Abstract

A container having enhanced wall integrity is provided that includes a sidewall comprising at least one alignment structure formed therein or as a part thereof. The alignment structure is adapted for orienting the container with respect to a second container such that the containers become aligned or indexed such that they may be fully nested one within the other. The alignment structures can each include a protrusion that extends radially outwardly relative from the sidewall to form peaks along an external surface of the container and valleys along an inner surface of the container. Each alignment structure may further include an alignment ridge protruding from the peak of the alignment structure. Such alignment ridges may project outwardly from a remainder of the peak of the alignment structure at an angle, radius, or curvature that is different than that of the remainder of the peak.
