Description

The present invention relates to a method for distributing a bactericide containing hypochlorous acid as a main bactericidal chemical species.

There are bactericides filled in containers for distribution and sale. For example, iodine agent, ethanol, hydrogen peroxide solution, inverse soap, phenols, mercurochrome liquid and the like. They are all chemically stable. On the other hand, those with low stability, such as sodium hypochlorite, are distributed in a chemically stabilized manner such as high concentration or strong alkalinization in order to compensate for it. On the other hand, there are almost no examples in which containers with relatively low stability are filled in containers and distributed and sold in a ready-to-use state. This is because it was difficult to maintain the efficacy for a long time.

By the way, in recent years, solutions containing hypochlorous acid prepared by electrolyzing dilute hydrochloric acid or dilute saline solution have been designated as food additives because they are highly safe and have little impact on the target. It has begun to be used as a disinfectant that can be used for various purposes. They are collectively referred to as electrolyzed water and are bactericides that use hypochlorous acid as the main bactericidal chemical species. Among them, slightly acidic electrolyzed water prepared by electrolyzing dilute hydrochloric acid in a non-diaphragm electrolytic cell and mixed and diluted with water, and strongly acidic electrolyzed water obtained from the anode chamber by electrolyzing a dilute solution of sodium chloride in a diaphragm type electrolytic cell There is. Of these, slightly acidic electrolyzed water can be produced in large quantities and is more stable than strongly acidic electrolyzed water, so it is expected to be widely used in industry and households.

As described above, these electrolyzed waters have almost no influence on the object, the environment, and humans, and have almost no taste, color, or smell. No toxicity has been observed in safety tests conducted with animals and microorganisms. Furthermore, even if it is used in foods, it does not affect the taste, texture, or nutritional components. Above all, slightly acidic electrolyzed water does not cause rough skin even if it is touched by humans, and no harm is observed even when sprayed. Even when food is sterilized, it does not produce trihalomethane, has a strange odor, or deteriorates the texture like conventional sodium hypochlorite solution. In addition, even if the waste liquid flows as it is to the treatment site with microorganisms, the microorganisms are not adversely affected. In spite of being extremely excellent in safety and harmlessness as described above, it exhibits a quick bactericidal effect on most microorganisms, so that the usability is extremely excellent. Therefore, applications with few restrictions are expected in a wide range of use fields that are completely different from the concept of conventional bactericides.

By the way, recently, as a similar product of the slightly acidic electrolyzed water described above, a product in which hypochlorite is neutralized with an acid and the liquidity is adjusted to the pH of the slightly acidic electrolyzed water has begun to be used. This water also has a sterilizing component of hypochlorous acid and has similar properties to electrolyzed water, so it can be considered as one of the sterilizing agents using hypochlorous acid as the main sterilizing chemical species.

However, the only drawback of these disinfectants containing hypochlorous acid as the main disinfectant chemical species is their low stability, and as a result, there was no distribution in the disinfectant state. Since the only distribution means was the distribution sale of the generators, its diffusion was slow despite its excellent properties.

The trial of the distribution | circulation as a disinfectant seen slightly is shown to patent document 1. FIG. This was previously invented by the inventors. Disclosed is electrolyzed water filled in laminate containers and PET bottles.

JP 2004-182298 A

Conventional disinfectants have a lot of drawbacks such as toxic strength, persistence, high price, strong influence on the target and surroundings, apart from bactericidal effect, many restrictions on use and safe use for a wide range of applications There was nothing I could do.

On the other hand, bactericides developed in recent years and using hypochlorous acid as the main bactericidal chemical species, such as slightly acidic electrolyzed water, which are gradually spreading, have almost no shortcomings seen in conventional bactericides and are limited in use. Since there is almost no, it can be used safely in a wide range of applications. However, since the stability is low, the water itself has not been circulated so far, and the user purchases a generation device, generates it for use individually, and uses it. For this reason, improper adjustment or failure of the production apparatus or fluctuations in water quality may affect the components of the produced water, and there is a concern that electrolyzed water having normal properties is not produced.

Recently, there has also been a movement to divide and use small containers for a limited purpose, but the greatest disadvantage of electrolyzed water, the low storage stability, has not been fully resolved and has been distributed. The conditions are many and do not satisfy practicality.

Therefore, the present inventor has excellent properties not found in conventional disinfectants, and is a slightly acidic electrolysis that is expected to have a revolutionary effect in infection prevention, food safety, comfortable living, medical care, agriculture and fisheries industry, etc. Providing technology to supply users with disinfectants containing hypochlorous acid as the main disinfecting chemical species, including water, in a general-purpose amount and maintaining normal properties for a practical period. Was an issue.

Hypochlorous acid contained in a bactericide containing hypochlorous acid as a main bactericidal chemical species is an active substance having a strong oxidizing power, and is known to be particularly strongly decomposed by the influence of ultraviolet rays. Furthermore, although the microorganisms are sterilized by their strong oxidizing action, substances that are easily oxidized other than microorganisms are also oxidatively decomposed. That is, hypochlorous acid is unstable mainly because of its high reactivity, decomposition due to light, and consumption due to oxidation of an oxidizable substance. In addition, the disappearance of simple chlorine in equilibrium with hypochlorous acid also promotes decomposition. Therefore, if these causes can be eliminated, a technique for solving this problem can be provided.

Therefore, in order to reduce the ratio of hypochlorous acid lost due to reaction with the container substance in contact with the container, the capacity is increased to the limit that is easy to handle, and the relative amount of hypochlorous acid in contact with the container. Considered to reduce the As a result, by reducing the amount of bactericides containing hypochlorous acid as the main bactericidal chemical species to 2 liters or more, the effective chlorine concentration can be reduced below the practical level for a practical period in distribution. It was found that it can be suppressed to On the other hand, from the convenience of handling, it was found that it is appropriate to use 100 liters or less. Therefore, the capacity of a container filled with a bactericide containing hypochlorous acid as a main bactericidal chemical species is set to 2 liters to 100 liters. In order to be able to confirm that the sealed state of the filled container was maintained, it was sealed with a method capable of proving that it was not opened, and also a single unit in equilibrium with hypochlorous acid In order to minimize chlorine and minimize the influence of rocking stirring during transportation, the container was filled with a bactericide containing hypochlorous acid as the main bactericidal chemical species in a substantially full state. It was set as the 1st aspect for solving.

In addition to the first embodiment, for the convenience of handling manually, the upper limit of the capacity of a container filled with a bactericide containing hypochlorous acid as a main bactericidal chemical species is 50 liters or less, Solve this problem by increasing the stability to 10 liters or more, and eliminating the container price from the disinfectant price and filling the container that can be used repeatedly to increase the economy. It was set as the 2nd aspect for doing. In addition, 3 gallon and 5 gallon containers, which are generally filled with mineral water and distributed, are also optimal for this purpose.

In addition to the first and second embodiments, in order to avoid decomposition of hypochlorous acid by light of a bactericide containing hypochlorous acid as a main sterilizing chemical species, in a metal or light shielding resin container, In order to solve this problem, in the case of metal, in order to avoid consumption of hypochlorous acid due to the reaction of metal and hypochlorous acid and corrosion of the container, the container whose inner surface was coated with resin was filled. It was set as the 3rd aspect.

In addition to the above embodiments, in order to minimize the consumption of hypochlorous acid due to contact between the container and the sterilizing agent, a sterilizing agent containing hypochlorous acid as a main sterilizing chemical species is used, and the inner surface is a fluoropolymer. Filling the container covered with the material was a fourth aspect for solving the problem. The fluoropolymer material in this case refers to all polymer materials of fluorine compounds, and is called a so-called fluororesin or fluororubber.

Further, in addition to the above embodiments, as a light shielding method for avoiding the decomposition of hypochlorous acid by light, a bactericide containing hypochlorous acid as a main sterilizing chemical species, a container having a light shielding coating or a light shielding property Filling a container covered with a film was a fifth aspect for solving this problem. According to this method, an off-the-shelf non-light-shielding container can be used by simple processing, and a material having insufficient light-shielding property despite its high durability against hypochlorous acid can be used, which is economically significant. It should be noted that whether the part to be coated or painted is outside or inside the container can be determined by the material used for painting.

In addition, as described above, it is desirable to make the state of substantially full water in order to minimize the influence of rocking stirring during transportation and to eliminate room for the formation of simple chlorine in equilibrium with hypochlorous acid. Since the effect is maximum when there is no headspace, in addition to each of the above aspects, filling the container with a bactericide containing hypochlorous acid as the main bactericidal chemical species in a state where there is no headspace, The sixth aspect for solving this problem is provided.

Furthermore, among the bactericides having hypochlorous acid as the main bactericidal chemical species, bactericides produced by electrolysis of dilute hydrochloric acid using a diaphragm electrolyzer, so-called slightly acidic electrolyzed water, Since it has a pH of 5 to 6.5, it is highly stable in electrolyzed water. Furthermore, it is different from the fungicides having all other hypochlorous acid as a main fungicide species in that it does not contain salts. . Therefore, since there are no harmful effects caused by salt, such as salt damage and various adverse effects due to crystallization of salt, the usable range is the widest. Therefore, the effect of the present invention can be maximized by providing the container with the slightly acidic electrolyzed water. Therefore, in addition to the above-described embodiments, as a bactericide containing hypochlorous acid as a main bactericidal chemical species, a bactericide produced by electrolysis of dilute hydrochloric acid using a non-diaphragm electrolyzer, that is, a slightly acidic electrolyzed water was filled in a container. This is the seventh aspect for solving this problem.

By the way, the bactericidal agent which uses hypochlorous acid as the main bactericidal chemical species and is filled in a container of the present invention is intended to be used as it is without performing an operation such as dilution. Therefore, it is necessary that what is filled in the container is effective as a disinfectant as it is and not in an excessive concentration. Therefore, the lower limit concentration is 10 ppm, which is the lower limit value of food additive standards for slightly acidic electrolyzed water (slightly acidic hypochlorous acid water), and the upper limit concentration is 600 ppm, which was once notified by the Ministry of Health, Labor and Welfare for infection prevention measures. Therefore, in addition to the above embodiments, the container is filled with a bactericide containing hypochlorous acid as a main bactericidal chemical species having an effective chlorine concentration of 10 ppm or more and 600 ppm or less. It was set as the aspect.

Further, since 10 ppmm or more and 200 ppm or less, which is commonly used for sterilization of food, utensils, and the environment, is appropriate, in addition to the first to seventh aspects, the effective chlorine concentration is 10 ppm or more and 200 ppm or less. Filling the container with a bactericide containing chlorous acid as a main bactericidal chemical species is a ninth aspect for solving this problem.

Furthermore, hypochlorous acid has an equilibrium relationship with elemental chlorine, and if there is a head space in the container, a part of it moves in the form of elemental chlorine. Since simple chlorine is a gas, it has a property of permeating the resin and may be lost to the outside. When elemental chlorine is lost, a portion of hypochlorous acid is lost as elemental chlorine to compensate for it and maintain an equilibrium state. Therefore, in order to prevent hypochlorous acid from being lost as simple chlorine and to keep a bactericide containing hypochlorous acid as the main bactericidal chemical species, it is considered to optimize the inside of the container and optimize it. Checked the condition. And in addition to each said aspect, when filling and sealing the container with the bactericide containing hypochlorous acid as a main sterilization chemical species, the container internal pressure was set to a state of 10 Pa or more and 5 kPa or less. It was set as the 10th aspect for doing.

Furthermore, an article filled with a bactericide containing hypochlorous acid as a main bactericidal chemical species filled by any of the above-described methods was used as an eleventh aspect for solving this problem.

In addition, for convenience in using a bactericidal agent, a method of dispensing an appropriate amount of bactericidal agent filled in a container is also provided. Since the container filled with the bactericide is light-shielding and cannot be visually observed, a means for easily confirming the remaining amount from the outside is provided. That is, it has a mechanism for taking out a necessary amount of a bactericide containing hypochlorous acid as a main bactericidal chemical species from an article filled in the container, and has a function of detecting and displaying the weight of the bactericide remaining in the container. The twelfth aspect for solving this problem is that the server is equipped with an article filled in the container, and the disinfectant is separated and used.

Furthermore, for the convenience of the user, a humidifier, as an instrument suitable for using an article filled in the container or a sterilizing agent having hypochlorous acid as a main sterilizing chemical species in the server, A mode in which at least one of a water sprayer, a gardening sprayer, an indoor spray container, and a portable spray container is attached is defined as a thirteenth mode for solving this problem.

First, an outline of the effects brought about by the present invention will be described. The present invention is a stable and practically stable fungicide containing hypochlorous acid as a main germicidal chemical species, including slightly acidic electrolyzed water, which has been unstable until now and has been difficult to distribute as a fungicide. The container was filled with a sterilizing agent by devising conditions so as to maintain a stable state. As a result, disinfectants with hypochlorous acid as the main disinfectant chemical species, which have superior properties not found in conventional disinfectants, can be distributed, expanding the use and expanding the number of people who can enjoy the benefits. This contributed to the improvement of sanitation level. In addition, since this type of disinfectant has conventionally been generated individually by a user using a generation device, poor adjustment or failure of the generation device or fluctuations in water quality may affect the components of the generated water. It is also possible that normal properties of electrolyzed water were not produced, but such concerns were resolved. Next, the effect of the present invention will be described in more detail.

First, according to the present invention, a bactericide containing hypochlorous acid as a main sterilizing chemical species filled in a container is filled in a container with a capacity of 2 liters or more and 100 liters or less in a substantially full state, and is unopened. Delivering a disinfectant with hypochlorous acid as the main disinfectant chemical species, which has been difficult to transport, to a practical level everywhere Became possible. In addition, since it was possible to check the opening during distribution, it was possible to reliably deliver normal disinfectants to the users.

Furthermore, in the present invention, since the capacity of the container is 10 liters to 50 liters and the container can be used repeatedly, it can be handled by hand and can be distributed more closely, such as over-the-counter sales. became. In addition, the container cost has been reduced and the burden on the user has been reduced.

Furthermore, in the present invention, the container is made of metal or made of metal whose inner surface is coated with resin or light-shielding resin, so that the light-shielding effect is enhanced, and the filled hypochlorous acid is used as the main sterilizing chemical species. The disintegration of the disinfectant by light was completely eliminated, and storage at room temperature for 6 months or more was made possible. This further expanded the distribution range.

Furthermore, in the present invention, the use of a container whose inner surface is coated with a fluoropolymer material eliminates the loss of hypochlorous acid due to the reaction with the substance due to contact with the container, thereby further extending the storage period. Made possible.

Furthermore, in the present invention, by using a container coated with a light-shielding coating or a container coated with a light-shielding film, a ready-made container can be used, and the price of a newly manufactured container can be reduced and used. Contributed to reducing the burden on consumers and promoting distribution.

Furthermore, in the present invention, the bactericide containing hypochlorous acid as the main sterilizing chemical species is filled in a completely full state so that there is no head space in the container, thereby minimizing rocking agitation during distribution. In addition, there is no room for generation of simple chlorine in equilibrium with hypochlorous acid, and it has become possible to more stably distribute bactericides using hypochlorous acid as the main bactericidal chemical species.

Furthermore, the bactericide containing hypochlorous acid as the main bactericidal chemical species, the bactericide produced by electrolyzing dilute hydrochloric acid using a diaphragm electrolyzer, that is, a slightly acidic electrolyzed water, filled the container, Bactericides containing hypochlorous acid as the main sterilizing chemical species are highly stable and can be stored for a longer period of time. Furthermore, they do not contain salts, so that harmful effects caused by salt such as salt damage and salt There is no need to be afraid of various adverse effects due to crystallization, and repeated use on plants and continuous spraying are possible, further expanding the application.

Furthermore, by making the effective chlorine concentration of the bactericide filled with hypochlorous acid the main bactericidal chemical species into 10 ppm or more and 600 ppm or less, the container is taken out from the container and does not require any trouble such as dilution. Now available.

Furthermore, by making the effective chlorine concentration of the sterilizing agent containing hypochlorous acid the main sterilizing chemical species filled in the container to be 10 ppm or more and 200 ppm or less, It can be used immediately under the same conditions without any processing. The risk of mistakes such as incorrect dilution has been eliminated.

Furthermore, when the container is filled with a bactericide containing hypochlorous acid as a main sterilizing chemical and sealed, hypochlorous acid can be absorbed into the container by applying a pressure of 10 Pa to 5 kPa. Suppressing the tendency to be consumed as simple substance chlorine in an equilibrium relationship, the long-term storage of a bactericide filled with hypochlorous acid as the main bactericidal chemical species was made possible.

Furthermore, by providing an article filled with a bactericide containing hypochlorous acid as a main bactericidal chemical species filled by any of the methods of the above embodiments, the unstable hypochlorous acid is mainly contained. The bactericides used as bactericidal chemical species can be stored and distributed stably for a long time in a state where they can be used as they are.

Furthermore, by providing a method for separating and using the disinfectant from an article filled with a disinfectant containing hypochlorous acid as a main disinfectant chemical species, the user can obtain a necessary amount of hypochlorous acid. As a main sterilizing chemical species, it is possible to easily sort and use the sterilizing agent, and it is possible to easily check the remaining amount even when the filled container is opaque. This will be described more specifically with reference to FIGS. 1 and 2 shown as an example. An article 1 in which a container is filled with a bactericide containing hypochlorous acid as a main bactericidal chemical species is mounted on a server 2 having a function of easily separating and using the bactericide. The user can operate the sorting faucet 3 to dispense any necessary amount of bactericide. Further, the weight of the sterilizing agent remaining in the container can be easily detected by the function of sensing it with the weight sensor 6 and displaying it on the display unit 4.

Furthermore, as an instrument using a bactericide containing hypochlorous acid as a main sterilizing chemical species for the server or the article, at least one of a humidifier, a water heater, a garden sprayer, an indoor spray container, and a portable spray container. By supplying any 1 to the user, the disinfectant can be used immediately. In addition, they can be used as a means for teaching an effective method of using a bactericide containing hypochlorous acid as a main bactericidal chemical species, and a suitable effect can be given to the user. .

Next, the present invention will be described in more detail with specific examples. First, as a disinfectant containing hypochlorous acid as a main disinfecting chemical species, slightly acidic electrolyzed water prepared by electrolyzing dilute hydrochloric acid in a non-diaphragm electrolyzer according to a conventional method, and mixing and diluting the electrolyte with water, Electrolyzed dilute saline solution in a diaphragm type electrolytic cell according to the method, strong acid electrolyzed water obtained exclusively from the anode chamber, solution obtained by neutralizing hypochlorite to a weakly acidic or slightly acidic state with acid, etc. Any other sterilizing agent whose main chemical species for sterilization is hypochlorous acid can be used, but it is optimal to use slightly acidic electrolyzed water.

The fungicide at the use concentration means the fungicide at the concentration at which these fungicides are actually used.

The optimum capacity was determined by confirming the preservation of effective chlorine concentration by the following test.

Prepared a slightly acidic electrolyzed water (effective chlorine concentration 32 ppm, pH 5.4) produced by a conventional method in a PET container with each capacity filled and sealed, and the room temperature was completely blocked by assuming complete light shielding Stored in a storage. One sample was opened for each volume every three months, and the effective chlorine concentration (ppm) and pH were measured by the iodometry and glass electrode methods, respectively, and the results are shown in Table 1 of FIG.

At 2 liters, 80% of the original effective chlorine concentration was maintained after 6 months of the target, and it was found that it could withstand circulation sufficiently. In addition, in 20 liters, 90% or more remained in June, and it was shown that the larger the capacity, the better the storage stability.

Accordingly, the filling amount may be any volume from 2 liters to 100 liters depending on the purpose of use. In short, considering the time it takes to consume after opening, it should be considered as short as possible, but not so inconvenient in practice. For example, about 2 liters is sufficient for personal use, and about 100 liters may be required for small business use. In addition, when it is assumed that cargo handling is performed by humans or when the assumed use place is generally limited space, the capacity of the container is desirably 50 liters or less, and the stability of the components For this purpose, the lower limit is more preferably 10 liters. Therefore, it can be said that the amount of 5 gallon or 3 gallon used for supplying water for general purposes is the optimum amount in terms of stability of components, ease of handling, and securing of containers. The expiration date after opening is 1 to 2 weeks as a guide.

Filling in a substantially full state means that the state is full of water that can be controlled by various commonly used manual or automatic filling machines. A method of filling a full water with no head space can be realized by using a container provided with a check valve at the filling port of the container. Examples of such a check valve include a structure in which the valve body floats on water, the valve body is pushed up by the rise of the liquid level accompanying liquid filling, and finally the filling port is closed.

Sealing seal by a method that can prove that it has not been opened is to seal with a lid or stopper made of resin or metal after filling, and when opening it, it must be broken unless part of the lid or stopper is broken. It has a simple structure. Alternatively, it is possible to use a structure that is sealed with a normal lid or stopper, and is provided with a sealing tool such as metal, resin, or paper, and the sealing tool needs to be destroyed when opened.

A container that can be used repeatedly may have a structure that has sufficient strength, can be cleaned both inside and outside after use, and can be sealed again. Note that the lid or plug need not be reusable.

In order to achieve complete light shielding, the container is made of metal or light shielding resin. In the case of a metal, it is necessary to protect the inner surface of the metal other than titanium or non-corrosive alloy with a protective film such as a resin. The light-shielding resin refers to a resin colored with a dark pigment, a resin mixed with carbon or metal powder, and the like.

To prevent consumption of hypochlorous acid by the reaction of the biocidal agent containing hypochlorous acid as the main sterilizing chemical species and the consumption of hypochlorous acid, use a container whose inner surface is coated with a low-reactivity fluoropolymer. It is more desirable to do.

When no metal or light-shielding resin is used as the container material, complete light-shielding ability can be realized by using a container coated with a light-shielding coating or a container coated with a light-shielding film. If it is painted, the outer surface of the container may be painted with a paint containing dark pigment, carbon powder, metal powder, etc. If it is a light-shielding film, dark resin film, metal foil, composite film using metal foil, etc. The outer surface of the container may be covered with

The bactericide produced by electrolyzing dilute hydrochloric acid using a non-diaphragm electrolytic cell is called so-called slightly acidic electrolyzed water or slightly acidic hypochlorous acid water, and can be prepared by a predetermined method. For example, in a generally used generator, 3% by weight hydrochloric acid is used as a raw material, and the electrolytic solution is diluted with water to continuously produce slightly acidic electrolyzed water having an effective chlorine concentration of about 20 ppm and a pH of 5.0 to 6.5. Can be prepared using such an apparatus.

The bactericides containing hypochlorous acid as the main bactericidal chemical species having an effective chlorine concentration of 10 ppm or more and 600 ppm or less can be prepared using the above-mentioned machine, or a commercially available hypochlorite solution can be used. It may be diluted to a concentration and acidified with citric acid, acetic acid, hydrochloric acid or the like, but it is desirable to set the pH around 5. Similarly, those having an effective chlorine concentration of 10 ppm or more and 200 ppm or less can be prepared.

Hypochlorous acid is in equilibrium with elemental chlorine, and part of elemental chlorine may be lost due to the permeability of the container or the like. Therefore, in order to prevent hypochlorous acid from being lost as elemental chlorine and to keep a bactericide containing hypochlorous acid as the main bactericidal chemical species in a stable state, the inside of the container was examined under a pressurized state. A slightly acidic electrolyzed water having an effective chlorine concentration of 35 ppm was prepared by a conventional method, and a 20 liter PET container filled at 5 ° C. and 25 ° C. in a full water state was used as a sample. Samples were stored at room temperature in a completely light-shielded state, opened one by one every three months, and the effective chlorine concentration was measured by iodometry. The results are shown in Table 2 of FIG.

When the container filled at 5 ° C. was returned to room temperature, the internal pressure of the container was 15 Pa. And the pressurization state was always maintained throughout the preservation | save test period. However, in the case of filling at 25 ° C., the inside of the container may be in a reduced pressure state depending on the outside air temperature during the storage period. By this test, when the internal pressure of the container was always 10 Pa or more, it was confirmed that the preservation efficiency of effective chlorine was higher than that filled at room temperature. Presumably, the higher the internal pressure, the better the storage stability. However, considering the pressure resistance of the container and water spillage at the time of opening, the upper limit was set at 5 kPa, which is unlikely to cause such problems.

There are several methods for bringing a pressure of 10 Pa or more and 5 kPa or less into the container when the container is filled and sealed with a bactericide containing hypochlorous acid as a main sterilizing chemical species. For example, as described above, the sterilizing agent is cooled to 5 ° C. or lower at the time of filling, filled with water and sealed, and when the temperature is returned to room temperature, a predetermined internal pressure is obtained by expansion of the liquid. Alternatively, it can be easily realized by using a generally used pressure filling machine.

As a server for easily collecting and using a necessary amount of a bactericide containing hypochlorous acid as a main bactericidal chemical species, a server used for mineral water or the like can be used. However, since the container is opaque, the remaining amount cannot be visually confirmed, but the object can be achieved by sensing the weight. As a method for detecting the weight, for example, when an article filled with a bactericide containing hypochlorous acid as a main sterilizing chemical species is mounted on a server, the weight of the article or a part of the weight is applied as a load. This is possible by installing a weight sensor in the and using its output. Examples of such a weight sensor include an electric detection type using a strain gauge or a piezoelectric element, and a type using a hook or a spring.

There are many ways to use bactericides with hypochlorous acid as the main bactericidal chemical species, but the main usage is the method of pouring the target, the method of spraying, the method of spraying, the method of using as fine mist, etc. It is. Therefore, by attaching the tools to be used in advance to the server, it is possible to promote the effective use of a bactericide containing hypochlorous acid as the main bactericidal chemical species, avoiding the trouble of preparing them. It is. In addition to selling, there are methods of lending.

Next, the present invention will be described in more detail with specific examples. A 5 gallon capacity blow-molded black vinyl chloride container was filled with slightly acidic electrolyzed water having an effective chlorine concentration of 30 ppm and a pH of 5.4 and hermetically sealed. At the time of filling, the disinfectant was cooled to 5 ° C. or lower, filled in a full water state and sealed, and the internal pressure at 20 ° C. was 40 Pa. After being allowed to stand at room temperature for 6 months in this state, the effective chlorine concentration was 26 ppm and the pH was 5.7. In order to remove reactants contained in the resin with the bactericide, the sodium hypochlorite solution with an effective chlorine concentration of 200 ppm was filled in a full state before filling with the bactericide and left for 40 hours. The sodium chlorate solution was discarded and the interior was washed with water.
Next, the same filling material was transferred overseas using sea mail, opened three months after filling, and analyzed the contents. As a result, the effective chlorine concentration was 28 ppm and it was not affected by transportation. confirmed.

Using a container in which a golden paint containing metal powder was baked on the outer surface of a PET 3-gallon container, it was filled with slightly acidic electrolyzed water to produce a product. After filling with water at room temperature and sealing with a plastic stopper, it was squeezed and sealed with an aluminum sealing cap. After 6 months, the room temperature storage sample was opened and inspected, and as a result, both the effective chlorine concentration and pH were within the specified ranges.
