Abstract
A disposable pressure vessel includes a gas valve containing cylindrical cap encircled by an O-ring. The cap is bonded to an annular flared portion of a generally cylindrical rubber bladder and is disposed in a hollow cylindrical housing such that the cap compresses the flanged portion of the bladder against a shoulder in the cylindrical housing. The cap is held in place by three equally circumferentially spaced, lanced portions of the cylindrical housing and the O-ring seals the interior of the cylindrical housing from the exterior.
