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.
A mixer and a multiple reactive component dispensing device assembly, in particular a two-component cartridge, the mixer comprising a mixer housing, a mixer element group, a mixer inlet section having separate inlets for each outlet of the cartridge, the cartridge comprising at least two containers and an outlet area with separate outlets for each container, the mixer and the cartridge being provided with cooperating attaching means, wherein said mixer inlet section of the mixer comprises separating means for maintaining separation of the components beyond the separate inlets, the mixer element group and the inlet section being arranged such, that while sealingly connecting the mixer to the cartridge, the inlets of the mixer inlet section remain aligned with the corresponding and matching outlets of the cartridge and the separating means are --after attaching the mixer --aligned with a first dividing element of the mixer element group.
