  • Patent number: 8192812
    Abstract: Overmolded containers and methods of manufacture thereof are disclosed, which may provide enhanced visual and tactile characteristics, enabling innovative packaging designs, improved grippability and thermal insulation. The containers can be made cost effectively manner, with minimal impact on polymer recycling streams. The methods of making the container include the steps of providing a container preform which comprises a thermoplastic polymer, such as a PET copolymer; overmolding an elastomeric material over at least a portion of the preform to form an overmolded preform; and blow-molding the overmolded preform to form an overmolded container. In one embodiment, the overmolded container is a beverage container.

  • Patent number: 6168041
    Abstract: Tubular containers can be produced by injection stretch blow molding processes. Such processes comprise the biaxial stretching of the preform as the preform is being converted into the tubular container. The preform will be stretched longitudinally by means of a stretch rod and laterally by means of the pressure of the blowing gas. The tubular containers produced by these processes will have burst strengths three to five times that of other tubular containers and can be produced in a thin wall collapsible form. Further, the tubular container will have a tensile strength in the machine direction along a tensile strength in the cross direction greater than other tubes, including laminate tubes, coextruded blow molded tubes and injection stretch tubes. In addition, the tubular containers can be single chamber containers or multichamber containers.
