Description

Cosmetic applicator {Makeup applicator}

The present invention relates to a cosmetic applicator wherein a film is adhered to one side of a sliced continuous foam in close contact with a concave portion, and the film surface is bonded to a substrate. More specifically, the present invention relates to a cosmetic applicator formed by thermal transfer of a film in close contact with the shape of a plurality of recesses on the slice surface.

In the applicator for cosmetics, when the amount of the cosmetic on the applicator is large, the applicator is smoothly slippery and cannot be uniformly applied. On the contrary, when the amount of the cosmetic on the applicator is small, resistance to the skin at the time of application increases, which is not preferable in view of the feeling of use.

For this reason, the development which improves the impregnation amount of the cosmetics with the cosmetic sponge by adjusting the foam structure, foam density, and thickness of this sponge so that the appropriate amount according to makeup may be apply | coated was made.

Specifically, the impregnation amount of the cosmetics is adjusted by adjusting the thickness of the slice of the continuous foam body by adjusting the thickness of the impregnation amount by improving the size and density of the bubbles with respect to the foaming of the NBR latex, the NR latex, and the wet foaming of the urethane. Has been adjusted.

Improving the impregnation amount to an appropriate range by improving the size and density of the former bubble has already been carried out by those skilled in the art, but there are still some improvements to adjusting the thickness of the slice of the latter continuous bubble. There is a point. In other words, the foam structure of the sponge and its physical properties are effectively used to improve the feel to the skin and to improve the coating properties, and can be adjusted to any amount of impregnation, so that there is a high interest in the industry, but cosmetics penetrate to the opposite surface and become dirty. It was a problem.

Accordingly, as a solution to this problem, the following methods are known, such as providing a film to form an impermeable layer.

end. A cosmetic puff applicator provided with a porous layer such as a thin wet foamed urethane layer having a skin layer formed by wet film formation on an elastic sheet via a hot melt resin film. Specifically, a porous layer in which a wet foamed urethane sheet having a thickness of 0.4 to 0.8 mm is formed on a knitted fabric (nylon tricoat half) by a solution coating method, or a polyurethane resin is applied to a release paper and wetted. Hot-melt resin which uses the porous layer formed into a film by this is a cosmetic puff formed by heat-welding to an elastic sheet using the heat-adhesive film of 30-70 micrometers in thickness (refer patent document 1).

I. The cosmetic sponge puff which thermally compresses the net-shaped pattern of width 1mm and a space | interval 3mm on the single side | surface of a continuous bubble sponge, and partially obstruct | occludes the bubble as a control of the impregnation amount without a film (refer patent document 2).

All. The cosmetic puff which bonds an application part sponge and a base material sponge through an impermeable layer, forms a film | membrane by the joining, and further hot-presses an uneven | corrugated pattern to an application part sponge, and adjusts a penetration amount (patent document) 3). In this embodiment, a NBR sponge having a thickness of 8 mm is used as a base sponge, and its skin layer is used as this impermeable layer, and a continuous bubble urethane sponge sheet which is an application part sponge is provided thereon, and the unevenness is applied to this application part sponge. The pattern is thermocompressed with a metal frame to compress the thickness to 0.5 mm.

Japanese Utility Model Publication No. 55-095611 Japanese Patent Application Laid-Open No. 09-164017 Japanese Patent Publication No. 2005-118433

Since this porous of the surface of the said cosmetic puff has a skin layer on the surface, since the surface and the inside have different foam density, and the surface layer is a dense layer, the cosmetics supplied to this cosmetic puff surface are It exists solely on the surface layer but is not impregnated in large quantities inside. In that case, this porous layer does not necessarily contribute to impregnation and application | coating of cosmetics. In addition, this cosmetic puff uses the film by general-purpose hot-melt resin instead of a slice sheet, and the film contact | adhered to concave part shape is not obtained.

Moreover, it cannot be said that it is coat | covered with hot melt resin along the shape of the inner surface of the recessed part of the surface of the porous body located in the elastic sheet side.

In addition, since the porous layer does not impregnate the cosmetics, the cosmetic puffs supply the cosmetics gradually to the skin in accordance with the method of applying strength to the skin, since the whole amount adheres to the skin immediately after the start of the application. As a result, it is difficult to achieve a uniform coating amount.

As for the said cosmetic sponge puff, air bubbles are occluded by the net compression of a net-shaped pattern, and a texture becomes hard. In addition, since the non-permeable layer is not provided on the back surface or the like, there is a problem that cosmetics that have penetrated from the surface come off from the side surface and the back surface, and are less practical than the technique of forming a film.

The above poly cosmetic puff may form an impermeable layer, and a porous layer having an uneven pattern may be provided by means of adhesion of a porous sheet through the impermeable layer. However, since this impermeable layer is a skin layer which is the main body of this cosmetic puff, it does not cover the concave part surface of the porous coating layer which touches on it, and the said space | gap between the surface coating and sponge of this porous coating layer is Since it is not extinguished by the thermal pressure of the uneven pattern, the cosmetic material impregnated in the puff at the time of use reaches this skin layer and fills this recessed part.

Thus, it is known as what was described in the said patent documents 1 and 3 to provide an application | coating tool which provided a certain film | membrane to a continuous bubble sponge, prevents penetration of cosmetics, and adjusts the impregnation amount. However, when this continuous bubble sponge is used as a slice sheet, the surface thereof has many concave portions larger than the bubble size of the foam formed due to the slicing blade being caught by the continuous foam when the continuous foam is sliced, and this continuous There is a concave portion in which the concave portion of the bubble size of the foam derived from the cross section of the foam sponge is present, and when a film is simply bonded thereon, voids originating in the concave portion formed by the compound between the surface of the slice sheet and the film are generated. Let's do it. This void is larger than the bubbles inside the sponge.

Since the voids excessively inhale the cosmetics during the use of the puffs, the cosmetics remain in the concave portion to be combined even after the application is completed by releasing the cosmetics from the puffs. In addition, since the shape of the face surface varies, such as a relatively flat part such as a ball or forehead, or a relatively convex part such as a chin or a nose, even if the same force is applied to the puff by hand, the puff is formed in the part of the convex part. Since the pressure exerted on the contact surface of the film becomes larger, more cosmetic is applied to the location of the convex portion.

In this manner, conventionally, uniform application is difficult, and many cosmetics may be applied depending on the part of the body.

In addition, when washing the puff after use, if a lot of cosmetics are left in the puff, it takes more time to wash, and if the cosmetics impregnated with washing are dried, the more cosmetics remaining in the puff, the more cosmetics The degree to which the puff is hardened by the dried material also increases, and further usability worsens.

In addition to this, there is a problem that the sound source is generated during use and wrinkles are generated by use.

This invention solves the said subject by formation of a film, and provides the cosmetic applicator with a film in which the coating amount which can arbitrarily adjust the impregnation amount was formed.

Means to solve this problem,

One surface of the slice sheet formed by slicing the continuous bubble sponge forms an application surface, and on the other surface of the slice sheet surface, the concave portion formed by roughening the surface by a slice blade, and the bubbles originally possessed by the continuous bubble sponge are cut. As a cosmetic applicator [claim 1] in which a film layer is provided in close contact with a shape of a recess formed by combining two kinds of recesses formed by a combination, and the side on which the film layer of this slice sheet is formed is joined to a substrate. The coating layer may be formed by thermal transfer [Claim 2], the thickness of the slice sheet layer may be 0.2 to 2.0 mm [Claim 3], and the coating layer by the thermal transfer may have a tensile fracture stress of 45 to 60 MPa and a tensile strength. It is polyester urethane resin of 500-700% of deformation | transformation deformation, and is 2-50 micrometers in thickness, and even if it adheres closely to the shape of the recessed part formed by combining the said 2 types of recessed parts, [Claim 4], The coating may contain an antimicrobial agent [Claim 5], the film forming surface of the slice sheet is bonded to the substrate, and the coated portion by the slice surface that is the facing surface of the film formation, or It has both surfaces, the film-forming surface of the said slice sheet is bonded to the base material, this base material is included in a part of support, and has the coating part by the slice sheet surface in the front part of a support part. 6-8] It is a cosmetic applicator.

Although the slice sheet surface is as flat as possible with the naked eye, as shown in FIG. 5, a wave-shaped recess exists. The shape of the recess is generated at the time of the slice by the slice blade, and the diameter and depth of the recess are different depending on the shape, specification, and slice conditions of the slice blade, but the recess is formed by cutting the bubbles originally contained in the slice sheet. It is significantly larger than diameter and depth.

In addition to these recesses, there are also smaller recesses formed by cutting the bubbles originally present in the continuous foam, and the recesses in which these two recesses are combined on the slice sheet surface of the present invention exist.

The surface is provided on the slice layer of the continuous foam body in close contact with the inner surface of the concave portion formed by the slice in this way to form a film.

As a result, cosmetics etc. are impregnated at the time of use than the application surface which is the surface of this slice sheet, and cosmetics etc. which were impregnated in continuous bubble advance toward the inside of a slice sheet.

At this time, the impregnated cosmetics and the like also penetrate into the continuous bubble portion, but the film formed on the recess portion is formed so as to block passages of the continuous bubbles leading from the slice sheet surface and the cosmetics connecting the recess portions to the recess portion. There is no case to fill this recessed part, and it does not impregnate excessively.

In this case, the user can apply a small amount supplied to the applicator to the skin or the like when applying the cosmetics, etc., so that the intended amount can be smoothly applied on the surface without slipping. Moreover, after use, since no cosmetics etc. remain in this recessed part, washing | cleaning is easy, and when it does not wash, hardening of the cosmetic applicator by drying of the residual cosmetics etc. can be prevented. Moreover, generation | occurrence | production of the sound at the time of use by cosmetics etc. which remain in this recessed part, and generation | occurrence | production of the wrinkle of the slice sheet by the presence of the recessed part can be prevented, and a feeling of use improves.

(Slice sheet layer)

The sponge which is a material of the slice sheet layer in this invention is well-known, such as the sponge by the Dunlop method of NBR and NR latex, the sponge by wet foaming of polyurethane, and the sponge which processes the independent bubble of polyurethane into a continuous bubble. Sponge can be used. It is possible to arbitrarily adjust the properties of the sponge itself, such as the expansion ratio, and it is possible to adjust the amount of impregnation into the slice sheet layer by adjusting the expansion ratio.

Such a sponge is sliced with a slice blade to make a thickness of 0.2 to 2.0 mm, more preferably 0.2 to 1.0 mm, to obtain a slice sheet layer in which both surfaces are sliced. Slicing is carried out for the purpose of adjusting the amount of impregnation such as cosmetics during use by removing the dense layer present on the sponge surface, that is, the skin layer, and adjusting the thickness. It is difficult to make thickness of a slice sheet layer less than 0.2 mm, and when it is 2.0 mm or more, it is not useful for adjustment of an impregnation amount, and it is unpreferable. Moreover, if it is not a continuous bubble, it becomes difficult to fully impregnate and hold | maintain cosmetics etc ..

As described above, the surface of the slice sheet has large irregularities caused when the bubbles of the continuous foam sponge are cut by the slice blades, and this blade is caught on the wall surface of the bubbles, and the irregularities are irregularities due to the bubbles of the sponge. Greater than

(Thermal transfer sheet)

The thermal transfer sheet is a member for providing a thermal transfer layer, which is a coating layer, on the one side of the slice sheet layer for the purpose of not permeating cosmetics or the like.

This thermal transfer sheet is a sheet which uses heat-resistant resin films, such as PET, as a base film, and forms a mold release layer and the heat-transfer resin layer in order on the single side | surface of this base film.

As for the thickness of this heat resistant resin film, 20-30 micrometers is preferable from what needs to have flexibility, and a release layer isolate | separates this base film and a heat transfer layer at the time of thermal transfer, and removes this heat transfer layer from this base film. It is a layer to bet.

The release layer lowers the adhesive force between the base layer and the thermal transfer layer by melting by heating, thereby facilitating peeling of the thermal transfer layer.

As such a release layer, the release layer which may be liquefied at the time of thermal transfer and obtains the soft cushion property may be sufficient, for example, it becomes a low melting polymer which is solid at normal temperature, and becomes a liquid by the heat at the time of thermal transfer, and the unevenness | corrugation which exists in a slice sheet surface is formed. It needs flexible cushioning property to adhere to. By this action, a coating layer can be thickened especially in the recessed part, and it becomes possible to reduce the depth of the recessed part.

As such a mold release agent, it is a low-density polyethylene resin whose melting | fusing point is 60-100 degreeC, For example, UBE® polyethylene UM8928 of melting | fusing point 69 degreeC, UBE® polyethylene UM8420 of melting | fusing point 94 degreeC, (Ube Maruzen Polyethylene Co., Ltd.) Product). As for the thickness of a mold release layer, 25-40 micrometers is preferable.

In addition, when the thermal transfer layer does not form a film in close contact with the concave portion of the concave-convex portion present on the surface of the slice sheet, and the continuous bubble communicates with the concave portion, a problem originating in the concave portion, that is, the concave portion in the slice sheet By communicating with the continuous bubble, the space formed by the recess is excessively filled with the cosmetic impregnated through the continuous bubble, thereby being excessively applied, or cosmetics or the like remain in the recess even after use. Generate. However, according to the present invention, if a film in close contact with the concave-convex shape of the unevenness is formed so that the continuous bubbles do not communicate with the concave portion, the concave portion is not filled with an excessive amount of cosmetics, and this problem is solved. .

(Film layer)

As mentioned above, since a coating layer is a layer which functions in close contact with the shape of the recessed part which exists in the slice sheet surface, the coating layer which exists in this recessed part is thick, and the coating layer which exists in the convex part is formed relatively thin. The thickness of a coating layer is 2-50 micrometers, More preferably, it is 2-20 micrometers, This thickness is an average thickness and is the same thickness as the thickness when it was formed on the base film through the release layer before thermal transfer.

As a result of the formation of the coating layer in close contact with the shape of the recess, the passage communicating with the slice sheet is filled, so that the recess is not in communication with the bubble. And when using a cosmetic applicator, since the cosmetics etc. which are impregnated to the surface layer formed from the slice sheet do not reach to this recessed part, they do not remain in this recessed part, and the impregnation determined by the thickness of a slice sheet is carried out. It becomes possible to apply | coat correctly according to an amount and a predetermined coating amount. At the same time, it is possible to prevent excess cosmetics from being sucked into the cosmetic applicator, to generate sound during use, and to prevent wrinkles on the coated surface as it is used.

As a component of the film used as a thermal transfer layer provided on such a mold release layer, it is in close contact with an unevenness | corrugation, and becomes an impermeable film. As a flexible resin film component, the polyester urethane resin in the range of 45-60 MPa of tensile fracture strength and 500 to 700% of tensile fracture deformation is preferable. More preferred tensile fracture strength is 48 to 53 MPa, more preferably tensile failure strain is 550 to 650%. If the tensile breaking force and the tensile breaking strain are smaller than this range, the film tends to be torn, and if it is large, the adhesion is poor, so that it is impossible to completely cover the recessed portion of the slice sheet so that the recess and the continuous bubble do not communicate. It is impossible to do. In order to form the thermal transfer layer of thickness 2-50 micrometers which consists of this polyesterurethane, this resin is melt | dissolved in a solvent and apply | coated to the release layer surface on a base material sheet.

In addition, in the cosmetic applicator used once, superficial bacteria etc. on the skin adhered at the time of use exist. For example, when an aqueous cosmetic etc. are affixed to a cosmetic applicator, a cosmetic applicator produces odor by propagation of the fungus. Moreover, the cosmetic applicator which wash | cleans after use and contains water will generate | occur | produce odor similarly also when aerobic bacteria etc. which exist in this moisture propagate. However, if the coating layer contains an antimicrobial agent, the antimicrobial agent gradually diffuses into the cosmetic applicator and can prevent or sterilize propagation of superficial bacteria, aquatic bacteria and the like, thereby preventing the occurrence of odor.

The antimicrobial agent which can be used for such a use can select arbitrarily the well-known antimicrobial agents, such as silver antibacterial agents, such as silver zeolite and silver containing glass, and the antimicrobial agent which can be used for cosmetics. Among them, silver-based antimicrobial agents are preferred from the viewpoint of safety to the human body, such as antimicrobial properties, chemical stability and not irritating the skin.

Thus, it is necessary to mix | blend an antimicrobial agent with this coating layer from the viewpoint of prevention of generation of odor. For example, when the sponge layer is to be blended with an antimicrobial agent, when the sponge is a vulcanized foam, the antimicrobial agent and the sulfur compound react to lose antimicrobial properties. In addition, the antimicrobial agent is mixed in a method of obtaining a foam by a wet method. Even if desired, since the silver-containing antibacterial agent will also elute together with the soluble particles eluted to form bubbles in the liquid, the sponge layer does not have an antimicrobial agent and thus cannot exhibit antimicrobial properties.

In addition, a coating layer can select and contain a well-known resin additive, such as a fragrance | flavor, a coloring agent, and a filler, as needed, and when a coloring agent is used, it changes a color according to the surface of a cosmetic applicator, or forms on the surface of a cosmetic applicator. It becomes possible to draw a back.

(Thermal Transfer Method)

In the present invention, in order to form a film on one side of the slice sheet, a thermal transfer method may be employed, and examples of the thermal transfer method include a continuous transfer method and a stationary transfer method.

Either way, the coating layer softens to the extent that it can cover the concave shape of the slice sheet surface by heating, and in the case of the release agent layer functioning by heating, it is heated to a temperature at which the function can be expressed. As a result, it is necessary to adjust the heating temperature, the heating time, the operating speed, and the like of the thermal transfer sheet.

And in the case of the continuous transfer method, for example, the said heat transfer sheet of a mesh shape is superimposed on a mesh-shaped slice sheet, and it calenders continuously by thermal pressure under the temperature conditions of the speed of 15 mm / Sec, and the roller surface temperature of 180 degreeC. In this way, the coating film in close contact with the concave-convex portion and covering the concave portion shape can be transferred.

In the case of the stationary transfer method, when the slice sheet and the thermal transfer sheet are laminated and hot-pressed for 4 to 5 seconds at a temperature of 150 ° C., the coating film in close contact with the concave-convex portion and covering the concave portion can be transferred.

(Cosmetic applicator)

The cosmetic applicator of this invention impregnates cosmetics from an application surface as a puff, a tip, etc., and uses it to apply to the target site | part of a body. Of course, what is necessary is just to have the structure of this invention also in the case of cosmetic applicators other than a puff and a tip. In addition, the size and shape of a puff, a tip, and other cosmetic applicators, the structure of a hand-picked portion, and the like can be any known.

And the cosmetic applicator is what joins the film layer provided in the single side | surface of a slice sheet to the surface of a base material. Specifically, the coating layer is laminated on the substrate side so that the slice sheet appears on the surface of the substrate having a size that can be used as a puff or tip. As the lamination means, a means such as adhesion using a known adhesive such as olefin, rubber, acryl or the like, or welding is employed. When a part of a mold release agent layer remains on a coating layer at the time of thermal transfer of a coating layer, it is also necessary to select the adhesive agent which does not adversely affect the adhesive force side at the time of this lamination | stacking, for example.

As a component of the film used as the thermal transfer layer provided on a mold release layer, it adheres to the unevenness | corrugation of a slice sheet, and becomes an impermeable film. As the flexible resin coating component, polyester urethane resin in the range of the above-described tensile strength at breakage of 45 to 60 MPa and the tensile failure strain of 500 to 700% is preferable. If the tensile breaking force and the tensile breaking strain are smaller than this range, the coating is likely to be torn, and if it is large, the adhesion is poor and the shape of the recess of the slice sheet cannot be completely covered. This resin is melt | dissolved in a solvent and apply | coated in order to form the thermal transfer layer of thickness 2-50 micrometers which becomes this polyesterurethane.

As a cosmetic applicator, (1) the film forming surface is bonded to a base material, the foundation coating part using the slice surface which is a joining surface as an application part, (2) the film surface of a slice sheet is bonded to both surfaces of the base material, The base material is bonded to one end of the support and can be used as a cosmetic tip having the slice face as an application portion.

Moreover, it is also possible to fix the base material which has the holding part which consists of hard materials, such as resin, a metal, a wood, and the like, and fixed to the surface of the holding part as an applicator of a brush-shaped form.

It is possible to select and use a well-known antimicrobial agent, a fragrance | flavor, a coloring agent, a filler, etc. to the base material similarly to the said coating layer.

The present invention will be explained based on the drawings.

And the slice sheet layer 1 is formed on the surface of this base material through the film 2, and is shown. At the time of use, the holding part 6 is picked up with a finger, and the slice sheet layer 1 is impregnated with a cosmetic. At the time of use, a cosmetic etc. adhere to the finger and do not become dirty.

The cosmetic applicator of this invention bonds the coating surface of a slice sheet to both surfaces of (1) the coating apparatus for foundation which uses (1) the film formation surface to a base material, and uses the slice surface which is a joining surface as an application part, and (2) the base material. Then, the cosmetic applicator having the coating portions on both sides and (3) the coating surface of the slice sheet are bonded to the substrate, the substrate is covered with the support, and the coating portion can be used as a cosmetic tip formed on both sides of the support. The substrate may be a porous substrate such as NBR, NR, a sponge of polyurethane or a nonwoven fabric, or a non-porous substrate such as rubber or a flexible resin molded body. The substrate may be flexibly deformed along the surface of the skin to form a slice sheet layer on the surface of the skin. The material which can be pushed is mentioned. Although it demonstrates concretely by an Example, this invention is not limited to an Example.

The tensile breaking force in the present invention is measured based on JIS K7161, and the tensile breaking strain is also measured based on JIS K7161.

Example 1

(Thermal transfer sheet)

On one surface of 25-micrometer-thick PET film, the film of UBE (TM) polyethylene UM8928 (made by Ube Maruzen polyethylene Co., Ltd.) which is LDPE of melting | fusing point 69 degreeC as a flexible cushioning mold release layer was dry laminated, and the release layer of 30 micrometers was installed. In addition, on this release layer, as a polyester urethane resin, 50 MPa of tensile fracture stress and 600% of tensile fracture strain 600% of YL-2300 (manufactured by Toyo Boseki Co., Ltd.) was dissolved in methyl ethyl ketone as a 30% solution. After coating and drying, a film having a thickness of 15 µm was formed to obtain a thermal transfer sheet.

In Comparative Example 1, instead of the BAYLON UR-2300, a tensile failure stress of 42 MPa and a tensile failure strain of 355% Kuramiron® U8175 (Kuraray Co., Ltd.) were used, and the thickness was 15 µm. A film was formed.

(Formation of film by transfer)

As a slice sheet of the continuous bubble sponge, the polyurethane wet foam sponge was sliced to 0.7 mm. The thermal transfer sheet was laminated on this slice sheet and pressurized at 150 ° C. for 4 seconds to form an adhesive film having a thickness of 15 μm.

The slice sheet having the film thus obtained was bonded to the porous substrate to produce the following cosmetic applicator.

(1) The cosmetic application tool which bonded the film formation surface of this slice sheet to the NBR sponge of thickness 7mm as a porous base material was produced.

(2) The cosmetic application tool which bonded the film formation surface of this slice sheet | seat to both surfaces of the NBR sponge of thickness 7mm as a porous base material was produced.

(3) The film-forming surface of this slice sheet is bonded to an NBR sponge having a thickness of 1 mm as the porous substrate, the porous substrate is bonded over the length of 11 mm of one end of the support of the cosmetic molding tip, and the slice sheet surface is A cosmetic tip was used as the application part.

(evaluation)

Table 1 shows the results of measuring the residual amount of the liquid foundation liquid on the coated surface under the above production conditions (1) and (2).

Example 1 and Comparative Example 1 are sliced to the same thickness and have an applicator having a film, but the large amount of residual amount in the Comparative Example is not sufficient to cover the concave shape of the surface of the slice sheet of the film-forming surface, so that the impregnated cosmetic The reason is that the large concave portion resulting from the slice of the other surface of the slice sheet and the concave portion where the bubbles contained in the slice sheet are cut to reach the concave portion formed by the composite. In Examples, the liquid foundation could be effectively used by sufficiently covering the concave portion, and the residual amount of the cosmetic in the applicator after use could be lowered. In the conventional film formation, it is impossible to make the residual amount up to 0.012 ml / cm 2, and for example, as shown in Comparative Example 1, many cosmetics remained at 0.058 ml / cm 2.

Measurement condition of residual amount of cosmetics:

A liquid foundation of 0.8 g was placed on the coated surface of a known weight of the applicator sample having a diameter of 30 mm, and the applicator sample was picked up by hand and applied to the inside of the arm. The residual amount which is the amount of the liquid foundation remaining in the applicator after application | coating was calculated | required from the weight of the applicator before and after application | coating obtained by measuring the weight of the applicator after application | coating.

5 shows a cross-sectional view of a state in which a film is formed in close contact with the uneven portion according to the first embodiment.

(a) It is a photograph of the film layer surface formed in the single side | surface of a slice sheet, and can confirm the state which remains the unevenness | corrugation which arose in the surface by slice. The bonding state of the film layer and the slice sheet is shown by (b)-(d). These figures can confirm the state which the recessed part of the white-colored slice sheet surface contact | adhered to the black film layer. The coating layer surface reflects the unevenness of the surface of the slice sheet itself, and the coating layer surface also has irregularities as shown in (a).

6 shows the bonding state of the slice sheet surface and the coating layer obtained by the comparative example 1, and a space exists in the recessed part of the slice sheet under a black coating layer. For this reason, the film layer surface is flat, and the film layer surface reflects the unevenness | corrugation of the slice sheet layer surface, and is not an uneven | corrugated surface.

(Evaluation of applicability to skin)

According to the Example, the use evaluation of application | coating had no excess suction of cosmetics, and the residual amount could be 0.012 ml / cm <2>. The smaller the residual amount, the more uniform the application is possible even when the application method or the application site is different, and it is easy to wash after use and to remove the residual cosmetic, and even if it is dried without washing after use, Since the amount of the applied cosmetic is small, the degree to which the applicator hardens due to it is small, so that the usability of the next use is still good. In addition, the use of the coating device having the coating can be solved without the occurrence of sound or wrinkles by use.

On the other hand, in a comparative example, a residual amount is 0.058 ml / cm <2> and a large amount of cosmetics remain. Or when using, there exists a sound by a space | gap, or wrinkles generate | occur | produce from a space | gap, and has the subject of the applicator which has a film as it is.
