  • Patent number: 6782894
    Abstract: A method of decorating fingernails is disclosed. An applicator having a foam brush on one end and a bristle brush on the other end is obtained. The foam brush has a non-uniform cell structure and the bristle brush is adapted to apply a uniform coating of nail polish. The bristle brush is used to apply a uniform coating of nail polish of one color. Then, the foam brush is partially saturated in nail polish of a color different from the color of the uniform coating. The foam brush is repeatedly pressed against the nail. Due to the non-uniform cell structure of the foam brush, pools of nail polish of different sizes and thicknesses are deposited onto the nail. Some of the pools are thin to allow the color of the uniform coating to be visible therethrough. The uniform coating is left exposed in several locations. Thus, a mottled effect is produced on the fingernail.

  • Publication number: 20030024541
    Abstract: An applicator for decorating finger nails by applying nail polish to the finger nails is described. The applicator consists of an elongated member having a first end and a handle portion. A foam applicator is formed on the first end of the elongated member. The foam applicator is adapted to produce a non-uniform application of nail polish on the finger nails. Perferably, the foam applicator is made from a foam material having a non-uniform density and a non-uniform cell structure. Natural sponge makes an excellent material for constructing foam applicators for the present invention. The applicator may also include a nail polish applicator pad adapted to apply the nail polish in a substantially uniform fashion.
