- the predetermined angle is 90 degrees.
- the conveying means 150 has a rotating plate (not shown).
- a neck mold 151 (described below) is attached to the rotating plate.
- the rotating plate is configured to rotate with the neck mold 151 holding the preform 20, thereby conveying the preform 20 to each of the injection molding section 110, the temperature adjustment section 120, the blow molding section 130, and the removal section 140.
- the injection molding section 110 is equipped with an injection molding die.
- the injection molding die includes at least an injection cavity die (not shown) that defines the shape of the outer surface of the preform 20 (specifically, the outer surfaces of the body 22 and bottom 23), and an injection core die (not shown) that defines the shape of the inner surface of the preform 20 (specifically, the inner surfaces of the body 22, bottom 23, and neck 21).
- the neck die 151 which is also part of the conveying means 150, is also part of the injection molding die.

- the temperature adjustment mold 121 forms the inner wall surface of the temperature adjustment cavity (the storage space for the preform 20).
- the temperature adjustment cavity corresponds to the shape of the outer wall surface (outer surface) of the preform 20.
- the rod member 122 is configured to be displaceable in the vertical direction.
- the rod member 122 is configured to be inserted inside the preform 20.
- the fitting core member 123 contains the rod member 122 concentrically, is displaceable in the vertical direction, and is configured to be able to abut against the neck portion 21 of the preform 20.
- the fitting core member 123 contains the lower portion of the rod member 122 (the portion inserted into the preform 20) so that it protrudes from the lower end of the fitting core member 123.
- the position of the first vent 122a that is blocked by a closing member can be adjusted based on the thickness distribution of the container after blow molding, making it easy to adjust the cooling location and cooling strength of the preform 20 according to various containers. This allows the manufacturing apparatus 100 to flexibly (adaptably) cool the preform 20.

さらに、ロッド部材122の第1の通気口122aが、上下方向または周方向の一部の領域にて使用不可(アルミテープ等の閉鎖部材で塞ぐ等)に設定されることで、圧縮空気による胴部22の冷却部位を局所的に調整することや胴部22に対する冷却強度を任意に調整することが可能となる。様々な樹脂製容器30の製造を可能とするためには、各容器設計に応じた温度分布となるように、プリフォーム20を温調することが必要である。本開示のロッド部材122の一部の第1の通気口122aが塞がれることにより、様々な温度分布のプリフォーム20を提供することが可能となるので、製造装置100におけるカスタマイズ性が向上する。
