  • Patent number: 5490529
    Abstract: In a mascara brush, with a plurality of bristles fixed in place between two twisted wire segments and extending to all sides away from these twisted wire segments, the wire segments being surrounded by a plastic coating, it is provided, for the purpose of achieving increased liquid absorbing capacity, that the plastic coating consists of a fluid absorbent, in particular open-cell, foamed material.It may further be provided that the foamed coating is roughened or fringed to such an extent that the bristles are formed by this roughening or fringing.

  • Patent number: 5363529
    Abstract: A dental brush comprises two intertwisted wire sections between which fibers for cleaning the teeth and tooth gaps are arrested by the twisting. To achieve an increased retaining force acting on the fibers, it is provided in such a dental brush that at least one of the wire sections has a fin extending in the longitudinal direction.

  • Patent number: 5355547
    Abstract: A dental cleaning brush, in particular an interdental brush, comprising a plurality of fiber portions retained between two twisted wire sections and extending away from the latter, has at least a certain part of the fiber portions formed such that they extend approximately in the longitudinal direction of the wire sections or the brush core, respectively, in order that painful galvanic effects during the use be avoided.

  • Patent number: 5313684
    Abstract: In a holding device comprising a handle and a holding section for exchangeably arresting a dental cleaning brush with a wire stem, the holding section having a bore extending about perpendicularly to the longitudinal axis of the holder and approximately corresponding to the diameter of the wire stem of the brush and into which the stem of the brush can be inserted, a longitudinally displaceable locking member being provided to arrest the stem safeguarded against rotation by a longitudinal slot after its being bent by 90.degree.

  • Patent number: 5161554
    Abstract: In a brush, in particular a mascara brush, in which a plurality of bristles is secured between twisted segments of wire and extends on all sides from these twisted wire segments, it is provided for attaining a uniform distribution of tips while avoiding capillary effects at the bristles, that the bristles (4) are embodied as segments of fibers of round cross section, the diameter (D1 or D2) of which is alternatingly larger and smaller, viewed longitudinally.

  • Patent number: 5160057
    Abstract: Reducing wear and achieving an even more exact position, in particular with containers (1) of soft plastics, is achieved in a container (1) for cosmetics comprising at least one stop shoulder (8) and a return stop (10) for fixing a screw closure cap (14) in a defined end position. The extent (E) of the angle at circumference of the return stop (10) in relation to the position of the start of the thread and the thread pitch and the position of the stop shoulder at the container shoulder (3) are chosen in such a way that in the course of closing, the catch projection on the screw closure cap (14) contacts the top of the return stop (10) and from there arrives in the stop position in the course of essentially downward movement.

  • Patent number: 5141347
    Abstract: The invention relates to a reservoir for cosmetics, in particular a mascara unit, comprising a main body of a comparatively soft plastic material, with a threaded neck, on which a screw cap can be screwed, with at least one stop shoulder and at least one return stop in the form of a locking arrangement being provided at the foot of the threaded neck at the shoulder of the reservoir to achieve a defined end position of the screw cap. In order to overcome the wear problems with such soft plastic material which are encountered by known devices, it is provided that an attachment of a comparatively hard material is arranged on the reservoir at the foot of the threaded neck, on which attachment the stop shoulder and the return stop are formed.

  • Patent number: 5133590
    Abstract: The invention relates to a mascara brush with bristles bound by twisting in a twin-layer wire core, the bristles consisting of multiple fibres bound by means of a binding agent which can be dissolved out.Furthermore, the invention relates to a method of manufacture of a mascara brush, the bound multiple layer bristles being bound by twisting into the wire core and subsequently, as a result of the dissolving out of the binding agent with a solvent, being split apart into the individual fibres.

  • Patent number: 5040914
    Abstract: In a device to apply cosmetic materials such as powders, pastes or similar substances by means of an applicator which is held against the surface of the cosmetic material in a storage chamber by spring pressure, it is envisioned that, in order to ensure a reliable and induced transfer of the cosmetic material to the applicator when the two housing parts are pulled apart, the pencil-like device be simple in construction, that the applicator (8) for the cosmetic material (19) be rotatably mounted within the respective housing part (1), and that, under the force of the spring (16) when the two housing parts (1 and/or 2) are separated, the rotatably mounted applicator (8) is revolved relative to the fixed storage chamber (18), while maintaining the surface contact between the applicator (8) and the cosmetic material (19) in the storage chamber (18).

  • Patent number: 4982838
    Abstract: A disposable mascara tester for the hygienic testing of cosmetic materials includes a stem, an applicator attached to the stem, a stripper on the stem, and a plastic covering disposed about the stem, the stripper and the applicator. The plastic covering is sealed to thereby define a sealed capsule in which the stem, the stripper and the applicator are encapsulated. The applicator is operable to effect application of a sample of cosmetic material within the sealed capsule upon unsealing of the plastic covering.

  • Patent number: 4961665
    Abstract: A mascara applicator comprises a mascara brush and a mascara container having an opening for insertion of the mascara brush into the container. The brush comprises a cap with an elongate fixing element to which the bristles of the mascara brush are secured, with the bristles extending in a helical configuration along the elongate fixing element. The bristles define first and second different brush diameters, with the large diameter defined by the bristles being larger than the diameter of the opening in the mascara container. The small diameter defined by the bristles is smaller than or at most equal to the diameter of the opening in the mascara container. The tips of the bristles define, along the length of the fixing element, first and second helically extending lines which are displaced at 180.degree. relative to each other.

  • Patent number: 4927283
    Abstract: An applicator device for the application of a liquid or pasty material includes a handle and an applicator detachably mounted on the handle, the applicator having a sealed chamber containing the liquid or pasty material. A manually operated release on the handle is operable to break the seal of the sealed chamber and to provide for release and application of such material from the applicator onto a desired site.
