The bottle seal has outpouring section, in which, or at the flowing area adjacent to outpouring section, an oscillation producing device is fitted. The oscillation device shifts the oscillations through the flowing fluid or produces self oscillations through overflowing liquid in the liquid. The frequency of the oscillations produced through the element, in the fluid is in hearing range. Bottle seal has lower seal part (10) for fastening the seal to a bottle within the range of a bottle opening, discharge section (13,12,19) and a sealing plug (18) which releases or locks discharge cross section. |
