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.- - -

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.
