Abstract:
1. A vacuum insulated beverage dispenser, comprising: an inner liner with a generally hollow cylindrical liner body, a closed bottom closure and a top closure with an inlet opening; a single-piece outer housing with a hollow cylindrical housing body with a housing top, said outer housing enveloping the hollow cylindrical body of the inner liner, a relatively larger closed bottom closure and a relatively larger top closure with a housing top opening generally aligned with the inlet opening, said outer housing body enveloping the inner hollow cylindrical liner body in spaced relationship to form an evacuated gap between the hollow cylindrical bodies, the closed bottom closures and the top closures; and a slanted surface of said relatively larger top closure of the outer housing body extending downwardly and outwardly from the top opening of the outer housing to a surrounding outer edge of the surface joined to the hollow cylindrical housing body at a location adjacent to but spaced beneath the top end of the hollow cylindrical housing body to strengthen the relatively larger top closure against distortion from net pressure created by evacuation of the evacuated gap.
