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.

Abstract: An inflatable assembly comprising a device having a body, with a neck terminating in a free end, with an opening extending from the free end and communicating with the body which is capable of being inflated. Closure means is provided and includes an adhesive element mounted on the neck and protruding or extending beyond the free end thereof, with the closure means adapted to be moved from an open position in which a tube extends into the neck such that a gas entering the device through the tube inflates the body to a closed position in which the adhesive element which extends beyond the free end is sealed when the tube is removed from the device. Guide means extends intermediate the tube and the adhesive element, and is adapted to be retracted from the closure means in conjunction with the tube such that the adhesive element when compressed is sealed together beyond the free end and the closure means is in its closed position so as to obtain a sealing of the neck to prevent gas from escaping therethrough.
