Abstract
A self-generating gas pressure apparatus such as an expandable closed pouch for placement within a container from which a fluid therein is to be dispensed under pressure. The apparatus has a plurality of internal compartments formed by pressure-rupturable seals and containing respective chemical compounds which when mixed upon adjacent-compartment seal rupture produce a gas. At least one of two adjacently-housed chemical compounds has in addition thereto a nucleating agent such as diatomaceous earth which acts to more rapidly force gas generated in the reaction of the adjacently-housed chemical compounds out of solution and thereby provide an operative pressure to the apparatus more quickly.
