Abstract: A one-piece box blank which is formed of hingedly interconnected top, rear and bottom walls and end panels hingedly connected to the front and rear walls and adapted to interleave and interlock to form end walls of the box, has opposite ends of the bottom wall notched so that the bottom wall is shorter in length than the front and rear walls and is therefore adapted to nest in the top of a substantially identical box. Nesting is also facilitated by notches formed in the lower edges of the end walls and the fact that the upper edges of the end walls extend above the upper surface of the top wall. With this construction several containers can be stacked with the notched ends of the bottom wall received between the upper edges of the end walls, mechanically interlocking the boxes against end to end movement and providing substantial frictional resistance against side to side movement by virtue of the contacting surfaces of the stacked boxes.
