DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, reference numeral 1 denotes a whistle (whistle) used by a referee in a sports competition, for example.
A mouthpiece 3 having an air supply port 2 to be put into the mouth of a judge, i.e., a user of the whistle, and to which air is sent; a resonance chamber 4 for generating a whistle sound by the sent air; Exhaust port 5 provided in the Reference numeral 6 denotes a whistle ball stored in the resonance chamber 4. The whistle 1 is made of resin such as AB
The mouthpiece 3 and the resonance chamber 4 are integrally formed of the S resin. An antimicrobial material is mixed and dispersed in this resin at the time of molding. That is, when mixing the antibacterial material into the resin, the antibacterial material is first uniformly mixed with a tumbler, and then pelletized with a pelletizer. Thereafter, the pellets are molded by a usual injection molding method or the like. For example, the whistle 1 is formed by being divided into two parts as shown by a broken line B in FIG.
That is, in the whistle 1, the antibacterial material is dispersed throughout. The whistle ball 6 is also made of ABS resin mixed with the above antibacterial material. This is because saliva also easily adheres to the whistle ball 6.

In order for fungi to propagate, a breeding source is required on a regular basis. In the whistle described above, saliva is scattered at the time of blowing and adheres to the mouthpiece portion 3 and the portion of the resonance chamber 4 where air comes into contact. Normally, there are many fungi in saliva, which propagate using the saliva attached to the mouthpiece 3 and the resonance chamber 4 as a nutrient source.

As the antibacterial material, an inorganic antibacterial material, for example, an antibacterial material in which minus silver ion (silver complex salt) is supported on porous silica gel can be used. This antibacterial material is obtained by complexing silver with thiosulfatosilver, reacting it in an aqueous solution, incorporating it into the pores of silica gel particles, and further coating the surface with silica gel to give a sustained release to silver ions. Polypropylene resin, polyvinyl chloride resin, acrylonitrile butadiene (AB
S) It can be mixed into a molded article such as a resin, an unsaturated polyester resin or a reactive cured resin. An antibacterial material having such a structure is commercially available under the trade name “Amenitop” (manufactured by Matsushita Electric Industrial Co., Ltd.), and exhibits an antibacterial effect at an addition rate of about 1%. Further, since silica gel is a transparent body, there is no possibility of affecting the color of the resin molded product.

The above-mentioned silver silica gel antibacterial material has a function of causing oxygen in the air and water to become active oxygen by the catalytic action of silver ions, thereby damaging the cell surface (oligodynamic action), or incorporating silver ions into the cells. The antibacterial effect of silver, which is said to cause oxygen damage, inhibits the growth of fungi. This antibacterial material is excellent in safety and has an antibacterial effect against Escherichia coli, staphylococci, Pseudomonas aeruginosa and the like for a long period of time.

As the antibacterial material, in addition to the above materials, organic nitrogen,
Organic antibacterial material using organic arsenic and organic chlorine, silver zeolite antibacterial material carrying silver's antibacterial effect on zeolite, silver glass based antibacterial performance by incorporating silver in the matrix of water-soluble glass Antibacterial materials, nitrile derivatives, imidazole derivatives, tribuudine derivatives, sulfone derivatives, phenol ether derivatives and the like can be used.

In the whistle 1 having the above-described structure, an antibacterial material can be applied to the surfaces of the mouthpiece 3 and the resonance chamber 4 so that antibacterial properties can be imparted thereto. When the whistle 1 is made of metal, it is easier to impart antibacterial performance by coating.

FIG. 3 shows a mouthpiece 7 of a wind instrument such as a clarinet or a saxophone.
A flaky vibrating lead 9 is usually attached to this by a cord-like lead holder 8. Mouthpiece part 7
Is formed of a resin, and the above-described antibacterial material is mixed therein during the molding. In the case of such a wind instrument, on the side of the resonance chamber, only a portion where the sent air comes into contact can be made of a resin mixed with an antibacterial material. Further, a structure in which an antibacterial material is applied to the resin surface may be employed. When the mouthpiece 7 is formed of metal, the antibacterial material is applied to the surface.

[0017]

According to the present invention, an antibacterial property is imparted by mixing or coating an antibacterial material into a mouthpiece part such as a whistle or a wind instrument and a constituent part of the resonance chamber where saliva may adhere. Even in an environment where fungi can easily propagate due to the adhesion of saliva, etc., this can be suppressed, and the generation of odor caused by fungi can be prevented, and a clean and safe sounding device for the human body can be realized. Can be.

Further, according to the present invention, by using a silver silica gel-based antibacterial material as an antibacterial material, high antibacterial performance can be stably maintained for a long period of time while ensuring safety against the human body.
