  • Patent number: 7429140
    Abstract: A case assembly, rotating or non-rotating, containing a cosmetic product such as lipstick, and a closure cap associated with that case by way of complementary attachment and release mechanisms, wherein the rotating case as well as the attachment and release mechanisms for the cap are completely integrated into the latter; and the attachment and release mechanisms are constituted by a hollow piston, movable in translation, disposed concentrically in the bore of the cap and capable of sliding therein, the hollow piston itself having a bore in which the case carrying the lipstick is housed and secured at one end by way of a removable attachment mechanism, the piston furthermore having a locking and unlocking mechanism interposed between the piston and the cap and acting in one direction or the other by axial pressure exerted simultaneously on the cap and on the visible surface of a base of the integrated case, which base is in contact with the piston, so as to cause release, with respect to the cap, of the pisto

  • Publication number: 20060285911
    Abstract: A case (2) assembly (1), rotating or non-rotating, containing a cosmetic product such as lipstick, and a closure cap (3) associated with that case (2) by way of complementary attachment and release means, wherein the rotating case (2) as well as the attachment and release means for the cap (3) are completely integrated into the latter; and those means are constituted by a hollow piston (4), movable in translation, disposed concentrically in the bore (3a) of the cap (3) and capable of sliding therein, the hollow piston (4) itself having a bore (4a) in which the case (2) carrying the lipstick is housed and secured at one end by way of removable attachment means (A, A?), the piston (4) furthermore having a locking and unlocking mechanism (5) interposed between said piston (4) and the cap (3) and acting in one direction or the other by axial pressure exerted simultaneously on the cap (3) and on the visible surface (6a) of a base (6) of the integrated case (2), which base (6) is in contact with the piston (4), so

  • Publication number: 20060127159
    Abstract: A rotary case (1) comprises a base (2) mounted mobile in axial rotation relative to a tubular body (3) wherein is mounted mobile a slide (4) designed to receive a product to be protected. The rotary case (1) comprises a ballast (40) capable of substantially increasing its mass.

  • Publication number: 20060099024
    Abstract: A revolving case (1) comprises a base (2) mounted mobile in axial rotation relative to a tubular body (3). A slide (4) for receiving a product to be protected is movably mounted in the base, the base (2) comprises a guide (20) for driving the slide (4) in axial translation when the base (2) is axially rotated relative to the tubular body (3). The axial rotation of the base (2) relative to the tubular body (3) drives the slide (4) simultaneously in rotation and in axial translation relative to said tubular body (3). The height of the slide (4) and the height of the guide (20) are not greater than the external height of the base (2).

  • Patent number: 6513536
    Abstract: A rotary holder, particularly for a cosmetic product, which includes a base, a pivoting body pivotally mounted on the base, a cursor driven in longitudinal translation by rotational movement of the pivoting body, and a closing cap adapted to be affixed to the pivoting body due to complementary fixing mechanisms. The complementary fixing mechanisms facilitate connection between the cap and the pivoting body along a longitudinal axis of the holder, which prevents respective translation between the cap and the pivoting body, and which leaves the cap free to rotate with respect to the pivoting body about the longitudinal axis.

  • Patent number: 6190074
    Abstract: Turning case mechanism particularly for cosmetic products, composed of a pivoting body mounted in rotation on a main piece, formed by a traveler, base and hinge elements connecting the base to the traveler, between a lower articulation point with the base and an upper articulation point with the traveler; said traveler intended to be mobile between an open or upper position and a closed or lower position, characterized in that when the traveler is in the lower position, the hinge elements are arranged at least in part below the horizontal plane that contains the lower articulation point.

  • Patent number: 6109807
    Abstract: Lipstick refills in a plurality of colors are packaged in a cylindrical body (3), which is clear plastic along its upper half. The body defines one or more helical grooves (7) in a lower half which receive tips (6a, 6b) of a sliding unit (4) in which a stick of lipstick is received. A pointed hollow element (12) covers the stick of lipstick during transportation and sale, but is removed for use. The sliding unit defines one or more longitudinal grooves (5a, 5b) which slidingly receive longitudinally extending ribs (2a, 2b) of a base (1) when detents (8a) of the base snap into annular groove (9) of the body. As the body and base are rotated relative to each other, the interaction of the longitudinal ribs (2a, 2b) and the longitudinal groove (5a, 5b) cause the sliding unit to rotate relative to the body and follow along the spiral grooves extending and retracting the stick of lipstick.
