Container having enhanced wall integrity and alignment element

A container comprising:

• a plurality of alignment structures, the plurality of alignment structures forming a generally frustoconical sidewall having an interior surface that conforms to an exterior surface;
• wherein each of the alignment structures extend radially outward relative to the sidewall in the direction of a longitudinal apex forming valleys along the longitudinal apex on the interior surface of the sidewall and peaks along the longitudinal apex on the exterior surface of the sidewall;
• wherein each alignment structure is circumferentially curved;
• and
• wherein the container is capable of being fully nested within a second identical container.

A container comprising:

• an upwardly-extending frustoconical sidewall comprising a plurality of alignment structures oriented relative to one another, the sidewall having an exterior surface and an interior surface that radially and axially conforms to the exterior surface;
• wherein the alignment structure includes a protrusion extending radially outward, forming a valley on the interior surface of the sidewall and a peak on the exterior surface of the sidewall;
• wherein each alignment structure includes an alignment ridge extending from the peak on the exterior surface of the sidewall;
• and
• wherein the substantially rigid container is capable of being fully nested within a second identical container.
