A mixer for a multi-component dispensing cartridge having at least two storage cylinders. The mixer includes an inlet section (4) and a mixer housing (2) having a mixer element group (3). The inlet section includes side by side separate inlets (4A, 4B) that terminate at an end plate (20) and which are adapted to connect with the storage cylinders. The mixer housing includes an internal face (21) that is parallel with the top surface (19) of the end plate to define a merging chamber (23) therebetween. The components flow from the inlets in a direction parallel to the top surface of the end plate forcing them to premix within the merging chamber before reaching the dividing edge (8) of the first mixer element. The merging chamber can also include a separating ridge (17) dividing the inlet openings (20A, 20B) and a U-shaped baffle (16). The a U-shaped baffle has arms that open towards the smaller inlet opening (20B) and a partial blocking means (18) on top of the baffle for forcing the component flowing out the larger inlet opening (20A) to flow toward the smaller inlet opening and into the open arms of the U-shaped baffle before reaching the dividing edge. This mixer ensures an effective merging of the components before reaching the first mixer element so that the number of mixer elements and the required dispensing force can be reduced. Also, the storage cylinders can have a volumetric ratio other than 1:1. |
