Abstract: The invention relates to a drinking container with an interior space for receiving a liquid with a container opening that is arranged preferably at the top side, in which a mixing device is mounted, which consists of a movable wire element. The invention is characterized in that the wire element is embodied as a flat elastic spiral (3), which is mounted with one end on the drinking container (7) or the closure element thereof, while the other end of the spiral (3) ends freely in the container space. Thereby the spiral (3) is embodied so that it is freely swingingly movable at least in a linear direction in the container interior space due to a container motion and its self-weight.

Abstract: A closure apparatus is fitted onto a container opening of a drinking container with an inner space for reception of a drinking liquid. The closure apparatus includes a chamber body that defines therein a receiving chamber, the content of which is introducible into the inner space of the drinking container. The closure apparatus further includes a closure element that selectively closes a first opening of the chamber body, and an axially slidably displaceable cover element that selectively closes a second introduction opening of the chamber body. The content of the receiving chamber is releasable into the inner space of the drinking container through the second introduction opening by an axial sliding displacement of the cover element.

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.

Abstract: The invention relates to a closure apparatus for a drinking container with an inner space for the reception of a drinking liquid and a container opening which is preferably arranged on the upper side and in which the closure apparatus is provided with at least one receiving chamber (3), the content of which is introducible into the inner space of the drinking container. The invention is characterized in that, at least in the upper region the closure apparatus comprises a rigid upper closure element (1), which, with a lower axially slidably displaceable cover element (2), forms a receiving chamber (3), which comprises an introduction opening (18) at least in the lower region. The content of the receiving chamber (3) is releasable into the inner space of the drinking container through the introduction opening (18) by an axial sliding process.

Abstract: The invention relates to a drinking container with an interior space (5) for receiving a drinking liquid (14) and a container opening (4) preferably arranged on the top side, into which a closure device (3) with a receiving chamber (9) is provided, the content of which is introducible into the interior space (5). The invention is characterized in that the closure device (3) has an externally threaded part (6) at least in the upper area, which forms a receiving chamber (9) with a bottom cover surface (7) and connection elements (8) disposed therebetween, and the receiving chamber (9) has an introduction opening (22) at least in the bottom area. In that regard, the content of the receiving chamber (9) is releasable by a turning-in process. The drinking container preferably serves for the preparation of an unstable mixed drink of creatine powder (13) and an aqueous drinking solution (14).
