An improved stopper screw closure for bottles, made of plastic material, essentially characterized by the fact that it is formed by an external capsular lining provided on its internal part with a centered projection of frustoconical shape capable of exerting a compression action on the inner part of the neck of the bottle, which results in the tight fitting of the cap on the inside of the mouth of the container to be the same screwed to the neck itself.
