Abstract:
A blow molding device is provided in which a preform is injection-molded. The injection-molded preform is temperature-controlled by a temperature adjusting unit, and the temperature-adjusted preform is blow-molded, wherein the temperature adjusting unit has a multistage structure in which an uppermost stage has the highest temperature structure, and the mold surface temperatures of lower stages and other than the uppermost stage are set to be 10° C. or more lower than the glass transition temperature of the preform.
