Abstract
A tote box system employs two sets of nesting boxes that are identical except for side wall height that provides different volumes and except for bottom configuration that prevents bottom damage when a tall container is nested within a short container. The bottom configuration is such that there are flat engaging horizontal surfaces supporting the tall box on the short box without substantial engagement between reinforcing channels or like slanted vertical portions of the bottom that would otherwise have a strong wedging action if they fully engaged, particularly with a large stack of nested boxes.
