Abstract:
1. A spout assembly for connecting to an opening of a container to empty a fluid from the container, which fluid may be under a gas pressure, the spout assembly comprising: a spout that includes (i) a mouthpiece through which fluid can pass and (ii) a tube, the tube being in fluid communication with the mouthpiece so that fluid can pass through the tube and the mouthpiece; a valve assembly including (i) a valve housing including a valve seat and (ii) a valve that is resiliently urged against the valve seat by an urging force; a membrane device that includes (i) a membrane device opening and (ii) a fixed seal that seals between the spout and the valve housing; and a seal structure that maintains a seal between the membrane device opening and the tube; said membrane device flexing toward an interior of the container when suction is applied to the tube via the mouthpiece, and forcing the valve away from the valve seat in opposition to the urging force.
