Closure device for a drinking container

Abstract

The invention relates to a closure device ( 3 ) for a drinking container ( 1 ) with an interior space ( 10 ) for receiving a drinking liquid and a container opening preferably arranged on the top side, into which container opening the closure device ( 3 ) with a receiving chamber ( 4 ) is provided, the contents of which can be introduced into the interior space ( 10 ). The invention is characterized in that the closure device ( 3 ) has an externally threaded part ( 5 ) at least in the upper area, which, with a lower cover surface ( 6 ) and connection elements ( 8 ) lying therebetween, forms a receiving chamber ( 4 ) which at least in the bottom area comprises an introduction opening ( 14 ). Thereby the contents of the receiving chamber ( 4 ) is freely releasable by a turning-in process. The drinking container preferably serves for the preparation of an unstable mixed beverage of creatine powder and an aqueous drinking solution.
