摘要： A blow molding device includes a blow molding mold to which a preform is fitted, a blow nozzle that is fitted to a mouth tubular portion of the preform, and a pressurized liquid supply unit configured to supply a pressurized liquid to the blow nozzle, the preform being to be molded into a shape conforming to a cavity of the mold by filling the liquid into the preform through the blow nozzle. The blow nozzle includes a central hole and a plurality of peripheral holes having an inner diameter smaller than an inner diameter of the central hole and arranged to surround the central hole. The liquid is filled into the preform through the central hole and the plurality of peripheral holes.

摘要： A blow molding device includes a blow nozzle to be inserted tightly into a mouth tube section of preform when the preform is inserted in a mold. The blow molding device also includes a pressurized liquid feeding unit and feeds a pressurized liquid from the pressurized liquid feeding unit into the preform through the blow nozzle to form a container into an expanded shape along a cavity of the mold. A valve mechanism, provided at a downstream end of a feed channel for the liquid in the blow nozzle, can open and close the feed channel so that when the valve mechanism is in a closed state, the liquid circulates between the feed channel and the pressurized liquid feeding unit, and when the valve mechanism is in an open state, the pressurized liquid is fed through the feed channel into the preform.
