  • Patent number: 8777506
    Abstract: A liquid applicator includes a liquid pressing mechanism (liquid pressing means) for pressurizing an application liquid inside a main body so as to supply application liquid to an applying member by the pressing of the liquid pressing mechanism. The applying member is made of an elastic material and is formed with a communication path of a passage hole for communication between the inside and outside of main body, and an applying portion of the applying member is formed projected further forward from an ejection opening of communication path. The liquid applicator that can simply apply an application liquid, even it is high in viscosity, over a wide area.

  • Patent number: 8206051
    Abstract: A cosmetic-containing applicator. The applicator is mounted, at its tip end, with an applicator body in which a flange-shaped engagement part is formed at an outer periphery at a rear end of a fiber bundle, comprising an accommodating part accommodating liquid cosmetics, a tip casing mounted on a tip end side of the accommodating part and formed with an insertion hole in which the applicator body (30) is mountable, a guiding part for guiding the cosmetics from the accommodating part to the applicator body, and a reduced-diameter part formed as an inwardly facing flange and reducing in diameter between the insertion hole and the guiding part. The reduced-diameter part is divided into claw-shaped holding pieces by slits, and its smallest-diameter part has a diameter smaller than an outer diameter of the engagement part.
