Production device for resin container, production method for resin container, and mold for temperature adjustment

A manufacturing method for a resin container, comprising:

• an injection molding step of injecting a molten resin into an injection cavity defined by an injection-molding mold and forming a preform;
• a temperature adjusting step of adjusting a temperature of the preform to a temperature suitable for blow molding;
• and
• a blow molding step of blow-molding the preform whose temperature has been adjusted, wherein
• the temperature adjusting step includes ejecting or sucking air through an air flowing port formed in an outer periphery of a rod member inserted into the preform, and
• a plurality of the air flowing ports, as viewed along a direction perpendicular to an axial direction of the preform, are formed in the axial direction.

A mold for temperature adjustment configured to adjust a temperature of a preform formed by injection molding to a temperature suitable for blow molding, the mold for temperature adjustment comprising:

• a temperature adjusting mold constituting an inner wall surface of a temperature adjusting cavity;
• and
• a rod member configured to be inserted into the preform, wherein
• a plurality of air flowing ports configured to eject or suck air, as viewed along a direction perpendicular to an axial direction of the preform, are formed in the rod member in the axial direction.
