Abstract
A container having an inverted active cage generally includes an enclosed base portion, a body portion extending upwardly from the base portion, and a top portion with a finish extending upwardly from the body portion. The body portion further includes a central longitudinal axis, a periphery, a plurality of rigidified and non-active surfaces, and a network of pillars or channels. Unlike the prior art, each of the plurality of non-active surfaces is outwardly displaced with respect to the longitudinal axis, while each of the network of pillars or channels is inwardly displaced with respect to the longitudinal axis. The plurality of rigidified or non-active surfaces, together with the network of rigidified channels or pillars, are spaced about the periphery of the container in order to accommodate vacuum-induced volumetric shrinkage of the container resulting from a hot-filling, capping and cooling thereof.
