Abstract
A drinking vessel includes a cover and a mouthpiece, the mouthpiece having at least a flexible portion which in its unflexed state engages a plug extending up through the mouthpiece. When the flexible portion is flexed, for example by suction or pressing or biting with lips or teeth the flexible portion flexes out of engagement with the plug, forming a liquid passage. As a result a self-sealing drinking vessel is provided which provides liquid on user demand.
