<p>The invention falls within the sector of stoppers for opened bottles. An external body (1) is provided with an upper opening (4) designed to allow rotation of a lever (8) having an eccentricity (9). Operation of the said lever allows, by means of the intervening arrangement of a cylindrical helical spring (22), lowering of an internal body (16) against a toroidal spring (15). Radial deformation thereof allows gripping of the neck of the bottle underneath its shoulder.</p> |
