1. A mixing capsule (1) comprising a housing in the form of a cylinder, wherein the mixing capsule has an applicator (2) at the top surface (15) of the cylinder and an auxiliary capsule (3) to receive a composition B in the region of the base surface of the cylinder being mounted displaceably in the direction of the longitudinal axis, the auxiliary capsule (3) being mounted displaceably in the direction of the longitudinal axis in a cylindrical inside pipe (4) and/or a mounting of the mixing capsule (1), the housing of the mixing capsule comprising an outer housing sleeve (5) and an inner housing sleeve (6) being mounted rotatably against each other and displaceably in a telescope-like manner into each other, the auxiliary capsule (3) and the cylindrical inside pipe (4) and/or the mounting taking a first partial volume of the internal volume of the mixing capsule (1) in a first position of the inner housing sleeve (6), the mixing capsule (1) having a second partial volume of the internal volume (9) to receive a composition A being independent from the auxiliary capsule (3) and the cylindrical inside pipe (4) and/or the mounting, the internal volume (9) of the cylinder being increased compared to the first position in a second position of the inner housing sleeve (6) after the outer housing sleeve (5) and the inner housing sleeve (6) being pushed apart in a telescope-like manner along the longitudinal axis, the increased internal volume (9) being adapted to receive composition B of the auxiliary capsule (3) besides composition A, composition A and composition B being mixable to composition C by moving the mixing capsule, composition C being ejectable via the applicator (2) when the outer housing sleeve (5) and the inner housing sleeve (6) being telescoped, the auxiliary capsule (3) having an ejection piston (8), the ejection piston (8) being adapted to convey composition B from the auxiliary capsule (3) into the second partial volume or the increased internal volume (9) when being pushed or turned, the cylindrical inside pipe (4) or the mounting being adapted to receive the auxiliary capsule (3), the inner housing sleeve (6) being mounted displaceably within the outer housing sleeve (5) along the longitudinal axis of the mixing capsule (1) and rotatably about the longitudinal axis of the mixing capsule (1), the cylindrical inside pipe (4) or the mounting being mounted displaceably within the inner housing sleeve (6) along the longitudinal axis of the mixing capsule (1), and a part of the outer housing sleeve (5) and a part of the inner housing sleeve (6) being lockable in a first position of the inner housing sleeve (6) after the outer housing sleeve (5) and the inner housing sleeve (6) being telescoped along the longitudinal axis and after being rotated about the longitudinal axis.
