ABSTRACT:
The method of filling and pressurizing an aerosol type container having a fill-opening which comprises introducing a dispensable fluid product into the container for storage therein, projecting an expansible sac having an open end into the container through its fill-opening, overlapping the open end of the sac upon the fill-opening, introducing a pressurized fluid into the sac for storage therein, successively disposing a valve mechanism into the container to overlie the sac open end and closing the sac and fill-opening for sealing the dispensable fluid within the container and for sealing the pressurized fluid within the sac and closing the container; and extending a communicating means from the valve mechanism through the sac establishing communication between the valve mechanism and the fluid product for isolated passage of the fluid product therethrough.
