ABSTRACT OF THE DISCLOSURE A method of blow-molding a biaxially oriented polyethylene terephthalate resin bottle-shaped container is disclosed. The method comprises the steps of heating the body portion of a preform at 100 to 120°C, biaxial- orientation blow-molding the preform in a primary blowing mold heated at 110 to 230°C to form a primary intermediate molded bottle-shaped piece, heating the primary intermediate molded bottle-shaped piece at 130 to 255°C or at a temperature which is 20°C or higher than the primary blowing mold temperature to form a secondary intermediate molded bottle-shaped piece, and blow-molding the secondary intermediate molded bottle-shaped piece in a secondary blowing mold heated at 100 to 150°C to form a bottle-shaped container. The temperature of the secondary blowing mold is several degrees greater than the maximum temperature the molded bottle-shaped container will be subjected to during use, The bottle-shaped container has no stress remaining from biaxial orientation blow-molding and has a high heat resistance temperature value.
