Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a cosmetic applicator, particularly an applicator for make-up cosmetics.

[Conventional technology]

2. Description of the Related Art Conventionally, many applicators for make-up cosmetics, for example liquid cosmetics, are made of porous foams such as foamed rubber and foamed urethane. These cosmetic applicators are manufactured by punching, cutting, and polishing large pieces of foam into the shape of a puff, but these manufacturing processes create sharp points on the foam skeleton on the applicator's surface. parts are formed. Such sharp parts on the surface of the applicator cause skin irritation such as a tingling or stiff feeling when applying cosmetics.

In order to reduce irritation to the skin surface as mentioned above and obtain a cosmetic applicator with a good feeling of use, the applicant of the present application has already developed a structure in which the surface of the skeleton of a foam is made of a flexible material in Japanese Utility Model Publication No. 57-29687. It is proposed to cover it with resin.

[Problem that the invention attempts to solve]

As mentioned above, by coating the surface of the skeleton of the foam with a flexible synthetic resin, skin irritation such as tingling or stiffness felt when applying cosmetics is considerably reduced. However, even with this method, people with sensitive skin may still experience irritation, and even people with normal skin may experience irritation in sensitive areas of the skin, such as around the eyes. There is a need for cosmetic applicators that are less irritating and easier to use.

In addition, when covering the surface of the foam skeleton with a flexible synthetic resin, the thicker the coating layer is, the better to round off the sharply pointed parts of the foam skeleton on the surface of the applicator. It is good, but if the coating layer is too thick, the applicator will feel rough and the usability will be poor. Conversely, if the thickness of the coating layer is too thin, sharp points will not be rounded, and therefore irritation to the skin during application will not be reduced. Furthermore,
When forming a synthetic resin coating layer on a foam as described above, it is necessary to delicately adjust the viscosity, adhesion amount, etc. of the synthetic resin.

Furthermore, when applying liquid (including cream) foundations, cosmetic applicators made of foam are generally used, but the cosmetics are hardly retained on the skeletal surface of the foam; inside the pores of the body,
In other words, it enters the space between the skeletons and is held there. Therefore, a considerable amount of cosmetics ends up entering the space. Since the cosmetics enter the space between the skeletons, when applying the cosmetics, the foam is pressed relatively firmly against the face, and the foundation oozes out from within the foam. The déchon is coated with a foam skeleton. As a result, too much foundation is produced, resulting in uneven coating, and traces of the foam skeleton resulting in streak-like coating unevenness. Moreover, in order to cause the foundation to ooze out, the applicator must be strongly pressed against the skin to spread the application, which inevitably causes strong irritation to the skin.

This invention solves the above-mentioned problems and allows you to apply cosmetics by simply applying the cosmetic to the applicator, lightly applying it to the skin, and spreading it. To provide a cosmetic applicator that does not give a tingling or stiff feeling, has low frictional resistance when spreading a cosmetic, causes very little irritation to the skin, and has a good feeling of use.

Another object of the present invention is to provide a cosmetic applicator that can be freely applied to various cosmetics regardless of the material of the base material of the applicator.

[Means for solving problems]

According to the present invention, the spherical beads, or the spherical beads and the granular modifier are attached to the outer surface of the applicator base material, and the spherical beads remain almost completely spherical and are attached to the outer surface of the applicator base material. The above-mentioned problem has been solved by a cosmetic applicator which is characterized in that the applicator adheres to the cosmetic applicator so as to substantially uniformly cover the entire surface.

[Effect]

In the cosmetic applicator of the present invention, the spherical beads are attached to cover the entire outer surface of the applicator base material almost uniformly, so that it is the spherical beads that come into contact with the skin during application. Since the spherical beads have round surfaces, there are no sharp edges, and therefore, even when they come into contact with the skin, they do not give a tingling or stiff feeling, and are extremely less irritating to the skin.

In addition, when applying cosmetics, the spherical beads are in point contact with the skin, so the contact area between the skin and the applicator is small. stimulation is greatly reduced.

Furthermore, since spherical beads are attached to the outer surface of the cosmetic applicator of the present invention, the outer surface is not flat unlike conventional foam skeletons, but the spherical beads form fine irregularities. Since the unevenness holds the cosmetic on the outer surface of the applicator, the cosmetic can be applied by simply applying the cosmetic to the applicator, lightly applying it to the skin, and spreading it.

〔Example〕

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings. The drawings schematically represent the cosmetic applicator of the present invention, and the spherical beads are shown enlarged in size compared to the base material of the applicator.

FIG. 1 is a schematic sectional view showing an embodiment of the cosmetic applicator of the present invention. Spherical beads 3 are attached to the surface of an applicator base material 1 via an adhesive 2.

The applicator base material 1 of the present invention is made of porous materials conventionally used in cosmetic applicators, such as synthetic resin foams such as polyvinyl chloride, polyester, polyethylene, and polypropylene; NBR (acrylonitrile butadiene rubber); Rubber foams such as SBR (styrene butadiene rubber), NR (natural rubber), and silicone rubber; or fiber sheet materials such as woven fabrics, nonwoven fabrics, knitted fabrics, and cosmetic cotton can be used. In addition, solid sheet materials made of synthetic resins such as polyvinyl chloride, polyester, polyethylene, and polypropylene; solid sheet materials made of rubber such as NBR (acrylonitrile butadiene rubber), SBR (styrene butadiene rubber), NR (natural rubber), and silicone rubber; or synthetic paper made of synthetic resin pulp;
A paper sheet material such as ordinary paper made of natural pulp can also be used as the applicator base material 1.

The material of the applicator base material 1 may be appropriately selected depending on the type and nature of the cosmetic to be applied, the application location, etc.

As the adhesive 2, an emulsion type adhesive such as a polyurethane type, a polyester type, an acrylic ester type, or a solution type adhesive is suitable. Furthermore, the adhesive 2 may be one that becomes finely foamed after being applied. The adhesive 2 is applied to a desired thickness using a gravure printing method, a roll coating method, a spray coating method, a flow coating method, a dipping method, etc.
is applied onto the surface of the applicator base material 1.

Spherical beads themselves have recently been developed and commercialized, and are almost completely spherical microscopic powder particles.Currently, their uses include fillers, powder lubricants, adsorbents, and precision filtration materials. has been done.

There are two main methods for producing spherical beads: the building-up method and the breakdown method. Examples of the building-up method include a jet cooling method, a liquid phase reaction method, a jet drying method, an extrusion molding method, and a briquette sintering method. In the injection cooling method, materials such as plastics, urea, paraffin, rosin, etc. are melted and injected into particles by utilizing their surface tension and cooled to form spherical particles. The liquid phase reaction method is based on pearl polymerization, in which a synthetic resin is dried in a liquid and polymerized into spherical particles. In the spray drying method, a solution or slurry liquid of starch, cellulose, synthetic resin, etc. is sprayed into particles and dried to form spherical particles. The briquette sintering method is a method in which powder is solidified into a spherical shape and sintered. The extrusion molding method involves extruding plastic or the like to form pellets into spheres.

Depending on the material, it can be manufactured by pulverizing it and then finishing it into a spherical shape using a tumbler or using a spherical pelletizer.

Moreover, the spherical beads 3 are not limited to solid ones, and may be porous ones or microcapsule ones.

Porous spherical beads 3 can be produced, for example, by adding calcium carbonate powder, natural cellulose, etc. to a solution containing a synthetic resin, mixing and stirring to form spherical beads, and then immersing the spherical beads in an acid solution to form the spherical beads. It can be manufactured by eluting and removing calcium carbonate powder, natural cellulose, etc. For example, porous spherical beads can be produced with an average particle diameter of about 10 microns and pores between 0.01 and 0.5 microns in diameter.

It is also possible to produce porous spherical beads from cellulose or inorganic materials by adding a foaming agent to the synthetic resin or by selecting reaction conditions and sintering conditions.

Spherical beads used in the cosmetic applicator of the present invention 3
The material is not particularly limited, and examples include synthetic resins such as polyethylene, polypropylene, polyurethane, polyester, polyamide, polycarbonate, silicone resin, fluorine resin, phenol resin, acrylic resin, polystyrene epoxy resin, vinyl resin, benzoguanamine resin; cellulose. Compounds; starch compounds; protein compounds such as collagen; calcium compounds; inorganic compounds such as ceramics and glass; metals; rubber, etc. can be used.

The material of the spherical beads 3 may be appropriately selected depending on the cosmetic to be applied. For example, water-repellent paraffin, polyethylene, silicone resin, fluororesin, etc. are suitable for cream foundations and the like. When a fluororesin having oil repellency is used, cosmetics adhering to the applicator can be easily washed off. Water-absorbing proteins such as cellulose, collagen, and casein are suitable for summer foundations that use water. Additionally, using materials such as ceramic, glass, phenolic resin, polycarbonate, polystyrene, polypropylene, polyamide, etc. reduces the frictional resistance of the applicator, making it easier to apply and spread cosmetics on the skin, and is also suitable for pine surgery. .

Spherical beads used in the cosmetic applicator of the present invention 3
is almost completely spherical, and its diameter is 0.5~
A particle size of about 5000 microns can be used, preferably an average particle size of about 5 to 2000 microns. For example, in the case of applicators used for people with sensitive skin or for applying cosmetics to sensitive skin around the eyes, such as eye shadows, spherical beads 3 with a size of about 0.5 to 30 microns may be used, or liquid foundations may be used. The applicator for powder foundation is spherical beads 3 of about 30 to 100 microns, the applicator for powder foundation is spherical beads 3 of about 100 to 500 microns, and the applicator for pine surge is spherical beads of 500 microns or more. It can be set to 3. Note that the relationship between the cosmetic and the particle size of the spherical beads 3 is not limited to that described above.

Furthermore, when porous spherical beads are used, since they have pores, they have excellent water absorption and oil absorption.

In order to attach the spherical beads 3 to the surface of the applicator base material 1, the adhesive-coated applicator base material 1 is coated with an electrostatic flocking method, fluid dipping method, scattering using a sieve, etc. (scatter method), or using a spray gun. The spherical beads 3 may be attached by spraying or the like. Alternatively, the spherical beads 3 may be attached to the applicator base material 1 by spraying a mixture of the adhesive and the spherical beads 3, or by spraying the adhesive and the spherical beads 3 simultaneously with separate sprays. good.

The amount of adhered spherical beads 3 (distribution density) depends on the size of the spherical beads, the material of the spherical beads, the type of cosmetics (viscosity, properties, etc.), and the purpose of use of the applicator (for applying cosmetics, for pine surge, etc.) , taking into consideration the amount of cosmetics contained, etc., and selecting a material that provides a good texture. The spherical beads 3 are provided on the surface of the applicator base material 1 to prevent the applicator base material 1 from coming into direct contact with the skin when applying cosmetics. Therefore, in general, when the particle size of the spherical beads 3 is small, the spherical beads 3 are attached relatively densely, and the gaps between the spherical beads 3 are made small. Moreover, the cosmetics are better absorbed when the spherical beads 3 are attached with appropriate gaps, rather than when they are attached in contact with each other with no gaps between them. However, if the distance between the spherical beads 3 is too large, the cosmetic will become streaky when applied to the skin. It is preferable to cover the entire outer surface of the applicator base material 1 almost uniformly without opening too much.

Note that if the applicator base material 1 is a foam and the adhesive 2 is applied by closing the pores of the foam, the spherical beads 3 will be attached to the applicator base material 1 regardless of the pores of the foam. adheres to the entire outer surface of the However, if the adhesive 2 is applied along the foam skeleton without blocking the pores of the foam, if the particle size of the spherical beads 3 is smaller than the pores of the foam, the spherical beads 3 It adheres along the body skeleton and also to the pores on the surface of the foam.

In addition, when the adhesive 2 is made of foamed material, the adhesive 2 has some air permeability, and furthermore,
This results in a cosmetic applicator that has an even softer feel.

In the embodiment shown in FIG. 2, spherical beads 3 and 4 having different average particle diameters are attached to the surface of the applicator base material 1. For example, average particle size
Spherical beads 3 of 60 microns and spherical beads 4 of average particle size of 30 microns are attached to the applicator base material 1 in a mixed state.

Instead of using spherical beads of different particle sizes as shown in FIG. 2, spherical beads of different materials may be attached to the applicator base material 1 in a mixed state.

In this way, spherical beads of different particle sizes and materials are combined taking into account the viscosity, properties, etc. of the makeup cosmetic, and by adhering them to the surface of the applicator base material 1 in an appropriately mixed state, it is possible to improve the texture and makeup. It is also possible to obtain a cosmetic applicator that contains even better ingredients.

FIG. 3 is a schematic sectional view showing still another embodiment of the cosmetic applicator of the present invention. In this embodiment, in addition to the spherical beads 3 on the surface of the applicator base material 1, the applicator base material 1 has properties and texture (touch) for cosmetics.
A modifying material 5 is attached to improve the

For example, modifiers for summer cosmetics that use water include cross-linked polymers of carboxyl methylcellulose, alkali metal carboxylate salts, vinylon, rayon, sponge, etc., which have good water absorption and water retention properties. Enriched granules can be used.
In addition, known lipophilic powders can be used as applicators for oil-based cosmetics.

In the case of a powdery modifier, it is preferable that its size is the same as or smaller than the spherical beads 3. Furthermore, if the mixing ratio of the modifier with the spherical beads 3 is too large, the smooth texture of the spherical beads 3 cannot be fully utilized. In particular, when the powder modifier is larger, there is such a tendency, so the amount of the modifier should be limited to about the same amount as the spherical beads 3.

In the cosmetic applicator of the present invention shown in FIG.
has been established. This synthetic resin layer 6 is made up of spherical beads 3.
It can be formed by adhering to the applicator base material 1 with the adhesive 2, and then applying a very thin solution of a flexible synthetic resin such as acrylic, polyurethane, polyamide, polyester, etc. onto the spherical beads 3. By changing the viscosity of the synthetic resin liquid, the synthetic resin layer 6
You can change the coating state of. For example, as shown in FIG. 4, it is also possible to thinly cover the entire surface of the spherical beads 3 while following the surface thereof. Alternatively, if the viscosity of the synthetic resin liquid is made very low and applied thinly,
The synthetic resin liquid flows down along the surface of the spherical beads 3 and spreads over the adhesive 2 at the base of the spherical beads 3, leaving the tops of the spherical beads 3 exposed.

When the synthetic resin layer 6 is provided in this way, the spherical beads 3 are covered with the synthetic resin layer 6 and their base portions are fixed, making it difficult to peel them off from the applicator base material 1.

[Effect of idea]

According to the present invention, the spherical beads are attached so as to almost uniformly cover the entire outer surface of the applicator base material,
Since spherical beads have round surfaces and no sharp edges, they do not give a tingling or stiff feeling when they come into contact with the skin during application, and are extremely less irritating to the skin.

In addition, when applying cosmetics, the spherical beads are in point contact with the skin, so the contact area between the skin and the applicator is small, and therefore the frictional resistance when spreading the cosmetics is small, and the skin Very little stimulation. As described above, the cosmetic applicator of the present invention is extremely comfortable to use.

Furthermore, according to the present invention, since spherical beads are attached to the outer surface of the cosmetic applicator, the outer surface is not flat unlike conventional foam skeletons, but minute irregularities are formed by the spherical beads. There is. Since the cosmetic is retained on the outer surface of the applicator by these fine irregularities, the cosmetic can be applied by simply applying the cosmetic to the applicator, lightly applying it to the skin, and spreading it.

Furthermore, by selecting the material, particle size, etc. of the spherical beads to be attached to the surface of the cosmetic applicator, it is possible to freely adapt the cosmetic applicator to various cosmetics, regardless of the material of the applicator base material. Further, in the past, the material of the base material of the applicator was limited depending on the type of cosmetic, but according to the present invention, the material of the base material of the applicator can be arbitrarily selected.
