<p>In order to seal a spray cap acoustically, a cap (7) with a button (6) is provided with a seal (49) between the button (6) and the cap (7) so as to form an acoustic seal (49) of the cap (7). The seal (49) consists of a sealing lip (8) at the edge of the cap (7) and of a further sealing lip (9) at the edge of the button (6). The two sealing lips (8, 9) are oriented horizontally. The sealing lip (9) of the button (6) lies on the sealing lip (8) of the cap (7) when the button (6) is not actuated. Upon appropriate actuation of the button, the sealing lips (8, 9) are tensioned and, when their tension is subsequently released, they support a return pivoting movement of the button (6) to its uppermost position.</p> |
