1. A mixing device comprising:
a container for receiving mixing material, with an emptying opening being arranged in the bottom thereof, and
a closure cover for closing the emptying opening, wherein the closure cover comprises two closure cover portions which can be reciprocated relative to each other between a closed position in which the two closure cover portions are in contact with each other and together form the closure cover and an opened position in which the two closure cover portions are spaced from each other so that an opening is formed between the two closure cover portions for removal of the mixing material from the container,
wherein both closure cover portions can be pivoted about the same pivot axis to reciprocate them between the closed position and the opened position,
wherein the closure cover portions have an inner surface which, with the emptying opening closed, is arranged within the container, an outer surface which, with the emptying opening closed, is arranged outside the container, and an edge surface which, with the emptying opening closed, is arranged opposite an edge surface of the emptying opening, and the closure cover portions, the emptying opening and the pivot axis are of such a configuration and arrangement that a point arranged furthest away from the pivot axis on the inner surface or the edge surface of the closure cover portions describes a circle in the pivotal movement, and
wherein the closure cover portions are arranged within the circle and the edge surfaces of the emptying opening are arranged outside the circle.
