Abstract:
A membrane-type inflation nozzle composed of at least two nozzle membranes overlaid on each other, at a part of two lateral edges of the two nozzle membranes being longitudinally seamed to form a seam line so as to define at least one air passage between the two nozzle membranes communicating an inner side with an outer side, an inner wall of at least one nozzle membrane at an open end of the air passage being disposed with adhesive material on which a release sheet is attached, whereby the nozzle is applicable to an inflatable envelope, serving as inflation nozzle, after the envelope is inflated, an internal pressure making the nozzle self-close, the release sheet being torn away, whereby the adhesive material at the open end is able to adhere corresponding inner walls of the nozzle membranes adjacent to the open end to each other so as to achieve a more tightly sealing effect.
