  The present invention is a connector that has a strong adhesive force that allows repeated application and peeling of a decorative nail chip to a nail and can be used repeatedly. The present invention relates to an adhesive sheet for a nail chip which is strengthened and can be easily cut without extending during use like a normal adhesive sheet.

  Nail art, which is colored with nail polish on nails of limbs and decorated three-dimensionally with acrylic resin etc., has attracted a lot of attention mainly by women, and various treatments related to the nail art Many nail salons to be run are also managed. Basically, nail art is intended for users to perform desired treatments at the nail salon and decorate their nails, but in recent years there are many women who balance work and housework. In many cases, the user himself applies simple nail art at an arbitrary timing using commercially available nail goods.

  Among these, nail tips are popular as users can enjoy full-fledged nail art relatively easily, and users can attach and peel off commercially available nail tips at any timing. There are many methods for attaching a nail chip to a nail, but the inventors are a connector having a strong adhesive force that allows a decorative nail chip to be repeatedly applied to a nail and peeled off. We provide a double-sided adhesive sheet for nail chips that can be used repeatedly even if dust or the like adheres to the adhesive surface with a strong force and the adhesive force is reduced. (See Patent Document 2).

  However, in the adhesive sheet for the nail chip, the adhesive material on the adhesive surface has a strong adhesive force, and once it is attached to the nail, the adhesive material will be stretched and pulled when peeled off. there were. In addition, when the sheet is cut in accordance with the user's nails, there is also a problem that the cutting material is attached to the cutting tool and the workability is poor.

  The present invention has been created in view of the above problems, and the present invention is a decorative nail tip that can be used repeatedly while having a strong adhesive force to a nail, and adds a predetermined aggregate. Thus, an object of the present invention is to provide an adhesive sheet for nail chips that has high workability at the time of cutting without extending at the time of peeling or use like a normal adhesive sheet.

  The present invention is an adhesive sheet for a nail chip that is attached between an inner surface of a nail chip and a user's nail and adheres both, and includes at least one thermoplastic elastomer (TPE), a tackifier, and a softening agent. 2 or more pressure-sensitive adhesive layers (for example, the pressure-sensitive adhesive sheet 2 in the embodiment), and a sheet-like aggregate having porosity in the thickness direction and interposed between the pressure-sensitive adhesive layers, It is characterized by.

  The adhesive sheet for a nail chip of the present invention has a pressure-sensitive adhesive layer that can be applied to and removed from the nail while ensuring strong adhesiveness by containing a predetermined material, and is in the form of a sheet between the adhesive layers Compared to the case of only the adhesive layer, the adhesive material sticks to the cutting tool at the time of cutting without causing any trouble in handling when it peels off from the nail or is used compared to the case of only the adhesive layer. This is advantageous in that the workability is not deteriorated. When sheet-like aggregate is inserted into the adhesive layer, the aggregate regulates the expansion and contraction of the adhesive layer.

  In particular, since the adhesive layer is formed of a material having pores, it is advantageous in that the extension is restricted for each pore, and as a result, the adhesive layer as a whole is prevented from extending in the planar direction. Further, even if the adhesive layer is locally crushed in the thickness direction at the time of cutting, the adhesive material that protrudes into the pores does not stick to the cutting tool and the workability does not deteriorate.

  The aggregate is formed of a woven structure or a non-woven structure. In the case of a woven structure, it is a porous structure of a set of regular frames and holes surrounded by the frames, and is typically preferably formed in a mesh structure. Moreover, you may form the said aggregate with a nonwoven fabric structure.

  Moreover, it is preferable that the said adhesion layer contains 100 weight part of at least 1 type of thermoplastic elastomer (TPE), 300-500 weight part of tackifiers, and 100-150 weight part of softening agents.

  By adjusting the distribution by including the above components in the adhesive layer, it is easy to attach the nail chip to the nail, and it is also possible to remove the nail chip from the nail without using a separate chemical, etc. Even if the adhesive strength is reduced, the adhesive strength is restored by washing with water or a neutral detergent, and can be repeatedly used for attaching a nail chip.

  Further, in the adhesive sheet for nail chip, the thermoplastic elastomer is mainly composed of styrene elastomer (TPS), the tackifier is selected from the group consisting of aliphatic hydrocarbon resins, and the softener is It is preferably a petroleum softener.

  Moreover, it is preferable that the said adhesion layer contains a water-soluble thickener.

  When a water-soluble thickener is added to the adhesive layer, the adhesive strength increases due to the water-soluble thickener generated when water is absorbed. The fixing force can be maintained.

  Furthermore, the water-soluble thickener is contained in an amount of 5 to 20% of the component of the adhesive surface of the adhesive sheet for nail chips. Specifically, gelatin, agar, pectin, carrageenan, guar gum, xanthan gum, tamarind gum, propylene It is preferable that glycol, carboxymethyl cellulose, acrylic polymer, or polyacrylamide polymer is the main component.

  According to the adhesive sheet for a nail chip of the present invention, while having a sticky layer that can be applied to and removed from the nail while ensuring strong tackiness by containing a predetermined material, between the sticky layers Compared to the case of only the adhesive layer by inserting sheet-like aggregate, it does not cause trouble in handling when it is peeled off from the nail or used, and the cutting tool has an adhesive material when cutting. This is advantageous in that the workability does not deteriorate due to sticking.

  Hereinafter, a typical embodiment of an adhesive sheet for a nail chip according to the present invention will be described in detail with reference to FIGS. 1 to 10, but it goes without saying that the present invention is not limited to this embodiment. . Further, each drawing is for conceptually explaining the present invention, and there are cases where dimensions, ratios or numbers are exaggerated or simplified as necessary for easy understanding. Further, in the following description, the same or corresponding parts are denoted by the same reference numerals, and redundant description may be omitted.

  Then, the design and shape of the nail tip 3 are determined according to the desire of the model. Thereafter, the practitioner measures the size and shape of the model nail using a measuring instrument used for the nail called a scale tip, and determines the size of the nail tip 3 used for the model nail. Basically, the nail tip 3 has a size that is slightly larger than the nail of the model. However, in the case of a nail with a large curvature or a flat nail, it is desirable to use a nail tip 3 that is slightly smaller in size.

  Then, the treatment procedure of the nail chip 3 using the nail chip adhesive sheet 1 and the configuration of the nail chip adhesive sheet 1 will be described below. FIG. 1 is a schematic diagram showing the overall structure of the present nail chip adhesive sheet 1 and the procedure for cutting the present nail chip adhesive sheet 1 according to the model nails. FIG. FIG. 1B is a schematic plan view showing the entire nail chip adhesive sheet 1 and the cutting line A when cutting, and FIG. 1C is along the cutting line A of FIG. FIG.

  This adhesive sheet for nail chip 1 allows the user to easily operate and enjoy nail art, and the practitioner includes the user himself, but here in order to show the ideal treatment in the nail salon The case where a practitioner performs a procedure will be described. First, the practitioner examines all the nails in both hands of the model in detail before performing the nail tip 3 using the present nail tip adhesive sheet 1, and the model nails are in a special shape such as a deformed nail. Check for any abnormalities, such as whether there is any.

  As shown in FIG. 1 (c), the present nail chip adhesive sheet 1 has an aggregate 4 sandwiched between two substantially transparent pressure-sensitive adhesive sheets 2a and 2b having adhesiveness on both sides and the pressure-sensitive adhesive sheets 2a and 2b. Is formed. In the adhesive sheet 1 for nail chip, the adhesive surfaces (the upper surface of the adhesive sheet 2a and the lower surface of the adhesive sheet 2b in FIG. 1C) are protected by protective sheets 5a and 5b, respectively, until the first use. Yes.

  The nail chip adhesive sheet 1 is cut and used in accordance with the size of the model nail when the practitioner performs the treatment. First, as shown in FIG. 1 (a), the distance 9 from the loose cuticle 6 to the yellow line 7 on the nail of the model is measured using a measure or the like. Next, as shown in FIG. 1 (b), a cutting line A parallel to one side of the nail chip adhesive sheet 1 is drawn on the nail chip adhesive sheet 1 at the distance 9 measured above, and then the nail chip adhesive sheet 1 is used. The adhesive sheet 1 is cut along the cutting line A with a knife or a scissors or the like, and an A cut sheet 12 composed of an A side length 10 and a B side length 11 is created.

  Here, the components of the pressure-sensitive adhesive sheet 2 of the nail chip adhesive sheet 1 of the present invention will be described. The pressure-sensitive adhesive sheet 2 is mainly composed of a thermoplastic elastomer (TPE), a tackifier, and a softening agent, and each of the thermoplastic elastomer (TPE) is 100 parts by weight, the tackifier is 300 to 500 parts by weight, The softener is contained in a proportion of 100 to 150 parts by weight. With this component, it is possible to secure the fixing force to the nail during normal use while allowing repeated pasting and peeling.

  The thermoplastic elastomer is a styrene elastomer (TPS) as a main component, the tackifier is selected from the group consisting of aliphatic hydrocarbon resins, and the softener is preferably a petroleum softener.

  Furthermore, the pressure-sensitive adhesive sheet 2 is preferably added by about 5% to 20% with a water-soluble thickener as an additional component. If a water-soluble thickener is added, the fixing force to the nail can be maintained even when wet.

  Examples of the water-soluble thickener include gelatin, agar, pectin, carrageenan, guar gum, xanthan gum, tamarind gum, propylene glycol, carboxymethyl cellulose, acrylic polymer, and polyacrylamide polymer.

  Next, the structure of the aggregate 4 sandwiched between the adhesive sheets 2 will be described. The aggregate 4 is provided with a number of holes in the thickness direction, and each hole is formed by a frame around the hole, and the holes aggregate to form the entire aggregate 4. A representative example of the aggregate 4 through which the hole in the thickness direction passes is shown in FIG. 2, in which FIG. 2 (a) is a partially enlarged view of an example of a woven structure, and FIG. 2 (b) is a single sheet. A partially enlarged view of a punching metal-like structure example provided with a large number of through holes is shown.

  FIG. 2A shows a so-called mesh structure (mesh fabric) of the woven fabric structure. The weft 4 (x1), 4 (x2) 4 (x3), the warp 4 (y1), 4 (y2), 4 (Y3) is knitted alternately at intervals (mesh pitch) X and Y between adjacent yarns. For example, the weft 4 (x1) is passed from below the warps (y1) and (y3), and the warp (y2) is passed from above. Thereby, the hole (opening) 4c of the aggregate 4 is formed by the warp and the weft, and the frame of the hole is formed by the warp and the weft. The lateral distance X and the longitudinal distance Y of the hole (opening) 4c are mesh pitch-yarn diameter (wire diameter). The ratio (opening area (%)) occupied by the holes 4c in the aggregate 4 is represented by hole area / dotted line area * 100. Further, in the punching metal-like structure example (photograph) in FIG. 2B, a large number of holes 4 e are formed in the material sheet 4 d of the aggregate 4.

  FIG. 3 shows a partially enlarged view (photograph) of a non-woven fabric as an example of porous aggregate 4 having no regular through-holes. From this photograph, the nonwoven fabric has irregularly arranged fibers, and the holes surrounded by the fibers have various shapes, and few penetrate through in the thickness direction.

  Next, a procedure for cutting the A-cut sheet 12 cut in the above description into a size suitable for a model nail will be described with reference to FIGS. FIG. 4A is a schematic diagram showing a situation where the A-cut sheet 12 created above is fitted to the nail of the model, and FIG. 4B shows a cutting line B when the A-cut sheet 12 is cut. It is a schematic diagram.

  As shown in FIG. 4A, the A side length 10 of the A cut sheet 12 created by cutting from the nail chip adhesive sheet 1 is applied to the left side line 13 of the model nail, and the A cut sheet 12 is Fit along the curved surface of the nail. Next, as shown in FIG. 4 (b), the practitioner presses the A-cut sheet 12 fitted to the nail of the model with one hand, and the model is applied to the A-cut sheet 12 with the other hand. A cutting line B is drawn at the same position as the right side line 15 in the nail. After drawing the cutting line B on the A-cut sheet 12, the A-cut sheet 12 is cut along the cutting line B with a knife or a scissors to create a B-cut sheet 17.

  Next, a procedure for further cutting the B cut sheet 17 cut in the above description into a size suitable for a model nail will be described with reference to FIGS. FIG. 5A is a schematic view showing a situation where the B-cut sheet 17 created above is fitted to the model nails, and FIG. 5B is a view of cutting the B-cut sheet 17 on the basis of each part of the model nails. It is the schematic diagram which showed the cutting line C at the time.

  As shown in FIG. 5A, the A side length 10 of the B cut sheet 17 created by cutting from the A cut sheet 12 is applied to the left side line 13 of the model nail, and the B cut sheet 17 is Fit along a curved surface. Next, as shown in FIG. 5 (b), the practitioner presses the B-cut sheet 17 fitted to the model's nails with one hand, and uses the opposite hand to apply the model to the B-cut sheet 17 with the other hand. Cut from the yellow line 7, the loose cuticle 6, the left side line 13, the right side line 15, and the intersection of each line to the center of the nail of the model at a distance of L1 = approximately 1 mm. Draw a line C. After drawing the cutting line C on the B-cut sheet 17, the B-cut sheet 17 is cut along the cutting line C with a knife or a scissors to create a C-cut sheet 21 (see FIG. 6A). At this time, it is desirable to determine the cutting line C flexibly in consideration of the curve of each line described above and the position of the intersection of each line.

  Next, the procedure for attaching the C cut sheet 21 cut in the above description to the nail cross section 22 of the model viewed in cross section will be described with reference to FIGS. FIG. 6A is a schematic diagram showing a state in which only one end of the A protective sheet 5a on the C cut sheet 21 created above is peeled off and a part of the C cut sheet 21 is attached to the nail of the model. FIG. 6B is a schematic diagram showing a state in which the peeling of the partially-separated A protective sheet 5a in the C-cut sheet 21 is gradually promoted and the entire C-cut sheet 21 is attached to the model nails. .

  First, as shown in FIG. 6 (a), the A protective sheet 5a on one side of the C-cut sheet 21 is peeled off by L2 = approximately 5 mm, and the center of the C-cut sheet 21 is arranged so as to overlap the center of the nail of the model. Then, the adhesive part of the C-cut sheet 21 that appears after peeling off the A protective sheet 5a is attached to the nail of the model. Subsequently, as shown in FIG. 6 (b), the practitioner presses a part of the C-cut sheet 21 attached to the nail of the model with a finger in one hand and uses the other hand to partially The A protective sheet 5a that has been peeled off is gripped. While pressing the C-cut sheet, the A-protection sheet 5a is pulled and the peeling of the A-protection sheet 5a is promoted, and the entire C-cut sheet 21 is modeled so that air does not enter between the nails of the model and the C-cut sheet 21. Affix to the nails. Next, the practitioner confirms that the C-cut sheet 21 is firmly attached to the nail of the model, and then peels off the B protective sheet 5 b remaining on the C-cut sheet 21 from the C-cut sheet 21.

  Next, the process proceeds to a procedure for attaching the nail tip 3 to the C-cut sheet 21 attached to the nail of the model. First, the practitioner applies the nail tip 3 to the C-cut sheet 21 affixed to the nail of the model, taking care not to touch the adhesive part that appears when the B protective sheet 5b is peeled off. Then, the air cut into the space between the C-cut sheet 21 and the nail chip 3 is pushed out and pasted while being pressed with a finger. If air enters between the C-cut sheet 21 and the nail chip 3, the C-cut sheet 21 and the nail chip 3 are not sufficiently adhered and may be peeled off during use. is there.

  If the C-cut sheet 21 comes out between the nail of the model and the nail chip 3 when the nail chip 3 is attached, the sheet is cut using a scissors or the like. The practitioner attaches the C-cut sheet 21 and the nail tip 3 to all the nails of the model using the above-described procedure, whereby all the attaching steps are completed.

  The method for attaching the nail chip 3 using the present nail chip adhesive sheet 1 to the nail of a general model has been described above. However, the nail has various shapes and hardness depending on individuals, and depends on the model to be treated. The treatment technique also needs to be optimized. Hereinafter, a treatment method according to various nail shapes will be described.

  FIG. 7A is a schematic diagram showing a model nail having a strong C curve. It is desirable to use a nail tip 3 that is one size larger for a nail having a strong C curve as shown in FIG. The nail tip 3 is adjusted by applying heat using a dryer 23 or the like to reduce the hardness, gradually thickening both sides of the nail tip 3 and deforming it into a shape that matches the C curve of the model nail. . After the shape of the nail tip 3 is adjusted in accordance with the shape of the C curve in the model nail, the nail tip 3 is attached to the model nail using the nail tip adhesive sheet 1 in the same procedure as a normal treatment.

  Next, FIG. 7B is a schematic diagram showing a model nail having a weak C curve and generally called a flat nail. For a flat nail with a weak C curve as shown in FIG. 7B, it is desirable to use a nail tip 3 of a size slightly smaller. The nail tip 3 is adjusted by applying heat using a dryer 23 or the like to reduce the hardness and then gradually spreading both sides of the nail tip 3 so as to be deformed into a shape that matches the C curve of the nail of the model.

  After adjusting the shape of the nail tip 3 according to the shape of the C curve on the model nail, the nail tip 3 is affixed to the model nail using the nail tip adhesive sheet 1 in the same procedure as a normal treatment. However, when a space is generated between the nail of the model and the nail chip 3, the D-cut sheet 24 obtained by cutting the nail chip adhesive sheet 1 according to the space size is laminated and pasted.

  In the schematic diagram of FIG. 8A, a model nail inclined from the loose cuticle 6 toward the toe is shown. When the nail tip 3 is attached to the nail having such a shape in the same procedure as a normal operation, a space is generated between the nail tip and the nail tip 3, and therefore, as shown in FIG. In the same manner, the D-cut sheet 24 obtained by cutting the nail chip adhesive sheet 1 according to the space size only on the toe is overlapped, and the space generated between the toe and the nail chip 3 is filled to perform the treatment.

  Subsequently, in the schematic diagram of FIG. 8B, a model nail having a recess 25 in part is shown. When the nail tip 3 is attached to the nail having such a shape in the same procedure as a normal treatment, a space is generated between the concave portion 25 and the nail tip 3, and the attachment strength of the nail tip 3 is reduced. Therefore, as shown in FIG. 8 (b), first, the D-cut sheet 24 obtained by cutting the nail chip adhesive sheet 1 in accordance with the size of the concave portion 25 is attached to the concave portion 25 and buried. Next, the C-cut sheet 21 and the nail tip 3 are affixed to the nail of the model in the same procedure as a normal treatment.

  Further, even when the nail of the model such as summer is placed in a hot and humid situation, the treatment method for attaching the nail tip 3 using the present nail tip adhesive sheet 1 is different. Under high-temperature and high-humidity conditions, the model hand is likely to perspire, and sweat and water vaporized sweat enter between the nail of the model and the nail chip 3, and the nail and nail chip 3 are bonded by the nail chip adhesive sheet 1. May be reduced.

  When the adhesive sheet 3 for the nail chip is cut according to the nail of the model and the C-cut sheet 21 is created, the C-cut sheet 21 is folded in half as shown in FIG. A part of the C-cut sheet 21 is cut along the cutting line D using a knife or scissors to create the hole 12. After the cutting of the C-cut sheet 21 is completed, as shown in FIG. 9C, the crease is widened, and the model nail is arranged so that the hole 12 cut and provided in the above is arranged at the center of the model nail. Then, the nail tip 3 is affixed to the nail of the model in the same procedure as a normal treatment.

  Next, a procedure for peeling the C-cut sheet 21 and the nail chip 3 attached to the model nails in the above description from the model nails will be described with reference to FIGS. FIG. 10A is a schematic diagram showing a state in which the C-cut sheet 21 and the nail chip 3 attached to the model nail in the above are lifted from the loose cuticle 6 side and floated from the model nail. FIG. 8A is a schematic diagram showing a state in which the C-cut sheet 21 and the nail chip 3 partially lifted from the model nails in FIG. 8A are pulled and peeled to the fingertip side of the model.

  The practitioner checks the state of the C-cut sheet 21 and the nail tip 3 attached to the nail of the model, and then performs a peeling operation. As shown in FIG. 10 (a), first, the practitioner pulls up the nail tip 3 upward from the loose neck 6 side of the model nail, creating a gap between the model nail and the nail tip 3, Hold the gap.

  Subsequently, as shown in FIG. 10B, the practitioner pulls the nail tip 3 attached to the model nail forward from the fingertip of the model and peels the C-cut sheet 21 and the nail tip 3 from the model nail. Let At this time, care is taken not to peel the C-cut sheet 21 and the nail tip 3 upward from the model nails. If the C-cut sheet 21 and the nail chip 3 are peeled away from the model nails many times in the upward direction, the nail plate may be peeled off.

  When a small amount of the adhesive part of the C-cut sheet 21 remains on the nail side of the model, when the C-cut sheet 21 inside the peeled nail chip 3 is lightly pressed again on the model nail and then repeatedly peeled, The adhesive part remaining on the model nails returns to the C-cut sheet 21 side. The practitioner peels off all the C-cut sheets 21 and the nail chips 3 attached to the model nails using the above-described procedure, thereby completing all the peeling steps.

  In addition, when performing the above-described peeling process, when it is difficult to perform the peeling operation of the nail tip 3 such as when the operator's finger slips, work using a finger sack for preventing slipping or a resin glove. May be performed.

  After all the treatment steps using the present nail tip adhesive sheet 1 by the practitioner as described above are completed, the model can attach and peel the nail tip 3 to his nails at any timing. It becomes. With continuous use, dust and dirt such as dust adhere to the adhesive portion of the C-cut sheet 21 created by cutting the nail chip adhesive sheet 1 attached to the inside of the nail chip 3. When the adhesive strength of the adhesive portion of the C-cut sheet 21 is reduced due to the attachment of dust or dirt such as dust, the model can restore the adhesive strength by washing the adhesive portion with water or a neutral detergent. The model can repeatedly use the nail chip 3 using the present nail chip adhesive sheet 1. In addition, the present nail chip adhesive sheet 1 can maintain its fixing force even when it is wet with water in a state of being attached to a nail during normal use.

  Further, in the present nail chip adhesive sheet 1, even if the present nail chip adhesive sheet 1 is cut when the B cut sheet 17 and the C cut sheet 21 as shown in FIGS. Due to the presence, the pressure-sensitive adhesive sheet 2 does not stick out and stick to a cutting tool such as a knife or scissors, and the processing of FIGS. 4 to 6 is facilitated.

  The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to these embodiments, and other embodiments may be used without departing from the spirit and teaching of the claims. It will be readily understood by those skilled in the art that there are variations and modifications.

  The present invention is a connector having a strong adhesive force that allows a decorative nail chip to be repeatedly attached to and peeled from a nail, and dust or the like adheres to the adhesive surface having the adhesive force to Even if it decreases, the adhesive strength can be restored by washing, and it can be used repeatedly, and the adhesive strength when water is attached during use can also be maintained. Furthermore, if this nail chip adhesive sheet is used, it is easy to process at the time of sticking to the nail, and the working time can be greatly reduced, which contributes to activation of market expansion.
