VACUUM ABSORBING, BLOW MOLDED, CONTAINER BASE
20260021623 · 2026-01-22 ·

A container blow molded from a polymeric material, which is configured to store a hot-fill product. A first wall extends from a standing ring to a diaphragm of a base. A first hinge is at a first interface between the first wall and the standing ring. A second hinge is at a second interface between a second wall and a third wall extending to a center portion. In response to a vacuum generated within the container as the hot-fill product cools subsequent to filling and capping the container, the base is configured to move inward from an as-blown configuration to an activated configuration to absorb the vacuum by flexing at the first hinge and the second hinge. In the activated configuration, the center portion, the second wall, the third wall, and the second hinge are closer to the finish than in the as blown configuration.

Ionized nozzle

A blow molding station may include a mold configured to support the preform. A blow molding station may include a stretch rod configured to stretch the preform within the mold. A blow molding station may include a nozzle configured to direct pressurized gas into the preform. A blow molding station may include a high-voltage module configured to impart an electrostatic charge to the pressurized gas directed into the preform.
