Brush for applying for nail polish

Abstract

The present invention provides a brush for application of nail polish to the fingernails. The brush comprises a distal portion tapered in width and thickness to form a wedge-shaped or pointed tip. This tapered shape allows the use of a relatively thick brush, capable of holding a sufficient amount of nail polish to completely coat a single fingernail, while permitting the coating of a fingernail without getting nail polish in surrounding tissue.

Description

TECHNICAL FIELD OF THE INVENTION [0001] The present invention relates to a brush for applying nail polish to fingernails. (Nail polish is also known as nail varnish or nail enamel.) Nail polishes are typically viscous liquids which harden by solvent evaporation, and are frequently pigmented. [0002] Nail polish applicators known in the art generally consist of a small brush or pad, which is attached to a stem; the stem in turn is usually attached to the cap which serves to seal the opening of the nail polish container. When the container is closed by the cap, the applicator extends into the nail polish in the container. The cap typically serves as a handle for the applicator, and is frequently of a shape facilitating such use. [0003] In applying nail polish to a fingernail, the brush or other type of applicator is dipped into the nail polish container, then withdrawn and applied to the nail so as to coat or paint the nail. It is desirable that the applicator carry a sufficient load o...

Benefits of technology

[0011] It is an objective of the present invention to provide a brush for the application of nail polish which, when dipped into nail polish in a reservoir, will take up a sufficient quantity of nail polish to coat a fingernail in a single application, without requiring further dipping into the nail polish reservoir.

[0012] It is a further objective of the invention to provide a brush for the application of nail polish which facilitates coating the desired nail surface completely without getting polish on the surrounding cuticle or finger surface.

[0015] It is a still further objective of the invention to provide brush for the application of nail polish which is simple and inexpensive to manufacture.

[0016] The present invention provides a brush for the application of nail polish the distal end of which is tapered in two substantially perpendicular directions, with the angle of the two tapers being chosen independently for optimum coating accuracy and conformity to the fingernail shape. The dual-tapered design of the invention allows a substantially fuller brush to be used, to allow fuller loading of the brush with nail polish, without sacrificing accuracy in applying the nail polish to the fingernail.

Problems solved by technology

Nail polish is formulated to dry or set rapidly, and with multiple dip-and-apply operations it is difficult to avoid undesirable ridges or other visible marks caused by premature drying of a first partial application before a second application to complete the coverage can be performed.

Such devices are characterized by manufacturing complexity, and are relatively expensive to fabricate.

They are prone to clogging; and have not met with widespread acceptance.

None of these brushes are completely successful in carrying a sufficient load of nail polish to cover a fingernail in a single dip-and-apply operation while controlling the shape of the applicator at the applicator-fingernail interface so as to facilitate accurate coverage of the fingernail without getting nail polish on surrounding tissue.
