Abstract
Abstract A cooler is provided for a typical carbonated beverage can, which facilitates cooling of the can and drinking of beverage from the cold can. The cooler includes a container bottom assembly which closely receives the can and a top assembly which fits into the bottom assembly to trap a can therein. About two-thirds of the height of the can lies in the bottom assembly, and the bottom assembly closely surrounds the can, to keep the can cool even when the top is removed and liquid is drunk from the can lying in the bottom assembly. The bottom assembly includes a refrigerant element having a raised middle portion which is received in the concave bottom of a typical pressurized twelve ounce can. The bottom assembly includes a hard cup-shaped shell and a cup-shaped foam liner, the bottom of the liner being closely held in the shell but the top of the liner being spaced from the shell to provide space for an interfitting lip on the top assembly.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
236 words
A beverae cooler which can keep a beverage-filled can of predetermined diameter cool for an extended period of time while facilitating the drinking of a beverage from the still-cold can comprising: a hollow heat insulated container bottom assembly which includes a bottom end and side walls, and having a hollow inside with a can-supporting wall for supporting the bottom of said can; a hollow heat insulated container top assembly which includes a top end, and which includes side walls which closely mate with the side walls of said bottom assembly to form a can-holding container which avoids the passage of air between the outside and inside of the container to thereby avoid convective heating; said bottom assembly formed to closely surround said can along most of the height of the can to avoid can rattling when the bottom assembly is tilted, and the height of the hollow inside of said bottom assembly above said can-supporting wall being greater than the hollow inside of said top assembly and of a height more than 60% of the height of said can but no more than 75% of the height of said can to leave at least 25% of the top of the can free, whereby to facilitate drinking directly from the can while it lies in the bottom assembly; said top assembly forming a recess that receives at least the upper 25% of the height of said can.
Claim 2
Dependent Claim

A beverae cooler which can keep a beverage-filled can of predetermined diameter cool for an extended period of time while facilitating the drinking of a beverage from the still-cold can comprising: a hollow heat insulated container bottom assembly which includes a bottom end and side walls, and having a hollow inside with a can-supporting wall for supporting the bottom of said can; a hollow heat insulated container top assembly which includes a top end, and which includes side walls which closely mate with the side walls of said bottom assembly to form a can-holding container which avoids the passage of air between the outside and inside of the container to thereby avoid convective heating; said bottom assembly formed to closely surround said can along most of the height of the can to avoid can rattling when the bottom assembly is tilted, and the height of the hollow inside of said bottom assembly above said can-supporting wall being greater than the hollow inside of said top assembly and of a height more than 60% of the height of said can but no more than 75% of the height of said can to leave at least 25% of the top of the can free, whereby to facilitate drinking directly from the can while it lies in the bottom assembly; said top assembly forming a recess that receives at least the upper 25% of the height of said can.
Claim 3
Dependent Claim
63 words
The cooler described in claim 1 wherein: said bottom assembly includes a refrigerant element which can fit into the hollow inside of said bottom assembly and lie at the bottom of said hollow inside, said element having a periphery and a raised top of smaller width than said periphery, for reception in a recess at the bottom of a typical carbonated beverage can.
Claim 4
Dependent Claim
74 words
The cooler described in claim 1 wherein: said container bottom assembly and container top assembly each includes a cup-shaped liner of molded foam and a hard plastic cup surrounding said liner, one of said hard plastic cups having a lip portion which is instepped and the other cup formed to fit closely over said instepped lip portion, said instepped lip portion fitting between the foam liner and the lip portion of the other assembly.
Claim 5
Dependent Claim
93 words
The cooler described in claim 5 wherein: the cup of said top assembly is the cup which has an instepped lip; said bottom assembly cup-shaped foam liner has open and closed ends, the closed end being closely held in at least slight interference fit in the corresponding hard plastic cup so the liner does not fall out when the open liner end faces down, but there is a space between a top portion of the cup and liner of the bottom assembly, which can receive the instepped lip of the top assembly cup.
