ABSTRACT:
A sealed package for pressurizing the contents of dispensing containers. The package contains chemicals which react to develop gas pressure to expand the package when in the dispensing container. A series of sequentially rupturable pockets add further increments of internal pressure as dispensing proceeds. These pockets, and additional pockets containing chemicals for initiating package pressurization, are formed in an outer film heat-sealed to a second outer film to define the package. The rupturable pockets are covered with a tape to maintain the chemicals isolated until rupture is effected by progressive lift-off of the tape as the package expands.
