Abstract: An injection station of an injection blow molding machine and a method for forming parisons and molded articles. The injection station includes a die plate with a keyway formed through a least a portion of a surface of the die plate. The keyway separates front and back portions of the surface of the die plate. The injection station further includes a resin injection tooling comprising a draw bar, with at least a portion of the draw bar operable to be positioned within the keyway of the die plate, a base plate secured to a back side of the draw bar and operable to be secured to the back portion of the surface of the die plate and, and a manifold secured to a top of the base plate, with the manifold being configured to discharge resin into cavities to form the parisons.

Abstract: An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having upper and lower die sets and a plurality of upper and lower mold half blocks each attached to a respective die set. Each of the upper mold half blocks has a corresponding lower mold half block with which it cooperatively defines one or more cavities for forming the exterior shape of the body of one or more of the parisons. The individual, independent attachment of the mold half blocks to the die sets allows easy individual replacement of faulty or worn mold blocks. Further, such an independent attachment configuration also permits the mold half blocks of each die set to be spaced from one another, so as to reduce thermal expansion problems and ease dimensional tolerances required for the width of the mold half blocks.

Abstract: An injection nozzle that can be used in an injection blow molding system without use of an external heat source comprises a two-piece structure broadly including a structural outer body for coupling the nozzle to a resin manifold and a thermally conductive insert. At least a portion of an axial length of the insert has an outer diameter that is less than an inner diameter of a coinciding coaxial portion of the outer body, such that the differences in the inner and outer diameters present an insulating air gap along at least a portion of the nozzle length. A sufficient operating temperature for hot melt resin can then be obtained without use of the external heat source.

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.

Abstract: A multi-container system having an outer container and an inner container. The outer container may at least partly define a hole extending entirely though the outer container, with the outer container at least partly surrounds the hole. The inner container may fit into and be received by the hole. The multi-container system may be shiftable between an assembled configuration, where the inner container is received and held within the hole, and a disassembled configuration, where the inner and outer containers are decoupled and separated from one another.
