Abstract
Abstract A container is provided preferably made of wax impregnated corrugated board, of nesting pyramidal shape. A locking member of U-shape is cut from the end wall, and extends inwardly through openings in the adjacent side wall flaps, and then downwardly when plural boxes are nesting. The locking member is pulled up to engage a tab on a depending flap extending downwardly from the top of the end wall. A top is provided, having holes therein, and holes are provided in the bottom: positioning tabs extend upwardly above the top to insure stacking of filled boxes with the holes aligned. A separate top is provided in one embodiment, with locking flaps in the end walls extending into hand receiving openings of the container to lock them together. In a second embodiment, the side walls each has a panel connected to its upper edge which depends into the container, with top flaps connected thereto and extending towards the opposite side wall.
