A valve for a flexible liquid-container has a hollow cylindrical body including a bowl-shaped or through-shaped diaphragm, circumferentially sealed to an inside wall of the tubular body. A convex side of the diaphragm faces an inlet side of the valve and a concave surface of the diaphragm faces an outlet side of the valve. The diaphragm has at least one slit extending therethrough. A cylindrical tube-spring of elliptical cross-section inserted into the tubular body exerts tension on the slit for holding the slit closed when the valve is not in use.

alve d'un contenant souple à liquide ayant un corps cylindrique creux comprenant une membrane en forme de cuvette ou d'auge, scellée à sa circonférence à une paroi interne du corps tubulaire. Un côté convexe de la membrane fait face au côté admission de la valve et une surface concave de la membrane fait face au côté refoulement de la valve. La membrane a au moins une fente qui la traverse. Un tube-ressort cylindrique de section elliptique inséré dans le corps tubulaire exerce une tension sur la fente afin de maintenir cette dernière fermée lorsque la valve ne sert pas.
