Abstract
Difficulties in retaining can holders in conventional vehicular drink holders are eliminated in a vacuum insulated can holder that includes a cup-shaped metallic outer liner having an upper opening, an opposite bottom and a generally cylindrical side wall extending upwardly from the bottom to the opening. A similarly configured cup-shaped metallic inner liner is nested within the outer liner and spaced therefrom to define vacuum space between the two. The outer liner has an outer diameter just less than the inner diameter of a conventional vehicular beverage holder while the inner diameter of the inner liner is just greater than the outer diameter of a conventional metal beverage can.
Claims6
A vacuum insulated can holder comprising:
- a cup-shaped metallic outer liner having an upper opening, an opposite bottom and a generally cylindrical side wall extending upwardly from said outer liner bottom to said opening;
- a cup-shaped metallic inner liner nested within said outer liner and having an upper opening, an opposite bottom and a generally cylindrical side wall extending upwardly from said inner liner bottom to said opening;
- the cylindrical side walls of said inner and outer liners merging at said opening and being scaled thereat;
- the side wall of said inner liner being located radially inward of the side wall of said outer liner to define a space therebetween;
- the bottom of said inner liner being located above the bottom of said outer liner to define a space therebetween;
- a vacuum in raid spaces and being maintained by the sealing between the inner and outer liners at said openings;
- at least a lowermost section of said outer liner having an outer diameter lust less than an inner diameter of a conventional vehicular beverage holder;
- the inner diameter of said inner liner side wall being just greater than the outer diameter of a conventional metal beverage can;
- said lowermost outer diameter being less than 2.890 inches, said inner liner inner diameter being greater than 2.600 inches, and the height of said inner liner cylindrical side wall is being less than 4.840 inches.
A vacuum insulated can holder comprising:
- a cup-shaped stainless steel outer liner having an upper opening, an opposite bottom and a generally cylindrical side wall extending upwardly from said outer liner bottom to said opening;
- a cup-shaped stainless steel inner liner nested within said outer liner and having an upper opening, an opposite bottom and a generally cylindrical side wall extending upwardly from said inner liner bottom to said opening;
- the cylindrical side walls of said inner and outer liners merging at said openings and being sealed thereat;
- the side wall of said inner liner being located radially inward of the side wall of said outer liner to define a space therebetween;
- the bottom of said inner liner being located above the bottom of said outer liner to define a space therebetween;
