Inflatable article of footwear or bladders for use in inflatable articles of manufacture
First Claim
1. An inflatable article of footwear, comprising:
- an inflatable bladder, said inflatable bladder comprising;
(a) a first film having a first side and a second side, wherein said first side of said first film has an area that is texturized and corresponds in shape to an inflatable bladder configuration;
(b) a second film adhered to said first film such that said texturized area is positioned between said first film and said second film, but said first film and said second film are not adhered in said texturized area, thereby forming at least one inflatable compartment corresponding in shape to said inflatable bladder configuration and having a sealed peripheral edge; and
(c) an inflation device and a deflation device coupled to said inflatable compartment at an opening through at least one of said first or second films and along a conduit formed between said first and second films, such that said inflation device and said deflation device are located within said sealed peripheral edge.

Abstract
The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second. The inflatable article or bladder of the present invention may be used as or in athletic equipment, for example, including footwear.
