Stopper for bottles, characterized in that it is constituted by a cylinder of small diameter, which has a drill hole in its axis, and concentric with it is located at one end a flat disk that rests on the neck of the bottle to cover, and distributed along the axis of the plug three concave rings, whose concavity looks at the flat disk and whose diameter is slightly higher than the neck of the bottle to be used, for its perfect fit, the disc of the lower part being thicker to provide greater resistance ; along the axis and after this more resistant ring, two other small diameter concave rings are placed, which serve for guiding during the introduction of the cap into the bottle.
