ABSTRACT:
An expandable pouch for applying a pressure to a material to be dispensed from a container wherein two sheets of a fluid impervious material are permanently joined together at their edges and divided into a plurality of compartments by semi-permanent peelable strips. One of the compartments is divided into sub-compartments with fluid communication being provided between two sub-compartments. One of a two component chemical gas generating system is located in each of the two sub-compartments so that when the pouch is inverted, the chemicals combine to start generating gas to force open the peelable strips.
