Abstract
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, means for maintaining a desired saturation of gas in solution in the first liquid, and a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure 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.
Claims17
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 heat transfer system cooling or heating at least one of a first liquid and said mold to maintain a desired saturation of gas in solution in said first liquid, said heat transfer system including a molding heat transfer system operably coupled to a filling head to cool or heat said filling head directly;
- a pressure source urging said first liquid toward the preform;
- and
- a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure 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.
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 heat transfer system cooling or heating at least one of a first liquid and said mold, said heat transfer system including a first heat exchanger operably coupled to a filling head for cooling or heating said first liquid and a second heat exchanger disposed between said first heat exchanger and said filling head;
- a pressure system exerting a pressure upon said first liquid to maintain a desired saturation of gas in solution in said first liquid;
- a pressure source urging said first liquid toward the preform;
- and
- a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure 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.

- a pressure source urging said first liquid toward the preform at a velocity sufficient to maintain a desired saturation of gas in solution in said first liquid;
- and
- a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure 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.
