Abstract
A cartridge for containing material in paste form, having a cylindrical container unit, an outlet tip with an outlet passage disposed at one end of the container unit at an angle to its axis, a protective cap encasing the outlet tip, a mounting disposed at the second end of the cylindrical container unit, which is provided for mounting the cartridge in an ejector device, and a piston having a cylindrical circumferential surface and disposed for movement in the longitudinal direction of the cartridge which is provided for sealing off the cartridge interior as well as for dispensing the paste material. In order to attach the cartridge securely to an ejector device and assure a high standard of hygiene, the end of the outlet tip remote from the container unit, at which an outlet orifice is disposed, is at a radial distance from the axis of the container unit that is no more than exactly as great as the radius of the container unit. The mounting is configured as a screw thread and the protective cap as a cylinder closed at one end, whose inside diameter is at least just as great as the outside diameter of the container unit, the protective cap encasing the container unit.
