Description

  The present invention is a connector that has a strong adhesive force that enables repeated application and peeling of a decorative nail chip to a nail and can be used repeatedly, and the adhesive force does not decrease even if water adheres. The present invention relates to a chip 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 them, 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. At present, there are many methods for attaching nail chips to nails. “Glue bonding type”, in which nail chips are directly attached to nails using an adhesive dedicated to nail chip application, double-sided tape dedicated to nail chip application The “double-sided tape adhesive type”, in which a nail chip is indirectly attached to the nail using a stick, is famous.

  However, the glue adhesive type has a fixing force, but in order to avoid damaging the nail and nail tip, when peeling the nail tip from the nail, the nail tip is gradually peeled off over time while immersing the finger in warm water. Also, it was troublesome to give care to the surface of the nail. In addition, the double-sided tape adhesive type is easy to apply and peel off, but on the other hand, there is a possibility of peeling during use, which is unsuitable for repeated use.

  In order to solve such a problem, as shown in JP-A-2006-216539, it is a connector having a strong adhesive force that allows a decorative nail chip to be repeatedly applied to and peeled from a nail, and the adhesive There has been proposed an adhesive sheet for a nail chip that can be used repeatedly even if dust or the like adheres to a pressure-sensitive adhesive surface and the adhesive force is reduced to restore the adhesive force by washing.

  However, the adhesive sheet for nail chips can be peeled off and washed with water to restore the adhesive force even if the adhesive strength is reduced. Had the problem of being weak. Specifically, if water adheres to the surface of the adhesive sheet for nail chips during use, a capillary phenomenon occurs in the gap between the nail and the adhesive sheet for nail chips, and water enters and the adhesive strength of the adhesive sheet for nail chips decreases. To do.

  The present invention has been created in view of the above problems, and the present invention is a connector having a strong adhesive force that allows a decorative nail chip to be repeatedly applied to and peeled from a nail, It aims at providing the adhesive sheet for nail chips which can maintain adhesive force even if it adheres.

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,
On the adhesive side,
At least one thermoplastic elastomer (TPE) 100 parts by weight, tackifier 300-500 parts by weight, softener 100-150 parts by weight,
Furthermore, it contains a water-soluble thickener.

  Moreover, it is preferable that the said water-soluble thickener in this nail chip | tip adhesive sheet contains 5-20% concentration of the component of the adhesive surface of the nail chip | tip adhesive sheet.

The water-soluble thickener in the present adhesive sheet for nail chip is a water-soluble polymer for food or industry having a thickening function of a solution to be added,
It was found that gelatin, agar, pectin, carrageenan, guar gum, xanthan gum, tamarind gum, propylene glycol, carboxymethyl cellulose, acrylic polymer, and polyacrylamide polymer can be applied as the main component.

  In the nail chip adhesive sheet of the present invention having the above-described configuration, it is preferable that the thermoplastic elastomer is mainly composed of a styrene elastomer (TPS).

  In the nail chip adhesive sheet of the present invention having the above-described configuration, the hydrocarbon tackifier is preferably selected from the group consisting of aliphatic hydrocarbon resins.

  The softener is preferably a petroleum softener.

  Furthermore, in the adhesive sheet for a nail chip of the present invention having the above-described configuration, it is desirable that the thickness is 0.5 to 0.8 mm.

  According to the present invention, while maintaining the superiority of the above-described nail chip adhesive sheet of Patent Document 2, it is possible to maintain the adhesive strength when water is attached during use.

Specifically, in the nail chip adhesive sheet of the present invention, the nail chip can be easily attached to and peeled from the nail without using a separate chemical or the like, and the adhesive strength can be restored by washing after peeling. The superiority of the adhesive sheet for nail chips provided in Patent Document 2 is maintained.
On the other hand, it has been found that when a water-soluble thickener is used as an additional component of the adhesive sheet for a nail chip, even if water adheres when the nail chip is used, the adhesive force is prevented from decreasing and the fixing force is maintained. This is considered to be because the decrease in the adhesive force due to water adhering to the surface of the nail chip adhesive sheet is compensated by the increase in the adhesive force caused by the water-soluble thickener generated when water is sucked.

  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 FIG. 1 to FIG. 8, 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.

  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 A case where the practitioner performs a treatment 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.

  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 | tip 3 using the adhesive sheet 1 for nail chip | tips from the following is demonstrated. FIGS. 1A and 1B are schematic diagrams showing a procedure for cutting the nail chip adhesive sheet 1 according to the model nails, and FIG. 1A is a schematic diagram showing the model nails. FIG. 1B is a schematic diagram showing a cutting line A when cutting the adhesive sheet 1 for nail chip.

  The adhesive sheet 1 for nail chip of the present invention is a substantially transparent adhesive sheet having adhesiveness on both sides, and the adhesive sheet 1 for nail chip is protected by the protective sheet 5 on both adhesive surfaces until the first use. . As for the said adhesive sheet 1 for nail chips, thickness 0.5mm-0.8mm is excellent in a usability | use_condition, and 0.6mm is more suitable. 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.

  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. 2A is a schematic diagram showing a situation in which the A cut sheet 12 created above is fitted to the nail of the model, and FIG. 2B shows a cutting line B when cutting the A cut sheet 12. It is a schematic diagram.

  As shown in FIG. 2A, 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. 2 (b), the practitioner presses the A-cut sheet 12 fitted to the nail of the model with one hand, and uses the opposite hand to apply the model to the A-cut sheet 12. 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 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. 3A is a schematic view showing a situation where the B-cut sheet 17 created above is fitted to the model nails, and FIG. 3B 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. 3 (a), 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. 3 (b), the practitioner presses the B-cut sheet 17 fitted to the model's nails with one hand, and uses the other 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. 4A). 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, a procedure for attaching the C cut sheet 21 cut in the above description to the nail cross section 22 of the model as viewed in cross section will be described with reference to FIGS. FIG. 4A 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. 4B is a schematic diagram showing a state in which the peeling of the partially removed 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. 4 (a), the A protective sheet 5a on one side of the C-cut sheet 21 is peeled off by L2 = approximately 5 mm, and arranged so that the center of the C-cut sheet 21 overlaps the center of the model nail. 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. 4B, the practitioner presses a part of the C-cut sheet 21 affixed to the nail of the model with a finger in one hand, and partially uses the other hand. 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. 5A is a schematic diagram showing a model nail having a strong C curve. 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 and then gradually pressing both sides of the nail tip 3 so as to be deformed into a shape corresponding to the C curve of the nail of the model. 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. 5B shows 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. 5B, it is desirable to use a nail tip 3 having a slightly smaller size. 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. 6A, 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 treatment, 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. 6B, a model nail having a recess 25 in a part thereof 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 attaching strength of the nail tip 3 is reduced. Therefore, as shown in FIG. 6B, 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.

  In addition, when the model's nails are placed in a hot and humid environment such as in summer, the model's hands are likely to sweat, and sweat and vaporized sweat get into the gap between the model's nails and the nail tip 3. As described above, it is possible to adopt different mounting methods for enhancing the usability.

  When the present nail chip adhesive sheet 3 is cut in accordance with 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. 7C, 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 nail in the above description from the model nail will be described with reference to FIGS. FIG. 8A 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. 8 (a), the practitioner first lifts 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. 8B, 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 in the practitioner described above have been completed, the model can attach and peel the nail tip 3 to his nails at any timing. Become. 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.

  As in the example described above, the nail chip using the adhesive sheet for nail chip of the present invention can be repeatedly used as compared with the conventional method of sticking to a nail using a double-sided tape. Depending on the situation, it is possible to frequently apply and peel the model arbitrarily.

  Next, components of the pressure-sensitive adhesive surface (C-cut sheet 21 or the like) of the nail chip adhesive sheet 1 of the present invention will be described. The adhesive surface of the adhesive sheet 1 for nail chips is similar to the conventional case when the thermoplastic elastomer (TPE), the tackifier and the softener are the main components and the thermoplastic elastomer (TPE) is 100 parts by weight. The tackifier is contained in a proportion of 300 to 500 parts by weight and the softener is contained in a proportion of 100 to 150 parts by weight.

  In the present nail chip adhesive sheet 1, a water-soluble thickener is further added as an additional component. Here, when not adding a water-soluble thickener to the adhesive surface of the adhesive sheet 1 for nail chips, when adding 5%, when adding 20%, it verified about the adhesive force (fixing force) with respect to each nail | claw. .

  As before, when no water-soluble thickener was added, there was no particular problem with the normal adhesive strength, and it was firmly fixed to the nails. On the other hand, it was found that when hand-washed and wetted, the adhesive surface becomes soft and the adhesive strength is greatly reduced, causing wobble or misalignment. Moreover, it turned out that the same thing has arisen when using for a long time. This is presumed to be in a state similar to water wetting due to steam generated from the body when used for a long time.

  When 5% of the total amount of the water-soluble thickener was added, there was no particular problem with the normal adhesive strength, and it was firmly fixed to the nails. In addition, there was no wobbling sensation or misalignment even when wet, and the feeling of use was the same as during normal use. As described above, in the case of the pressure-sensitive adhesive surface of the conventional adhesive sheet 1 for nail chips, a capillary phenomenon occurs in the gap between the nail and the pressure-sensitive adhesive surface when wet, resulting in a decrease in the adhesive force and easy peeling. It is presumed that the adhesive strength increases when water is sucked, and it has a function to separately supplement the adhesiveness due to water wetting.

  When the water-soluble thickener was added for 20% of the total components, there was no particular problem with the normal adhesive strength, and it was firmly fixed to the nails. On the other hand, when wet, it is greatly improved compared to the case where no water-soluble thickener is added, but there is some anxiety about wobble and deviation, and it is understood that this is a boundary that can withstand use when wet. It was. If the water-soluble thickener is contained at a high concentration, it may be eluted on the surface, which reduces the action of the water-soluble thickener that increases the adhesive strength when water is sucked. It is guessed that.

  From the above verification results, when adding a water-soluble thickener to the component of the adhesive surface of the adhesive sheet 1 for nail chips, at the same time, there is an effect of improving the adhesiveness (fixability) when wetted than when not adding, It was found that if the concentration of the water-soluble thickener was increased too much, the tackiness decreased. Specifically, the concentration of the water-soluble thickener is preferably 5 to 20%.

  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.

  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 applied to and peeled from a nail, and the adhesive force is reduced due to adhesion of dust or the like to the adhesive surface having the adhesive force. However, it is possible to restore the adhesive strength by washing and use it repeatedly, and to maintain the adhesive strength when water is attached during use.
