Notching the bottom to receive the end walls such that they grip the bottom prevents longitudinal relative movement of the stacked boxes.

Abstract: A bucket that children cannot put over their head, having a bottom wall, side walls, a removable lid and a non-pivoting U-shaped handle. The side walls project upwardly from the bottom wall and form an opening having circumscribing edges. The removable lid fits in the circumscribing edges for closing the bucket. The non-pivoting U-shaped handle has opposite side legs slidably mounted onto the side walls. The U-shaped handle also has stopping means for limiting sliding of the handle between a first position where the U-shaped handle bears against the lid when the same is fitted in the circumscribing edges and a second position where the U-shaped handle extends away from the lid and thus makes it possible to remove the lid from the circumscribing edges. Thus, the U-shaped handle, both in first and second positions, divides the opening into two smaller openings which are smaller than a child's head, thus children cannot put the bucket over their head.
