In a method for producing a composite capsule, a liquid or pasty substance, in particular a dental composition, is introduced into a receiving space of a capsule part. The receiving space is surrounded by a capsule wall, which has a discharge opening. A plunger is introduced into the receiving space and a capsule extension leads up to the capsule part. A connection is established between the capsule part and the capsule extension. With a corresponding composite capsule, it becomes possible to dispense an increased volume of the substance from the composite capsule.
