Patent

CA 2227186

A drinking cup container (12) has a cover (14) which is formed with a drinking spout (22) at one side and a vent (28) at the other. Elements (26, 30) extend down from under the spout and the vent. A flow control element (40) is provided and made of elastomeric material having a pair of spaced cavities (42, 44) on one side, each cavity having a floor (46, 48) at the bottom thereof. The cavities receive in frictional engagement, respectively, the lower ends of the elements. This engagement supports the flow control element with the floor of each cavity in sealed relation to its element. Each floor has a passage (54, 56) which is normally closed, but opens on the occurrence of a pressure differential on opposite sides of the floor.

Ce récipient (12) à boire, de type gobelet, présente un couvercle (14) pourvu d'un côté d'un bec (22) et de l'autre d'un orifice (28). Des éléments (26, 30) s'étendent vers le bas, en dessous et à partir du bec et de l'orifice. On a monté un dispositif (40) de régulation de l'écoulement, lequel est réalisé dans un matériau élastomère et présente, sur un côté, une paire de cavités (42, 44) espacées l'une de l'autre, chaque cavité comportant un fond (46, 48) au niveau de sa partie inférieure. Ces cavités reçoivent respectivement, par emboîtement frictionnel, les extrémités inférieures des éléments. Cet emboîtement soutient le dispositif de régulation de l'écoulement, le fond de chaque cavité formant une étanchéité avec son élément correspondant. Chaque fond présente un passage (54, 56) qui est normalement fermé, mais s'ouvre lorsque survient un différentiel de pression au niveau des côtés opposés du fond.
