Abstract
A valve for a flexible liquid-container has a hollow cylindrical body including a bowl-shaped or trough-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.
