Abstract
A plastic container includes an upper portion having a mouth defining an opening into the container. A shoulder region extends from the upper portion. A sidewall portion extends from the shoulder region to a base portion. The base portion closes off an end of the container. The sidewall portion is defined in part by at least two vacuum panels formed therein. The vacuum panels are movable to accommodate vacuum forces generated within the container resulting from heating and cooling of its contents. The shoulder region and the base portion each define an interlocking structure suitable to achieve a nesting relationship with complementary mating surfaces of an adjacent container.
