Abstract

System for dispensing a makeup product, having a dispenser (11) that receives at least two cartridges (30), each one having a reservoir containing a base product, the latter leaving the cartridge via an outlet channel (52) of the cartridge, this outlet channel opening out at the outside of the dispenser or near the external surface thereof.

First claim

The invention claimed is:

1. A system for dispensing a makeup product, having
a dispenser having a motorized drive mechanism,
at least two cartridges received in the dispenser, extending along a longitudinal axis X, each cartridge having
a body,
a head,
a reservoir containing a base product,
a piston capable of moving in the body so as to reduce the volume of the reservoir situated under the piston,
a hollow screw on which the piston is screwed, the friction of the piston against the body of the cartridge preventing it from turning when the hollow screw turns, the hollow screw defining a passage via which the product contained in the reservoir can circulate when the piston moves in the direction of a reduction in volume of the reservoir,

a drive piece able for being driven in rotation about the longitudinal axis X of the cartridge by the motorized drive mechanism of the dispenser, the drive piece comprising a dispensing endpiece defining an outlet channel through which the base product leaves the cartridge, this outlet channel opening out at the outside of the dispenser or near the external surface thereof via a dispensing orifice, the drive piece capping and gripping the head of the cartridge,
wherein when the drive piece is driven in rotation about the longitudinal axis X of the cartridge by the motorized drive mechanism of the dispenser, the rotation of the drive piece is transmitted to the head of the cartridge, which can turn relative to the body and drive the hollow screw in order to dispense the base product contained in the cartridge.

2. The system according to claim 1 , the outlet channel of the cartridge opening into a zone in which a mixture of the base products is picked up or close to this zone.

3. The system according to claim 1 , the dispenser being produced with a cup not designed to be removed, into which a mixture of the base products is dispensed, the outlet channel of the cartridge opening out in the bottom of the cup.

4. The system according to claim 1 , the outlet channel of the cartridge opening out in a zone of the dispenser intended for the mounting of a removable outlet interface, which defines a pickup zone.

5. The system according to claim 4 , the outlet interface having a cup.

6. The system according to claim 4 , the outlet interface being designed to be connected to an airbrush stylus.

7. The system according to claim 1 , the dispenser having three cartridges of base products.

8. The system according to claim 1 , the dispenser having seats for receiving the cartridges.

9. The system according to claim 8 , the seats for receiving the cartridges being received removably in the dispenser.

10. The system according to claim 8 , the dispenser having passages for ducts of the cartridges defining the outlet channels.

11. The system according to claim 1 , the dispenser allowing at least two base products to be delivered in variable proportions.

12. The system according to claim 11 , the dispenser allowing at least three base products to be delivered in variable proportions.

13. The system according to claim 1 , the cross section of the outlet channel being between 1 and 3 mm 2 .

14. The system according to claim 1 , the cartridges having ducts engaged in passages of an outlet interface having a cup.

15. The system according to claim 14 , the ducts extending set back from the bottom of the cup.

16. The system according to claim 15 , the ducts extending set back from the bottom of the cup flush with the latter.

17. The system according to claim 1 , the volume of base product initially contained in the cartridge or in each cartridge being between 2 ml and 5 ml.

18. A dispensing system, comprising a dispenser having a housing, and at least one cartridge received in the housing of the dispenser, this cartridge having a body and a piston capable of moving in the body, the housing having a motorized drive mechanism for moving the piston of the cartridge, the or each cartridge having a hollow screw on which the piston is screwed, the piston being able to move axially on the screw as the latter turns, the friction of the piston against the body of the cartridge preventing it from turning when the screw turns, the cartridge having a dispensing endpiece through which the product emerges, this dispensing endpiece being driven in rotation by the drive mechanism for moving the piston, the dispenser having an electronic board for controlling the motorized drive mechanism, this electronic board having the one or more endpieces passing through it.

19. The system according to claim 18 , the housing of the dispenser being of elongate shape along a longitudinal axis, and the dispenser receiving several cartridges arranged in the housing about this axis.

20. The system according to claim 19 , the cartridges being inserted from the rear, and the mixture being delivered from the front.

21. The system according to claim 19 , the cartridges being inserted from the rear, and a mixture of the base products being delivered from the front.

22. The system according to claim 18 having several cartridges, the drive mechanism having a motorization system formed of motors coupled to gearboxes, these motors and gearboxes being of elongate shape parallel to the longitudinal axis of the dispenser, and arranged between the cartridges.

23. The system according to claim 18 , the drive mechanism allowing the base product contained in the or each cartridge to be dispensed at a flow rate of between 10 μl/s and 100 μl/s.

24. The system according to claim 18 , the dispenser allowing at least two base products to be delivered in variable proportions.

25. The system according to claim 18 , the endpiece having at least one anti-rotation relief.

26. The system according to claim 18 , the endpiece bearing a seal.

27. The system according to claim 26 , the seal being an O-ring seal.

28. The system according to claim 18 , the one or more endpieces opening out at one end of the housing.

29. The system according to claim 18 , the board carrying a switch for controlling the operation of the dispenser.

30. A dispensing system, comprising a dispenser having a housing, and at least one cartridge received in the housing of the dispenser, this cartridge having a body and a piston capable of moving in the body, the housing having a motorized drive mechanism for moving the piston of the cartridge, the or each cartridge having a hollow screw on which the piston is screwed, the piston being able to move axially on the screw as the latter turns, the friction of the piston against the body of the cartridge preventing it from turning when the screw turns, the cartridge having a dispensing endpiece through which the product emerges, this dispensing endpiece being driven in rotation by the drive mechanism for moving the piston, the endpiece having two diametrically opposite anti-rotation studs.

31. The system according to claim 30 , the or each cartridge having a hollow screw on which the piston is screwed, the piston being able to move axially on the screw as the latter turns, the friction of the piston against the body of the cartridge preventing it from turning when the screw turns.
