DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] FIGS. 1 and 2 show artificial nails 10 of the prior art. In each case, the artificial nail 10 includes a one-piece molded body 12 having a distal end 14 and a proximal end 16 opposite the distal end. The proximal end 16 and, more particularly, the bottom surface adjacent the proximal end is sized and shaped to be attachable to the top surface of a natural nail. The distal end 14 may be sized to extend beyond the end of the natural nail when the artificial nail is attached thereto or it may be sized to coincide with the end of the natural nail.

[0026] The nail body 12 can be rounded or it can be straight and it is not limited to any particular dimensions. In other words, the artificial nail 10 can be applied to fingernails and/or toenails and can be made in a variety of sizes and shapes. For instance, the proximal end 16 of the nail body 12 may substantially correspond in size and shape to the full nail bed of a natural fingernail, whereby the artificial nail is termed a full nail cover that is applied over the full nail bed of a natural fingernail. Alternatively, the proximal end 16 may be attachable to only the distal end of a natural fingernail, that is, for example, it may correspond in size and shape to only the distal end of the natural nail bed, whereby the artificial nail is termed a nail tip that is applied to the end of the natural fingernail. Once properly applied, however, it is often difficult to distinguish a tip from a cover.

[0027] FIG. 2 shows an embodiment of an artificial nail disclosed in commonly owned U.S. Pat. No. 6,892,736 to Chang et al. In this embodiment, an application tab 18 extends outwardly from the distal end 14 of the nail body 12, which is adapted to be grasped between the thumb and the forefinger to aid in attachment of the artificial nail 10 to a natural nail. The application tab 18 typically includes a frangible portion 20 adjacent the distal end 14 of the nail body 12 for detaching the application tab from the nail body at a separation line 22.

[0028] As discussed above, it is known in the art to provide indicia 24, indicating the size of the nail 10, on the nail body, as shown in FIG. 1, or on the application tab, as shown in FIG. 2. The indicia 24 is typically molded or etched into the nail body 12 or the application tab 18. However, when molded into the nail body or the application tab, the indicia is often difficult to see in the pre-applied nail. Efforts to improve the visibility only result in the indicia being visible after application of the artificial nail to the natural nail resulting in an undesirable aesthetic appearance. Even when the size indicia is provided on the removable application tab, there still exists the added complexity and expense of a specially designed mold having provisions for forming the indicia into the nail body during the plastic injection molding process.

[0029] Turning now to FIGS. 3 and 4, an artificial nail 50, which solves these problems, is shown. The artificial nail 50 of the present invention is similar in many respects to the artificial nail 10 described in FIGS. 1 and 2. For example, the artificial nail 50 includes a one-piece molded body 52 having a distal end 54 and a proximal end 56 opposite the distal end, wherein the proximal end 56 and, more particularly, the bottom surface 58 adjacent the proximal end is sized and shaped to be attachable to the top surface of a natural nail.

[0030] However, according to the present invention, a pressure sensitive adhesive 60 is applied to the bottom surface 58 and a releasable backing film 62 is applied over the pressure sensitive adhesive to protect the adhesive prior to application of the nail. Indicia 64, indicating the size of the nail 50 is provided on the releasable backing film 62. The indicia 64 is preferably provided on a tab portion 66 of the backing film, as shown in FIG. 3. Alternatively, the indicia 64 can be provided anywhere else on the backing film 62 so as to be visible from the bottom side of the nail.

[0031] In a variant of the present invention, as shown in FIG. 5, the artificial nail can also be provided with features disclosed in commonly owned U.S. Pat. No. 8,528,570 to Chang. Here, a one-touch artificial nail according to the present disclosure generally includes an artificial nail unit 200 having a nail body 210, a double-sided adhesive tape body 110 used for attaching the artificial nail unit 200 to the nail, and a release tape 120. A first cutting line 114 and a second cutting line 124 are respectively formed at the double-sided adhesive tape body 110 and the release tape 120. The first cutting line 114 and the second cutting line 124 are respectively formed through the double-sided adhesive tape body 110 and the release tape 120.

[0032] Therefore, when the double-sided adhesive tape body 110 and the release tape 120 having a planar shape are attached to the nail body 210 having a curved shape, air located between the nail body 210 and the double-sided adhesive tape body 110 is discharged out through the first cutting line 114 and the second cutting line 124. Further, since the first cutting line 114 and the second cutting line 124 are formed with a linear shape, the rigidity of the double-sided adhesive tape may be maintained. In other words, during a process where the release tape 120 is detached from the double-sided adhesive tape body 110, it is possible to prevent the double-sided adhesive tape body 110 from being torn. In addition, since the area of the release tape 120 is greater than the area of the double-sided adhesive tape body 110, it is possible to prevent impurities from being stuck to the double-sided adhesive tape.

[0033] The nail body 210 includes a distal end 211 to be located at a free edge side of the nail, a proximal end 213 to be located at a cuticle side of the nail, lateral sides 215 and an adhesive surface 219 formed at a location facing the nail. The double-sided adhesive tape body 110 includes a plurality of non-connecting portions formed by cutting a plurality of first cutting lines 114, and a connecting portion 112a formed between the first cutting lines 114 so that the plurality of non-connecting portions are not separated from each other.

[0034] The release tape 120 has a greater area than the double-sided adhesive tape body 110 and the double-sided adhesive tape body is attached to the upper portion of the release tape 120 so that the double-sided adhesive tape body 110 is not deviated from the release tape 120. The release tape 120 further preferably includes a grip 122 connecting to and protruding from the outer circumference at one end 211 of the nail body 210.

[0035] The release tape 120 may be made of any one of PE, EVA, PP, POE, and PET, or their copolymers or blends. In addition, the release tape 120 preferably has a tensile strength of 5 kg/cm.sup.2 or above. When the release tape 120 is made of the above materials, the thickness of the release tape 120 is preferably 30 m to 300 m.

[0036] The double-sided adhesive tape body 110 is preferably formed to have a thickness of 150 to 800 m. The peeling strength of the double-sided adhesive tape body 110 is preferably 300 gf/10 mm or above. The double-sided adhesive tape body 110 applied to the one-touch artificial nail according to the present disclosure may be provided in a single layer or a laminate structure where a plurality of layers is laminated.

[0037] As described above, indicia 164, indicating the size of the nail, is provided on the release tape 120. The indicia 164 is preferably provided on the grip 122, but can be applied anywhere else on the release tape 120. The indicia 164 can be formed as cutting lines during the stamping or cutting process to make the release tape. Specifically, the stamping or cutting die used to form the release tape can include raised portions to impress or cut the indicia into the release tape. Alternatively, the indicia 164 can be printed onto the release tape in a subsequent printing process, or can be otherwise applied using any known technique.

[0038] The indicia 64, 164 may indicate the size of the nail body 52, 210 in terms of width, such as by industry recognized sizes ranging from #1 (largest) to #15 (smallest). Alternatively, or preferably in addition to, the indicia 64, 164 may indicate the size of the nail body 52, 210 in terms of lateral and/or longitudinal curvature of the nail. For example, it has been found that because the natural nails vary in both lateral and longitudinal curvature from person to person, it is preferable to provide artificial nails to accommodate these variances. Thus, the nails can be provided with lateral curvatures ranging from extra flat (EF), flat (F), regular (R), high (H) and extra high (EH). Similarly, the nails can be provided with longitudinal curvatures of medium (M) and curved (C). In this manner, a #5 width nail having a flat lateral curvature and a medium longitudinal curvature would include a release tape having indicia reading F-M #5 as similarly shown in FIG. 2.

[0039] FIG. 6 illustrates a typical set 26 of artificial nails 10 formed in accordance with the present invention. The set 26 is preferably fabricated by injection molding as a unitary part including a plurality of spaced differently sized nails 10 connected to a supporting structure 28, such as a central tree. Each of the nails 10 includes a nail body 12, a pressure sensitive adhesive (not shown) applied to an underside of the nail and a release tape 62 covering the pressure sensitive adhesive. In this embodiment, the grip 66 of the release tape 62 for each nail is provided with indicia 64 so that the user can readily see the respective sizes of the nails. As can be seen in FIG. 6, the indicia 64 is different for each nail. Preferably, the nails 10 are arranged on the supporting structure 28 in an aesthetically pleasing, as well as a functional pattern. In particular, the nails 10 are preferably arranged in order of size and are positioned side-by-side along the supporting structure 28. Since all the nails 10 are molded integrally with the supporting structure 28, the entire set of nails is rendered relatively easy to manufacture and to handle for subsequent packaging and use.

[0040] When it is desired to attach the artificial nails 10, the user may first select the desired nail size based on the indicia 64 shown on each nail's respective release tape 62. The user may then grasp the nail body 12 of the selected nail 10 between the thumb and forefinger and easily detach the nail from the supporting structure 28. In this regard, the supporting structure 28 preferably includes a frangible or breakable stem 30 connected to the proximal end 16 of each nail body 12, which enables the nails 10 to be manually snapped off the tree without damaging the nail bodies 12.

[0041] Once the nail is removed from the tree, the release tape is removed to reveal the pressure sensitive adhesive. The adhesive side of the nail is then positioned on the natural nail and, with slight pressure, the nail can be conveniently fixed to the natural nail.

[0042] While there has been described what is presently believed to be the preferred embodiments of the invention, those skilled in the art will realize that various changes and modifications may be made to the invention without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as fall within the scope of the invention.
