Abstract:
A composite stopper for stopping the neck of bottles of wine, comprising: a stopper body of generally cylindrical shape made from an elastically compressible material and having at least one circular flat end face, said stopper body having a circular cavity with a bottom formed concentrically in said end face, the diameter of the outer edge of said cavity being smaller than the diameter of the outer edge of said end face in the uncompressed condition of the stopper body such that a ring of said end face remains between the outer edge of said cavity and the outer edge of said end face; and a circular member made from an elastomer which is liquid impervious and which is elastically deformable but substantially incompressible, said circular member being fitted into said cavity such as to completely fill said cavity and to leave uncovered at least an outer portion of said ring of said end face of the stopper body, said cavity having such a volume that said member, upon radial compression to which the stopper body is subjected upon stopping, is elastically deformed forward of said end face, so as completely to cover said end face after stopping.
