  • Patent number: 5727891
    Abstract: The dispenser for lip-salve or similar ointment includes a tube, an elevator axially movable within the tube for expelling the ointment, and a screw rotatable within the cylinder and interacting with the elevator for moving the elevator within the tube. The internal threads on the elevator interact with the external threads on the screw when the screw is rotated. The elevator is generally cup-shaped, and is arranged to prevent relative rotation between the elevator and the tube. A knob is integral with the screw and external of the tube, and a groove in the knob and a collar in the tube permit relative rotation of the knob and screw with the tube but prevents relative axial movement between the tube and the screw. At least one inclined plane is on the bottom of the cup-shaped elevator and interacts with at least one inclined plane on the knob, within the tube, whereby when turning the knob, the inclined planes on the knob forceably push the inclined planes on the elevator axially within the tube.

  • Patent number: 5609430
    Abstract: There is provided a device for dispensing a semi-solid or highly viscous product, such as a cosmetic product or pomade, which tends to vaporize and shrink with the passage of time. The device includes a support member to prevent the product from moving axially, radially or otherwise undesirably within the support member. The inner wall of the support member includes a plurality of radially curved and inwardly extending ribs that support the product therein without fracturing the product when it is inserted into the support member. The ribs support the product to prevent the product from moving axially and orbitally with respect to the support member.

  • Patent number: 5547302
    Abstract: The present invention relates to improved product dispensers for various products, including solids, gels, semi-solids, and other substantially solid products. In a preferred embodiment of the present invention, the dispenser is in the form of an improved twist-up type dispenser with an application/distribution surface in the form of a mesh applicator head for covering the exposed end of a solid stick of product. The dispenser includes a force-limiting mechanism to limit the force exerted by the product on the mesh applicator head during pre-loading to prevent extrusion of the product. The dispenser further includes a force-maintaining mechanism to maintain the surface of the product in continuous intimate contact with the mesh applicator head during the application process. The surface of the product exposed via the apertures is sheared off in conventional fashion, and the mesh provides for a more even distribution of the product than conventional solid stick-type dispensers.

    Abstract: A cosmetic pencil capable of advancing a soft cosmetic mass a short predetermined distance. The pencil has a lower barrel which includes a gripping disk stop. A hollow sheath member is held in the lower barrel and has an outwardly facing cam surface. A holding tube is rotatably inserted into the lower barrel and surrounds the sheath member. The holding tube also has a cam surface, and a spring member and gripping disk surround a push rod which extends into the center portion of the sheath which holds the soft cosmetic mass. Turning the holding tube forces the sheath inwardly, and the gripping disk holds the push rod steady with respect to the lower barrel and, thus, a small amount of cosmetic mass is moved upwardly by the movement of the sheath with respect to the push rod.

  • Patent number: 4969763
    Abstract: A thrust-action mechanical pencil having a lead-forwarding mechanism and an outer sleeve, the lead-forwarding mechanism being inserted from the rear end of the outer sleeve. An elastic member to prevent looseness is inserted between a chuck ring sleeve, and an inner ring provided on the inside of the outer sleeve to prevent forward movement. A tubular retaining sleeve having a full length slit is installed between a mouth piece and a stepped portion of the lead forewarding mechanism. A retaining portion on the forward end of the retaining sleeve is set between the mouth piece and the forward end of the outer sleeve to retain the lead-forwarding mechanism in the pencil.

  • Patent number: 4954000
    Abstract: The invention relates to a dispenser of a compact product (3) contained in a cylindrical reservoir (1); the product (3) is ejected via a plunger (4) that is displaceable in translation in the reservoir and is mounted at the end of a threaded rod (5), which cooperates with a nut (9). The rod (5) is driven in rotation incrementally via a pushbutton (8). The support (7) of the mechanism and of the nut (9) is movable with respect to the reservoir (1) by means of a thread. The nut (9) which cooperates with the rod (5) is slit along a diametrical plane, to allow the re-pressing of the rod when the half-nuts are capable of spreading apart. The reservoir includes a frustoconical surface 1c, which assures the pinching of the half-screws when the mechanism is put into place at the base of the full reservoir.

  • Patent number: 4921366
    Abstract: A container for a cosmetic preparation such as mascara, lip gloss, etc., including a tubular inner plastic container and an outer metal shell which substantially encloses, and is substantially immovably fixed to, the inner container. The metal shell can serve to inhibit escape of vapor from the cosmetic solvent through the container wall. For improved integrity of the container, the inner surface of the metal shell can be formed with a set of circumferentially spaced, axially extending ribs which bite into the plastic of the inner container, when the container is assembled by pushing the shell onto the inner container, to form grooves in which the ribs engage tightly. An aperture can be formed in the outer shell for displaying to the user the color of the contained cosmetic preparation.

  • Patent number: 4915528
    Abstract: The present invention relates to a dispenser of the propel/repel type, typically used for solid stick deodorants. The dispenser includes a container, a piston mounted on a threaded rod, and an actuating wheel to rotate the rod and either advance the piston toward a product outlet or retracted it away from the outlet. Filling with molten deodorant material can be effected either through the top (i.e., the product outlet) or the bottom of the dispenser. When top-filling, the container is filled through the product outlet, while the piston is fully retracted. Alternatively, the container can be bottom-filled with a cover over the product outlet simply by advancing the piston slightly toward the product outlet, injecting molten deodorant material through openings in the piston and container, and fully retracting the piston to close the filling openings. Once filled by either technique, the dispenser contents are allowed to cool and solidify.

The interior wall of the cup includes a plurality of spaced axially disposed and radially inwardly projecting ribs of dove-tail cross-section. These ribs bite into the stick and function as dove-tail locks to prevent the outer surface of the stick from moving axially and rotationally with respect to the cup, even if stick shrinkage takes place. A screw type dispenser is also described as typical of the types of dispenser with which the cup may be used.

  • Patent number: 4750882
    Abstract: On the top of a mould above each of several cavities for moulding sticks of lipstick, is disposed a first tubular element of a cup comprising an external device for catch-engagement with a second tubular element of the cup, which second tubular element is intended to cooperate with the rest of the case, namely a shell with its internal liner and sleeve. The composition of the lipstick is cast through the first tubular element portion to fill the cavity and at least partly fill the internal space of the first tubular element. After solidification, the case is brought above each cavity to mount the second tubular element in the upper portion of the case until the second tubular element is catch-engaged on the first tubular element. The unit thus formed is extracted from the mould by upward translation and the lipstick thus cast is retracted into its case.
