Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a cosmetic applicator using a porous material and a method for manufacturing the same.

[Conventional technology]

Conventionally, porous materials used for the application part of cosmetic applicators include blocks and sheets of various foams such as foamed urethane and foamed rubber, woven fabrics (for example, napped fabrics, etc.) and nonwoven fabrics, and raised or
Flocked and seeded grains are often used.

Depending on the purpose of the cosmetic applicator and the type of cosmetic, these porous materials such as foams, woven fabrics, and non-woven fabrics are processed by punching, drawing, sewing, and attaching handles to various cosmetic applications. It is formed as an application part of an applicator.

Specifically, cosmetic applicators formed by punching include those made by laminating two sheets of foam material of the same or different materials together, or those made by pasting together two sheets of foam material of the same or different nature, or a woven fabric or non-woven fabric called a top plate on the surface of the foam material. There is one that has a finger support sheet pasted on it.

Cosmetic applicators formed by drawing include those made by drawing a raised blanket or foam sheet made of various fibers into an arbitrary shape and pasting the edge of the drawing opening to a top plate.

Cosmetic applicators formed by sewing include face powder puffs, etc., which are made by cutting woven cloth into circles and sewing the periphery together, and then filling the inside with foam.

A cosmetic applicator formed by attaching a handle has an applicator at the tip of the handle, and is used as a make-up applicator for fine areas such as eye shadow, a putting puff, and the like.

[Problem to be solved by the invention]

However, these cosmetic applicators have the following problems in terms of quality and productivity with respect to their joint parts (i.e., bonded parts).

According to the conventional method, when bonding multiple sheets of foam formed by punching, adhesive is applied to the surface of one of the foams, and another foam is placed on top of it. It is joined with adhesive. In cosmetic applicators made using this method, the adhesive may penetrate into the foam, delamination (a phenomenon in which the bonded part peels off) occurs, or the amount of adhesive may increase in some areas. There have been many cases in which parts of the cosmetic applicator become hard or the adhesive protrudes from the periphery of the cosmetic applicator due to strong compression and pressing to enhance the adhesive effect. As a result, there was a problem in that the quality of the finished cosmetic applicator was difficult to be consistent.

In addition, in the manufacturing process of the method described above, it is necessary to uniformly apply the adhesive onto the foam, accurately overlap the foam to be laminated, and set the drying conditions. Although it is necessary to keep conditions constant (solvent volatilization conditions, etc.),
There were also problems in manufacturing because the reproducibility of the manufacturing conditions was extremely low and it took time and effort to set the manufacturing conditions.

On the other hand, when making a cosmetic applicator by pasting a top plate sheet for finger attachment on the surface of the foam, or by squeezing the foam sheet and pasting the top sheet on the edge of the squeeze mouth, the top plate A hot-melt adhesive is applied to the back of the sheet in advance, this top plate sheet is placed on the foam surface or the edge of the aperture mouth, and then heated from the top plate surface to melt the adhesive. The foam and the top plate are bonded together.

However, in this method, the hot-melt adhesive on the back of the top sheet is melted through the top sheet, which has poor thermal conductivity, so the heat causes material deterioration of the top sheet, and sometimes even the foam that comes in contact with the heating plate is damaged. It may cause deterioration. In addition, in order to enhance the heat bonding effect, the top sheet and the foam are strongly compressed, but this pressure causes the hot melt adhesive to bulge out, making it difficult to use for cosmetics. There is a problem in that the applicator gets dirty and the quality is difficult to stabilize.
On the other hand, if the degree of compression is lowered in order to prevent the adhesive from protruding as described above, the adhesion between the top plate and the foam will be insufficient, resulting in peeling. In this way, extremely delicate conditions had to be controlled, making production management difficult.

Further, when manufacturing a cosmetic applicator by sewing, there is a problem in that it takes time and effort to stitch the periphery of the woven fabric.

In addition, when manufacturing a cosmetic applicator with a chip-like applicator attached to the tip of the handle, problems similar to those of pasting together multiple sheets of foam formed by punching as described above may occur, and In some cases, the application part does not adhere well and the tip falls out of the handle during use.

In order to solve these problems, the applicant has
Previously, a cosmetic applicator and a method for manufacturing the same were proposed as disclosed in Japanese Patent Application Laid-Open No. 59-211407. According to the method disclosed in JP-A-59-211407, both sides of a thin metal plate are coated with a hot melt adhesive, and the hot melt adhesive layer is formed between the porous material that will become the coated part and the bonding member. The thin metal plates are placed in an alternating magnetic field in a stacked state, and the thin metal plates are heated to melt the hot melt adhesive layer, thereby bonding the stacked porous material, thin metal plates, and bonding member to each other. .

Therefore, in the cosmetic applicator manufactured by this method, a thin metal plate is interposed between the porous material serving as the application part and the bonding member, and between the thin metal plate and the porous material and A hot-melt adhesive layer is provided between the thin metal plate and the bonding member, and the porous material and the bonding member are bonded to each side of the metal thin plate by the hot-melt adhesive layer.

The cosmetic applicator disclosed in JP-A-59-211407 solves the problems seen in the conventional applicator mentioned above, but in terms of its function as an applicator,
Various new problems have arisen.

In other words, the porous material and the laminated member are laminated using hot melt adhesive applied to both sides of the thin metal plate, but when finished as an applicator, it is particularly difficult to laminate foam and foam, punching and polishing. When processed and finished, it is unavoidable that the thin metal plate is exposed at the periphery of the bonding area.

Therefore, when using the applicator, the exposed peripheral edge of the thin metal plate comes into contact with the skin, causing a problem of irritation.

Moreover, even if this thin metal plate is made extremely thin, it usually has a
It is up to about 7μ. Therefore, the irritation is quite strong, and since the metal is plate-shaped, it is very rigid considering the characteristics of metal, and the entire application area has too much stiffness and feels hard, making it difficult to use. In particular, it is not suitable when the application part is a small tip or when applying cosmetics to small areas using an applicator.

In addition, since the metal thin plate is thick in units of μ, the amount of heat generated by the magnetic field is large, and the temperature instantly becomes high, which tends to cause thermal damage to the coated material to be bonded. Moreover, since it is difficult to control the amount of heat generated, it is difficult to bond uniformly.

Furthermore, the thin metal plate is exposed around the periphery of the bonding area,
Although the sides of the metal sheet are visible, the entire sheet metal cannot be colored. Therefore, the metallic color appears on the side of the application area, which may not be liked by users because it feels cold or feels like it might hurt the skin.

Another problem is that since a thin metal plate is used, manufacturing costs are relatively high.

In addition to the invention disclosed in Japanese Patent Application Laid-open No. 59-211407, the applicant of the present invention has also disclosed the invention in Japanese Patent Application Laid-Open No. 59-211408 in order to solve the above-mentioned conventional problems.
We proposed the following cosmetic applicator and its manufacturing method. That is, according to the method disclosed in JP-A No. 59-211408, metal powder is kneaded into a thermoplastic synthetic resin having hot melt adhesive properties to form a hot melt adhesive sheet, and this sheet is used to form a porous sheet that will become the application area. Sandwiched between the material and the laminated member,
These are placed in an alternating magnetic field in a stacked state, and the metal powder is heated by an induced current to melt the metal powder-containing hot melt adhesive sheet, and the stacked porous material, metal powder-containing sheet, and bonded member are separated. Paste them together.

In order to melt the hot melt adhesive sheet using this method, a large amount of metal powder (for example, about 10 times the amount of resin) must be kneaded, otherwise the metal powder will not generate enough heat or it will take a long time to melt. It will take time. However, when a large amount of metal powder is kneaded, the hot-melt adhesive sheet becomes thick and hard, and as a result, the cosmetic applicator produced has too much stiffness throughout the application area and feels hard, making it difficult to use. There is a problem. Furthermore, similar to the cosmetic applicator disclosed in JP-A-59-211407, there is a problem in that metal powder is exposed at the periphery of the applicator and comes into contact with the skin, causing irritation. Also,
Another problem is that it is expensive because a large amount of metal powder is used.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems, and its purpose is to solve the problems of conventional applicators and to solve the problems proposed by the applicant of the present invention,
The object of the present invention is to provide an applicator and a method for manufacturing the applicator which eliminates all the problems found in the inventions disclosed in Japanese Patent Publication No. 211407 and Japanese Patent Application Laid-Open No. 59-211408.

[Means to solve the problem]

In order to achieve the above object, the cosmetic applicator of the present invention is a combination of a conductive sheet with a metal coating layer or a metal plating layer formed on the surface of a flexible base sheet and a hot melt adhesive, or a hot melt adhesive function. A porous material that will become the application part of a cosmetic applicator is bonded to a bonding member using a hot melt adhesive sheet that has a metal plating layer on its surface.

The bonded member may be a porous material or a top plate for placing fingers. When using porous materials,
A cosmetic applicator is obtained in which both sides serve as applicator parts.

The form of the cosmetic applicator of the present invention may be any conventionally known form, such as a puff with or without tape for finger insertion and having application parts on both sides, or a puff with application parts on only one side. It may be a puff with a top plate, or an applicator with a handle, in which the applicator is attached to the tip of the handle.

A metal coating layer or a metal plating layer is applied to the surface of the flexible base sheet or sheet having a hot-melt adhesive function, but these base sheets or hot-melt adhesive sheets may be in the form of a non-porous film or a perforated film. It may be in a shape or a net shape. In addition, if the porous material and the bonding member are to be firmly bonded, a non-porous film is preferable, and if a soft feeling is desired to be imparted to the applied area, a perforated or net-like film, Alternatively, it is preferable to use a porous hot melt sheet.

The conductive sheet or the hot-melt adhesive sheet having the metal plating layer may be placed over almost the entire application area of the cosmetic applicator, or may be placed only in the necessary areas. For example, if the porous material used as the application area is thin or rough foam, conductive sheets or metal plating should be applied over almost the entire surface of the application area to prevent cosmetics from passing through and to give the application area some firmness. A hot melt adhesive sheet having layers may also be included. Further, instead of forming a circular puff by sewing, only the peripheral edge of the puff may be bonded using a ring-shaped conductive sheet or a hot melt adhesive sheet having a metal plating layer. If only the periphery is used like this, the center of the application area is not bonded, so it remains soft as it was.

In addition, as a method for manufacturing the cosmetic applicator of the present invention, first, a metal coating layer or a metal plating layer is formed on the surface of a flexible base sheet, and then metal plating is performed directly on a conductive sheet or a sheet having a hot melt adhesive function. A hot melt adhesive sheet having a metal plating layer on the treated surface is prepared, and when the conductive sheet is used, a hot melt adhesive is applied to the conductive sheet, porous material, or laminated member, or a hot melt adhesive sheet in sheet form is prepared. An adhesive is prepared separately, and then the conductive sheet in combination with the hot melt adhesive or the hot melt adhesive sheet having the metal plating layer is sandwiched between the porous material and the bonding member, and these are stacked. The conductive sheet or the metal of the hot melt adhesive sheet is placed in an alternating magnetic field in a combined state, and the metal of the conductive sheet or hot melt adhesive sheet is heated, the hot melt adhesive is melted, and the laminated porous material and the bonding member are adhered to each other.

The metal coating layer is formed by vacuum evaporation, spitting, ion plating, or the like.

The metal plating layer may be formed by electroless plating.

[Effect]

It is technically possible for the metal coating layer or metal plating layer used in the present invention to have a thickness of about 50 Å to 3000 Å, preferably about 300 Å to 1500 Å.

As described above, the thickness of the metal coating layer or metal plating layer of the present invention is several thousandths to several tenths of that of the thin metal sheet previously proposed by the applicant.

Therefore, according to the cosmetic applicator of the present invention, the bonding part is different from the case where a conventional thin metal plate is used.
The cosmetic applicator does not give the skin a hard, irritating feeling like a metal plate, and the cosmetic applicator has an extremely good usability.

In the manufacturing method of the present invention, when the metal coating layer or metal plating layer sandwiched between the porous material and the bonded member is placed in an alternating magnetic field, an induced current is generated, resulting in hysteresis loss and eddy current heat generation. fever occurs. This heated metal melts the surrounding hot melt components. Then, the porous material and the bonding member can be bonded together using the melted hot melt adhesive.

The melting time may be very short, e.g.
Hot melt components can be melted in just a few tenths of a second. Therefore, the applicator can be manufactured with extremely high production efficiency.

In addition, in the method of the present invention, the metal coating layer and the metal plating layer are formed by vacuum evaporation, sputtering, ion plating, etc., or metal plating, so they can be formed more easily than in the production of thin metal plates.
Moreover, the manufacturing cost is extremely low.

[Example] Hereinafter, the present invention will be explained in detail based on the illustrated example.

The cosmetic applicator of the present invention is a combination of a conductive sheet 1 having a metal coating layer or metal plating layer 12 formed on the surface of a flexible base sheet 11 and a hot melt adhesive 2 (FIGS. 1 to 3); Or, using a hot-melt adhesive sheet 6 (FIG. 5) having a metal-plated layer 62 on the metal-plated surface of a sheet 61 having a hot-melt adhesive function,
A porous material 4 and a bonding member 5 are bonded to each other to form an application portion of a cosmetic applicator.

FIG. 1 is a sectional view of one embodiment of the cosmetic applicator of the present invention. In addition, in the drawings below Figure 1,
For clarity, the thicknesses of the base sheet 11, metal coating layer or metal plating layer 12, and hot melt adhesive layer 2 are drawn enlarged compared to the actual thicknesses of the porous material 4 and the laminated member 5. There is.

In the embodiment shown in FIG. 1, the porous material 4 is a foam, the bonding member 5 is also a foam, and is a cosmetic applicator (for example, a puff) with both surfaces serving as application parts. A conductive sheet 1 is contained in the center of this cosmetic applicator, and hot-melt adhesive layers 2, 2 which melt when heated are provided on both surfaces of the conductive sheet 1. Two foam bodies 4 and 5 made of foam are bonded together via the adhesive layers 2 and 2.

In this embodiment, the conductive sheet 1 consists of a flexible base sheet 11 and a metal coating layer 12 formed on one side of the base sheet 11.

As the flexible base sheet 11 in this embodiment, a film of polyester, polypropylene, polyethylene, etc. may be used. The thickness of the film is about 1 to 200 microns, preferably about 3 to 20 microns.

The material of the metal coating layer 12 includes aluminum, copper, iron, tin, zinc, nickel, stainless steel,
A material with good conductivity such as chrome is suitable. Since it is used as an applicator, aluminum material is particularly suitable in view of the problem of oxidation and associated rust.

The thickness of the metal coating layer 12 is approximately 50 Å to 3000 Å,
Preferably it is about 300 Å to 1500 Å. The thickness of this metal coating layer 12 is determined by the amount of hot melt adhesive 2,
It may be selected appropriately in consideration of heating time and the like.

The hot melt adhesive layer 2, which melts when heated and exhibits adhesive properties, may be made of a single substance or a derivative of a thermoplastic synthetic resin such as polyethylene, polypropylene, polyester, polyamide, acrylic, urethane, vinyl acetate, vinyl chloride, or the like, or a derivative thereof. Modified resins or those obtained by mixing these resins with rosin or some wax are suitable, and those that have a relatively low melting point and exhibit adhesive properties when heated are suitable.

The foams 4 and 5 to be applied are various synthetic resin foams such as foamed polyurethane, foamed polyethylene, foamed vinyl chloride, foamed polyvinyl alcohol or foamed cellulose, various foamed rubber bodies such as foamed acrylnitrile butadiene rubber or foamed natural rubber. , natural sponge, etc. are suitable. Further, the foams 4 and 5 serving as the application portions are not limited to the above-mentioned foams, but may also be those with hairs or grains planted on the surface of these foams.

Note that, instead of using foam as the porous materials 4 and 5, coating materials made of various woven fabrics, nonwoven fabrics, knitted fabrics, or those with fluffs or granules planted on the surface thereof may be used as the coating portion.

When the base sheet 11 of this cosmetic applicator is in the form of a non-porous film, the film 11 can prevent the cosmetic from penetrating to the opposite side when the cosmetic applicator is used.

Next, a method for manufacturing the cosmetic applicator shown in FIG. 1 will be explained.

First, a flexible base sheet 11 is prepared, and the metal coating layer 12 described above is formed on the surface of this base sheet 11. The coating may be formed by a vacuum evaporation method, a sputtering method, an ion plating method using high frequency excitation, or the like. That is, the metal is evaporated or scattered in an ultra-vacuum, a low-pressure container, or a rare gas, and then the base sheet 11 is
to form an extremely thin film of single crystal metal on the base sheet 11. In this way, the conductive sheet 1 consisting of the base sheet 11 and the metal coating layer 12 is obtained.

A resin having a hot melt adhesive function is melted on both sides of the conductive sheet 1 obtained by the above method, that is, the surface of the base sheet 11 and the surface of the metal coating layer 12, or a hot melt adhesive is dissolved in an organic solvent. Then, coating is performed using an appropriate known coating method. As the coating method, for example, a curtain coating method using a T-die extruder, heated roll coating, heated knife coating, or a method of dissolving a hot melt agent in an organic solvent and applying it by gravure coating may be used. In this way, an adhesive sheet is obtained in which the hot melt adhesive 2 is integrally provided on both sides of the conductive sheet 1.

Alternatively, instead of the above-mentioned coating, two resin sheets 2 having a hot-melt adhesive function are prepared, and these are bonded using an appropriate adhesive or by heat bonding (self-adhesion using the hot-melt adhesive sheet 2). Temporarily bonded and laminated to the surface of the base sheet 11 and the surface of the metal coating layer 12, respectively,
The conductive sheet 1 and the hot melt adhesive 2 may be integrated into an adhesive sheet.

In this way, an adhesive sheet is completed in which the conductive sheet 1 is located in the middle and the hot melt adhesive layers 2, 2 are formed on the surface thereof.

Next, the foam 4 and the adhesive sheet (hot-melt adhesive agent 2,
The conductive sheet 1, the hot melt adhesive 2), and the foam 5 are superimposed, placed in an alternating magnetic field in the superimposed state, and a current is induced in the metal coating layer 12 of the conductive sheet 1 by electromagnetic induction, creating a vortex. Generates heat through current and hysteresis loss. As a result, the hot melt adhesive layers 2, 2 on the surface of the conductive sheet 1 are heated and melted, so that the stacked foams 4 and 5 are adhered to each other.

The metal coating layer 12 may be heated in the alternating magnetic field by either high frequency induction heating or low frequency induction heating. In this case, although the heating temperature is sufficient to melt the hot melt adhesives 2, 2,
The metal coating layer 12 is heated to a temperature that does not melt or deteriorate the foams 4 and 5. Therefore, in order to prevent the foams 4, 5 from deteriorating, it is preferable to use a material having a lower melting point than the foams 4, 5 as the hot melt adhesive layers 2, 2 described above.

As described above, the conductive sheet 1 that generates heat melts the hot melt adhesives 2, 2 on its surface and adheres the foams 4, 5. At this time, if the whole is pressed a little and the pressed state is maintained until the once melted hot melt adhesive solidifies, the bonded parts will be firmly joined. When the adhesive hardens, the lamination is completed and the cosmetic applicator of the present invention shown in FIG. 1 is obtained.

As mentioned above, when the hot melt adhesive 2 is prepared integrally with the conductive sheet 1, the porous material 4
It is easy and convenient to handle when bonding the material and the bonding member 5 together.

FIG. 2 is a sectional view of another embodiment of the cosmetic applicator of the present invention. In this embodiment, the porous material 4 is a foam, the bonding member 5 is a thick nonwoven fabric, and the cosmetic applicator has application parts on both sides, similar to the embodiment shown in FIG. It is.

Note that instead of using a foam as the porous material 4, a coating material made of a thick non-woven fabric, woven fabric, knitted fabric, or a coating material with fluffs or granules planted on the surface thereof may be used as the coating portion.

At the center of this cosmetic applicator is a conductive sheet 1.
is included, and on both sides of this conductive sheet 1,
Hot melt adhesive layers 2, 2 that melt when heated
There is. The foam 4 and the nonwoven fabric 5 are bonded together via the adhesive layers 2, 2.

In this embodiment, the conductive sheet 1 includes a flexible base sheet 11 and a metal coating layer or metal plating layer 12 formed on both sides of the base sheet 11.
Consisting of

As for the material of the metal coating layer or metal plating layer 12, aluminum, copper, iron,
Good conductive materials such as tin, zinc, nickel, stainless steel, and chrome are suitable. Further, the thickness of the metal coating layer or metal plating layer 12 is about 50 Å to 3000 Å, preferably 300 Å to 1500 Å, as in the first embodiment.
It is about Å.

Next, a method for manufacturing the cosmetic applicator shown in FIG. 2 will be explained.

First, a flexible base sheet 11 is prepared, and a metal coating layer or metal plating layer 12 is formed on both sides of this base sheet 11. In this case, the metal coating layer 12 is formed by a method such as a vacuum evaporation method, a sputtering method, or an ion plating method using high frequency excitation, as in the first embodiment, or the metal plating layer 12 is formed by electroless plating or the like.

Separately, a resin sheet 2 having a hot melt adhesive function is prepared.

A sheet-like hot-melt adhesive 2, a conductive sheet 1 having a metal coating layer or metal plating layer 12 on both surfaces, and a sheet-like hot-melt adhesive 2 are sandwiched between the foam 4 and the nonwoven fabric 5, and these are overlapped. The conductive sheet 1 is placed in an alternating magnetic field, and a current is induced in the metal coating layer or metal plating layer 12 of the conductive sheet 1 by electromagnetic induction to generate heat. As a result, the hot melt adhesives 2, 2 are heated and melted, and the superimposed foam 4 and nonwoven fabric 5 are adhered to each other.

Note that the hot melt adhesive 2 is the first adhesive described above.
In the method of the embodiment, it is prepared integrally with the conductive sheet 1, and in the method of the second embodiment, it is prepared separately from the conductive sheet 1, but there is a method different from these methods. Alternatively, the hot melt adhesive 2 may be applied to the porous material 4 or the bonding member 5 in advance. The conductive sheet 1 may be sandwiched between the porous material 4 coated with the hot melt adhesive 2 and the bonding member 5, placed in an alternating magnetic field, and heated and bonded.

FIG. 3 is a sectional view showing still another embodiment of the cosmetic applicator of the present invention.

In this embodiment, the conductive sheet 1 consists of a flexible film-like base sheet 11 provided with a large number of holes 13, and a metal coating layer or metal plating layer 12 formed on one side of the base sheet 11. In addition, in order to form the metal plating layer 12 only on one side of the base sheet 11, when performing plating, the base sheet 11
All you have to do is mask the opposite side.

When bonding the porous material 4 and the bonding member 5 using the perforated conductive sheet 1 as described above, the hot melt adhesive 2 may be placed on both sides of the conductive sheet 1, or The hot melt adhesive 2 may be placed only on one side of the conductive sheet 1.

In the embodiment shown in FIG. 3, hot melt adhesive 2 is placed only on one side during manufacture, and porous material (foam) 4 and bonding member (foam) 5 are bonded together.

That is, the perforated conductive sheet 1 and the hot melt adhesive 2 are sandwiched between the porous material (foam) 4 and the bonding member (foam) 5, and the superposed state of these sheets is placed in an alternating magnetic field. Then, a current is induced in the metal coating layer or metal plating layer 12 of the conductive sheet 1 by electromagnetic induction to generate heat. As a result, the hot melt adhesive 2 is heated and melted. At this time, when the entire stack is lightly pressed, the molten hot melt adhesive 2 oozes out 2a to the opposite side through the holes 13 of the conductive sheet 1. The exuded hot melt adhesive 2a adheres to the porous material 4 or the bonding member 5 on the side where the hot melt adhesive 2 is not placed. On the side where the hot melt adhesive 2 has been placed in advance, the porous material 4 or the bonding member 5 is adhered by the hot melt adhesive 2. In this case, especially
It is preferable to maintain the pressed state until the hot melt adhesive once melted solidifies again.

In this way, the stacked porous material 4 and bonding member 5 are bonded to each other.

In addition, in the above method, hot melt adhesive 2
may be integrated with the conductive sheet 1 in advance by coating or adhesion as described above, or
It may be provided separately from the conductive sheet 1, or may be applied to the porous material 4 or the bonding member 5.

Figure 4 shows the base sheet 1 used in the present invention.
FIG. 1 is a plan view of one embodiment of No. 1;

The base sheet 11 of this embodiment is a net-like sheet. A metal coating layer 12 is formed on this sheet 11 by a method such as a vacuum evaporation method, a sputtering method, or an ion plating method using high frequency excitation, or a metal plating layer 12 is formed by electroless plating or the like. do.

When using this net-shaped conductive sheet 1, the hot melt adhesive 2 may be applied on both sides of the conductive sheet 1, as in the case of the perforated conductive sheet 1 described above, or only on one side. good.

When the porous material 4 and the bonding member 5 are bonded together using the perforated conductive sheet 1 shown in FIG. 3 or the net-like conductive sheet 1 shown in FIG.
A cosmetic applicator that is softer overall than when laminated using the non-porous film-like conductive sheet 1 can be obtained.

In particular, coating the net-like conductive sheet 1 with an adhesive to form a hot melt adhesive layer 2;
When the porous material 4 and the bonding member 5 are bonded together using this, the conductive sheet 1 and the hot melt adhesive 2 do not exist entirely inside the application area, but only partially (in the form of a net). ), resulting in an extremely soft cosmetic applicator.

Further, as the base sheet 11, a nonwoven fabric may be used instead of the non-porous film, perforated film, or net-like sheet. Then, a metal coating layer or a metal plating layer 12 may be formed on the nonwoven fabric to form the conductive sheet 1.

Even when a nonwoven fabric is used as the base sheet 11, the hot melt adhesive layer 2 can be integrally provided on the surface of the conductive sheet 1 by coating, impregnating, or laminating with a hot melt adhesive. Further, as described above, the hot melt adhesive 2 may be provided separately or may be applied to the porous material 4 or the bonding member 5.

FIG. 5 is a sectional view showing another embodiment of the cosmetic applicator of the present invention.

In this embodiment, both the porous material 4 and the bonding member 5 are made of thick nonwoven fabric, and both surfaces serve as application parts of the cosmetic applicator.

In the embodiment shown in FIG. 5, instead of the combination of the conductive sheet 1 and the hot melt adhesive 2 described above, a hot melt adhesive sheet 6 having a metal plating layer 62 on the surface is used to bond the porous material 4 and the bonding member 5. is attached.

The hot-melt adhesive sheet 6 is a sheet 61 having a hot-melt adhesive function that is metal-plated to form a metal-plated layer 62 on its surface.

The sheet 61 having a hot-melt adhesive function can be in any suitable form, such as a non-porous film, a perforated film, a net, a nonwoven fabric, or a foamed sheet.

Further, the metal plating treatment is preferably performed by electroless plating. The thickness of the metal plating layer 62 is about 50 Å to 3000 Å, preferably about 50 Å to 3000 Å, as in the first embodiment.
It is about 300 Å to 1500 Å.

To manufacture the cosmetic applicator shown in FIG.
First, a sheet 61 having a hot melt adhesive function
A hot melt adhesive sheet 6 having a metal plating layer 62 on the surface is formed by metal plating. This hot melt adhesive sheet 6 is sandwiched between the porous material 4 and the bonding member 5, and the porous material 4, the hot melt adhesive sheet 6, and the bonding member 5 are placed in an alternating magnetic field in a superimposed state, The metal plating layer 62 of the hot melt adhesive sheet 6 is made to generate heat. This heat generation causes the hot melt adhesive 61 to melt, and together with this, the porous material and the bonding member are pressed together. In this way, the metal crystals of the metal plating layer 62 sink into the molten hot melt adhesive layer 61 due to the pressure bonding, or cracks appear in the metal plating layer 62, and the hot melt adhesive 61 rises to the surface from there. I'm coming. Note that if a large number of pinholes are made in the hot melt adhesive sheet 6, the hot melt adhesive 61 will be more likely to rise to the surface. The hot-melt adhesive 61 bulging on the surface penetrates along the surface of the porous material 4 or the bonding member 5 or into the surface irregularities, thereby bonding the porous material and the bonding member to each other.

In addition, in FIG. 5, the metal plating layer 62 is on the surface of the hot melt adhesive layer 61, and the porous material 4 is
and is drawn in contact with the laminated member 5, but this shows the state in which the porous material 4, the hot melt adhesive sheet 6, and the laminated member 5 are laminated, and in the actual manufactured cosmetic applicator, As described above, the hot melt adhesive 61 is in contact with the porous material 4 and the bonding member 5.

The hot melt adhesive sheet 6 described with reference to FIG. 5 (that is, a sheet 61 having a hot melt adhesive function is metal plated to form a metal plating layer 62 on the surface) is described with reference to FIGS. 1 to 4. It can be used in place of the combination of the conductive sheet 1 and the hot melt adhesive 2 in the above embodiments and the embodiments described below.

FIG. 6 is a plan view of a cosmetic applicator having a top plate, and FIGS. 7 to 9 are cross sections taken along line A--A in FIG. 6. FIG. 6 is a cross-sectional view of another embodiment.

In the embodiment shown in FIG. 7, the porous material 4 serving as the application portion is a foam, and the bonding member 5 is a top plate serving as the surface on which the fingers are placed during application. Further, in this embodiment, a ring-shaped conductive sheet 1 and a ring-shaped hot melt adhesive 2 are used.

As the top plate 5, it is preferable to use a sheet material with a good feel, such as nonwoven fabric, woven fabric, synthetic leather, natural leather, or various synthetic resin sheets. Further, the surfaces of these top plates 5 may be subjected to a printing process.

〔Effect of the invention〕

As described above, the present invention provides a method for combining a porous material that serves as an application part in a cosmetic applicator and a bonding member (which may also be a porous material that serves as an application part, or a top plate for finger attachment, etc.). As a bonding technique, a metal coating layer or metal plating layer and a hot melt adhesive are combined, the metal coating layer or metal plating layer is heated by induction heating, and the hot melt adhesive is melted to bond the porous material and the bonding member. By combining these two methods, we have solved the problems that existed in the past.

The metal coating layer or metal plating layer used in the present invention has a thickness of about 50 Å to 3000 Å. As described above, the thickness of the metal coating layer or metal plating layer of the present invention is several thousandths to several tenths of that of the thin metal sheet previously proposed by the applicant. Therefore, according to the cosmetic applicator of the present invention, unlike the case where a conventional thin metal plate is used, the bonded part does not give the skin the hard and irritating feeling of a metal plate, and the cosmetic applicator does not have a feeling of use. is extremely good.

According to the present invention, since the metal layer is as thin as angstroms, the amount of heat generated is smaller than in the case of a thin metal plate with a thickness of .mu.m, and the temperature is less likely to rise significantly. Therefore, there is no risk that the coated material will be thermally destroyed by high temperatures.
The adhesion state can be adjusted by adjusting the time, and the coated materials can be bonded uniformly.

Further, according to the present invention, since the thickness of the metal layer is extremely small, the metal layer is exposed at the periphery of the bonding area, and even if the side surface of the metal layer is visible, the metal color is hardly noticeable. Furthermore, in the present invention, the base sheet and the hot melt adhesive sheet can be colored, so that by coloring these, the metal color on the side surface of the bonding area can be made less noticeable and a desired hue can be achieved. This makes it possible to create a colorful cosmetic applicator that is liked by users.

According to the present invention, when a non-porous film is used as the base sheet inside the cosmetic applicator, the film can prevent the cosmetic from penetrating to the opposite side when the cosmetic applicator is used.

In addition, when a perforated film, a net-like sheet, a woven fabric, a non-woven fabric, or the like is used as the base sheet or hot melt adhesive sheet having a metal plating layer, the application area of the cosmetic applicator will feel soft. It is also possible to apply adhesive to only one side of the base sheet.

Furthermore, since conventional compressed puffs are manufactured by heating the surface of a cosmetic applicator in a compressed state, the puff becomes compressed from the surface portion. On the other hand, according to the present invention, the metal coating layer or metal plating layer is heated by the metal coating layer or metal plating layer disposed inside the cosmetic applicator, so that the metal coating layer or the metal plating layer is heated by the metal coating layer or metal plating layer disposed inside the cosmetic applicator. A cosmetic applicator can be obtained in which the interior of the applicator part is compressed. Since the application section is heated from inside, there is no risk of deterioration or deformation of the material on the surface of the application section.

According to the manufacturing method of the present invention, when the metal coating layer or metal plating layer sandwiched between the porous material and the bonded member is placed in an alternating magnetic field, an induced current is generated, and the hysteresis loss and the eddy current generate a The heat generates heat, and the heated metal melts the surrounding hot melt components. Then, the porous material and the bonding member can be bonded together using the melted hot melt adhesive.

The melting time may be very short, e.g.
Hot melt components can be melted in just a few tenths of a second. Therefore, the applicator can be manufactured with extremely high production efficiency.

In addition, in the method of the present invention, the metal coating layer and the metal plating layer are formed by vacuum evaporation, sputtering, ion plating, etc., or metal plating, so they can be formed more easily than in the production of thin metal plates.
Moreover, the manufacturing cost is extremely low.
