<p>A storage and drinking container for pressurized beverages includes 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 surface 4 on the inside neck of the 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 cap 5 and ring 12 act on rotation of the ring to axially separate the ring 12 from the cap 5, releasing the fingers 8 from under the lip 3 and permitting the lid to be removed. A drinking vessel with a wide neck can be reliably sealed without the necessity to provide screw threads on the outer surface of the vessel 1.</p> |
