Document Type and Number:
WIPO Patent Application WO/2004/048077
Kind Code:
A1
Abstract:
A mounting structure of open&sol close valves in a sealed body, wherein the open&sol close valves (2) mounted on the sealed body (1) formed of soft resin sheets (1a, 1b) and allowing air to be filled therein are stuck on one sheet (1a) forming the sealed body (1) at a fixing seal part and not stuck on the other sheets (1b) at the fixing seal part, whereby, since the open&sol close valves (2) are always fitted closely to the one sheet (1a) even when air is filled into the expansion part (12) of the sealed body (1), wrinkles are prevented from occurring on the open&sol close valves (2) to leak air through the wrinkles.
