The disclosure relates to a two-component mixing capsule for intake and for mixing of two compositions with a capsule housing having a discharge spout at its front end, wherein the mixing capsule comprises a first mixing chamber and a second mixing chamber, wherein the two mixing chambers may be separated from each other for storage or for transport, by the first mixing chamber being rotatable into a first position in which the first mixing chamber is separated from mixing chamber, by a rotatably mounted handhold element, the rotational axis of which is approximately perpendicularly arranged to the longitudinal axis of the mixing capsule. The two mixing chambers form a common mixing chamber by rotating the first mixing chamber into a second position in which the central axes of the first and second mixing chamber are substantially coaxially arranged, wherein the composition may be discharged after mixing by attaching a squeezing piston.

Mixing capsules and methods are provide and comprise a first chamber to receive a composition A and a second chamber to receive a composition B, wherein the first chamber and the second chamber are arranged rotatably about the longitudinal axis of the mixing capsule, the first chamber comprising a first opening, the second chamber comprising a second opening, the first opening and the second opening being arranged perpendicularly to the longitudinal axis and plan-parallelly to each other and/or perpendicularly spaced, the first opening and the second opening being arranged incongruently to each other in a storage position, the first opening and the second opening being arranged congruently to each other in a handling position.
