Liquid or hydraulic blow molding

A method of simultaneously forming and filling a container comprising:

• locating a preform in a mold cavity having an internal surface;
• sealably connecting a blow nozzle onto an opening of the preform;
• accumulating liquid into a chamber;
• sterilizing the preform prior to delivering the liquid into the preform;
• and
• mechanically actuating a member thereby delivering the liquid from the chamber, through the blow nozzle into the opening of the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container, wherein the liquid remains within the container as an end product.

• and
• wherein delivering the liquid from the chamber includes transferring the liquid into the preform at a first pressure and subsequently transferring the liquid into the preform at a second pressure, the second pressure being greater than the first pressure, the first pressure and the second pressure being between approximately 100 PSI and 600 PSI.
