Description

Technical Field

[0001] The invention relates to the field of nail art sheets, and in particular to a comfortable nail art sheet 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 comfortable nail sheet and a nail sheet assembly having the nail sheet, 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 sheet cannot completely conform to the surface of the human nail.

[0005] To solve the above problems, the present invention provides a comfortable nail piece, 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 highest point of the back of the nail piece body is 2.1mm to 5.0mm.

[0006] Wherein, the maximum height of the nail piece body is 3.6mm to 6.5mm.

[0007] The outer maximum height is 1.0 mm to 1.5 mm higher than the highest point on the back of the nail plate body.

[0008] The distance between the highest point of the nail plate body and the rear end point of the nail plate body in the front-to-back direction is 7.2 mm to 10 mm.

[0009] Wherein, the total length of the nail plate body in the front-to-back direction is 12.5 mm to 34 mm.

[0010] 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.

[0011] There are at least two nail art sheets with different sizes, and the ratio of the highest point on the back of the nail sheet body to the outer height of all the nail art sheets is the same.

[0012] There are at least two nail art sheets, the sizes of which are not completely the same, and the ratio of the outer height to the total length of all the nail art sheets is the same.

[0013] There are at least two nail art pieces, and the sizes are not completely the same. In all nail art pieces, the ratio of the distance between the outer highest point of the nail piece body and the rear end point of the nail piece body in the front-to-back direction to the total length is the same.

[0014] There are five nail art sheets, which are respectively used to be pasted on the surfaces of the nails of five fingers on the same palm of a person.

[0015] Beneficial effect: The highest point height of the back of the nail plate body of the nail plate of the present invention is 2.1mm-5.0mm. Even if the back of the nail plate body cannot completely conform to the surface of the human nail, it has been verified by experiments that the nail plate can make the user feel more comfortable after being pasted on the surface of the human nail.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with specific implementation methods.

[0022] 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 1The 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 2 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.

[0023] 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. These two factors are in turn affected by multiple subordinate factors such as the total length, height, and distance from the highest point to the rear end point of the nail plate body 1. Among them, the highest point A (see FIG. 1 ) in the nail plate body 1 is the height of the nail plate body 1. Figure 2 The height of the highest point 111 of the back side 11 of the nail plate body 1 (ie, the inner maximum height A) has a greater impact. In order to test the difference in comfort caused by different values ​​of the inner maximum height A of the nail plate body 1, the following Table 1 is obtained through experiments:

[0024]

[0025]

[0026] 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 a nail piece with a corresponding value. Except for the different values ​​of the inner maximum height A of the nail piece body 1, the other parameters of the tried-on nail pieces are the same: the outer maximum height B of the nail piece body 1 (see below for specific meaning) is 6.5mm; the distance C between the outer maximum height B of the nail piece body 1 and the rear end point 13 of the nail piece body 1 in the front-to-back direction (see below for specific meaning) is 10mm; the total length D of the nail piece body 1 in the front-to-back direction is 34mm.

[0027] 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 maximum height A of 5.0mm. The comfort scores of these five groups are relatively high, with an average score of 91.6 points; the five experimental groups 6 to 10 are the same nail pieces, corresponding to the nail pieces with an inner maximum height A of 2.1mm. 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 an inner maximum height A of 5.78mm. The comfort scores of these two groups are lower than those of the experimental group, with an average score of only 75.5 points; the two control groups 13 and 14 are the same nail pieces, corresponding to the nail pieces with an inner maximum height A of 1.8mm. 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 art sheets with an inner maximum height A of 2.1mm and 5.0mm are more comfortable than the nail art sheets with an inner maximum height A of 5.78mm and 1.8mm; in other embodiments, the nail art sheets with an inner maximum height A of 2.1mm to 5.0mm are more comfortable after being pasted on the surface of human nails.

[0028] The comfort of a nail piece is not only greatly affected by the value of the inner maximum height A of the nail piece body 1, but also by multiple parameters such as the outer maximum height B of the nail piece body 1, the distance C between the outer maximum height B of the nail piece body 1 and the rear end point 13 of the nail piece body 1 in the front-to-back direction, and the total length D of the nail piece body 1 in the front-to-back direction. These parameters have a slightly smaller impact than the inner maximum height A, and these parameters will be experimented one by one below.

[0029] See Figure 2 , the height of the highest point 121 of the front face 12 of the nail plate body 1 (the distance between the highest point 121 of the front face 12 of the nail plate body 1 and the horizontal plane) is the outer height B of the nail plate body 1, and the highest point 121 is located at the center line of the nail plate body 1. In order to test the difference in comfort brought by different values ​​of the outer height B of the nail plate body 1, the following Table 2 is obtained in the experiment:

[0030] Serial number Specific value of the highest B outside the armor plate 1 Comfort rating Experimental Group 1 6.5mm 92 Experimental Group 2 6.5mm 93 Experimental Group 3 6.5mm 91 Experimental Group 4 6.5mm 92 Experimental Group 5 6.5mm 93 Experimental Group 6 3.6mm 93 Experimental Group 7 3.6mm 91 Experimental Group 8 3.6mm 91 Experimental Group 9 3.6mm 92 Experimental Group 10 3.6mm 93 Control group 11 7.67mm 83 Control group 12 7.67mm 81 Control group 13 2.38mm 82 Control group 14 2.38mm 82

[0031] 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 nail tip body 1, the other parameters of the tried-on nail tips are the same: the inner height A of the nail tip body 1 is 5.0mm; the distance C (specific meaning see below) between the outer height B of the nail tip body 1 and the rear end point 13 of the nail tip body 1 in the front-to-back direction is 10mm; the total length D of the nail tip body 1 in the front-to-back direction is 34mm.

[0032] From Table 2 above, we can see that: the five experimental groups 1 to 5 have the same nail tips, corresponding to the outer-highest nail tips of 6.5mm, and 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 have the same nail tips, corresponding to the outer-highest nail tips of 3.6mm, and 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 have the same nail tips, corresponding to the outer-highest nail tips of 7.67mm, and the comfort scores of these two groups are lower than those of the experimental group, with an average score of only 82 points; the two control groups 13 and 14 have the same nail tips, corresponding to the outer-highest nail tips of 2.38mm, and the comfort scores of these two groups are also lower than those of the experimental group, with an average score of only 82 points. In summary, in this embodiment, the nail tips with an outer maximum height B of 3.6 mm and 6.5 mm are more comfortable than the nail tips with an outer maximum height B of 1.49 mm and 7.67 mm; in other embodiments, the nail tips with an outer maximum height B of 3.6 mm to 6.5 mm are more comfortable after being pasted on the surface of human nails.

[0033] In addition, the difference between the outer height B and the inner height A (i.e., the highest point 111 of the back side 11 of the nail plate body 1) (the outer height B is always higher than the inner height A) also affects the comfort of the nail plate. In order to test the comfort difference caused by different differences between the outer height B and the inner height A, the following Table 3 is obtained through experiments:

[0034]

[0035] 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 a nail piece with a corresponding value. Except for the different values ​​of the inner maximum height A of the nail piece body 1 and the different values ​​of the outer maximum height B of the nail piece body 1 (that is, the difference between the outer maximum height B and the inner maximum height A is different), the other parameters of the tried-on nail pieces are the same: the distance C (see below for the specific meaning) between the outer maximum height B of the nail piece body 1 and the rear end point 13 of the nail piece body 1 in the front-to-back direction is 10 mm; the total length D of the nail piece body 1 in the front-to-back direction is 34 mm.

[0036] 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 height A of 2.6mm, the nail piece body 1 outer height B of 3.6mm, and the difference between the outer height B and the inner height A of 1.0mm. 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 height A of 5.0mm, the nail piece body 1 outer height B of 6.1mm, and the difference between the outer height B and the inner height A of 1.1mm. 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 to high A of 3.5mm, the nail piece body 1 outer to high B of 4.8mm, and the difference between the outer to high B and the inner to high A of 1.3mm. The comfort scores of these two groups were high, with an average score of 92.5 points; the two groups of experimental groups 7 and 8 were the same nail pieces, corresponding to the nail piece body 1 inner to high A of 4.5mm, the nail piece body 1 outer to high B of 5.9mm, and the difference between the outer to high B and the inner to high A of 1.3mm. The difference between the inner height A and the inner height B is 1.4mm. The comfort scores of these two groups are relatively high, with an average score of 93.5 points. The experimental groups 9 and 10 are the same nail pieces, corresponding to the nail piece body 1 inner height A of 2.1mm, the nail piece body 1 outer height B of 3.6mm, and the difference between the outer height B and the inner height A of 1.5mm. The comfort scores of these two groups are relatively high, with an average score of 92.5 points. The control groups 11 and 12 are the same nail pieces, corresponding to the nail piece body 1 inner height A of 5.0mm. m, nail piece body 1 outer height B is 5.5mm, and the difference between outer height B and inner height A is 0.5mm. The comfort scores of these two groups are lower than that of the experimental group, with an average score of only 87.5 points; the control groups 13 and 14 are the same nail pieces, corresponding to the nail piece body 1 inner height A is 4.5mm, the nail piece body 1 outer height B is 6.5mm, and the difference between outer height B and inner height A is 2.0mm. The comfort scores of these two groups are also lower than that of the experimental group, with an average score of only 85.5 points.

[0037] In summary, for a nail art sheet with an inner height A of 2.1mm to 5.0mm and an outer height B of 3.6mm to 6.5mm, it is preferred that the difference between the outer height B and the inner height A (i.e., the value of the outer height B being higher than the inner height A) is 1.0mm to 1.5mm. Such a nail art sheet has better comfort.

[0038] To test the outermost point B of the nail plate body 1 (i.e. the highest point 121 of the front face 12 of the nail plate body 1) and the rear end point 13 of the nail plate body 1 (see Figure 3 ) The comfort difference caused by different values ​​of the distance C in the front and rear direction is obtained from the experiment in Table 4:

[0039]

[0040]

[0041] 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 of corresponding values. Except for the different values ​​of the distance C between the outer maximum height B of the nail tip body 1 and the rear end point 13 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 maximum height A of the nail tip body 1 is 5.0mm; the outer maximum height B of the nail tip body 1 is 6.5mm; the total length D of the nail tip body 1 in the front-to-back direction is 34mm.

[0042] From Table 4 above, we can see that the five groups of experimental groups 1 to 5 are the same nail pieces, corresponding to the nail piece body 1, the distance C between the outer height B and the rear end point 13 of the nail piece body 1 in the front-to-back direction is 10mm, and the comfort scores of these five groups are relatively high, with an average score of 93 points; the five groups of experimental groups 6 to 10 are the same nail pieces, corresponding to the nail piece body 1, the distance C between the outer height B and the rear end point 13 of the nail piece body 1 in the front-to-back direction is 7.2mm, and the comfort scores of these five groups are also relatively high, with an average score of 92.2 points; the control group 1 Groups 1 and 12 are the same nail pieces, corresponding to the beautiful nail pieces in which the distance C between the outer highest point B of the nail piece body 1 and the rear end point 13 of the nail piece body 1 in the front-to-back direction is 11.7 mm. The comfort scores of these two groups are lower than that of the experimental group, with an average score of only 82.5 points; the control groups 13 and 14 are the same nail pieces, corresponding to the beautiful nail pieces in which the distance C between the outer highest point B of the nail piece body 1 and the rear end point 13 of the nail piece body 1 in the front-to-back direction is 6.34 mm. The comfort scores of these two groups are also lower than that of the experimental group, with an average score of only 81 points. In summary, in this embodiment, the distance C between the outer maximum height B of the nail piece body 1 and the rear end point 13 of the nail piece body 1 in the front-to-back direction is 7.2mm and 10mm, which is more comfortable than the nail piece with a distance C of 6.34mm and 11.7mm. In other embodiments, the distance C between the outer maximum height B of the nail piece body 1 and the rear end point 13 of the nail piece body 1 in the front-to-back direction is 7.2mm~10mm, which has better comfort after being pasted to the surface of human nails.

[0043] The total length D of the test nail plate body 1 in the front-to-back direction (see Figure 3 ) The difference in comfort brought by different values, the experiment results in the following Table 5:

[0044]

[0045]

[0046] 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 of corresponding values. Except for the total length D 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 nail tip body 1 is 5.0 mm; the outer height B of the nail tip body 1 is 6.5 mm; the distance C between the outer height B of the nail tip body 1 and the rear end point 13 of the nail tip body 1 in the front-to-back direction is 10 mm.

[0047] From Table 5 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 D 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 D 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 D 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 D 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 D of 12.5 mm and 34 mm in the front-to-back direction are more comfortable than those with a total length D of 10.2 mm and 37.68 mm. In other embodiments, the nail tips with a total length D of 12.5 mm to 34 mm are more comfortable after being pasted to the surface of human nails.

[0048] In this embodiment, all the nail pieces in the nail piece assembly are not completely the same in size, the ratio of the inner height A to the outer height B of all the nail pieces is the same, the ratio of the outer height B to the total length D of all the nail pieces is the same, and the ratio of the distance C in the front-to-back direction between the outer height B of all the nail pieces (i.e., the highest point 121 of the front face 12 of the nail piece body 1) and the rear end point 13 of the nail piece body 1 is the same as the total length D. In other embodiments, all the nail pieces in the nail piece assembly can be changed to have only the same ratio of the inner height A to the outer height B, or only the same ratio of the outer height B to the total length D, or only the same ratio of the distance C in the front-to-back direction between the outer height B (i.e., the highest point 121 of the front face 12 of the nail piece body 1) and the rear end point 13 of the nail piece body 1 and the total length D.

[0049] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
