Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a face mask mainly used by women as a beauty product.

[0002]

2. Description of the Related Art Most conventional face masks are made of a non-woven fabric having a flat surface, and in order to closely adhere to a face having various curved surfaces (concavities and convexities), a cut is made or top and bottom are made. It was necessary to divide and manufacture.

[0003]

This is a convenient method for inexpensively manufacturing a face mask which is often used as a disposable one, but "disposable" is not suitable for the times. In addition, since the non-woven fabric does not have elasticity, it is "difficult to adhere to curved surfaces and irregularities of the face", "cannot cover under the chin and neck", or "move around while using a face mask" There is a problem such as "I can't do it."

Apart from this, in recent years, a photocatalyst having an excellent bactericidal action and deodorant action has also attracted attention in the beauty industry.

However, when a photocatalyst is applied to a conventional face mask, it is uneconomical to use a relatively expensive photocatalyst for a disposable face mask, which has a long-lasting effect, and the manufacturing cost of the face mask is reduced. The result will be a significant increase.

The present invention has been made in view of the above problems, and provides a face mask which has better adhesion to the face than conventional face masks and can be used repeatedly. Is the main issue.

[0007]

In order to solve the above-mentioned problems, a face mask according to claim 1 is made of a stretchable material.

According to the present invention, since the face mask is made of a stretchable material, it can be more closely attached to the face than a face mask made of a conventional non-woven fabric.

In the invention described in claim 1, as described in claim 2, the material is cotton, kapok,
Linen, ramie, hemp, jute, palm, rush, Manila hemp, sisal, New Zealand hemp, ropeoma, wool, goat hair, mohair, cashmere, alpaca, angora, camel, vicuna, silk, down, feather, tencel, lyocell, rayon , Viscose rayon, cupra, copper ammonia rayon, regenerated protein fiber, chitin fiber, mannan fiber, acetate, triacetate, promix, polyester, acrylic, nylon, vinyl chloride, vinylidene, polyethylene, polypropylene, polyclar, aramid, polyurethane,
It is preferable that the material is one material selected from the group consisting of rubber or a synthetic material of two or more materials selected from the group.

Further, in the invention described in claim 1 or 2, as described in claim 3, it is preferable that the invention is formed in a cylindrical shape or a bag shape so as to cover the face.
With such a shape, the face mask does not slip off the face even when moving around with the face mask attached.

Further, in the invention according to any one of claims 1 to 3, as described in claim 4, a photocatalytic function comprising at least a photo-semiconductor powder in a portion contacting the face. It is preferred that the body is attached.

Thus, by adhering the photocatalyst functional body to the part in contact with the face, it is possible to promote the beauty of the face by the bactericidal action and deodorizing action (organic substance decomposing action) of the photocatalyst functional body. It is especially effective for acne and skin irritation.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The face mask of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing a first embodiment of a face mask of the present invention.

The face mask 1 of the present invention is characterized by being made of a stretchable material. The type of material is not particularly limited, and it is not particularly limited as long as it has elasticity and can cover the face in a close contact state, but it can be reused by washing or washing after use. It is necessary to have durability. Specifically, cotton, kapok, linen, ramie, hemp, jute, palm, rush, Manila hemp, sisal,
New Zealand hemp, ropema, wool, goat hair, mohair, cashmere, alpaca, angora, camel, vicuna, silk, down, feather, tencel, lyocell, rayon, viscose rayon, cupra, copper ammonia rayon, regenerated protein fiber, chitin fiber , Mannan fiber, acetate, triacetate, promix, polyester, acrylic, nylon, vinyl chloride,
One material selected from the group consisting of vinylidene, polyethylene, polypropylene, polyclar, aramid, polyurethane, rubber, or a synthetic material of two or more materials selected from the group can be used, and among them, silk is It is preferable because it itself is gentle on the skin. The term "stretchable material" as used in the present invention, in a strict sense, allows a material to have a degree of freedom of deformation depending on a knitting method or a weaving method, even when the material itself does not have elasticity. Any material can be used.

Regarding the shape of the face mask,
The present invention is not particularly limited as long as the shape can cover the face. For example, as shown in FIG.
The shape may be a substantially elliptical shape that matches the average size of the face, and if necessary, the portions 3 located on both eyes and the portion 4 located on the mouth may be cut out. Further, the part 5 located on the nose may be convex in advance.

The face mask 1 as shown in FIG. 1 is convenient because the material has durability and can be reused by washing or washing after use.

Further, in the face mask 1 of the present invention, a portion contacting the face (face mask 1 shown in FIG. 1
In the above, it is preferable that the photocatalyst functional body 20 made of at least photo-semiconductor powder is attached to the back surface). By adhering the photocatalyst functional body 20 to the portion in contact with the face, the bactericidal effect of the photocatalyst functional body 20,
The deodorizing effect can be utilized for beauty, and it is also possible to treat acne, skin inflammation and the like. Also, when using a face mask made of conventional non-woven fabric, it was necessary to apply lotion, acne remedy, etc. to the face mask, but by attaching a photocatalyst function body, Can be omitted.

FIG. 2 is a schematic sectional view for explaining the photocatalyst functional body 20 used in the face mask 1 of the present invention.

As shown in FIG. 2, the photocatalyst functional body 20 is composed of a photo-semiconductor powder 20a, fine particles 20b acting as electrodes, and an adsorbing material 21.

As the optical semiconductor powder 20a, TiO 2 is used.
₂ , CdS, CdSe, WO ₃ , Fe ₂ O ₃ , SrTi
Examples thereof include O ₃ and KNbO ₃ . Among these,
It has been confirmed in animal experiments that TiO ₂ is chemically stable without being attacked by most acids, bases and organic solvents, and that TiO ₂ does not cause poisoning and is not carcinogenic. From this point of view, TiO ₂ is most preferable.

The fine particles 20b used as the electrode are usually metal fine particles. As the metal fine particles forming the electrodes, various metal fine particles such as gold, platinum, and copper can be used in addition to silver. Since water is required as one of the indispensable elements for the photocatalyst to exert its original function, it is necessary that the metal fine particles forming the electrode are stable and do not change with time in the presence of water. ,
Platinum is most preferable among the above-mentioned metal fine particles, but silver is preferable because it has the above-mentioned characteristics in consideration of economical efficiency, is nontoxic, and has bactericidal property itself.

It is also possible to use fine silicon particles instead of metal as the electrode. By using silicon instead of metal, the photocatalytic function body itself becomes cheaper, and when the photocatalyst treated body is used in water, "the ions contained in water react with the metal as the electrode. It is possible to solve the problem that the photocatalytic function deteriorates.

Besides silicon, carbon, which is the same group (group 4) as silicon in the periodic table, can be used as an electrode because it has similar properties to silicon.

Here, the electrode is not always necessary for the photocatalyst functional body. TiO ₂ as optical semiconductor powder
In the case of using, the crystal structure of TiO ₂ has anatase type and rutile type, and the anatase type has a photocatalytic function. The electrode functions to help the photo-semiconductor powder decompose organic substances and the like. However, when a large amount of anatase-type TiO ₂ is present in the photocatalyst functional body, TiO ₂
This is because it has a sufficient photocatalytic function and does not require fine particles that act as electrodes.

The adsorbent material 21 adsorbs not only bacteria, viruses and molds, but also objects to be treated such as malodorous substances and harmful substances.
It is used for holding. Examples of such adsorbent materials include apatite (apatite), ceramic powder such as zeolite or sepiolite, one or more selected from the group consisting of activated carbon and silk fiber-containing material,
These can be used in combination of two or more as necessary. The apatite used herein is preferably hydroxyapatite [Ca ₁₀ (PO ₄ ) ₆ (OH) ₂ ] which selectively adsorbs proteins such as bacteria, viruses and molds.
In addition to the silk fiber powder, the silk fiber-containing material includes a granular material, a gel material, and the like. The particle size of these adsorbent materials (when the silk fiber-containing material is a powder) is preferably 0.001 to 1.0 μm in view of ensuring a large surface area and good workability of deposition, and particularly 0.01
˜0.05 μm is preferable. The mixing ratio of the photosemiconductor powder and the adsorbent material is preferably 1 to 50 parts by weight, and particularly preferably 10 to 30 parts by weight with respect to 100 parts by weight of the photosemiconductor powder.

Here, the adsorbent material is not always necessary for the photocatalyst functional body. If allowed to adhere a photocatalyst function member by thermal spraying onto the substrate, the adsorption material, malodorous substances and harmful substances in the processing object adsorption, which is used to hold the photocatalytic function of the optical semiconductor powder (TiO ₂₎ This is because it does not need to be assisted when it is not necessary (for example, when the photocatalyst functional body is always in contact with the object to be treated).

Next, a method for attaching the photocatalyst functional body 20 onto the material will be described.

The photocatalyst functional body may be deposited on the material by thermal spraying without a binder, or may be deposited on the material as a paint containing the binder.

FIG. 2 shows a state in which a photocatalyst is adhered to the surface of the base material 2 by thermal spraying. For example, fine particles of titanium oxide (TiO ₂ ) having a melting point of 2000 ° C. or less (5 to 50 μm) on the material 2. ), And metal fine particles 1 to 10 μm
And are ceramics melted at about 2900 to 3000 ° C. by a gas spraying method using oxygen, acetylene, or the like. In the sprayed state, the photocatalyst particles 20
Is composed of titanium oxide particles 20a acting as one electrode and metal particles such as silver particles 20b supported by the titanium oxide particles 20a and acting as the other electrode. The photocatalyst particles 2 form an electrochemical cell and, after thermal spraying, 30 to 40
The particles become flat laminated particles of μ and adhere to the base material 2 by the anchor effect while melting due to the high temperature of the gas. In the thermal spraying method by gas thermal spraying using oxygen, acetylene or the like, the gas torch for injecting molten photocatalyst fine particles and the base material are relatively moved so that the surface of the base material does not rise above 50 ° C. It also enables thermal spraying on paper, cloth, and the like. However, since it is gas spraying, the melting point of the powder of the raw material used is limited to 2000 ° C. or less. Plasma spraying is also possible by adjusting the relative velocity between the torch and the base material, but plasma spraying allows the raw material to be used to have a melting point up to about 3500 ° C.

Generally, in thermal spraying, powder adheres to the substrate due to the anchor effect, so that powder for thermal spraying is preferably in the form of lumps of 5 μm or more, and as the thermal spraying powder, all anatase is transferred to rutile. Things are used. Titanium oxide in the anatase crystal form (titania) has a strong photocatalytic action, but when the photocatalyst particles after spraying all have anatase crystals,
The decomposition action is too strong and the base material may be violated, so that it may not be put into practical use. However, the particle size of the anatase crystal particles, the spraying temperature, the substrate surface temperature, and the heating source used are 5 to 25 μm and about 2900 to 3000, respectively.
℃, 40 ~ 50 ℃ and by adjusting and selecting the gas,
Anatase crystals of 10-40% can be synthesized.
That is, about 75, which is the transformation point between anatase and rutile.
If the temperature exceeds 0 ° C, all the crystals will be rutile crystals,
According to the above-mentioned thermal spraying method, when particles of all rutile crystals are prepared and sprayed, 10 to 40% of anatase crystals are produced and the rest become rutile crystals. According to various experiments, X-ray analysis revealed that a weight ratio of anatase to rutile after spraying of 1: 3 is suitable.

Further, if the photocatalyst particles 20 are mixed with an adsorbent material 21 for adsorbing bacteria such as apatite, zeolite, activated carbon, harmful substances, odor, etc. and sprayed, the amount of anatase crystals is adjusted so as not to damage the base material. By doing so, the point where the photocatalytic action is weakened is reinforced.

That is, after spraying, the hydroxyapatite 21 adsorbs and holds the object to be treated such as bacteria, harmful substances and odors in the atmosphere, and the object to be adsorbed and held is 20 to 30.
Since the photocatalyst particles having the weight% of anatase crystals are decomposed, the photocatalytic action is reinforced. In order to enhance the photocatalytic action, it is necessary to increase the contact area where the particles come into contact with the object, but the thermal spraying method is preferable because a particle is formed finer and the surface area is larger than that in plasma spraying.

The titanium raw material does not necessarily have to be anatase and rutile, but an appropriate photocatalyst can be obtained by adjusting the ratio of anatase having a strong catalytic activity and anatase having a weak catalytic activity.

FIG. 3 shows a coating film of a coating material having a photocatalyst functional body formed on the base material 2. As can be seen from FIG. 3, the photocatalyst particles 20 are composed of titanium oxide 20a and silver particles 20b supported thereon, and can have the same structure as the particles in the case of thermal spraying shown in FIG. Here, 22 in the figure is a binder.

In general, the photocatalyst is a non-elution system, and the metal supported on the photo-semiconductor powder acts as an electrode, and it does not elute into the liquid and sterilize, but is generated in the presence of water. It has a bactericidal effect by radicals. On the other hand, a conventional elution-type antibacterial agent, for example, a mixture of an antibacterial agent made of zeolite supporting a metal having antibacterial properties such as silver, copper, zinc, etc. and a binder is applied to necessary places and dried. As shown in FIG. 4, the metal immediately dissolves in the liquid and exhibits immediate effect, but the effect is reduced in a short time, and the part where the metal is eluted becomes a nest of bacteria and causes harm. Becomes

As shown in FIG. 4, the photocatalyst functional body may be inferior to the conventional antibacterial agent in immediate effect, but since it is a non-eluting type, it hardly dissolves in the liquid,
The effect will last for a long time.

There is no particular limitation on the method of contacting the water after the agglomerate removal step with the above-mentioned photocatalyst functional body, and any method can be used.

In the present invention, the above-mentioned paint can be applied by dipping, gravure printing or the like at the stage of the raw material before forming the material into the shape of the face mask. Also, not only the stage of raw fabric, but also pellets, fibers,
It is possible to attach the photocatalyst functional body at any stage of cotton, yarn, and the final product.

FIG. 5 is a perspective view showing a second embodiment of the face mask of the present invention.

The face mask 50 shown in FIG. 5 is formed by forming a stretchable material 51 into a cylindrical shape. Even if necessary, the parts 52 located on both eyes and the part 53 located on the mouth are cut out. Good. Also, the portion 54 located on the nose
May have a convex shape in advance, or may be cut out in the same manner as the eyes and mouth. Further, it is also possible to cut out portions (not shown) located on both ears. Also,
Portion 5 of the cylindrical face mask 50 in contact with the face
The photocatalyst functional body 20 described above is attached to 5. In order to improve the photocatalytic effect, a photocatalytic functioning body may be attached to the entire face mask.

With such a shape, the hair can be projected to the outside of the face mask from the upper opening portion 56 of the cylindrical face mask, so that the hairstyle is not disturbed. Further, because of the tubular shape, the adhesion to the face can be further improved, and the face mask does not slip off from the face even if the user moves around while wearing the face mask.
The face mask can cover even the neck and chin.

FIG. 6 is a perspective view showing a third embodiment of the face mask of the present invention.

A face mask 60 shown in FIG. 6 is made of a stretchable material 61 in the shape of a T-shirt.
Even in this case, similarly to the face mask shown in FIG. 5, the portions 62 positioned on both eyes and the portion 63 positioned on the mouth may be cut off as needed. Further, the part 64 located on the nose may be formed in a convex shape in advance, or may be cut out similarly to the parts of the eyes and mouth. Further, it is also possible to cut out portions (not shown) located on both ears. Further, in the T-shirt-shaped face mask 60, the photocatalytic functioning member 20 described above is provided in a portion 65 in contact with the face.
Is attached.

By adopting such a shape, as shown in FIG.
It is possible to obtain the same effect as that of the cylindrical face mask shown in (1), and to add a design property to the conventionally dry face mask.

The face mask 70 shown in FIG. 7 has a basic structure similar to that of the face mask 60 shown in FIG. 6, and a description thereof will be omitted. However, the sleeve portion of the T-shirt is cut off, that is, the tank top. Shape (reference numeral 71 in the figure)
Part) is present. With such a shape, both ears can be put out from the portion 71 where the sleeve is cut off, which is convenient.

The embodiment described above is an example of the face mask of the present invention, and is not limited to the above embodiment. The above embodiment is an example,
Whatever has the same configuration as the technical idea described in the claims of the present invention and exhibits the same effect is included in the technical scope of the present invention.

For example, instead of the T-shirt shape, the shape of the face of a popular character or the shape of the face of an animal can be used.

[0050]

Since the face mask is made of a stretchable material, it can be more closely attached to the face than a face mask made of a conventional nonwoven fabric. Further, by forming the face mask into a tubular shape or a bag shape so as to cover the face, the face mask does not slip off from the face even when moving around with the face mask attached.
