<p>A sheet (31) has a number of slots (32) laterally defining elements (33) with fold lines (34, 35) extending between said slots. One end of the sheet is attached to the bottom surface (11) of a box (10) and the other end is attached to the inner surface (21) of a lid (20) hinged to the box. The elements (33) can be spatially unfolded, forming at least one plane (36) parallel to one of the said surfaces (for example 21) when it is substantially perpendicular to the other surface (for example 11), and so that the scenery construction (30) is folded on itself when the lid is swung down on the box.</p> |
