Patent

CA 2318899

A dispensing structure is provided for a container (41) that has an opening to the container interior. A membrane (44) initially occludes the container opening. A cover (40) extends over the container opening and over the membrane (44). The cover (40) has a peripheral frame and a panel (87) that is connected to the frame (102). The panel (87) has a dome-like, outwardly convex configuration defining a dispensing aperture and is normally biased outwardly. The panel (87) can be moved to an inverted, inwardly concave configuration. A dispensing valve (45) is disposed in the cover across the dispensing aperture. A penetrator (120) extends from the panel (87) inwardly of the dispensing valve (45) for penetrating the membrane (44) when the panel (87) is in the inwardly concave configuration.

L'invention concerne une structure de distribution pour un récipient (41) pourvu d'une ouverture permettant d'accéder à l'intérieur de ce récipient, une membrane (44) bouchant initialement cette ouverture. Un couvercle (40), destiné à recouvrir cette ouverture et cette membrane (44), est constitué d'un cadre périphérique et d'un panneau (87), lequel est relié audit cadre (102). Ce panneau (87), qui présente une configuration extérieurement convexe en forme de dôme définissant une ouverture de distribution, est normalement sollicité vers l'extérieur, et peut par ailleurs adopter une configuration inverse intérieurement concave. Une soupape de distribution (45) est en outre placée dans le couvercle recouvrant ladite ouverture de distribution. Un dispositif de pénétration (120) s'étend du panneau (87) vers l'intérieur de cette soupape de distribution (45), de manière à pouvoir pénétrer la membrane (44) une fois ledit panneau (87) dans sa configuration intérieurement concave.
