Abstract: A self-closing closure for use with a container, the closure opening automatically upon the application of opening pressure to the contents of the container and being self-closing upon the release of pressure. A pair of resilient discs or diaphragms are employed which in the closed position have their convex surfaces facing each other. One of these discs carries the valve opening and the other disc supports the valve stem which projects into and seals the opening in the closed position of the closure. Upon the application of opening pressure to the container contents, the resilient discs move axially of the closure and the convex surfaces change to concave surfaces. The valve stem is drawn away from the opening. The large axial movement of the discs is attained with minimal pressure yet secures a large opening area for dispensing the contents.

Abstract: A self-closing structure has a tube having a free end surrounded by a funnel shaped end of a cylinder supported on a diaphragm capable of being mounted on the open top of an elastically yielding container and upon compressing said container forcing the contents thereof against said diaphragm the funnel shaped end moves along said tube allowing said content to be extruded and upon the release of the container said funnel shaped end returns below said tube free end and is closed thereby. The release of the container due to its elastically creates a suction thereof drawing air down said tube into said container. A valve can be mounted below said tube normally closing the same, but being opened only for the suction in said container.
