Improved packaging, of the type comprising a box body and a cover body, both circular and tinplate, essentially characterized in that the cover body has a radially slotted circumferential skirt, which defines a plurality of teeth bent at their free edge towards the end. Inside; because said lid has in its active closing position, sensitive convexity in its base directed towards the outside, whose convexity to the above-mentioned teeth adjusted by its edges under an annular rib encircling the lateral wall of the body of the box, said edges exerting a radial closing pressure, provided by the convexity tension of the lid; because said lid is capable of inverting its convexity when a manual pressure is exerted in the center thereof, which determines the simultaneous separation of the teeth with respect to the base of the annular rib of the box, allowing the opening of the container by natural separation of the lid body; and because the radial pressure exerted on diametrically opposed teeth of the cap when it is in the open position and placed on the mouth of the box, produces the inversion of its concavity, and consequently the closing of the container, when the simultaneous adjustment of the lower teeth of the annular nerve of the box body.
