## Background
This application is a continuation application of U.S. patent application Ser. No. 12/618,252, filed on Nov. 13, 2009, which claims the benefit of U.S. Provisional Application 61/114,278, filed on Nov. 13, 2008, each of which are herein incorporated by reference.


FIELD OF THE INVENTION
This invention relates in general to nail manicure methods, and more particularly to generating designs on the surface of the nail.
BACKGROUND OF THE INVENTION
When receiving a manicure, nail polish is usually applied to the surface of the nail. Various compositions of nail polish have been disclosed in the prior art, each with various desirable features such as quick drying, ease of application or removal, or durability, resistance to breaking or chipping. U.S. Pat. Nos. 2,764,168, 3,982,113, and 4,126,144 disclose nail polish compositions that are easy to remove. Other compositions and devices have been developed to assist in better application of nail polish for a better overall manicure, such as the use of a top coat, base coat, or protective coatings to prevent nail polish from reaching the cuticle area and skin areas proximate to the nail. U.S. Pat. Nos. 4,960,587 and 5,150,726 disclose an adhesive mask for covering the cuticle to prevent nail polish from being accidentally applied to the cuticle. U.S. Pat. No. 2,339,070 and U.S. Patent Application Publication 2007/0277331 discloses coating compositions for protecting the cuticle from unwanted nail polish. Often, it is desirable to use one or more colors to generate a design on the surface of the nail. U.S. Pat. Nos. 3,598,685, 3,885,578, 5,133,369 disclose methods and apparatus for generating designs on the surface of the nail.
Application of nail coating is normally accomplished with a brush or similar application. Application of nail designs is also frequently accomplished through the use of brushes with various sizes to achieved desired design effects, through the use of design stencils or adhesive ornamentation, or through the use of pen-tipped devices that dispense nail color. It is desirable in many circumstances to have designs with precise, well defined edges, however, precise, well defined edges are often difficult to generate when applying nail polish, even with a stencil, as often the removal of the stencil prior to complete drying of the nail polish can leave ill defined edges. In addition to the difficulties of painting a precise design on the surface of a fingernail, generating a freehand design has its limitations because errors are difficult to correct. Removing nail polish and reapplying nail polish can be tedious and time consuming.
It is often difficult to perform a manicure on oneself, and even more challenging to apply designs to the surface of a nail by oneself. Frequent visits to a manicurist can become costly, and services obtained may not always be satisfactory, as the quality of the manicure and/or designs on the nail are subject to the experience and artistic capabilities of the manicurist.
The present inventor has recognized that known prior art methods described, and others, for applying designs to the nail surface have been disadvantageous for various reasons. The present inventor has recognized the need for a method of applying designs to the surface of the nail that is easy to perform on oneself, and minimizes the time consuming errors of correcting misshapen figures on the surface of the nail. The present inventor has recognized the need for a method of applying designs to the surface of the nail which allows the user to adjust the design until the correct configuration has been obtained. The present inventor has recognized the need for a method of applying precise designs to the surface of the nail which are not limited by the design templates of available stencils, or limited to designs available on artificial nails, or to artificial nails for a “French manicure”—manicures designed to resemble a natural nail, and are characterized by natural pink base nails with white tips—comprising French tips that are often unnatural looking and do not conform to the users natural nail tips.
SUMMARY OF THE INVENTION
A method of creating designs on the surface of a finger nail or toenail is disclosed. A first amount of a flowable protective coating is applied over at least a first portion of a surface of a cuticle adjacent the nail, where the protective coating comprises rubber. The first amount of a flowable protective coating is allowed to at least partially dry. A first nail polish is applied to the surface of the nail. An additional amount of the flowable protective coating is applied over one or more portions of the surface of the nail coated with the first nail polish. The additional amount of the flowable protective coating is allowed to at least partially dry. A second nail polish is applied over exposed portions of the nail not covered by the additional amount of the flowable protective coating. The first amount of flowable protective coating and the additional amount of the flowable protective coating are removed by peeling the first amount of flowable protective coating and the additional amount of the flowable protective coating from the cuticle and the nail, respectively, before the second nail polish is completely dry to reveal one or more portions of the nail not covered by the second nail polish and to reveal at least the first portion of the surface of the cuticle adjacent the nail not covered by the first or second nail polish.
The protective coating is fast drying, easily removable, and easily manipulated into desired shapes. The protective coating is quick drying, pliable, easily manipulated, and easily removable to prevent the application of nail polish to the surface of a nail or cuticle.
Numerous other advantages and features of the present invention will be become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims and from the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.
In one embodiment, which can be used to create a French manicure effect, the protective coating 10 is applied to the surface of a fingernail 2 using a brush 20, as illustrated in FIG. 1. The protective coating is applied to portions of the fingernail where one does not desire the application of nail polish. In the case of a French manicure, the area of the nail from the cuticle 3 up to the region where the nail grows out from the nail bed (not shown), or beyond, can be covered with the protective coating 10. The tip 40 of the fingernail where the nail polish for the French manicure tip is to be applied is left uncovered by the protective coating 10. Once the protective coating has at least partially dried so that it is capable of being manipulated or shaped, the user can use a shaping object, such as their fingernails, a cuticle stick 30, or any object that can be used to shape the protective coating, to generate the desired shape of the curved edge for applying the tip color of the nail in a French manicure. FIG. 2 illustrates the shaping of the protective coating to generate the curved edge for the lower boundary of the French manicure tip. The edge 50 prior to shaping maybe be uneven, thus the edge can be shaped using a cuticle stick 30 as illustrated to generate a smoothed edge 55. Once the desired curved edge of the lower French tip boundary has been defined, the user can apply nail polish to the tip 40 of the fingernail. Once the nail polish 60 in the tip of the French manicure has at least partially set, the protective coating 10 is removed as illustrated in FIG. 3, to reveal a nail surface with a painted French manicure tip comprising a precise bottom edge 70.
Additional layers of nail polish, a top coat, or other protective layers can be applied to the nail surface with the painted French manicure tip. Given the present disclosure, it is possible to apply a base coat, a priming layer, or other possible first layers as known to one skilled in the art, to the surface of the nail prior to, or after the application and removal of the protective coat. For example, the protective coat can be applied on top of the base coat, or the protective layer can be applied prior to the application of a base coat adjacent to the protective layer. The base coat can also be applied to the nail surface 2 once the protective coating 10 has been removed.
Given the present disclosure, the ability to provide customized French manicure tip shapes provides many advantageous over prior art French manicure kits. The ability to shape the protective coating into a desired shaped allows the user more freedom in designing their French manicure, and does not limit the user to shapes provided by traditional adhesive coatings, or other pre-set templates such as artificial French manicure nails comprising French tips that are often unnatural looking and do not conform to the users natural nail tips. In one embodiment, the user is able to manipulate the coating to provide a French manicure tip in alignment with their actual nail if desired. The user is also granted more freedom to design their French manicure tips into creative variations such as having a waved bottom edge of the French manicure tip (not shown). The pliable nature of the protective coating allows for the user manipulate the coating into the desired shaped first without the associated worries of applying nail polish freehand, as accurate and complete removal of unwanted nail polish is time consuming.
In another embodiment, the protective coating is used to generate designs on the surface of an nail 90 with an existing nail color. As illustrated in FIG. 4, protective coating 100 is applied in an amount and in a general shape corresponding to the shape of the final design. The coating is applied with a brush 20, onto a surface of a nail 90 with an existing coat of color. Once the protective coating 100 has at least partially set, a shaping object, such as a cuticle stick 30, is used to shape the protective coating into a desired shaped by manipulating edges 110, as illustrated in FIG. 5. Once the protective coating is manipulated into the desired shaped, a second nail polish layer 120 is applied to regions of the nail not covered by the protective coating, as illustrated in FIG. 6. Once the second nail polish layer 120 is applied and has at least partially set, the protective coating 100 is removed to reveal a design pattern of the existing nail color 90. Such treatment of the nails results in neat and attractive colored regions on the nails with shapes of sharply defined edges to meet the desires of the user. In other embodiments, nail polish layer 120 can be applied within an area defined by the protective coating, rather than to an area surrounding the protective coating as illustrated in FIG. 6.
In another embodiment, the protective coating can be used in conjunction with templates, such as a stencil, for users who prefer not to apply the protective coating onto the nail surface without a guiding mechanism. In this embodiment, the stencil is overlaid onto the surface of a nail which may or may not have a pre-existing nail color. A desired stencil shape is chosen, and overlaid onto the surface of the nail. A layer of protective coating is applied to region defined by the stencil. Once the shape of the protective coating has been generated, the user may proceed as illustrated in FIG. 6 and FIG. 7.
In another embodiment, in an effort to attain a precise application of nail polish, the user will apply the protective coating, which is a liquid flowable and fast drying composition, directly to the cuticle 3 or the nail 2 before applying nail polish to the fingernail or toenail. The protective coating 4 may be applied with a tube applicator 5, as shown in FIG. 8. The protective coating is applied as a liquid which upon drying provides an easily removable barrier cover that prevents the nail polish from contacting areas of the nail 2 or areas of the cuticle 3. Once the protective coating has dried sufficiently to provide a barrier, the user would then apply the nail polish. After the application of nail polish to desired areas, the protective coating is easily removed by peeling it from the cuticle 3 or the nail 2. The protective coating can be applied anywhere on or around nail 2 or cuticle 3 in an effort to provide a barrier cover from the application of nail polish to areas where the nail polish is not wanted.
The protective coating can be provided as part of a kit for performing manicures, wherein the kit can contain the protective coating along with other items such as a shaping object, nail polish, and stencils.
The shaping or manipulation of the protective coating can be accomplished by pushing in portions of the protective coating to generate the desired edges of the shape, or by removing uneven edges, for example, by peeling off or causing to peel off, the portions that create the uneven edges, using shaping objects. Removal of uneven edges can also be accomplished by pushing the non-desirable edge portions of the protective coating away from the rest of the protective coating, thus separating it from the protective coating. It is sometimes preferable to pre-define, or outline the area desired to be removed from the protective coating by pressing down on the protective coating, while tracing out the desired area to be removed using the tip of a shaping object, such that the actual removal of the protective coating layer is facilitated.
Objects than can be used to shape or manipulate the protective coating include cuticle sticks, including rubber tipped cuticle sticks, tweezers, metal spatulas, fingernails, tip of a nail file, or any other object capable of manipulating the protective coating into a desired shape. The shaping object is preferably one that will not scratch the surface of the layer beneath the protective coating.
Protective coating can be applied using various devices, including, but not limited to brushes, dispensers, containers, roll-ons, tubes, tubules, and other devices as disclosed in U.S. Patent Application 2007/0277331.
The protective coating comprises rubber and water. Additives such as pH stabilizers, anti-microbial agents, thickeners, coloring agents, curing agents, and scenting agents are optionally added to the protective coating. The rubber can be natural rubber, synthetic rubber, or a combination thereof. Rubber can be in liquid form, solid, or in a cream like consistency. Rubber is combined in suitable proportions with water, if needed, to generate a product with the desired consistency. Typical formulations include 20% to 40% latex, and 80% to 60% water. The rubber can also be dissolved in volatile solvents to enhance the drying process. Latex, sold in liquid forms such as that sold by Graftobian Make-Up or Yulex® Natural Rubber Emulsions, sold by Yulex Corporation company can be used to formulate a protective coating. PH stabilizers such as ammonium hydroxide, potassium hydroxide, triethanolamine, and others types of stabilizing agents known to those skilled in the art can be added to the latex to preserve the pH of the product within a suitable range for cosmetic applications. Thickeners, such as those made from soy, rice, starch, or a combination thereof, and others, can also be used to achieve the desired consistency of the final product. Curing agents such as tetramethylthiuram disulfide, and others can be used to accelerate the curing time.
The protecting coating is preferably quick to dry and able to provide a smooth application. The protective coating is of a consistency such that the shape of the coating as applied will result in the shape of the coating once it is dried so as to minimize the ability of the protective coating to spread out or run, and to maximize the user's control over the application. The consistency of the protective coating is suitable and commensurate with the type of device used to dispense the protective coating. The protective coating is easily removable, preferably by rubbing or peeling, but other methods of removable can be used.
From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
All references, including publications, patent applications, and patents, cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
