TECHNICAL FIELD

[0001] The utility model relates to a nail piece field, concretely relates to a comfortable nail piece and a nail piece assembly with the nail piece. BACKGROUND

[0002] The existing nail piece is usually designed to be shaped with the surface of human nail (standard nail type), wherein: the back of the nail piece is designed to be shaped with the surface of human nail, which is to make the back of the nail piece more closely combined with the surface of human nail after the nail piece is pasted to the surface of human nail (the back of the nail piece is pasted to the surface of human nail), so that the user has less foreign body sensation and feels more comfortable; the front of the nail piece is also designed to be shaped with the surface of human nail, which is to make the shaped front of the nail piece replace the surface of human nail after the nail piece is pasted to the surface of human nail, so that the visual effect is more natural and real.

[0003] The nail piece is pasted to the surface of human nail, which needs to first apply gel on the back of the nail piece, paste the back to the nail surface of the user to be manicured, and then irradiate the gel with UV light or the like to make it solidify, that is, the pasting is completed. The back of the nail piece cannot be completely shaped with the surface of human nail because the space for accommodating the gel needs to be additionally left out for the gel to be coated between the back of the nail piece and the surface of human nail; and moreover, the nail shape data of each person is slightly different from the standard nail type, so that even if the back of the nail piece is designed to be shaped with the surface of the nail of the standard nail type, it is not necessarily completely shaped with the surface of the nail of the user. Therefore, the user still feels a certain degree of discomfort after the nail piece is pasted to the surface of human nail. CONTENT OF THE UTILITY MODEL

[0004] The utility model solves the technical problem to provide a comfortable nail piece and a nail piece assembly with the nail piece, which can make the user feel more comfortable even if the back of the nail piece cannot be completely shaped with the surface of human nail after being pasted to the surface of human nail.

[0005] To solve the above problems, the utility model provides a comfortable nail piece, which comprises a nail piece body that can be placed horizontally on a horizontal plane, the back of the nail piece body is arched upward, and the rear edge of the back of the nail piece body is suspended above the placed horizontal plane, and the height of the highest point of the rear edge is 1.5mm-4.4mm.

DETAILED DESCRIPTION

[0025] The present invention will be further described in conjunction with the specific embodiments.

[0026] The nail assembly includes five nail art nails, which are not completely identical in size and are used to be pasted on the nail surfaces of the five fingers on the same palm of a person. Taking one of the five as an example, see Figure 1 , which includes a nail body 1, the nail body 1 is left-right symmetrical, and the back 11 is upwardly arched; the left side, right side and back side edge faces 12 of the nail body 1 are downwardly as the bottom face, and the nail body 1 can be placed horizontally on a horizontal plane (i.e. the dotted line in the figure) by virtue of the left and right bottom faces (i.e. the left and right edge faces 12) as shown in Figure 2 , among the bottom faces, the back bottom face 121 (see Figure 3 ) will be suspended above the horizontal plane placed. The back 11 of the nail body 1 can be pasted on the nail surface of a person after being coated with gel, but because the back 11 of the nail body 1 cannot be completely shaped with the nail surface of the user, after being pasted on the nail surface of a person, it is easy to cause a certain degree of discomfort of the user.

[0027] The inventor found that under the condition that the back 11 of the nail body 1 cannot be completely shaped with the nail surface of a person, there are multiple factors affecting the comfort of the user after the nail art nail is pasted on the nail surface of a person, and the two factors of the shape of the back 11 of the nail art nail and the center of gravity of the nail art nail itself have greater influence on the comfort, and these two factors are affected by multiple subordinate factors such as the total length of the nail body 1, the edge height, the edge face height, etc., among which, the inner height A of the back edge (see Figure 2, the back edge 111 of the back surface 11 of the nail plate body 1 is suspended above the placed horizontal plane, and the inner height A of the back edge, i.e. the height of the highest point 1111 of the back edge 111 of the back surface 11 of the nail plate body 1, has a greater impact. To test the comfort difference brought by different values of the inner height A of the back edge of the nail plate body 1, the following Table 1 is obtained through experiments:

[0028] Serial number Specific value of inner height A of rear edge of body 1 of a piece Comfort score 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, and each group represents the comfort evaluation score given by a tester after trying on the nail plate with the corresponding value. The nail plate tried on is the same in other parameters except that the inner height A of the back edge of the nail plate body 1 is different: the outer height B of the back edge of the nail plate body 1 (see below for specific meaning) is 4.6 mm; the inner height C of the front edge of the nail plate body 1 (see below for specific meaning) is 5.4 mm; the outer height D of the front edge of the nail plate body 1 (see below for specific meaning) is 6.2 mm; the total length E of the nail plate body 1 in the front-back direction is 34 mm; and the outer width F of the nail plate body 1 (see below for specific meaning) is 15 mm.

[0030] From Table 1 above, it can be seen that: the five groups of experimental group 1-5 are the same nail plate, corresponding to the nail plate with an inner height A of the back edge of 4.4 mm, and the comfort scores of these five groups are all high, with an average score of 92.2; the five groups of experimental group 6-10 are the same nail plate, corresponding to the nail plate with an inner height A of the back edge of 1.5 mm, and the comfort scores of these five groups are also high, with an average score of 91.8; the two groups of control group 11 and 12 are the same nail plate, corresponding to the nail plate with an inner height A of the back edge of 5.68 mm, and the comfort scores of these two groups are lower than those of the experimental groups, with an average score of only 76; the two groups of control group 13 and 14 are the same nail plate, corresponding to the nail plate with an inner height A of the back edge of 1.34 mm, and the comfort scores of these two groups are also lower than those of the experimental groups, with an average score of only 78. In summary, in this embodiment, the comfort of the nail plate with an inner height A of the back edge of 1.5 mm and 4.4 mm is better than that of the nail plate with an inner height A of the back edge of 5.68 mm and 1.34 mm; in other embodiments, the nail plate with an inner height A of the back edge of 1.5 mm-4.4 mm is comfortable after being attached to the surface of a human nail.

[0031] The comfort of the nail plate is not only greatly affected by the value of the inner height A of the back edge of the nail plate body 1, but also by the outer height B of the back edge of the nail plate body 1, the inner height C of the front edge of the nail plate body 1, the outer height D of the front edge of the nail plate body 1, the total length E of the nail plate body 1 in the front-back direction, and the outer width F of the nail plate body 1. These parameters have a slightly smaller impact than the inner height A of the back edge, and these parameters will be tested one by one in the following.

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

[0033]

[0034]

[0035] Note: In the 14 groups of data given in Table 2 above, the comfort score is 100 points, and each group represents the comfort evaluation score given by a tester after trying on the corresponding value of the manicure nail plate. The manicure nail plate tried on is the same except that the outer height B of the back edge of the nail plate body 1 is different: the inner height A of the back edge of the nail plate body 1 is 4.4 mm; the inner height C of the front edge of the nail plate body 1 (see below for specific meaning) is 5.4 mm; the outer height D of the front edge of the nail plate body 1 (see below for specific meaning) is 6.2 mm; the total length E of the nail plate body 1 in the front-back direction is 34 mm; and the outer width F of the nail plate body 1 (see below for specific meaning) is 15 mm.

[0036] From Table 2 above, it can be seen that: the five groups of experiments 1-5 are the same nail plate, corresponding to the manicure nail plate with an outer height B of 4.6 mm of the back edge, and the comfort scores of these five groups are relatively high, with an average score of 92.2; the five groups of experiments 6-10 are the same nail plate, corresponding to the manicure nail plate with an outer height B of 1.7 mm of the back edge, and the comfort scores of these five groups are also relatively high, with an average score of 91.8; the two groups of control groups 11 and 12 are the same nail plate, corresponding to the manicure nail plate with an outer height B of 5.74 mm of the back edge, and the comfort scores of these two groups are lower than those of the experimental groups, with an average score of only 81.5; the two groups of control groups 13 and 14 are the same nail plate, corresponding to the manicure nail plate with an outer height B of 1.49 mm of the back edge, and the comfort scores of these two groups are also lower than those of the experimental groups, with an average score of only 81. In summary, in this embodiment, the comfort of the manicure nail plate with an outer height B of 1.7 mm and 4.6 mm of the back edge is better than that of the manicure nail plate with an outer height B of 5.74 mm and 1.49 mm of the back edge; in other embodiments, the manicure nail plate with an outer height B of 1.7 mm to 4.6 mm of the back edge is relatively comfortable after being attached to the surface of a human finger.

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

[0038]

[0039]

[0040] Note: In the 14 groups of data given in Table 3 above, the comfort score is full marks 100, each group represents a comfort evaluation score given by a tester after trying on the corresponding nail plate, the nail plate tried on is the same except that the back edge inner height A of the nail plate body 1 is different, the back edge outer height B of the nail plate body 1 is different (i.e. the difference between the back edge outer height B and the back edge inner height A is different), and the rest of the parameters are the same: the front edge inner height C of the nail plate body 1 (see below for specific meaning) is 5.4 mm; the front edge outer height D of the nail plate body 1 (see below for specific meaning) is 6.2 mm; the total length E of the nail plate body 1 in the front-back direction is 34 mm; the width F from the outside of the nail plate body 1 (see below for specific meaning) is 15 mm.

[0041] From Table 3 above: Experimental groups 1 and 2 are the same nail plate, corresponding to the nail plate body 1 back edge inner height A of 1.5 mm, the nail plate body 1 back edge outer height B of 1.7 mm, and the difference between the back edge outer height B and the back edge inner height A of 0.2 mm, the comfort scores of these two groups are relatively high, with an average score of 90.5; Experimental groups 3 and 4 are the same nail plate, corresponding to the nail plate body 1 back edge inner height A of 1.6 mm, the nail plate body 1 back edge outer height B of 1.7 mm, and the difference between the back edge outer height B and the back edge inner height A of 0.1 mm, the comfort scores of these two groups are relatively high, with an average score of 92.5; Experimental groups 5 and 6 are the same nail plate, corresponding to the nail plate body 1 back edge inner height A of 1.8 mm, the nail plate body 1 back edge outer height B of 2.0 mm, and the difference between the back edge outer height B and the back edge inner height A of 0.2 mm, the comfort scores of these two groups are relatively high, with an average score of 91.5; Experimental groups 7 and 8 are the same nail plate, corresponding to the nail plate body 1 back edge inner height A of 1.9 mm, the nail plate body 1 back edge outer height B of 2.0 mm, and the difference between the back edge outer height B and the back edge inner height A of 0.1 mm, the comfort scores of these two groups are relatively high, with an average score of 92; Experimental groups 9 and 10 are the same nail plate, corresponding to the nail plate body 1 back edge inner height A of 4.4 mm, the nail plate body 1 back edge outer height B of 4.6 mm, and the difference between the back edge outer height B and the back edge inner height A of 0.2 mm, the comfort scores of these two groups are relatively high, with an average score of 90.5; Control groups 11 and 12 are the same nail plate, corresponding to the nail plate body 1 back edge inner height A of 1.5 mm, the nail plate body 1 back edge outer height B of 2.0 mm, and the difference between the back edge outer height B and the back edge inner height A of 0.5 mm, the comfort scores of these two groups are relatively low compared to the experimental groups, with an average score of only 87; Control groups 13 and 14 are the same nail plate, corresponding to the nail plate body 1 back edge inner height A of 4.2 mm, the nail plate body 1 back edge outer height B of 4.6 mm, and the difference between the back edge outer height B and the back edge inner height A of 0.4 mm, the comfort scores of these two groups are also relatively low compared to the experimental groups, with an average score of only 86.5.

[0042] In summary, the nail plate with the trailing edge inner height A of 1.5 mm to 4.4 mm and the trailing edge outer height B of 1.7 mm to 4.6 mm, preferably the difference between the trailing edge outer height B and the trailing edge inner height A (i.e. the value of the trailing edge outer height B higher than the trailing edge inner height A) of 0.1 mm to 0.2 mm, has better comfort.

[0043] See Figure 4 The highest point 1121 of the front edge 112 of the back surface 11 of the nail plate body 1 (in combination with Figure 6 ) 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 edge inner height C. In order to test the difference in comfort brought by different values of the front edge inner height C of the nail plate body 1, the following Table 4 is obtained through experiments:

[0044] Serial number Specific value of inner height C of front edge of body 1 of a piece Comfort score 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 comfort evaluation is 100 points, and each group represents the comfort evaluation score given by a tester after trying on the nail plate with the corresponding value. The nail plate tried on is the same in other parameters except for the value of the front edge inner height C of the nail plate body 1: the trailing edge inner height A of the nail plate body 1 is 4.4 mm; the trailing edge outer height B of the nail plate body 1 is 4.6 mm; the front edge outer height D (see below for specific meaning) of the nail plate body 1 is 6.2 mm; the total length E of the nail plate body 1 in the front-to-back direction is 34 mm; and the outer width F (see below for specific meaning) of the nail plate body 1 is 15 mm.

[0046] From Table 4 above, it can be seen that: the five groups of experimental group 1 to 5 are the same nail plate, corresponding to the nail plate with the front edge inner height C of the nail plate body 1 of 5.4 mm, and the comfort evaluation scores of these five groups are all high, with an average score of 93 points; the five groups of experimental group 6 to 10 are the same nail plate, corresponding to the nail plate with the front edge inner height C of the nail plate body 1 of 0.2 mm, and the comfort evaluation scores of these five groups are also high, with an average score of 92.2 points; the two groups of control group 11 and 12 are the same nail plate, corresponding to the nail plate with the front edge inner height C of the nail plate body 1 of 6.55 mm, and the comfort evaluation scores of these two groups are lower than those of the experimental groups, with an average score of only 81 points; the two groups of control group 13 and 14 are the same nail plate, corresponding to the nail plate with the front edge inner height C of the nail plate body 1 of 0.13 mm, and the comfort evaluation scores of these two groups are also lower than those of the experimental groups, with an average score of only 80.5 points. In summary, in this embodiment, the nail plate with the front edge inner height C of the nail plate body 1 of 0.2 mm and 5.4 mm has better comfort than the nail plate with the front edge inner height C of the nail plate body 1 of 0.13 mm and 6.55 mm; in other embodiments, the nail plate with the front edge inner height C of the nail plate body 1 of 0.2 mm to 5.4 mm has good comfort after being attached to the surface of a human nail.

[0047] See Figure 4 andFigure 5 The front surface 122 of the armor plate body 1 (combined with) Figure 6 The highest point 1221 is suspended above the horizontal plane on which it is placed; the height of this highest point 1221 is the outer height D of the front edge (see...). Figure 5 To test the comfort differences resulting from different values ​​of the outer edge height D of the armor plate body 1, the following table shows the experimental results:

[0048] Serial number Specific value of outer height D of front edge of body 1 of a piece Comfort score 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 sets of data given in Table 5 above, the comfort score is out of 100. Each set represents the comfort score given by a tester after trying on the corresponding nail art pieces. Except for the difference in the outer height D of the front edge of the nail art piece 1, the other parameters of the nail art pieces tried on are the same: the inner height A of the back edge of the nail art piece 1 is 4.4mm; the outer height B of the back edge of the nail art piece 1 is 4.6mm; the inner height C of the front edge of the nail art piece 1 is 5.4mm; the total length E of the nail art piece 1 in the front-to-back direction is 34mm; and the outer width F of the nail art piece 1 (see below for specific meaning) is 15mm.

[0050] As shown in Table 5 above: Experimental groups 1-5 used the same nail tips, corresponding to nail tips with an outer edge height (D) of 6.2mm. These five groups all had high comfort scores, with an average score of 92.4. Experimental groups 6-10 also used the same nail tips, corresponding to nail tips with an outer edge height (D) of 0.5mm. These five groups also had high comfort scores, with an average score of 92.8. Control groups 11 and 12 used the same nail tips, corresponding to nail tips with an outer edge height (D) of 7.38mm. These two groups had lower comfort scores compared to the experimental groups, with an average score of only 80.5. Control groups 13 and 14 used the same nail tips, corresponding to nail tips with an outer edge height (D) of 0.28mm. These two groups also had lower comfort scores compared to the experimental groups, with an average score of only 80. In summary, in this embodiment, the nail art pieces with an outer edge height D of 0.5mm and 6.2mm are more comfortable than those with an outer edge height D of 0.28mm and 7.38mm. In other embodiments, nail art pieces with an outer edge height D of 0.5mm to 6.2mm are generally more comfortable after being applied to the surface of the nail.

[0051] Furthermore, the difference between the outer edge height D and the inner edge height C (the outer edge height D is always higher than the inner edge height C) also affects the comfort of nail art. To test the comfort differences caused by different differences between the outer edge height D and the inner edge height C, the experiment yielded the following Table 6:

[0052]
