Mixing system for two-component cartridge

A mixing system for a two-component cartridge having first and second chambers (7, 8) for accommodating plastic materials, said system comprising a neck structure (3, 6) of said two-component cartridge and a mixer (12), the neck structure including an inner neck section (6) and an outer neck section (3), the inner neck section (6) forming an inner essentially cylindrical discharge channel (9) for a first material dispersed in the first chamber (7) and the outer neck section (3) forming between itself and the inner neck section (6) an annular outer discharge channel (10) for a second material component disposed in the second chamber (8), and the mixer (12) having a mixing tube (14) to be mounted onto the neck section structure (3, 6) and including a plurality of mixing elements (16) arranged axially adjacent one another in the mixing tube (14), said neck section structure (3, 6) including means (18) for dividing the material flows of the first material component and of the second material component so as to form a number of annularly alternately arranged axial strands of the first and the second material components, said inner discharge channel (9) including as dividing means (18) at its discharge end star-like arranged pocket-shaped extensions (18) projecting into the annular outer discharge channel (10), and the inner discharge channel (9) including a baffle plate (20, 20a) which, with the mixer (12) installed, is arranged in the area of the discharge opening of the inner discharge channel (9) for directing the first material flow outwardly through the pocket-shaped extensions (18).
