Description

Technical Field

[0001] The invention relates to the field of nail art sheets, and in particular to a nail art sheet with high comfort and a nail art sheet assembly having the nail art sheet. Background Art

[0002] Modern nail art tips are usually designed based on the standard shape of human nails to ensure that the back of the nail art tip can closely fit the surface contour of the natural nail. This contour design is designed to make the nail art tip seamlessly fit the real nail after being attached, thereby reducing the foreign body sensation and improving the wearer's comfort. At the same time, the front of the nail art tip is also carefully designed to simulate the appearance of natural nails, so that once attached, the overall visual effect appears natural and realistic.

[0003] In order to fix the nail art piece to the surface of the human nail, a layer of special gel needs to be applied to the back of the nail art piece, and then UV light is used to harden the gel to achieve a firm adhesion. However, due to the presence of the gel layer, the back of the nail art piece cannot completely fit the surface of the user's nail, and a certain amount of space must be reserved to accommodate the gel. In addition, different people's nails have different specific shapes, and not everyone's nails conform to the so-called "standard" nail shape. Even if the nail art piece is designed according to the idealized standard nail shape size, it cannot perfectly fit the nail curve of every customer, and the wearer may still feel a certain degree of discomfort. Summary of the invention

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

[0005] To solve the above problems, the present invention provides a nail art piece with high comfort, comprising a nail piece body that can be placed flat on a horizontal plane, the back of the nail piece body is arched upward, and the maximum width of the back of the nail piece body is 6.1mm to 14.6mm.

[0006] Furthermore, the outer width of the nail plate body is 6.5 mm to 15 mm.

[0007] Furthermore, the outer width is 0.4 mm to 0.8 mm wider than the maximum width of the back side of the nail piece body.

[0008] Furthermore, the maximum width of the front surface of the nail plate body is 0 or 3.6 mm to 13.6 mm.

[0009] Furthermore, the maximum width of the front edge of the back side of the nail piece body is 0 or 2.2 mm to 12.0 mm.

[0010] Furthermore, the maximum width of the front surface of the nail plate body is 0 or 3.6mm to 13.6mm, and when the maximum width of the front surface of the nail plate body is not 0mm, it is 1.4mm to 1.6mm wider than the maximum width of the front edge of the back surface of the nail plate 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] A nail plate assembly is also provided, comprising a plurality of nail plates of different sizes, wherein at least one nail plate is the aesthetic nail plate as described above.

[0013] Furthermore, the nail art sheets have at least two pieces, and the sizes are not completely the same. The ratio of the maximum width of the front surface of the nail sheet body to the outer width of the nail sheet body of all the nail art sheets is the same.

[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 maximum width of the back of the nail sheet of the present invention is 6.1mm to 14.6mm. Even if the back of the nail sheet cannot completely conform to the surface of the human nail, it has been verified by experiments that the nail sheet can make the user feel more comfortable after being pasted on the surface of the human nail.

[0022] The present invention is further described in detail below in conjunction with specific implementation methods.

[0023] 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 10 of the nail plate body 1 face downward as the bottom surface, and the nail plate body 1 can be as 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.

[0024] 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 and width of the nail plate body 1. Among them, the width A (see FIG. Figure 2 The maximum width of the back side 11 of the nail plate body 1 in the left and right direction is the inner width A) which has a greater impact. In order to test the difference in comfort brought by different values ​​of the inner width A of the nail plate body 1, the following table 1 is obtained through experiments:

[0025]

[0026]

[0027] Note: In the 14 groups of data given in Table 1 above, the full score for comfort rating is 100 points. Each group represents the comfort rating given by an evaluator after trying on nail tips of corresponding values. Except for the different values ​​of the width A from the inside to the nail body 1, the other parameters of the tried-on nail tips are the same: the width B from the outside to the outside of the nail body 1 (see below for specific meaning) is 15mm; the outer width C of the front edge of the nail body 1 (see below for specific meaning) is 13.6mm; the inner width D of the front edge of the nail body 1 (see below for specific meaning) is 12.0mm; the total length E of the nail body 1 in the front-to-back direction is 34mm.

[0028] 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 width A of 14.6mm. The comfort scores of these five groups are relatively high, with an average score of 92.6 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with an inner width A of 6.1mm. The comfort scores of these five groups are also relatively high, with an average score of 91.6 points; the two control groups 11 and 12 are the same nail pieces, corresponding to the nail pieces with an inner width A of 16.76mm. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 76.5 points; the two control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with an inner width A of 4.75mm. The comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 77 points. In summary, in this embodiment, the nail art sheets with an inner width A of 6.1 mm and 14.6 mm are more comfortable than the nail art sheets with an inner width A of 16.76 mm and 4.75 mm; in other embodiments, the nail art sheets with an inner width A of 6.1 mm to 14.6 mm are more comfortable after being pasted on the surface of human nails.

[0029] The comfort of the nail piece is not only greatly affected by the value of the inner width A of the nail piece body 1, but also by multiple parameters such as the outer width B of the nail piece body 1, the outer width C of the front edge, the inner width D of the front edge of the nail piece body 1, and the total length E of the nail piece body 1 in the front-to-back direction. These parameters have a slightly smaller impact than the inner width A. These parameters will be experimented one by one below.

[0030] See Figure 2 , the maximum width of the nail plate body 1 in the left-right direction is the outer width B. In order to test the difference in comfort brought by different values ​​of the outer width B of the nail plate body 1, the following Table 2 is obtained through experiments:

[0031] Serial number Specific value of the width B of the nail plate 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

[0032] Note: In the 14 groups of data given in Table 2 above, the full score for comfort rating is 100 points. Each group represents the comfort rating given by an evaluator after trying on nail tips with corresponding values. Except for the different values ​​of the width B from the outside of the nail tip body 1, the other parameters of the tried-on nail tips are the same: the width A from the inside of the nail tip body 1 is 14.6mm; the outer width C of the front edge of the nail tip body 1 (see below for specific meaning) is 13.6mm; the inner width D of the front edge of the nail tip body 1 (see below for specific meaning) is 12.0mm; the total length E of the nail tip body 1 in the front-to-back direction is 34mm.

[0033] From Table 2 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 B 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 B 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 two control groups 11 and 12 are the same nail pieces, corresponding to the nail pieces with a width B 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 two control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with a width B 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 B of 6.5 mm and 15 mm are more comfortable than those with an outer width B of 6.03 mm and 17.49 mm. In other embodiments, the nail tips with an outer width B of 6.5 mm to 15 mm are more comfortable after being pasted on the surface of human nails.

[0034] In addition, the difference between the outer width B and the inner width A (the outer width B is always wider than the inner width A) also affects the comfort of the nail art. In order to test the difference in comfort caused by different differences between the outer width B and the inner width A, the following results were obtained in the experiment:

[0035] Table 3:

[0036]

[0037] 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 nail pieces with corresponding values. Except for the different values ​​of the inner width A of the nail piece body 1 and the different values ​​of the outer width B of the nail piece body 1 (that is, the difference between the outer width B and the inner width A is different), the other parameters of the tried-on nail pieces are the same: the outer width C of the front edge of the nail piece body 1 (see below for specific meaning) is 13.6mm; the inner width D of the front edge of the nail piece body 1 (see below for specific meaning) is 12.0mm; the total length E of the nail piece body 1 in the front-to-back direction is 34mm.

[0038] 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 inner width A of 6.1mm, the nail piece body 1 outer width B of 6.5mm, and the difference between the outer width B and the inner width A is 0.4mm. The comfort scores of these two groups are high, with an average score of 91 points; the two groups of experimental groups 3 and 4 are the same nail pieces, corresponding to the nail piece body 1 inner width A of 7.0mm, the nail piece body 1 outer width B of 7.5mm, and the difference between the outer width B and the inner width A is 0.5mm. The comfort scores of these two groups were high, with an average score of 91.5 points; the two groups of experimental groups 5 and 6 were the same nail pieces, corresponding to the nail piece body 1 inner width A of 8.4mm, the nail piece body 1 outer width B of 9.0mm, and the difference between the outer width B and the inner width A of 0.6mm. The comfort scores of these two groups were high, with an average score of 93 points; the two groups of experimental groups 7 and 8 were the same nail pieces, corresponding to the nail piece body 1 inner width A of 11.3mm, the nail piece body 1 outer width B of 12.0mm, and the difference between the outer width B and the inner width A of 0.6mm. The difference between the inner and the width A is 0.7mm. The comfort scores of these two groups are high, with an average score of 92 points. The experimental groups 9 and 10 are the same nail pieces, corresponding to the nail piece body 1 inner to width A of 14.2mm, the nail piece body 1 outer to width B of 15.0mm, and the difference between the outer width B and the inner width A of 0.8mm. The comfort scores of these two groups are high, with an average score of 90.5 points. The control groups 11 and 12 are the same nail pieces, corresponding to the nail piece body 1 inner to width A of 7.0mm, The nail tips with the outer width B of the nail tip body 1 being 7.2mm and the difference between the outer width B and the inner width A being 0.2mm had lower comfort scores than the experimental group, with an average score of only 86.5 points; the control groups 13 and 14 had the same nail tips, corresponding to the nail tip body 1 inner width A being 11.3mm, the nail tip body 1 outer width B being 12.5mm, and the difference between the outer width B and the inner width A being 1.2mm. The comfort scores of these two groups were also lower than the experimental group, with an average score of only 85.5 points.

[0039] In summary, for a nail art sheet with an inner width A of 6.1mm to 14.6mm and an outer width B of 6.5mm to 15mm, the difference between the outer width B and the inner width A (i.e., the value of the outer width B being wider than the inner width A) is preferably 0.4mm to 0.8mm. Such a nail art sheet has better comfort.

[0040] See Figure 3 , the maximum width of the front surface 12 of the nail piece body 1 in the left and right direction is the front outer width C. All nail pieces in the nail piece assembly have the same ratio of the front outer width C to the outer width B. In order to test the difference in comfort caused by different values ​​of the front outer width C of the nail piece body 1, the following Table 4 was obtained through experiments:

[0041]

[0042]

[0043] Note: In the 19 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 pieces with corresponding values. Except for the different values ​​of the outer width C of the front edge of the nail piece body 1, the other parameters of the tried-on nail pieces are the same: the width A from the inside to the nail piece body 1 is 14.6mm; the width B from the outside to the nail piece body 1 is 15mm; the inner width D of the front edge of the nail piece body 1 (see below for specific meaning) is 12.0mm; the total length E of the nail piece body 1 in the front-to-back direction is 34mm.

[0044] From Table 4 above, it can be seen that the five groups of experimental groups 1 to 5 are the same nail pieces, corresponding to the nail pieces with a front outer width C of 0 mm for the nail piece body 1 (at this time, the front edge 12 of the nail piece body 1 is pointed rather than flat), and the comfort scores of these five groups are relatively high, with an average score of 92 points; the five groups of experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with a front outer width C of 3.6 mm for the nail piece body 1, and the comfort scores of these five groups are also relatively high, with an average score of 91.6 points; the five groups of experimental groups 11 to 15 are the same nail pieces, corresponding to the nail pieces with a front outer width C of 13.6 mm for the nail piece body 1, and the comfort scores of these five groups are also relatively high, with an average score of 92.4 points;

[0045] The control groups 16 and 17 are the same nail pieces, corresponding to the nail piece body 1 front edge outer width C of 15.04mm. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 80 points; the control groups 18 and 19 are the same nail pieces, corresponding to the nail piece body 1 front edge outer width C of 0.53mm. The comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 84.5 points. In summary, the nail piece with a front edge outer width C of 0mm or 0.2mm to 5.4mm is more comfortable than the nail piece with a front edge outer width C of 0.53mm or 15.04mm after being pasted on the surface of human nails.

[0046] See Figure 4 , the maximum width of the front edge 111 of the back side 11 of the nail plate body 1 is the front inner width D. To test the difference in comfort brought by different values ​​of the front inner width D of the nail plate body 1, the following Table 5 is obtained through experiments:

[0047] Serial number Specific value of the inner width D of the front edge of the nail body 1 Comfort rating Experimental Group 1 0mm 92 Experimental Group 2 0mm 92 Experimental Group 3 0mm 93 Experimental Group 4 0mm 92 Experimental Group 5 0mm 93 Experimental Group 6 2.2mm 93 Experimental Group 7 2.2mm 90 Experimental Group 8 2.2mm 91 Experimental Group 9 2.2mm 93 Experimental Group 10 2.2mm 93 Experimental Group 11 12.0mm 93 Experimental Group 12 12.0mm 92 Experimental Group 13 12.0mm 91 Experimental Group 14 12.0mm 92 Experimental Group 15 12.0mm 93 Control group 16 13.72mm 81 Control group 17 13.72mm 81 Control group 18 2.06mm 86 Control group 19 2.06mm 84

[0048] Note: In the 19 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 pieces with corresponding values. Except for the different values ​​of the inner width D of the front edge of the nail piece body 1, the other parameters of the tried-on nail pieces are the same: the width A from the inside to the inside of the nail piece body 1 is 14.6mm; the width B from the outside to the outside of the nail piece body 1 is 15mm; the outer width C of the front edge of the nail piece body 1 is 13.6mm; the total length E of the nail piece body 1 in the front-to-back direction is 34mm.

[0049] From Table 5 above, we can see that the five groups of experimental groups 1 to 5 are the same nail pieces, corresponding to the nail pieces with an inner width D of 0 mm at the front edge of the nail piece body 1 (at this time, the front edge 12 of the nail piece body 1 is pointed rather than flat), and the comfort scores of these five groups are relatively high, with an average score of 92.4 points; the five groups of experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with an inner width D of 2.2 mm at the front edge of the nail piece body 1, and the comfort scores of these five groups are also relatively high, with an average score of 92 points; the five groups of experimental groups 11 to 15 are the same nail pieces, corresponding to the nail pieces with an inner width D of 2.2 mm at the front edge of the nail piece body 1. The five groups of nail art pieces with an inner width D of 12.0 mm also had relatively high comfort scores, with an average score of 92.2 points; the control groups 16 and 17 were the same nail art pieces, corresponding to nail art pieces with an inner width D of 13.72 mm at the front edge of the nail art piece body 1, and the comfort scores of these two groups were lower than those of the experimental group, with an average score of only 81 points; the control groups 18 and 19 were the same nail art pieces, corresponding to nail art pieces with an inner width D of 2.06 mm at the front edge of the nail art piece body 1, and the comfort scores of these two groups were also lower than those of the experimental group, with an average score of only 85 points. In summary, the nail art pieces with an inner width D of 0 mm or 2.2 mm to 12.0 mm at the front edge of the nail art piece body 1 are more comfortable after being pasted on the surface of human nails than nail art pieces with an inner width D of 2.06 mm or 13.72 mm at the front edge.

[0050] In addition, the difference between the front outer width C and the front inner width D (at this time, the front outer width C is not 0 mm, but is always greater than the front inner width D) also affects the comfort of the nail art piece. In order to test the difference in comfort caused by different differences between the front outer width C and the front inner width D, the following Table 6 is obtained in the experiment:

[0051]

[0052] Note: In the 14 groups of data given in Table 6 above, the full score for comfort rating is 100 points. Each group represents the comfort rating given by an evaluator after trying on nail pieces with corresponding values. Except for the different values ​​of the outer width C of the front edge of the nail piece body 1 and the inner width D of the front edge of the nail piece body 1 (i.e., the difference between the outer width C of the front edge and the inner width D of the front edge is different), the other parameters of the tried-on nail pieces are the same: the inner width A of the nail piece body 1 is 14.6mm; the outer width B of the nail piece body 1 is 15mm; the total length E of the nail piece body 1 in the front-to-back direction is 34mm.

[0053] From Table 6 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 front outer width C of 3.6mm, the nail piece body 1 front inner width D of 2.2mm, and the difference between the front outer width C and the front inner width D is 1.4mm. 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 front outer width C of 4.5mm, the nail piece body 1 front inner width D of 3.0mm, and the difference between the front outer width C and the front inner width D is 1.5mm 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 pieces, corresponding to the nail piece body 1 front outer width C of 7.5mm, the nail piece body 1 front inner width D of 6.0mm, and the difference between the front outer width C and the front inner width D of 1.5mm. The comfort scores of these two groups were high, with an average score of 93 points; the two groups of experimental groups 7 and 8 were the same nail pieces, corresponding to the nail piece body 1 front outer width C of 10.0mm, the nail piece body 1 front inner width D of 8.6mm, and the front outer width The difference between the front width C and the front inner width D is 1.4mm. The comfort scores of these two groups are relatively high, with an average score of 91 points. The experimental groups 9 and 10 are the same nail pieces, corresponding to the front outer width C of the nail piece body 1 is 13.6mm, the front inner width D of the nail piece body 1 is 12.0mm, and the difference between the front outer width C and the front inner width D is 1.6mm. The comfort scores of these two groups are relatively high, with an average score of 91.5 points. The control groups 11 and 12 are the same nail pieces, corresponding to the front outer width C of the nail piece body 1 is 3.6m m, nail pieces with an inner width D of 3.0mm at the front edge of the nail piece body 1 and a difference of 0.6mm between the outer width C of the front edge and the inner width D of 0.6mm. The comfort scores of these two groups were lower than those of the experimental group, with an average score of only 85 points. The control groups 13 and 14 were the same nail pieces, corresponding to nail pieces with an outer width C of 13.6mm at the front edge of the nail piece body 1, an inner width D of 11.6mm at the front edge of the nail piece body 1, and a difference of 2.0mm between the outer width C of the front edge and the inner width D of 2.0mm. The comfort scores of these two groups were also lower than those of the experimental group, with an average score of only 87.5 points.

[0054] In summary, for a nail art sheet with a front outer width C of 3.6mm to 13.6mm and a front inner width D of 2.2mm to 12.0mm, the difference between the front outer width C and the front inner width D (i.e., the value of the front inner width D being wider than the front outer width C) is preferably 1.4mm to 1.6mm. Such a nail art sheet has better comfort.

[0055] The total length E of the test nail plate body 1 in the front-to-back direction (see Figure 1 ) The difference in comfort caused by different values, the experiment results in the following Table 7:

[0056]

[0057]

[0058] Note: In the 14 groups of data given in Table 7 above, the full score for comfort rating is 100 points. Each group represents the comfort rating given by an evaluator after trying on nail tips of 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 width A from the inside to the outside of the nail tip body 1 is 14.6mm; the width B from the outside to the inside of the nail tip body 1 is 15mm; the outer width C of the front edge of the nail tip body 1 is 13.6mm; the inner width D of the front edge of the nail tip body 1 is 12.0mm.

[0059] 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.
