Abstract

The invention relates to a two-component mixing capsule (1) for intake and for mixing of two, preferably powdered or preferably pasty or kneadable, particularly preferably dental, compositions with a capsule housing (2) having a discharge opening (3) at its front end (2.1), wherein the mixing capsule (1) comprises a first mixing chamber (5a) and a second mixing chamber (5b), wherein the two mixing chambers may be separated from each other for storage or for transport, by the first mixing chamber (5a) being rotated by a rotatably mounted handhold element whose rotation axis (Y) is approximately perpendicularly arranged to the longitudinal axis (Z) of the mixing capsule (1) into a first position in which the first mixing chamber (5a) is separated from mixing chamber (5b), preferably the central axes of the mixing chambers are arranged to each other by approximately 90°. By rotating the first mixing chamber (5a) into a second position in which the central axes of the first and second mixing chamber are substantially coaxially arranged, the two mixing chambers form a common mixing chamber (5a+5b), wherein the composition may be discharged after mixing by attaching a squeezing piston.
