Abstract: A blow molding device for blow molding preforms into a predetermined shape. The blow molding device includes a batch-type mold provided with cavities, a heating furnace that heats preforms while the preforms are arranged in series, a transfer machine that simultaneously transfers the preforms as a batch to the cavities of the mold after the preforms are heated and sent out sequentially from the heating furnace, and a pressurized liquid feeder that feeds pressurized liquid to the preforms after the preforms are arranged in all of the cavities of the mold and the mold is closed.

Abstract: A liquid blow molding device for liquid blow molding a resin preform into a container having a predetermined shape. The liquid blow molding device includes a mold in which the preform is disposed; a stretch rod that axially stretches the preform disposed in the mold (; and a pressurized liquid supply that supplies a pressurized liquid to the preform. The liquid blow molding device operates such that the amount of the liquid supplied from the pressurized liquid supply to the inside of the preform before completing the stretching of the preform by the stretch rod (22) is 50% or less of the amount of the liquid to be filled in the container after the completion of the liquid blow molding.

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.
