Free blow container with a push up base

Abstract

An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity is includes a pressure source having 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 freely expand until an unopened end thereof contacts a platen. The platen forms a bottom in a resultant container. The liquid remains within the container as an end product.
