PROBLEM TO BE SOLVED: To provide a blow molding apparatus for blow molding a preform by a liquid that simplifies its structure while having a function for sealing a bottle body.SOLUTION: The present invention is a blow molding apparatus comprising a mold 1 into which a preform P is installed and a blow nozzle 2 connected to a mouth cylindrical part P3 of the preform P and supplying a pressurized liquid from the blow nozzle 2 into the preform P. The blow molding apparatus includes blow nozzle moving means that raises and lowers the blow nozzle 2 along an axis of the preform P. The blow nozzle 2 has cap mounting means that fixes and retains a cap C, sealing a bottle body B when lowered by operation of the blow nozzle moving means, on a mouth cylindrical part B3 of the bottle body B.SELECTED DRAWING: Figure 5 |
