Abstract
Abstract A portable cooler that maintains a desired low temperature for beverages within conventional consumer containers. The cooler is made up of two molded insulating storage container halves, having matching indentations for receiving a number of beverage containers. The halves close over the containers, bringing a previously refrigerated, removable cold pack into contact with the enclosed containers. The beverage containers are thus cooled by direct contact with the cold pack and by direct contact with one another. The joined halves are removably received within a pocket of a fabric carrier that allows the entire unit to be hand-held or carried on the belt of the user.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
150 words
A portable beverage cooler, comprising: a molded storage container formed in two separable halves adapted to be arranged facing inwardly and in abutment with one another for selectively encasing a prescribed number of beverage containers, each storage container half having a number of beverage container receiving indentations for receiving an equal number of beverage containers with opposite ends of the beverage containers located along parallel planes and with adjacent beverage containers physically contacting one another; said molded storage container being formed of a lightweight heat insulative material; a recess formed in at least one of the storage container halves adjoining and in open communication with one end of the indentations therein; and cold pack means removably received within the recess and selectively removable to be frozen, then subsequently reinserted within the recess to physically engage beverage containers within the indentations for cooling the contents of the beverage containers by conduction.
Claim 2
Dependent Claim
150 words
A portable beverage cooler, comprising: a molded storage container formed in two separable halves adapted to be arranged facing inwardly and in abutment with one another for selectively encasing a prescribed number of beverage containers, each storage container half having a number of beverage container receiving indentations for receiving an equal number of beverage containers with opposite ends of the beverage containers located along parallel planes and with adjacent beverage containers physically contacting one another; said molded storage container being formed of a lightweight heat insulative material; a recess formed in at least one of the storage container halves adjoining and in open communication with one end of the indentations therein; and cold pack means removably received within the recess and selectively removable to be frozen, then subsequently reinserted within the recess to physically engage beverage containers within the indentations for cooling the contents of the beverage containers by conduction.
Claim 3
Dependent Claim
24 words
The cooler as defined by claim 1 further comprising: a fabric carrier having a pocket formed therein for removably receiving the molded storage container.
Claim 4
Dependent Claim
33 words
The cooler as defined by claim 2 wherein the fabric carrier includes strap means thereon for enabling selective attachment of the carrier and enclosed molded storage container to a user on his clothing.
Claim 5
Dependent Claim
31 words
The cooler as defined by claim 1 wherein the indentations are concave and spaced apart on parallel axes so adjacent beverage containers received within the indentations will contact one another tangentially.
Claim 6
Dependent Claim
69 words
The cooler as defined by claim 1 wherein there are two recesses and two cold pack means, with one recess situated adjacent one side of the indentations for holding one of the cold pack means against a number of beverage containers, and with the remaining recess being situated adjacent an opposite side of the indentations for holding the remaining cold pack means against an equal number of beverage containers.
Claim 7
Dependent Claim
36 words
The cooler as defined by claim 1 wherein the indentations are semi-cylindrical, formed on parallel, equally spaced axes and wherein the storage container halves are joined along surfaces that lie along planes including the indentation axes.
Claim 8
Dependent Claim
50 words
The cooler as defined by claim 1 for cylindrical cans having equal outside diameters, wherein said cold pack means is comprised of a rectangular vessel containing a refrigerant having a width dimension equal to the diameter of the cans and a length dimension equal to a multiple of can diameters.
Claim 9
Dependent Claim
32 words
The cooler as defined by claim 1 wherein said cold pack means is comprised of a hollow oblong case containing a refrigerant and having a length dimension spanning several of said indentations.
Claim 10
Dependent Claim
55 words
The cooler as defined by claim 1 wherein said storage container is rectangular and removably received within a pocket of a fabric carrier, said carrier having a zippered closure for allowing access to the container and belt loops at an end thereof adapted to be threaded over a belt at the waist of a user.
Claim 11
Dependent Claim
55 words
The cooler as defined by claim 2 wherein the fabric carrier includes a zipper closure at one end of said pocket and an elastic strap extending about the fabric carrier from one end of the zipper closure to an opposite end, allowing the fabric carrier to receive and securely hold the storage container halves together.
