ABSTRACT:
A fluid-impervious self-inflatable sealed pouch containing separately compartmented first and second gas generating components which, upon admixture in successive discrete quantities, generate gas, causing the pouch to expand gradually from an initial collapsed condition to an ultimately fully expanded condition. Within the pouch is a mechanically rupturable solvent-containing member optimally including a measured quantity of one of said components and the other said component is enclosed by a water-soluble film barrier of polyvinyl alcohol, methylcellulose or the like, additional inner receptacles within the pouch contain measured quantities of said one component for successive release into said admixture caused by expansion of said pouch. A method is provided whereby the pouches are formed in a continuous manner from a plurality of film-like materials fed to respective successive work stations at which receptacles and/or containers are formed, components introduced, permanent and/or releasable seals are formed, water soluble barriers provided and completed pouches delivered in finished form in interconnected and/or severed, independent condition for further utilization.
