Abstract

PURPOSE:To manufacture a plastic vessel capable of clamping double wound by thinning only a flange part, by a method wherein the vessel having the flange part is molded by a hot molding by making use of a plastic sheet possessing a thickness suitable for formation of the vessel, the flange part of the vessel is molded again into a thickness suitable for the double wound clamping by the press hot molding and simultaneously with hot molding or after the molding the flange is stamped out. CONSTITUTION:A plastic sheet possessing a thickness necessary for formation of a vessel is heated and a molded product is molded by hot molding method. Although the side 6 and bottom 7 of a cross section of the one vessel 5 endures sufficiently pressure to be applied to them at the time of double wound clamping, a flange 8 is not suitable for the double wound clamping as a thickness d1 of the same is too thick. The heated vessel 5 is put into a heated mold 9. Then a heated plug 10 comes down from the upper part and the flange 8 is pressed down. At a point of time when the flange has become a predetermined thickness the plug 10 is raised. The flange is stamped out by a mold 14 possessing a blade 13 so that a width W of the same becomes a predetermined one. The vessel to be obtained can be sealed up tightly by performing the double wound clamping of the flange with a metallic lid.
