ABSTRACT:
A convex type bottom with a bearing rim for bottles for industrial gases, obtained by hot forging a steel billet, has the lower outer surface consisting of a central circular flat area (2), a first frustoconical annular area adjacent the central area (2), inclined upwards, a second frustoconical annular area adjacent the first frustoconical annular area, inclined downwards, and a subvertical frustoconical area (6) radiused, on the one side, to the second frustoconical annular area and, on the other side, to the flat surface (7) of the bearing rim (8). Provided on the inclined frustoconical annular areas are corrugations (3,4,5). Such a configuration of the bottom permits the defects to be eliminated due to creeping of the material during forging.
