ABSTRACT:
A blank of sheet material for forming a container including automatically locking bottom panels is provided. The blank includes a pair of end panels, a pair of side panels and at least one corner panel that are interconnected. The corner panel extends between an adjacent end panel and side panel. The blank includes bottom end panels extending from the end panels and bottom side panels extending from the side panels. A first coupling tab is integral with a bottom end panel, and a second coupling tab is integral with a bottom side panel. The first coupling tab attaches to a bottom side panel, and the second coupling tab attaches to a bottom end panel. The coupling tabs upwardly direct the bottom panels when the container is moved to a flat position and downwardly direct the bottom panels when the container is moved from the flat position to an erected position.
