Zusammenfassung: | In a method for manufacturing a resin container, in the adjusting the temperature of the preform, the preform is accommodated in a cavity mold, a refrigerant introduction member is inserted into the preform, the refrigerant introduction member including a first flow path and a second flow path which are different in introduction or discharge position of a refrigerant, the preform is cooled by bringing the preform into close contact with an inner wall of the cavity mold at a pressure of the refrigerant introduced from the refrigerant introduction member. When the preform is cooled, cooling is performed by switching between a first cooling blow for introducing the refrigerant from the first flow path and discharging the refrigerant from the second flow path and a second cooling blow for introducing the refrigerant from the second flow path and discharging the refrigerant from the first flow path. |
