Stackable container having support flanges

Support surfaces useable on containers to permit stacking of said containers one atop another without nesting, said containers comprising a plurality of interconnected panels forming sidewalls surrounding a central space, said sidewalls having flaps extending therefrom and foldable to form a bottom, a first and a second of said sidewalls facing one another in opposing relationship, said support surfaces comprising:

• first and second support flanges respectively attached to said first and second sidewalls and extending lengthwise along edges thereof in spaced relation to said bottom, said support flanges each being oriented substantially at a right angle to said first and second sidewalls and projecting inwardly toward said central space;
• and
• side flanges attached to each end of said first and second support flanges, each said side flange also being attached to a respective sidewall adjacent to one of said first and second sidewalls, said side flanges each being folded along a respective fold line extending diagonally across each said side flange, said fold line dividing each of said side flanges into overlying flange portions, each of said overlying flange portions having an outer face, said outer faces of overlying flange portions being attached to one another in face to face relationship.
