PRESSURISABLE BEVERAGE VESSELS

摘要

An improved pressurisable wide mouthed vessel is provided which is capable of storing beverages under pressure and also of being used as a drinking vessel. The wide mouthed drinking vessel (2) is closed by a closure (12) urging a seal (16) to sealingly engage the vessel (2). The closure (12) is so configured that when the vessel (2) is pressurised, the closure (12) is deformed to transmit additional pressure to the seal (16) to effect tighter sealing engagement with the vessel (2). The closure (12) has pressure release means for venting the vessel (2) in order to release the pressure on the seal (16), and so allow the closure (12) to be more readily removed from the mouth (6) of the vessel.
