[0037] 1-4. Manufacturing method of cosmetic applicator 10 The method for manufacturing the cosmetic applicator 10 will now be described. First, the first foam layer 20 and the second foam layer 30 are prepared. An adhesive melted by heating is applied to one surface of the second foam layer 30. The first foam layer 20 is laminated on one surface of the second foam layer 30, sandwiching the molten adhesive therebetween. The laminated first foam layer 20 and second foam layer 30 are compressed, and the adhesive is cured to bond the first foam layer 20 and the second foam layer 30 together. If the adhesive is a moisture-curing hot-melt adhesive, the curing proceeds, for example, due to natural cooling and moisture in the air, resulting in a strong bond between the first foam layer 20 and the second foam layer 30. The laminate (raw sheet) in which the first foam layer 20 and the second foam layer 30 are bonded together is processed into a predetermined shape by punching, polishing, etc., to manufacture the cosmetic applicator 10.

[0038] 1-5. Application examples of the cosmetic applicator 10 The cosmetic applicator 10 is, for example, a puff, a sponge, a tip, etc. The cosmetic used may be in any form, including powder, liquid, cream, etc. The cosmetic may be, for example, a makeup cosmetic such as liquid foundation.

[0039] 1-6. Effects of 10 cosmetic applicators With the cosmetic applicator 10, the cosmetic fills the recesses (cut cells) exposed on the application surface 21 and is transferred to the skin by deformation caused by pressing with a finger or the like, allowing an appropriate amount to be spread widely across the skin. With the cosmetic applicator 10, the cross-section of the closed-cell structure is exposed on the application surface 21, so the cosmetic is less likely to penetrate than with a cross-section of cells with an open-cell structure, making it easier to apply the cosmetic widely and evenly, resulting in a good makeup finish. Furthermore, because the cosmetic is less likely to penetrate into the cosmetic applicator 10, the amount of cosmetic consumed can be reduced. Furthermore, because the cosmetic is less likely to penetrate into the cosmetic applicator 10, it can be easily cleaned and used hygienically.

[0040] The first foam layer 20 has a closed-cell structure in which the cells are not connected, resulting in relatively small stretch and poor conformability to the skin. However, by backing up the first foam layer 20 with the second foam layer 30, which has a soft, stretchy, open-cell structure, the cosmetic applicator 10 can be made softer against the skin, improving conformability to the skin. [Example]

[0041] The present invention will be explained in more detail below with reference to examples.

[0042] 1. Prepare the cosmetic applicator Cosmetic applicators of Examples 1 and 2 and Comparative Examples 1 to 3 were prepared. The cosmetic applicators of Examples 1 and 2 are formed by laminating a first foam layer with a closed-cell structure and a second foam layer with an open-cell structure in this order. In the cosmetic applicators of Examples 1 and 2, the cross sections of the cells of the closed-cell structure are exposed on the application surface (the surface of the first foam layer opposite the second foam layer).

[0043] In the cosmetic applicator of Example 1, the material of the first foam layer was polyethylene (the polyethylene with the product name "P·E Light" and product number "AR-102E" in Table 1), and the material of the second foam layer was acrylonitrile butadiene rubber (NBR) (the acrylonitrile butadiene rubber with the product name "NBR" and product number "Natural Whip" in Table 1). The thickness of the first foam layer was 2 mm. The thickness of the second foam layer was 6 mm.

[0044] In the cosmetic applicator of Example 2, the material of the first foam layer was polypropylene (polypropylene with the product name "FOLEC" and product number "LZ-2000" in Table 1), and the material of the second foam layer was acrylonitrile butadiene rubber (NBR) (acrylonitrile butadiene rubber with the product name "NBR" and product number "Natural Whip" in Table 1). The thickness of the first foam layer was 0.9 mm. The thickness of the second foam layer was 7 mm.

[0045] In the cosmetic applicators of Examples 1 and 2, the adhesive used to bond the first foam layer and the second foam layer was a urethane prepolymer manufactured by Resonac Co., Ltd., product name "Hibon" and product number "YR450-1."

[0046] The cosmetic applicator of Comparative Example 1 was formed by laminating a third foam layer with an open-cell structure and a fourth foam layer with an open-cell structure in this order. In the cosmetic applicator of Comparative Example 1, the cross sections of the cells of the open-cell structure were exposed on the application surface (the surface of the third foam layer opposite the fourth foam layer). The third foam layer was made of polyurethane, and the fourth foam layer was made of acrylonitrile butadiene rubber (NBR). The thickness of the third foam layer was 2 mm. The thickness of the fourth foam layer was 6 mm.

[0047] The cosmetic applicator of Comparative Example 2 was composed of a foam layer with an open-cell structure. The cross sections of the cells of the open-cell structure were exposed on the application surface of this foam layer. The material of this foam layer was acrylonitrile butadiene rubber (NBR) (product name "NBR" in Table 1, acrylonitrile butadiene rubber product number "Natural Whip"). The thickness of the foam layer was 8 mm.

[0048] The cosmetic applicator of Comparative Example 3 was formed by laminating, in this order, a fifth foam layer with an open-cell structure and a sixth foam layer with an open-cell structure. In the cosmetic applicator of Comparative Example 3, the cross sections of the cells of the open-cell structure were exposed on the application surface (the surface of the fifth foam layer opposite the sixth foam layer). The material of the fifth foam layer was polyethylene (polyethylene with the product name "MAPS" and product number "ST15-50" in Table 1), and the material of the sixth foam layer was acrylonitrile butadiene rubber (NBR) (acrylonitrile butadiene rubber with the product name "NBR" and product number "Natural Whip" in Table 1). The thickness of the fifth foam layer was 2 mm. The thickness of the sixth foam layer was 6 mm.

[0049] Table 1 shows the physical properties of the constituent materials of the cosmetic applicators of Examples 1 and 2 and Comparative Examples 1-3.

[0050] [Table 1]

[0051] 2. Cell Diameter Measurement The average cell diameter was measured for each of the polyethylene (product name "PE Light," product number "AR-102E"), polypropylene (product name "FOLEC," product number "LZ-2000"), and acrylonitrile butadiene rubber (product name "NBR," product number "Natural Whip") foams listed in Table 1. The cross section of each foam was observed at 50x magnification using a microscope (model "Digital Microscope VHX-2000"), and the diameter of 10 cells extracted from a 2 mm x 2 mm area was measured. The average cell diameter was calculated as the average of the diameters of the 10 cells. Figure 2 shows a microscopic image of the cross section of a polyethylene (product name "PE Light," product number "AR-102E") foam. Figure 3 shows the results of measuring the diameter of the 10 cells from Figure 2. Figure 4 shows a microscopic image of the cross section of a polypropylene (product name "FOLEC," product number "LZ-2000") foam. Figure 5 shows the results of measuring the diameters of 10 cells from Figure 4. Figure 6 is a microscope image of a cross section of a foam of acrylonitrile butadiene rubber (product name "NBR", product number "Natural Whip"), and Figure 7 shows the results of measuring the diameters of 10 cells from Figure 6.

[0052] The average cell diameter of the polyethylene (product name "PE Light", product number "AR-102E") foam was 260 μm. The average cell diameter of the polypropylene (product name "FOLEC", product number "LZ-2000") foam was 210 μm. The average cell diameter of the acrylonitrile butadiene rubber (product name "NBR", product number "Natural Whip") foam was 270 μm.

[0053] 3. Transfer Test Approximately 1 g of liquid foundation (product name "Maquillage Dramatic Jelly Liquid", product number "Ochre 20") was applied dropwise to the application surface of the cosmetic applicator of Examples 1 and 2 and Comparative Examples 1-3. The application surface of the cosmetic applicator was then compressed to 75% and released five times at a speed of 600 mm / min onto a test paper (polyurethane synthetic leather) representing skin, thereby transferring the cosmetic to the test paper. The transfer was performed at five different positions on the test paper without applying any additional cosmetic.

[0054] Figure 5 shows the transfer results using the cosmetic applicators of Examples 1 and 2 and Comparative Examples 1 to 3. The upper part of Figure 5 shows a photograph of each cosmetic applicator with the cosmetic applied. Figure 5 shows the state of the test paper after transfer to five locations in order from the bottom of the page for each Example and Comparative Example.

[0055] 4. Evaluation As shown in Figure 5, in Examples 1 and 2, the cosmetic was applied widely and uniformly in all five transfer locations. On the other hand, in Comparative Example 1-3, the application area of ​​the cosmetic was significantly smaller in all five transfer locations than in Examples 1 and 2. This result is thought to be because, in the cosmetic applicators of Examples 1 and 2, the cross sections of the cells with a closed cell structure are exposed on the application surface, making it difficult for the cosmetic to penetrate and easier to apply widely and uniformly compared to Comparative Example 1-3, in which the cross sections of the cells with an open cell structure are exposed on the application surface.

[0056] A test similar to the above transfer test was also conducted on a cosmetic applicator using only the polypropylene (product name "FOLEC", product number "OPN") in Table 1 as the foam layer. The results were similar to those of Comparative Examples 1-3, revealing that the cosmetic was easily absorbed and difficult to apply evenly over a wide area.

[0057] 5, in Example 2, the change in the amount of cosmetic applied was smaller among the five transfer locations than in Example 1. Furthermore, the cosmetic was more easily absorbed into Example 2 than in Example 1. This suggests that in Example 2, the cosmetic was more easily applied widely and uniformly even when the number of transfers was increased due to the appropriate amount of cosmetic absorbed.

[0058] 5. Effects of the Example According to the cosmetic applicators of the above examples, the cross sections of the cells with a closed cell structure are exposed on the application surface, so the cosmetic is less likely to penetrate than a cross section of cells with an open cell structure, and can be applied widely and evenly.

[0059] In the cosmetic applicator of the example, the first foam layer has a closed-cell structure, and the cells are not connected, so it has relatively small elongation and poor conformability to the skin. However, by backing up the first foam layer with a soft, elongated second foam layer with an open-cell structure, the cosmetic applicator feels softer on the skin and its conformability to the skin is improved.

[0060] The present disclosure is not limited to the above-described embodiments, and various modifications and variations are possible. [Explanation of symbols]
