Inflatable assembly with edge closure

Claim 1

An inflatable assembly comprising: a. A device formed of sheet material defining a generally closed gas-receiving compartment including opposing sheet portion having generally aligned initially unsealed edges which define an opening to said compartment; b. an external and reusable conduit adapted to be associated with a source of gas, said conduit being inserted into said opening prior to inflation; c. adhesive means provided on a surface of at least one of said sheet portions facing the other of said sheet portions; and d. separator means disposed between said adhesive means and said other of said sheet portions and defining, with said other sheet portion, a passage for said external and reusable conduit, said separator means being provided with a slip surface on at least one surface thereof facing said adhesive means which does not adhere to said adhesive means and can slideably move relative to said adhesive means when in abutment therewith to prevent premature attachment of said sheet portions to each other and being adapted to be removed thereby exposing said adhesive means to said other of said sheet portions, whereby removal of said separator means and said external and reusable conduit subsequent to inflation of said inflatable device and application of pressure to said sheet portions seals said opening to prevent escape of gas therethrough.
