In order to close the discharge flare of a sanitary sink, a plunger (1) lies with its lower end (3) inside the discharge flare (2) on an upper element (8) of a part (4) whose lower element (9) is secured inside the discharge flare (2). Both elements (8, 9) may be alternatively engaged by exercising a pressure in a closed position, in which they are nested into each other, or in an open position, in which they are as spaced apart as possible. |
