Abstract: A container designed to stack with another container of identical construction at a plurality of different levels. The container is a full slide-on container, that is it can be stacked by sliding it horizontally over the full width of another container. A drawer or tray in the bottom of the container may be withdrawn by a horizontal sliding movement through the open front of the container.

Abstract: An open top container adapted to stack with another container of identical construction at any one of three different levels. The container has stacking feet near the bottom. It also has saddles at three different levels for supporting the feet of an upper container. The container in its preferred form also has guiding means to permit it to be slid over the top of a lower container into a stacked position either at the upper level or at an intermediate level.

Abstract: A closed container composed of identical separable parts each of one-piece plastic construction. Each part has a rectangular base, an upright rear wall, and upright side walls cut diagonally or on the bias. The top and front of each part is substantially open so that it may be used independently of the other part for display purposes. When one of the parts is turned end for end, superposed over the other part and lowered relative thereto, snap-type connectors engage to hold the two parts in assembled relation to form the closed container.

Abstract: An industrial load-carrying pallet comprising an integral sheet of material formed with strengthening ribs extending thereacross, three centrally disposed pedestals extending downwardly at the center line and generally W-shaped pedestals disposed adjacent the side extremities. Grooves extend downwardly from the upper surface and are disposed along the circumference of four circles for receiving the bottom rims of four drums. The pedestals have recesses therein disposed on the circumference of four circles whereby the pedestals may rest upon and engage the top rims of four drums. The area of the top surface within each circle for receiving the bottom rim of a drum is spherically concave. The side pedestals have spaced converging walls in a downward direction which are joined at the lower extremities by a bottom base. Empty pallets may be stacked by placing the pedestals within one another.

Abstract: A sequence of containers of equal width and rectangular form with flat horizontal bottoms and flat vertical sides and ends can be placed in sequence one directly above another to form a self-supporting stack of vertically expanded height. By reversing the sequence, the containers can be placed one directly above another to form a self-supporting nest of collapsed height. The individual containers are symmetrical in shape both longitudinally and laterally and, except for incremental differences in length, can be identical in construction. The end-to-end relationship of successive containers can be the same for both stacking and nesting or individual containers can be turned end-for-end at will for either stacking or nesting. The compressive strength of the end panels provides strong support for either stacked or nested containers through upper and lower integral abutments on the end panels which fit against the side panels of underlying containers, when nested, and overlying panels, when stacked.
