CA 2341418

A no-spill cup (22) and valve assembly (31) which provides an seal against accidental liquid flow. The suck-ing action at the cup spout creates nega-tive pressure against a valve member (37, 39) near the spout (14) having an opening therein, causing the valve member (37, 39) and opening to move off of a pro-truding member, thereby unblocking the opening in the valve. When the open-ing is unblocked, liquid can flow freely through the valve and spout. When not in use, the valve sits in a closed position, with the opening in the valve sitting on a protruding member and pressed against the protruding member's base, sealing off the opening in the valve assembly (31). The closed position provides a seal against fluid leakage during inadvertent spills. The cup assembly allows variable liquid flow rates by rotating the position of the valve assembly in the cover (11) of the cup.

L'invention concerne un gobelet antifuite (22) et un ensemble valve (31) permettant d'assurer une étanchéité contre tout écoulement accidentel de liquide. Le fait d'aspirer au niveau du bec du gobelet crée une pression négative contre une valve (37, 39) située à proximité du bec (14) et pourvue d'une ouverture, provoque l'éloignement de la valve (37, 39) et de l'ouverture par rapport à un élément saillant et, par conséquent, le déblocage d'une ouverture de la valve. Lorsque ladite ouverture est débloquée, le liquide peut s'écouler librement à travers la valve et dans le bec. Lorsque le gobelet n'est pas utilisé, la valve reste en position fermée et l'ouverture de la valve repose sur un élément saillant et appuie contre la base de l'élément saillant, obturant l'ouverture de l'ensemble valve (31). La position fermée assure une étanchéité contre les fuites de fluide accidentelles. L'ensemble gobelet permet d'obtenir des débits de liquide variables par la rotation de l'ensemble valve dans le couvercle (11) du gobelet.
