A five-piece open container consists of a bottom piece and opposite side and end pieces which are pivotally mounted to the bottom piece so that they can be moved between an inwardly folded position and an erected position. A post is provided at each corner of the bottom piece and includes a locking member on its top wall which is engagedly received in a cavity provided at each corner of the underside of a similarly constructed container so that, when the side and end pieces are inwardly folded over the bottom piece, a stack of similarly constructed containers may be secured on top of one another.
