AbstractAn interlock is disclosed for stackable lower and upper boxes. The lower box is provided with upstanding hook-shaped tabs extending upwardly from parallel walls and the upper box is provided with slots in the bottom which register with the tabs when the upper box is laterally offset from the lower box. After the tabs are inserted into the slots, the boxes are shifted laterally into alignment with each other and the hook-shaped tabs overlap the bottom of the upper box. Box blanks are disclosed for making the upper and lower boxes with the interlock tabs positioned so that the box blanks can be nested for saving material. A corner interlock is disclosed for latching the interlock tab in the locked position.
