A container is disclosed having a plurality of interconnected panels forming sidewalls surrounding a central space. Flaps extend from lower sidewall edges and fold along fold lines to form a bottom. Support flanges are arranged along upper sidewall edges on oppositely facing sidewalls. The support flanges are oriented at right angles to the sidewalls and provide a support surface allowing the containers to be stacked one atop another without collapsing or nesting within each other. Each support flange is supported by a truss formed by a panel segment extending angularly from the support flange to a support panel biased against the sidewall to which the support flange is attached by a retaining flap extending from an inner sidewall layer. Locking tabs at the ends of each panel segment are received within recesses positioned in sidewall panels perpendicular to the support flanges. The container is transformed from a knockdown formed from a unitary blank.
