In this arrangement, the cartridges 11a, 11b comprise separate cardboard sleeves 22, which are respectively provided with a terminating plate 23 and a plunger element 24. The cardboard sleeves are introduced into the receiving shaft 4, which can be closed by a pressure-resistant cartridge housing 5 enclosing the cardboard sleeves 22 flush with them. Also provided between the static mixer 6 and the cardboard sleeves 22 is a head piece 16, which can be inserted into the receiving shaft 4 and has separate flow channels 28a, 28b which are open towards the cardboard sleeves 22 and merge directly at the inlet into the static mixer 6.
