Claim 23:
24. A container comprising:
an interior bottom perimeter;
a top container edge;
a first sidewall section extending from the interior bottom perimeter to the top container edge, the first sidewall section having an exterior surface that is substantially smooth;
a second sidewall section extending from the interior bottom perimeter to the top container edge; and
two or more steps bisecting the first sidewall section and the second sidewall section, each of the two or more steps comprising:
a first step surface at least partially defined by a first internal edge and a first external edge, the first step surface being located at a first height;
a second step surface at least partially defined by a second internal edge and second external edge, the second step surface being located at a second height that is less than the first height, wherein (i) each of the first and second step surfaces extends from the first sidewall section to the second sidewall section and (ii) all heights are determined relative to a height of the interior bottom perimeter; and
one or more ribs extending vertically along an external surface of a corner of the container, wherein one of the one or more ribs extends vertically from a location above one of the first or second step surfaces to a lowermost height that is less than the corresponding height of the one of the first or second step surfaces such that the one of the one or more ribs comprises a corner rib overhang across the first external edge or the second external edge.
