DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

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 to FIG. 1 to FIG. 11 of the drawings, an artificial nail tip and curing composition set 100 according to a preferred embodiment is illustrated, wherein the nail tip curing composition set 100 comprises an Extend Gel 10, an edge-off flat brush 20, a nail filing device 30, a plurality of artificial nail tips 40 embodied and named as GEL-X tips, a pH Bonder 50, and a Non-Acidic Gel Primer 60, as shown in FIG. 11. The Extend Gel 10 is used as GEL-X tips adhesive.

As shown in FIG. 1 of the drawings, before using the nail tip curing composition set 100, a fingernail 90 is wiped to be cleaned by a cotton pad 91 soaked with rubbing alcohol, so that the fingernail 90 is cleaned to remove oil and dust thereon.

As shown in FIG. 2 of the drawings, the pH Bonder 50 is applied on the fingernail 90 to form a pH Bonder layer on the surface of the fingernail 90. When the pH Bonder layer applied on the fingernail 90 is aired rapidly, the Non-Acidic Gel Primer 60 is applied on the fingernail 90. Specifically, as shown in FIG. 3 of the drawings, the Non-Acidic Gel Primer 60 is applied on the fingernail 90 to form a Non-Acidic Gel Prime layer on the surface of the fingernail 90, which is overlapped on the pH Bonder layer. When the Non-Acidic Gel Prime layer applied on the fingernail 90 is aired rapidly, the edge-off flat brush 20 is used to apply a thin layer of the Extend Gel 10 to the fingernail 90. Specifically, as shown in FIG. 4 of the drawings, the thin layer of the Extend Gel 10 is applied on the fingernail 90 to form an Extend Gel layer overlapped on the Non-Acidic Gel Prime layer.

As shown in FIG. 5 of the drawings, according to the preferred embodiment of the present invention, the Extend Gel layer formed by the Extend Gel 10 and overlapped on the Non-Acidic Gel Prime layer on the fingernail 90 is cured with a LED lamp 92 for a period of time, such as about 30 seconds. Alternatively, the Extend Gel layer formed by the Extend Gel 10 and overlapped on the Non-Acidic Gel Prime layer on the fingernail 90 can 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 40, 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 tips 40 on the fingernails, a rough affixing surface 411 is provided on an underside contact surface 41 of 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 surface 411 can 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 411, multiple indented grooves 412 are formed.

According to the preferred embodiment, the rough affixing surface 411 is provided by means of the nail filing device 30. The underside contact surface 41 is filed by the nail filing device 30 to form the rough affixing surface 411 having multiple small indented grooves 412 thereon, as shown in FIG. 6. 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 surface 411 on the underside contact surface 41 of the Gel-X tip 40 is essential for affixing the Gel-X tips 40 to the fingernails according to the preferred embodiment of the present invention.

In other words, starting from a base portion of the underside contact surface 41 of the Gel-X tip, generally half of the underside contact surface 41 is filed to form the rough affixing surface 411. The rough affixing surface 411, especially the presence of the multiple indented grooves 412 formed thereon making the surface 411 a coarse surface, greatly increases the contacting surface area of the rough affixing surface 411 to pick up the Extend Gel 10. Therefore, when the Gel-X tip adhesive, i.e. the Extend Gel 10, can be retained to the rough affixing surface 411 of each of the Gel-X tips 40 than a smooth surface having the same size.

As shown in FIG. 7 of the drawings, a small drop of the Extend Gel 10, which is enough to cover the natural fingernail, is applied to a base portion of the rough affixing surface 411 of the underside contact surface 41 of Gel-X nail tip 40 by the edge-off flat brush 20, generally about ⅓ of the surface area of the natural fingernail, to form an Extend Gel tip layer on the rough affixing surface 411 of the Gel-X tip 40. The Extend Gel 10 will flow into the multiple indented grooves 412 and be retained therein. In other words, the multiple indented grooves 412 of the rough affixing surface 411 can retain more Extend Gel 10. Therefore, when the rough affixing surface 411 is in contact with the fingernail surface, the Extend Gel layer will attach and affix the Gel-X tip 40 onto the fingernail 90, wherein the retaining of the Extend Gel 10 in the multiple indented grooves 412 substantially increases the thickness of the Extend Gel 10 between the Gel-X tip 40 and the fingernail 90 that effectively increases the adhering bonding of the Gel-X tip 40 and the fingernail 90 so as to more firmly affix the Gel-X top 40 with the fingernail 90 with less curing and hardening time.

Referring to in FIG. 8 of the drawings, after the Extend Gel 10 is applied on the rough affixing surface 411 of the underside contact surface 41 of the Gel-X tip 40, the Gel-X nail tip 40 is pressed onto the fingernail 90 gradually from base to tip of the Gel-X nail tip 40 to prevent air bubbles or lifting and to ensure a tight seal.

As shown in FIG. 9 of the drawings, an external force is pressed down the Gel-X tip 40 and the fingernail 90, and then the fingernail 90 with the Gel-X tip 40 are cured with the LED lighting 93 of the LED lamp 92 for seconds such as about 10 seconds. The LED lamp 93, which can be a LED flashlight as shown in FIG. 9 or 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 fingernail 90 with the Gel-X tip 40 pressing down thereon can be placed within the receiving cavity and treated under the LED lighting 93. Eventually, the external force pressing down the Gel-X tip 40 and the fingernail 90 is removed and the LED lighting 93 from the LED lamp 92 is applied around the Gel-X tip 40 to ensure all sides of the Gel-X tip 40 being cured and hardened.

Then, as shown in FIG. 10 of the drawings, the entire fingernail 90 with the Gel-X tip 40 affixed thereon can be cured under the LED lamp 92 for a few seconds such as 30 seconds, until the Extend Gel tip layer on the rough affixing surface 411 of the underside contact surface 41 of the Gel-X tip 40 and the Extend Gel layer on the fingernail 90 are cured and hardened integrally to form a bonding Extend Gel layer between the Gel-X tip 40 and the fingernail 90. In maximum, application of about 2 minutes of LED lighting to affix the Gel-X tip 40 on the fingernail 90 could be more than enough. Alternatively, the entire fingernail 90 is cured by the UV lamp for a few minutes such as about 2 minutes.

It is worth mentioning that since the Extend Gel 10 of the Extend Gel tip layer is retained in the indented grooves 412 of the rough affixing surface 411 of the underside contact surface 41 of the Gel-X tip 40, the Extend Gel 10 retained in the indented grooves 412 can act like roots to hold the Gel-X tip 40 to the fingernail 90 that greatly enhances the bonding and adhering ability of the cured and hardened bonding Extend Gel layer between Gel-X tip 40 and the fingernail 90 while a relatively thin bonding Extend Gel layer is enough to affix the Gel-X tip 40 on the fingernail 90 firmly 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 tips 40 from the fingernails 90, the user may simply soaking the fingernail 90 with the Gel-X tip 40 thereon into an acetone for a period of time and the Gel-X tip 40 will separate from the fingernail 90.
