The drawer consists of a rectangular base (4) and four sides (6). The top edge (8) of the sides is wide and the outside corner of the edge, is integral with a flap (10). The width of the flap is the same as the depth of the drawer. The flap is furnished with a groove which runs longitudinally along the depth of the drawer. The depth of the groove coincides with the width of the top edge, so that when the flap is down the bottom of the groove rests on the side of the drawer. The bottom edge of the flap, of the same depth as the groove, hooks over a tab on bottom edge of the drawer. |
