• the invention relates to cases for sticks of pasty material and more particularly the tubes of lipstick.
• a holster for a stick of pasty material generally comprises a base for receiving the stick of pasty material and a cap.
• the holster is adapted to occupy an open position in which a user can deploy the pasty stick and a closed position in which the cap and base are associated so that the holster encloses the stick of pasty material. In this last position, the stick of pasty matter is inaccessible and protected.
• the attraction force exerted between the permanent magnet members is sufficient to maintain the case in the closed position while being sufficiently moderate to allow the user to easily disconnect the base and the cap to pass the case from the closed position to the open position.

• one of the member and the cap carries the member and the other comprises one or more cutouts for housing the member when the case occupies the closed position or forms in non-circular section at the level the junction between the base and the cap.
• the number of cuts therefore determines the number of relative positions that the base and the cap can occupy when the case occupies the closed position.
• permanent magnet members must allow this limited number of relative positions.
• EP-1 095 870 discloses a packaging device for a particularly pasty product which comprises a base and a cap.
• the base has two magnetic means, just like the hood.
• the magnetic means carried by the base and the cap are such that the base and the cap can occupy only a small number of positions when the case is in the closed position.
