  • Patent number: 10674807
    Abstract: A cosmetic brush is provided that is capable of enhancing an ability to retain a liquid cosmetic material and making fine adjustment to the eyelashes easier. The cosmetic brush comprises a core wire part and a bristle group radially attached to the core wire part around an axis of the core wire part continuously in a helical state in an axial direction of the core wire part. The bristle group has bristles each constituted by integrating a basic fiber made up of a plurality of bundled constituent fibers and a wound fiber helically wound around an outer circumferential surface of the basic fiber.

  • Publication number: 20190159576
    Abstract: Provided is a cosmetic brush having bristles that easily go between thin eyelashes and easily catch eyelashes when rolling up, and a manufacturing method of the same. A cosmetic brush includes an applying portion formed into a substantially columnar shape as a whole in which bristles are spread radially from a core wire portion evenly in a circumferential direction of the core wire portion and continued in a helicoidal fashion in an axial direction of the core wire portion, and tip ends of the bristles are uniformly bent at substantially the same angle forward or rearward in the axial direction of the core wire portion, and tapered toward tip ends.

  • Patent number: 9414663
    Abstract: Provided is a tool for applying cosmetics for mascara and eyebrow cosmetics which allows applying a liquid cosmetic in an appropriate amount to eyelashes or eyebrows, and with which a previously unexperienced feeling of use can be obtained. In an application tool (1) for which a plurality of bristles (30) are fixed in a double-folded manner to the inside of a long groove (12), which is formed at a partial side surface of a brush portion (10) formed at a leading end side of a brush shaft (6), comb teeth (26) are integrally formed at a predetermined pitch in a brush portion axial direction on an exposed surface (21) of the fastener (20). As a result of forming the comb teeth (26) in a space that is wide between two lines of bristle groups (30a, 30b), the liquid pool space is narrowed accordingly, so that excessive pooling of a liquid cosmetic (2) in the brush portion (10) can be prevented.

  • Patent number: 9259074
    Abstract: A cosmetic application tool is provided which includes an applying portion attached and integrated with a leading end portion of a brush shaft. The applying portion includes a flat, plate-shaped portion surrounded by a hollow, skirt-shaped portion at its distal end. When the brush shaft is drawn out of a cosmetic container, the skirt-shaped hollow portion of the applying portion is flattened by a wiper provided in a surrounding manner within the cosmetic container, so that some of the liquid cosmetic that has been pooled in the skirt-shaped hollow portion is pushed out over the flat plate-shaped portion while some is retained in the skirt-shaped hollow portion of the applying portion.
