Description

  The present invention generally relates to an artificial nail that adheres to a natural nail using an adhesive, and more specifically, an artificial nail having an appropriate size is selected and a size display that makes the selected artificial nail easily adhere to a natural nail. Related to nails.

  Artificial nails have been used for a long time to improve the cosmetic appearance of fingers. Some people use artificial nails because their nails are too weak to grow to the desired length without breaking. Others use artificial nails because artificial nails are much stronger and longer lasting than natural nails and because nail polish adheres better to the surface of artificial nails. Some people do not like the shape and contours of their natural nails and use artificial nails to improve the appearance of their nails.

  In the field of hand decoration, it is well known to provide decorative nail accessories with thin plastic members that are generally manufactured by molding into nail shapes. In fact, a great many artificial nail manufacturers have provided various materials, arrangements, and hue combinations in nail accessories. For example, many conventional pre-designed nails often include a decorative pattern formed on the top surface by stencil processing or air brush processing.

  With the advent of such artificial nail accessories, the user can design in advance a nail that adheres to the natural nail in advance and easily remove it later. The pre-designed artificial nail is generally attached to the surface of the natural nail by applying a liquid adhesive to the bottom surface of the artificial nail and / or the top surface of the natural nail. In this way, the accessory is attached to the nail. In this case, the user must wait several minutes for the adhesive to dry after the excess amount of adhesive has been wiped off or trimmed away so that the accessory can be secured to the nail. Thereafter, an overlay is generally placed over the entire top surface of the artificial nail. In general, the top cover is transparent or translucent so that the decorative design on the top surface of the artificial nail is visible. If the top cover is arranged, the artificial nail has a desired shape.

  However, one drawback of artificial nails is that the adhesion process is cumbersome and dirty. In particular, when attaching an artificial nail, it is necessary to apply an adhesive to the bottom surface of the nail while the artificial nail is picked. Thereafter, the artificial nail must be covered so that the bottom surface to which the adhesive is applied faces downward, and the artificial nail must be positioned on the natural nail. If the artificial nail is properly positioned, a little pressure must be applied to the nail so that the artificial nail is sufficiently secured to the natural nail by the adhesive. Since all of these processes are performed, the artificial nail is maintained in a state of being fixed between the fingers of the other hand, so that the adhesive applied to the artificial nail is often attached to the finger. As a result, not only does the adhesive properties of the adhesive change unfavorably, but handling of the artificial nail becomes difficult. The process takes longer because the adhesive must be removed from the finger each time the nail is applied.

  An example of prior art to alleviate such handling problems is disclosed in US Pat. No. 6,892,736 granted to Chang et al. This patent is an artificial nail for attaching to a natural nail, comprising an nail body having a proximal end and a distal end facing the proximal end of a size and shape that can be attached to the upper surface of the natural nail Is disclosed. An application tab configured to be gripped while the nail body is attached to the natural nail extends outwardly from the distal end of the nail body.

  Another example of the prior art for solving such handling problems is disclosed in US Pat. No. 8,528,570 granted to Chang. U.S. Pat. No. 8,528,570 granted to Chang discloses a one-touch artificial nail comprising a nail body having a pressure sensitive adhesive disposed on its underside. When in use, the peeling tape that covers the pressure-sensitive adhesive and protects the pressure-sensitive adhesive before adhesion is removed, exposing the adhesive layer, and pressing the nail body on the natural nail will fix the artificial nail to the natural nail The The release tape is provided with a handling tab that is picked to easily remove the release tape from the adhesive.

  Although these patents disclose solutions to handling problems, there are still problems associated with selecting an appropriately sized artificial nail and attaching the selected artificial nail to a natural nail. Since the size of the nail varies from person to person, it is virtually impossible to design a single artificial nail that universally fits all nails.

  In order to solve such a problem, an artificial nail set including a large number of artificial nails having various sizes is provided. For example, a typical artificial nail package can provide two or more different sizes of artificial nails for each finger. In this case, an indication of the size of each nail is provided on the nail body, or on the application tab disclosed in US Pat. No. 6,892,736 granted to Chang et al. Provided.

  However, one drawback caused by providing a size display on the nail body is that the display is still noticeable after the artificial nail is attached to the natural nail and the appearance is not aesthetically pleasing. Even when the size indication is provided on a removable application tab, the configuration is more complicated by a specially designed mold to form the indication in the nail body during the plastic injection molding process Still, the problem of increasing costs still exists. In other situations, the markings formed on the nail body or application tab by molding are often difficult to see prior to product attachment.

  Therefore, it is preferable to provide an artificial nail that can easily adhere to a natural nail while not having the above-described drawbacks. It is also preferred to provide a clearly visible size indication for the artificial nail at a low cost.

  The present invention relates to an artificial nail for attaching to a natural nail, a nail body having a bottom surface of a size and shape that can be attached to the top surface of the natural nail, and a bottom surface of the nail body. And a peelable backing film covering the pressure sensitive adhesive, the peelable backing film comprising an artificial nail having an indication of the size of the nail body Have.

  In one preferred embodiment, the peelable backing film extends beyond the edge of the nail body so that the peelable backing film can be easily removed from the pressure sensitive adhesive. tab portion) and the display is provided on the tab portion.

  The indicia can be formed by lines cut into the peelable backing film or printed on the peelable backing film. The pressure sensitive adhesive and the peelable backing film may include cutting lines penetrating the pressure sensitive adhesive and the peelable backing film. More preferably, the display indicates the curvature (curvature) of the nail body.

  According to another aspect of the present invention, an artificial nail set for attaching to a natural nail is provided. Generally, an artificial nail set includes a plurality of nail bodies having different sizes. The nail body includes a bottom surface having a size and a shape that can be attached to the top surface of a natural nail having a corresponding size. The artificial nail set includes a pressure-sensitive adhesive placed on the bottom surface of each nail body and a peelable backing film covering the pressure-sensitive adhesive of each nail body, and each nail body can be peeled off The backing film is provided with an indication that indicates the size of the nail body to which the peelable backing film is attached. Also, a support structure including a plurality of fragile trunks (stems) is provided, and each trunk is detachably connected to the nail body to temporarily support the nail body at the upper part.

  As used herein, “artificial nails” also include nail extensions called “tips” at the time of sale. Thus, the artificial nail can be full cover. In this case, the proximal end of the nail body has a size and shape substantially corresponding to the full nail bed of the natural nail. In contrast, an artificial nail can be a nail tip. In this case, the proximal end of the nail body has a size and shape that can only be attached to the distal end of the natural nail.

  According to the present invention, an artificial nail that can be attached at a low cost and is easy to see the size display of the nail is provided.

  Other objects and features of the present invention will become apparent from the following detailed description when taken in conjunction with the accompanying drawings. However, it should be understood that the accompanying drawings are provided for illustrative purposes only and do not limit the present invention.

1 is a top perspective view of an artificial nail having a size indication (indicia) according to the prior art; FIG. FIG. 6 is a top perspective view of an artificial nail having a size indication on an application tab according to the prior art. It is a bottom view of an artificial nail having a size display according to the present invention. It is a bottom view of the other Example of the artificial nail which has the size display by this invention. It is a disassembled perspective view of further another embodiment of the artificial nail according to the present invention. FIG. 4 is a top perspective view of an artificial nail set including artificial nails of different sizes according to the present invention as shown in FIG. 3.

  1 and 2 show an artificial nail 10 according to the prior art. In each case, the artificial nail 10 includes an integrally molded body 12 with a distal end 14 and a proximal end 16 facing the distal end. The proximal end 16 and particularly the bottom surface adjacent to the proximal end has a size and shape that can be attached to the top surface of the natural nail. The distal end 14 can have a size that extends beyond the end of the natural nail when the artificial nail is attached to the natural nail or a size that matches the end of the natural nail.

  The nail body 12 may be formed in a round shape or a straight line, and the size of the nail body 12 is not particularly limited. In addition, the artificial nail 10 can be attached to the nail of the hand and / or the toenails and can have various sizes and shapes. For example, the proximal end 16 of the nail body 12 can correspond in size and shape to the bottom of the entire nail of a natural nail. Therefore, the artificial nail can be referred to as a full nail cover attached over the bottom surface of all nails of the natural nail. In contrast, the proximal end 16 can only be attached to the distal end of the natural nail. That is, for example, the proximal end 16 can correspond in size and shape only to the distal end of the bottom of the natural nail. Thus, the artificial nail can be called a nail tip attached to the end of the natural nail. However, once properly attached, it is often difficult to distinguish the tip from the cover.

  FIG. 2 shows one embodiment of an artificial nail disclosed in US Pat. No. 6,892,736 granted to Chang et al. In this embodiment, the application tab 18 extends outwardly from the distal end 14 of the nail body 12 and is easily pinched between the thumb and index finger so that the artificial nail 10 is easily attached to the natural nail. It is configured as follows. The application tab 18 is generally disposed adjacent the distal end 14 of the nail body 12 and includes a fragile portion 20 for separating the application tab from the nail body along a separation line 22.

  As described above, it is well known in the technical field to which the present invention belongs to provide an indication 24 indicating the size of the nail 10 on the nail body shown in FIG. 1 or on the application tab shown in FIG. Yes. The display 24 is typically formed in the nail body 12 or application tab by molding or etching. However, when the display is formed in the nail body or the application tab by molding, it often happens that the display is difficult to see in the nail attached in advance. Many efforts have been made to improve the visibility, but the appearance is not preferable from the aesthetic viewpoint because the display is conspicuous even after the artificial nail is attached to the natural nail. Even when the size indication is provided on a removable application tab, the configuration is more complicated by a specially designed mold to form the indication in the nail body during the plastic injection molding process Still, the problem of increasing costs still exists.

  3 and 4, an artificial nail 50 that solves such a problem is shown. The artificial nail 50 according to the present invention is similar in many respects to the artificial nail 10 described with reference to FIGS. For example, the artificial nail 50 includes a body 52 formed into a one-piece with a distal end 54 and a proximal end 56 facing the distal end. Proximal end 56 and in particular bottom surface 58 adjacent to the proximal end are sized and shaped to allow attachment to the top surface of the natural nail.

  However, according to the present invention, a pressure sensitive adhesive 60 is applied to the bottom surface 58, and a peelable backing film 62 is adhered over the entire pressure sensitive adhesive. And protects the adhesive before the artificial nail is attached. An indication 64 indicating the size of the artificial nail 50 is provided on the peelable backing film 62. An indication 64 is preferably provided on the tab portion 66 of the backing film, as shown in FIG. Alternatively, the display 64 can be provided at any other position on the backing film 62 so that it can be seen from the bottom side of the nail.

  In the case of the variation of the present invention shown in FIG. 5, the artificial nail may also have the features disclosed in US Pat. No. 8,528,570 shared by Chang. Here, the one-touch artificial nail according to the present invention generally includes an artificial nail unit 200 having a nail body 210, a double-sided adhesive tape body 110 used to attach the artificial nail unit 200 to the nail, a release tape (release). tape) 120). The 1st cutting line 114 and the 2nd cutting line 124 are formed in the double-sided adhesive tape body 110 and the peeling tape 120, respectively. The 1st cutting line 114 and the 2nd cutting line 124 are penetrated by the double-sided adhesive tape body 110 and the peeling tape 120, respectively.

  Therefore, when the double-sided adhesive tape body 110 having a flat shape and the peeling tape 120 are attached to the nail body 210 having a curved shape, the air positioned between the nail body 210 and the double-sided adhesive tape body 110 is the first cutting line. 114 and the second cutting line 124. Furthermore, since the 1st cutting line 114 and the 2nd cutting line 124 are formed so that it may have a linear shape, the rigidity of a double-sided adhesive tape can be maintained. In addition, when the peeling tape 120 is separated from the double-sided adhesive tape body 110, the double-sided adhesive tape body 110 can be prevented from being broken. Moreover, since the area of the peeling tape 120 is larger than the area of the double-sided adhesive tape body 110, it is possible to prevent impurities from attaching to the double-sided adhesive tape.

  The nail body 210 faces the distal end 211 located at the free edge of the artificial nail, the proximal end 213 located at the nail cuticle, the side 215, and the nail. And an adhesive surface 219 formed at the position. The double-sided adhesive tape body 110 is formed between a plurality of unconnected portions formed by cutting the plurality of first cutting lines 114 and the first cutting lines 114 so that the plurality of unconnected portions are not separated from each other. And a connecting portion 112a.

  The peeling tape 120 has a larger area than the double-sided adhesive tape body 110, and the double-sided adhesive tape body is attached to the upper part of the peeling tape 120 so that the double-sided adhesive tape body 110 is not detached from the peeling tape 120. The peeling tape 120 is preferably connected to the outer peripheral surface of the one end portion 211 of the nail body 210, and further includes a knob (grip) 122 protruding therefrom.

The release tape 120 may be manufactured from any one of PE, EVA, PP, POE, and PET, or copolymers or blends thereof. The release tape 120 preferably has a tensile strength of 5 kg / cm ² or more. When the release tape 120 is manufactured from the material described above, the thickness of the release tape is preferably 30 μm to 300 μm.

  The double-sided adhesive tape body 110 is preferably formed to have a thickness of 150 to 800 μm. The peel strength of the double-sided adhesive tape body 110 is preferably 300 gf / 10 mm or more. In the one-touch artificial nail according to the present invention, the double-sided adhesive tape body 110 may be formed of a single layer or a stacked structure in which a plurality of layers are stacked.

  As described above, an indication 164 indicating the size of the nail is provided on the release tape 120. Indicia 164 is preferably provided on knob 122, but can be provided at any other location on release tape 120. The display 164 may be formed as a plurality of cutting lines while performing a stamping process or a cutting process for manufacturing a release tape. In particular, stamping dies or cutting dies used to form the release tape can include raised portions for impressing or cutting the display in the release tape. In contrast, the indicia 164 can be printed on a release tape during a subsequent printing process, or otherwise formed by any known technique.

  The display 64 and the display 164 can indicate the sizes of the nail body 52 and the nail body 210 in terms of width. For example, industrially applicable sizes from # 1 (maximum) to # 15 (minimum) can be indicated. In contrast to this, or in addition thereto, the display 64 and the display 164 can indicate the sizes of the nail body 52 and the nail body 210 in terms of curvature in the width direction and / or longitudinal direction of the nail. For example, since natural nails have different curvatures (curvatures) in the width direction and the longitudinal direction for each person, it has been found that it is preferable to provide an artificial nail that can cope with such differences. Therefore, the nail can have a curvature in the width direction which is divided into an extra flat (EF), a flat (F), a regular (R), a high (H), and an extra high (EH). Thus, the nail can have a curvature in the longitudinal direction of the medium (M) and the curve (C). Thus, the # 5 width claw, which has a flat curvature in the width direction and a medium curvature in the longitudinal direction, has a display indicating "F-M # 5" as shown in FIG. A release tape can be included.

  FIG. 6 illustrates a typical artificial nail set 26 made of the artificial nail 10 formed according to the present invention. The artificial nail set 26 is formed as a unitary part including a plurality of artificial nails 10 of different sizes spaced apart from each other and connected to a support structure 28 such as a central tree by injection molding. Preferably it is manufactured. Each artificial nail 10 includes a nail body 12, a pressure sensitive adhesive (not shown) applied to the underside of the nail, and a release tape 62 covering the pressure sensitive adhesive. In this embodiment, an indicator 64 is provided on the tab 66 of the release tape 62 of each nail so that the user can easily see the size of each nail. As shown in FIG. 6, the display 64 is different for each nail. The artificial nails 10 are preferably arranged on the support structure 28 in a functional pattern while being aesthetically pleasing. In particular, the artificial nails 10 are preferably arranged in order of size, and are preferably arranged side by side along the support structure 28. Since all the artificial nails 10 are molded integrally with the support structure 28, the entire nail set is relatively easy to manufacture and is relatively easy to handle in subsequent packaging and use stages.

  When the artificial nail 10 is to be attached, the user can first select a desired nail size by the display 64 displayed on the peeling tape 62 of each nail. Thereafter, the user can easily pick the nail body 12 of the selected artificial nail 10 between the thumb and forefinger and easily separate the artificial nail from the support structure 28. In this regard, the support structure 28 preferably includes a fragile or fragile stem 30 connected to the proximal end 16 of each pawl body 12. By providing such a trunk, the user can fold the artificial nail 10 from the central tree without damaging the nail body 12 by hand.

  Once the artificial nail is removed from the center tree, the release tape is removed to expose the pressure sensitive adhesive. Then, the adhesion surface of the artificial nail is positioned on the natural nail, and the artificial nail can be conveniently fixed to the natural nail by applying a little pressure.

  As described above, the preferred embodiments of the present invention have been described. However, a person having ordinary knowledge in the field to which the present invention belongs can be variously modified and modified without departing from the spirit of the present invention. I understand that. All such changes and modifications should be construed as being included within the scope of the present invention.
