Abstract

Closure-seal for containers, of the type consisting of a hollow plug that is screwed onto the neck of the container and comprises a skirt joined by means of a weakened line, whose skirt and neck have mutual interlocking means for sealing and unsealed the container, characterized in that the skirt at its lower edge is provided with an internal flange capable of being applied selectively against the lower edge of at least two frustoconical annular projections surrounding the neck in respective sealing positions, the first of which corresponds to the application of the flange of the skirt against the upper shoulder of the neck in which a perforating punch provided in the bottom of the cap does not drill the mouth of the container, while in the lower position of the skirt perforation occurs, so that when the unscrewed from the plug, the flange of the skirt rests frictionally against the said shoulders to immobilize the skirt and determine the unsealing, by breaking the weakened line consisting of a line of climbing according to a transverse plane defining a projection and a notch facing each other and one of the pieces plug-skirt so that the projection is adjacent to one of the ends of the recess to allow the cap to be threaded upon sealing and to cause the tearing line to break, and thus the unsealing, when unscrewing the cap.
