Hot-fillable plastic container
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.
1. An asymmetrical hot fillable plastic container comprising:
a container body comprising a bottom portion, a sidewall portion and an upper portion, the container body having a chamber defined therein, the container body further comprising a finish portion extending from the upper portion and defining a mouth in fluid communication with the chamber;
the bottom portion including a support surface and a variable dynamic base portion extending inward from the support surface configured to deflect in response to a pressure differential between the chamber and an exterior of the container body;
the sidewall portion including a lower circumferential groove ring and an upper circumferential groove ring, wherein the lower circumferential groove ring has a width W 1 and a depth D 1 in side view, and an outer radius R 1 in plan view, a ratio of the width W 1 to the outer radius R 1 ranging between 0.07 to 0.22, and a ratio of the depth D 1 to the outer radius R 1 ranging between 0.04 to 0.18,
wherein the upper circumferential groove ring has a width W 2 and a depth D 2 in side view, and an outer radius R 2 in plan view, a ratio of the width W 2 to the outer radius R 2 ranging between 0.07 to 0.22, and a ratio of the depth D 2 to the outer radius R 2 ranging between 0.04 and 0.18, and
wherein the sidewall portion includes a plurality of vacuum panels, each vacuum panel configured to deflect in response to the pressure differential between the chamber and an exterior of the container body; and
a front sidewall segment of the sidewall portion has a front sidewall configuration, wherein the front sidewall configuration is different than a rear sidewall configuration of the sidewall portion.
2. An asymmetrical hot fillable plastic container comprising:
a container body comprising a bottom portion, a sidewall portion and an upper portion, the container body having a chamber defined therein, the container body further comprising a finish portion extending from the upper portion and defining a mouth in fluid communication with the chamber;
the sidewall portion including a lower circumferential groove ring and an upper circumferential groove ring, wherein the lower circumferential groove ring has a width W 1 and a depth D 1 in side view, and an outer radius R 1 in plan view, a ratio of the width W 1 to the outer radius R 1 ranging between 0.07 to 0.22, and a ratio of the depth D 1 to the outer radius R 1 ranging between 0.04 to 0.18,
wherein the upper circumferential groove ring has a width W 2 and a depth D 2 in side view, and an outer radius R 2 in plan view, a ratio of the width W 2 to the outer radius R 2 ranging between 0.07 to 0.22, and a ratio of the depth D 2 to the outer radius R 2 ranging between 0.04 to 0.18,
the sidewall portion further including a pair of longitudinal grooves extending longitudinally between the lower and upper circumferential groove rings to define a front sidewall segment on a front side of the sidewall portion between the upper and lower circumferential groove rings and a rear sidewall segment on a rear side of the sidewall portion between the upper and lower circumferential groove rings,
wherein the rear sidewall segment includes a plurality of vacuum panels and a rigid longitudinal support between two of the vacuum panels, each vacuum panel configured to deflect in response to a pressure differential between the chamber and an exterior of the container body; and
wherein the front sidewall segment has a constant radius in plan view to define a front rigid panel free of vacuum panels.
