Base includes an outer support wall, a support surface extending inwardly from the outer support wall and defining a reference plane, an inner support wall extending upwardly from the support surface, a first radiused portion extending radially inward from the inner support wall and concave relative to the reference plane, a second radiused portion extending radially inward from the first radiused portion and convex relative to the reference plane, an intermediate surface extending radially inward from the second radiused portion, the intermediate surface including a linear portion and an intermediate radiused portion, a third radiused portion extending radially inward from the intermediate surface and convex relative to the reference plane, and a central portion disposed proximate the third radiused portion.

Variable displacement container base

Container having a body portion with sidewall defining outer perimeter and hollow interior. The body portion includes a plurality of continuous ribs extending about the outer perimeter of the sidewall, each rib having alternating horizontal segments and branched segments. Each branched segment includes a top branch and bottom branch joined at either end to define a bounded area therebetween. The plurality of continuous ribs includes at least a first continuous rib and second continuous rib spaced vertically from the first continuous rib. A midpoint of each branched segment of the first continuous rib is aligned along a vertical axis with a midpoint of a corresponding horizontal segment of the second continuous rib, and a midpoint of each horizontal segment of the first continuous rib is aligned along a vertical axis with a midpoint of a corresponding branched segment of the second continuous rib.
