Abstract
Abstract An improved beverage container holder manufactured by a process including the steps of providing a cylindrical outer cup of foam material and press fitting a cylindrical inner cup within the outer cup after filling the annulus formed therebetween with a refreezable fluid. The cylindrical inner cup includes a radially extending flanged region at the open end which comprises an inwardly and downwardly tapered rib circumferentially disposed about the cup for engaging and becoming embedded within the side walls of the cylindrical outer cup to form a cylindrical seal therearound. A resilient outer ring means is snapped over the juncture between the respective open ends of the inner and outer cup to secure the seal therebetween. The refreezable fluid contained therein is preferably bled of excess pressure imparted during the assembly insertion of the inner cup into the fluid containing outer cup by squeezing an intermediate portion of the assembled cup configuration to force excess fluid and/or air through the interface between the inner and outer cup juncture prior to receiving the outer ring thereover. In this manner, excess pressure is not retained within the assembled structure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
217 words
An improved refrigerated holder for a beverage container of the type including a cylindrical outer cup of insulative foam material closed on one end and open on the other, a cylindrical inner cup positioned within said outer cup with a height less than that of the outer cup, 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 at the open end for positioning near the open end of the outer cup to close the annular space, and a freezeable fluid positioned within the annular space between the inner walls of the outer cup and the outer walls of the inner cup for absorbing heat from the walls of a beverage container positioned within the inner cup when the fluid is frozen to cool the beverage within the container; the improvement comprising: a sharp circumferential edge region formed on the outer periphery of the radially extending flange of the inner cup having a diameter greater than that of the inner diameter of the outer cup to be embedded in the foam wall of the outer cup and effect a sealing of the annular fluid containing space.
Claim 2
Dependent Claim
217 words
An improved refrigerated holder for a beverage container of the type including a cylindrical outer cup of insulative foam material closed on one end and open on the other, a cylindrical inner cup positioned within said outer cup with a height less than that of the outer cup, 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 at the open end for positioning near the open end of the outer cup to close the annular space, and a freezeable fluid positioned within the annular space between the inner walls of the outer cup and the outer walls of the inner cup for absorbing heat from the walls of a beverage container positioned within the inner cup when the fluid is frozen to cool the beverage within the container; the improvement comprising: a sharp circumferential edge region formed on the outer periphery of the radially extending flange of the inner cup having a diameter greater than that of the inner diameter of the outer cup to be embedded in the foam wall of the outer cup and effect a sealing of the annular fluid containing space.
Claim 3
Dependent Claim
81 words
An improved refrigerated holder for a beverage container as set forth in claim 1 which also includes: a circular elastic retaining ring having an unstressed diameter slightly less than that of the outer cup positioned about the open end of the outer cup to apply a radially inward force to said outer cup walls and securely embed the sharp circumferential edge of the inner cup radial flange into the inner walls of the outer cup and reinforce the sealing engagement therebetween.
Claim 4
Dependent Claim
54 words
An improved refrigerated holder for a beverage container as set forth in claim 2 wherein said circular elastic retaining ring includes a radially inwardly protruding circular ridge positioned in general alignment with the sharp outer edge of the inner cup radial flange to assist in sealing the juncture between the inner and outer cups.
Claim 5
Dependent Claim
63 words
An improved refrigerated holder for a beverage container as set forth in claim 1 wherein the radially extending flange of the inner cup also includes a frustroconical ramp portion extending inwardly and downwardly from the upper and outer sharp peripheral edge to facilitate relative axial movement between the inner and outer cups during insertion of the inner cup down into the outer cup.
Claim 6
Dependent Claim
25 words
An improved refrigerated holder for a beverage container as set forth in claim 1 wherein the outer cup is formed of expanded bead polystryene foam.
Claim 7
Dependent Claim
202 words
A holder for cooling a beverage container during consumption: a cylindrical outer cup of foam material having an open and a closed end, said foam being thermally insulative for comfortable handling and elastically resilient for compliance with the physical expansion of a freezeable fluid contained thereby upon freezing of said fluid; a cylindrical inner cup positioned within said outer cup, said inner cup being shorter in height than the outer 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, said inner cup also including a radially extending flange region having a diameter greater than the inner diameter of the outer cup and a sharp circumferential edge embedded in the complaint inner wall of the outer cup to effect a closure seal of said annular space; and a freezeable fluid within the annular space between the outer walls of the inner cup and the inner walls of the outer cup for, upon first being frozen, then absorbing heat through the walls of the inner cup from a beverage container positioned within the inner cup and thereby cool the beverage.
Claim 8
Dependent Claim
202 words
A holder for cooling a beverage container during consumption: a cylindrical outer cup of foam material having an open and a closed end, said foam being thermally insulative for comfortable handling and elastically resilient for compliance with the physical expansion of a freezeable fluid contained thereby upon freezing of said fluid; a cylindrical inner cup positioned within said outer cup, said inner cup being shorter in height than the outer 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, said inner cup also including a radially extending flange region having a diameter greater than the inner diameter of the outer cup and a sharp circumferential edge embedded in the complaint inner wall of the outer cup to effect a closure seal of said annular space; and a freezeable fluid within the annular space between the outer walls of the inner cup and the inner walls of the outer cup for, upon first being frozen, then absorbing heat through the walls of the inner cup from a beverage container positioned within the inner cup and thereby cool the beverage.
