ABSTRACT:
A collapsible container is formed from a blank of foldable sheet material. The container includes a plurality of upright first wall panels, second wall panels, and corner panels foldably connected to and disposed between a first wall panel and a second wall panel. The first wall panels, second wall panels and corner panels act together to define a predetermined area. Bottom forming side flaps are foldably connected to the bottom edges of the first wall panels and extend therefrom towards one another into the predetermined area, wherein the side flaps extend laterally beyond the first wall panels. Bottom forming end flaps are foldably connected to the bottom edges of the second wall panels and extend therefrom towards one another into the predetermined area. Portions of the end flaps overlie portions of the side flaps when both the end flaps and the side flaps are respectively extending towards the predetermined area. Each end flap is divided into an inner and outer portion by a fold line with notches being aligned and oppositely disposed on either side of the end flaps with said fold line and being configured to allow a portion of the end flap defined by the fold line to fit between the side flap. The outer portion of each end flap forms a locking element that fits between the side flaps when the outer portion is bent along the fold line relative to the inner portion and the side flaps are inserted into the notches.
