Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A forming and filling head for simultaneously forming and filling a polymeric container with liquid, the forming and filling head comprising: a nozzle shaft assembly including a first portion removably engaged with a second portion, the nozzle shaft assembly defines a through-bore extending through each of the first portion and the second portion; an annular seal within the through-bore and 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; and flow ports defined by a wall of the nozzle shaft assembly, the flow ports extending 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; wherein the first portion and the second portion are threadably engagable with one another; and wherein the second portion is a nozzle shaft sleeve removably seated in the through-bore, the annular seal is seated on the nozzle shaft sleeve. 2. The forming and filling head of claim 1 , wherein the nozzle shaft sleeve defines a sleeve through-bore through which a nozzle shaft of the forming and filling head extends. 3. The forming and filling head of claim 1 , further comprising a nozzle sleeve that is connected to a nozzle and is vertically movable to open and close an outlet of the forming and filling head. 4. The forming and filling head of claim 1 , wherein the seal is seated in a seal groove defined by one of the first portion and the second portion. 5. The forming and filling head of claim 1 , wherein the polymeric container is a polyethylene terephthalate container. 6. The forming and filling head of claim 1 , wherein the liquid includes water, a beverage, or food. 7. A forming and filling head for simultaneously forming and filling a polymeric container with liquid, the forming and filling head comprising: a nozzle shaft assembly defining a through-bore and flow ports extending from an exterior of the nozzle shaft assembly to the through-bore to direct liquid into the through-bore; a nozzle shaft sleeve removably seated within the through-bore, the nozzle shaft sleeve defining a sleeve bore and including an annular seal extending around an interior of the sleeve bore; a nozzle sleeve seated within the sleeve bore, the annular seal seals against the nozzle sleeve; and a nozzle coupled to the nozzle sleeve, the nozzle is vertically movable by the nozzle sleeve to open and close an outlet of the forming and filling head through which liquid for forming and filling the container flows. 8. The forming and filling head of claim 7 , wherein the seal is seated in a seal groove defined by the nozzle shaft sleeve. 9. The forming and filling head of claim 7 , wherein the polymeric container is a polyethylene terephthalate container. 10. The forming and filling head of claim 7 , wherein the liquid includes water, a beverage, or food.
