  • Patent number: 6209548
    Abstract: A method and apparatus for applying nail paint is disclosed. In a preferred embodiment a pen-like applicator is provided that comprises a barrel wherein nail paint is contained and a nib that is configured for applying nail paint to a nail. In a preferred embodiment the nib is chisel shaped to allow a user great control and precision around a nail's cuticle and the ability to efficiently apply nail paint to a nail's remaining surface area. The chisel shaped nib may be modified to various shapes, such as bi-concave, plano-concave, or meniscus shapes. Additionally, a nail paint that may be used within the pen-like applicator is disclosed. Preferably, such nail paint is formed by mixing a pigment slurry or past with a latex to form an aqueous nail paint, rather than a traditional solvent-based nail paint. In a preferred embodiment, the nail paint used has a sufficiently low viscosity level to allow the nail paint to effectively flow through the nib, and the nail paint used is preferably non-toxic.
