A cross head mounted at an end portion of an extruder for extruding a parison between a pair of elements of a metallic mold and a filling nozzle lifting apparatus having a filling nozzle are provided in parallel, and opening and closing of the metallic mold by a mold clamping apparatus, back and forth movement of the mold clamping apparatus between a parison receiving position and a filling position by a metallic mold feeding apparatus, upward and downward movement of the filling nozzle and back and forth movement of a parison cutter of a parison cutting apparatus are electrically operated. Further, a metallic mold body of the metallic mold is formed from a ventilation material, through which air in the metallic mold is sucked by vacuum to expand the parison. Furthermore, a clean air box is constructed so that it can accommodate the filling nozzle, and clean air is jetted from a jetting hole provided in a lower wall of the clean air box so that a clean air atmosphere may be provided above the metallic mold.
