Abstract
There is provided a system, a method and preform suitable for executing liquid forming of the preform into a final-shaped container. The present technology includes various improvements to methods, apparatuses, and systems for forming final-shaped containers from preforms using a liquid destined to be contained in the final-shaped container.
Claims14
A method of simultaneously forming and filling a final-shaped container from a preform using a liquid, the liquid being a product to be contained in the final-shaped container, the method comprising:
- locating the preform in a mold cavity having an internal surface;
- sealably connecting a nozzle onto an opening of the preform;
- inserting a stretch rod through the nozzle into the opening of the preform, at least a lower portion of the stretch rod sealably connecting with an interior surface of the preform to at least partially isolate a gate portion;
- and
- stretching the preform into conformity with the internal surface of the mold cavity by:
- filling an interior of the preform with the liquid through the nozzle, and
- extending the stretch rod farther into the gate portion.
