<p><P>PROBLEM TO BE SOLVED: To prevent air in an air chamber from leaking outside, and to extend a use life of a gas pouch. <P>SOLUTION: An air seal consist of outer films laminated on the upper and lower sides and inner films held between the outer films. A space line is formed between the upper end and lower end of two inner films by a heat-sealing means, two inner films form an air supply channel between the upper end and space line, and two inner films form at least one air chamber between the lower end and space line. Further, the inner films are joined at the position of the space line, and at least one air suction channel is therein formed, and a buffer chamber is formed between two outer films and inner films after penetrating the air supply channel and air chamber and heat-sealing between the upper end of two outer films and space line. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
