Abstract
A cartridge for dispensing a fluid is presented. The cartridge comprises a reservoir chamber for receiving the fluid. The reservoir chamber has a fluid outlet. The cartridge further comprises a controllable dispenser component for dispensing a dispensing volume of the fluid from the reservoir chamber. The dispenser component is connected to the fluid outlet of the reservoir. The cartridge further comprises a single compressible fluid pump with a single elastic pumping element and a conduit extending from the fluid pump towards the fluid outlet. The fluid pump discharges a mixing volume of the fluid from the conduit into the reservoir chamber upon compression of the elastic pumping element. The mixing volume depends on the degree of compression of the elastic pumping element. The fluid pump sucks in the mixing volume from the reservoir into the conduit upon decompression of the elastic pumping element.
