The tablets of the present invention that generate chlorine dioxide by reaction with water contain metal chlorite, organic acids, carbonates, polyethylene glycol, neutral anhydrous bladder and talc. Next, each component will be described.

[Metallic chlorite]
The metal chlorite that can be used in the tablet of the present invention is not particularly limited as long as it can be a source of chlorine dioxide. For example, general chlorite alkali metal salts such as sodium chlorite and potassium chlorite, and general chlorite alkaline earth metal salts such as magnesium chlorate and calcium chlorite can be used. Sodium chlorite is most preferable from the viewpoint of economy and practicality. Further, the metal chlorite can be contained not only in one type but also in a combination of a plurality of types in the tablet.

The amount of metal chlorite in the tablet is preferably 0.1 to 10% by weight based on the whole tablet. A metal chlorite in this range can generate a practical amount of chlorine dioxide from the viewpoint of sterilization and the like.

[Organic acid]
The organic acid that can be used in the tablet of the present invention is not particularly limited as long as it functions to generate chlorine dioxide together with the above metal chlorite. For example, succinic acid, citric acid, fumaric acid, adipic acid, and the like can be used. However, organic acids with a very low pH are not suitable from the viewpoint of tableting.

The amount of organic acid in the tablet is preferably 10 to 40% by weight based on the whole tablet. An organic acid in this range can generate a practical amount of chlorine dioxide from the viewpoint of sterilization and the like.

[Carbonate]
The carbonate that can be used in the tablet of the present invention is any as long as it acts as an alkaline agent to react with a part of the above organic acid to generate carbon dioxide to help water permeate into the tablet. , Is not particularly limited. For example, sodium carbonate, sodium hydrogen carbonate, or the like can be used. Further, the carbonate may be contained not only in one type but also in a combination of a plurality of types in the tablet.

The amount of carbonate in the tablet is preferably 1 to 5% by weight based on the whole tablet. Carbonates in this range are practical from the viewpoint of the effect of promoting the penetration of water into tablets.

[Polyethylene glycol]
Polyethylene glycol acts as a binder during tablet compression and improves releasability from the tablet device.

The amount of polyethylene glycol in the tablet is preferably 15 to 25% by weight based on the whole tablet. Polyethylene glycol in this range is practical from the viewpoint of bondability and releasability during tablet compression.

[Neutral anhydrous broom]
By using neutral anhydrous bladder, it is possible to realize a tablet that maintains a positional relationship in which the three components of metal chlorite, organic acid, and carbonate do not become too close. By maintaining the positional relationship in which the above three components do not become too close, it is possible to prevent tableting problems, and it is also possible to prevent chlorine dioxide from being generated all at once when water is added to the tablets. It is also effective in improving the sustainability of chlorine dioxide generation.

The amount of neutral anhydrous bladder in the tablet is preferably 20 to 71% by weight based on the whole tablet. If it is a neutral anhydrous bladder in this range, it is possible to prevent a tableting disorder and improve the sustainability of chlorine dioxide generation.

[talc]
Talc is a lubricant / mold release agent that smoothes the production of tablets by preventing the powder, which is a tablet component, from adhering to the tablet device.

The amount of talc in the tablet is preferably about 1% by weight based on the whole tablet. Talc in this range is excellent from the viewpoint of lubricant and mold release agent.

[Moisture content]
The moisture contained in the tablets of the present invention can produce chlorine dioxide before use. Therefore, if the water content in the tablet is high, the amount of chlorine dioxide generated during actual use will be small. That is, the water content of the tablet has a great influence on the ability to produce chlorine dioxide. Therefore, the smaller the water content in the tablet, the better.

[Tablet manufacturing method]
As a method for producing a tablet of the present invention, for example, metal chlorite, an organic acid and a carbonate are individually dried, each component is mixed, and polyethylene glycol, neutral anhydrous bladder and talc are further added. Then, the tablet may be obtained by putting it in a normal tableting machine and applying pressure to perform the tableting process. In addition, the obtained tablets may be subjected to a general drying step if necessary.

[Container for holding tablets]
Next, the housing 1 of the portable chlorine dioxide generating tool of the present invention will be described. As shown in FIGS. 1 and 2, two quadrilateral (length: about 8 cm, width: about 10 cm) sheets 1A and 1B are stacked, tablets are stored in the gaps thereof, and peripheral portions 11 and 12 of the stacked sheets are stacked. , 13, 14 are joined to form a bag-shaped container 1. As the property of the sheet, it is sufficient that it does not corrode to chlorine dioxide, and for example, a laminate of aluminum and plastic can be used.

A cutout hole 2 for attaching a locking tool is formed in the central portion of the upper end of the housing. Small holes 3 penetrating between the outside and the inside of the housing are formed on the front surface surface of the housing, and a horizontal row or the like is formed from one side edge to the other side edge at a position closer to the upper part of the housing 1. It is arranged at intervals, and small holes 3 are arranged on the left and right with a central portion opened in a horizontal row at a position closer to the lower part of the housing.

[Example of using portable chlorine dioxide generator]

When water is added to the tablet through the small holes 3 with a dropper or the like, the following chemical reaction occurs and chlorine dioxide is generated. Further, by adjusting the amount of water added to the tablet, the strength of the amount of chlorine dioxide released and the generation time can be controlled.
15NaClO ₂ + 4HO ₂ CC (OH) (CH ₂ CO ₂ H) ₂ → 12ClO ₂ + 4C ₆ H5Na ₃ O ₇ + 3 NaCl + 2H ₂ O

A neck strap or the like can be attached to the housing body 1 and can be hung from the neck. By adding water to the tablet and hanging the container 1 in which chlorine dioxide is released from the small holes 3 from the neck, chlorine dioxide is mixed with the air around the face and the air around the face is removed. Can be fungus. Therefore, it is possible to prevent bacteria and the like from invading from the respiratory organs.

In addition, the results in Table 4 show that it has a particularly beneficial effect in the deodorizing / deodorizing performance test for trimethylamine.

[Measurement of chlorine dioxide gas concentration]
Measurement sample: Chlorite-containing tablet Measuring method: Drop a drop of water on the tablet, enclose it in a plastic bag of about 7 liters, and measure the concentration with a gas detection tube after 20 minutes. The sample after the measurement is left in an open state, and the same test is performed after a certain number of days have passed.

From the results in Table 5, the tablet of the present invention stably generates chlorine dioxide having a sterilizing, deodorizing, and deodorizing effect (see above) for 45 days with each drop of water. It has been shown.

As described above, according to the present invention, it is possible to release chlorine dioxide by adjusting the amount of release. Therefore, in a closed place where wind is unlikely to occur, the released chlorine dioxide tends to stay around the user's body, and the air around the user can be effectively sterilized. Therefore, when people are congested and in close contact with each other in a closed place, that is, when they are concerned about the three-congested state, the portable chlorine dioxide generating tool of the present invention should be used to sterilize the air around the user. Therefore, the risk of the three-csight state can be reduced. When the portable chlorine dioxide generating tool of the present invention is used outdoors where the wind flows, a part of the released chlorine dioxide is washed away by the wind. Therefore, the effect of sterilizing the air around the user is slightly weakened, but the stable generation of chlorine dioxide continues, so that the effect can be maintained to a certain extent.
