ABSTRACT:
A vacuum insulated container is produced by sealing the ends of a pair of hollow concentric tubular members. Air is then evacuated from the enclosed space between the members to obtain a vacuum insulating sleeve. An insulated base seals one end of the sleeve while a liner is provided in the interior of the sleeve for receiving food or a beverage. The other end of the sleeve may have various configurations to provide either a wide or narrow mouthed opening.
