<p>The device has a component (10) with an axis (X) and a slit (51) extending partially perpendicular to the axis. Another component (20) rotates with respect to the component (10) around the axis and has a pin engaged in the slit. The pin has a rounded or beveled free end, and edges of the slit have notches. An applicator is detachably fixed on the component (10) and includes a stem and an application unit. The slit and the pin are configured such that a displacement of the pin in the slit during the relative rotation of the components causes a relative axial displacement of the components.</p> |
