  • Patent number: 10189200
    Abstract: Stretch blow station tooling for stretch blowing at least one parison into a molded article, with such parison including a handle. The tooling comprises at least one blow mold assembly including first and second blow mold halves shiftable between an open position and a closed position. The first and second blow mold halves each include a body cavity surface formed therein. In the closed position, the body cavity surfaces of the first and second blow mold halves are aligned to define a blow cavity for receiving at least a portion of the parison. The tooling further comprises a plunger assembly including a plunger configured to be selectively positioned within the blow cavity. When the plunger is positioned within the blow cavity, the plunger is configured to contact the handle of the parison.

  • Patent number: 9962881
    Abstract: Injection stretch blow molding tooling for forming at least one parison and at least one stretch blown article having an integral handle. The tooling includes at least one cavity block, a body mold supported within the cavity block, a handle mold supported within the cavity block, and a thread split assembly positioned adjacent to said cavity block. The thread split assembly includes first and second thread split halves shiftable between an open position and a closed position. As such, the body mold, the handle mold, and the thread split assembly cooperatively define a parison-forming cavity, with such parison-forming cavity including a body cavity for forming a body of the parison and a handle cavity for forming a handle of the parison.
