Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a cosmetic applicator in which two porous bodies having different pore diameters are laminated and integrated.

[Prior art]

As a cosmetic applicator for applying cosmetics such as white powder, blusher, and eye shadow to the skin or the like, a cosmetic applicator made of a porous body such as urethane foam having continuous pores is known. However, the raw cosmetic powder is extremely fine, and particularly the recent solid or emulsified cosmetics are finer than the pore diameter of 50 μm to 1 mm of the urethane foam constituting the applicator. Therefore, there is a drawback that the cosmetic material penetrates deep into the pores of the urethane foam and is hard to be applied to the skin or the like, and uneven coating is likely to occur. Further, the cosmetic material that has entered the pores is difficult to remove even after washing, and there is a problem that the coating material loses its elastic force and is not suitable for use because it remains as it is and is oxidized and solidified. This tendency is particularly remarkable in oily and emulsified cosmetics. Further, the conventional urethane foam constituting the applicator has appropriate elasticity and is comfortable to use, but there is a problem that the surface is rough and the feel during use, especially the feel during sliding, is unfavorable.

As a currently known applicator for solving such a problem, first of all, an applicator having a structure in which sheet bodies having different pore diameters are bonded to each other with an adhesive is known. There is.

As the second applicator, as shown in Japanese Utility Model Publication No. 57-38094, there is known one in which a fine urethane film layer having fine pores is formed on the surface of a skeleton body made of a porous body.

[Problems to be solved by the invention]

However, the two conventional applicators described above have the following problems.

First, in the first applicator, the bonding process for bonding the two sheet bodies is very troublesome. In addition, since the adhesive layer is provided, the flexibility is so poor that the user feels uncomfortable at the time of use. Further, there is a problem that it is easily peeled off from the adhesive surface after long-term use.

In addition, the second applicator is not intended to be used properly according to the type of cosmetics, but is intended to soften the skin irritation such as a tingling or tingling sensation. The material at the tip of the body is coated with a soft material to prevent the material constituting the skeleton from directly contacting the skin. Therefore, the coating layer is formed very thin, the diameter of the pores opening on the surface of the skeleton due to the formation of the coating layer is slightly reduced, but it remains open.
It is not possible to use it properly according to the type of cosmetics.

The present invention has been made in view of the above-mentioned problems of the prior art,
The purpose is to form a porous layer on one surface in which pores of uniform diameter different in size from the other surface are uniformly dispersed, depending on the type of cosmetics or according to the preference of the user. It is an object of the present invention to provide a cosmetic applicator which can be used properly and has excellent feeling of use and is resistant to structural and physical changes even when used for a long period of time.

[Means for solving problems]

Next, the present invention will be described with reference to FIGS. 1 and 2 showing an embodiment of the present invention.

The cosmetic applicator according to the present invention is a synthetic resin, which is a foamed molded product such as acrylonitrile butadiene rubber having continuous pores, in which skin layers 12 having very fine eyes and preventing permeation of cosmetics are formed on both front and back surfaces. On the skin layer 12 side of a flat plate-shaped skeleton body 10 obtained by slicing a porous body made into two, there are pores smaller in size than the pores formed in the skeleton body 10 that are foamed by mechanical foaming means. The synthetic resin porous coating layer 20 is formed by cross-linking, the coating layer 20 is wrapped around the outer peripheral edge of the skeleton body 10, and the entire region of the skeleton body 10 excluding one surface is covered with the coating layer 20. It was done like this.

[Action]

Coating layer 20 formed on one side of skeleton body 10
Has pores formed by a mechanical foaming means and has a pore size smaller than that of the skeleton body 10 and has a structure in which pores of a uniform size are uniformly dispersed. Therefore, there is little clogging and a very smooth skin feeling. Becomes

Further, the skeleton body 10 is obtained by slicing a synthetic resin porous body, which is a foamed molded body, into two, and the pores are uniform on the side opposite to the coating layer bonding surface of the skeleton body 10 (exposed surface of the skeleton body 10). Since it is formed by the cut surfaces dispersed in, the cosmetic can uniformly impregnate the surface of the skeleton body 10.

In addition, an extremely fine layer (skin layer) 12 is formed on the joint surface between the skeleton body 10 and the coating layer 20, and the skin layer 12 is formed from the skeleton body 10 of the cosmetic to the coating layer 20 or the coating layer. 20 to skeleton 1
Acts as a barrier to the zero transition.

Further, since the fine coating layer 20 covers the outer peripheral edge portion of the coarse skeleton body 10 and the outer peripheral edge portion of the disk-shaped applicator is formed by the fine mesh coating layer 20, the base of the nose or the eyebrows is formed. With a smooth touch, you can apply makeup evenly to narrow areas such as between your eyes.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 and 2 are sectional views of a puff which is a makeup applicator according to a first embodiment of the present invention.

In these drawings, reference numeral 10 is a disc-shaped porous skeleton body made of acrylonitrile-butadiene rubber (hereinafter referred to as NBR) having continuous pores, and has a diameter smaller than that of the skeleton body 10 on the surface of the skeleton body 10. The porous coating layer 20 made of polyurethane having pores is integrated by cross-linking to form a cosmetic puff.

The coating layer 20 is formed so as to extend to a position below the outer peripheral edge of the skeleton body 10 and cover most of the area of the skeleton body 10 excluding the bottom surface. The coating layer 20 is a polyurethane foam that is foamed by mechanical foaming means by stirring, has a structure in which pores having a smaller diameter than the skeleton body 10 and having a uniform diameter are uniformly dispersed, and is somewhat elastic from the skeleton body 10. Has been made smaller. Both of them are integrated by cross-linking, and the back surface of the skeleton body 10 having coarse and highly elastic is exposed and the eyes are fine, and the skeleton body 1 has elasticity.
The exposed surface of the coating layer 20 which is inferior to 0 can be selectively used according to the type of cosmetics or the preference of the user.

A smooth surface layer (hereinafter referred to as a skin layer) 1 formed at the interface with the air at the time of forming the foam body 1 in the plane area of the joint surface of the skeleton body 10 with the coating layer 20.
2 is formed, and on the other hand, the back surface of the skeleton body 10 and the R-shaped portion of the outer peripheral edge portion indicated by reference numeral 15 are the mesh layer 16 in which the inside of the skeleton body 10 is directly exposed. That is, the fine skin layer 12 is formed between the skeleton body 10 and the coating layer 20, and the cosmetic material that has entered the skeleton body 10 from the mesh layer 16 side of the puff is on the other side (coating layer 20). ) Is difficult to penetrate.

Further, the skin layer 2 having a fine texture and a very smooth feel in the flat area of the coating layer 20 forming the surface of the puff.
2 is formed, and the surface region (R-shaped portion of the outer peripheral edge of the puff) of the coating layer 20 excluding the skin layer 22 is formed by cutting the coating layer 20 at positions 23a and 23b. The inside of the coating layer 20 is a mesh layer 26 that is directly exposed. That is, most of the surface of the coating layer 20 is covered with the mesh layer 2
Since the skin layer 20 having a finer mesh than 6 is formed, a very fine makeup can be achieved with a smooth feeling of use.

The present embodiment has the following effects.

Since the surface roughness of the puff differs from that of the back surface, both sides of the puff can be used properly according to the type of cosmetics and the intention of the user. Particularly in liquid cosmetics, by using the coating layer 20, the cosmetics do not penetrate deeply into the puff, and the conventional problems such as uneven coating and waste of the cosmetics can be solved. Further, which surface is to be used can be selectively used according to the preference of the user, and the coating layer 20 has a smooth and smooth feeling, while the skeleton body 10 has a soft touch and a clean feeling. In particular, since the coating layer 20 is a porous body in which pores are formed by mechanical foaming, pores having a uniform diameter are uniformly dispersed, and a skin layer 22 is formed in the plane area of the surface. Therefore, there is a singular point that a very smooth feeling can be obtained.

Since the skin layer 12 is formed on the joint surface of the skeleton body 10 with the coating layer 20, it is difficult for cosmetics, particularly liquid cosmetics, to permeate to the opposite side, and there is no problem that the two cosmetics are mixed depending on their use. .

Since the fine coating layer 20 is formed also in the outer peripheral edge region of the puff, it is possible to apply a smooth touch evenly to a narrow portion such as the base of the nose or between the eyebrows and the eyes.

Since the skeleton body 10 and the coating layer 20 are cross-linked and bonded, there is no discomfort as in an integrated structure with an adhesive, and neither peeling occurs on the bonded surface during long-term use.

Next, a procedure for manufacturing the puff according to this embodiment will be described.

First, one manufacturing procedure of the skeleton body 10 will be described. Introduction N
The BR porous body sheet is punched into a predetermined circular shape to form a disc-shaped NBR porous skeleton body 50 as shown in FIG. Since the manufacturing procedure of the NBR sheet is not different from the conventional foamed sheet manufacturing procedure, its description is omitted.

The skin layer 12 is formed on the front and back surfaces of the skeleton body 50, and the skeleton body 50a having the skin layer 12 formed on the surface by slicing the skeleton body 50 into two at positions indicated by reference numeral X in FIG.
Two are formed. The outer peripheral edge portion of the skeleton body 50a is cut into an R shape as shown by the dashed line in FIG. 3, and the skeleton body 10 having the outer peripheral edge R portion 15 is formed as shown in FIG. To manufacture.

Next, the coating layer 2 is formed on the skin layer 12 side of the skeleton body 10.
A procedure for forming 0 will be described.

First, as shown in FIG. 4 (a), an emulsion A as a polyurethane raw material is put in a container 60, and then a cross-linking agent B is put and mixed uniformly. Further, the foam stabilizer C, the foaming agent (foaming agent) B, and the thickener E are lightly mixed and sequentially mixed. When the curing accelerator is used, the catalyst agent F is added last.

After the mixed solution is uniformly mixed, as shown in FIGS. 4 (b) and 4 (c), high speed stirring is performed by a stirrer 62 to mix air into the mixed solution and foam at a predetermined ratio (for example, 3 times). Let
After reaching the predetermined magnification, stirring is continued in the state where the stirring blade 64 is submerged below the surface of the foaming liquid for a shorter time. Then, the foaming liquid in which the air bubbles are uniformly dispersed is shown in FIG.
As shown in (a) or FIG. 5 (b), it is applied to the surface of the skeleton body 50a arranged at predetermined intervals. Reference numeral 20a indicates the applied foam liquid layer. Then, preheating is performed at a temperature of 80 to 120 ° C. for several minutes, and curing is performed at a temperature of 150 to 170 ° C. for several minutes. Then, the outer peripheral edge corner portions shown by reference numerals 23a and 23b in FIG. 2 are cut so as to have an R shape, and a puff having the shape shown in FIG. 2 is completed.

In addition, in the above-described embodiment, the disk-shaped skeleton body 50 is formed from the porous sheet, sliced, and cut to perform skeleton body 50.
a is formed, and the foaming liquid is applied to the surface of the skeleton body 50a, but as shown in FIG. 5 (c),
A ring-shaped groove 54 that forms the outer shape of the skeleton body 10 is cut and formed on the skin layer side of a sliced sheet body 52 obtained by slicing a porous sheet into two front and back surfaces, and a foam liquid layer 20a is formed thereon. In this way, the sheet body may be cut by thermocompression bonding at the position of the groove 54 after the drying treatment, and the puff may be manufactured by performing front and back surface treatments such as cutting processing as necessary. This makes it suitable for mass production of puffs.

Further, when the coating layer 20 is formed by the method shown in FIGS. 5 (b) and 5 (c), the skin layer shown by reference numeral 22 in FIG. Therefore, it is possible to apply makeup on the skin layer 22 forming surface even to a narrow portion such as the base of the nose or between the eyebrows and the eyes.

In addition, in the above embodiment, the coating layer 20 is the skeleton body 10.
The outer peripheral edge portion of the NBR is covered with a structure, but as shown in FIG. 6, a coating layer 20 that is mechanically foamed in a flat state is formed on the surface of the NBR porous skeleton body 10. It may have a structure as described above.

Further, in the above-mentioned embodiment, the case where the polyurethane porous coating layer 20 is formed on the surface of the NBR porous skeleton 10 has been described, but the skeleton 10 and the coating layer 20 are limited to NBR or polyurethane. Instead, various rubber foams, urethane foams, vinyl chloride foams, etc. may be used.

Further, the skeleton body 10 and the coating layer 2 that constitute the puff
The thickness of 0 can be set to any thickness in consideration of flexibility and elasticity of the entire puff.

[Effect of device]

As is clear from the above description, according to the present invention, a cosmetic applicator that can be used properly according to the type of cosmetics and user's preference and has a particularly excellent feeling in use and withstands long-term use is obtained. To be

In addition, since the exposed surface of the skeleton is formed by cut surfaces in which pores are uniformly dispersed, the cosmetic is uniformly impregnated and held in the skeleton, and it is possible to apply the cosmetic without uneven coating using the skeleton side. It will be possible.

In addition, since a skin layer (barrier layer) with very fine mesh is formed on the joint surface between the skeleton and the coating layer, the skeleton-side cosmetic material and the coating layer-side cosmetic material do not mix with each other, and The usage according to the type and user's preference is guaranteed for a long time.

Further, since the outer peripheral area of the applicator is formed of the coating layer having fine eyes, it is possible to apply a smooth touch evenly on a narrow portion such as the base of the nose or between the eyebrows and the eyes.

Further, since two skeleton bodies are formed from one synthetic resin porous body, the production efficiency of the applicator is good.
