  • Double-blown pet bottle shaped container having essentially no residual stress and superior heat resistance
    Patent number: 5928742
    Abstract: A biaxially oriented polyethylene terephthalate resin bottle-shaped container, and method of blow-molding the same, is disclosed. The method comprises the steps of heating the body portion of a preform at 90.degree. to 130.degree. C., biaxial-orientation blow-molding the preform in a primary blowing mold heated at 110 to 230.degree. C. to form a primary intermediate molded bottle-shaped piece, heating the primary intermediate molded bottle-shaped piece at 130 to 255.degree. C. or at a temperature which is at least 20.degree. C. greater 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.degree. to 150.degree. 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.

  • Biaxially oriented polyethylene terephthalate resin bottle-shaped container
    Patent number: 5248533
    Abstract: A biaxially oriented polyethylene terephthalate resin bottle-shaped container made by thermally crystallizing a neck portion of a preform, heating the preform, blow-molding the preform to form a primary intermediate molded bottle-shaped piece, raising the temperature of the primary intermediate molded bottle-shaped piece to a temperature greater than the temperature during blow-molding the preform to thermally contract the primary intermediate molded bottle-shaped piece to form a secondary intermediate molded bottle-shaped piece, and blow-molding the secondary intermediate molded bottle-shaped piece to form a bottle-shaped container.
