ABSTRACT:
A self-sealing dispensing valve for use on various containers. It is a simple two-piece device consisting of an outer housing having a dispensing outlet and an inner complemental valve member which ordinarily closes the outlet but which can be moved by finger pressure to open the outlet, and which will automatically return to its closed position when opening pressure is released. The housing has a flexible dome-shaped outer wall which embraces and is attached to a complemental dome-shaped rigid wall at the outer end of the valve member, which also has an axially inwardly extending flared sealing skirt. The skirt normally seats on the outlet, which extends radially through the correspondially tapered housing, but will be displaced axially inwardly to open the outlet, upon inward axial pressure on the outer dome-shaped flexible housing wall. Internal container pressure aids in the normal seating of the valve member.
