A new non-refillable cap, characterized in that it consists of a hygienic tape that has the form of a cylindrical cap internally threaded and that at its lower edge carries a groove in which a ring is resiliently housed in elastic material in such a way that the part that protrudes supports on the next piece producing perfect closure that prevents evaporation and fouling. A second piece of circular plant in its center has a neck threaded externally to which thread is referred the previous piece. This neck narrower than the diameter of the piece itself, has flute embouchure to force pouring by the edge in peak, so that they are automatically left: positioned for their best operation channels and system parts. Diametrically opposed to the position of the projecting edge of the embouchure, it has a hole made on the flat shoulders of the piece, which it crosses, thus conferring the plug of an inlet mouth to the air of replacement of the space that leaves the liquid free when leaving. The extreme edges of the shoulders of this piece are flanged down in a flared form, in whose housing cavity to the next piece. (Machine-translation by Google Translate, not legally binding)
