The tops of the walls are outwardly surrounded by a horizontal rim (5) which is rectangular in shape and they are capped by a vertical rib (6) extending above the rim (5). The container has a cover (2) having a horizontal rim (8) and a vertical rib (9) extending downwardly therefrom suitable for engaging around the vertical rib (6) of the container (1). The vertical ribs (6, 9) being of substantially the same height on the container (1) and the cover (2). The vertical rib (6) on the container (1) is provided with notches (12) on at least two sides thereof, and the vertical rib (9) of the cover is provided with outwardly offset lengths (16) of reduced height disposed opposite the notches (12) in one position of the cover ( 2) and not disposed opposite the notches (12) in a second position of the cover (2).
