  • the Axis of symmetry points in the direction of the tubular part.
  • the device according to the invention as well as the known devices are composed of components that are relatively inexpensive Plastic can be produced by injection molding.
  • the assembly of the Components that are advantageously carried out with the help of automatic machines should also be used as few steps as possible can be carried out to keep manufacturing costs low to be able to hold.
  • Compared to the known devices fall in the inventive device assembly steps away with a Rotational position of the transition piece with respect to the housing or the coupling means are connected.
  • the coupling means comprises a bayonet catch.
  • the transition piece is regarding this To keep a predetermined orientation.
  • a predetermined orientation with regard to the selected mixer structure required.
  • Rotational position in relation to the housing as well as the coupling means Transitional part can be used. So there are special measures and Process steps regarding the orientation of the transition piece away, such as they are required in the known devices. thanks to this Simplification reduces manufacturing costs.
  • the dependent claims 2 to 9 relate to advantageous Embodiments of the device according to the invention.
  • Subject of Claims 10 and 11 are uses of the device.
  • Figures 1 and 2 show an inventive device, the following Components include: a housing 1 which can be placed on a container 2 an outlet opening 12 at the tip for mixed components, wherein the housing 1 is a transition part 11 that can be coupled to the container 2 and a tubular part 10 between the transition part 11 and the outlet opening 12; a static mixer 4 which one in the tubular part 10th has insertable structure; a rotatable in the transition part 11 arranged transition piece 3, the separate feed channels 31, 31 'of Outlet openings 21, 21 'of the container 2 to the mixer structure 4 manufactures and that a flow of the components only through these feed channels 31, 31 '; and a coupling means 15; namely a screw thread 15 ', for releasably attaching the housing 1 to the container 2.
  • the in Fig. 3 shown container 2 which is a cartridge in the present example, comprises two chambers 20, 20 '(partition 24) for storing two mixing components and a connector 22 with an inner Screw thread 25 (not shown), which is the counterpart to the outside Screw thread 15 'of the coupling means 15 forms.
  • the transition piece 3 has a rotationally symmetrical outer contour. It is therefore with regard to the assembly in any rotational position Housing 1, the mixer structure 4 and the coupling means 15 in the Transitional part 11 can be used.
  • the transition piece 3 points to its positioning on the container 2 Means 32 with which a rotationally fixed position on the container 2nd can be produced.
  • These positioning means 32 exist in the example shown from parts that partially protrude from the transition part, namely one Rib with two marginal tines 32 '.
  • At the connector 22 of the Container 2 are arranged according to recesses 23, which to the Positioning means 32 of the transition piece 3 are complementary are. These recesses 23 can also be only partially complementary be trained.
  • Fig. 4 shows the area of the transition piece 11 of a second Embodiment in which the coupling means 15 separately on the Transition part 11 comprises applied part 6, which by means of a detachable Snap lock (6 ', 61, 26; 6 ") can be attached to the container 2.
  • the part 6 consists of a coupling ring 60 and two resilient legs 6 'and 6 ", which have feet 61 in corresponding recesses 26 of the container 2 are hookable.
  • the dash-dotted leg 6 lies in front of the Drawing level.
  • the transition piece 3 consists of an elastomer Material that - as shown in the drawing - corresponds to one
  • the inner shape of the transition part 11 is shaped and can be pressed into it is trained.
  • a positioning means 32 is indicated by dashed lines.
  • the feed channels 31, 31 'of the Transitional part two cylindrical openings, the axes of which are parallel or inclined (see Fig. 1 and 4) to each other from the outlet openings 21 of the Lead container 2 to the static mixer 4.
  • the area of the transition piece 11 is a third Embodiment shown.
  • the device that is known from US-A 5 413 253 is known, serve to fix a rotationally fixed position two sleeve-shaped positioning means 33, which simultaneously the feed channels 31st form.
  • the positioning means 33 constructed in this way have the advantage that when changing the device 1 from the outlet openings 21 of the Container 2 removes part of the content that may be contaminated becomes.
  • sealing ribs 34 and 35 in front of the mixer 4 prevent the Eject components laterally into the environment.
  • the sealing rib 35, the outer circumference of the transition piece 3 is arranged together with an annular groove 135 into which the sealing rib 35 is snapped, one Anchoring in the transition part 11.
  • FIG. 6 shows an example in which, in contrast to that of FIG. 5, the Transition part 11 by means of a union nut 5 on the container 2 is attachable.
  • the transition piece 3 does not have to be rotatable.
  • Its outer contour, which must be shaped to fit into the transition part 11, can have a cross section, the outer sides of which are uniform Form polygon. For example, if this polygon is a hexagon, there are six discrete rotary positions, in which the transition piece 3 in the Transitional part 11 is insertable. So that a good seal against the outside is present, the transition piece 3 can also be glued into the transition part 11, welded in or otherwise inseparably connected to it (by Shrink or press fit). With such an unsolvable Fixation is also prevented that the transition piece 3 from the Transition part 11 can fall out. Between transition piece 3 and Transition part 11 can at the high pressures that occur in the mixer can occur (up to 20 bar), no product can escape laterally. The fixation The transition piece 3 also has the advantage that the transition piece 3 When replacing a used mixer, do not put it on a cartridge remains, so the new mixer can be used on the used one without any problems Cartridge can be inserted.
  • FIG. 7 shows a transition part 11 of a device according to the invention a cartridge 2 with "central metering": the feed channels - and the same applies to the outlet openings of the cartridge 2 - are by a centrally arranged cylindrical opening 31a and one to it concentrically arranged, annular gap-shaped opening 31b is formed.
  • This structure is made up of a bundle of four parallel, parallelepiped-shaped strands formed strands; the Chambers are with openings - the number of which is usually four - with Chambers of adjacent strands connected, being within one strand the chambers are separated from each other by closed walls.
  • a such a mixer structure gives good results over a comparatively short distance Mixed results.
  • the running-in conditions which depend on the rotational position of the Transition piece 3 depend on the mixer structure 4, have none disruptive influence on the mixing quality.
  • the two- or multi-chamber container 2 can also be part of one Dosing device in which the chambers of the container 2 Passage areas for quantities to be dosed and separately supplied are mixing components.
