Abstract:
A system for pre-stretching a preform utilized in forming a container. The system including an oven, a conveyor system configured for transporting preforms through the oven a blow molding station having at least one mold with interior surfaces defining the shape of the container, and a transfer station configured to transfer a preform from the oven into the blow molding station. The system also includes a stretch rod and an actuator. The stretch rod is movable between retracted and extended positions such that, when in the extended position, the stretch rod is positioned interiorly of the preform and the preform is elongated by the stretch rod to form a pre-stretched preform. The stretch rod is located to form the pre-stretched preform prior to the blowing medium being introduced into the preform in the blow molding station.
Abstract:
A system for simultaneously forming and filling a container having a mold cavity defining an internal surface and adapted to accept a preform. The system includes a servo pressure system having an inlet and an outlet operable to output fluid, such as a liquid commodity, and a blow nozzle receiving the fluid from the servo pressure source and transferring the fluid at a pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and creating a resultant container, wherein the fluid remains within the container as an end product and wherein the servo pressure system and the blow nozzle output the fluid at a rate sufficient to fully form and fill the container in less than about 0.5 seconds.
Abstract:
A system for forming a container from a preform includes a first mold operable to receive the preform and operable to blow mold a first form of the container from the preform. The system also includes a second mold operable to receive the first form and operable to blow mold a second form of the container from the first form. The preform, the first form, and the second form each include a substantially common transitional wall. Also, the first form can include various features that ensure that material will be distributed as desired throughout the container, to ensure high wall strength, and to ensure high crystallinity.
Abstract:
A mold for forming a plastic container having an integrally formed standing ring. The mold includes a first mold portion and a second mold portion. The second mold portion is movable relative to the first mold portion. The first mold portion and the second mold portion together define at least in part a mold cavity for molding a plastic container. The first mold portion and the second mold portion together define a standing ring slot for forming a standing ring on a base portion of the plastic container. The standing ring slot is defined at an interface between the first mold portion and the second mold portion.

Abstract:
A mold device and a method related thereto for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity, an optional stretch initiation rod system for engaging an interior portion of the preform to define a stretch initiation area, and a centrally disposed pressure source positionable within the preform for introducing a pressurized fluid.
Abstract:
A molding system for molding a container includes a first blow mold operable for blow molding a first form of the container and a second blow mold operable for blow molding a second form of the container. The system further includes a counter stretch rod and/or a base pushup operable for reducing a height of the first form of the container before blow molding the second form of the container. A corresponding method of forming a container is also disclosed.

Abstract:
A system for forming a container from a preform, wherein the preform has a finish and a support ring. The system includes a mold having a mold cavity defining an internal surface and adapted to accept the preform, a pressure system having an inlet and an outlet outputting fluid, a blow nozzle receiving the fluid from the pressure system and introducing the fluid at a pressure into the preform thereby expanding the preform toward the internal surface of the mold cavity and creating a resultant container. The system further includes a first seal engagement selectively engageable between the blow nozzle and the finish of the preform and a second seal engagement selectively engageable between the blow nozzle and an adjacent feature.
