Patent number: 11839519Abstract: Disclosed is 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.Type: GrantFiled: May 28, 2018Date of Patent: December 12, 2023Assignee: KULZER GMBHInventors: Andrea Kemeny, Mike Kondziela, Ralf Suffel, Andreas Utterodt, Michael Eck, Raif Kocoglu, Markus Balkenhol
