  • Patent number: 4936473
    Abstract: This relates to a container, particularly adapted for receiving a hot-fill product. Most particularly, the container is a blow molded plastic container with the principal plastic material being a polyester resin. Critical areas of the container have walls of a laminated construction with preferably at least five layers of which two layers is a moisture barrier layer. The polyester resin primarily utilized, PET, is very sensitive to moisture pickup and by utilizing the moisture barrier layers, the moisture pickup of the primary resin may be reduced with a resultant reduction in the shrinkage and distortion of such container when hot filled.
