Abstract

A mixer capsule, especially for the production of dental materials, comprising a cartridge (10) that is closed on one end by a piston (12). The piston has a hemispherical recess (12) that forms a chamber and is closed off from the main chamber (18) of the cartridge (10) by means of a separating device (16). A body (20) that is provided in the initial state in the main chamber (18) is used to facilitate the mixing process and to penetrate the separating device (16) at the beginning of the process, whereby the main chamber (18) and the subsidiary chamber (17) form a single mixing area. At the end of the output process, the body (20) enters the hemispherical subsidiary chamber (17) and acts as a displacer.
