Case, characterized essentially by the fact that it consists of a laminar body with a prismatic contour, equipped with two folding lines close and parallel to the edges, from which pairs of inclined and convergent folding lines depart, a pair corresponding to each face of the prismatic body and in each base of the same, whose lines determine a fold like a bellows that is maintained in the closed position by suitable means.
