ABSTRACT:
An inflatable assembly formed of two superimposed sheets sealed at the peripheries thereof to form a generally closed gas receiving compartment including opposing sheet portions having generally aligned initially unsealed edges which form an opening for receiving a gas conduit during inflation. Adhesive or a double-sided adhesive strip is provided on one of the sheet portions facing the other sheet portion. Premature adhesion between the sheet portion is prevented by a removable protective strip disposed between the adhesive surface and the facing sheet portion. After inflation and removal of the gas conduit and the protective strip, application of pressure to the sheet portions seals the opening to prevent escape of gas therethrough.
