Abstract: A lipstick mechanism including an internal substantially tubular duct that rotates in an external substantially tubular duct, the ducts having longitudinal slots and helical slots that guide in translation studs of a lipstick-holder cup disposed in the internal tubular duct, the internal duct including a substantially cylindrical base with a restriction relief that bears elastically on a substantially cylindrical surface connected to the external duct, such that the surface connected to the external duct is elastically deformable and the restriction relief is formed by a raised area sunk in the surface.

Abstract: This lipstick mechanism comprising an inner tubular sleeve (1), an outer tubular sleeve (3), a stick-holder cup (2) arranged in the inner tubular sleeve (1). The inner sleeve comprises a cylindrical base (12) in the wall (21) in which are formed friction pads designed to be pressed elastically on a cylindrical bearing surface (7) linked to the outer sleeve (3), a thinned wall (23) completely surrounding the periphery of each pad (22).

Abstract: A case for lipstick and similar materials with respectively rotating concentric tubes with axial movement of cup-slider (2) which bears stick (1) of pasty substance, characterized by the fact that it has a device for braking with respect to rotation and compensation for axial play between the tubes consisting of flange (10), added on or not, connected to the base of internal tube (5) and having at least one flexible extension (14) which bears elastically against edge (15) of the base of external tube (7).

Abstract: In a case equipped with a rotary mechanism for substances in stick form, the danger of accidental disengagement of the nipples of the sliding cup from the guide sleeves at the end of travel of the nipples is eliminated by inserting the edges of the walls of the slots of the inner sleeve within channels formed in the nipples.

Abstract: Device comprising a collar (10a) whose annular base, fixed to the inner member (4a), is extended by a plurality of lugs (9a) which are resiliently deformable radially and whose free ends come into frictional contact within a cylindrical bearing solidly attached to the outer member (6a).

Abstract: A single-use article for packaging fusible substances, in particular for sampling purposes, can be formed in one piece and has a tubular stem. One end of the stem terminates in a perforated dome which supports a thin layer of substance to be sampled and carries a removable cover.

Abstract: A safety pouring closure comprises an inner cap and an outer cap assembled together by snap-engagement, each cap having an off-center orifice, the caps being capable of being rotated relatively between an open position in which the orifices are aligned and a closed position in which the orifices are angularly off-set, at least one blocking lug on the cap engaging in a recess in the cap in the closed position, the lug being capable of being disengaged from the recess by elastic deformation of the cap. The invention is applicable to closures for containers containing products dangerous to children.
