Abstract

A method of molding a large returnable container includes a heat treatment step for subjecting a thick preform formed of a polyester resin or a primary blow-molded article to intermediate blow molding with heating to obtain an intermediate molded article, and a final blow molding step that includes subjecting the intermediate molded article that has shrunk to final blow molding with heating to obtain a large returnable container. The heat treatment step includes disposing the preform or the primary blow-molded article in a heat treatment mold, and pressurizing the preform or the primary blow-molded article so that a shoulder and a body obtained by blow molding close contact to a cavity surface of the heat treatment mold, and are subjected to a heat treatment, the shoulder being heated at a low temperature as compared with the body.
