Abstract: A micropump provided with a cylindrical body (1) containing a measuring chamber (10) defined by a piston (2) and communicating firstly with a tank via an inlet orifice (10a) provided with an inlet valve, and secondly with the outside via an outlet orifice (10b) provided with an outlet valve, the micropump being characterized in that the piston (2) is connected to an external reciprocating actuator, and in that at least one of said valves is constituted by a valve member (3, 6, 7) suitable for being driven in translation by friction contact with said piston (2) successively in one direction and then in the other, and whose stroke inside the chamber (10) is shorter than the stroke of said piston.

Abstract: The invention relates to a device for selectively dispensing liquids from a plurality of independent reservoirs (R), each of which is equipped with a drawing-off member (P) provided with a dispensing head (T) suitable for being actuated by being pressed axially, said device being characterized in that it comprises a single push-button (1) whose bottom face (1a) is provided with a series of axial bushes (10) suitable for engaging simultaneously and removably over one or more dispensing heads (T) by means of said push-button (1) being turned and angularly keyed on a central bearing (2) secured to the reservoirs (R).

Abstract: A handle device for manually grasping an airless dispenser of the type including a drawing-off member provided with a dispensing head and fitted to a flexible pouch by means of a cylindrical fitting, wherein, at the top of the fitting, under the head, the fitting is provided with a set of fins whose bottom faces serve to receive and to be pressed by the fingers of the user.
