<p>Self-contained manual device for mixing and dispensing two liquids contained in two independent portable receptacles (1, 2) which are juxtaposed, the mixture being produced simultaneously with the dispensing by means of two pumps mounted respectively on the two receptacles, each comprising an actuating rod (5, 5'), the pushing-in of which causes the liquid to be expelled from the receptacle, the said pumps being actuable together by a single push-button (3) which can simultaneously be fitted on the two rods for actuating the said pumps in order to press down on the ends of the said rods so as to cause the simultaneous expulsion of two metered amounts of liquid, each one from one receptacle, characterised in that the push-button is mounted on the rods with an axial clearance which can be adjusted in relation to at least the end of one of the rods (5). A rotatary wedge (11) carries cams (19). By rotating the wedge, a cam is positioned opposite the rod (5) of the pump, which determines a selective pushing-in of the pump, thus the choice of a metered amount to be mixed with the metered amount expelled by the other pump. <IMAGE></p> |
