ABSTRACT:
A system of providing convenient filling and sealing of air cushions at the site of their intended use, such as at a packaging line. A concatenation of inflatable cushions is prepared with each cushion comprising two thin films of a thermoplastic, at least one of which films has a generally central opening. The films are fused together in discrete areas to define a plurality of inflatable chambers between the films disposed around the opening, with each of the chambers having an inlet passageway communicating with the opening. The cushions are shipped uninflated to the site where they are to be used, and are then inflated and sealed on a device which includes a nozzle for simultaneously directing air through the opening of the cushion and the inlet passageways to inflate the chambers, and a means for sealing together the films in a small area around the opening to close the inlet passageways to the chambers.
