    Abstract: A bottom section has a ground contact section which is provided at the outer periphery of a body section, and a raised bottom section which is provided inside the ground contact section. The raised bottom section is provided with a recessed section provided at the center, and a connection section which connects the recessed section and the ground contact section. The recessed section side end of the connection section is configured to be located closer to the neck side than the ground contact section side end when inner pressure is at ambient pressure.

    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: The neck crystallization system includes a rectangular stage, a plurality of sprockets that are disposed on the stage, and an endless member that is fitted around the plurality of sprockets. A transfer path that is formed in an area in which the endless member is disposed, includes first to fourth linear transfer paths. A plurality of heating sections provided along at least the first to third linear transfer paths, a cooling section disposed along at least the fourth linear transfer path, a molded article supply section that supplies the molded article at a position on the upstream side of the plurality of heating sections, and a molded article removal section that removes the molded article at a position between the cooling section and the molded article supply section, are provided along the transfer path in which a plurality of transfer members that respectively support the molded article are transferred.

    Abstract: A wide-neck synthetic resin container has a neck, a body and a bottom. A top side of the neck is sealed by a cap. The neck includes a neck tubular section, an engagement section protruding outward therefrom and engaging the cap, and a flange protruding outward at the top side. The flange protrudes less than the engagement section. The neck's top side includes a first top side formed by the neck tubular section, and a second top side formed by the flange that is the same height level with the first top side and increases an area of the top side. The neck tubular section has a uniform thickness at an area immediately below the flange and an area where the engagement section is formed. A thickness of the flange is smaller than that of the neck tubular section, and the neck has been crystallized.

    Abstract: A blow molding method includes a primary blow molding step that molds a preform (200) in a primary blow mold (300A) that includes a primary temperature control section (330) to obtain an intermediate molded article (202), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article (204) that has shrunken in a secondary blow mold that includes a secondary temperature control section (430) to obtain a final molded article. The primary blow molding step cools a first intermediate molding region of the intermediate molded article that follows a neck using a first primary temperature control section, and the shrinkage step shrinks a second intermediate molding region of the intermediate molded article of which the temperature is controlled by a second primary temperature control section.
