United States Patent 3,425,426 NAIL PATCH AND METHOD OF APPLICATION Frederic P. Welanetz, 13055 Moorpark St., Apt. 4, North Hollywood, Calif. 91604 No Drawing. Filed Sept. 16, 1965, Ser. No. 487,893 U.S. Cl. 132-73 12 Claims Int. Cl. A45d 29/00 ABSTRACT OF THE DISCLOSURE Nail repair is provided for by a patch material of very shear thickness fabric impregnated with a binding solution i.e. cellulose nitrate which is solvent activatable to adhere the nail patch material to the nail.

This invention relates to improvements in human nail coverings and to methods for their application to a nail surface for any desired purpose, although especially as patches on split or broken nails.

Heretofore, various expedients have been proposed or employed for nail covering or patching, most of which have left much to be desired because of such limitations as undesirable bulk, thickness, lack of strength and conspicuousness of the patch, as well as the necessity for troublesome application of adhesive to secure the patch to the nail. Prior patches also have presented problems in attempting to fully conceal them even beneath polish coatings.

The invention has for its general object to provide for nail covering or patching in a manner permitting use of virtually film thickness of concealable exceptionally strong material fully conformable to the nail, and by simple solvent application to the exposed surface of the material to adhere it to the nail surface.

Generally, the invention contemplates a patch material of a very sheer thickness fabric impregnated with nitrocellulose or cellulose nitrate which preferably is clear so that the material not only is substantially coloress, but also transparent. Thus the combined properties of thinness and transparency afford maximum inconspicuousness to the applied patch as such, and virtually complete concealability beneath colored nail polish or the like.

Of particular importance are the qualities and properties of the fabric employed, that contribute to giving the patch exceptional strength, thinness and transparency. I have used successfully a very sheer woven silk identifiable according to trade nomenclature 2 A Monme woven to have cross threads (warp and woof) respectively at about 200 and 150 threads per inch. This fabric has transparent thinness, exceptional strength and good flexibility, and it is also penetrable for cellulose nitrate impregnation and by solvent for dissolution of the cellulose nitrate.

In preparation, the fabric is uniformly impregnated with a clear (e.g. acetone or other known nitrocellulose solvent) solution of cellulose nitrate, as by passing the fabric over a roll coated with the solution, and allowing the solvent to evaporate, leaving the impregnated fabric dry, clear and transparent. The prepared material may be packaged in any suitable manner, in the form of sheets from which patches may be cut.

For application of the material to a nail surface, it is only necessary to apply a patch size piece of the material to the nail area to be covered, tucking the material under the end of a split or broken nail, and to apply a cellulose nitrate solvent such as acetone or acetone base solvent, or the usual nail cleaner solvent, to the outside of the applied patch, and pressing the latter to the nail. A small amount of the solvent in penetrating the patch fabric, dissolves at least sufficient of the cellulose nitrate to bond the fabric securely and smoothly to the nail surface and edge. Following drying, the patch and nail may be shaped as desired.

The resulting patch, by reason of its transparency, shows the natural nail color and therefore has little visability, and as previously indicated, the patch has complete concealability beneath coatings such as nail polish. The applied patch will continue its adherence to and support of the nail for such period of time as may be required for the nail correction. At any time the patch may be removed by application thereto of acetone or other cellulose nitrate solvent.

I claim:

1. A human nail patch material comprising sheer woven fabric impregnated with cellulose nitrate and being adherable to a nail surface by solvation of said cellulose nitrate by a cellulose nitrate solvent applied to the exposed surface of the material when engaged with the nail.

2. Material according to claim 1, in which said fabric is transparent.

3. Material according to claim 1, in which the impregnated material is transparent.

4. Material according to claim 3, in which the impregnated material is essentially colorless.

5. Material according to claim 1, in which said fabric is silk.

6. Material according to claim 5, in which said fabric is about 2% Monme silk.

7. Material according to claim 1, in which said fabric has cross thread counts respectively in the order of about 200 and per square inch.

8. Material according to claim 7, in which the fabric is silk.

9. The method that includes applying to a human nail surface a sheer woven fabric impregnated with a cellulose nitrate, and applying to the exposed surface of the fabric a cellulose nitrate solvent which penetrates the fabric and causes said cellulose nitrate to bond the fabric to the nail surface.

10. The method that includes applying to a human nail surface a sheer transparent and essentially colorless woven fabric impregnated with cellulose nitrate, and applying to the exposed surface of the fabric a cellulose nitrate solvent which penetrates the fabric and causes cellulose nitrate bondage of the fabric to the nail surface.

11. The method that includes applying to a human nail surface a sheer transparent and essentially colorless woven fabric impregnated with cellulose nitrate, and applying to the exposed surface of the fabric a cellulose nitrate solvent which penetrates the fabric and causes celulose nitrate bondage of the fabric to the nail surface, and applying colored nail polish to the bonded fabric.

12. The method that includes applying to a human nail surface a sheer transparent and essentially colorless woven transparent silk fabric impregnated with cellulose nitrate, and applying to the exposed surface of the fabric cellulose nitrate solvent which penetrates the fabric and causes cellulose nitrate bondage of the fabric to the nail surface, and applying colored nail polish to the bonded fabric.
