Abstract: A temperature adjustment device and a temperature adjustment method for a preform in a blow molding device with which it is possible to reduce a molding cycle time is provided. A temperature adjustment device for a preform in which a hollow rod member is inserted into an injection-molded, bottomed preform retained by a retention member, and a first air circulation path is formed between the preform and the hollow rod member to adjust the temperature of the preform. The temperature adjustment device is characterized in that a flow path adjustment member is fitted and attached to the outer periphery of the hollow rod member, whereby the cross-sectional area of the first air circulation path is partially adjusted and changed.

Abstract: There is provided a resin container including an upper surface portion, a side surface portion connected to the upper surface portion, and a bottom surface portion disposed on a side opposite to the upper surface portion and connected to the side surface portion. A round corner surface portion is formed to the side surface portion. A first folding deformation inducing portion is formed on the round corner surface portion. When the container is viewed from a side surface portion side such that a central axis of the container and the round corner surface portion overlap with each other, the first folding deformation inducing portion is oblique with respect to the central axis.
