摘要 |
A plastic container has a base adapted for vacuum pressure absorption. The base portion includes a chime extending from a body portion to a contact ring which defines a surface upon which the container is supported. The base further includes a central portion defined in at least part by a pushup having a generally truncated cone shape in cross section located on a longitudinal axis of the container, and an inversion ring having a generally S shaped geometry in cross section and hinge means formed therein, and circumscribing the pushup. The truncated cone has an overall general diameter that is at most 30% of an overall general diameter of the base and a top surface generally parallel to a support surface. |
