ABSTRACT:
A folding box having a body with two opposite sides being provided with folding lines (a, b, a', b'), which enable folding this body down flat. The body is combined with a stiffener, the central part (2, 3, 4) of which is adapted so as also to fold down flat on the folded box body. The stiffener has a contour corresponding to that of the bottom of this body so as to match this contour when the stiffener is unfolded in the box body. This folding is applicable to boxes known as "boutique boxes" having a rigid nestable lid.
