1. Liquid product dispenser comprising a container equipped with several independent compartments, each of which is associated with a pump consisting of a body which is blocked, at the bottom, by a suction valve and, at the top, by an applicator and an exhaust valve and which contains a piston mechanism cooperating with an elastic return system, characterised in that said pump bodies are formed together as a single unitary piece in the form of a single shrunk-on ring including a linking spacer formed integrally between said pump bodies, wherein the single shrunk-on ring also watertightly covers said container compartments; characterised in that said linking spacer has a central sleeve for blocking the elastic return system;characterised in that said applicators have radial shoulders supported by the elastic return system, said radial shoulders supporting a centering finger of the elastic return system, the centering finger extending axially and in a sliding manner in the central sleeve. 2. Dispenser according to claim 1, characterised in that said shrunk-on ring comprises at least one element for watertight connection with the wall of the compartments. 3. Dispenser according to claim 1, characterised in that said applicators are fixed to a cover forming at least one actuator which cooperates with the return system. 4. Dispenser according to claim 1, characterised in that the top side of said applicators comprises a radial groove which opens to the outside via a discharge passage. 5. Dispenser according to claim 3, characterised in that a groove is closed at the top by the bottom side of said cover. 6. Dispenser according to claim 1, characterised in that said shoulders are connected in a central manner forming a single cylinder. 7. Dispenser according to claim 1, characterised in that said compartments are cylindrical and arranged within one another in a nested manner. 8. Dispenser according to claim 1, characterised in that said pump bodies include intake tubes immersed in said container compartments. 9. Dispenser according to claim 1, characterised in that said applicators comprise a lateral skirt slidingly covering the piston, the piston consisting of an inner jacket anchored in the body of the pump and supporting the suction valve. 10. Dispenser according to claim 9, characterised in that said jacket has an axial rod passing through it, the top end of which forms the valve of the exhaust valve. 11. Dispenser according to claim 1, characterised in that said piston consists of a hollow rod covered, at the top, by said applicator and coupled, at its lower part, with an inverted cup. 12. Dispenser according to claim 11, characterised in that said rod is mobile in relation to said cup so as to open the exhaust valve arranged at the bottom end of said rod. 13. Dispenser according to claim 11, characterised in that said pumps are blocked in a watertight manner by bushes inserted in the body around the hollow rods, which are solidly attached to one another by means of a plate. 14. Dispenser according to claim 2, wherein said applicators are fixed to a cover forming at least one actuator which cooperates with the return system. 15. Dispenser according to claim 4, wherein said groove is closed at the top by the bottom side of said cover. 16. Dispenser according to claim 1, wherein said shoulders are connected in a central manner forming a single cylinder. 17. Dispenser according to claim 12, wherein said pumps are blocked in a watertight manner by bushes inserted in the body around the hollow rods, which are solidly attached to one another by means of a plate.
