The box (1) has an inner frame (2) movable at a base in which stretched sheets (7, 8) are fixed. An envelope (3) is provided for receiving the inner frame, and a hinge (10) connects the inner frame to the envelope. The hinge allows tilting movement of the inner frame relative to a housing, where the tilting movement successively combines a phase of vertical translation and a phase of rotation around a horizontal rotation axis (9). The horizontal rotation axis is eccentric with respect to the inner frame. |
