(57) The mixer (83) of the mixer-cartridge assembly comprises a housing (84), an inlet
section (85) having an individual inlet (87, 88) for each outlet (33, 34) of the cartridge
(30) and a mixer element group (3). The mixer inlet section comprising separating
means (3S) and the mixer element group (3) are arranged thus, that while sealingly
connecting the mixer to the cartridge, the inlets (87, 88) of the mixer remain aligned
with the corresponding and matching outlets of the cartridge as well as with the separating
means (3S) and with the dividing element (3D) of the mixer element group (3) for optimizing
the mixing of the components. For mixer attachment, the mixer housing comprises bayonet
lugs (89) cooperating with bayonet prongs (15) on the cartridge, whereby the housing
is rotated while the mixer inlet section, separating means and element group do not
rotate in regard to the cartridge outlets, thus avoiding cross-contamination of the
components at the cartridge/mixer interface and assuring continued separation well
into the mixer up to the first dividing element (3D).
