    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.

    摘要: To effectively prevent occurrence of stretching unevenness during blow molding using a liquid as the pressure medium without significantly modifying the structure of a device, provided is a blow molding device including: a metal mold used for blow molding; and a blow nozzle that tightly communicates with a mouth tubular portion of a bottomed tubular preform, the liquid as the pressure medium being supplied into the preform through the blow nozzle. The blow nozzle is provided, at a lower end portion thereof, with an engaging tubular piece that is inserted into the mouth tubular portion, and the engaging tubular piece has a length by which a lower end of the engaging tubular piece extends further downward than a neck ring in a state where the blow nozzle is in communication with the mouth tubular portion, the neck ring being provided around a lower end of the mouth tubular portion.
