Stopper characterized by comprising a hollow body, elastic material and cylindrical general shape closed by a base and open by the opposite, through which is fixed to a rigid support, d flattened, inside of which body is located accommodated with a rigid core, which is actuated by means of a rod, protruding to the outside and capable of being forced to move axially with respect to the assembly, determining the elastic deformation of the expressed body, with consequent increase in length and decrease in diameter of the same, which facilitates its introduction into the neck to be sealed, up to the limit position defined by the support, and determines a hermetic seal of this neck, when the whole is left to itself, thanks to the elastic tendency of the expressed body to recover its initial conformation.
