DETAILED DESCRIPTION

(7) The FreeZee is a portable freezing or cooling Koozie that allows the user to keep beverages cold in a portable system. The unit can be encased in an outer-shell using any material, preferably an insulating material. Alternatively, the coil also can be kept exposed, with a safety handle used to protect the user. This unique idea will revolutionize the hydration market by adding a new dimension to keeping your beverage cold. The device illustrated in the drawings provides a cooling or freezing effect by way of the coils to ensure a desired cool temperature. The following represent the various reference numbers that are employed in the drawings.

(8) Reference number 1 is a screw cover that is used to compress a compressed gas cylinder 8 as the cover is tightened compressing it into the pin 7 that will puncture the cylinder 8 and allow the compressed gases to enter the coil 2. In FIG. 2, although it is not illustrated, the bottle or can that is to be cooled would be inserted inside of the coil member 2. In FIG. 2, the compressed gas cylinder 8 is shown disposed within the cylinder chamber 4.

(9) Reference number 2 is the coil that when the compressed gas is forced through will freeze the said coil. A double coil construction can also be used where there is an interior coil that freezes a liquid that is injected in a larger outer coil. The coil may also be encased in any outer sleeve. The outer sleeve can have various designs on it to form a cooling element.

(10) Reference number 3 is a compression fitting that allows a compressed gas to come out at a certain psi. Also, optionally it can be used with CO2 to carbonate the liquid.

(11) Reference number 4 describes the cylinder chamber that holds the cylinder 8 and that also can be constructed with a handle that is schematically illustrated at 9 in FIG. 2.

(12) Reference number 5 is a male connection coupling that allows it to be interchanged with the cylinder chamber 4 to be portable or to remove the chamber 4 and use a larger fill system, as shown in FIG. 3. This makes the unit more universal for large retailers as well as a portable unit for home use.

(13) Reference number 6 is the female connection coupling that is used in combination with the male connection coupling 5 to complete the system and make the structure universal.

(14) Reference number 7 is the pin that is used to puncture the cylinder. The screw cover 1 compresses the cylinder against the pin 7 to break a seal of the cylinder and allow gases to be expelled into the coil 2.

(15) Reference number 8 is the cylinder that the compressed gas is stored in. By providing a cylinder and actuation member in the form of a cover 1, this allows the device to be portable and allows the freeze coil to be activated at any time or location.

(16) Reference number 12 illustrates a coupling of the hose with the larger tank 14.

(17) Reference number 13 is the hose that connects the tank 14 with the coupling 12.

(18) Reference number 14 illustrates the larger storage tank.

(19) As indicated before the drawings illustrate a portable freezing or cooling Koozie that allows the user to keep beverages cold in a portable system. Further details of the coil are found in FIG. 4 which illustrates a portion of the coil structure at 2. Also illustrated in FIG. 4 is an outline of a can or bottle that is disposed within the coil as shown at 22 in FIG. 4. FIG. 4 also shows the coil 2 encased in an outer-shell 20 using any material, preferably an insulating material such as a foam material that has insulating properties. The outer foam sleeve is also illustrated as having an outer layer 24 for containing the foam material and that may be constructed so that a design can be provided on its outer surface. The device illustrated in the drawings provides a cooling or freezing effect by way of the coils to ensure a desired cool temperature.

(20) The container 8 may be readily compressed and maybe in a bellows form so that it can release the cooling gas in a progressive manner as the screw cover 1 is turned. The entire cylinder chamber 4 may be readily de-coupled from the coil structure (via couplers 5, 6) so that the container 8 can be replaced in the chamber 4 after the bottle 8 is depleted. The compression fitting 3 controls the pressure level of the fluid entering the coil structure 2. The embodiment shown in FIG. 3 uses an external larger tank 14 that can feed fluid to the coupler 12 and from there into the coil structure 2. This arrangement allows a multitude of devices to be readily re-filled. For this purpose the coupler 12 may include a one way valve that only allows fluid to flow into the coil structure.

(21) FIG. 5 is a further fragmentary view of a construction wherein the coil structure is completely encased within an insulating layer. FIG. 5 shows the coil structure 2 being completely encased by the foam material at 20A and 20B. FIG. 5 also illustrates the can wall at 22 containing the beverage to be cooled. An outer layer 24 is also shown and upon which a design can be made on an outer exposed surface thereof. Although FIG. 5 only shows a fragmentary part of the structure, the entire coil structure is intended to be surrounded by the insulating material (foam rubber or Styrofoam). The result is that the can wall rests against the inner foam 20B while the outer foam material covers all around the coil structure 2.

(22) Having now described a limited number of embodiments of the present invention, it should now be apparent to those skilled in the art that numerous other embodiments and modifications thereof are contemplated as falling within the scope of the present invention, as defined by the appended claims.
