【発明の属する利用分野】
本発明は、毛髪等を梳き整髪する櫛及び整髪ブラシ等の整髪具に関するものである。
【０００２】
【従来の技術】
従来の「櫛」あるいは「コーム」と呼ばれる図７に示した整髪具において、１０１は毛髪等を梳く髪梳き部、１０２は取扱いの際に人の手等で保持する握り部である。この従来例では、有機系あるいは無機系の抗菌剤を含む混合物で整髪具を構成し、雑菌の繁殖やカビの発生を抑制している。（例えば、特許文献１参照。）または、抗菌性のゼオライトを利用して整髪具を構成している。（例えば、特許文献２参照）これらの従来例の場合、抗菌材を活用し、雑菌の繁殖やカビの発生を抑制することにおいて効果が期待できるが、整髪具を利用した後に整髪対象の組織あるいは皮脂あるいは整髪剤等の有機物が整髪具へ付着した場合はその付着物は付着したまま残存してしまい、その残存した付着物をコロニーとして雑菌の繁殖やカビの発生等が起こる。
さらには、または「整髪ブラシ」と呼ばれる図８に示した整髪具では、同様に抗菌性のゼオライトを利用して整髪具を構成している。（例えば、特許文献３参照）しかるに、この場合の従来の整髪具においても同様に抗菌材を活用し、雑菌の繁殖やカビの発生を抑制することにおいて効果が期待できるが、整髪具を利用した後に整髪対象の組織あるいは皮脂あるいは整髪剤等の有機物が整髪具へ付着した場合はその付着物は付着したまま残存してしまい、その残存した付着物をコロニーとして雑菌の繁殖やカビの発生等が起こる。以上に様に従来の整髪具においては、自浄作用・抗菌性が不十分であり、使用された整髪具等では整髪対象の組織あるいは皮脂あるいは整髪剤等の整髪具への付着が起こり易く、その付着物は付着したまま残存してしまい、その残存した付着物が雑菌・カビ等の微生物の発生と繁殖を加速することが多く、利用に際して衛生状態が不十分であり、かつ、整髪具から不快な異臭が発生する原因にも成りうるという欠点があった。

【０００４】
【課題を解決するための手段】
上記課題を解決するために本発明では、光に露光されて触媒反応を起こす光触媒としてよく知られている酸化物半導体の二酸化チタンをその構成材料の一部あるいは全部として用い、自浄作用・抗菌性・消臭性を具備する整髪具を構成する。

【発明の実施の形態】
【実施例】
以下に、この発明の実施の形態を図に基づいて説明する。
図１、図２、図３、図４、図５、図６は本発明の整髪具の実施の形態を示す説明図である。図１、図３、図５は本発明の実施例の概観、図２、図４、図６はそれぞれ要部断面構造を明示した説明図である。
図１、図２、図３、図４、図５、図６において、１は毛髪等を梳く髪梳き部、２は取扱いの際に人の手等で保持する握り部、３は表層、４は芯部、５は導光部６は発光体である。
本発明の整髪具においては、図１にある様に、全体外観的には従来の整髪具と同様であるが、図２の要部断面構造（図２は図１中のＡ−Ａ’部の断面構造）を明示した説明図に明示されている様に、本実施例の整髪具の表層３は酸化チタン光触媒が含有されている可塑性樹脂等を用いて構成している。
この二酸化チタンと酸化チタンの混合物あるいは単独組成物からなる酸化チタン光触媒は光があたると、荷電子帯にある電子が、伝導帯に励起され、これにより荷電子帯には正孔が生成し、伝導体には電子が生成する。これらは活性が高く表面では、荷電子帯側では酸化反応が、伝導体側では還元反応が起こる事が知られている。特徴として、酸化チタン光触媒は強い酸化・還元力を持ちいろいろな化合物を酸化・還元する。こうして、酸化チタン光触媒は空気中の酸素や水から活性酸素を生成する。この活性酸素には、その強い酸化力によって、表面に付着した種々の有機物や窒素酸化物等を分解し雑菌を殺し異臭の元となる雑菌を殺すことのみならず、異臭そのものもを分解する作用があることが知られている。この様に酸化チタン光触媒は自浄作用・抗菌性・消臭性を具備する素材として知られている。
図１、図２の本発明の実施例では、可塑性樹脂及び金属等を利用して形成された芯部４の表面に酸化チタン光触媒が含有されている可塑性樹脂か、あるいは酸化チタン光触媒自体を塗布あるいはコーティングなどの手段により表層３として配置している。この際必要に応じて芯部４と表層３の間の密着を良くする手段を用いることが有用であることは言うまでもない。その上、本発明の実施例では芯部４に用いた可塑性樹脂を透明で透光性の素材を用いており、当該の透明で透光性の芯部４が一部表面に露出して酸化チタン光触媒で覆われていない導光部５を構成している。なおかつ、当該の芯部４を構成する可塑性樹脂にはその透光性が損なわれない程度に少なくとも蓄光性の蛍光素材を含み必要に応じてこの蛍光素材の発する光を可視光を含む光に変換して発光する素材等を具備して成る発光体６として混入分散させてある。
ここで、発光体６は必ずしも蓄光性の蛍光素材及びこの蛍光素材の発する光を可視光を含む光に変換して発光する素材等より成るものである必要は無く、豆電球や発光ダイオード等に適切に用意した電池等の電源から必要に応じて電気を供給して必要に応じて発光させるものを発光体６として適切な位置に配置しても良いことは言うまでもない。（例えば導光部５付近に配置して内部に光を照射する仕組みとしても良い）
ところで、本発明の整髪具の全表面に渡って酸化チタン光触媒が含有されている可塑性樹脂により覆うことにより表層３とした場合、酸化チタン光触媒の混合・分散の様子を適切に設定し、それぞれの粒子の隣り合う間隔を適切に設定してやることにより、この際に当該の表層３を構成している可塑性樹脂に透光性の素材を利用すれば、表面に存在する酸化チタン光触媒の粒子と粒子の間隔には光が導入されることは言うまでもなく、これを導光部５とすることも可能である。この表面に存在する酸化チタン光触媒の隣接する粒子の間隔は少なくとも光が通過可能な間隔であれば良く、他の要因も考慮した上で設定すれば良い。この場合の導光部５から導入された光はより内部に光が導入され、より内部において導入された光の一部が内部で反射され本発明の整髪具の表面に戻って表面に存在する酸化チタン光触媒にこの戻って来た光が照射されて光触媒反応を実現できることも言うまでもない。この場合、本発明の整髪具の表層３が十分な厚みに設定されていれば、より内部の芯部４等においては必ずしも透光性が確保されていなくても、表層３内部での反射光による十分な効果があることは言うまでもない。その際には芯部４をより光の反射効率が高い素材であれば何でも良く、例えば白色の可塑性樹脂あるいは金属等の光を反射する素材で構成すると芯部４の表面で反射された光が表面の戻り、表面に存在する酸化チタン光触媒に光りが照射されて十分な光触媒反応が実現できることは言うまでも無い。
さらに必要であるならば、整髪具の全てを透明で透光性の可塑性樹脂を主素材とし、前記発光体６や酸化チタン光触媒が少なくとも含有され混入分散されている素材で一体物として構成することも有用であることは言うまでもない。
また、酸化チタン光触媒が含有される材料を配置する部分としては、整髪具の部分的な表面部位かあるいは整髪具の表面全体に関して実施するかはその必要に応じて行えば良い。図１、図２においては本発明の整髪具（導光部５を除く）のほぼ全ての表面に酸化チタン光触媒かあるいは酸化チタン光触媒を含有した素材を配置した例であるが、必要に応じて利用される状況を考慮して適切な部位の表面に酸化チタン光触媒自体かあるいは少なくとも酸化チタン光触媒を含有した素材を配置することによりそれに応じた効果が得られることは言うまでもない。
さらに、酸化チタン光触媒を含有する表層３を形成するにあたって、型成形によるキャストの方法のみならず、スプレーコートあるいはディピングあるいは蒸着等の各種薄膜形成等の方法が有効であることは言うまでもない。
ところで、本実施例では自浄作用・抗菌性・消臭性を具備し容易に得られる代表例として酸化チタン光触媒を用いたが、本実施例の自浄作用・抗菌性・消臭性を具備する整髪具を構成するにはこれと同様な機能を果たす材料であれば、酸化チタン光触媒に限定されるものでないことは言うまでもない
従来の整髪具においては、使用後に必要があれば洗浄してから保管する際において、残存の汚れ及び不完全な保管状態に起因して雑菌・カビ等の微生物の発生と繁殖が避け難かったが、本発明の実施例においては、光を浴び露光される環境で保管されれば、整髪具の外部からの直接光が本発明の整髪具の表面に配置された酸化チタン光触媒に照射され、あるいは導光部５より外部から導入された光が本発明の整髪具の内部の芯部４に満ち、内部から光が本発明の整髪具の表面に配置された酸化チタン光触媒に照射されることは言うまでもない。その上、一旦こうして光を浴びると本発明の整髪具に具備された蓄光性の蛍光素材及びこの蛍光素材の発する光を可視光を含む光に変換して発光する素材等より成る発光体６で外部からの光が消えた後にも一定の有限の時間のみ追従的に内部からの光が本発明の整髪具の表面に配置された酸化チタン光触媒に照射される。こうして光を浴びた酸化チタン光触媒の自浄作用・抗菌・消臭等の作用により表面に付着した有機物が分解され雑菌・カビ等の微生物を殺すことが可能であり、雑菌・カビ等の発生と繁殖が抑制され、異臭の発生も抑制される。特に、整髪具の髪梳き部１では、人体あるいは動物の毛髪、あるいはその他鬘等の毛髪状構造物等を梳いて使用する際に梳く対象物の組織あるいは皮脂あるいは整髪剤等の各種の付着物が整髪具に付着し残存して放置されることが多い。このとき、これらの各種の付着物がこびり付いた部位でそれをコロニーとして雑菌・カビ等の発生と繁殖が起こりがちであり避けがたい。通常、整髪具は通常は光を浴び露光される環境で使用されるので、本発明の実施例においては酸化チタン光触媒により、表面に付着した主に有機物で構成される梳く対象物の組織あるいは皮脂あるいは整髪剤等の各種の残存した付着物が分解・解消されなおかつ雑菌・カビ等の微生物を殺すことが可能であり雑菌・カビ等の発生と繁殖が抑制される。その上死滅した雑菌・カビ等の死骸も酸化チタン光触媒の作用により分解・解消される。
ところで、残存した付着物が原因で発生する異臭には、雑菌・カビ等が原因となる異臭と、人体あるいは動物の毛髪、あるいはその他鬘等の毛髪状構造物等を梳いて使用する際に梳く対象物の組織あるいは皮脂あるいは整髪剤等の各種の付着物そのものが発する異臭とが考えられる。本実施例の場合有機物や窒素酸化物等に対する効果がある酸化チタン光触媒を用いているので、これらのいずれの異臭そのものをも分解・解消でき、異臭の発生をより効果的に抑制することが可能であることは言うまでもない。
また、取扱いの際に人の手等で握り部２を保持するが、人の手は雑菌が非常に多く、こうして取り扱うだけで、整髪具の握り部２は雑菌等の微生物で汚染される。ところが、本発明の実施例においては、こうして取扱っても使用の合間には通常では光を浴びる環境で使用されるので酸化チタン光触媒により表面に付着した有機物が分解・解消されなおかつ雑菌・カビ等の微生物を殺すことが可能であり雑菌・カビ等の発生と繁殖が抑制され、異臭の発生も抑制される。
図３、図４（図４は図３中のＢ−Ｂ’部の断面構造）も一般に「くし」、「櫛」等と呼ばれる形態の整髪具の例であるが、この場合も同様に光に露光されて触媒反応を起こす光触媒としてよく用いられる酸化物半導体の酸化チタン光触媒をその構成材料の一部あるいは全部としてその表層３等に用い自浄作用・抗菌性・消臭性を具備する整髪具を構成したものであり、上記「くし」、「櫛」、「コーム」等と呼ばれる形態の整髪具と同様な自浄作用・抗菌性・消臭性の機能・効果があることは言うまでもない。
図５、図６（図６は図５中のＣ−Ｃ’部の断面構造）では一般に「整髪ブラシ」と呼ばれる形態の整髪具における本発明の実施例の場合である。この場合も同様に光に露光されて触媒反応を起こす光触媒としてよく用いられる酸化物半導体の酸化チタン光触媒をその構成材料の一部あるいは全部としてその表層３等に用い自浄作用・抗菌性・消臭性を具備する整髪具を構成したものであり、上記「くし」、「櫛」、「コーム」等と呼ばれる形態の整髪具と同様な自浄作用・抗菌性・消臭性の機能・効果があることは言うまでもない。
以上の様に結果として本発明では保管時あるいは利用時に雑菌・カビ等の微生物の発生と繁殖が抑制され、十分良い衛生状態に保たれ、異臭の発生を抑制することが可能である整髪具を提供している。
【０００６】
【発明の効果】
以上の様に、本発明では酸化チタン光触媒をその構成材料の一部あるいは全部として用いて整髪具を構成することにより、当該の整髪具の表面に付着した有機物が分解され雑菌・カビ等の微生物を殺すことが可能であり雑菌・カビ等の発生と繁殖が抑制され、さらには整髪具に付着した付着物をも分解・解消し、その付着物が原因となって発生する異臭を抑制・解消する。
結果として本発明では保管時あるいは利用時に整髪具表面において雑菌・カビ等の微生物の発生と繁殖が抑制され、十分良い衛生状態に保たれ、異臭の発生が抑制されるという効果がある。
なお、本発明では酸化チタン光触媒をその構成材料の一部あるいは全部として用いて整髪具を構成することにより、当該の整髪具の周辺の雰囲気に含まれる異臭をも分解・解消する効果もある。特に、有機物、窒素酸化物のみでなく、硫黄酸化物をも分解することが知られており、これらのものが原因となる異臭を分解・解消する効果も具備していることは言うまでもない。

FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a hairdressing device such as a comb for combing hair and the like and a hairdressing brush.
[0002]
[Prior art]
In the hairdressing tool shown in FIG. 7 called a conventional "comb" or "comb", reference numeral 101 denotes a hair combing portion for combing hair and the like, and reference numeral 102 denotes a grip portion that is held by a hand or the like during handling. In this conventional example, a hairdressing tool is formed of a mixture containing an organic or inorganic antibacterial agent, thereby suppressing propagation of various bacteria and generation of mold. (For example, refer to Patent Document 1.) Alternatively, a hairdressing tool is configured by using an antibacterial zeolite. (For example, see Patent Document 2) In the case of these conventional examples, an effect can be expected in utilizing an antibacterial material to suppress the propagation of various bacteria and the occurrence of mold, but after using a hairdressing tool, the tissue or hair to be trimmed When organic matter such as sebum or a hairdressing agent adheres to the hairdressing device, the attached matter remains as it is, and the remaining attached matter is used as a colony to cause propagation of various bacteria and generation of mold.
Further, in the hairdressing tool shown in FIG. 8 or called a “hairdressing brush”, the hairdressing tool is similarly formed using an antibacterial zeolite. (See, for example, Patent Document 3) In this case, an antibacterial material is similarly used in the conventional hairdressing equipment, and the effect can be expected in suppressing the propagation of various bacteria and the generation of mold. If the tissue to be trimmed or an organic substance such as sebum or a hairdressing agent adheres to the hairdressing device later, the adhered substance remains as it is adhered, and the remaining adhered substance is used as a colony to propagate germs and generate mold. Occur. As described above, in the conventional hairdressing device, the self-cleansing action and antibacterial property are insufficient, and the used hairdressing device or the like easily adheres to the hairdressing device such as the tissue or the sebum or the hairdressing agent of the hairdressing target. The attached matter remains as it is attached, and the remaining attached matter often accelerates the generation and propagation of microorganisms such as bacteria and fungi. There is a drawback that it can be a cause of generating a strange odor.

[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
【Example】
An embodiment of the present invention will be described below with reference to the drawings.
1, 2, 3, 4, 5, and 6 are explanatory views showing an embodiment of the hairdressing tool of the present invention. FIGS. 1, 3, and 5 are schematic views of an embodiment of the present invention, and FIGS. 2, 4, and 6 are explanatory views each clearly illustrating a cross-sectional structure of a main part.
1, 2, 3, 4, 5, and 6, reference numeral 1 denotes a combing portion for combing hair and the like, 2 denotes a grip portion that is held by a hand or the like during handling, 3 denotes a surface layer, Denotes a core, 5 denotes a light guide, and 6 denotes a light emitter.
The overall appearance of the hairdressing device of the present invention is the same as that of the conventional hairdressing device as shown in FIG. 1, but the cross-sectional structure of a main part of FIG. As shown in the explanatory diagram clearly showing the cross-sectional structure of the present invention, the surface layer 3 of the hairdressing tool of this embodiment is made of a plastic resin or the like containing a titanium oxide photocatalyst.
When this titanium oxide photocatalyst consisting of a mixture or a single composition of titanium dioxide and titanium oxide is exposed to light, electrons in the valence band are excited to the conduction band, thereby generating holes in the valence band, Electrons are generated in the conductor. It is known that these have high activity, and on the surface, an oxidation reaction occurs on the valence band side and a reduction reaction occurs on the conductor side. Characteristically, titanium oxide photocatalyst has strong oxidizing and reducing power and oxidizes and reduces various compounds. Thus, the titanium oxide photocatalyst generates active oxygen from oxygen and water in the air. Due to its strong oxidizing power, this active oxygen not only decomposes various organic substances and nitrogen oxides attached to the surface, kills various bacteria and kills various germs that cause an unpleasant odor, but also decomposes the unpleasant odor itself. It is known that there is. As described above, the titanium oxide photocatalyst is known as a material having a self-cleaning action, an antibacterial property, and a deodorant property.
In the embodiment of the present invention shown in FIGS. 1 and 2, a plastic resin containing a titanium oxide photocatalyst or a titanium oxide photocatalyst itself is applied to the surface of a core portion 4 formed by using a plastic resin and a metal. Alternatively, it is arranged as the surface layer 3 by means such as coating. At this time, it is needless to say that it is useful to use a means for improving the adhesion between the core portion 4 and the surface layer 3 if necessary. In addition, in the embodiment of the present invention, the plastic resin used for the core 4 is made of a transparent and translucent material, and the transparent and translucent core 4 is partially exposed on the surface and oxidized. The light guide 5 is not covered with the titanium photocatalyst. In addition, the plastic resin constituting the core portion 4 contains at least a phosphorescent fluorescent material to such an extent that the translucency is not impaired, and converts light emitted from the fluorescent material into light containing visible light as necessary. It is mixed and dispersed as a luminous body 6 comprising a material or the like which emits light.
Here, the luminous body 6 does not necessarily need to be made of a phosphorescent fluorescent material and a material that converts light emitted by the fluorescent material into light including visible light and emits light. It is needless to say that a device that supplies electricity as needed from a power source such as an appropriately prepared battery and emits light as needed may be arranged at an appropriate position as the light emitter 6. (For example, it may be arranged near the light guide unit 5 to irradiate light inside).
By the way, when the surface layer 3 is formed by covering the entire surface of the hairdressing tool of the present invention with a plastic resin containing a titanium oxide photocatalyst, the state of mixing and dispersion of the titanium oxide photocatalyst is appropriately set, and By appropriately setting the interval between adjacent particles, if a translucent material is used for the plastic resin constituting the surface layer 3 at this time, the particles of the titanium oxide photocatalyst existing on the surface and the particles It goes without saying that light is introduced into the space, and this can be used as the light guide section 5. The interval between adjacent particles of the titanium oxide photocatalyst existing on the surface may be at least an interval through which light can pass, and may be set in consideration of other factors. In this case, the light introduced from the light guide unit 5 is further introduced into the inside, and a part of the light introduced inside is reflected inside and returns to the surface of the hairdressing tool of the present invention and exists on the surface. It goes without saying that a photocatalytic reaction can be realized by irradiating the returned light to the titanium oxide photocatalyst. In this case, if the surface layer 3 of the hairdressing device of the present invention is set to a sufficient thickness, the reflected light within the surface layer 3 can be obtained even if the inner core portion 4 or the like does not necessarily have light transmission. Needless to say, there is a sufficient effect. In this case, any material may be used as long as the core portion 4 has a higher light reflection efficiency. For example, if the core portion 4 is made of a material that reflects light, such as a white plastic resin or a metal, the light reflected on the surface of the core portion 4 can be formed. It goes without saying that the surface is returned and the titanium oxide photocatalyst existing on the surface is irradiated with light to realize a sufficient photocatalytic reaction.
Further, if necessary, all the hairdressing tools are made of a transparent and translucent plastic resin as a main material, and the luminous body 6 and the titanium oxide photocatalyst are at least contained and mixed and dispersed as a single material. Needless to say, it is also useful.
Whether to implement the material containing the titanium oxide photocatalyst on a partial surface portion of the hairdressing tool or on the entire surface of the hairdressing tool may be determined as necessary. FIGS. 1 and 2 show examples in which a titanium oxide photocatalyst or a material containing a titanium oxide photocatalyst is arranged on almost all surfaces of the hairdressing tool (except for the light guide section 5) of the present invention. It is needless to say that the titanium oxide photocatalyst itself or the material containing at least the titanium oxide photocatalyst is arranged on the surface of an appropriate portion in consideration of the situation in which the photocatalyst is used.
Furthermore, in forming the surface layer 3 containing the titanium oxide photocatalyst, it goes without saying that not only a casting method by molding, but also a method of forming various thin films such as spray coating, dipping or vapor deposition is effective.
By the way, in the present embodiment, a titanium oxide photocatalyst is used as a representative example having self-cleaning action, antibacterial property and deodorant property and easily obtained, but hair styling having self-cleaning action, antibacterial property and deodorant property of this embodiment is used. It is needless to say that titanium oxide photocatalyst is not limited to titanium oxide photocatalyst as long as it is a material that fulfills the same function to construct the tool. In this case, it was difficult to avoid the occurrence and propagation of microorganisms such as germs and molds due to residual dirt and incomplete storage conditions.However, in the embodiment of the present invention, the microorganisms are stored in an environment exposed to light and exposed to light. If this is the case, direct light from the outside of the hairdressing tool is applied to the titanium oxide photocatalyst disposed on the surface of the hairdressing tool of the present invention, or light introduced from the outside through the light guide 5 is applied to the inside of the hairdressing tool of the present invention. Filled with core 4 inside It goes without saying that Luo light is irradiated to the titanium oxide photocatalyst disposed on the surface of the hair styling device of the present invention. In addition, once exposed to light, the luminous body 6 made of a phosphorescent fluorescent material provided in the hairdressing device of the present invention and a material that converts light emitted from the fluorescent material into light containing visible light and emits light. Even after the light from the outside disappears, the light from the inside is irradiated on the titanium oxide photocatalyst arranged on the surface of the hairdressing tool of the present invention in a following manner only for a certain finite time. In this way, the organic matter attached to the surface is decomposed by the action of self-cleaning action, antibacterial action, deodorizing action, etc. of the titanium oxide photocatalyst exposed to light, and it is possible to kill microorganisms such as germs and molds, and the occurrence and propagation of germs and molds Is suppressed, and generation of an unusual odor is also suppressed. In particular, in the combing section 1 of the hairdressing tool, when combing and using human or animal hair, or other hair-like structures such as wigs, the tissue of the object to be combed or various kinds of deposits such as sebum or a hairdressing agent. Often adhere to the hairdressing tool and remain as it is. At this time, it is difficult to avoid the occurrence and propagation of various bacteria and fungi as colonies at the site where these various attachments are stuck. Usually, hairdressing tools are used in an environment exposed to light and exposed to light. Therefore, in the embodiment of the present invention, the tissue or sebum of an object to be combed mainly composed of organic substances adhered to the surface by the titanium oxide photocatalyst. Alternatively, various remaining deposits such as hair styling agents can be decomposed and eliminated, and microorganisms such as bacteria and mold can be killed, so that the generation and propagation of bacteria and mold can be suppressed. In addition, dead dead bacteria and molds are decomposed and eliminated by the action of the titanium oxide photocatalyst.
By the way, the unpleasant odors caused by the remaining deposits include the unpleasant odors caused by germs and mold, and the hair of a human body or an animal, or other hair-like structures such as wigs. It is considered that the odor is emitted from the tissues of the object or various kinds of attached substances such as sebum or a hairdressing agent. In the case of this embodiment, since a titanium oxide photocatalyst having an effect on organic substances, nitrogen oxides, and the like is used, any of these off-odors can be decomposed and eliminated, and the generation of off-odors can be more effectively suppressed. Needless to say,
In addition, the grip portion 2 is held by a human hand or the like at the time of handling. However, the human hand has a large amount of various germs, and the grip portion 2 of the hair styling tool is contaminated with microorganisms such as various germs only by handling in this manner. However, in the embodiment of the present invention, the organic matter attached to the surface is decomposed and eliminated by the titanium oxide photocatalyst, and the bacteria, mold, etc. are still used during the use even in this manner, since it is usually used in an environment exposed to light. Microorganisms can be killed, and the occurrence and propagation of various bacteria and molds are suppressed, and the generation of off-flavors is also suppressed.
FIGS. 3 and 4 (FIG. 4 is a cross-sectional structure taken along the line BB 'in FIG. 3) are examples of hairdressing tools generally referred to as "combs" and "combs". Hairdressing device having self-cleaning action, antibacterial property, and deodorant property, using titanium oxide photocatalyst of oxide semiconductor, which is often used as a photocatalyst to cause a catalytic reaction when exposed to light, as part or all of its constituent material for surface layer 3 and the like It goes without saying that it has the same self-cleaning action, antibacterial property and deodorant function and effect as those of the hairdressing tools in the form called "comb", "comb", "comb" or the like.
FIGS. 5 and 6 (FIG. 6 is a cross-sectional structure taken along the line CC ′ in FIG. 5) show an embodiment of the present invention in a hairdressing device having a form generally called a “hairdressing brush”.
