Patent

CA 2399613

A dispensing system is provided for two, constituent, fluent materials which are stored separately and then combined in a dispensing process to form a combination product. The dispensing system includes a container (30) having at least two interior storage chambers (40), and each chamber has a separate discharge opening (50). Associated with each discharge opening (50) is a separate, flexible valve (32). Each valve has an initially closed dispensing orifice which opens in response to a differential between the pressure acting against the side of the closed valve facing toward the associated discharge opening and the pressure acting against the side of the closed valve facing away from the associated discharge opening. In a preferred embodiment, a top (38) is provided downstream of the valve (32). The top (38) is movable between (1) a closed position to occlude a dispensing flow path downstream of the valves, and (2) an open position which permits flow to be discharged from the system.

L'invention concerne un système de distribution destiné à deux matières fluides stockées séparément puis mélangées au cours d'un processus de distribution de manière à former un produit composé. Ce système de distribution comprend un récipient (30) comportant au moins deux chambres de stockage intérieures (40), chaque chambre étant munie d'ouvertures de décharge séparées (50). Un robinet souple (32) est associé à chaque ouverture de décharge (50). Chaque robinet comprend un orifice de distribution initialement fermé s'ouvrant en réponse à une différence entre la pression agissant sur le côté du robinet fermé orienté vers l'ouverture de décharge associée et la pression agissant sur le côté du robinet fermé orienté à l'opposé de l'ouverture de décharge associée. Dans un mode de réalisation préféré, un couvercle (38) est installé en aval du robinet (32). Ce couvercle (38) peut se déplacer entre (1) une position fermée, d'où l'obstruction d'un chemin d'écoulement de distribution en aval des robinets, et (2) une position ouverte permettant à la matière de s'écouler hors du système en question.
