Two-component mixing capsule, particularly for highly viscous dental materials

A two-component mixing capsule for intake and for mixing of two compositions with a capsule housing having a discharge opening at its front end,

• wherein
• the two-component mixing capsule comprises a rotary element rotatably mounted in the capsule housing and a lid arranged opposite the rotary element in the capsule housing without a handhold or without handholds, a rotational axis of the rotary element being approximately perpendicularly arranged to a longitudinal axis of the mixing capsule, and a rotatably mounted first mixing chamber being assigned to the rotary element in the capsule housing, and a second mixing chamber being arranged in the capsule housing, a sealing piston being arranged at a back end of the capsule housing, and the sealing piston being passable through the first mixing chamber and the second mixing chamber along the longitudinal axis of the mixing capsule when the first mixing chamber is coaxially oriented with the longitudinal axis of the mixing capsule, the lid without handhold(s) is non-rotatably connected to the capsule housing, wherein
• a) a separate handhold element is attachable to the rotary element or lockable to the rotary element, or a separate handhold element or a squeezing piston is insertable into the rotary element in an opening,
• b) the rotary element has at least one groove,
• c) the rotary element has at least one handhold integrally connected to the rotary element, or
• d) the rotary element has at least a polygonal opening, an opening having one-fold or multi-fold symmetry to receive a polygonal profile, or at least one protrusion at a lateral periphery of the lid or at least one protrusion retractable into the lid or at least one protrusion foldable into the rotary element or at least one handhold element foldable into the rotary element.
