RESIN MOLDING DEVICE, METHOD OF MANUFACTURING RESIN MOLDING, HOLLOW MOLDING, AND CONTAINER

摘要

A resin molding device (200) holds a hollow molding which is provided with a container-shaped body section and a cylindrical opening neck section (2), and the hollow molding is held so as to be rotatable about the axis of the opening neck section (2). A section (4) to be gripped by opening neck gripping sections (13, 14) of molds (11, 12) of the resin molding device (200) is formed on the periphery of the opening neck section (2). The outer peripheral shape of the section (4) to be gripped which extends about the axis of the opening neck section (2) is non-circular. The inner peripheral shape of the opening neck gripping sections (13, 14) in a state in which the opening neck gripping sections are combined is adapted to have a shape matching with the outer peripheral shape of the section (4) to be gripped. In bringing the molds (11, 12) close to each other to combine the molds and causing the opening neck gripping sections (13, 14) to grip the section (4) to be gripped, the opening neck gripping sections (13, 14) press the section (4). This rotates the hollow molding to correct the rotational angle of the hollow molding.
