Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to cosmetic application materials. More specifically, the present invention is applicable to paste make-up cosmetics and, in some cases, liquid make-up cosmetics. Concerning suitable cosmetic application materials.

〔Technical field〕

BACKGROUND ART Block-shaped cosmetic applicators made of various foams such as foamed urethane and foamed rubber have been used as cosmetic applicators for pasty makeup cosmetics.

Incidentally, in recent years, there has been a trend toward lower viscosity of paste-like makeup cosmetics for the purpose of improving usability, such as increasing the spreadability and adhesion of cosmetics during application. In other words, the state of cosmetics has changed from paste-like to liquid-like.

When applying such low-viscosity, paste-like makeup cosmetics that are close to liquid cosmetics using a conventional foam block-shaped cosmetic applicator, the cosmetics penetrate into the inside of the foam. There is a problem that there is a lot of wasteful consumption of cosmetics during application.

In addition, as mentioned above, when using a low-viscosity paste make-up cosmetic, the cosmetic easily migrates into the inside of the foam, making it impossible to apply thickly, which may increase the spreadability and adhesion of the cosmetic when applied. The purpose of using a low-viscosity paste-like makeup cosmetic composition, which is to improve the usability of cosmetics, cannot be achieved, and there is also the problem of uneven application.

In order to solve the above-mentioned problems of ineffective consumption of cosmetics, decreased usability of cosmetics, and spots, the present inventor conducted the following study.

First, as disclosed in Japanese Utility Model Application Publication No. 53-146483, a preferably impermeable synthetic resin layer is formed on the surface of a porous material such as a foam or nonwoven fabric, and the synthetic resin layer is An attempt was made to plant short fibers (pile) on the surface via an adhesive layer. This is aimed at preventing the cosmetic from penetrating into the porous material with the synthetic resin layer, while improving the absorption of the cosmetic through the planted pile. However, as a result of testing, although the synthetic resin layer was able to prevent internal penetration of cosmetics, the pile planting effect was extremely low.

In other words, when applying paste cosmetics, the piles that have been planted tend to fall sideways, making it impossible to apply thickly, and in addition, the piles that fall sideways cause the application to occur in streaks and patches. presented.

Furthermore, as another method, the present inventor fabricated a cosmetic applicator by forming irregularities on the surface of a rubber cover and filling the inside of the cover with foam, and conducted an application test. According to this cosmetic applicator, application spots did not occur. However, during application, the foam core material could not fully follow the elongation of the rubber cover, and the foam stuffed inside the cover moved, making it unable to maintain its firmness as a cosmetic applicator. It was difficult to apply, did not feel good when used as a cosmetic applicator, and was not practical.

Furthermore, an attempt was made to apply an adhesive to the porous material and to bond and fix the rubber cover and the porous material using the adhesive. However, because the adhesive penetrates into the pores of the porous material and solidifies, the resulting cosmetic applicator has low flexibility and loses its elastic effect, resulting in a poor usability and impractical use as a cosmetic applicator. was low.

[Purpose of invention]

Based on the conventionally known cosmetic applicators and test results as described above, the present invention aims to provide a cosmetic applicator that can fully utilize the characteristics of paste makeup cosmetics. More specifically, the present invention does not allow internal penetration of cosmetics when applied, has good absorption of cosmetics, can be applied thickly, does not cause uneven application, has excellent elasticity, and has a comfortable feel when used. The purpose of the present invention is to provide a cosmetic application material with good quality.

[Structure of the idea]

The present invention achieves the above object by comprising a porous material, an inner film layer formed on the outer surface of the porous material, and an outer film layer formed on the outer surface of the inner film layer, the outer film layer being This is achieved by using a cosmetic applicator having fine irregularities on its outer surface. It is preferred that the inner coating layer be an impermeable coating to more effectively prevent the paste cosmetic from penetrating into the porous material. Alternatively, the inner film layer and the outer film layer may be bonded together using an adhesive layer to effectively prevent the paste cosmetic from penetrating into the porous material. Further, from the viewpoint of ease of manufacture as a cosmetic applicator and usability as a cosmetic applicator, it is preferable that the irregularities formed on the outer film layer have a satin-like, fingerprint-like, or crest-like shape.

Note that if the film layer is one layer, it is difficult to bond the film layer and the porous material without using an adhesive.On the other hand, it is difficult to bond the film layer and the porous material using an adhesive. In this case, the pores of the porous material become pores, resulting in a poor feeling of use. In addition, without using adhesive,
When attempting to bond a film layer and a porous material, heat bonding is required, but with the heat bonding method, all the unevenness formed on the coated surface changes to a flat surface due to heating, making it difficult to use as a cosmetic applicator. It will not be able to fulfill its function. Therefore, one coating layer formed on the surface of the porous material is insufficient, and in the present invention, it is necessary to form two coating layers, an inner layer and an outer layer.

[Explanation of Examples]

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing embodiments of the present invention.

1 to 3 are enlarged sectional views of different embodiments of the cosmetic applicator of the present invention, respectively.

In FIGS. 1 to 3, reference numeral 1 indicates a porous material. The porous material 1 of the present invention can be made of various foams such as polyurethane foam, polyvinyl chloride foam, and rubber foam, nonwoven fabric, or woven fabric.
An inner coating layer 2 is formed on the surface of the porous material 1.

The material of the inner film layer 2 is acrylic resin, polyurethane resin, polyester resin, polyolefin resin, polyamide resin, or the like. Note that the inner film 2 is preferably impermeable. Further, in order to bond the porous material 1 without sealing the pores, the porous material 1 and the inner coating layer 2 are bonded by a heat transfer method.

The heat transfer method uses a release mount (not shown) made of a sheet impregnated with silicone or wax.
On top, the above-mentioned resin for the inner coating layer 2 is formed into a film by printing or coating, and the surface of the release mount is coated with the resin film surface of the release mount in close contact with the surface of the porous material 1. This method involves heating and pressurizing the mold, and then peeling off the release mount.

By using the heat transfer method in this way, the resin film formed on the release mount is adhered to the apex 5 of the skeleton on the surface of the porous material 1, and an inner film layer is formed on the surface of the porous material 1. 2 is formed.

Next, the outer coating layer 3 is bonded and formed on the surface of the inner coating layer 2 formed as described above. Fine irregularities are formed on the outer surface of the outer film layer 3 in order to improve the absorption of the cosmetic to be applied and to enable the cosmetic to be applied satisfactorily.

The material of the outer film layer 3 is a film of flexible synthetic resin such as polyurethane resin, polyester resin, polyamide resin, polyolefin resin, silicone resin, or a film of acrylic rubber, silicone rubber, styrene-butadiene rubber, etc. Further, the outer film layer 3 may be formed of a foamed film made of the above-mentioned material.

To join the inner film layer 2 and the outer film layer 3, an organic solvent is applied to the surface of the outer film layer 3 opposite to the uneven surface, and a part of the surface is dissolved, and in this state,
The side opposite to the uneven surface of the melted outer film layer 3,
Place it on the inner membrane layer 2 and apply pressure to adhere it.

The irregularities formed on the outer surface of the outer film layer 3 can have various shapes. For example, as shown in Figure 1,
It may also be a satin-like uneven surface 4 in which a large number of fine circular unevenness such as the surface of a pear fruit is formed. Furthermore, as shown in FIG. 2, the surface 6 may have a fingerprint-like uneven surface 6 consisting of unevenness in a pattern similar to a fingerprint of a hand, that is, a pattern of rhytides, spirals, or a combination thereof. Furthermore, as shown in FIG. 3, a ridge-like uneven surface 7 can be formed in which many small mountain-like unevennesses are formed. Further, these uneven surfaces may be combined.

In order to form the satin-like uneven surface 4 shown in FIG. Pressure is applied to the layer 3 to form a satin-like uneven surface 4 on the surface of the outer film layer 3 in the same manner as embossing. Another method is to form a satin-like pattern on one side of a mold (not shown) for molding the outer film layer 3, and then use this mold to mold the outer film layer 3 to create a satin-like pattern. An uneven surface 4 can be formed.

Similarly, in order to form the fingerprint-like uneven surface 6 shown in FIG. (not shown) is heated and pressed against the outer film layer 3 to form a fingerprint-like uneven surface 6 on the surface of the outer film layer 3 in the same manner as embossing. Another method is to form a fingerprint-like pattern on one side of a mold (not shown) for molding the outer film layer 3, and use this mold to mold the outer film layer 3, thereby creating a fingerprint-like pattern. An uneven surface 6 can be formed.

Furthermore, in order to form the ridge-shaped uneven surface 7 shown in FIG. Then, in the same manner as embossing, a ridge-shaped uneven surface 7 is formed on the surface of the outer film layer 3. Another method is to form a crest-shaped pattern on one side of a mold (not shown) for molding the outer film layer 3, and then use this mold to mold the outer film layer 3. An uneven surface 7 can be formed.

The irregularities 4, 6, and 7 on the outer surface of the outer film layer 3 improve the absorption of cosmetics, and their size and height can be determined depending on the type of cosmetics, viscosity, etc. In order to have good coverage, thick coating, and no uneven coating, the depth of the uneven part should be 20~20~20cm.
Approximately 150μ is preferable. In addition, the uneven pattern is
Fingerprint patterns that resemble the fingers of a hand are most effective.

In order to use a thin film and form large (deep) irregularities to sufficiently absorb the cosmetic, it is preferable that the outer film layer 3 is also impermeable.

With the cosmetic applicator constructed as described above, the unevenness formed on the outer surface of the outer film layer 3 can be impregnated with a paste-like makeup cosmetic material with a relatively low viscosity, allowing thick application and avoiding uneven application. will not occur. In addition, the inner coating layer 2 is formed on the surface of the porous material 1, so that the adhesive does not penetrate or seal the pores of the porous material 1, and the elastic effect of the porous material 1 is not lost. The cosmetic applicator provides a good feeling of use. Furthermore, since the inner coating layer 2 is formed on the surface of the porous material 1, it is possible to prevent the cosmetic from penetrating into the inside of the porous material 1.

In the above embodiments, the inner coating layer 2 and the outer coating layer 3 were directly bonded, but as shown in FIG. A solvent-based, emulsion-based, or two-component curing adhesive is applied to both sides to form an adhesive layer 8.
The inner coating layer 2 and the outer coating layer 3 may be bonded together via the adhesive layer 8. In this way, the porous material 1, the inner film layer 2, and the outer film layer 3
There is no slippage, and the elasticity is maintained even when used as a cosmetic applicator. The adhesive layer 8 also has the effect of preventing the paste makeup cosmetic from penetrating into the porous material 1.

In addition, even in the embodiment shown in FIG. 4, the porous material 1, the inner film layer 2, the outer film layer 3, and the irregularities 4, 6, and 7 formed on the outer film layer 3 are as shown in FIGS. 1 to 3. The embodiment can be similar to the embodiment described with reference to .

The cosmetic applicator material of the present invention can be made into a cosmetic applicator by a well-known method such as punching.
