Abstract: A plastic container that is adapted for adjustment to internal volumetric changes such as those that typically occur during the hot fill process includes a container body defining an internal space. The container body has a sidewall that is shaped to define at least one flexible panel. The flexible panel has a central longitudinal axis, an upper portion, a lower portion and a central portion. The central portion of the flexible panel has a width that is greater than a respective width of at least one of the upper and lower portions. The flexible panel is substantially flat as viewed in a longitudinal cross-section taken along the central longitudinal axis. Additionally, the central portion has a transverse radius of curvature that is greater than a transverse radius of curvature of at least one of the upper portion and said lower portion. Because the central portion represents the maximum width of the flexible panel, the efficiency of vacuum uptake is maximized with respect to conventional vacuum panels that are substantially flat in longitudinal cross-section.

Abstract: Plastic container comprises a container body having a bottom portion, a sidewall portion and an upper portion, with a chamber defined therein. The bottom portion includes a support surface and a variable dynamic base portion. The sidewall portion includes a lower circumferential groove ring, an upper circumferential groove ring, and a pair of longitudinal grooves extending longitudinally therebetween to define a front sidewall segment and a rear sidewall segment. The rear sidewall segment comprises a waist groove extending circumferentially between the pair of longitudinal grooves to define an upper rear sidewall segment and a lower rear sidewall segment, wherein one of the upper rear sidewall segment or the lower rear sidewall segment includes two vacuum panels with a rigid longitudinal support therebetween.

Abstract: Hot-fillable plastic bottle including a finished portion, a body portion with at least one circumferential rib configured to resist radial distortion, and a base portion. The base portion comprises a base sidewall, a bottom support surface extending radially inward from the base sidewall and defining a reference plane, an inner support wall extending upwardly from the bottom support surface, and a diaphragm extending radially inward from the inner support wall. The diaphragm comprises an inner wall having an arcuate shape with a radius r1 and a central conical structure, where the diaphragm is in an initial as-formed position with the conical structure above the reference place. The diaphragm is configured to move from an initial as-formed position toward a second position when an internal pressure relative an external pressure exceeds a threshold value.

Abstract: A container (110) having an inverted active cage generally includes an enclosed base portion (120), a body portion (130) extending upwardly from the base portion, and a top portion (140) with a finish (150) extending upwardly from the body portion. The body portion further includes a central longitudinal axis (L), a periphery, a plurality of active surfaces (160), and a network of pillars (170). Unlike the prior art, each of the plurality of active surfaces is outwardly displaced with respect to the longitudinal axis, while each of the network of pillars is inwardly displaced with respect to the longitudinal axis. The plurality of active surfaces, together with the network of 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.
