"PERFECTED PLUG", which is characterized by being constituted by a body attached to the container that contains the liquid, but which, in any case, has a perforation in its upper part that communicates with another of smaller diameter that closes the container and on which supports an elastic element, special spring or thick-walled rubber tube, which at the other end supports a ball that, contained by a narrowing in the mouth, closes this, thanks to the pressure of said elastic element, or opens it leaving step to the liquid, when on it is pressed, overcoming the elastic tension.
