초록 ▼

A check valve provides a one-way fluid passage from without to within a fluid bladder formed by a pair of plastic sheets sealed together about their periphery. The check valve is formed by a pair of superimposed films of thermoplastic material, generally equal in length, thermally bonded together at predetermined areas to define the fluid passage throughout the length of the valve. Each of the films, adjacent one end thereof, is sealed to one of the outer sheets where the valve enters the bladder by a seal line of wedge shape. Each of the films has a high-gloss, cohesive inner surface and a matte, non-cohesive, outer surface. At least one of the films includes, on its inner surface, a release material disposed at a location which corresponds to the area at the inlet end of the fluid passage through the peripheral seal of the bladder to prevent the fusing together of the films at that area of the seal. The seal in that area has a V-shape with apex pointing in a direction opposite the one-way fluid flow. The terminal ends of the superimposed films extend in surface-to-surface relation into the bladder to provide a “duck-bill”type check valve.

대표청구항 ▼

Combination of a check valve and inflatable bladder defined by upper and lower sheets of synthetic plastic material having a seal forming one and another fluid chamber with a fluid passage therebetween, the check valve comprises two layers of plastic film of generally the same length which are sealed together at their side edges and to opposed inner surfaces of the sheets in said passage and having a channel throughout the length thereof for permitting the one-way flow of fluid from the one chamber of the bladder into the other chamber thereof, each of said layers being characterized by a matte non-blocking outer surface and a glossy inner surface having a blocking tendency a barrier material disposed between said film to prevent the heat-sealing together of the film layers at the location where the check valve extends through the seal between said two sheets.
