BACKGROUND OF THE INVENTION

This invention relates generally to the field of portable beverage coolers, and more particularly to an improved type adapted for the cooling of a single sealed container, such as a metallic can or small glass or synthetic resinuous bottle.

It is known in the art to use sealed devices containing liquified chemical compositions having very high specific heats to provide a cooling effect similar to that of melting ice. Such structures have been incorporated in sealed form within rigid jackets to surround wine bottles, for example. It is also known to use such materials within rigid portable cold chests of a type most conveniently molded from polystyrene foam. Other devices known in the art include flexible type jackets adapted to be wrapped about a beverage container using tie strings or Velcro closures.

It is often desirable to manually carry a single or small number or individual bottles or cans of soft drink, beer, or other beverage in cooled condition without the use of a larger container, as for example, during an outdoor walk, or while jogging or riding a bicycle. When the container is maintained in suitably cold condition, it is not comfortable to continuously grasp the container for the reason that the hand becomes chilled. The transfer of heat from the hand to the container also deleteriously affects the cooling effect of the jacket.

SUMMARY OF THE INVENTION

Briefly stated, the invention contemplates the provision in a device of the class described of an improved means for mounting the refrigerant-containing jacket upon the container, and for comfortably carrying the same. To this end, the device includes a flexible planar synthetic resinous jacket having sealed pockets for the retention of a coolant in either solid or liquid state. A hollow longitudinally extending pocket is provided between the walls of the jacket for accommodating an elastic strap or band having mutually interconnecting means at the opposite ends thereof which, when interconnected, resiliently contract the jacket upon an enclosed beverage container. The jacket includes a second strap secured at either end to a lower periphery of the jacket, which, in engaged condition, positions the strap under the bottom wall of an enclosed container to prevent relative slipping. At the upper periphery of the jacket are a series of grommets engaged by elongated cords which provide an insulated means for manual engagement of the device and enclosed bottle or container in pendant relation.

DETAILED DESCRIPTION OF THE DISCLOSED EMBODIMENT

In accordance with the invention, the device, generally indicated by reference character 10, comprises a main body element 11 of laminated synthetic resinous material, including a first or outer wall 12 and a second or inner wall 13. The element is bounded along the periphery thereof by an upper edge 14, a lower edge 15, and end edges 16 and 17. Parallel to the upper and lower edges are a pair of longitudinally extending sealed areas 19 defining an upper compartment or pocket 20, a lower compartment or pocket 21, and a belt retaining channel or pocket 22. First and second transversely extending slots 23 and 24 penetrate the outer wall 12 to provide ingress to the pocket 22 which slidably retains an elongated elastic belt 25 having first and second ends 26 and 27 with mutually interconnecting means 28 thereat.

Disposed on the inner surface 30 of the inner wall 13 are the heat sealed terminals 31 and 32 of an elongated plastic strip 33, the terminals 31 and 32 being so spaced that when the main body element 11 is engaged upon a container 34 the strap 33 will be diagonally disposed with respect to a lower wall thereof.

Disposed along the upper edge 14 are a plurality of grommets 35 which penetrate the upper pocket 20 in sealed relation. These are engaged by first and second cords 36 and 37 of suitable length to enable the jacket and enclosed container to be conveniently manually carried without the necessity of the hands of the user contacting the container.

It will be observed that the beverage container can be opened without the necessity of removing the cooler, thereby permitting, in the case of a resealable container for the contents to be consumed over a period of time.

I wish it to be understood that I do not consider the invention limited to the precise details of structure shown and set forth in this specification, for obvious modifications will occur to those skilled in the art to which the invention pertains.
