PURPOSE:To reduce the cost of a container by raising the manufacturing efficiency of the container to a large extent, by bringing a process from the molding of a preform by injection molding to that of the container by stretching blow molding to a continuous operation system. CONSTITUTION:A mold clamping apparatus 18 is operated to extend a mold clamping rod 19 downwardly and the injection core 17 and the injection cavity 13 of an injection operation part A are inlaid through a holding mold 12. A resin is injected in this mold 12 from an injection nozzle 15 to mold a preform 40. Subsequently, this preform 40 is revolved by a rotary driving apparatus 7 to be moved to a stretching blow part B. Herein, the preform 40 is stretched to the axial direction by a stretching rod and air is blown from a blow core to mold the preform 40 into a molded product 41. Next, this molded product 41 is revolved to a take-out operation part and a take-out apparatus is operated to push a mold opening plate into a split mold 11 to open the mold and the molded product 41 is demolded from the holding product 41. |
