Abstract: A blow molding device in which pressure is accumulated in advance in a cylinder, which is used for providing pressurized an air space about a mouth of a preform to be molding into a container within a mold using a pressurized liquid. Pressure is also accumulated in advance in an accumulator. When a pressurized liquid is supplied into the preform, the opening-closing valve of the accumulator is opened to thereby apply the accumulated pressure within the accumulator to the liquid supplied into the preform, and the opening-closing valve is closed to thereby allow the accumulated pressure within the cylinder to pressurize the air space.

Abstract: A blow molding apparatus for mitigating a difference in flow rates of a liquid supplied from a blow nozzle to a preform. The blow molding apparatus includes a blow nozzle that mates with an open tube portion of a preform and a seal body that opens and closes the blow nozzle. A filling head extends along an axial direction of the blow nozzle and is provided at one end with a liquid supply channel connected to the blow nozzle and with a liquid introduction channel connected to the liquid supply channel from the side. A pressurized liquid supply unit is connected to the liquid introduction channel and supplies a pressurized liquid to the liquid introduction channel. A spiral guide groove is provided around an axial center of the liquid supply channel in an inner peripheral surface of the liquid supply channel.

Abstract: A preform formed from polypropylene or high density polyethylene and with which a container of a desired shape can be precisely molded by liquid blow molding. When formed of polypropylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 2.25-4.34, inclusive, and in the radial direction by a stretch ratio of 1.95-5.00, inclusive. When formed of high density polyethylene as a closed-bottom cylinder shape having an open end section and a body section, the preform is molded into the container by stretching the body section in the axial direction by a stretch ratio of 1.69-2.50, inclusive, and in the radial direction by a stretch ratio of 2.26-5.07, inclusive.
