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.
