Abstract:
A self-closing valve for the dispensing of flowable media from a container having;a curved membrane, the curvature of which is directed toward the flowable media in the closed position and which curves outwardly into a dispensing position upon pressure being generated in the container, a support segment which holds the valve to said container, a connecting wall arranged between said membrane and said support segment, a slitting provided in said membrane which opens in the dispensing position, wherein said slitting is arranged such that upon the deformation of the membrane from the closed position to the dispensing position induced by the application of pressure to the container, elastic resilient forces are generated within the membrane which cause said membrane to retract from said dispensing position to said closed position upon depressurization, said connecting wall between said support segment and said membrane is disposed with an annular section which is arranged substantially in a common plane with said support segment or on a plane which is parallel to same, said slitting being configured such that it has one slit, and at least one of said slits is interrupted so as to create a material bridge, whereby the length of said slit interruption is smaller, preferably substantially smaller, than the total length of the respective slit.
