Container having a stacking feature

Abstract

A container having enhanced wall integrity with a rotational element and a stacking feature is provided. The container includes a sidewall having an alignment structure formed along a height of the sidewall and an upper stacking shoulder formed above the alignment structure. The alignment structure is adapted for orienting the container with respect to a second container so that the alignment structures 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 upper stacking feature is formed into the sidewall of the container and includes a radially extending wall portion and an upwardly extending wall portion that together form a stacking corner. The stacking shoulder is provided above the alignment structure facilitates nesting of two containers when stacked together.
