Abstract:
Methods and systems for simultaneously forming and filling a container from a preform with fluid, adjusting a fill point of the fluid, and removing air and/or foam from within the container. One of the methods includes injecting fluid from a fill source into the preform through a nozzle passage defined between the nozzle and a seal pin of the forming and filling system to simultaneously form the container from the preform and fill the container. After the container is formed and filled, the seal pin is actuated to close the nozzle passage and prevent fluid and air from exiting the container through the nozzle passage, thereby trapping fluid and air within the container under pressure. Air, fluid, and/or foam is extracted out from within the container through a passageway defined within a stretch rod to adjust a fill point of the container.
