Abstract
A liquid product dispenser including a container equipped with several independent compartments, each of which is associated with a pump including a body which is blocked, at the bottom, by a suction valve and, at the top, by an applicator and/or an exhaust valve and which contains a piston mechanism cooperating with an elastic return system, characterized in that the pump bodies are solidly attached to one another in the form of a single shrunk-on ring by a linking spacer which also watertightly covers the container compartments.
