Abstract

A dispensing apparatus for mixing and dispensing multi-component masses including a multi-component cartridge or syringe having a plurality of chambers, a mixer element having a longitudinal axis and a mixer housing placed over the mixer element. The outer surface of the mixer element and the inner wall of the mixer housing have a cooperating guide element which only allows a displacement of the mixer housing at the mixer element along the longitudinal axis of the mixer element. The mixer housing is axially displaceably connected to the multi-component cartridge. The mixer housing and the mixer element are displaceable against one another in an axial direction in the closed and dispensing positions. A rotary element, the mixer housing and the multi-component cartridge have a cooperating interaction element in which the rotary element rotates such that an axial relative movement results between the mixer housing and the multi-component cartridge.
