ABSTRACT:
A flexible closed plastic pouch forming an expulsion means for supplying dispensing pressure, holding a product, closed by an aerosol valve. A plurality of pocket members disposed at spaced positions within said pouch with their openings facing the interior of the pouch. Each pocket member having an extension of a predetermined length attached at its end to the interior of first of two facing wall members of the pouch. Each pocket member enclosing a predetermined quantity of first component of a two-component gas generation system and being releasably closed by one of a plurality of closure members, each of said closure members having an extension of a predetermined length attached at its end to the interior of the second of the two facing walls of the pouch. The pouch contains a second component of said two-component gas generation system and a starting means encapsulated within a delay means or device to initially generate a predetermined quantity of pressurizing gas after a delay of a predetermined period of time. The pressurizing gas inflates and expands the pouch within the container under pressure. Due to the dispensing of the product, the pouch expands further and causes sequential separation of the pocket members from their closure members and serial opening of each pocket member to add predetermined quantities of aliquot of the first component to the second component and further generate additional quantities of pressurizing gas. The internal pressure within the container is maintained substantially within a range of predetermined maximum and minimum pressure levels until dispensing the product from the container is complete, at which time, the walls of the pouch substantially lining the interior of the container. A device inside the container prevent the pouch from expanding before the product is filled into the container.
