Abstract

PURPOSE:To provide the subject method of injection molding a theremoplastic polyester into a bottomed parison, thereafter carrying out biaxial elongation blow- molding thereby to obtain a container for food and the like, and other liquids and powdery materials without shrinkage on the wall surface. CONSTITUTION:A theremoplastic polyester resin 1 is injected from an injection molding machine 2 to a metal mold 6 consisting of a male mold 3, a lip mold 4 and female mold 6 thereby to obrain a bottomed parison 7. Then, the parison is transferred to a heating pot 9 while the screw part of the bottomed 7 is being held in the lip mold 4, and the inner and outer surfaces of the parison are heated by a heating core 10 and heaters 11 and 12 of the heating pot. Further, the parison is transferred to an elongation blow mold 13, and elongated by an elongation rod 14. Then, pressure air 15 is blown into the inner part of the mold to carry out blow molding, thereafter the elongation blow mold 13 is withdrawn, and the lip mold 4 is split to remove a molded article 7, thus the object container is obtained.
