A pressurization pouch having a pressurization system therein activated by the application of a vacuum underpressure to the outside surfaces of the pouch is inserted into a dispensing container through an opening in a lid portion of the container. Upon the sealing of the container by the attachment of a valve member to the container lid at the opening thereof, a vacuum generator is coupled to the valve member to generate negative pressure inside the dispensing container, thereby causing the pouch to expand under the pressure of a predetermined amount of air disposed therein. Upon that initial expansion, the pressurization pouch is further inflated owing to the action of the pressurization system. Upon complete inflation of the pressurization pouch, the pouch forms a liner in the dispensing container. A flowable product is then injected into the dispensing container through the valve member. The pouch comprises a pair of compartments releasably sealed and separated from one another by a seam having a sharp point formed by a pair of straight-line seam segments joining one another at an acute angle.

Method for prepressurizing dispensing container and for filling

A balloon storage and inflation assembly comprises a circular inflatable balloon containing a pair of chemical reactants separated from one another, one of the reactants being held in a burstable container. The balloon is placed between two plates of a support structure, the burstable container and a portion of the balloon being disposed in a recess formed by two aligned openings in the plates. The support structure is further provided with a pair of doors hingedly secured to respective ones of the plates along edges of the openings. The doors are swung into the openings to compress the burstable container and to facilitate a rupture thereof upon the striking of one of the doors by a fist or other object.
