Abstract: 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.

Abstract: A container mold includes: a split mold that has a mold space defining a shape of a body portion of a container; and a bottom mold that has a bottom mold surface defining a shape of a bottom surface of the container and is movable forward and backward with respect to the split mold. The split mold includes a bottom mold reception portion that is communicated with a bottom portion side of the mold space and receives the bottom mold. When the bottom mold is closed with respect to the split mold, a space between a surface of the bottom mold reception portion facing the bottom mold surface and the bottom mold surface is a space that defines a shape of a structure protruding in a radial direction of the container.
