This relates to a tray which is useful for many purposes and wherein the tray may be shipped in a knocked-down state and is readily erected by an ultimate user manually or automatically. The tray includes a base panel having upstanding side walls which are not connected at their remote ends to one another. The side walls remain in upstanding positions by means of a simple locking flap arrangement. In the original blank state, each side wall is defined along a respective edge of a base panel by an inner sidewall panel and outer sidewall panel, the two sidewall panels being connected together along a fold line and the inner sidewall panel being connected to the base panel along a fold line interrupted at regular intervals by C-shaped caddy cuts. The flat blank is partially erected by the manufacturer by folding the outer sidewall panels beneath the inner sidewall panels and gluing them together in face-to-face relation. This may be accomplished on conventional equipment and the thus folded blank is ready for shipment to the customer. When the side walls are to be erected, they are merely folded upwardly until the outer sidewall panels snap past the projecting locking flaps which were defined by the caddy cuts.
