Abstract
A capsule for mixing and dispensing a dental material which has a body forming a cavity. The cavity is closed by a liquid container. The body and the liquid container in combination form a mixing chamber containing a first component of the dental material. The liquid container has a cup-shaped cartridge formed by a cartridge front wall and a cartridge side wall and having a rear opening. A plug is movably joined within the cartridge through the rear opening for extruding a liquid second component of the dental material. The cartridge further has a channel extending through the cartridge side wall for releasing the second component into the mixing chamber. The body side wall inwardly has a recess being dimensioned for establishing a fluid communication between the channel and the cavity in an activated position, where the activated position corresponds to a second axial position of a two different axial positions of the of the cartridge and the body relative to each other. Further the first axial position corresponds to an inactivated position in which the channel is offset from the recess. A first cover film seals the joint between the cartridge and the plug, and the channel is openably sealed by a second cover film at least in the inactivated position. The capsule helps facilitating the preparation of a dental material.
