ABSTRACT:
In an aerosol type container having a pressure chamber, a product containment sack of an impervious flexible material is centrally retained. The aerosol container is provided with an annular opening defined by an annular lid curl. The lid curl is interlockingly engaged by a collar portion of the sack. A modified valve assembly is sealingly secured within a neck protruding from the sack collar. The sack collar acts as a one-way valve allowing a pressurizing agent to be introduced for the purpose of maintaining a desirable pressure within the container pressure chamber. The invention pertains to pressurizing, sealing and sack retainment of such dispensers.
