摘要

The device has a container opening arranged at an upper side of the device. A receiving chamber (9) is provided at the opening, and content of the chamber is carried into an internal space of a drinking container. A threaded part (6) is provided at an upper region of the device, and is formed with a lower covering surface or a lower threaded part (7) of the chamber. The chamber exhibits an additional opening at a lower region of the device. The content of the chamber is released into the internal space through the additional opening by a rotational operation. An independent claim is also included for a method for preparing a creatine-mixed drink from an aqueous solution and a preset amount of creatine powder.
