Abstract
A container formed from an integral piece of corrugated material includes projections extending from its upper side edges, and notches disposed on its lower side edges. The projections of one container are placed and sized to engage the notches of a similar container so that the containers engage when stacked. The engagement of the sides is such that the containers are unlikely to be inadvertently horizontally displaced, and have increased vertical weight bearing strength. The containers are apt for shipping and display cartons stacked on pallets accessed directly by end-user customers. The containers have four-layer sides to further bear vertical forces, to resist inadvertent collapse of the container or a stack of containers, and to increase horizontal rigidity.
