Abstract:
1. 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 , 20 a ) 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 ).
