PURPOSE: To mold a heat-resistant container by an inexpensive compact molding apparatus so that the enhancement of the crystallinity and the reduction of residual stress of a container packed with thermally sterilized high temp. content such as a juice drink can be certainly achieved within a short time and the shape stability of the container at the time of high temp. can be enhanced to prevent thermal deformation. CONSTITUTION: A receiving and taking out part receiving a primary molded product 52 molded by the blow molding of a preform and taking out a final molded product, a heat treatment part 20 bringing the primary molded product received in the receiving and taking out part into contact with the inner wall of a heat treatment chamber 70 while pressurizing the same from the inside thereof in the heat treatment chamber 70 and a final molding part 22 subjecting the intermediate molded product 94 heat- treated in the heat treatment chamber 70 to blow molding in a final blow mold 96 to mold a final molded product are provided. The receiving and taking out part, the heat treatment part 20, the final molding part 22, the rotary plate 16 feeding respective molded products to the receiving and taking out part, a neck support member fixing plate 44 and a neck support member 48 are provided. |
