New inviolable closure, characterized by the fact that it is constituted by a body of material that is sensibly flexible, such as the polyethylene piece that has an internal duct that, in its lower part, is cylindrical and extends in a conical shape that constitutes the upper one; existing in the external part of said zones, an inverted conical trunk section; an annular groove, a flange and a three step step, in which groove a flanging of the neck edge of the container is housed; with which this is pinched, under pressure by the wallet that prevents the introduction too much, of the closure, and the lower edge of the throat that does not allow the extraction of the closure, producing the opening of the closure, only at will, when the the last section of the staircase and then the communication between the interior of the continent and the exterior is placed; plugging the open conduit, with a cap that plugs into the intermediate step.
