摘要

The opener (8) has an air supply chamber (10) with an air inlet opening (12) at a rear side of a base body and an air outlet opening (14) at a front side of a rear area, where the opener is made of metal or plastic. An air tearing edge (16) is formed at a side of a passage opening (DU) of a resonance cavity such that different whistler sounds are produced by air flow from the outlet opening during opening of a bottle and/or by a mouth opening that is partially covered by a lower side of the base body, where the side is arranged opposite to the outlet opening.
