Abstract: A cartridge for storing and applying a mass, especially a mass of dental material, includes a tube-shaped base body having a first cylindrical portion and a second bent portion and an extrusion spout. A load engaging element cooperates with an extrusion drive device that can be activated to perform an extrusion operation in which the mass in the cartridge is extruded from the extrusion spout. The cartridge also includes an axially displaceable piston disposed in the base body and operable to be displaced by operation of the extrusion drive device such that the piston, as it moves relatively within the first cylindrical portion and the second bent portion of the base body, pushes the mass out of the base body into the extrusion spout and therebeyond. The inner diameter of the extrusion spout is smaller than the inner diameter of the base body and the piston is at least partially bendable.
