These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.

The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

Referring totoof the drawings, an artificial nail tip and curing composition setaccording to a preferred embodiment is illustrated, wherein the nail tip curing composition setcomprises an Extend Gel, an edge-off flat brush, a nail filing device, a plurality of artificial nail tipsembodied and named as GEL-X tips, a pH Bonder, and a Non-Acidic Gel Primer, as shown in. The Extend Gelis used as GEL-X tips adhesive.

As shown inof the drawings, before using the nail tip curing composition set, a fingernailis wiped to be cleaned by a cotton padsoaked with rubbing alcohol, so that the fingernailis cleaned to remove oil and dust thereon.

As shown inof the drawings, the pH Bonderis applied on the fingernailto form a pH Bonder layer on the surface of the fingernail. When the pH Bonder layer applied on the fingernailis aired rapidly, the Non-Acidic Gel Primeris applied on the fingernail. Specifically, as shown inof the drawings, the Non-Acidic Gel Primeris applied on the fingernailto form a Non-Acidic Gel Prime layer on the surface of the fingernail, which is overlapped on the pH Bonder layer. When the Non-Acidic Gel Prime layer applied on the fingernailis aired rapidly, the edge-off flat brushis used to apply a thin layer of the Extend Gelto the fingernail. Specifically, as shown inof the drawings, the thin layer of the Extend Gelis applied on the fingernailto form an Extend Gel layer overlapped on the Non-Acidic Gel Prime layer.

As shown inof the drawings, according to the preferred embodiment of the present invention, the Extend Gel layer formed by the Extend Geland overlapped on the Non-Acidic Gel Prime layer on the fingernailis cured with a LED lampfor a period of time, such as about 30 seconds. Alternatively, the Extend Gel layer formed by the Extend Geland overlapped on the Non-Acidic Gel Prime layer on the fingernailcan also be cured with UV lamp for a period of time, such as about 2 minutes.

Regarding to the artificial nail tips, namely Gel-X tips, made of for example acrylic material, are used as the artificial nail tips according to the preferred embodiment of the present invention. Before attaching the Gel-X tipson the fingernails, a rough affixing surfaceis provided on an underside contact surfaceof each Gel-X tip, which is the lower inner portion of the Gel-X tip having a surface area approximately equal to the surface area of the fingernail that the Gel-X tip is going to in contact with and affixing thereon. The rough affixing surfacecan be made when it is manufacturing to provide a coarse surface other than the generally smooth surface required on the underside surface and topside surface of the finger nail. On the rough affixing surface, multiple indented groovesare formed.

According to the preferred embodiment, the rough affixing surfaceis provided by means of the nail filing device. The underside contact surfaceis filed by the nail filing deviceto form the rough affixing surfacehaving multiple small indented groovesthereon, as shown in. It is appreciated that a health fingernail will generally have a smooth surface. In order to enhance the affixing of the artificial nail tip on the fingernail surface, the conventional way to slightly file the fingernail surface and then apply the glue thereon for adhering the artificial nail tip on the fingernail. To prevent causing unnecessary damages to the fingernail, the formation and providing of the rough affixing surfaceon the underside contact surfaceof the Gel-X tipis essential for affixing the Gel-X tipsto the fingernails according to the preferred embodiment of the present invention.

In other words, starting from a base portion of the underside contact surfaceof the Gel-X tip, generally half of the underside contact surfaceis filed to form the rough affixing surface. The rough affixing surface, especially the presence of the multiple indented groovesformed thereon making the surfacea coarse surface, greatly increases the contacting surface area of the rough affixing surfaceto pick up the Extend Gel. Therefore, when the Gel-X tip adhesive, i.e. the Extend Gel, can be retained to the rough affixing surfaceof each of the Gel-X tipsthan a smooth surface having the same size.

As shown inof the drawings, a small drop of the Extend Gel, which is enough to cover the natural fingernail, is applied to a base portion of the rough affixing surfaceof the underside contact surfaceof Gel-X nail tipby the edge-off flat brush, generally about ⅓ of the surface area of the natural fingernail, to form an Extend Gel tip layer on the rough affixing surfaceof the Gel-X tip. The Extend Gelwill flow into the multiple indented groovesand be retained therein. In other words, the multiple indented groovesof the rough affixing surfacecan retain more Extend Gel. Therefore, when the rough affixing surfaceis in contact with the fingernail surface, the Extend Gel layer will attach and affix the Gel-X tiponto the fingernail, wherein the retaining of the Extend Gelin the multiple indented groovessubstantially increases the thickness of the Extend Gelbetween the Gel-X tipand the fingernailthat effectively increases the adhering bonding of the Gel-X tipand the fingernailso as to more firmly affix the Gel-X topwith the fingernailwith less curing and hardening time.

Referring to inof the drawings, after the Extend Gelis applied on the rough affixing surfaceof the underside contact surfaceof the Gel-X tip, the Gel-X nail tipis pressed onto the fingernailgradually from base to tip of the Gel-X nail tipto prevent air bubbles or lifting and to ensure a tight seal.

As shown inof the drawings, an external force is pressed down the Gel-X tipand the fingernail, and then the fingernailwith the Gel-X tipare cured with the LED lightingof the LED lampfor seconds such as about 10 seconds. The LED lamp, which can be a LED flashlight as shown inor a bridge light for sitting on a table surface to define a receiving cavity between the LEDs provided on an underside of the bridge light and the table surface, so that fingernailwith the Gel-X tippressing down thereon can be placed within the receiving cavity and treated under the LED lighting. Eventually, the external force pressing down the Gel-X tipand the fingernailis removed and the LED lightingfrom the LED lampis applied around the Gel-X tipto ensure all sides of the Gel-X tipbeing cured and hardened.

Then, as shown inof the drawings, the entire fingernailwith the Gel-X tipaffixed thereon can be cured under the LED lampfor a few seconds such as 30 seconds, until the Extend Gel tip layer on the rough affixing surfaceof the underside contact surfaceof the Gel-X tipand the Extend Gel layer on the fingernailare cured and hardened integrally to form a bonding Extend Gel layer between the Gel-X tipand the fingernail. In maximum, application of about 2 minutes of LED lighting to affix the Gel-X tipon the fingernailcould be more than enough. Alternatively, the entire fingernailis cured by the UV lamp for a few minutes such as about 2 minutes.

It is worth mentioning that since the Extend Gelof the Extend Gel tip layer is retained in the indented groovesof the rough affixing surfaceof the underside contact surfaceof the Gel-X tip, the Extend Gelretained in the indented groovescan act like roots to hold the Gel-X tipto the fingernailthat greatly enhances the bonding and adhering ability of the cured and hardened bonding Extend Gel layer between Gel-X tipand the fingernailwhile a relatively thin bonding Extend Gel layer is enough to affix the Gel-X tipon the fingernailfirmly for a relatively longer lift span for at least couple weeks. Also, the thinner the bonding Extend Gel layer, the shorter the curing and hardening time by the LED lighting is required that can greatly shorten the total time required for affixing ten nail tips to ten fingernails of the user.

To detach the Gel-X tipsfrom the fingernails, the user may simply soaking the fingernailwith the Gel-X tipthereon into an acetone for a period of time and the Gel-X tipwill separate from the fingernail.

It is worth mentioning that the Extend Gelis used as a GEL-X tip adhesive. The chemical formulation of the Extend Gelis based on acrylate/methacrylate chemistry, and contains monofunctional and multifunctional acrylate/methacrylate monomers/oligomers and photoinitiators. The Extend Gelin the uncured state is a potential sensitizer, a primary eye irritant and a moderate skin irritant.

Specifically, as shown inof the drawings, the chemical composition of the Extend Gelincludes a Polyurethane Acrylate Oligomer, a 2-Hydroxyethyl methacrylate, a 1-Hydroxycyclohexyl phenyl ketoneand a Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide.
