## 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.

## Claims

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 4)
