An improved stopper for barrels, consisting of a metal ring with a frusto-conical shape, externally threaded for wood and internally with a screw with a blunt profile; in which for the latter screw has threaded another metal ring of general external form of plug, but terminated by its lower part in a rim in which a crown cap is applied and fastened, and the upper part is provided externally with a thread of screw with a blunt profile. The plug-shaped metal ring also has an annular recess on top of its head, a cylindrical or frustoconical hollow, another cylindrical hollow of smaller diameter (both hollows have the same axis) and two or more notches on the upper part of the greater hole. You can complete this device in a cork stopper inserted in the smaller hole of the cap-shaped ring, and a marked disc to be placed in the annular recess or a seal made with sealing or other suitable material.
