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.

A production apparatus of a two-layer preform including an inner layer preform and an outer layer preform includes: an outer layer cavity mold for injection-molding the outer layer preform. A bottom surface of the outer layer cavity mold is provided with a protrusion for separating the inner layer preform disposed in the outer layer cavity mold from the bottom surface.

Apparatus for producing resin molded article, method for producing resin molded article, and resin molded article

Provided is a method for manufacturing a containermade of resin, the method including an injection molding step S, a temperature adjustment step S, and a blow molding step S. In the temperature adjustment step S, a preformis accommodated in a cavity mold, an air introduction memberis brought into airtight contact with the preform, the air is supplied from a blowing port of the air introduction memberinto the preform, and the air is discharged from a discharge port of the air introduction memberto an outside of the preform, so that the preformis in close contact with an inner wall of the cavity moldand is cooled.
