Abstract: An aerosol valve assembly including a valve member disposed within a chamber defined by a body, the body being in sealing engagement with a gasket. The valve member is normally biased into engagement with the gasket and has a stem extending through the gasket to define an outlet. The biasing means for maintaining the valve in its normally closed position is a generally flat spring element disposed and supported transversely in the shell and in expansive bearing contact with the lower end of the valve member.

Abstract: This application describes and illustrates a method of making an aerosol valve tip and stem assembly and the interlocked assembly. The interlocked assembly is comprised of a tip and stem, one being a hard material defining a recess or notch, and the other being of a soft cold-flowable material that is caused to coldflow into the notch when the two members are telescopically assembled. When the members are assembled, the soft cold-flowable material cold-flows into the notch to interlock the members and to make disassembly thereof difficult.
