  • Patent number: 5984552
    Abstract: "Lock" for this impel/repel lipstick container comprises a downward extension at the lower end of the slot in the inner body. The extension is adapted to receive the pomade cup lug and is partly defined by a margin portion facing in opposition to the direction in which the lug is moved when the cam is turned to raise the cup. When a user attempts to propel the pomade upward by turning the cam relative to the inner body, the cam track merely forces the lug against the margin portion of the extension. To unlock, the salesperson applies a tool upward into the base of the lipstick container to raise the pomade cup so that the lug moves upward out of the extension.

  • Patent number: 5863144
    Abstract: A lipstick container cover has a cup-shaped insert which sealingly telescopes over a sealed base assembly. The cover insert has an inward peripheral rib which makes line sealing contact with the sleeve. A bump formed on the sleeve raises the rib to vent pressure caused either by pushing the cover on the lipstick container or pressure build-up due to vaporizing solvent after the cover is fully installed. Venting the pressure in the container avoids the lifting off of the cover after installation. Otherwise such lifting unseals the container.

  • Patent number: 5599124
    Abstract: A lipstick comprising a cartridge and a base wherein the base is formed with upward latches which snap barb fashion over an annular shoulder in the lower end of the inner of the cartridge. The pomade cup has a downward projection to hold the latches outward. Specifically, the cup has a downward "stovepipe" which, when the cup is retracted, fits inside the latches to prevent them from springing inward on impact and releasing the cartridge.

  • Patent number: 5324125
    Abstract: A cosmetic applier comprises a container assembly including a tubular sleeve, a cup holder reciprocable inside the sleeve and a cam for raising and retracting the cup holder. A pomade cup assembly includes a cup carrying pomade and an inverted cup-shaped transparent shroud about the pomade and connected to the top of the cup, the shroud having a diameter at least as great as the inner diamater of the sleeve. Interfitting fastener parts are on the cup and holder. In the preferred version, the fastener is of the permanently locking type. The selected pomade cup may be snapped into the holder and the holder and cup retracted by turning the cam so that the shroud, engaging the sleeve and spread by it, pops off the cup and is freed for easy disposal.

  • Patent number: 5320116
    Abstract: Compact has an unlatching slide with a button surface and formed with front and rear cam surfaces. The hinged cover is held closed by a detent and the powder tray is held in the base also by detents. Light finger pressure on the unlatching slide button causes the front cam to force up the hinged cover disengaging the cover detent to open the compact, and heavy finger pressure on the unlatching slide forces the powder tray up disengaging the tray detents and liberating the tray from the frame so that it may be replaced.

  • Patent number: 5302042
    Abstract: A screw-type propel/repel lipstick has a stepped profile along one edge of the slot in the sleeve of a lipstick. The stepped edge is on the lower end of the spiral opening in the cam where the opening overlies the slot. Preferably, the cup lug has a point in its cross section pointing down toward the stepped side of the slot. When the pomade starts to backoff, the point of the lug catches on the stepped profile.

  • Patent number: 5172993
    Abstract: A cosmetic container comprising a tubular base having an internally threaded lower section and an internally smooth upper section mates with a tubular rotatable sleeve extending up from the base. A tubular telescoping screw assembly has one part secured to the base and one part secured to a pomade cup keyed for rotation with the sleeve. A downward tab is formed integrally with the sleeve and has an outward nib on its lower end which presses against the smooth inner surface of the upper section of the base. The nib exerts a frictional drag on the rotation of the sleeve with respect to the base to give the operation of the container a silky "feel".

  • Patent number: 5172992
    Abstract: A mascara container is provided with a stirrer comprising an oblong frame having side elements spaced inward from the container wall. The spacing permits working of the fluid adjacent the stirrer blades against the stationary fluid adhering to the wall of the container, such working and related shear makes the fluid less viscous so that it flows downward in the container.

  • Patent number: 4825516
    Abstract: First and second complementary snap-fastener components locally and in-situ molded to the same side of a single flexible porous substrate and at relatively short spacing from each other, such that the substrate can be folded between these complementary components to permit their selective mutual engagement and disengagement. One of these formations is a stud component and the other is a socket component, and the sizing of their engageable formations is such that a predetermined clearance characterizes a loose fit when in mutually engaged relation. The looseness of this fit bears a predetermined relation to the thickness and flexible deformability of another flexible member or tie element which is interposed between the snap-fastener elements to secure a given selected location of snap-fastener retention to the tie element. Several embodiments are described.

  • Patent number: 4750501
    Abstract: An improved cosmetic applicator is described in which an inner tubular member has cam slots to guide lugs on a carrier. The carrier supports a cosmetic substance such as lipstick and is moved between retracted and exposed positions by the action of helical grooves in an outer tubular member. A cam slot in the inner tubular member is provided with elongate resilient and flexible elements located to restrict the passage of the carrier lugs into and out of off-sets that provide axial carrier locking positions. The lugs can be moved past the elements which flex in a manner that retains an even swivel torque. A rib is mounted on the inner tubular member so as to contact the carrier and impart an even drag thereto.
