The present disclosure includes a forming and filling head for simultaneously forming and filling a polymeric container with liquid. The forming and filling head includes a nozzle shaft assembly having a first portion removably engaged with a second portion. The nozzle shaft assembly defines a through-bore extending through each one of the first portion and the second portion. An annular seal is within the through-bore and is seated at one of the first portion and the second portion to permit access to the annular seal when the first portion and the second portion are disengaged. Flow ports are defined by a wall of the nozzle shaft assembly. The flow ports extend from an exterior of the nozzle shaft assembly to the through-bore to direct the liquid for forming and filling the polymeric container into the through-bore.
A portable module for a container forming and filling system. The portable module includes a control module, an operator interface, a pump, connectors, and a transport member. The pump is configured to pump liquid for forming the container and filling the container into a container forming and filling machine. The connectors are for connecting the portable module to the container forming and filling machine. The transport member is for moving the portable module.
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.
A filling cylinder assembly for a container forming and filling system that simultaneously forms and fills a container from a preform with fluid. The filling cylinder assembly includes a cylinder having an inner wall defining a cavity. A piston head is at a distal end of a piston rod. An insert is configured to be seated in the cavity to provide the cavity with a reduced volume such that with the insert seated within the cavity the cavity has a first volume, and without the insert seated in the cavity the cavity has a second volume that is greater than the first volume.
A method for forming and filling a container. The method includes: determining an effective fill area of an opening of the container through which fluid can pass while a stretch rod is seated within the opening; actuating a seal pin to open a nozzle passage of the nozzle to allow the fluid to flow through the nozzle passage and through the opening to simultaneously form and fill the container; detecting a degree to which the nozzle passage is open; increasing fill velocity of the fluid to the nozzle as the nozzle passage is opened; setting fill velocity of the fluid to a maximum fill velocity when the nozzle passage is opened such that an area of the nozzle passage is at least equal to the effective fill area at the opening of the finish; and closing the seal pin after the container is formed and filled.
