NEW MODEL OF CLOSURE PLUG FOR METAL CONTAINERS, characterized in that it is constituted essentially by a threaded flange that is placed in an inverted position, fitting it into the bas-relief produced by die-cutting in the drum plate, said flange being held externally by the cap that is it screws in it, as well as by a washer that holds it inside by means of electric spot welding, taking advantage of said welding to externally hold the holder part to which the capsule of the seal itself is attached and sealed.
