The container body 2 is formed by dispersing the copper fine particles 30 in the resin 4 . Specifically, the container body 2 is formed by mixing a large number of fine copper particles 30 and the resin 4, adding an appropriate coupling material such as a sealant coupling material, and other additives as necessary, and injection molding. As for the resin which comprises the container main body 2, resin which has light transmittance is preferable. As the kind of resin, for example, polyolefin resins such as polypropylene, polystyrene-based, and polyester-based resins can be used. Copper is an example of the first metal. In addition, as the first metal, it is sufficient if it is a metal having an effect of reducing bacteria, and not only copper but also silver or zinc, for example. In this specification, "copper" shall include copper and copper oxide. The resin 4 is an example of the first resin.

The size of the fine particles 30 is defined to be sufficiently smaller than the thickness W1 of the wall of the container body 2 . As the size of the fine particles 30 , for example, the maximum value d50 of the particle size distribution of the fine particles 30 is used.

The suction tube 6 is made of a member containing titanium dioxide (TiO2). Specifically, the suction tube 6 is extruded by mixing a large number of titanium dioxide fine particles 40 and resin 8, adding an appropriate coupling material such as a sealant coupling material, and other additives as needed. is formed The resin constituting the suction tube 6 is a resin having light transmittance after molding. Resins, such as soft polyethylene, soft polypropylene, soft polyurethane, soft silicone, soft polyether ether ketone, and soft vinyl chloride, can be employ|adopted as the kind, for example.

In addition, the second metal may be a metal that generates hydrogen ions in water by contacting water directly or through the resin 8 without using electrolysis using an external power source such as a battery, and is not limited to titanium dioxide . Moreover, the 2nd metal is a metal functioning as a photocatalyst. The metal functioning as a photocatalyst is not limited to titanium dioxide, For example, tungsten oxide may be used. When titanium dioxide, which is the second metal, receives light, electrons are generated, and hydrogen ions can be generated in the water stored in the container body 2 . The resin 8 is an example of the second resin.

The size of the fine particles 40 is defined to be sufficiently smaller than the wall thickness W2 of the suction tube 6 . The method for specifying the size of the fine particles 40 is the same as the method for specifying the size of the fine particles 30 described above.

A process of generating copper ionized water without using electrolysis using an external power source by storing water in the container body 2 will be conceptually described with reference to FIGS. 6 to 8 . Description of the chemical reaction formula will be omitted. 6 to 8 , description of the pump member 10 is omitted, and the container body 2 and the suction tube 6 are shown.

As shown in FIG. 6 , when water 60 is stored in the container body 2 , the water 60 comes into contact with the suction tube 6 . In this state, when light (ultraviolet rays) hits the titanium dioxide fine particles 40 forming the suction tube 6, electrons e are generated from the titanium dioxide. Subsequently, as shown in FIG. 7 , hydrogen ions H+ are generated from water 60 by the action of electrons e. Then, as shown in FIG. 8, elution of copper ion Cu2+ from the copper fine particle 30 which forms the container main body 2 is accelerated|stimulated by hydrogen ion H+. Thereby, the water 60 becomes the copper ion water 62 containing copper ions. In this way, just by pouring water into the container body 2, copper ionized water is easily produced without using electrolysis using an external power source. The above phenomenon was confirmed by experiments by the inventors of the present invention.

When the inventor of the present invention puts water into the container body 2 and puts the suction tube 6 formed of a resin containing titanium dioxide, compared with the case where only water is put into the container body 2, the amount of copper ion elution This significant increase was confirmed. Fig. 9 shows a case where only water is put without placing the suction tube 6 in the container body 2, and a case where water is placed with the suction tube 6 in the container body (hereinafter, "this It is called embodiment".), the contrast of the generation|occurrence|production situation of copper ions is shown. The weight ratio of titanium dioxide in the suction tube 6 is 60% by weight. The weight ratio of the copper fine particles 30 in the container body 2 is 60% by weight. 9 : shows the transition of copper ion concentration every 24 hours at room temperature.

As shown in Fig. 9, when only water is put in the container body 2, the elution degree of copper ions is low, and when 120 days have elapsed, it is less than 20 ppm. On the other hand, in the case of this embodiment, it exceeds 30 ppm at the time of ten days lapse. In this way, the elution of copper ions from the container body 2 is greatly accelerated by the action of the suction tube 6 . Further, unlike this embodiment, in the suction tube 6 , at least some of the fine particles 40 among the large number of fine particles 40 are not covered by the resin 8 , but are exposed from the resin 8 . , electrons can be generated from titanium dioxide more effectively. Further, unlike this embodiment, the container body 2 is placed in an upper portion (for example, a quarter of an upper portion that can be placed in the vertical direction) and a lower portion (for example, three quarters of a lower portion that can be placed in the vertical direction). ), and the upper part is composed of a light transmitting part (light introducing part) excellent in light transmittance without mixing the microparticles 30 into the resin having light transmittance, and the lower part is mixing the microparticles 30 as in this embodiment Configuration is also possible.

10 is a diagram showing an example of use of the container 100 . For example, a doormat 202 is disposed at the entrance and exit of the house 200 . The mother 204 sprays the copper ionized water 62 produced by the container 100 on the doormat 202 to soak it. When a child 206 or dog 208 returning from going out steps on the doormat 202 before entering the house 200 and passes through it, the copper ions contained in the copper ion water 62 permeated into the doormat 202 is removed. By this effect, it is possible to reduce bacteria adhering to the bottom of the shoe of the child 206 or the leg of the dog.

<Second embodiment>

Next, with reference to FIG. 11 and FIG. 12, 2nd Embodiment is demonstrated. Matters in common with the first embodiment will not be described, and will be mainly described with respect to other parts.

As shown in FIG. 11 , the container body 2A of the second embodiment is formed by dispersing the copper fine particles 30 and the ceramic fine particles 50 in the resin 4 . The ceramic is, for example, alumina or silicon carbide (SiC). Moreover, as for a ceramic, a porous ceramic is preferable.

In the case of dispersing the copper fine particles 30 and the ceramic fine particles 50 in the resin 4 in the container body 2A (hereinafter referred to as “configuration 2”), the composition (hereinafter referred to as “configuration 2”) is, in weight ratio, copper fine particles:ceramic fine particles: Resin = 10:50:40. That is, the configuration 2 is a configuration in which a part of the resin in the configuration 1 is replaced with ceramic fine particles. At 10 days, for configuration 1, copper ions were 2.5 ppm or less. In contrast, in the case of configuration 2, after 10 days, it was about 9.0 ppm. Therefore, even if the weight of the copper fine particles 30 in the container body 2A does not change, it turns out that the elution of copper ions is greatly accelerated by adding the ceramic fine particles 50 .

By dispersing the copper fine particles 30 and the ceramic fine particles 50 in the resin 4 , one of the reasons that the elution of copper ions is greatly accelerated is that the ceramic fine particles 50 rather than the resistance of copper ions pass through the resin 4 . ) or the resistance passing through the surface of the ceramic fine particles 50 is considered to be smaller.
