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 wide-mouthed container includes at least: injection-molding a bottomed preform made of resin; and blow-molding the injection-molded preform. During the injection molding, the preform is injection-molded such that an overhanging section overhanging outward is formed on an outer peripheral section of a first lip section closer to a first body section than a flange section, and while the first lip section, which is provided with the overhanging section, is held by a lip mold, which has a recessed section that engages with the overhanging section, the preform is separated from an injection molding die.

Abstract: A method for manufacturing a resin container includes a first step of accommodating an injection-molded bottomed resin preform in a temperature-adjusted mold and adjusting a temperature of the preform by the mold, a second step of moving the mold by a predetermined amount in an axial direction with respect to the preform by a lifting and lowering device and then stopping the mold, and causing an air ejection part arranged on an upper surface side of the mold to face a portion of the preform to be cooled, a third step of ejecting air from the air ejection part to locally cool the portion to be cooled of the preform positioned in the axial direction, and a blow molding step of blow molding the preform whose temperature has been adjusted through the first to third steps and manufacturing a resin container.
