Abstract: A method for manufacturing a resin container includes: injection molding a preform made of a resin and having a body portion and a bottom portion; adjusting a temperature of the preform manufactured in the injection molding; and a blow molding step of blow-molding the preform having the adjusted temperature to manufacture a resin container. In the injection molding, the preform is injection-molded using an injection mold in which a thickness of the bottom portion is 0.7 to 0.85 relative to a thickness of the body portion. Further, in the adjusting the temperature, a coolant is introduced into the preform to cool the bottom portion of the preform.

Abstract: A method for manufacturing a resin wide-mouthed container includes at least: injection-molding a bottomed preform made of resin; and blow-molding the injection-molded preform. During the injection molding, the preform is injection-molded such that an overhanging section overhanging outward is formed on an outer peripheral section of a first lip section closer to a first body section than a flange section, and while the first lip section, which is provided with the overhanging section, is held by a lip mold, which has a recessed section that engages with the overhanging section, the preform is separated from an injection molding die.
