    TECHNICAL FIELD
    [0001] The present disclosure refers to a false nail in a touch, and more particularly, a false nail in a touch capable of preventing the creation of a gap between a false nail and a body of double-sided adhesive tape when it it is placed on the false nail, and able to prevent the peel-off tape from coming off the body of the double-sided adhesive tape during the manufacturing process. BACKGROUND OF THE INVENTION
    [0002] Generally, when it is intended to improve the appearance of a nail by applying nail polish on the nail, the gloss by the nail polish has a gloss intensity of about 40 according to the result of the gloss test by the ASTM D523 standard . However, this corresponds to the case where the nail polish is applied on a smooth surface. To achieve a gloss intensity of about 40 when a nail polish is effectively applied to a person's nail, a base coat, nail polish, and topcoat must be applied to the nails, and the nail polish should be applied. be applied once or twice to give an inherent color to the nail polish. Furthermore, in the event that a solution, such as the base, nail polish, and the topcoat are applied, a solution corresponding to a next step can be applied after a solution corresponding to a previous step has dried. In this process, it takes 20 to 30 minutes to dry the solution using a device to generate wind or the like. Therefore, to apply nail polish with a brightness intensity of 40, at least one and a half hours are spent. In addition, since the solutions are applied in several layers, at least one day is spent until the nail polish or the like dries completely. In addition, during the transition from a semi-dry to a completely dry phase, a scratch can be created by a weak impact that corresponds to 3B, based on the pencil hardness test, and thus the appearance of the nail is greatly impaired .
    [0003] In the related art, in order to solve this problem, a double-sided adhesive tape attached to a false nail has been used for the convenience of users. A general double-sided adhesive tape 5 has a flat shape, as shown in figure 1. Therefore, when double-sided adhesive tape 5 is attached to a false nail 1 having a curved shape, air enters between the face adhesive tape double 5 and the false nail 1 to form a bubble layer B in order to decrease the area where the double sided adhesive tape 5 is glued on the false nail 1. Therefore, the adhesive force that maintains a state where the face adhesive tape double 5 is attached to the false nail 1 is impaired. In addition, during a process where double-sided adhesive tape 5 is attached to the false nail 1, an amount of wrinkles W generated on the double-sided adhesive tape 5 also increases in the curved portion of the false nail 1, or increases the area of the layer of bubbles B. Furthermore, since a restoring force is generated in the double-sided adhesive tape 5 of the peelable tape 4, the wrinkle W is generated more critically. In addition, since the peel-off tape 4 attached to the double-sided adhesive tape 5 also has an inertia to maintain the flat shape, the peel-off tape 4 tends to separate from the double-sided adhesive tape 5 during the process, which it is called the “lifting” phenomenon. In addition, even if the peel-off tape 4 remains in the state attached to the double-sided adhesive tape 5, in the case where the peel-off tape 4 has a greater tendency to remain flat than the double-sided adhesive tape 5, the peel-off tape 4 applies a force to make the double-sided adhesive tape 5 flat, and over time, a gap is created between the false nail 1 and the double-sided adhesive tape 5.
    [0004] Therefore, there is a need to create a false nail in a touch, in which shine and enamel design can be applied on a nail, which can be easily placed on a nail even by an inexperienced person, who can maintain an adhesive force even when applied to a false nail that has a curved shape, which can prevent the phenomenon of “lifting” a detachable tape, and which can minimize adherence of impurities.

    [0029] Figure 6 is a cross-sectional view showing a double-sided adhesive tape according to another embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION
    [0030] From now on, the exemplary modalities will be described in detail with reference to the accompanying drawings. However, these modalities are only to illustrate the present disclosure in more detail, and it is evident to those skilled in the art that the present disclosure is not limited to these modalities.
    [0031] A touch nail in accordance with the present disclosure generally includes a false nail unit 200 that has a nail body 210 replacing the shape of a nail and a design layer 220, and a body of the adhesive tape. double sided 110 and a detachable tape 120 used to place the false nail unit 200 on the nail. A first cut line 114 and a second cut line 124 are formed, respectively, on the body of double-sided adhesive tape 110 and on detachable tape 120. The first cut line 114 and the second cut line 124 are, respectively, formed through the body of the double-sided adhesive tape 110 and the detachable tape 120. Therefore, when the body of the double-sided adhesive tape 110 and the detachable tape 120 having a flat shape are placed on the nail body 210 they have a curved shape, the air located between the nail body 210 and the double-sided adhesive tape body 110 is expelled through the first cut line 114 and the second cut line 124. Therefore, the area where the double-sided adhesive tape for a nail false contacts the false nail, and a cohesive force improves compared to the existing one. In addition, since the first cut line 114 and the second cut line 124 are formed in a linear fashion, the stiffness of the double-sided adhesive tape can be maintained. In other words, during a process where the peel-off tape 120 is removed from the body of the double-sided adhesive tape 110, it is possible to prevent the body of the double-sided adhesive tape 110 from tearing. In addition, since the area of the peelable tape 120 is larger than the body area of the double-sided adhesive tape 110, it is possible to prevent impurities from getting caught in the double-sided adhesive tape.
    [0032] Figures 2a and 2b are seen in perspective and in cross-section showing a false nail in a touch according to a modality of the present description, and figures 3a to 3c are frontal views showing various modalities of the false nail in a touch in accordance with this disclosure.
    [0033] The false nail in a touch according to the present disclosure, as shown in figures 2a and 2b, the false nail in a touch includes a nail body 210, design layers 220 formed in the upper portion of the nail body 210 , a double-sided adhesive tape body 110 formed on the lower portion of the nail body 210, and a detachable tape 120 located on the lower portion of the double-sided adhesive tape body 110.
    [0034] The nail body 210 includes one end 211 coupled to be located on one side of the free end of the nail, the other end 213 coupled to be located on one side of the nail cuticle, and an adhesive surface 219 formed at one location on the nail.
    The body of the double-sided adhesive tape 110 includes a plurality of unconnected portions 114a formed by cutting a plurality of first cut lines 114, and a connecting portion 112a formed between the first lines of cuts 114 so that the plurality of unconnected portions 114a are not separated from each other.
    [0036] The body of the double-sided adhesive tape 110 is formed, except for a non-cohesive portion, on the lower edge of the nail body 210; the non-cohesive portion includes a non-cohesive portion at one end 211 of the nail body 210, a non-cohesive portion at the other end 213 of the nail body 210, and a non-cohesive portion on both sides 215 of the nail body nail 210; the non-cohesive portion at one end 211 of the nail body 210 is a portion corresponding to 1/3 to 1/50 of the nail length of an end 211 of the nail body 210; the non-cohesive portion at the other end 213 of the nail body 210 is a portion corresponding to 1/7 to 1/100 of the nail length of the other end 213 of the nail body 210; and the non-cohesive portion on both sides 215 of the nail body 210 is a portion corresponding to 1/5 to 1/100 of the nail length of both side ends 215 of the nail body 210.
    [0037] Detachable tape 120 has a larger area than the double-sided adhesive tape body 110, and the double-sided adhesive tape body is placed on the top portion of the detachable tape 120 so that the adhesive tape body double-sided 110 is not bypassed with peel-off tape 120 a plurality of second cut lines 124 are provided on the peel-off strip 120 to pass through the upper and lower surfaces of the peel-off strip 120, and the peel-off strip 120 has a flap 122 that connects and extends beyond the outer circumference at one end 211 of the nail body 210.
    [0038] The nail body 210 corresponds to a nail shape and provides a regular shape to the user's nail so that the overall shape of the user's nail can improve. A design layer 220 with a painted design on the nail body 210 is formed on the upper surface 217 of the nail body 210 which provides such an improved shape for the nail. In other words, if the nail body 210 provides an improved shape to the nails, the drawing layer 220 provides a painting effect using nail polish or the like for the nails. A coating layer 230 can also be provided for the upper portion of the design layer 220, in order to protect the surface and increase the gloss which improves the appearance of the design.
    [0039] When the false nail in a touch according to the present disclosure is produced, if all the following conditions are not simultaneously satisfactory, the defects can be generated due to the separation of the detachable tape during an automated manufacturing process. In addition, during the process of placing the nail unit, a problem may occur in separating the peelable tape, and it has also been found that impurities are attached to the nail unit after the nail unit is attached.
    [0040] In other words, i) between the non-cohesive portions on the lower edge of the nail body 210, the non-cohesive portion located at the end 211 of the nail body 210 should be separated by 1/3 to 1/50 of the nail body length 210 from one end 211 of nail body 210, ii) the non-cohesive portion at the other end 213 of nail body 210 should be separated by 1/7 to 1/100 of the length of the nail body nail 210 of the other end 213 of the nail body 210, and iii) the non-cohesive portions located on both sides 215 of the nail body 210 must be separated, respectively, by 1/5 to 1/100 of the width of the nail body. nail 210 on both sides 215 of the nail body 210. In addition, iv) the peel-off tape 120 must have an area larger than the body of the double-sided adhesive tape 110, and the body of the double-sided adhesive tape must be placed on the upper portion of the peel-off tape 120 so that the body of the double-sided adhesive tape 110 is not deflected from the peel-off tape 120, v) the second cut lines 124 formed in the same locations while the plurality of first cut lines 114 in a vertical direction must be provided in the peelable strip 120, and vi) the peelable strip 120 must have a flap 122 that connects and extends beyond the outer circumference at one end 211 of the nail body 210.
    [0041] Here, the cohesive force of the coating layer 230 and the paint applied to the drawing layer 220 is preferably 30% or less, as a result of the ASTM D3359 test using a cross section. In other words, the area of the paint and the coating layer detached 230 after the test is preferably 30% or less. In the case of an external force applied to a nail during daily life, a person may not be aware of the impact it can cause before the nail breaks or scratches. In other words, since a person does not feel pain because of an external force caused in daily life, even if the person comes to perceive the action of an external force, the person does not reach a stage of perception where the user performs actions such as stopping current behavior or checking a portion where external force is applied. In other words, in the case where the cohesive force is greater than 30%, although an external force is continuously applied to the nail during daily life, the external force cannot be recognized. Therefore, the external force being continuously and repeatedly applied to the false nail in one touch is so intense that it peels the paint and the coating layer 230. Therefore, the cohesive force of the coating layer 230 and the paint applied to the drawing layer 220 according to the present disclosure they are preferably adjusted to be 30% or less so that the coating layer 230 and the paint applied to the drawing layer 220 can be protected from external force.
    [0042] In addition, when an external force of less than 1B is applied to the nail, based on the pencil hardness test, the impact is generally not recognized. In other words, only when a scratch is created on the nail due to an external force of 2.5 or more in Mohs hardness, does a person recognize the external force and interrupt his behavior in order to stop the creation of a scratch. As a result of the pencil hardness test by ASTM D3363, the hardness of the coating layer 230 according to the present disclosure is preferably 1B or greater. In other words, when an external force is less than 1B, based on the pencil hardness, it is applied to the coating layer 230 on a daily basis, a scratch is not created. At this point, in the case where the hardness of the coating layer 230 is less than 1B, if an external force of less than 1B, based on the hardness in the pencil, is applied to the coating layer 230 on a daily basis, a scratch is created on the coating layer 230 spoiling the appearance of the false nail in one touch. Therefore, the hardness of the coating layer 230 is preferably 1B or greater so that the good appearance of the false nail in one touch can be maintained during everyday life.
    [0043] In addition, according to a gloss test result by the ASTM D532 standard, the gloss of the coating layer 230 is preferably 50 or higher.
    [0044] Generally, the nail surface is meticulously curved. Therefore, in the case where the shine is applied to it, the nail surface appears to be smooth. For this purpose, the coating layer 230 according to the embodiment of the present disclosure preferably has a brightness intensity of 50 or higher. In the case where the gloss is less than 50, although the surface formed is actually smooth, the surface of the nail body 210 is observed to be curved, as if there were fine scratches. Therefore, in order to improve the appearance of the nail, in the case where a false nail is placed, the gloss is preferably 50 or higher.
    [0045] The second cut line 124 is formed on the peelable tape 120 to pass through the peelable tape 120. Since the first cut line 114 and the second cut line 124 cut a partial region of the face tape body double 110 and the detachable tape 120 is formed with a flat shape by the inertia of the body of the double-sided adhesive tape 110 and the detachable tape 120 applied to the false nail and the nail, these tend to recover the flat shape. Therefore, the state in which the body of the double-sided adhesive tape 110 applied to the curved surface can continuously maintain its state of adhesion to the nail body 210 through the first cut line 114 and the second cut line 124.
    [0046] Since the double-sided adhesive tape 110 and the peel-off tape 120 are applied to the nail body 210, their outer circumferential shapes also correspond to the body shapes 210 and the nail. In other words, the name of the outer circumference of the double-sided adhesive tape body 110 changes according to its location when it is applied to the nail. Here, the outer circumference designates only one edge in the shape of the nail, and the regions divided by the first cut line 114 and second cut line 124 do not correspond to the outer circumference. In other words, considering that the side surface 115 of the double-sided adhesive tape body 110 is divided by the first cut line 114, the outer circumference of the side surface 115 does not have a "T" shape, but it does have a shape in "-". One end 111 of the double-sided adhesive body 110 is located on the side of the free edge of the nail, and the other end 113 is located on the side of the cuticle. In addition, side surface 115 is arranged to be located on the nail surface (nail wall). The nail body 210 is attached to the upper surface 117 of the double-sided adhesive tape body 110, the nail is placed on the lower surface 119. At this point, before the double-sided adhesive tape body 110 is placed on the nail, the tape peelable 120 is detachably placed on the bottom surface 119 of the double-sided adhesive body 110. Therefore, the adhesive surface 219 of the nail body 210, as shown in figure 2a, the double-sided adhesive body 110 and the Detachable tape 120 formed with a flat plate shape are joined.
    [0047] The first cut line 114 and the second cut line 124 can be installed in different locations depending on the body properties of double-sided adhesive tape 110 and peel-off tape 120. However, to prevent a gap from being created between the body of the double-sided adhesive tape 110 and the nail body 210, the second cut line 124 can be formed in the same locations, as the plurality of first cut lines 114 in the vertical direction. Here, the first cut line 114 formed on the body of the double-sided adhesive tape 110 and the second cut line 124 formed on the peelable tape 120, not only disperse the inertia to restore its flat shape, but also play a role in unloading gently air between the double sided adhesive tape 110 and the nail body 210 during the process in which the double sided adhesive tape body 110 is attached to the nail body 210. The nail body 210 has a curved shape, and the body of the double-sided adhesive tape 110 has a flat shape. Therefore, to place the double-sided adhesive tape 110 which has a flat shape on the nail body 210, the side surface 115 of the double-faced adhesive body 110, first makes contact with the side 215 of the nail body 210. In doing so, when the body of the double-sided adhesive tape 110 which has a flat shape is placed on the body of the nail 210, a layer of bubbles is inevitably created between the body of the double-sided adhesive tape 110 and the body of the nail 210 In the present description, in order to solve this problem, the air in the bubble layer can be expelled through the first cut 114 and the second cut line 124. In particular, coinciding the locations, if the first cut line 114 and the second cut line 124 are formed, it is possible to limit the creation of a space between the false nail in one touch and the false nail. In other words, as shown in figure 2b, in the case where the locations, where the first cut line 114 and the second cut line 124 are formed, are the same, the air located between the body of the double-sided adhesive tape 110 and the nail body 120 can be easily unloaded while passing through the first cut line 114 and the second cut line 124, in sequence.
    [0048] Furthermore, since the peel-off tape 120 is provided to have an area larger than the double-sided adhesive tape body 110 it is possible to decrease the exposure of the double-sided adhesive body 110 to a minimum. For example, in the case where the peelable tape 120 is made to have the same area as the body of the double-sided adhesive tape 110, the side surface 115 of the body of the double-sided adhesive tape 110 is entirely exposed so that the impurities are attached to the side surface 115 of the double-sided adhesive tape body 110. In addition, if the double-sided adhesive tape body 110 is compressed when the temperature and flexibility increase, its thickness can be reduced and its area can be reduced. be increased simultaneously. Even if the temperature does not increase, when a pressure is applied during the process, the area can be increased almost instantly. As described above, the area of the peelable tape 120 is larger than the area of the double-sided adhesive tape 110 in order to prevent the body of the double-sided adhesive tape 110 from being exposed early. In addition, if the peel-off tape 120 is formed to have a large area, the peel-off tape 120 can be clearly divided from the body of the double-sided adhesive tape 110. Therefore, even if the body of the double-sided adhesive tape 110 does not whether caught by one hand, the peel-off tape 120 can be removed. Therefore, the cohesive strength of the double-sided adhesive tape body 110 can be maintained, and since the double-sided adhesive tape body 110 does not need to be compressed, the thickness of the cohesive surface can be maintained consistently. As shown in figures 3a to 3c, since the flaps 122, 122 ', 122 "are formed on the peelable strips 120, 120', 120" to extend with the same flat shape over the outer circumferences of the peelable strips 120, 120 ', 120 "having a nail shape, the detachable tapes 120, 120', 120" can more easily be removed from the body of the double-sided adhesive tape 110. At this time, the flaps 122, 122 ', 122 "extend beyond of the outer circumference of the false nail unit 200 so that the location of the flap can be seen with the naked eye, even though the false nail unit 200 is located in the upper portion and thus the location of the double-sided adhesive tape body 110 is not checked with the naked eye.
    [0049] The number of cuts in the first cut lines 114, 114 ', 114 "and in the second cut lines 124, 124', 124", respectively formed on the bodies of double-sided adhesive tapes 110, 110 ', 110 " and on detachable tapes 120, 120 ', 120 ", can be changed according to the curvature and size of the nail body 210. In other words, if a curvature is so great that a great restorative force is applied to the detachable tape 120 , as shown in figure 3a, a first cut line 114 and a second cut line 124 can additionally be formed separately within the body of the double-sided adhesive tape 110 and the outer circumference of the peelable tape 120. In addition, as shown in figures 3b and 3c, the connection portions 112a 'and 112a "can be formed in only one point on the bodies of double-sided adhesive tapes 110' and 110" and the detachable tapes 120 'and 120 ", so that the first cut lines 114 'and 114 "and second cut lines 124' and 124" are, r expectantly formed outwardly in a radial direction based on the connecting portions 112a 'and 112a ". Here, the second cut lines 124, 124 ', 124 ”formed at the same locations as the first cut lines 114, 114', 114" can be formed to extend to the outer circumferences of the detachable strips 120, 120 ', 120 ” In other words, by extending the second cut lines 124, 124 ', 124 "to the outer circumferences of the detachable tapes 120, 120', 120", the detachable tapes 120, 120 ', 120 "may not be restored in the flat direction. In addition, the second cut line can be formed at a location of the peelable strip different from the location where the first cut line is formed.
    [0050] Here, the second cut lines 124, 124 ', 124 "are preferably not formed on the outer circumferences, in places where the flaps 122, 122', 122" are formed. In other words, when the flaps 122, 122 ', 122 "are gripped and the peelable strips 120, 120', 120" are separated, the peelable strips 120, 120 ', 120 "can be easily removed from the bodies of the adhesive tapes. double sided 110, 110 ', 110 "to increase the stiffness of the places where the flaps 122, 122', 122" are formed. For example, in the case where the flap 122 is formed on the other end 123 of the detachable tape 120, the second cut line 124 is not formed to extend to another end 123 of the peelable strip 120, while in the case where the flaps 122 'and 122 "are formed on the sides 125' and 125" of the peelable strips 120 'and 120 " , the second cut lines 124 'and 124 "are not formed to extend to the sides 125' and 125" of the detachable strips 120 'and 120 ". In the case where the second cut lines 124, 124', 124" are provided on the outer circumferences in the places where the flaps 122, 122 ', 122 "are formed, the force applied in the direction of the movement of the flaps 122, 122 ', 122 "is focused on the second cut lines 124, 124', 124" to prevent the connecting portions 112a, 112a ', 112a "formed on the detachable strips 120, 120', 120" from breaking, thereby preventing that the detachable tapes 120, 120 ', 120 "will be divided into several parts. Therefore, the second cut lines 124, 124 ', 124 "are preferably separated from the outer circumferences at the places where the flaps 122, 122', 122" are formed.
    [0051] In addition, although the body area of the double-sided adhesive tape 110 changes instantly, as described above, during the process, the properties of the detachable tape 120 can be adjusted so that the adherence of impurities to the tape body Double-sided adhesive 110 can be prevented to maintain cohesive strength.
    [0052] Figures 4a and 4b are seen in cross-section showing a false nail in a touch according to a modality of the present disclosure.
    [0053] First, if the body of the double-sided tape 110 becomes flat by an external force, such as pressure, the peel-off tape 120 can also be stretched according to the change in the shape of the body of the face tape double 110. Therefore, it is possible to prevent the cohesive component of the double-sided tape body 110 from exposing the peel-off tape 120 in the radial direction, and it is possible to prevent the peel-off tape 120 and the double-sided tape body 110 peel off. In other words, since the peelable tape 120 and the double-sided adhesive tape body 110 can handle the external force in the same way, the peeling caused by different actions against the external forces can be avoided. First, as shown in figure 4a, if the peel-off tape 120 is applied to the curved surface, the length of the top surface 127 of the peel-off tape 120 increases so that the peel-off tape 120 can be easily applied to the curved surface along the body double-sided adhesive tape 110. Therefore, it is possible to prevent the body of double-sided adhesive tape 110 and peel-off tape 120 from peeling off.
    [0054] In addition, as shown in figure 4b, a part of the peelable strip 120 located where the second cut line 124 is formed can be inserted between the first cut lines 114 to improve the coupling force between the peelable tape 120 and the double-sided tape body 110. When the first cut line 114 and the second cut line 124 are formed at the same location, the cut lines are formed simultaneously using a single cutter. In this process, a part of the peel-off tape 120 is instantly inserted between the first cut lines 114 and a part of the peel-off tape 120 is attached to the body of the double-sided adhesive tape 110. However, since the peel-off tape 120 has the detachable property of the double-sided adhesive tape body 110, the peel-off tape 120 is not perfectly adhered to the double-sided adhesive body 110 during this process. Therefore, by controlling the physical properties of the peelable tape 120, it has been preferred to manufacture peelable tape 120 having a property of detaching from the body of the double-sided adhesive tape 110 without rising from the body of the double-sided adhesive tape 110, due to to a restorative force.
    [0055] For this purpose, the detachable tape 120 can be made of any one between PE, EVA, PP, POE, and PET, or its copolymers or mixtures.
    [0056] In addition, the peel-off tape 120 preferably has a tensile strength of 5 kg / cm2 or greater. The tensile strength is a maximum stress until a test piece breaks due to a tensile load and represents a value obtained by dividing the maximum load until the rupture of an original cross section. Here, the peel-off tape 120 is formed to require a force of 5 kg / cm2 or greater for the entire tear, thereby preventing peel-off strip 120 from tearing during a process where peel-off strip 120 is peeled off. The double-sided adhesive tape body 110 applied to the false nail in a touch in accordance with the present disclosure uses a force of less than 5 kg / cm2 to separate the peelable tape 120. Therefore, in the case where the tape's tensile strength peel-off 120 is less than 5 kg / cm2, during the process where peel-off tape 120 is separated, peel-off tape 120 is torn so that the residues of peel-off tape 120 remain in the body of double-sided adhesive tape 110. In this case, during the process where the residues of the peelable tape 120 are removed by the hands, if the oil from the hands makes contact with the bottom surface 119 of the double-sided adhesive body 110, the cohesive force of the double-sided adhesive body 110 is impaired, causing the false nail in a touch to lose its original function. In addition, although the residues of the peelable tape 120 are treated using other tools, if the body of the double-sided tape 110 is pressed during the residual removal process, the surface of the body of the double-sided tape 110 becomes unevenly deformed. so that the cohesive force of the double-sided adhesive body 110 cannot be applied uniformly to the nail. Therefore, the performance of the false nail in one touch cannot be implemented. In other words, the peel-off tape 120 according to the present disclosure has a tensile strength of 5 kg / cm2 or greater, in order to prevent residues of peel-off tape 120 from remaining in the body of double-sided adhesive tape 110 and to maintain the cohesive property of the double-sided adhesive tape body 110 evenly.
    [0057] In addition, when the peelable strip 120 is made of the above materials, the peelable strip 120 thickness is preferably from 30 μm to 300 μm. If the thickness of the peel-off tape 120 is less than 30 μm, the stiffness of the peel-off tape 120 is deteriorated, and thus the peel-off tape 120 is torn when the peel-off tape 120 is detached from the body of the double-sided adhesive tape 110. Therefore, a portion of the peel-off tape 120 inevitably remains in the body of the double-sided adhesive tape 110. In particular, in the case where the double-sided adhesive tape 110 has the cohesive force to attach to the nail, the peel-off tape 120 is inevitably broken Since the tension is focused on the point of the second cut line 124 formed in the same position as the first cut line 114, although the strength of the peelable tape 120 is maximized. In other words, regardless of the strength of the peelable tape 120, the thickness of the peelable tape 120 should be 30 μm or more. In addition, in the case where the thickness of the peelable strip 120 exceeds 300 μm, since the inertia, through which the peelable strip 120 restores an increase in the flat shape, a lifting phenomenon occurs in the peelable strip 120. In addition, in the event that the release force decreases to contain the lifting phenomenon of the peel-off tape 120, the clamping force between the peel-off tape 120 and the body of the double-sided adhesive tape 110 increases so that the body of the face-adhesive tape double 110 receives a restoring force from a flat shape by the detachable tape 120. Therefore, a gap is inevitably created between the body of the double-sided adhesive tape 110 and the false nail. In addition, if the release force decreases, the peel-off tape 120 cannot be easily removed from the body of the double-sided adhesive tape 110, and thus the original purpose of the present disclosure is lost. Therefore, regardless of the release force, the thickness of the peel-off tape 120 should be from 30 μm to 300 μm, to easily separate the peel-off tape 120 from the body of double-sided adhesive tape 110 and avoid the phenomenon of "lifting".
    [0058] Figures 5a and 5b are seen in cross-section showing a double-sided adhesive tape applied to the nail according to a modality of the present disclosure and a comparative example.
    [0059] In order to improve the cohesive force for the coupling of the upper surface 117 and the lower surface 119 of the double-sided adhesive tape body 110, respectively for the nail body 210 and the nail, many other methods can be used to improve the cohesive strength of the double-sided adhesive tape body 110. First, in order to improve the cohesive strength of the double-sided adhesive tape body 110, a gap must not be created between the body of the adhesive tape double-sided 110 and the nail body 210. In addition, the cohesive force between the N-nail and the double-sided adhesive tape body 110 can be improved by forming the double-sided adhesive tape 110 over a predetermined thickness.
    [0060] In the present description, in order to prevent the entry of impurities between the body of the false nail and the nail, and to maintain a state where the false nail in one touch is attached to the nail, the double-sided adhesive tape 110 is preferably formed to have a thickness of 150 μm to 800 μm. In other words, in the case where the thickness of the double-sided adhesive tape body 110 is 150 μm to 800 μm, as shown in figure 5a, the cohesive component of the double-sided adhesive tape body 110 is uniformly applied to the nail surface to expose a cohesive force on the nail surface. In addition, since the cohesive component is evenly distributed between the rough surfaces of the nail, the false nail can be placed on the nail. Therefore, the false nail can be attached to the nail for a long time.
    [0061] However, in the case where the thickness of the double-sided adhesive tape body 110 is less than 150 μm, as shown in figure 5b, the double-sided adhesive tape body 110 is adhered only to the protruding portions of the nail, and so the area where the double-sided adhesive tape 110 is cohesive decreases considerably. In addition, if simple adhesion by nail oil is used without the involvement of the nail, the body of the double-sided adhesive tape 110 cannot be attached to the nail. Therefore, the thickness of the double-sided adhesive tape body 110 is preferably 150 µm or greater.
    [0062] Furthermore, in the case where the thickness of the double-sided adhesive tape body 110 exceeds 800 μm, the gap between the nail and the false nails increases so that hair or impurities are trapped in it so that the force of cohesion of the body of the double-sided adhesive tape 110 further decreases. In addition, in case the hair is touched by the hand, the hair is attached to the body of the double-sided adhesive tape 110. When separating the hair, a pain is caused, and the sensation of wear increases. Therefore, the thickness of the body of the double-sided adhesive tape 110 is preferably 150 μm to 800 μm.
    [0063] Furthermore, since the double-sided adhesive tape 110 plays a role of adhesion of the nail to the body of the nail 210 of the false nail in one touch, when the location of the body of the nail 210 changes relatively in relation to the nail, the body of the double-sided adhesive tape 110 must not peel. In other words, when an external force is applied to remove the false nail in a touch of the nail, the double-sided adhesive tape 110 should not remain partially on the nail. For this proposal, as a result of the peel resistance test at 180 ° using SUS according to the ASTM D903 standard, the peeling force of the double-sided adhesive body 110 is preferably 300 gf / 10mm or greater. In addition, as a result of the 90 ° peel strength test using ABS, the peel strength of the double-sided adhesive body 110 is preferably 100 gf / 10mm or greater. In other words, in the case where the double-sided adhesive tape body 110 is manufactured to have a 300 gf / 10mm peeling strength in the 180 ° peel strength test using SUS, if a shear force is applied in the plane direction of the double-sided tape body 110 during use in everyday life, the nail body 210 is detached in a state where the double-sided tape body 110 is partially adhered to the nail. In addition, during the process where the one-touch nail is detached for exchange, the body of the double-sided adhesive tape 110 can peel off leaving residues. Likewise, in the case where the double-sided adhesive tape body 110 is manufactured to have a peeling strength of less than 100 gf / 10mm in the peel strength test at 90 ° using ABS, if an external force is applied in one direction Perpendicular to the plane of the double-sided adhesive tape body 110 during everyday life, the nail-body 210 is detached in a state where the double-sided adhesive tape body 110 is partially adhered to the nail. In other words, if an external force is applied to the nail body 210 towards the upper surface 217, the nail body 210 is separated in a state where the double-sided adhesive tape 110 is partially adhered to the nail. In addition, during the process where the one-touch nail is detached for replacement, the body of the double-sided adhesive tape 110 also peels and leaves residues on the nail. Therefore, it has been preferred to manufacture the double-sided adhesive tape body 110 which has a peel strength of 300 gf / 10mm or greater in the peel strength test at 180 ° using SUS under the ASTM D903 standard, and a peel strength of 100 gf / 10mm or greater with 90 ° peel strength test using ABS.
    [0064] Figure 6 is a cross-sectional view showing a double-sided adhesive tape according to another embodiment of the present disclosure.
    [0065] The body of the double-sided adhesive tape 110 applied to the false nail in a touch according to the present disclosure can be provided in a single layer or a laminated structure, where a plurality of layers is laminated. In particular, in the case where the body of the double-sided adhesive tape 110 is formed in several layers, in order to prevent the other end 213 of the nail body 210 from compressing the cuticle, although an external force is applied to one end 211 of the nail body 210, the double-sided adhesive tape body 110 preferably includes a substrate layer 110a, and the cohesive layers 110b and 110c, respectively, coupled to the upper and lower portions of the substrate layer 110a. Here, the substrate layer 110a can be made of any one of PET, PE, PP, EVA, POE, and non-woven fabric. The substrate layer 110 allows the cohesive layers formed in the upper and lower portions of the substrate layer 110a not to be pushed due to the characteristics of the material when forces parallel to the plane are received. Therefore, although common behaviors are performed after the fingernail in a touch is used, the cuticle is not compressed, causing no pain. In addition, the first cohesive layer 110b and the second cohesive layer 110c respectively located in the upper and lower portions of the substrate layer 110 may have the same adhesive strength and the same material, but may have different adhesive characteristics. In a case where the adhesive characteristics are different, the first cohesive layer 110b and the second cohesive layer 110C can be perfectly made of a material capable of increasing the adhesive strength with the nail and the material capable of increasing the adhesive force with the body of the nail 210 so that the false nail in one touch can be attached to the nail for a long time.
    [0066] Simple changes or modifications to the present disclosure can be made easily by those skilled in the art, and these changes and modifications can be recognized as being included within the scope of this description.
