Abstract of the Disclosure 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 gen- erator is coupled to the valve member to generate negative pres- sure 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 pressuriza- tion pouch is further inflated owing to the action of the pres- surization 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 com- partments 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.
