The dosing mechanism includes a double distributor for dispensing two products at the same time. It comprises a box (1) enclosing two distinct containers (2,2'), with a double piston (8) extending across the two containers. The double piston includes a central section to which a control mechanism is attached. This control consists of a screw-threaded shaft (7) attached to the top of the container, with a nut (6) which runs on the shaft. This nut is attached to the double piston, so that rotation of the shaft advances the nut and moves the pistons within their respective containers.
