Improvements in the truncated cone closing systems for boxes, which are characterized by the internal points of the horizontal diameter of the spherical bead placed on the edge of the lid, constitute a diameter smaller than the largest of the base of a truncated cone established by the upper part of the body of the box, so that said bead makes an elastic coupling in the inverted conical strip that extends inwardly from said larger diameter of the truncated cone integral with the edge of the box; the opening requires the use of lever elements of any type, which will act between the body of the box and the edge of the cover, in order to provoke with the lever or opener, a small transitory dilation so that at the point of opening it rises said bead on the largest frustoconical diameter of the box.
