The lid (2) in the closed position rests on projection (6) arranged on frame (3) inside. The hinge arrangement can be turned around a part of its outer edge or inside to an open unstable position, in which position it has to be retained so that it does not, under the influence of forces of gravity, return to its closed position. The arrangement comprises at least one hinge (9) with two rectangular arms (19,11) located on each short side around a common axis. A first arm is movable across the axis between two end positions in a track issuing on the underside of the lid. The other arm is movable from a stop position across the axis in a track issuing in the body opening and arranged on the frame wall inside. The hinge with its other arm (11) in the stop position restricts the lid opening to the unstable position. |
