Further, the pressure-resistant container 1 comprises a cylindrical pressing member 5 which is screwed into an inner peripheral surface 4b of the mount ring 4, an inner peripheral surface b (FIG. 3) of the mouth ring 4 which exposes between the inner shell 3 and the pressing member 5, a first seal (an O-ring 10 and an liquid sealant 11a) which peripherally contacts with the inner shell and the pressing member, a valve 6 having a screw part 6b which screws into an inner periphery 4c of the mouth ring at outside of the container than the pressing member and an inner end part 6c which is inserted in the hole part of the pressing member and a second seal (an O-ring 12) to seal between an outer peripheral surface of the inner end part 6c and an inner peripheral surface of the pressing member.
