A mushroom 36 is provided to prevent the food A ‥ A or the like from being flooded in the water of ‥ D. A photocatalyst functional body having an effect such as deodorization and sterilization is attached to the inner wall surface of the inner box 32, the inner wall surface of the inner lid 22, the surface of the saw blade 36, and the inner surface of the bag body 4 by a low-temperature spraying method. In addition, as shown in FIG. 4, the light source unit 24 can take in external light.
The cover 2 may be provided with a through hole. The light source unit 24 shown in FIG. 4 is provided at a substantially central portion of the inner lid 2, and penetrates through the outside and the inside.
And a transparent member 27 attached to the center in the thickness direction. Further, a light-storing material may be attached by providing a holding member for holding the light-storing material. As the light storage material, for example, a material obtained by applying a paint containing a light-emitting material to the surface of a rod material is used. As the phosphorescent material, a zinc sulfide-based pigment, or a material obtained by adding a radioactive substance to this pigment, or S

FIG. 5 shows a state in which a photocatalyst is adhered to the inner wall surface of the inner box 32 by a low-temperature spraying method. For example, titanium oxide (TiO ₂ ) having a melting point of 2000 ° C. or less is used.
Fine particles (5 to 25 μm) and metal fine particles (1 to 10 μm).
μm) is obtained by spraying 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 5 are composed of titanium oxide particles 5a acting as one electrode and a metal, for example, silver particles 5b, carried on the titanium oxide particles 5a and acting as the other electrode. The photocatalyst particles 5 form an electrochemical cell, become particles of 30 to 40 μm after thermal spraying, and adhere to the inner surface of the inner box 32 by the anchor effect while being melted by the high temperature of the gas. Incidentally, in the low-temperature thermal spraying method by gas spraying using oxygen, acetylene, etc., the gas torch for injecting the molten photocatalyst fine particles and the base material are relatively moved so that the surface of the base material does not rise to 50 ° C. or more. Therefore, thermal spraying can be performed on paper, cloth, and the like. However, the melting point of the raw material powder is limited to 2000 ° C. or lower.

In general, titanium oxide (titania) in the form of anatase crystals has a strong photocatalytic action. However, if all of the photocatalyst particles after thermal spraying have anatase crystals,
Since the decomposition action is so strong that the substrate is violated, it cannot be put to practical use. However, the particle size of the anatase crystal particles, the thermal spraying temperature, the substrate surface temperature and the heating source used are respectively 5 to 25 μm, about 2900 to 3000 ° C., 40 to 40 μm.
By adjusting and selecting the temperature at 50 ° C. and the gas, it is possible to make the anatase crystal 20 to 30%. That is, the anatase crystal changes to a rutile crystal at about 750 ° C. In the above-mentioned low-temperature thermal spraying method, when all the rutile crystal particles are prepared and sprayed, anatase crystals are generated in 20 to 30%, and the rest are rutile crystals. According to various experiments, X-ray analysis revealed that the weight ratio of anatase to rutile after thermal spraying was preferably 1: 3.

If the photocatalyst particles 5 are mixed with an adsorbent 51 for adsorbing bacteria such as apatite, zeolite and activated carbon, harmful substances, odors, etc., and sprayed, the amount of anatase crystals can be reduced so that the inner box 32 is not violated. Reducing it reinforces the point where photocatalysis is weakened.

That is, the adsorbent 51 after thermal spraying adsorbs and holds a treatment target such as bacteria, harmful substances, and odors in the atmosphere, and treats the adsorption-held treatment target with 20 to 30% by weight of photocatalytic particles having anatase crystals. Since 5 is 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 low-temperature spraying method is preferable because the particles are finer than plasma spray and a film having a large surface area is formed. .

Examples of the optical semiconductor powder include TiO ₂ and C
dS, CdSe, WO ₃ , Fe ₂ O ₃ , SrTiO ₃ , KN
bO _{3 and the} like. As the metal powder forming the electrode, various metal powders such as gold, platinum, and copper can be used in addition to silver. Metal powders as photocatalysts include:
Since water is required as one of the indispensable elements for the photocatalyst to exert its essential function, the metal powder needs to be stable without change over time in the presence of water. Among them, platinum is most preferable, but silver is preferable because it has the above characteristics in consideration of economy, and is non-toxic and has sterilization itself. In addition, the electrodes are not necessarily limited to metals, and it has been found that, for example, silicon Si can be used instead of these metals, and the silicon electrodes also cause electron transfer.
Silver, gold, platinum and the like are expensive and the use of silicon has a great economic effect.

The adsorbent is for adsorbing and holding bacteria, viruses, molds, and other substances to be treated, such as malodorous substances and harmful substances. As such an adsorbent, one or more selected from the group consisting of ceramic powders such as apatite (apatite), zeolite or sepiolite, activated carbon and silk fiber-containing materials can be used. They can be used in combination. Here, the apatite includes hydroxyapatite [Ca _10, which selectively adsorbs proteins such as bacteria, viruses, and molds.
(PO ₄ ) ₆ (OH) ₂ ] is preferred. Examples of the silk fiber-containing material include, in addition to the silk fiber powder, a granulated material, a gel material, and the like. The particle size of these adsorbents (when the silk fiber-containing material is powder) is not less than 0.001 in view of securing a larger surface area and considering good workability of application.
1.0 μm is preferable, and particularly preferably 0.01 to 0.05 μm. The mixing ratio of the optical semiconductor powder and the adsorbent is sterilized,
In order to suitably exhibit the deodorizing action, etc., the optical semiconductor powder 1
The adsorbent is preferably 1 to 50 parts by weight, particularly preferably 10 to 30 parts by weight, per 100 parts by weight.

The raw material of the thermal spray coating mixed with hydroxyapatite is, for example, 80% by weight of TiO ₂ , Ag10
% By weight and 10% by weight of hydroxyapatite are preferred.

FIG. 6 shows the photocatalyst particles 5 applied on the bag 4.
The photocatalyst particles 5 are composed of titanium oxide particles 5a and silver particles 5b carried thereon. The photocatalyst particles 5 are shown in FIG.
Can have the same structure as the particles in the case of the low-temperature spraying method shown in FIG. That is, silicon Si can be used as the metal electrode.

The photocatalyst particles 5 serve as an adsorbent 511
And is attached to the surface of the bag 4 by the binder 52.

Titanium oxide (TiO ₂ ), which is all in the form of anatase crystal, has an extremely strong oxidizing power and makes the bag 4 ragged.
The weight ratio of anatase to rutile in the titanium oxide particles as the raw material is preferably 20 to 50%: 50 to 80%. If the ratio of anatase is less than this, the photocatalytic action is weak, and if it is more than this, the photocatalytic action is strong. As a result, the binder 52 is decomposed and the ink or paint is immediately peeled off. Most preferably, the weight ratio of anatase to rutile is about 3: 7.

The paint contains, in addition to the optical semiconductor powder, the metal powder and the adsorbent, at least a film-forming component as the binder 52 and a dispersant, and if necessary, other components.

And the like. Examples of the dispersant include petroleum solvents, aromatic solvents, alcohol solvents, ester solvents, ketone solvents, cellosolve solvents, water and the like. When a powder coating is used, a solvent as a dispersant is not required. Other components include pigments, for example, inorganic pigments such as titanium dioxide, graphite, red iron oxide, chromium oxide, and carbon black; organic pigments such as Hansa Yellow, Nova Palm Orange, quinacridone violet, and copper phthalocyanine; Extender pigments such as calcium, barium sulfate, talc, clay, white carbon, etc.

Further, the photocatalyst function body is not directly attached to the inner wall surface of the box body, but a sheet material having the photocatalyst function body attached thereto is adhered to the inner wall surface. The base material such as a sheet material or a nonwoven fabric may be provided by being arranged inside the inner box. If a soft member such as a sheet material is selected as the base body, the photocatalyst functional body can be attached by printing without using low-temperature spraying or painting.

As the sheet material, a plastic film such as polyolefin, polyester, or polystyrene may be used. When this sheet material is attached to the inner wall surface, a rubber-based, acrylic-based, or silicon-based adhesive can be used.

Further, the printing ink comprises an optical semiconductor powder,
It contains at least a colorant and a vehicle as a binder 52 in addition to the metal powder and the adsorbent, and further contains other components as necessary.

As the colorants, those generally used as colorants for printing inks, for example, in addition to inorganic pigments and organic pigments,
Dyes such as oil-soluble dyes and disperse dyes can be used. Examples of the vehicle include oils, for example, drying oils such as linseed oil, semi-dry oils such as soybean oil, and non-drying oils such as castor oil.Resin, for example, rosin, modified rosin, natural resin such as gilsonite, or the like. Natural resin derivatives, phenolic resins,
Alkyd resin, xylene resin, urea resin, melamine resin, polyamide resin, acrylic resin, epoxy resin, ketone resin, petroleum resin, vinyl chloride resin, polyvinyl acetate, urethane resin, chlorinated polypropylene, chlorinated rubber, cyclized rubber, Examples thereof include a cellulose derivative and a reactive resin, and further include a plasticizer. Further, as other components, natural or synthetic wax components, desiccants, dispersants, wetting agents, crosslinking agents, gelling agents, thickeners, anti-skinning agents, stabilizers, matting agents,
Examples include an antifoaming agent, a color separation inhibitor, a photopolymerization initiator, and a fungicide. There is no particular mixing ratio of each of these components, and the same mixing ratio as that of a printing ink which is generally commercially available can be applied.

The total amount of the photosemiconductor powder, the metal powder and the adsorbent in the printing ink is 3 to 55% by weight based on the total amount of the printing ink in order to exert effects such as sterilization and deodorization and to secure appropriate printability. Preferably, it is particularly preferably 15 to 35% by weight.

The form and type of such printing inks are not particularly limited, and may be paste inks, solvent inks, or solvent-free inks, which are lithographic printing inks, letterpress printing inks, gravure printing inks, screen printing inks, and the like. It can be applied as intaglio printing ink and special printing ink. Among these, to achieve the object of the present invention most effectively, screen ink for paper,
Screen printing inks, such as plastic screen inks, glass screen inks, and fabric screen inks, are preferred.

It is to be noted that water is required for the catalytic function of the photocatalyst to exert its catalytic action. However, it is recommended that a water-absorbing polymer having a water-absorbing property be adhered to the surface of a sheet material or the like and that the sheet material be used with moisture. . For example, in FIG. 7, the photocatalyst particles 5, 5 and the adsorbent 511 are mixed into a printing ink as the binder 52 and printed on the surface of the sheet material 39 as the base body, and the water-absorbing polymer 53 is printed on the opposite surface. 53 is applied. The water-absorbing polymer 53 ‥ 53 has a large number of hydrophilic groups. When the water-absorbing polymer 53 ‥ 53 comes into contact with water, the powder of the water-absorbing polymer 53 ‥ 53 tends to spread, and the ion concentration inside the polymer contacts the water. Because it is higher, as a water-absorbing polymer in which moisture is absorbed inside by osmotic pressure,
Water-absorbing polymer composed of polyacrylic acid, polyacrylamide, poly N-vinylacetamide, polyethylene glycol, polyvinylpyrrolidone, polyvinyl alcohol, polyhydroxyethyl acrylate, polyvinylphosphon, polyvinylpyridine and other polymers Can be mentioned. As shown in FIG. 8, a powdery water-absorbing polymer 53 may be further mixed in the binder 52 in which the photocatalyst particles 5, 5 and the adsorbent 511 are mixed.

In general, the photocatalyst is a non-eluting system, and the metal carried on the photosemiconductor powder acts as an electrode, which does not elute in the liquid to sterilize it, but generates OH generated in the presence of water. -It exerts a bactericidal effect by radicals. On the other hand, a conventional dissolution type antibacterial agent, for example, a mixture of an antibacterial agent composed of a zeolite carrying a metal such as silver, copper, and zinc having antibacterial properties and a binder and dried at a required place As shown in FIG. 9, the metal immediately elutes into 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 instead. Becomes

As shown in FIG. 9, the photocatalytic functional body of the present invention may be inferior to the conventional antibacterial agent in terms of immediate effect, but since it is a non-eluting type, it hardly dissolves in the liquid. And the effect will last for a long time.

Therefore, a conventional antibacterial agent, for example, zeolite fine particles carrying metal ions (Ag, Cu, Zn) having an antibacterial action is mixed with photocatalyst particles (TiO ₂ + Ag) and subjected to low-temperature spraying or the like. If zeolite fine particles carrying the above metal ions are mixed in a binder and used as a printing ink or paint, it can be used as a quick-acting and long-lasting antibacterial and bactericidal agent.

In general, ceramics are excellent as a substance that emits far-infrared rays. However, the coating of the TiO ₂ powder, which is a photocatalyst functional body of the present invention, by a low-temperature spraying method has a radiation characteristic close to a black body. It also functions as a good far-infrared radiation coating. For far-infrared radiators, the ratio of anatase to rutile is not critical, and low-temperature sprayed coatings do not necessarily require apatite as an absorber and metal as an electrode in a photocatalyst. Since the photocatalytic functional body of the present invention uses a fine powder before radiation, a dense film can be obtained and a material having good surface roughness is formed, so that the actual radiation area is large and the emissivity is good.
The large surface area of the coating and the large actual emission area mean that the photocatalyst functions as a favorable photocatalyst because contact with the object to be treated is required.

The photocatalyst functional body described above is provided only on the inner surface of the bag 4, or provided on the inner surface of the bag 4 and the surface of the saw 36, or on the inner surface of the bag 4 and the inner surface of the inner box 32.
