A dispensing system is provided and can be embodied in a dispensing closure (100, 200, 300, 400) for a container having an opening. The system includes a unitary, resiliently flexible, molded valve array structure (130, 230, 330, 430) for being sealingly disposed on the container over the container opening. The valve array structure (130, 230, 330, 430) includes an impervious membrane (132, 232, 332, 432). The valve array structure also includes a plurality of resiliently flexible, slit valves (140, 240, 340, 440) molded unitary with the membrane (132, 232, 332, 432). Each valve (140, 240, 340, 440) has a normally closed dispensing orifice which opens when the pressure in the interior of the container exceeds the pressure on the exterior of the valve by a predetermined amount. The valves can be arranged to discharge parallel streams, diverging streams, or converging streams.
L'invention concerne un système de distribution, et plus particulièrement, un système de fermeture de distribution (100, 200, 300, 400) pour un conteneur pourvu d'une ouverture. Ce système comprend un ensemble de clapets moulés, élastiques et unitaires (130, 230, 330, 430) prévu pour fermer avec étanchéité l'ouverture du conteneur. Cet ensemble de clapets (130, 230, 330, 430) comprend une membrane imperméable (132, 232, 332, 432). Cet ensemble de clapets comprend aussi une pluralité de clapets à fentes élastiques (140, 240, 340, 440) moulés de manière unitaire avec la membrane (132, 232, 332, 432). Chaque clapet (140, 240, 340, 440) présente un orifice de distribution normalement fermé qui s'ouvre lorsque la pression à l'intérieur du conteneur excède la pression sur l'extérieur du clapet, selon une quantité prédéterminée. Les clapets peuvent être placés de ùanière à libérer des courants parallèles, des courants divergents ou des courants convergents
