    • 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.
    • 吹塑装置包括当将预成型件插入模具中时紧密地插入预成型件的口管部分中的吹塑喷嘴。 吹塑装置还包括加压液体供给单元,并且通过吹塑喷嘴将加压液体从加压液体供给单元供给到预成型件中,以沿着模具的空腔形成容器成扩展形状。 设置在用于吹塑喷嘴中的液体的进料通道的下游端的阀机构可以打开和关闭进料通道,使得当阀机构处于关闭状态时,液体在进料通道和加压的流体之间循环 液体供给单元,并且当阀机构处于打开状态时,加压液体通过进料通道进料到预成型件中。
