Abstract

A container having enhanced wall integrity and a rotational element is provided that includes a sidewall having polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. The peaks include first and second faces sloping in opposite directions designed to direct corners of the first container's sidewall toward the interior valleys of the second container in order to orient the containers as they are stacked.
