Abstract: A dispensing appliance for a double cartridge comprises a housing for receiving multiple components and a rotatable portion having a thread, the two parts cooperating in such a manner that by rotating the rotatable portion, a multiple plunger acting upon the pistons in the housing is continuously displaceable relative to the housing in the dispensing direction. To this end, the housing is configured to comprise at least two adjacent storage containers, and the thrust force of the rotatable portion is directly transmitted to a multiple plunger. The rotatable portion may have an internal thread and the double plunger a feed flange with a corresponding external thread, in order to actuate the latter in the axial direction upon rotation of the rotatable portion. This arrangement allows dispensing even highly viscous materials with little manual force under high pressure in a precisely metered manner.
