Title:
METHOD AND APPARATUS FOR FORMING FINAL-SHAPED CONTAINERS USING LIQUID TO BE CONTAINED THEREIN
Document Type and Number:
WIPO Patent Application WO/2019/136551
Kind Code:
A1
Abstract:
A method, system, and preform for liquid forming of the preform into a final-shaped container using the liquid to be contained in the final-shaped container. The preform undergoes a stretching step to a size less than the size of a base of the final-shaped container, before being relocated and stretched to the final shape by the liquid. A stretch rod sealably connects with an interior surface of the preform to partially isolate a gate portion of the preform. The isolation is effected by a portion of the inner surface of the preform extending inwardly, or by a deformable member on the stretch rod which can selectively extend outwardly to contact the interior surface of the preform. The stretch rod includes a selectively heatable tip to heat the gate portion of the preform. The gate portion of the preform includes inner, outer, and core layers which comprise a material configured to affect the thermal properties of the gate portion.
