Abstract
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.
