  • Patent number: 4022228
    Abstract: A device for removing nail polish and other fingernail coatings comprises a container having an access opening at the top thereof and which contains therein a solvent capable of dissolving the nail polish. A brush having relatively hard, stiff bristles is mounted within the container in such a manner so as to partially surround the access opening. The brush is arranged so that the bristles engage with the fingernail when the finger-tip is inserted through the access opening and the brush functions to scrub and clean the fingernail so as to remove the nail polish therefrom in response to slight movements of the fingertip. The container is composed of opaque plastic material to avoid breakage, minimize weight, and prevent the user from seeing the unsightly nail polish which dissolves in and discolors the solvent.
