A collapsible container for packing, shipping and displaying articles is formed from an integral piece of corrugated craft, paperboard or similar foldable material. The container includes a plurality of panels which are connected to form a bottom, front, back and exterior sidewalls, and preferably also a top. A bellows fold connects each of the exterior sidewalls with at least one of the front and back walls. Each exterior sidewall is provided with a respective interior sidewall which together support a horizontal ledge. The horizontal ledges are useful for stacking multiple cartons in vertical alignment and can support containers that are somewhat out of registry. Locking tabs extend from the bellows panels of the container to limit lateral deflection of the sides and deformation of the container.
