摘要： A container production method by liquid blow molding. The method includes a head space forming step of forming a head space in the upper portion of a container, in which, with the container disposed in a cavity, a bottom panel portion molded into an upward convex shape on a bottom of the container is inverted by pushing it down with a pushing rod and is plastically deformed into a downward convex shape.

摘要： A liquid blow molding apparatus for liquid blow molding a resin preform into a container having a prescribed shape. The apparatus includes a blow molding mold in which the preform is disposed; a blow nozzle that engages in an opening of the preform; a pressurized liquid supply that supplies a pressurized liquid to a supply path that is connected to the blow nozzle; and a seal member that is provided inside the supply path and opens and closes the supply path with respect to the blow nozzle. The pressurized liquid supply is configured to start supplying the pressurized liquid to the supply path after the seal member has begun to open.

摘要： A blow molding mold is adapted to be mounted to a blow molding device and having a cavity surface. The blow molding device has a pressurized liquid supply function of supplying a pressurized liquid to stretch the preform toward the cavity surface and also has a head space defining function of defining head space in the container by drawing back a part of the liquid filled into the container through a blow nozzle or by withdrawing a stretching rod from the container filled with the liquid. The cavity surface includes a bottom forming surface, a trunk forming surface, a shoulder forming surface, and a mouth forming surface, and the trunk forming surface includes a flattened portion that, in the transverse section, has a flattened shape.
