Patent

CA 2387776

A dispensing structure is provided for discharging the contents from the interior of a container (22). The structure includes a body (40) for extending from the container (22). The body (40) defines a dispensing opening (56) and a sealing surface (58) around the dispensing opening (56). A lid (30) is provided for movement between open and closed positions. The lid (30) has a frame defining a lid dispensing passage (72) through the lid (30). The lid (30) has a mounting flange (76) extending inwardly adjacent the dispensing passage (72), and the lid (30) has a valve (80) mounted to the lid flange (76) across the dispensing passage (72). The flexible valve (80) has self-sealing slits (84) which open to permit flow therethrough in response to increased pressure on the side of the valve (80) facing the container (22) when the lid (30) is closed. The valve (80) has a lower flange (108) which is below the lid flange (76) and which sealingly engages the body sealing surface (58) when the lid (30) is in the closed position.

L'invention concerne une structure de distribution destinée à évacuer le contenu d'un conteneur (22). La structure comprend un corps (40) destiné à former un prolongement sur le conteneur (22). Ce corps (40) définit une ouverture de distribution (56) et une surface d'étanchéité (58) autour de l'ouverture de distribution (56). Un couvercle (30) destiné à être mis dans une position ouverte ou fermée possède un cadre définissant un passage de distribution (72) à travers le couvercle (30), une nervure (76) de montage qui s'étend vers l'intérieur, adjacente au passage de distribution (72), et une valve (80) montée sur la nervure (76) de montage, dans le passage de distribution (72). La valve (80) flexible possède des fentes auto-obturantes (84) qui s'ouvrent pour permettre l'écoulement à travers la valve en réponse à une augmentation de la pression sur le côté de la valve (80) se trouvant du côté conteneur (22) lorsque le couvercle (30) est fermé. La valve (80) possède une nervure inférieure (108) qui se trouve en-dessous de la nervure (76) du couvercle et qui s'engage hermétiquement sur la surface d'étanchéité (58) lorsque le couvercle (30) est en position fermée.
