ABSTRACT:
The invention relates to a pressure vessel comprising a container of rigid material having a cylindrical portion defining an open mouth which is formed by reversely bending inwardly the end of said cylindrical portion to form a cylindrical flange portion. The curved junction between the flange portion and the cylindrical container portion is a semi-circle, the flange portion extending parallel to the cylindrical container portion beyond a diametrical line between the ends of the semi-circular junction. A closure assembly comprising a cylindrical plug having a reduced diameter sleeve defining an annular shoulder is positioned in said container mouth, with said shoulder engaging the rim of said cylindrical flange, the latter being restrained from transverse inward movement by abutment against said sleeve.
