Claim Text:
1. A combination consisting of a double cartridge having a mixer, whereby the double cartridge has two supply containers that respectively have an anterior end with an outlet connection piece, wherein the mixer has a housing that defines a mixing chamber, whereby at one outlet end of the housing an outlet opening, and at its diametrically opposite inlet end of the mixer two inlet connection pieces discharging into the mixing chamber are provided, whose longitudinal axes extend parallel, wherein the mixer has an outer helical thread and the double cartridge has an inner thread for mounting the mixer on the double cartridge, that the at least one protrusion is located in such a way that each of the protrusions jointly form a plate and that between the protrusions at least one guiding channel is formed that is defined by an opening in the plate and that extends parallel to the longitudinal axes of outlet connection pieces, that at the inlet end of the mixer at least one guiding rib is provided that extends parallel to the longitudinal axes of the inlet connection pieces, and that at the inlet end at least one interlocking element is formed as an outer thread for detachable mounting to a cartridge system and that the width of the guiding channel that is formed between protrusions and the width of the at least one guiding rib for guiding the mixer in the double cartridge, are adapted to each other, wherein the lengths of the inlet connection pieces, of the guiding rib and the outlet connection piece and the position of the protrusions are coordinated in such a way that when the mixer is mounted on the double cartridge, the guiding rib engages with the guiding channel that is formed between the protrusions, before the inlet connection pieces make contact with the outlet connection pieces.
