Beschreibung
Zusammenfassung:	A method for manufacturing a resin container includes: an injection molding step of injection molding a preform made of a resin and having a body portion and a bottom portion; a temperature adjustment step of adjusting a temperature of the preform manufactured in the injection molding step; and a blow molding step of blow-molding the preform having the adjusted temperature to manufacture a resin container. In the injection molding step, 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 temperature adjustment step, a coolant is introduced into the preform to cool the bottom portion of the preform.
