Patent

CA 2649417

A storage and drinking container for pressurised beverages comprises a drinking vessel (1) having a lip (3) and a lid formed from a cap (5) and retaining ring (12). The cap (5) seals with a sealing surface (4) on the inside of the neck of the drinking vessel and is retained in place by fingers (8) engaging under a lip (3). The fingers 8 are retained in position by a retaining ring (12). Cooperating sets of cammed surfaces (10) and (13) on the cap (5) and retaining ring (12) act on rotation of the retaining ring to axially separate the retaining ring (12) from the cap (5), releasing the fingers 8 from under the lip (3) and permitting the lid to be removed. The invention provides a drinking vessel with a wide neck which can be reliably sealed without the necessity to provide screw threads on the outer surface of the drinking vessel (1).
