Abstract
Abstract Means for insulating and chilling a canned beverage such as beer or soft drink including a cylindrical cup-shaped liner structure disposed within a conventional foam beverage can holder and lying within a portion of the annular "dead air" cavity between a beverage can situated therein and the side walls of the foam holder. The outer wall of the inner cup wall and the inner wall of the outer foam cup walls define an annular space containing a reusable refrigerant. The reusable refrigerant is a freezable fluid, preferably a liquid chemically treated into a gellatenous state for being frozen in conventional refrigerator freezers. In the frozen state the gel will chill and keep chilled beverage disposed within a container placed within the inner cupshaped liner. The top portion of the liner is constructed for light press fit engagement with the side walls of the foam holder for sealably containing the gel therein in a non-frozen state. A conventional circular plastic ring closes the top intersecting edges between the foam holder and the inner liner and facilitates the entrapment of any dead air between the beverage container and the inner cup wall.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
222 words
A refrigerated holder for a beverage container of the type including a cylindrical outer cup of insulative material closed on one end and open on the other, the circular edges of the open end being covered by a circular retaining ring including a first portion extending radially across the top edges and into the open end with flap portions to position a cylindrical beverage container in axial alignment with said outer cup and a second, cylindrical portion extending from the top of the cup down the outer wall to retain the ring in position around the cup, the improvement comprising: a cylindrical inner cup having an outer diameter less than the inner diameter of the outer cup to define an annular space therebetween and an inner diameter for receiving the cylindrical walls of a beverage container therein, said inner cup also including a radially extending flange region at the open end for positioning adjacent the top edges of the outer cup beneath the retaining ring to seal the annular space therebeneath; a freezable fluid positioned within the annular space between the outer walls of the inner cup and the inner walls of the outer cup for absorbing heat from the walls of a beverage container positioned within the inner cup when said fluid is frozen to cool the beverage within the container.

Claim 3
Dependent Claim
32 words
An improved refrigerated holder for a beverage container as set forth in claim 1 wherein the outer cup is formed of polystyrene foam and the inner cup is formed of molded plastic.
Claim 4
Dependent Claim
32 words
An improved refrigerated holder for a beverage container as set forth in claim 1 wherein the outer cup is formed of polystyrene foam and the inner cup is formed of thin-walled metal.
Claim 5
Dependent Claim
20 words
An improved refrigerated holder for a beverage container as set forth in claim 1 wherein said freezable fluid comprises water.
Claim 6
Dependent Claim
