Abstract
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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
236 words
An inflatable assembly comprising: A. A device having an inflatable body with a neck thereon, said neck terminating in a free end and having an opening extending from said free end and communicating with the interior of said body which is capable of being inflated; B. a tube initially extending at least partially into said neck through said opening; C. closure means including an adhesive element adhesively mounted externally on said neck and having a substantial, adhesive-coated area protruding beyond said free end, said closure means being adapted to be moved from an open condition in which said tube extends into said neck such that a gas entering said device through said tube inflates said body to a closed condition in which at least a portion of said coated area of said adhesive element which extends beyond said free end is sealed to another portion thereof when said tube is removed from said opening to seal said neck opening; D. guide means extending intermediate a surface of said tube and a portion of said adhesive-coated area of said adhesive element, said guide means including surface means adapting it to be retracted from said closure means with the tube such that said adhesive element when compressed is sealed together beyond said free end and said closure means is in its closed condition so as to obtain a sealing of said neck to prevent gas from escaping therethrough.
Claim 2
Dependent Claim
236 words
An inflatable assembly comprising: A. A device having an inflatable body with a neck thereon, said neck terminating in a free end and having an opening extending from said free end and communicating with the interior of said body which is capable of being inflated; B. a tube initially extending at least partially into said neck through said opening; C. closure means including an adhesive element adhesively mounted externally on said neck and having a substantial, adhesive-coated area protruding beyond said free end, said closure means being adapted to be moved from an open condition in which said tube extends into said neck such that a gas entering said device through said tube inflates said body to a closed condition in which at least a portion of said coated area of said adhesive element which extends beyond said free end is sealed to another portion thereof when said tube is removed from said opening to seal said neck opening; D. guide means extending intermediate a surface of said tube and a portion of said adhesive-coated area of said adhesive element, said guide means including surface means adapting it to be retracted from said closure means with the tube such that said adhesive element when compressed is sealed together beyond said free end and said closure means is in its closed condition so as to obtain a sealing of said neck to prevent gas from escaping therethrough.
