Patent ID: 7370775

Claim:
A container base comprising: an annular bearing surface defining a bearing plane; a parting line extending along the base defining first and second portions on opposite sides of the parting line; an inner portion spaced from the bearing plane and surrounded by the annular bearing surface, first and second lugs extending outwardly from the inner portion towards the bearing plane without intersecting the bearing plane, the first lug defining a first end surface, and the second lug defining a second end surface, wherein the first portion and the second portion are offset from one another to form a common offset wall extending through the inner portion and including the first end surface and the second end surface, wherein the common offset wall comprises a vertical surface extending along the parting line, the vertical surface being substantially perpendicular to the inner portion and having a substantially uniform height between the first end surface and the second end surface, said offset wall providing resistance to distortion upon an increase of internal pressure within the container.
