A cylinder base part that can rotate on a funnel casing is equipped with a base for its activation, and an internally threaded neck inside of which an externally and internally threaded middle part can be moved telescopically. Inside the middle part, an externally threaded part of a slide part making up the container for the lipstick bar acts telescopically so that rotation of the base part with respect to the funnel casing initially produces an axial and unified movement of the middle part and the slide part, without any rotation of either of these parts. When the middle part reaches its maximum forward position, it moves on to accompany the base part in its rotation movement, continuing the axial movement and in the absence of rotation of the slide part, which allows the container and the lipstick bar, to adopt a geometric configuration.
