Abstract
The mixer of the mixer-cartridge assembly comprises a housing, an inlet section having an individual inlet for each outlet of the cartridge and a mixer element group. The mixer inlet section comprising a separating element and the mixer element group are arranged thus, that while sealingly connecting the mixer to the cartridge, the inlets of the mixer remain aligned with the corresponding and matching outlets of the cartridge as well as with the separating element and with the dividing element of the mixer element group for optimizing the mixing of the components. For mixer attachment, the mixer housing comprises bayonet lugs cooperating with bayonet prongs on the cartridge, whereby the housing is rotated while the mixer inlet section, separating element 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.
