CONTAINER BASE WITH STRAPS AND DIAPHRAGM

A polymeric container including a base that moves inward toward the finish from an as-blown configuration to a post-fill, post vacuum configuration after the container has been filled and capped to generate a vacuum therein. In the as-blown configuration a diaphragm is linear in cross-section. In th...

Zusammenfassung:A polymeric container including a base that moves inward toward the finish from an as-blown configuration to a post-fill, post vacuum configuration after the container has been filled and capped to generate a vacuum therein. In the as-blown configuration a diaphragm is linear in cross-section. In the post-fill, post-vacuum configuration the diaphragm is concave relative to an outer surface of the base. As the base moves inward from the as-blown configuration to the post-fill, post vacuum configuration, an angle of intersection between an outer standing surface and a heel decreases as vacuum in the container increases and a pushup portion moves inward towards a finish of the container.
