Abstract
Abstract An inflatable assembly is formed of two superimposed sheets sealed at the peripheries thereof to form a generally closed gas receiving compartment having an external surface and an aperture in that surface for receiving a conduit during inflation. An adhesive pad or strip is provided which covers the aperture and is at least partially attached to the external surface about the aperture with the exception of a zone of initial separation for providing access for the gas conduit into the aperture. The adhesive pad includes adhesive in the region of zone of initial separation in which there is interposed a strip of slip paper which resists adhesion between the pad and the external surface in the zone of initial separation. After inflation, removal of the strip of slip paper allows full closure of the aperture by adhesion between the adhesive pad and the external surface in the zone of initial separation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
181 words
An inflatable assembly comprising: a. A device formed of sheet material having an external surface defining a generally closed gas receiving compartment and having an aperture in said surface for receiving a conduit associated with a source of gas; b. closure means mounted on said external surface covering said aperture and being sealingly attached to said surface about said aperture with the exception of a zone of initial separation dimensioned to provide the gas conduit with access to said aperture, said closure means being provided with adhesive means on the surface of said zone facing said sheet material surface and said aperture; and c. separator means disposed between said zone of said closure means and said sheet material surface to prevent premature attachment therebetween, said separator means being adapted to be removed thereby exposing said adhesive means to said sheet material surface, whereby removal of said separator means subsequent to inflation of said inflatable device and application of pressure to said closure means in the region of said zone of initial separation seals said aperture to prevent escape of gas therethrough.
Claim 2
Dependent Claim
181 words
An inflatable assembly comprising: a. A device formed of sheet material having an external surface defining a generally closed gas receiving compartment and having an aperture in said surface for receiving a conduit associated with a source of gas; b. closure means mounted on said external surface covering said aperture and being sealingly attached to said surface about said aperture with the exception of a zone of initial separation dimensioned to provide the gas conduit with access to said aperture, said closure means being provided with adhesive means on the surface of said zone facing said sheet material surface and said aperture; and c. separator means disposed between said zone of said closure means and said sheet material surface to prevent premature attachment therebetween, said separator means being adapted to be removed thereby exposing said adhesive means to said sheet material surface, whereby removal of said separator means subsequent to inflation of said inflatable device and application of pressure to said closure means in the region of said zone of initial separation seals said aperture to prevent escape of gas therethrough.
