Abstract
Abstract A beverage cooling arrangement having an inner receptacle defined by a closed end, an open end and a wall disposed between the open and closed ends. An outer encasement partially encases the inner receptacle, and the encasement is joined at the upper end to the inner receptacle along the open end thereof forming a cavity between the inner receptacle and the encasement. A layer of cellular compressible heat-insulating material is disposed within the cavity adjacent the encasement. A solid gel refrigerant is disposed within the remainder of the cavity between the insulation layer and the receptacle. A base is secured to the outer encasement so as to completely seal and isolate the cavity from the outside environment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
An insulated beverage cooling container comprising: an inner receptacle for receiving a beverage, the receptacle having a closed end and an open end and a wall disposed between said open and closed ends; an outer encasement encasing the inner receptacle, said encasement having an upper end joined to the inner receptacle adjacent the open end thereof and a rigid exterior wall surrounding the wall of the inner receptacle and forming thereby a closed cavity between the inner receptacle and the encasement; a layer of cellular, compressible heat-insulating material within the cavity secured to the inside surface of the exterior wall of the encasement; and a solid gel refrigerant disposed within the cavity between the compressible insulation layer and the wall of the receptacle, said gel being in direct contact with the compressible insulation layer and having a freezing temperature of about 30° F., the compressible insulation layer being capable of compressing and expanding under corresponding expansion and contraction of the gel as it undergoes a freeze/thaw cycle.
Claim 2
Dependent Claim
167 words
An insulated beverage cooling container comprising: an inner receptacle for receiving a beverage, the receptacle having a closed end and an open end and a wall disposed between said open and closed ends; an outer encasement encasing the inner receptacle, said encasement having an upper end joined to the inner receptacle adjacent the open end thereof and a rigid exterior wall surrounding the wall of the inner receptacle and forming thereby a closed cavity between the inner receptacle and the encasement; a layer of cellular, compressible heat-insulating material within the cavity secured to the inside surface of the exterior wall of the encasement; and a solid gel refrigerant disposed within the cavity between the compressible insulation layer and the wall of the receptacle, said gel being in direct contact with the compressible insulation layer and having a freezing temperature of about 30° F., the compressible insulation layer being capable of compressing and expanding under corresponding expansion and contraction of the gel as it undergoes a freeze/thaw cycle.
Claim 3
Dependent Claim
13 words

Claim 7
Dependent Claim
11 words
The container of claim 4 wherein the encasement comprises heat-insulating cardboard.
Claim 8
Dependent Claim
28 words
The container of claim 6 wherein the lower end of said encasement forms the closed end of the receptacle, said lower end of the encasement comprising particle board.
Claim 9
Dependent Claim
28 words
The container of claim 6 wherein the lower end of said encasement forms the closed end of the receptacle, said lower end of the encasement comprising polyvinyl chloride.
Claim 10
Dependent Claim
36 words
The container of claim 1 wherein the refrigerant gel consists essentially of about 15% starch, less than about 1% borax, and less than about 1% of a non-toxic preservative, by weight, with the balance being water.
