AI Technical Summary

Benefits of technology

The present invention is about an applicator brush with a triangular-shaped bristle tuft attached to a stem. The bristles are folded and retained within a socket in the stem. The bristles are aligned in quadrilateral rows, which allows for better control and precision when applying material to a surface. The brush is designed to maintain a narrow path and limited flaring, even when under pressure. The technical effect of this design is improved control and efficiency when applying material to a surface.

Problems solved by technology

When these brushes are used to apply nail polish to a fingernail, the end portion of the tuft of bristles has a tendency to flare out over the surface of the fingernail under the pressure of the person using the brush.
Such flaring often causes difficulty in controlling the nail polish application and / or results in an uneven coat of nail polish over the surface of the fingernail.
The pressure-induced flaring shape or pattern of conventional bristle configurations can also cause undesirable spread of polish to the skin adjacent the fingernail.
Conventional brush applicators are also difficult to use in detail work involving very small or relatively inaccessible areas.

Embodiment Construction

[0016]FIG. 1 illustrates a preferred embodiment of a brush construction according to the present invention wherein a brush 10 includes a plastic stem 14 extending from a cap 12 and a tuft of bristles 16 connected to the stem 14 using a staple 18 in a manner described in more detail hereinafter.

[0017]Cosmetic products and other brush-applied products are often sold to consumers within bottles (not shown) which are sealed by a cap 12. The cap 12 may be any type of sealing closure suitable for a bottle. In a preferred embodiment, the cap 12 is substantially cylindrical and has a closed end portion. An internal bore extends from an open end 21 of the cap 12 through a length of the cap 12 to a closed end portion 20. Although a cylindrical cap is preferred, any shaped cap is suitable for the present invention. For example, the cap may be generally rectangular, square, triangular, or any other geometric shape. The cap 12 may also include ergonomic features, such as concave portions dispose...

Abstract

An applicator brush with an elongate stem. A tuft of elongate bristles extend from a bristle end of the stem and at least a portion of the elongate bristles have substantially triangular cross sections.

Description

RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. § 119(e) to U.S. provisional application Ser. No. 60 / 989,570, filed Nov. 21, 2007, and is a continuation-in-part of pending U.S. application Ser. No. 11 / 580,390, filed Oct. 13, 2006, which claims priority under 35 U.S.C. § 119(e) to U.S. provisional application Ser. No. 60 / 726,769, filed Oct. 14, 2005.BACKGROUND OF THE INVENTION[0002]Nail polish and other fluid cosmetic products are often applied using a brush applicator. The brush applicators are generally attached to the cap of a cosmetic-containing bottle. In a typical arrangement, a circular brush stem extends from the inside bottom surface of the top of the bottle cap. A circular tuft of bristles with circular cross sections typically extends from a circular opening in the distal end of the stem. When these brushes are used to apply nail polish to a fingernail, the end portion of the tuft of bristles has a tendency to flare out over the surface of the fi...
