Abstract

The invention relates to a double cartridge (1), a mixer (3) and a combination consisting of a double cartridge having a mixer. The cartridge has a guiding channel (14b) that is formed between protrusions (14, 14a; 1a). The mixer (3) has at least one guiding rib (13) to guide the mixer (3) in the double cartridge (1).

Claims

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, whose longitudinal axes extend parallel and on whose outer casing surface at least one protrusion is located respectively,

and 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 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 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 the width of the guiding channel that is formed between the protrusions and the width of the at least one guiding rib for guiding the mixer in the double cartridge, are adapted to each other.

2. The combination as recited in claim 1, 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.

3. The combination as recited in claim 1 wherein the width of the guiding rib is larger than the cross section of the opening of the largest outlet connection piece of the double cartridge.

4. The combination as recited in claim 1 wherein on the plate a guiding protrusion is formed that facilitates the insertion of the guiding rib into the guiding channel that is designed as a slot.

5. The combination as recited in claim 4 wherein the guiding protrusion has two facing tapered sections that are provided on both sides of the guiding channel and which are connected by a curved section.

6. The combination as recited in claim 4 wherein the plate has ribs that are opposite to the guiding channel.

7. The mixer for use in a combination as recited in claim 1 having a housing that defines a mixing chamber, whereby at one outlet opening of the housing, an outlet opening is provided and at its diametrically opposite inlet end of the mixer two inlet connection pieces discharging into the mixing chamber are provided whose longitudinal axes extent parallel,

wherein at the inlet end, 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.

8. The mixer as recited in claim 7, wherein the outer thread formed by several non-overlapping threaded bar segments.

9. The mixer as recited in claim 7, wherein the lengths of the inlet connection pieces are shorter in a direction facing away from the outlet end than the length of the at least one guiding rib.

10. The mixer as recited in claim 7, wherein the inlet connection pieces and the at least one guiding rib are components of a coupling section of the mixer that is housed freely rotatable in a mixer housing.

11. The mixer as recited in claim 7 with a drivable mixer spindle that has a hexagonal recess contour for the torque-proof housing of a drive shaft, wherein the mixer spindle is provided with an annular phase and/or triangles transitioning into the hexagonal recess contour at the inlet end.

12. The mixer as recited in claim 7, wherein the inlet connection pieces discharge in offset planes into the mixing chamber that is formed in the mixer housing.

13. The mixer as recited in claim 12 with a drivable mixer spindle, wherein the two planes at which the masses enter are separated by a disk on the mixer spindle, whereby openings permit the penetration of the mass entering through one of the inlet connection pieces.

14. The mixer as recited in claim 13, wherein ribs are provided in the spaces between openings.

15. The mixer as recited in claim 7 with a drivable mixer spindle,

wherein an annular space is formed in the interior of mixer that surrounds the mixer spindle in which the mass entering through one of the inlet connection pieces can be captured before it reaches into the mixing chamber.
