ABSTRACT:
A device for the packaging and application of a friable product presented in the form of a lipstick including a tubular element with slide(s), wherein there is slidably mounted a cup intended to receive the lipstick, the cup having at least one stub engaged in a corresponding slide delimited by two longitudinal edges. A cylindrical shell provided with an internal helical groove has the tubular element freely rotatable inside it, with the stubs of the cup engaging in the helical grooves of the shell. Soft friction between the cup and the tubular element is ensured by a tangential elastic deformation of at least one of the longitudinal edges of a slide during the passing of the stub whose width is slightly larger than the width of the slide.
