Blow molding device

A blow molding apparatus including:

• a mold for blow molding;
• a blow nozzle configured to be disposed above the mold;
• a pressurized fluid supply unit configured to supply a pressurized incompressible fluid to the blow nozzle;
• and
• a blow nozzle moving unit configured to cause a relative movement of the blow nozzle between a connected position in which the blow nozzle is connected to a mouth tubular portion of a preform that has been placed in the mold and a standby position in which the blow nozzle is upward and away from the mouth tubular portion, wherein
• the preform is molded into a container having a shape corresponding to a cavity of the mold, by supplying the pressurized incompressible fluid into the preform through the blow nozzle which is in the connected position, the blow molding apparatus comprising:
• a drawing member including a drawing port;
• a drawing pump configured to be connected to the drawing member;
• and
• a drawing member moving unit configured to move the drawing member so that the drawing port is positioned below the blow nozzle, after the container has been molded and the blow nozzle has been moved from the connected position to the standby position.
