In the inclined position, the stopper 1 opens the neck 17 of the container shown in Figure 2B. The stopper 1 is held in this position by the protrusion 4a formed on the bottom 5 of the threaded stopper 2, the stopper 2 being assembled with the stopper 1 in a known manner using tubular elements 13 and 14 provided with circular ribs 15 and 16. The inclination of the stopper 1 held by the protrusion 4a is smaller than the inclination produced in the diametrically opposite direction and held by the protrusion 4b which is longer than the protrusion 4a. <IMAGE>
