Description

Artificial nails with size indication

The invention relates to an artificial nail applied to a natural nail by an adhesive, and particularly to an artificial nail with a size mark to help select and apply an artificial nail of an appropriate size to the natural nail.

Artificial nails have been used for many years to enhance the aesthetics of fingers. Some people choose to use artificial nails because their nails are too fragile to keep the nails to the ideal length without breaking. Some people choose artificial nails because they are stronger and more durable than natural nails, and because nail polish adheres better to the surface of artificial nails. Some people choose artificial nails to improve the appearance of their nails because they are not satisfied with the shape and contours of their nails.

In the conventional art of hand decoration, a decorative nail accessory made of a thin molded plastic member made in the shape of a nail is usually provided. Indeed, many artificial nail manufacturers have provided nail accessories with a combination of materials, arrangements, and colors. For example, many conventional pre-designed nails often include decorative designs that are printed or sprayed on the upper surface.

With the advent of such artificial nail accessories, wearers have been able to attach complex, pre-designed artificial nails to natural nails and easily remove them later. The pre-designed artificial nail is generally adhered to the surface of the natural nail by applying a certain amount of liquid adhesive on the bottom surface of the artificial nail and / or the upper surface of the natural nail. In this case, the wearer must wipe or trim the excess adhesive, and then wait a few minutes until the adhesive is dry to ensure that the accessory is fixed on the nail. A cover layer is then usually applied to the entire upper surface of the artificial nail. The cover layer is usually transparent or translucent so that the decorative design of the upper surface of the artificial nail can be seen. Once the cover layer has set, the artificial nail is formed as expected.

However, one of the disadvantages of artificial nails is that the application process can be tedious and cumbersome. In particular, when attaching artificial nails, you must hold the artificial nails and apply glue to the bottom surface, and then flip the artificial nails so that the bottom of the cloth is facing down, so that the artificial nails are positioned on the natural nails. When the artificial nails are placed correctly A slight pressure must be applied to the glue to fully fix the artificial nails to the natural nails. During this entire process, the artificial nails are continuously held between the fingers of the opposite hand, so the applied glue often comes into contact with the fingers, which not only adversely changes the adhesive properties of the glue, but also makes the treatment of artificial nails It becomes difficult, and removing the glue on the fingers between applying each artificial nail also makes the process more time consuming.

In U.S. Patent No. 6,892,736 to Chang (the inventor of the present case) and others, a prior art attempt to mitigate these processing problems is disclosed. The patent is an artificial nail for attaching to a natural nail, which includes a nail body having a proximal end and a distal end opposite to the proximal end. The size and shape of the proximal end are suitable for attachment. On the upper surface of natural nails. An application tag extends outward from the distal end of the nail body, and the application tag is adapted to be grasped during the attachment of the nail body to the natural nail.

Another prior art solution to this problem is disclosed in U.S. Patent No. 8,528,570 to the inventor of the present case, Chang. The patent relates to a disposable artificial nail, which includes a nail body, and a pressure-sensitive adhesive is arranged on the lower side of the nail body. In use, before applying the nail body, remove and cover one of the pressure-sensitive adhesive peeling tapes to expose the adhesive layer, and press the nail body on the natural nail to fix the artificial nail to it. on. The release tape is provided with a holding tab, and the holding tab can be held in order to remove the release tape from the pressure-sensitive adhesive.

Although these patents disclose solutions to the problem, there are also problems in selecting and applying artificial nails of appropriate size on natural nails. Because nail sizes vary from person to person, it is almost impossible to design a single artificial nail that generally fits each nail.

To solve this problem, there are existing artificial nail sets that provide multiple artificial nails of different sizes. For example, in a typical artificial nail combination, two or more different sizes may be provided for each finger, either on the nail body or on the application label (see Chang et al. Above). U.S. Patent No. 6,892,736).

However, one of the disadvantages of providing size marks on the nail body is that after applying artificial nails to natural nails, the size marks are still visible, resulting in an undesirable appearance. Even if the size label is set on the removable application label, there are still defects such as the complexity and cost of additional special design molds, including the preparation of the mark in the nail body during the plastic injection molding process. In other cases, the markings molded into the nail body or application label are often difficult to see before the product is applied.

Accordingly, it is desirable to provide an artificial nail that does not have the above disadvantages and is easy to apply to natural nails. In addition, it is also desirable to provide artificial nails inexpensively with clearly visible size markings.

The invention relates to an artificial nail for attaching to a natural nail, comprising: a nail body, the nail body having a bottom surface, the size and shape of the bottom surface are suitable for being attached to the upper surface of the natural nail; a pressure-sensitive type The adhesive is disposed on the bottom surface of the nail body; and a peelable backing film is covered on the pressure-sensitive adhesive, wherein the peelable backing film includes a mark indicating the size of the nail body.

In a preferred embodiment, the peelable backing film includes a label tab extending beyond an edge of the nail body to facilitate removing the peelable backing film from the pressure-sensitive adhesive, wherein The mark is disposed on the label tab.

The mark may be formed by a plurality of lines cut into the peelable backing film, or may be printed on the peelable backing film. The pressure-sensitive adhesive and the peelable backing film may include a plurality of cutting lines forming through the pressure-sensitive adhesive and the peelable backing film. Preferably, the mark further indicates a curvature of the nail body.

In another aspect, the present invention provides an artificial nail set for attaching to a natural nail. The artificial nail set usually includes a plurality of nail bodies of different sizes, each of which has a bottom surface, and the size and shape of the bottom surface are suitable for being attached to the upper surface of a natural nail of a corresponding size. The artificial nail set further includes a pressure-sensitive adhesive provided on the bottom surface of each of the nail bodies, and a peelable backing film covering the pressure-sensitive adhesive on each of the nail bodies, wherein, The peelable backing film of each nail body includes a mark indicating the size of the nail body to which it is attached. Further, the artificial nail set includes a supporting structure, and the supporting structure includes a plurality of fragile rods, each of which is detachably connected to the nail body for temporarily supporting the nail body.

"Artificial nails" as used in this article also includes nail extensions, which are called "tips" in business. Therefore, the artificial nail may be a full nail cover, in which the size and shape of the proximal end of the nail body is designed to substantially correspond to a complete nail bed of natural nails; or the artificial nail may be a nail tip, The size and shape of the proximal end of the nail body are designed to be connected only to the distal end of a natural nail.

Therefore, the present invention provides an artificial nail that has a cheap application and has a mark that is easily visible by nail size.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, and other objects and features of the present invention will become apparent. However, it should be understood that the drawings are only used to clarify the features and applications of the invention, but not to limit the scope of the invention.

Please refer to FIG. 1 and FIG. 2 together, which are artificial nails 10 of conventional techniques. In each case, the artificial nail 10 includes a one-piece molded nail body 12 having a distal end 14 and a proximal end 16 opposite the distal end 14. The proximal end 16 (more specifically, adjacent to the bottom surface of the proximal end 16) is sized and shaped to be attached to the upper surface of a natural nail. The size of the distal end 14 may be designed such that when the artificial nail is attached to the natural nail, the end of the artificial nail extends beyond the end of the natural nail, or may be designed to coincide with the end of the natural nail.

The nail body 12 may be round or straight, and is not limited to any particular size. In other words, the artificial nail 10 can be applied to nails and / or toenails, and can be made in various sizes and shapes. For example, the size and shape of the proximal end 16 of the nail body 12 can basically correspond to the complete nail bed of natural nails, so those who apply the proximal end 16 of the nail body 12 to the complete nail bed of natural nails are called full nails. Nail covering sheet; or, the proximal end 16 of the nail body 12 is only attached to the distal end of the natural nail, ie, for example, its size and shape may correspond to only the distal end of the natural nail bed, so the nail body 12 should The proximal end 16 applied to the end of a natural nail is called a nail (or half nail). However, once applied properly, it is often difficult to distinguish nails from full nail covers.

FIG. 2 is an example of an artificial nail disclosed in US Patent No. 6,892,736, which is commonly owned by the inventor Chang et al. In this embodiment, an application tag 18 extends outward from the distal end 14 of its nail body 12 and is adapted to be grasped between the thumb and index finger to help attach the artificial nail 10 to a natural nail. The application tag 18 generally includes a frangible portion 20 adjacent to the distal end 14 of the nail body 12. The frangible portion 20 is used to separate the application tag 18 from the nail body 12 at a separation line 22.

As described above, the conventional technique is to set a mark 24 on the nail body 14 (as shown in FIG. 1) or on the application label 18 (as shown in FIG. 2) to indicate the size of the artificial nail 10. The mark 24 is generally molded or etched into the nail body 12 or the application label 18. However, when molded into the nail body 12 or the application label 18, it is often difficult to see the mark 24 before the artificial nail 10 is applied. As a result of improving the visibility of the indicia 24, the indicia 24 can only be seen after the artificial nail 10 is applied to natural nails, which results in an undesirable aesthetic appearance. Even if the mark 24 is provided on the removable application label 18, there is still the complexity and cost of an extra specially designed mold that includes the mark 24 for forming the mark 24 on the nail body 12 during the plastic injection molding process.中 的 装置。 In the device.

Please refer to FIG. 3 and FIG. 4 together, and one of the artificial nails 50 shown therein solves these problems. 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 nail body 52 having a distal end 54 and a proximal end 56 relative to the distal end 54, wherein the proximal end 56 (more specifically, adjacent to the The bottom surface 58) of one of the proximal ends 56 is sized and shaped to be attached to the upper surface of a natural nail.

However, according to the present invention, the bottom surface 58 is provided with a pressure-sensitive adhesive 60 and a peelable backing film 62 covering the pressure-sensitive adhesive 60. The peelable backing film 62 is used for The artificial nail 50 protects the pressure-sensitive adhesive 60 before being applied to a natural nail. A mark 64 indicating the size of the artificial nail 50 is provided on the peelable backing film 62. Preferably, the mark 64 is provided on a label tab 66 of the peelable backing film 62, as shown in FIG. 3; or, the mark 64 may be provided on any of the peelable backing film 62. Elsewhere so that the mark 64 can be seen from the underside of the nail.

In a modification of the present invention, as shown in FIG. 5, the artificial nail may also have the features disclosed in US Patent No. 8,528,570, which is jointly owned by the inventor of the present case, Chang. In this example, a one-touch artificial nail according to the present invention generally includes an artificial nail unit 200. The artificial nail unit 200 has a nail body 210, and is used to attach the artificial nail unit 200 to A double-sided adhesive tape body 110 for a natural nail and a peelable adhesive tape 120. A first cutting line 114 and a second cutting line 124 are respectively formed on the double-sided tape body 110 and the peelable tape 120. The first cutting line 114 and the second cutting line 124 are formed to penetrate through the double-sided tape body 110 and the peelable tape 120, respectively.

Therefore, when the double-sided tape body 110 and the peelable tape 120 having a flat shape are attached to the nail body 210 having a curved shape, air located between the nail body 210 and the double-sided tape body 110 passes through the first A cutting line 114 and the second cutting line 124 are discharged. Further, since the first cutting line 114 and the second cutting line 124 are formed in a line shape, the rigidity of the double-sided tape body 110 can be maintained. In other words, during the process of detaching the release tape 120 from the double-sided tape body 110, the double-sided tape body 110 can be prevented from being torn. In addition, since the area of the peelable tape 120 is larger than the area of the double-sided tape body 110, impurities can be prevented from adhering to the double-sided tape body 110.

The nail body 210 includes a distal end 211 located on the free edge side of the artificial nail unit 200, a proximal end 213 located on the cuticle (also known as carpel, nail skin) side of the artificial nail unit 200, One side end 215 and an adhesive surface 219 formed at a position facing the natural nail. The double-sided tape body 110 includes a plurality of non-connected portions formed by cutting a plurality of the first cutting lines 114 and a plurality of connecting portions 112 a formed between the plurality of the first cutting lines 114 so that the plurality of The non-connected parts are not separated from each other.

The release tape 120 has an area larger than that of the double-sided tape body 110, and the double-sided tape body 110 is attached to an upper portion of the release-type tape 120 so that the double-sided tape body 110 does not deviate from the release-type tape 120. Preferably, the peelable tape 120 further includes a holding portion 122 connected to the outer periphery of the distal end 211 of the nail body 210 and protruding from the outer periphery.

The peelable tape 120 may be made of polyethylene (PE), ethylene-vinyl acetate copolymer (EVA), polypropylene (PP), or polyolefin elastomer (Polyolefin Elastomer) POE), and any one of polyethylene terephthalate (Polyethylene terephthalate, PET for short) or a copolymer or blend thereof. In addition, the release tape 120 preferably has a tensile strength of 5 kg / cm ² or higher. When the release tape 120 is made of the above materials, the thickness of the release tape 120 is preferably 30 μm to 300 μm.

Preferably, the thickness of the double-sided tape body 110 is 150 μm to 800 μm. Preferably, the peel strength of the double-sided tape body 110 is 300 gf / 10 mm or higher. The double-sided tape body 110 applied to the one-touch artificial nail of the present invention may be provided as a single layer or a laminated structure of a plurality of layers.

As described above, a mark 164 indicating the size of the nail body 210 is provided on the peelable tape 120. Preferably, the mark 164 is provided on the holding portion 122, but may also be provided at any other position on the peelable tape 120. The mark 164 may be a cutting line formed during a printing or cutting process for manufacturing the release tape 120. Specifically, the printing or cutting die used to form the release tape 120 may include a raised portion to emboss or cut the mark 164 in the release tape 120. Alternatively, the indicia 164 may be printed on the release tape 120 in a subsequent printing process, or may be applied in other ways using any known technique.

The mark (64, 164) can indicate the size of the nail body (52, 210) in terms of width, for example, a size recognized from the industry ranging from # 1 (largest) to # 15 (smallest). Or, preferably, the mark (64, 164) can indicate the size of the nail body (52, 210) in terms of the lateral and / or vertical curvature of the nail. For example, it has been found that since the lateral and longitudinal curvatures of natural nails vary from person to person, it is better to provide artificial nails that can adapt to these changes. Therefore, artificial nails can have lateral curvature, which ranges from extra flat (EF), flat (F), regular (R), high (H) to extra high high, referred to as EH). Similarly, artificial nails may have a longitudinal curvature of medium (M for short) and curved (C for short). In this method, a # 5 width artificial nail with a flat lateral curvature and a medium longitudinal curvature will include a peelable tape with an "F-M # 5" mark, as shown in FIG. 2.

FIG. 6 is a typical artificial nail set 26 composed of a plurality of artificial nails 10 according to the present invention. Preferably, the artificial nail set 26 is an integral part made by injection molding, and the integral part includes a plurality of spaced-apart artificial nails 10 connected to a support structure 28 (like a trunk that becomes a center). Each artificial nail 10 includes a nail body 12, a pressure-sensitive adhesive (not shown) disposed on the lower side of the artificial nail 10, and a peelable backing film 62 covering the pressure-sensitive adhesive. . In this embodiment, the peelable backing film 62 of each artificial nail 10 includes a label tab 66 having a mark 64 so that a user can easily see the artificial nail 10 Individual sizes. As shown in FIG. 6, the mark 64 of each artificial nail 10 is different. Preferably, the plurality of artificial nails 10 are arranged on the supporting structure 28 in a beautiful and functional pattern. In particular, the artificial nails 10 are preferably arranged in order of size and side by side along the supporting structure 28. Since all the artificial nails 10 are integrally molded with the support structure 28, it is relatively easy to manufacture and process the entire artificial nail set 26 for subsequent packaging and use.

When the artificial nail 10 needs to be attached, the user first selects a desired nail size according to the mark 64 shown on the peelable backing film 62 of each artificial nail 10, and then can be between the thumb and forefinger The nail body 12 of the selected artificial nail 10 is held, and the artificial nail 10 is easily separated from the support structure 28. In this regard, the support structure 28 preferably includes a frangible rod 30 connected to the proximal end 16 of each nail body 12 so that the artificial nail 10 can be manually broken from the support structure 28 without damaging the nail body 12 .
