  • Patent number: 10264927
    Abstract: The brushhead includes a brushhead base member and at least one outer ring of bristles mounted thereto, the brush base member being non-oscillating. An inner assembly is adapted to capture a solid, semi-solid, gel or the like non-Newtonian balm element having shear thinning characteristics. In an embodiment, the inner assembly is adapted to receive energy from an oscillating action of the inner assembly produced by a motor in the appliance to which the brushhead is attachable. Oscillation of the inner portion at a selected frequency and amplitude results in the solid, semi-solid, gel or the like balm element changing to a liquid in a shear thinning effect, the liquid being useful for removal of makeup.

  • Patent number: 8726448
    Abstract: Provided is a core/sheath composite filament for toothbrushes which exhibits excellent hardness, durability and feeling of use when used in toothbrushes, is less prone to falling out when tufted into the tufting plate, and makes it possible to improve stain-removal properties. Also provided is a toothbrush using said core/sheath composite filament. A toothbrush is configured using bundles of bristles configured from core/sheath composite filaments that have a quadrangular cross section in the plane perpendicular to the lengthwise direction and comprise a core (2), which is formed from a synthetic resin fiber, and a sheath (3), which integrally covers the core (2) and is formed from an elastomer that is compatible with the synthetic resin constituting the core (2). Tufts configured from a plurality of the core/sheath composite filaments (1) are tufted in the center portion of a tufting plate.

  • Patent number: 8595886
    Abstract: A bristle configuration providing enhanced cleaning of teeth. At least one elongated bristle tuft is formed to at least partially enclose an area, and a complementary-shaped tuft is provided in the at least partially enclosed area. The elongated tuft and the complementary tuft have angled profiles angled to a different degree, and preferably also in a different direction. A series of elongated tufts with angled profiles may be provided to form an overall bristle profile providing enhanced cleaning of teeth. In addition, one or more tufts may be provided along the elongated tufts to form another tuft pattern along the pattern formed by the elongated tufts. In one embodiment, the other tuft pattern presents a contoured bristle profile angled to a different degree from the profile of the elongated tufts along which the other tuft pattern is provided.

  • Patent number: 8578948
    Abstract: A cosmetic brush includes bristles made from shape memory polymer (SMP) filaments or fibers. The shape memory polymer filaments are selected to exhibit a first shape during assembly of the brush, and a second shape after exposure to an external stimulus in the form of heat or other energy. The SMP filaments are initially assembled to the base of the brush. The first shape can be straight to facilitate assembly of the fibers to the base. The second shape, after assembly and after being subjected to the external stimulus, can be any bristle shape suitable for enhancing the function of the brush, e.g., kinked, wavy or coiled. The brush may be comprised solely of SMP filaments, or may be a blend of SMP filaments and any other suitable filament (e.g., nylon, natural plant or animal fibers, etc.).
