The present invention relates to dishes such as plates, cups, mugs, pots, chopsticks, and cutting boards, musical instruments such as harmonica, whistle, and trumpet, as well as a microphone mouthpiece. In particular, the present invention relates to tableware and musical instruments having properties such as antibacterial properties, malodor decomposition properties, and antiallergic properties. In addition, cooking utensils such as a pot and a cutting board are collectively referred to as tableware in the present specification.

る。The proliferation of bacteria on the surfaces of tableware and cooking utensils may be a problem. For example, staphylococci, salmonella, etc. may grow on the surface of the cutting board, the fresh food cooked on the staphylococcus may attach to the bacteria, and the bacteria may grow in the food to cause food poisoning. Even if it does not reach to that point, the proliferation of various bacteria may make the tableware odorous and the food muzzle. In order to prevent such a situation, an antibacterial cutting board made by kneading and molding an antibacterial agent such as silver, copper or zinc into hard plastic is sold.

起こりやすい。Such bacterial propagation can also occur on the surfaces of metal spoons, forks, plates, cups and the like. There is no problem of bacterial growth if the dishes are sterilized with hot water every time they are used. However, doing so each time is labor-intensive and energy-intensive and unrealistic. Further, in the homes of disabled persons, the elderly and students, dishwashing may be incomplete. In that case, bacterial propagation on the surface of the tableware is likely to occur.

Often, the saliva in the mouth and breath adheres to these musical instruments and the like, bacteria are propagated, and a bad odor is generated. By the way, recently, metal allergy associated with the use of jewelry such as earrings has become a problem. Metal allergies can cause itching, irritation, or blistering on the skin where the metal touches the skin. The mechanism of metal allergy is that the metal dissolves and ionizes and binds to the protein in the skin, and the skin protein causes a rejection reaction to the metal-plated epidermal protein while it is repeated many times. It is said that it causes dermatitis.

ある。Metals that are prone to metal allergies are said to be mercury, nickel, cobalt, tin, chromium and copper. It has also been reported that noble metals such as platinum and gold that are difficult to ionize may cause metal allergies. Moreover, even if a metal allergic person understands the metal causing the allergy of his / her own, due to the similarity of the atomic structure, the person having Ni as the cause is Co and Au.
It is said that there is a cross-reaction that occurs not only with one causative metal but also with other metal ions. It is extremely difficult to select and judge accessories materials.

There is also the risk of other infectious diseases.

こともない。When titanium oxide receives ultraviolet rays (which may be the light of a fluorescent lamp), electrons (-) and holes (+) are generated, and the generated holes convert oxygen on the surface of dishes such as active oxygen (OH). Radical). This active oxygen decomposes many chemical substances that are said to be difficult to decompose into hydrogen and carbon dioxide. In the process, sterilization and decomposition of malodorous components occur. Further, since the titanium anodic oxide layer is an extremely stable material layer, it is hardly ionized. Therefore, bacteria on the surface of the tableware are sterilized, and metal allergy associated with contact between the skin and the tableware does not occur.
