Abstract

A pot (1) for a cosmetic product comprises a body (12) intended to receive a removable cartridge (300) of cosmetic product, and a mechanism for guiding a movement of the removable cartridge (300) relative to the body (12). The mechanism comprises a drive ring (100), a retaining ring (200) of the removable cartridge (300), a kinematic connection between the drive ring (100) and the body (12), with a single degree of freedom of movement, in rotation about the reference axis (O), a kinematic connection between the drive ring (100) and the retaining ring (200) with a single degree of freedom of movement, in translation along the reference axis (O), and a kinematic connection between the retaining ring (200) and the body (12), with a single degree of freedom of movement, of helical movement along the helical trajectory.
