A non-venting valve (3) and dispensing package (1) for fluid products and the like includes a container (2) of the type having an interior volume which reduces as fluid product is dispensed from the package (1). A self-sealing dispensing valve (3) has a marginal portion (4) sealing about an associated discharge opening (5) in the container (2), and a valve head (6) with an orifice (7) which shifts between open and closed positions in response to the application and release of pressure on and/or within the container (2). A vent resisting member (8) retains the orifice (7) in the closed position after each dispensing of fluid product from the container (2) to prevent ambient air from being drawn back through the orifice (7) into the container (2).
L'invention concerne un clapet empêchant l'entrée d'air (3) et un conditionnement de distribution (1) adaptés aux produits fluides ou semblables. Le système comprend un contenant (2) dont le volume intérieur réduit au fur et à mesure de la distribution du fluide à partir du conditionnement (1). Un clapet de distribution auto-obturateur (3) présente une partie marginale (4) formant un scellement autour d'un orifice de distribution associé (5) du contenant (2) et une tête de clapet (6) présentant un orifice (7) qui se décale entre une position ouverte et une position fermée lorsque l'on exerce une pression sur et/ou dans le conteneur (2) et que l'on relâche celle-ci. Un élément résistant (8) maintient l'orifice (7) fermé après chaque distribution de produit fluide provenant du contenant (2) pour éviter que l'air ambiant ne soit aspiré à travers l'orifice (7) dans le contenant (2).
