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.
