繁殖することがあった。However, after storing the dishes in the dish dryer,
It takes a long time to completely dry not only the tableware but also the tableware container of the tableware dryer, and sometimes the power is cut off by a timer or the convenience of the user before the tableware is sufficiently dried. When such imperfect drying is repeated several times, germs may sometimes propagate in portions of the dish dryer where heat conduction is poor.

するものが多いため、長期間にわたり抗菌性を保持する
ことは困難であった。また、その安全性に疑問のある素
材も多かった。In such a conventional dish dryer, attempts have been made to add an antimicrobial agent to the resin used in the food container in order to prevent the propagation of various bacteria. Of the antibacterial agents, most of the organic antibacterial agents exert antibacterial effects by air diffusion, and thus it was difficult to maintain the antibacterial properties for a long period of time. There were also many materials whose safety was questionable.

の問題があった。Among inorganic antibacterial agents, silver antibacterial agents have recently attracted attention as highly safe antibacterial agents. But,
Silver-based antibacterial agents react with chlorine-based chemicals or decompose with ultraviolet light and lack light resistance, which makes them difficult to use in chlorine-based bleaching agents and dishware containers that can be disinfected by sunlight. .

菌剤を成形用樹脂に添加混合し、樹脂で食器収納容器本
体を成形するようにしたものである。According to the present invention, an antibacterial agent mainly composed of silver, silver ions or a silver complex salt is added to a molding resin and mixed to form a tableware container main body with the resin. It is something to do.

より表面の清浄度が低下する。Conventionally, tableware is directly in contact with the surface of the tableware container, so that nutritive organic substances attached to the tableware adhere to the surface of the tableware container. The concentration of bacteria itself in tableware or tap water is low and is not a problem,
Proliferation on the tableware container along with other airborne bacteria reduces the cleanliness of the surface.

表面の清浄度を向上させる作用を有するものである。According to the structure of the present invention, the antibacterial agent is added to the tableware container to impart cleansing effect to the surface of the tableware container.

銀系抗菌剤を用いた。[0013] Antibacterial agents for tableware dryers have a high possibility of coming into direct contact with tableware. Therefore, even if they enter the human body through the tableware, they are kept safe for the human body. The antibacterial agent was mixed in the wastewater because of the purification treatment, and a silver-based antibacterial agent was used as a safe antibacterial agent having a low vapor pressure to prevent the purification of the wastewater from being hindered.

器の着色を抑制するのに最も効果的であった。However, since silver-based antibacterial agents release silver salts slowly, a coloring reaction occurs in the presence of chlorine and light. For cleaning dishes and tableware storage containers, chlorine-based liquid cleaning chemicals such as bleaching detergents containing sodium hypochlorite are commonly used.
A silver thiosulfato complex salt stable to photoreaction was used. Further, after the silver thiosulfato complex salt is supported on the silica gel, a part of or the entire surface is coated with a coating material such as tetraethoxysilane or tetramethoxysilane, thereby using a silver-based antibacterial agent to color the tableware container. Was most effective in controlling
