摘要
Drinking bottle (100) with an automatic aeration device (200), wherein the drinking bottle (100) comprises an interior space (120) enclosed in a substantially liquid-tight manner by a cover (110) for receiving a beverage, the aeration device (200) having a channel (230) for introducing gas from an environment through the shell (110) into the interior (120), in gas-conducting contact with the environment. A duckbill valve (240) is arranged in the channel (230) in such a way that the duckbill valve (240) closes in a liquid-tight manner when an overpressure (P) is present at an inner opening (232) relative to an outer opening (231), the duckbill valve (240 ) allows a flow of gas from the outer opening (231) to the inner opening (232) when there is an overpressure (P) at the outer opening (231) relative to the inner opening (232). The invention also relates to an automatic ventilation device (200) and a method for producing it.
