ABSTRACT:
This relates to a bottom construction for a blow molded container wherein a central portion of the bottom is axially inwardly recessed and pushed in and where, in the forming of the central portion, there are two axially offset halves so as to define an upstanding rib. The rib sufficiently reinforces the recessed bottom portion against inversion even when the wall thickness of the bottle or container is reduced.
