Abstract
An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold having a mold cavity defines an internal surface and is adapted to accept a preform. A pressure source is operable to draw liquid through the inlet and urge it into 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 create a resultant container. A pressure compensation system can exert a clamping force on the mold in response to the pressure source. The liquid remains within the container as an end product.
Claims20
A system for simultaneously forming and filling a container comprising:
- a mold having a mold cavity defining an internal surface and adapted to accept a preform;
- a pressure source urging a first liquid toward the preform;
- a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure or volume into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container, wherein the first liquid remains within the container as an end product;
- and
- a pressure compensation system exerting a clamping force on said mold in response to said pressure source.
