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.

Abstract: A producing method for a resin container includes a first injection molding step of injection-molding an intermediate molded body that has a bottomed cylindrical shape and is made of resin, a second injection molding step of injection-molding a resin material into the intermediate molded body to produce a multilayer preform in which a resin layer is laminated on the intermediate molded body, and a blow molding step of blow-molding the multilayer preform in a state of having residual heat from injection molding to produce a resin container. The multilayer preform is formed such that a bottom portion is thicker than a body portion. In the blow molding step, at least one surface of the bottom portion of the multilayer preform is pressed with a mold, and a three-dimensional pattern corresponding to the mold is transferred to a thick bottom portion of the resin container.

Abstract: A temperature adjustment mold for adjusting a temperature of a preform that is injection-molded, has a bottomed shape, and is made of resin includes one or more adjusting portions that face a part of an outer peripheral surface of a body portion of the preform and locally heat a predetermined portion in a circumferential direction of the preform. The adjusting portion is disposed such that a gap is formed in the circumferential direction, and an attachment position is adjustable in the circumferential direction.

Abstract: A method for manufacturing a resin container includes: injection molding a preform made of a resin and having a body portion and a bottom portion; adjusting a temperature of the preform manufactured in the injection molding; and a blow molding step of blow-molding the preform having the adjusted temperature to manufacture a resin container. In the injection molding, the preform is injection-molded using an injection mold in which a thickness of the bottom portion is 0.7 to 0.85 relative to a thickness of the body portion. Further, in the adjusting the temperature, a coolant is introduced into the preform to cool the bottom portion of the preform.
