Abstract: Provided is a resin container manufacturing method including: an injection molding process of injection molding a plurality of preforms along a predetermined arrangement direction; a temperature adjustment process of adjusting a temperature of the preform; and a blow molding process of molding a resin container from the preform. After the injection molding process, the preform and the container are conveyed along a conveying direction intersecting the arrangement direction over the temperature adjustment process and the blow molding process. The temperature adjustment process includes a first temperature adjustment process of adjusting the temperature of the preform, a second temperature adjustment process of adjusting the temperature of the preform under a condition different from that of the first temperature adjustment process, and a fine adjustment process of finely adjusting the temperature of the preform.

Abstract: A blow molding machine includes a support member that supports a mold component and a moving mechanism that moves the support member to a projecting position toward the outside of the machine and to a storing position. The machine includes a first fixed fulcrum shaft. The support member includes a base end portion rotatably supported by the first fixed fulcrum shaft and a free end portion having a first movable fulcrum shaft. The moving mechanism has rotatably interconnected links. One link is rotatably supported by the movable fulcrum shaft. In the projecting position, the links are maintained linearly by a first angle fixing tool to serve as a leg portion that supports the support member's free end portion.
