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