  • Publication number: 20120207873
    Abstract: A mold device for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity and a central exterior rod system moveably disposed within the mold cavity. The central exterior rod system is positionable between an extended position engagable with the preform and a retracted position spaced apart from the preform. The central exterior rod system maintains a central orientation of the preform during formation.

  • Publication number: 20120093965
    Abstract: An apparatus for forming a container comprising a housing and a rod apparatus disposed in the housing. The rod apparatus includes a rod for at least partially forming a container preform. The apparatus further includes a nozzle system disposed in the housing that is operably coupled with the rod apparatus. The nozzle system is positionable between a first position preventing pressurized fluid from being injected into the container preform and a second position permitting pressurized fluid to be injected into the container preform.

  • Publication number: 20110300249
    Abstract: An apparatus for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source includes an inlet and a piston-like device. The piston-like device is moveable in a first direction wherein liquid is drawn into the pressure source through the inlet and in a second direction wherein the liquid is urged toward the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and creating a resultant container. The liquid remains within the container as an end product.

  • Publication number: 20090202766
    Abstract: Accordingly, the present disclosure provides a container and method of making a container. In one example, a preform is disposed into a mold cavity having a base forming assembly. The base forming assembly includes a base insert and a movable ring insert. The preform is blown against the mold cavity to form a body defining a base portion. The movable ring insert is advanced into the base portion to form a thinned flex point in the base portion while keeping the base insert fixed. The container is hot-filled with a commodity. The commodity is allowed to cool causing a vacuum in the container that results in the upward movement or inversion of a central inset portion defined at the thinned flex point.

  • Patent number: 6767197
    Abstract: A blow molding machine for producing a biaxially oriented, heat set plastic container, including a blow mold; a high-pressure gas source; a high-temperature gas source; a fluid source; a mixer coupled to the high-temperature gas source and to the fluid source; a blow core assembly having an exhaust; and a controller coupled to the high-pressure gas source, to the, high-temperature gas source, and to the fluid source. The PET containers produced by the machine have an average sidewall crystallinity greater than about 30%, which allows the PET container to maintain its material integrity during any subsequent pasteurization or retort process of the contents in the PET container, and during shipment of the PET container.

  • Patent number: 6709624
    Abstract: A method and apparatus for stabilizing a blow molded plastic preform and container in a blow mold during a demolding operation. The blow mold has a first mold section, a second mold section, and a mandrel. The mandrel cooperates with a pair of spring loaded jaws slidingly coupled to one or both of the mold sections. With the mold sections in their fully open position, the mandrel with an attached preform and/or container travels into the blow mold. During the final stage of closing the mold sections, the jaws contact the finish and restrain the container. As the mold sections begin to open, the jaws prevent any movement of the container relative to the mandrel.

  • Patent number: 6485670
    Abstract: A method for producing a biaxially oriented, heat set plastic container, including the steps of providing a plastic preform within a mold cavity; expanding and stretching the plastic preform into conformity with the surfaces defining the mold cavity to form a biaxially oriented plastic container; inducing crystallinity in the plastic container by using convection heat transfer to heat a surface of the plastic container to a temperature of at least 120° C.; and removing the plastic container from the mold cavity. The PET containers produced by the method have an average sidewall crystallinity greater than about 30%, which allows the PET container to maintain its material integrity during any subsequent pasteurization or retort process of the contents in the PET container, and during shipment of the PET container.
