Abstract
Description
Technical Field
[0001] This utility model relates to the field of nail art tips, specifically to a nail art tip with high comfort and a nail art tip assembly having the nail art tip. Background Technology
[0002] Existing nail extensions are typically designed to mimic the shape of a human nail (standard nail shape). Specifically: the back of the nail extension is designed to mimic the shape of a human nail, which has the advantage of a closer fit after application, minimizing discomfort and providing a more comfortable experience. The front of the nail extension is also designed to mimic the shape of a human nail, resulting in a more natural and realistic appearance. To apply the nail extension, a gel is first applied to the back of the extension, which is then adhered to the user's nail. The gel is then cured using UV light or similar methods. Because nail extensions require a gel coating between the back and the nail surface, extra space must be left for the gel to fit. This means they cannot perfectly mimic the shape of the user's nail. Furthermore, since everyone's nail shape is slightly different from the standard nail shape, even if the back of the nail extension is designed to mimic the standard nail shape, it may not perfectly match the user's nail surface. Therefore, users may still experience discomfort after the nail extensions are applied. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a nail tip with high comfort and a nail tip assembly having the nail tip. Even when the back of the nail tip cannot completely imitate the surface of the human nail, it can still make the user feel more comfortable after being pasted onto the surface of the human nail.
[0004] To solve the above problems, this utility model provides a nail tip with higher comfort, including a nail tip body that can be placed flat on a horizontal plane. The back of the nail tip body is arched upwards, and at least part of the edge surface of the nail tip body is downwards as the bottom surface. In the bottom surface, the highest point of the back bottom surface is suspended above the horizontal plane where it is placed, and its height is 1.7mm to 4.6mm.
[0005] Furthermore, the outer height of the plate body is 3.6mm to 6.5mm.
[0006] Furthermore, the distance between the outermost highest point of the armor plate and the rearmost point of the armor plate in the front-rear direction is 7.2mm to 10mm.
[0007] Furthermore, the total length of the armor plate body in the front-to-back direction is 12.5mm to 34mm.
[0008] Furthermore, the outer height of the front edge of the armor plate body is 0.5mm to 6.2mm.
[0009] Furthermore, the outermost width of the plate body is 6.5mm to 15mm.
[0010] Specifically, the left, right, and rear edge surfaces of the armor plate body face downwards as the bottom surface.
[0011] This utility model also provides a nail tip assembly, comprising multiple nail tips of different sizes, wherein at least one nail tip is a nail art tip as described above.
[0012] Furthermore, the nail art pieces consist of at least two pieces, which are not exactly the same size, and the ratio of the outer edge height to the outer top height of all nail art pieces is the same.
[0013] Furthermore, the nail plate has five pieces, which are respectively used to be pasted onto the nail surfaces of the five fingers on the same palm.
[0014] Beneficial effects: When the highest point of the back surface of the nail tip of this utility model is 1.7mm to 4.6mm, even if the back of the nail tip cannot completely imitate the shape of the human nail surface, experimental verification shows that it can still make the user feel more comfortable after being pasted onto the human nail surface.

Detailed Implementation
[0022] The present invention will be further described in detail below with reference to specific embodiments.
[0023] The nail tip assembly includes five nail tips, each a slightly different size, designed to be applied to the nail surfaces of the five fingers on the same hand. For example, see... Figure 1 It includes a plate body 1, which is symmetrical from left to right and arched with its back facing upwards; the left, right, and rear edge surfaces 10 of the plate body 1 face downwards as the bottom surface, and the plate body 1 can be opened up by relying on the left and right bottom surfaces (i.e., the left and right edge surfaces 10) as... Figure 2 As shown, the nail plate is placed flat on a horizontal plane (i.e., the dotted line in the figure). The bottom surface 11 will be suspended above the horizontal plane where it is placed. The back of the nail plate body 1 can be pasted onto the surface of the human nail after applying gel. Because the back of the nail plate body 1 needs to reserve space 12 for gel application, it cannot completely conform to the shape of the user's nail surface. After pasting onto the surface of the human nail, it may easily cause discomfort to the user.
[0024] The inventors discovered that when the back of the nail tip body 1 cannot perfectly mimic the surface of a human nail, several factors affect user comfort after the nail tip is applied to the nail surface. The shape of the back of the nail tip and its own center of gravity have a significant impact on comfort. These two factors are further influenced by several sub-factors, such as the total length, width, height, and edge height of the nail tip body 1. Among these, the outer height A of the rear edge of the nail tip body 1 (see...) Figure 2 The height of the rear edge (A, i.e., the height of the highest point 111 on the rear bottom surface 11 of the armor plate body 1) has a significant impact. To test the comfort differences caused by different values of the rear edge height A of the armor plate body 1, the following table shows the experimental results:
[0025] Serial number Specific value of outer height A of back edge of body 1 of A sheet Comfort score Experimental group 1 4.6 mm 91 Experimental group 2 4.6 mm 92 Experimental group 3 4.6 mm 94 Experimental group 4 4.6 mm 92 Experimental group 5 4.6 mm 92 Experimental group 6 1.7 mm 93 Experimental group 7 1.7 mm 92 Experimental group 8 1.7 mm 91 Experimental group 9 1.7 mm 91 Experimental group 10 1.7 mm 92 Control group 11 5.74 mm 74 Control group 12 5.74 mm 75 Control group 13 1.49 mm 78 Control group 14 1.49 mm 75
[0026] Note: In the 14 sets of data given in Table 1 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 different values of the outer height A of the back edge of the nail art piece 1, the other parameters of the nail art pieces tried on are the same: the outer height B of the nail art piece 1 (see below for specific meaning) is 6.5mm; the distance C between the outer height B and the back end point 14 of the nail art piece 1 in the front-back direction is 10mm; the total length D of the nail art piece 1 in the front-back direction is 34mm; the outer height E of the front edge of the nail art piece 1 (see below for specific meaning) is 6.2mm; and the outer width F of the nail art piece 1 is 15mm.
[0027] As shown in Table 1 above: Experimental groups 1-5 used the same nail tips, corresponding to nail art tips with an outer back edge height (A) of 4.6mm. These five groups all had high comfort scores, with an average score of 92.2. Experimental groups 6-10 also used the same nail tips, corresponding to nail art tips with an outer back edge height (A) of 1.7mm. These five groups also had high comfort scores, with an average score of 91.8. Control groups 11 and 12 used the same nail tips, corresponding to nail art tips with an outer back edge height (A) of 5.74mm. These two groups had lower comfort scores compared to the experimental groups, with an average score of only 74.5. Control groups 13 and 14 used the same nail tips, corresponding to nail art tips with an outer back edge height (A) of 1.49mm. These two groups also had lower comfort scores compared to the experimental groups, with an average score of only 76.5. In summary, in this embodiment, the nail art pieces with an outer back edge height A of 1.7mm and 4.6mm are more comfortable than those with an outer back edge height A of 5.74mm and 1.49mm; in other embodiments, nail art pieces with an outer back edge height A of 1.7mm to 4.6mm are generally more comfortable after being applied to the surface of the nail.
[0028] The comfort of nail extensions is greatly affected not only by the outer height A of the nail extension body 1, but also by the outermost height B of the nail extension body 1, the outermost height B of the nail extension body 1, and the rear end point 14 of the nail extension body 1 (see...). Figure 4 The distance C in the front-to-back direction, the total length D of the plate body 1 in the front-to-back direction, the outer height E of the leading edge of the plate body 1, and the outer width F of the plate body 1 are all affected by multiple parameters. These parameters have a slightly smaller impact than the outer height A of the trailing edge. These parameters will be tested one by one in the following text.
[0029] See Figure 3 The outermost height B of the nail tip body 1 is the height of the highest point 13 on the front of the nail tip body 1, and the highest point 13 is located on the center line of the nail tip body 1. All nail tips in the nail tip assembly have the same ratio of outermost height A to outermost height B along their rear edge. To test the comfort differences caused by different values of the outermost height B of the nail tip body 1, the experiment yielded the following Table 2:
[0030] Serial number Specific value of outer height B of body 1 of A sheet Comfort score Experimental group 1 6.5 mm 92 Experimental group 2 6.5 mm 93 Experimental group 3 6.5 mm 91 Experimental group 4 6.5 mm 92 Experimental group 5 6.5 mm 93 Experimental group 6 3.6 mm 93 Experimental group 7 3.6 mm 91 Experimental group 8 3.6 mm 91 Experimental group 9 3.6 mm 92 Experimental group 10 3.6 mm 93 Control group 11 7.67 mm 83 Control group 12 7.67 mm 81 Control group 13 2.38 mm 82 Control group 14 2.38 mm 82
[0031] Note: In the 14 sets of data given in Table 2 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 height B of the nail art piece body 1, the other parameters of the nail art pieces tried on are the same: the outer edge height A of the nail art piece body 1 is 4.6mm; the distance C between the outer edge height B and the rear end point 14 of the nail art piece body 1 in the front-back direction is 10mm; the total length D of the nail art piece body 1 in the front-back direction is 34mm; the outer edge height E of the nail art piece body 1 (see below for specific meaning) is 6.2mm; and the outer width F of the nail art piece body 1 is 15mm.
[0032] As shown in Table 2 above: Experimental groups 1-5 used the same nail tips, corresponding to nail art tips with an outer height B of 6.5mm. These five groups all had high comfort scores, with an average score of 92.2. Experimental groups 6-10 also used the same nail tips, corresponding to nail art tips with an outer height B of 3.6mm. These five groups also had high comfort scores, with an average score of 92. Control groups 11 and 12 used the same nail tips, corresponding to nail art tips with an outer height B of 7.67mm. These two groups had lower comfort scores compared to the experimental groups, with an average score of only 82. Control groups 13 and 14 used the same nail tips, corresponding to nail art tips with an outer height B of 2.38mm. These two groups also had lower comfort scores compared to the experimental groups, with an average score of only 82. In summary, in this embodiment, nail art pieces with an outer height B of 3.6mm and 6.5mm offer better comfort than those with an outer height B of 1.49mm and 7.67mm. In other embodiments, nail art pieces with an outer height B between 3.6mm and 6.5mm provide good comfort after being applied to the nail surface.
[0033] To test the outermost high point B of the armor plate body 1 (i.e., the highest point 13 on the front of the armor plate body 1) and the rear end point 14 of the armor plate body 1 (see... Figure 4 The experiment yielded the following Table 3, which shows the differences in comfort caused by different values of distance C in the front-to-back direction:
[0034]
[0035]
[0036] Note: In the 14 sets of data given in Table 3 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 value of the outer height B of the nail art piece body 1 and the distance C of the rear end point 14 of the nail art piece body 1 in the front-back direction, the other parameters of the nail art pieces tried on are the same: the outer height A of the rear edge of the nail art piece body 1 is 4.6mm; the outer height B of the nail art piece body 1 is 6.5mm; the total length D of the nail art piece body 1 in the front-back direction is 34mm; the outer height E of the front edge of the nail art piece body 1 (see below for specific meaning) is 6.2mm; and the outer width F of the nail art piece body 1 is 15mm.
[0037] As shown in Table 3 above: Experimental groups 1-5 used the same nail tips, with a distance C of 10mm between the outermost height B of the nail tip 1 and the rearmost point 14 of the nail tip 1 in the front-back direction. All five groups had high comfort scores, with an average score of 93. Experimental groups 6-10 also used the same nail tips, with a distance C of 7.2mm between the outermost height B of the nail tip 1 and the rearmost point 14 of the nail tip 1 in the front-back direction. All five groups also had high comfort scores, with an average score of 92.2. Control group 1... Groups 1 and 12 consist of the same nail tip, with the distance C between the outermost height B of the nail tip body 1 and the rearmost point 14 of the nail tip body 1 in the front-back direction being 11.7 mm. The comfort scores of these two groups were lower than those of the experimental group, with an average score of only 82.5. The control groups 13 and 14 consist of the same nail tip, with the distance C between the outermost height B of the nail tip body 1 and the rearmost point 14 of the nail tip body 1 in the front-back direction being 6.34 mm. The comfort scores of these two groups were also lower than those of the experimental group, with an average score of only 81. In summary, in this embodiment, the nail art pieces with a distance C between the outermost height B of the nail body 1 and the rear end point 14 of the nail body 1 in the front-back direction of 7.2mm and 10mm provide better comfort than those with a distance C of 6.34mm and 11.7mm. In other embodiments, nail art pieces with a distance C between the outermost height B of the nail body 1 and the rear end point 14 of the nail body 1 in the front-back direction of 7.2mm to 10mm provide good comfort after being pasted onto the surface of the nail.
[0038] To test the total length D of the armor plate body 1 in the front-to-back direction (see...) Figure 4 The differences in comfort levels resulting from different values are shown in Table 4 below:
[0039]
[0040]
[0041] Note: In the 14 sets of data given in Table 4 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.

[0042] As shown in Table 4 above: Experimental groups 1-5 used the same nail tips, corresponding to nail tips with a total length D of 34mm in the front-to-back direction. These five groups had high comfort scores, with an average score of 92.8. Experimental groups 6-10 used the same nail tips, corresponding to nail tips with a total length D of 12.5mm in the front-to-back direction. These five groups also had high comfort scores, with an average score of 92.2. Control groups 11 and 12 used the same nail tips, corresponding to nail tips with a total length D of 37.68mm in the front-to-back direction. 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 a total length D of 10.2mm in the front-to-back direction. 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 a total length D of 12.5mm and 34mm in the front-to-back direction are more comfortable than those with a total length D of 10.2mm and 37.68mm. In other embodiments, nail art pieces with a total length D of 12.5mm to 34mm are generally more comfortable after being pasted onto the surface of the nail.
[0043] To test the outer height E of the leading edge of plate 1 (see...) Figure 2 The difference in comfort caused by different values of the frontal outer height E (i.e., the height of the highest point of the frontal surface 15 of the armor plate body 1) is shown in Table 5 below:
[0044]
[0045]
[0046] 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 different values of the outer edge height E of the nail art piece body 1, the other parameters of the nail art pieces tried on are the same: the outer edge height A of the nail art piece body 1 is 4.6mm; the outer height B of the nail art piece body 1 is 6.5mm; the distance C between the outer height B and the rear end point 14 of the nail art piece body 1 in the front-back direction is 10mm; the total length D of the nail art piece body 1 in the front-back direction is 34mm; and the outer width F of the nail art piece body 1 is 15mm.
[0047] As shown in Table 5 above: Experimental groups 1-5 used the same nail tips, corresponding to nail tips with an outer edge height E 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 E 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 E 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 E 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 E of 0.5mm and 6.2mm are more comfortable than those with an outer edge height E of 0.28mm and 7.38mm. In other embodiments, nail art pieces with an outer edge height E of 0.5mm to 6.2mm are generally more comfortable after being applied to the surface of the nail.

[0052] As shown in Table 6 above: Experimental groups 1-5, which use the same nail tips (corresponding to nail tips with a width F of 15mm from the outer edge of the nail tip body), all had high comfort scores, with an average score of 93.2. Experimental groups 6-10, which use the same nail tips (corresponding to nail tips with a width F of 6.5mm from the outer edge of the nail tip body), also had high comfort scores, with an average score of 92. Control groups 11 and 12, which use the same nail tips (corresponding to nail tips with a width F of 17.49mm from the outer edge of the nail tip body), had lower comfort scores compared to the experimental groups, with an average score of only 79.5. Control groups 13 and 14, which use the same nail tips (corresponding to nail tips with a width F of 6.03mm from the outer edge of the nail tip body), 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 width F of 6.5mm and 15mm are more comfortable than those with an outer width F of 6.03mm and 17.49mm. In other embodiments, nail art pieces with an outer width F of 6.5mm to 15mm are generally more comfortable after being attached to the surface of the nail.
