Description

Technical Field

[0001] The invention relates to the field of nail art nail tips, and in particular to a comfortable nail art nail tip and a nail tip assembly having the nail art nail tip. Background Art

[0002] Existing nail tips are usually designed to imitate the surface of human nails (standard nail shape), among which: the back of the nail tips is designed to imitate the surface of human nails. This is because after the nail tips are pasted to the surface of human nails (the back of the nail tips are pasted to the surface of human nails), the back of the nail tips is closer to the surface of human nails, the user has less foreign body sensation, and the overall feeling is more comfortable; the front of the nail tips is also designed to imitate the surface of human nails. The advantage is that after the nail tips are pasted to the surface of human nails, the imitating front of the nail tips replaces the surface of human nails, and the visual effect is more natural and realistic.

[0003] To attach the nail art tips to the surface of a person's nail, you need to first apply gel on the back of the nail art tips, attach the back of the nail art tips to the surface of the user's nail to be shaped, and then use UV light or the like to irradiate the gel to solidify it, and the attachment is complete. Since the back of the nail art tips needs to be coated with gel between the back of the nail art tips and the surface of the human nail, an additional space needs to be reserved for the gel, so it cannot completely conform to the surface of the user's nail; and since the shape data of each person's nails is slightly different from the standard nail shape, even if the back of the nail art tips is designed to conform to the surface of the nail of the standard nail shape, it may not be completely conformed to the surface of the user's nail. Therefore, after the nail art tips are attached to the surface of the human nail, the user still feels a certain degree of discomfort. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a comfortable nail art nail plate and a nail plate assembly having the nail art nail plate, which can make the user feel more comfortable after being pasted to the surface of the human nail even if the back side of the nail plate cannot completely conform to the shape of the human nail surface.

[0005] To solve the above problems, the present invention provides a comfortable manicure nail plate, comprising a nail plate body that can be placed flat on a horizontal plane, the back of the nail plate body is arched upward, and the rear edge of the back of the nail plate body is suspended above the horizontal plane, and the highest point of the rear edge is 1.5mm to 4.4mm.

[0006] Furthermore, at least part of the edge surface of the nail piece body faces downward as a bottom surface, and among the bottom surfaces, the highest point of the rear bottom surface is suspended above the horizontal plane on which it is placed, and its height is 1.7 mm to 4.6 mm.

[0007] Furthermore, the height of the highest point of the rear bottom surface is 0.1 mm to 0.2 mm higher than the height of the highest point of the rear edge.

[0008] Furthermore, the front edge of the back side of the nail piece body is suspended above the horizontal plane on which it is placed, and the highest point of the front edge is 0.2 mm to 5.4 mm in height.

[0009] Furthermore, the highest point of the front surface of the nail piece body is suspended above the horizontal plane on which it is placed, and its height is 0.5mm to 6.2mm.

[0010] Furthermore, the front edge of the back side of the nail piece body is suspended above the horizontal plane, the highest point of the front edge is 0.2mm to 5.4mm high, and the highest point of the front edge is 0.3mm to 0.8mm lower than the highest point of the front surface of the nail piece body.

[0011] Furthermore, the total length of the nail plate body in the front-to-back direction is 12.5 mm to 34 mm.

[0012] Furthermore, the outer width of the nail plate body is 6.5 mm to 15 mm.

[0013] A nail plate assembly is also provided, comprising a plurality of nail plates of different sizes, wherein at least one nail plate is the above-mentioned nail art nail plate.

[0014] Furthermore, there are five nail plates, which are respectively used to be adhered to the surfaces of the nails of five fingers on the same palm of a person.

[0015] Beneficial effect: The nail art nail piece of the present invention has a maximum height of 1.5 mm to 4.4 mm on the back edge of the back side of the nail piece body. Even if the back side of the nail piece body cannot completely conform to the surface of a human nail, it has been verified through experiments that the nail art nail piece can still make the user feel more comfortable after being pasted on the surface of a human nail.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with specific implementation methods.

[0026] The nail plate assembly includes five nail plates, the sizes of which are different, and are used to be attached to the surfaces of the nails of five fingers on the same palm of a person. Take one of the plates as an example, see Figure 1 The nail plate body 1 includes a nail plate body 1, which is bilaterally symmetrical, with a back side 11 arched upward; the left side, right side, and rear side edge surfaces 12 of the nail plate body 1 face downward as the bottom surface, and the nail plate body 1 can be as Figure 2 As shown, the bottom surface 121 (see Figure 3 The back side 11 of the nail plate body 1 can be attached to the surface of a human nail after being coated with gel, but since the back side 11 of the nail plate body 1 cannot completely conform to the surface of the user's nail, it is easy to cause a certain degree of discomfort to the user after being attached to the surface of the human nail.

[0027] The inventors have found that when the back side 11 of the nail plate body 1 cannot completely conform to the surface of the human nail, there are multiple factors that affect the user's comfort after the nail plate is attached to the surface of the human nail. The shape of the back side 11 of the nail plate and the center of gravity of the nail plate itself have a greater impact on the comfort, and these two factors are affected by multiple subordinate factors such as the total length of the nail plate body 1, the edge height, and the edge surface height. Among them, the inner height A of the back edge of the nail plate body 1 (see Figure 2, the rear edge 111 of the back side 11 of the nail plate body 1 is suspended above the horizontal plane on which it is placed, and the rear edge inner height A (i.e., the height of the highest point 1111 of the rear edge 111 of the back side 11 of the nail plate body 1) has a greater impact. In order to test the difference in comfort brought about by different values ​​of the rear edge inner height A of the nail plate body 1, the following Table 1 is obtained in the experiment:

[0028] Serial number Specific value of the inner height A of the rear edge of the nail plate body 1 Comfort rating Experimental Group 1 4.4mm 93 Experimental Group 2 4.4mm 92 Experimental Group 3 4.4mm 92 Experimental Group 4 4.4mm 92 Experimental Group 5 4.4mm 91 Experimental Group 6 1.5mm 93 Experimental Group 7 1.5mm 90 Experimental Group 8 1.5mm 91 Experimental Group 9 1.5mm 93 Experimental Group 10 1.5mm 90 Control group 11 5.68mm 75 Control group 12 5.68mm 77 Control group 13 1.34mm 79 Control group 14 1.34mm 77

[0029] Note: In the 14 groups of data given in Table 1 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on the nail tips with corresponding values. Except for the different values ​​of the inner height A of the rear edge of the nail tip body 1, the other parameters of the tried-on nail tips are the same: the outer height B of the rear edge of the nail tip body 1 (see below for specific meaning) is 4.6mm; the inner height C of the front edge of the nail tip body 1 (see below for specific meaning) is 5.4mm; the outer height D of the front edge of the nail tip body 1 (see below for specific meaning) is 6.2mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm; the width F of the nail tip body 1 from outside to inside (see below for specific meaning) is 15mm.

[0030] From Table 1 above, we can see that: the five experimental groups 1 to 5 are the same nail pieces, corresponding to the nail pieces with an inner height A of 4.4mm at the back edge. The comfort scores of these five groups are relatively high, with an average score of 92.2 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with an inner height A of 1.5mm at the back edge. The comfort scores of these five groups are also relatively high, with an average score of 91.8 points; the two control groups 11 and 12 are the same nail pieces, corresponding to the nail pieces with an inner height A of 5.68mm at the back edge. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 76 points; the two control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with an inner height A of 1.34mm at the back edge. The comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 78 points. In summary, in this embodiment, the nail tips with a rear edge inner height A of 1.5mm and 4.4mm are more comfortable than the nail tips with a rear edge inner height A of 5.68mm and 1.34mm; in other embodiments, the nail tips with a rear edge inner height A of 1.5mm to 4.4mm are more comfortable after being pasted on the surface of human nails.

[0031] The comfort of nail art nails is not only greatly affected by the value of the inner height A of the back edge of the nail piece body 1, but also by multiple parameters such as the outer height B of the back edge of the nail piece body 1, the inner height C of the front edge, the outer height D of the front edge of the nail piece body 1, the total length E of the nail piece body 1 in the front-to-back direction, and the width F of the nail piece body 1. These parameters have a slightly smaller impact than the inner height A of the back edge. These parameters will be experimented one by one below.

[0032] See Figure 3The height of the highest point 1211 of the rear bottom surface 121 of the nail plate body 1 is the rear edge outer height B of the nail plate body 1. In order to test the difference in comfort brought by different values ​​of the rear edge outer height B of the nail plate body 1, the following Table 2 is obtained through experiments:

[0033]

[0034]

[0035] Note: In the 14 groups of data given in Table 2 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on the nail tips with corresponding values. Except for the different values ​​of the outer height B of the rear edge of the nail tip body 1, the other parameters of the tried-on nail tips are the same: the inner height A of the rear edge of the nail tip body 1 is 4.4mm; the inner height C of the front edge of the nail tip body 1 (see below for specific meaning) is 5.4mm; the outer height D of the front edge of the nail tip body 1 (see below for specific meaning) is 6.2mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm; the width F of the nail tip body 1 from outside to inside (see below for specific meaning) is 15mm.

[0036] From Table 2 above, we can know that: the five experimental groups 1 to 5 are the same nail pieces, corresponding to the nail pieces with a rear edge outer height B of 4.6mm. The comfort scores of these five groups are relatively high, with an average score of 92.2 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with a rear edge outer height B of 1.7mm. The comfort scores of these five groups are also relatively high, with an average score of 91.8 points; the two control groups 11 and 12 are the same nail pieces, corresponding to the nail pieces with a rear edge outer height B of 5.74mm. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 81.5 points; the two control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with a rear edge outer height B of 1.49mm. The comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 81 points. In summary, in this embodiment, the nail tips with a rear edge outer height B of 1.7mm and 4.6mm are more comfortable than the nail tips with a rear edge outer height B of 5.74mm and 1.49mm; in other embodiments, the nail tips with a rear edge outer height B of 1.7mm to 4.6mm are more comfortable after being pasted on the surface of human nails.

[0037] In addition, the difference between the rear edge outer height B and the rear edge inner height A (the rear edge outer height B is always higher than the rear edge inner height A) also affects the comfort of the nail art. In order to test the difference in comfort caused by different differences between the rear edge outer height B and the rear edge inner height A, the following Table 3 is obtained through experiments:

[0038]

[0039]

[0040] Note: In the 14 groups of data given in Table 3 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on the nail tips with corresponding values. Except for the different values ​​of the inner height A of the rear edge of the nail tip body 1 and the different values ​​of the outer height B of the rear edge of the nail tip body 1 (that is, the difference between the outer height B of the rear edge and the inner height A of the rear edge is different), the other parameters of the tried-on nail tips are the same: the inner height C of the front edge of the nail tip body 1 (see below for specific meaning) is 5.4mm; the outer height D of the front edge of the nail tip body 1 (see below for specific meaning) is 6.2mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm; the width F of the nail tip body 1 from outside to inside (see below for specific meaning) is 15mm.

[0041] From Table 3 above, we can see that the two groups of experimental groups 1 and 2 are the same nail pieces, corresponding to the nail piece body 1 rear edge inner height A of 1.5mm, the nail piece body 1 rear edge outer height B of 1.7mm, and the difference between the rear edge outer height B and the rear edge inner height A is 0.2mm. The comfort scores of these two groups are high, with an average score of 90.5 points; the two groups of experimental groups 3 and 4 are the same nail pieces, corresponding to the nail piece body 1 rear edge inner height A of 1.6mm, the nail piece body 1 rear edge outer height B of 1.7mm, and the difference between the rear edge outer height B and the rear edge inner height A is 0.1mm The comfort scores of these two groups were high, with an average score of 92.5 points; the two groups of experimental groups 5 and 6 were the same nail tips, corresponding to the nail tip body 1 rear edge inner height A of 1.8mm, the nail tip body 1 rear edge outer height B of 2.0mm, and the difference between the rear edge outer height B and the rear edge inner height A of 0.2mm. The comfort scores of these two groups were high, with an average score of 91.5 points; the two groups of experimental groups 7 and 8 were the same nail tips, corresponding to the nail tip body 1 rear edge inner height A of 1.9mm, the nail tip body 1 rear edge outer height B of 2.0mm, and the rear edge The difference between the outer height B and the inner height A of the back edge is 0.1mm. The comfort scores of these two groups are relatively high, with an average score of 92 points. The two groups of experimental groups 9 and 10 are the same nail pieces, corresponding to the inner height A of the back edge of the nail piece body 1 of 4.4mm, the outer height B of the back edge of the nail piece body 1 of 4.6mm, and the difference between the outer height B of the back edge and the inner height A of the back edge of 0.2mm. The comfort scores of these two groups are relatively high, with an average score of 90.5 points. The two groups of control groups 11 and 12 are the same nail pieces, corresponding to the inner height A of the back edge of the nail piece body 1 of 1.5 The comfort scores of the two groups were lower than those of the experimental group, with an average score of only 87 points; the control groups 13 and 14 were the same nail tips, corresponding to the nail tip body 1 with an inner height A of 4.2mm at the back edge, the nail tip body 1 with an outer height B of 4.6mm at the back edge, and the difference between the outer height B at the back edge and the inner height A at the back edge being 0.4mm. The comfort scores of these two groups were also lower than those of the experimental group, with an average score of only 86.5 points.

[0042] In summary, for a nail art nail tip with a back edge inner height A of 1.5mm to 4.4mm and a back edge outer height B of 1.7mm to 4.6mm, the difference between the back edge outer height B and the back edge inner height A (i.e., the value of the back edge outer height B being higher than the back edge inner height A) is preferably 0.1mm to 0.2mm. Such a nail art nail tip has better comfort.

[0043] See Figure 4 , the front edge 112 of the back side 11 of the nail plate body 1 (combined with Figure 6 ) The highest point 1121 is suspended above the horizontal plane on which it is placed, and the height of the highest point 1121 of the front edge 112 is the front inner height C. In order to test the difference in comfort brought about by different values ​​of the front inner height C of the nail piece body 1, the following Table 4 is obtained through experiments:

[0044] Serial number Specific value of the inner height C of the front edge of the nail body 1 Comfort rating Experimental Group 1 5.4mm 92 Experimental Group 2 5.4mm 94 Experimental Group 3 5.4mm 94 Experimental Group 4 5.4mm 93 Experimental Group 5 5.4mm 92 Experimental Group 6 0.2mm 91 Experimental Group 7 0.2mm 92 Experimental Group 8 0.2mm 92 Experimental Group 9 0.2mm 93 Experimental Group 10 0.2mm 93 Control group 11 6.55mm 80 Control group 12 6.55mm 82 Control group 13 0.13mm 81 Control group 14 0.13mm 80

[0045] Note: In the 14 groups of data given in Table 4 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on nail tips with corresponding values. Except for the different values ​​of the inner height C of the front edge of the nail tip body 1, the other parameters of the tried-on nail tips are the same: the inner height A of the rear edge of the nail tip body 1 is 4.4mm; the outer height B of the rear edge of the nail tip body 1 is 4.6mm; the outer height D of the front edge of the nail tip body 1 (see below for specific meaning) is 6.2mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm; the width F of the nail tip body 1 from outside to inside (see below for specific meaning) is 15mm.

[0046] From Table 4 above, it can be seen that the five experimental groups 1 to 5 are the same nail pieces, corresponding to the nail pieces with an inner height C of 5.4mm at the front edge of the nail piece body 1. The comfort scores of these five groups are relatively high, with an average score of 93 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with an inner height C of 0.2mm at the front edge of the nail piece body 1. The comfort scores of these five groups are also relatively high, with an average score of 92.2 points; the two control groups 11 and 12 are the same nail pieces, corresponding to the nail pieces with an inner height C of 6.55mm at the front edge of the nail piece body 1. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 81 points; the two control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with an inner height C of 0.13mm at the front edge of the nail piece body 1. The comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 80.5 points. In summary, in this embodiment, the nail tips with an inner height C of 0.2mm and 5.4mm on the front edge of the nail tip body 1 are more comfortable than the nail tips with an inner height C of 0.13mm and 6.55mm on the front edge. In other embodiments, the nail tips with an inner height C of 0.2mm to 5.4mm on the front edge of the nail tip body 1 are more comfortable after being pasted on the surface of human nails.

[0047] See Figure 4 and Figure 5 , the front surface 122 of the nail plate body 1 (combined with Figure 6 ) The highest point 1221 is suspended above the horizontal plane on which it is placed, and the height of the highest point 1221 is the front outer height D (see Figure 5 ). In order to test the difference in comfort brought by different values ​​of the front edge outer height D of the nail plate body 1, the following Table 5 was obtained through experiments:

[0048] Serial number Specific value of the front edge height D of the nail body 1 Comfort rating Experimental Group 1 6.2mm 94 Experimental Group 2 6.2mm 92 Experimental Group 3 6.2mm 90 Experimental Group 4 6.2mm 93 Experimental Group 5 6.2mm 93 Experimental Group 6 0.5mm 94 Experimental Group 7 0.5mm 91 Experimental Group 8 0.5mm 93 Experimental Group 9 0.5mm 92 Experimental Group 10 0.5mm 94 Control group 11 7.38mm 80 Control group 12 7.38mm 82 Control group 13 0.28mm 81 Control group 14 0.28mm 81

[0049] Note: In the 14 groups of data given in Table 5 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on nail tips with corresponding values. Except for the different values ​​of the outer height D of the front edge of the nail tip body 1, the other parameters of the tried-on nail tips are the same: the inner height A of the rear edge of the nail tip body 1 is 4.4mm; the outer height B of the rear edge of the nail tip body 1 is 4.6mm; the inner height C of the front edge of the nail tip body 1 is 5.4mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm; the width F of the nail tip body 1 (see below for specific meaning) is 15mm.

[0050] From Table 5 above, we can know that the five experimental groups 1 to 5 are the same nail pieces, corresponding to the nail piece body 1 front edge outer height D of 6.2mm, and the comfort scores of these five groups are relatively high, with an average score of 92.4 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail piece body 1 front edge outer height D of 0.5mm, and the comfort scores of these five groups are also relatively high, with an average score of 92.8 points; the control groups 11 and 12 are the same nail pieces, corresponding to the nail piece body 1 front edge outer height D of 7.38mm, and the comfort scores of these two groups are lower than those of the experimental group, with an average score of only 80.5 points; the control groups 13 and 14 are the same nail pieces, corresponding to the nail piece body 1 front edge outer height D of 0.28mm, and the comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 80 points. In summary, in this embodiment, the nail tips with a front edge outer height D of 0.5mm and 6.2mm are more comfortable than the nail tips with a front edge outer height D of 0.28mm and 7.38mm; in other embodiments, the nail tips with a front edge outer height D of 0.5mm to 6.2mm are more comfortable after being pasted on the surface of human nails.

[0051] In addition, the difference between the front outer height D and the front inner height C (the front outer height D is always higher than the front inner height C) also affects the comfort of the nail art. In order to test the difference in comfort caused by different differences between the front outer height D and the front inner height C, the following Table 6 is obtained in the experiment:

[0052]

[0053]

[0054] Note: In the 14 groups of data given in Table 6 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on nail tips with corresponding values. Except for the different values ​​of the inner height C of the front edge of the nail tip body 1 and the different values ​​of the outer height D of the front edge of the nail tip body 1 (that is, the difference between the outer height D of the front edge and the inner height C of the front edge is different), the other parameters of the tried nail tips are the same: the inner height A of the rear edge of the nail tip body 1 is 4.4mm; the outer height B of the rear edge of the nail tip body 1 is 4.6mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm; the width F of the nail tip body 1 from outside to inside (see below for the specific meaning) is 15mm.

The two experimental groups 9 and 10 are the same nail tips, corresponding to the nail tip body 1 inner height C of the front edge is 5.4mm, the nail tip body 1 outer height D of the front edge is 6.2mm, and the difference between the outer height D of the front edge and the inner height C of the front edge is 0.8mm. The comfort scores of these two groups are relatively high, with an average score of 90 points. The two control groups 11 and 12 are the same nail tips, corresponding to the nail tip body 1 inner height C of the front edge is 0.4mm, The comfort scores of the nail tips with the front outer height D of the nail tip body 1 being 0.5mm and the difference between the front outer height D and the front inner height C being 0.1mm were lower than those of the experimental group, with an average score of only 86.5 points; the control groups 13 and 14 were the same nail tips, corresponding to the nail tips with the front inner height C of the nail tip body 1 being 5.2mm, the front outer height D of the nail tip body 1 being 6.2mm, and the difference between the front outer height D and the front inner height C being 1.0mm. The comfort scores of these two groups were also lower than those of the experimental group, with an average score of only 85.5 points.

[0056] In summary, for a nail art nail tip with a front inner height C of 0.2mm to 5.4mm and a front outer height D of 0.5mm to 6.2mm, the difference between the front outer height D and the front inner height C (that is, the value of the front outer height D being higher than the front inner height C) is preferably 0.3mm to 0.8mm. Such a nail art nail tip has better comfort.

[0057] The total length E of the test nail body 1 in the front-to-back direction (see Figure 7 ) The comfort differences caused by different values ​​are shown in Table 7 below:

[0058] Serial number Specific value of the total length E of the nail plate body 1 in the front-to-back direction Comfort rating Experimental Group 1 34mm 94 Experimental Group 2 34mm 92 Experimental Group 3 34mm 90 Experimental Group 4 34mm 92 Experimental Group 5 34mm 93 Experimental Group 6 12.5mm 94 Experimental Group 7 12.5mm 91 Experimental Group 8 12.5mm 93 Experimental Group 9 12.5mm 92 Experimental Group 10 12.5mm 94 Control group 11 37.68mm 81 Control group 12 37.68mm 80 Control group 13 10.2mm 80 Control group 14 10.2mm 80

[0059] Note: In the 14 groups of data given in Table 7 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on the nail tips with corresponding values. Except for the total length E of the nail tip body 1 in the front-to-back direction, the other parameters of the tried-on nail tips are the same: the inner height A of the rear edge of the nail tip body 1 is 4.4mm; the outer height B of the rear edge of the nail tip body 1 is 4.6mm; the inner height C of the front edge of the nail tip body 1 is 5.4mm; the outer height D of the front edge of the nail tip body 1 is 6.2mm; the width F from the outside to the outside of the nail tip body 1 (see below for the specific meaning) is 15mm.

[0060] From Table 7 above, it can be seen that the five experimental groups 1 to 5 are the same nail pieces, corresponding to the nail pieces with a total length E of 34 mm in the front-to-back direction of the nail piece body 1. The comfort scores of these five groups are relatively high, with an average score of 92.8 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with a total length E of 12.5 mm in the front-to-back direction of the nail piece body 1. The comfort scores of these five groups are also relatively high, with an average score of 92.2 points; the two control groups 11 and 12 are the same nail pieces, corresponding to the nail pieces with a total length E of 37.68 mm in the front-to-back direction of the nail piece body 1. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 80.5 points; the two control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with a total length E of 10.2 mm in the front-to-back direction of the nail piece body 1. The comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 80 points. In summary, in this embodiment, the nail tips with a total length E of 12.5 mm and 34 mm in the front-to-back direction are more comfortable than those with a total length E of 10.2 mm and 37.68 mm. In other embodiments, the nail tips with a total length E of 12.5 mm to 34 mm are more comfortable after being pasted to the surface of human nails.

[0061] See Figure 7 , the maximum width of the nail plate body 1 is the outer width F. In order to test the difference in comfort brought by different values ​​of the outer width F of the nail plate body 1, the following Table 8 is obtained through experiments:

[0062] Serial number Specific value of the width F from the outside of the nail body 1 Comfort rating Experimental Group 1 15mm 94 Experimental Group 2 15mm 93 Experimental Group 3 15mm 91 Experimental Group 4 15mm 95 Experimental Group 5 15mm 93 Experimental Group 6 6.5mm 93 Experimental Group 7 6.5mm 91 Experimental Group 8 6.5mm 91 Experimental Group 9 6.5mm 92 Experimental Group 10 6.5mm 93 Control group 11 17.49mm 79 Control group 12 17.49mm 80 Control group 13 6.03mm 82 Control group 14 6.03mm 78

[0063] Note: In the 14 groups of data given in Table 8 above, the full score of the comfort score is 100 points. Each group represents the comfort score given by an evaluator after trying on nail tips with corresponding values. Except for the different values ​​of the width F from the nail tip body 1, the other parameters of the tried-on nail tips are the same: the inner height A of the rear edge of the nail tip body 1 is 4.4mm; the outer height B of the rear edge of the nail tip body 1 is 4.6mm; the inner height C of the front edge of the nail tip body 1 is 5.4mm; the outer height D of the front edge of the nail tip body 1 is 6.2mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm.

[0064] From Table 8 above, it can be seen that the five experimental groups 1 to 5 are the same nail pieces, corresponding to the nail pieces with a width F of 15mm from the outside of the nail piece body 1. The comfort scores of these five groups are relatively high, with an average score of 93.2 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with a width F of 6.5mm from the outside of the nail piece body 1. The comfort scores of these five groups are also relatively high, with an average score of 92 points; the control groups 11 and 12 are the same nail pieces, corresponding to the nail pieces with a width F of 17.49mm from the outside of the nail piece body 1. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 79.5 points; the control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with a width F of 6.03mm from the outside of the nail piece body 1. The comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 80 points. In summary, in this embodiment, the nail tips with an outer width F of 6.5 mm and 15 mm are more comfortable than those with an outer width F of 6.03 mm and 17.49 mm. In other embodiments, the nail tips with an outer width F of 6.5 mm to 15 mm are more comfortable after being pasted on the surface of human nails.
