Abstract: A manufacturing apparatus for manufacturing a resin container including an injection molding part configured to injection-mold a preform, and a temperature adjustment part configured to adjust a temperature of the preform molded in the injection molding part. The manufacturing apparatus is configured to blow-mold the preform whose temperature has been adjusted in the temperature adjustment part. The injection molding part includes an injection core mold and an injection cavity mold, and both the injection core mold and the injection cavity mold include a flow path connected to a chiller in which coolant is configured to flow to cool the preform such that the preform is inserted into the temperature adjustment part in a state where an outer surface temperature of the preform is higher than a glass transition temperature of a material constituting the preform by 30° C. or higher and 60° C. or lower.

Abstract: A forming mold is used when forming a preform, which has a neck portion and a barrel portion, and whose barrel portion is filled with a molding material over the entire axial direction thereof, by injection molding; forming a space part in the barrel portion of the preform to convert the preform into an intermediate molded product; and blow-molding the intermediate molded product to form a hollow container which is a final molded product. The forming mold is equipped with a boring rod which is inserted from the neck portion side into the barrel portion of the preform to form the space part of at least a predetermined depth in the barrel portion.

Abstract: - - - A method of producing a resin container includes injection-molding a resin intermediate molded body of bottomed cylindrical shape as a first injection-molding, injection-molding a resin material outside the intermediate molded body as a second injection-molding, to produce a multilayer preform in which a resin layer is layered on an outer peripheral side of the intermediate molded body, and a blow-molding the preform in a state of containing residual heat from injection-molding to produce a resin container having a bottom portion thicker in wall thickness than a body portion. A portion of the inner peripheral side of the intermediate molded body, the portion reaching a bottom portion of the intermediate molded body, has a tapered region in which the wall thickness increases toward the bottom portion.- - -
