substantially prevents vapors and construction material from being passed to an outer surface of the storage container for viscous construction material. The assembly is the same procedure as described in connection with FIG. 2E.

(50) As with the embodiments described in connection with FIG. 2E, one skilled in the art will appreciate that numerous other coupling means can be used to couple the upper segment 302 to the lower segment 304 when the cylindrical tube of viscous construction material is positioned inside the segmented-body storage container 300.
