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.
