Abstract
A unitary blow molded plastic body is described which may be severed to provide a plurality of body sections including a first body section, which may be used to receive a liquid therein, and a second body section which may be attached about a bottom portion of the first section to provide a stabilizing and reinforcing base cup. The compound plastic body formed by the first and second section may be sealed as by an aluminum can end to provide a sealed container capable of containing a pressurized liquid beverage such as soda pop or beer.
Claims28
A beverage container for holding a liquid under pressure comprising:
- liquid receiving means for receiving liquid therein formed from a first portion of a unitary blow molded plastic body;
- cup means fixedly mounted on a bottom portion of said liquid receiving means in enclosing relationship with said bottom portion for providing a stable container base, said cup means being formed from a second portion of said unitary blow molded plastic body;
- and
- lid means for sealingly closing said liquid receiving means.
