Description

The present invention relates to a chlorine dioxide generator, and more particularly to a chlorine dioxide generator that simultaneously emits an odor that reduces the odor of chlorine dioxide.

One form of chlorine dioxide gas generator used for sterilization of living space is easy to operate because it is used by the user simply opening the package and dissipating chlorine dioxide gas in response to humidity. However, long-term storage is difficult. In addition, the commercial spread is limited because the emission rate of chlorine dioxide varies greatly depending on the atmospheric temperature and especially the atmospheric humidity. The commonly used chlorine dioxide gas generator is a form in which the user starts using the chlorous acid diluent by adding a granular or powder containing a highly water-absorbent resin, an acid, a pH adjuster, etc. be. In this type, liquids, granules, and powders were liable to spill during the operation at the start of use. In addition, the gel tends to soften in the inside of an automobile during the period when the high temperature continues in summer. Therefore, as a form of chlorine dioxide gas generating agent that does not use a liquid, a chlorite diluent is previously hardened into a gel with agar or the like, and the user puts a solid acid component such as citric acid on the gel. There is a format to place it.

In addition, chlorine dioxide gas has a peculiar odor, and alleviation of the unpleasant odor of chlorine dioxide gas generated and diffused by the reaction has been another problem. As a countermeasure to this point, it has been shown that a fragrance is used together in order to alleviate the chlorine dioxide odor of the chlorine dioxide generating agent (see Patent Document 1). Patent Document 1 is a method in which a user adds a solid acid component and a solid fragrance component to an agar-like gel of a chlorite diluted solution at the time of use. At this time, if the acid component and the fragrance component are in the form of granules or powder, they can be handled as one package. However, the method in which the user opens the packaging material and pour it onto the gel has poor operability, and there is a psychological burden due to filling so as not to spill. In addition, spills and clutter still remained.

Furthermore, it has been shown to use tablets in which an acid component and a fragrance component are independently molded (see Patent Document 2). In the case of the chlorine dioxide gas generator of Patent Document 2, since both the acid component and the fragrance component are tablets molded into a size that can be held by hand, they are easy to handle during operation and may be spilled or messed up. The problem that is done has been improved.

However, in the case of the chlorine dioxide gas generating agent of Patent Document 2, each tablet of the acid component and the fragrance component is required, and the manufacturing cost for molding and packing both tablets separately increases. In addition, there are two similar tablets for users without chemical knowledge, which raises the psychological barrier and requires the two tablets to be placed on the gel so that they do not overlap. Therefore, the method of using each tablet of the acid component and the fragrance component is not always a simple method.

As an improvement for this, a method of consolidating two independent types of tablets into one tablet can be considered. However, there is a technical problem of having a role as an acid and a role of releasing a fragrance at the same time, and a problem of manufacturing cost. In addition, calcium silicate is generally used to support the fragrance. Calcium silicate is used as a carrier for fragrances because it absorbs a large amount of oil per weight. However, when calcium silicate, which is poorly soluble in water, is used as a fragrance-supported molded product for the purpose of reducing the unpleasant odor of chlorine dioxide, it swells when it comes into contact with an acid component, and the molded state cannot be maintained. Therefore, the molded product collapses or swells during use, and the aesthetic appearance is impaired.

JP-A-2018-148983 Japanese Unexamined Patent Publication No. 2018-24556

The present invention has been made in view of the above points, and in order to achieve both convenience of handling and reduction of manufacturing cost, the odor of chlorine dioxide generated at the same time as the generation of chlorine dioxide in a single tablet is alleviated. To provide a chlorine dioxide generator to be realized.

That is, the chlorine dioxide generator of the embodiment has a chlorate ion-containing gel body portion in which a gel-like substance containing a chlorate ion is contained in the body portion and the body portion is sealed, and a solid organic substance containing a fragrance. A fragrance-containing organic acid molded product in which the acid molded product is housed and sealed in a coating is provided, and after the container is opened, the fragrance-containing organic acid molded product is unsealed to gel the fragrance-containing organic acid molded product. It is characterized by being placed on an object.

Further, the chlorine dioxide generator is characterized in that the body portion is a resin bag-shaped container or a resin cup-shaped container.

Further, the chlorine dioxide generator is characterized in that the molded product is molded by tableting.

Further, the chlorine dioxide generator is characterized in that a solid organic acid is selected from fumaric acid, phthalic acid and succinic acid.

Further, the chlorine dioxide generator is characterized in that the chlorite ion-containing gel body portion and the fragrance-containing organic acid molded product are housed in an outer container.

Further, the chlorine dioxide generator is characterized in that the outer container is made of earthenware or porcelain.

According to the chlorine dioxide generator of the present invention, a chlorate ion-containing gel body part containing a gel-like substance containing a chlorate ion in the body part and sealing the body part, and a solid organic acid containing a fragrance. The fragrance-containing organic acid molded product is provided by accommodating and sealing the molded product in a coating material, and after opening the body portion, the fragrance-containing organic acid molded product is released from the seal to form a gel-like fragrance-containing organic acid molded product. Since it is placed on an object, it is possible to achieve both convenience of handling and reduction of manufacturing cost, and to alleviate the odor of chlorine dioxide generated at the same time as the generation of chlorine dioxide in a single tablet.

It is an overall schematic diagram of the chlorine dioxide generator of an embodiment. (A) is a perspective view of an example of the body portion, and (b) is a perspective view of another example of the body portion. (A) is a schematic diagram of an organic acid, (b) is a schematic diagram of tablet molding, (c) is a perspective view of a molded product, and (d) is a schematic diagram when a fragrance is sprayed. , (E) are schematic views when the fragrance is impregnated. It is a perspective view which shows the outer container.

The configuration of the chlorine dioxide generator 1 of the embodiment will be described with reference to the overall schematic view of FIG. The chlorine dioxide generator 1 of the illustrated embodiment includes a chlorite ion-containing gel body portion 10 and a fragrance-containing organic acid molded product 20. Further, as shown in FIG. 4 below, the chlorite ion-containing gel body portion 10 and the fragrance-containing organic acid molded product 20 are housed in the outer container 50 and sold.

In the chlorite ion-containing gel body portion 10, the gel-like substance 19 containing chlorite ion is housed inside the body portion 11. The opening 12 of the body portion 11 is sealed. The body portion 11 of the example of FIG. 2A is formed as a resin bag-shaped container 13 in which a resin film is made into a bag. In the figure, it is in the form of a bag, which is generally called a stand pack or the like. The side portions and the openings 12 of the body portion 11 are heat-sealed so that the resin films are fused to each other. After bag making of the resin film, the gel-like substance 19 is filled in the resin bag-shaped container 13 and the opening 12 of the resin bag-shaped container 13 is sealed. A resin material having excellent chemical resistance is selected for the resin film of the body portion 11, and a laminated film is adopted for improving the strength. For example, it is in the form of a laminated film in which 3 to 7 sheets of polypropylene, polyamide resin (nylon resin), polyethylene terephthalate resin (PET resin), etc. are laminated. The capacity of the resin bag-shaped container 13 is appropriately 50 to 200 mL, and the capacity is adjusted according to the period of use. In addition to the shape of the stand pack shown in the figure, a three-way pillow may be used.

FIG. 2B shows a body portion 11 of another example, in which the body portion is composed of a resin cup-shaped container 15. The resin cup-shaped container 15 is formed by injection molding a resin such as polypropylene having excellent chemical resistance. The gel-like substance 19 is filled in the resin cup-shaped container 15, and the sealing film 17 is adhered to the cup opening 16. The sealing film 17 is heat-sealed and fused with the cup opening 16 to seal the cup opening 16. In addition, instead of the sealing film, a packing and a cap may be used for sealing.

As the body portion 11, the resin bag-shaped container 13 or the resin cup-shaped container 15 may be appropriately selected. In the case of the resin bag-shaped container 13, it can be continuously manufactured from the resin film, and the manufacturing is simple. In the case of the resin cup-shaped container 15, since it has a three-dimensional shape, it is stable at the time of installation and easy to handle.

In the gel-like substance 19, a substance (gelling agent) that increases the viscosity by gelation is mixed with water containing chlorite ions. Chlorite ions (ClO ₂ ^-) sources of sodium chlorite (NaClO _2), a chlorite salts typified by potassium chlorite (KClO _{2). Chlorine dioxide (ClO 2} ) is generated upon contact with an organic acid, which will be described later. Chlorine dioxide is a gas (gaseous) at room temperature and diffuses around the body portion 11. As a result, the growth of microorganisms such as bacteria and molds around the chlorine dioxide generator 1 is inhibited.

As the gelling agent, agarose is preferably used. In addition to this, pectin, carrageenan, guar gum, locust bean gum, carboxymethyl cellulose (CMC) are used. Further, polyvinyl alcohol, polyacrylamide and the like are used. The purpose of gelling to increase the viscosity as in the embodiment is to prevent liquid leakage when the chlorine dioxide generator 1 is overturned. In addition, this is to moderate the reaction with the organic acid of the solid described later. In the liquid state, it mixes with organic acids immediately, so it reacts violently and releases chlorine dioxide in a short time.

However, by intentionally forming the gel-like substance 19, the amount of contact with the solid organic acid can be suppressed and the progress of the reaction can be delayed. In particular, since the period of use of the chlorine dioxide generator 1 is assumed to be 1 to 3 months, it is desirable to continue generating chlorine dioxide little by little. The gelling agent added to the gel product 19 is, for example, 0.1 to 1% by weight in the case of agar.

The concentration of chlorite ion in the gel product 19 is approximately 0.1 to 12% by weight in terms of weight of sodium chlorite. The concentration is adjusted according to the concentration of chlorine dioxide generated from the chlorine dioxide generator 1 and the period of use of the chlorine dioxide generator 1. Further, when the amount of chlorite ion increases, the metal ion concentration increases and the effectiveness of the gelling agent decreases. Therefore, the amount of the gelling agent added is also increased according to the concentration.

The fragrance-containing organic acid molded product 20 is an article in which the fragrance-containing solid organic acid molded product 21 is housed in the coating material 22 and sealed. The acid for reacting with the chlorate ion contained in the gel to generate chlorine dioxide must have the ability to gently generate chlorine dioxide for 1 to 3 months and be moldable. Furthermore, the ability to carry a required amount of fragrance component and release it slowly is required. It is preferable that the acid does not attenuate the scent of the fragrance and has a weak odor. In order to moderate the reaction and sustain the reaction for a long period of time, an acidic substance that is sparingly soluble in water and has a strong pH buffering action even if it is highly soluble may be used.

Fumaric acid (HOOC-CH = CH-COOH), phthalic acid (C ₆ H ₄ (COOH) ₂ ), or succinic acid (HOOC- (CH ₂ ) _2- COOH) is selected as the acid component satisfying the above requirements. NS. The organic acid may be a single species or a plurality of species. In addition, other components may be included as long as the above requirements can be satisfied. These organic acids are solid powders at room temperature. In the powder form, as explained in the background technology, it cannot be said that it is easy to handle the chlorine dioxide generator at the start of use. Therefore, the solid organic acid is processed into a molded product having a predetermined shape. Specifically, the solid organic acid is tableted by a tableting machine or the like used for manufacturing pharmaceuticals or the like and formed into a tablet shape such as a disk.

At the time of tableting, the solid organic acid is weighed, and if necessary, excipients and the like are mixed. Then, under the pressure of the locker, the solid organic acid becomes a molded product. Thus, initially, the powdered organic acid becomes a single molded product, which is easier to handle. The size of the organic acid molded product is 10 to 30 mm in diameter and 3 to 10 mm in thickness. The disk shape is preferable from the viewpoint of resistance to cracking during handling. The shape and size of the molded product are designed in consideration of the desired rate of chlorine dioxide generation.

Further, a feature of the organic acid molded product of the embodiment is that the molded product itself contains a fragrance. Since the fragrance and the organic acid are integrated in the molded product, there is no need to add them separately as in the past. Therefore, the psychological barrier after opening is removed. In addition, the organic acid used is a weak acid, and even if it is touched with bare hands, the effect on the human body is extremely small, and the safety is high.

The fragrance is selected from known fragrances, for example, herbs such as lavender, mint (light load), chamomile, flowers such as roses and kinmokusei, and trees (vegetation) such as cypress, citrus and ebony, frankincense and the like. Listed. Any type of component can be used as long as it does not significantly reduce the effect of chlorine dioxide, as long as it is a component that generally makes humans feel aroma. In addition, a plurality of types of fragrances are mixed. The component of the fragrance is usually a liquid (solution) dissolved in water, alcohol, or an organic solvent. The method of incorporating the fragrance into the molded product of the organic acid is appropriate, such as spraying or impregnating the molded product. The fragrance solution may be supported on a powdery or granular organic acid before tableting.

Here, with reference to FIG. 3, a process of forming a molded product from a solid organic acid and a process of containing a fragrance will be described. FIG. 3A is a solid organic acid powder 29. FIG. 3B is an example of tableting, in which the organic acid powder 29 is housed in the mold portions 31 and 32, and the powder 29 is pressurized. FIG. 3C shows the organic acid molded product 21, which is in the stage of being taken out from the mold portions 31 and 32. In FIG. 3D, the fragrance solution 34 is dropped and sprayed on the finished organic acid molded product 21. Alternatively, in FIG. 3E, the finished organic acid molded product 21 is immersed in the fragrance solution 34. Further, as for the tableting method, a wet method may be used in which the perfume liquid is supported on the powdery or granular organic acid and then the tablet is beaten.

The solid organic acid molded product 21 containing the fragrance thus prepared is contained in the coating material 22 and sealed (see FIG. 1). The coating material 22 is made of a resin film bag, and a resin material having excellent chemical resistance and aroma opacity is selected. For example, it is in the form of a laminated film in which 3 to 7 sheets of polyethylene as an adhesive layer are laminated with polypropylene, polyamide resin (nylon resin), polyethylene terephthalate resin (PET resin), or the like. Further, for the purpose of preventing deterioration of the contained fragrance, a laminated film on which aluminum is vapor-deposited to have a light-shielding property, or an aluminum foil for reducing the attenuation of the fragrance is preferably used. In the illustrated example, a mountain-shaped notch is provided for ease of opening. The coating 22 is sealed by heat-sealing fusion, and the fragrance-containing organic acid molded product 20 is completed.

The chlorine dioxide generator 1 is completed by a combination of the chlorite ion-containing gel body portion 10 and the fragrance-containing organic acid molded product 20. However, when it is used to generate chlorine dioxide, it does not look good when the chlorite ion-containing gel body portion 10 and the organic acid molded product 21 are exposed. Therefore, the chlorite ion-containing gel body portion 10 and the organic acid molded product 21 are housed in the outer container 50. The chlorite ion-containing gel body portion 10 and the organic acid molded product 21 are not directly visible from the outside. As an example, the outer container 50 of FIG. 4 is composed of a container main body 51 and a lid 52. The figure shows a state in which the lid portion 52 is separated from the container main body portion 51. Both the container body 51 and the lid 52 of the outer container 50 shown in the figure are earthenware. Alternatively, the outer container 50 may be porcelain.

The main installation location of the chlorine dioxide generator 1 is inside a house such as a dressing room (toilet), a washroom, and a bedroom. Then, chlorine dioxide continues to be generated for 1 to 3 months, and the chlorine dioxide generator 1 is visible to the inhabitants for a long period of time. Then, it is desired that there is no problem in the furnishings of the room and indoors. For this reason, the chlorine dioxide generator 1 is housed inside the outer container 50. Vents 53 are formed in each of the container body 51 and the lid 52 of the outer container 50 of FIG. The generated chlorine dioxide diffuses to the outside from the vent 53. In the figure, the resin bag-shaped container 13 is housed in the tubular container main body 51. Of course, it can be stored instead of the resin cup-shaped container 15.

Here, the usage of the chlorine dioxide generator 1 of the embodiment is generally as follows. First, the opening 12 of the resin bag-shaped container 13 which is the body portion 11 is opened by scissors, a cutter or the like (release of sealing). Alternatively, the sealing film 17 is peeled off from the cup opening 16 of the resin cup-shaped container 15 which is the body portion 11. Next, the organic acid molded product 21 is taken out from the coating material 22. The organic acid used is a weak acid and is highly safe, so you do not need to use gloves. Then, the organic acid molded product 21 is placed on the gel-like product 19 of the resin bag-shaped container 13 or the resin cup-shaped container 15.

The gel-like material 19 has an appropriate viscosity and elasticity, and the organic acid molded product 21 does not settle in the gel-like material 19 after being placed. Therefore, the contact surface between the gel-like substance 19 in which sodium chlorite or the like is dissolved and the organic acid molded product 21 is limited, and since the acid is poorly soluble in water, the organic acid gradually moves toward the gel-like substance 19 side. Dissolve. Therefore, sudden generation of chlorine dioxide is suppressed, and slow and continuous generation of chlorine dioxide is realized. Then, the resin bag-shaped container 13 or the resin cup-shaped container 15 is housed in the container main body 51 of the outer container 50, and the lid 52 is put on the container main body 51. Then, the generated chlorine dioxide diffuses to the outside from the vent 53. Further, the fragrance component contained in the organic acid molded product 21 also diffuses to the outside from the vent 53. Thus, the odor of chlorine dioxide is masked by the fragrance.

As can be understood from this usage, the chlorine dioxide generator is extremely easy to process for generating chlorine dioxide. Moreover, only the organic acid molded product is taken out and placed on the gel-like product after opening, and the treatment is not confused. In addition, since the organic acid molded product that triggers the generation of chlorine dioxide and the fragrance that masks the odor are integrated into the molded product, there is no need to bear the cost of preparing and packaging separate members. Therefore, the low price is added to the simplicity of processing.

[Preparation of gel containing chlorite ion]
Prepare a solution of sodium chlorite crystals (manufactured by Japan Carlit Co., Ltd., Sylbrite 80) in water, mix with an agar solution that is sufficiently dissolved at high temperature, and mix with 5% by weight of sodium chlorite and 1 weight of agar. %. 120 g of the solution was dispensed into a resin bag-shaped container, the opening was sealed by a heat seal, and the agar was cooled to solidify the agar. A plurality of chlorite ion-containing gel bodies were prepared for the experiment.

[Preparation of organic acid molded products containing fragrance]
Fumaric acid was tablet-molded to prepare a disk-shaped molded product having a diameter of 30 mm, a thickness of 8 mm, and a weight of 8 g. The produced molded product was supported with 0.3 g of a floral fragrance of herbal fragrance per molded product. In addition, 0.2 g of a forest-based fragrance of hinoki cypress was supported on the produced molded product. In this way, a plurality of organic acid molded products containing the two types of fragrances were prepared and stored in a sealed container until they were subjected to an experiment.

[Changes in chlorine dioxide concentration]
The above-mentioned chlorite ion-containing gel body was opened, and a fragrance-containing organic acid molded product was placed on the gel-like material. One molded product was placed on one chlorite ion-containing gel body. Then, it was placed indoors, the temperature and humidity were recorded in a data logger, and the cumulative number of days converted to 20 ° C. was calculated. The emission rate of chlorine dioxide was measured at 20 ° C. for 2, 9, 13, 29, and 44 days.

The sample to be measured (the gel body containing chlorite ion / the molded product of the organic acid was placed) was housed in a 4.5 L synthetic resin airtight container and hermetically sealed. It was allowed to stand for about 1 hour without a sudden temperature change in the atmosphere. During this period, the gas inside was sampled from the synthetic resin closed container at least twice, and the concentration of chlorine dioxide gas was measured by a detector tube (manufactured by Gastec Co., Ltd., 23M). When time is plotted on the horizontal axis and chlorine dioxide gas concentration is plotted on the vertical axis, it becomes a straight line rising to the right. Using the slope of a straight line approximated by a linear equation, the number of mg of chlorine dioxide molecules emitted per hour was calculated from the ideal gas law (chlorine dioxide mg / hr). The median temperature of the atmospheric air during the standing time was used as the temperature to be substituted into the ideal gas state equation. Table 1 shows changes in the concentration of chlorine dioxide depending on the cumulative number of days converted to 20 ° C.

From the results in Table 1, it was found that chlorine dioxide continued to be generated even at the cumulative number of days of 44 days. Therefore, it can be said that the combination of the gel-like product containing chlorite ion and the molded product of the organic acid can stably dissipate chlorine dioxide over a relatively long period of time. Throughout the experimental period, no changes such as collapse were observed in the appearance of the organic acid molded product, and the original disk shape was maintained.

After 9 days from the start of the experiment, each sample was further placed in a 4.5 L sealed container made of synthetic resin and sealed for 3 minutes. After sealing for 3 minutes, the gas inside is sampled from a sealed container made of synthetic resin, and the concentration of chlorine dioxide gas is measured with a detector tube (manufactured by Gastec Co., Ltd., 23M). The odor of the fragrance and chlorine dioxide in the container was confirmed.

The chlorine dioxide concentration was 2.4 ppmv in the floral system and 1.3 ppmv in the forest system. The odor intensity according to the six-step odor intensity display method (see Table 2) was 3.0 in the floral system and 3.0 in the forest system. The numerical value of the six-step odor intensity display method is the intensity of the odor that can be easily perceived by humans. The odor of chlorine dioxide was not felt from any of them, and it was confirmed that the unpleasant odor of chlorine dioxide gas was reduced by the masking effect of the fragrance.

[Evaluation of odor]
0.4 g of a forest-based (I) fragrance of hinoki cypress was supported on the above-mentioned molded product. Further, 0.2 g of a floral (II) fragrance of herbs was supported on the molded product per molded product. Further, 0.4 g of a fruit-based (III) flavor having a fruity aroma was supported on the molded product per molded product. In this way, a plurality of organic acid molded products containing three kinds of fragrances were prepared and stored in a sealed container until they were subjected to an experiment. In addition, for comparison, only an organic acid molded product (IV) without carrying a fragrance was also prepared.

The above-mentioned chlorite ion-containing gel body was opened, and a fragrance-containing organic acid molded product was placed on the gel-like material. One molded product was placed on one chlorite ion-containing gel body. Then, it was placed indoors and the odor was measured after 14 days had passed. The results are shown in Table 3.

The odor intensity in the table can be considered as the total value of the fragrance odor and the chlorine dioxide odor. For example, in the case of a forest system (I) sample, the odor intensity is 3.0. If the odor derived from fragrance and the odor derived from chlorine dioxide are separated, the intensity of chlorine dioxide odor is specified as a numerical value indicating how much of the 3.0 is derived from chlorine dioxide by the sense of the experimenter. did. In this case, it means that the odor of chlorine dioxide was felt to be 0.25. Therefore, since the odor intensity of only the molded product (IV) without carrying the fragrance was 2.75, this is all odor derived from chlorine dioxide. The concentration of chlorine dioxide is the concentration detected by the gas detector tube based on the same method as described above.

From the results in Table 3, it was confirmed that the masking effect of the fragrance on the odor of chlorine dioxide was sufficiently exhibited even in the concentration range in which the odor of chlorine dioxide could be reliably detected. On the sample side using the fragrance, the odor of the fragrance is predominant over chlorine dioxide.

[summary]
From a series of verifications, the chlorine dioxide generator can generate chlorine dioxide at a sufficient concentration, while masking the odor peculiar to chlorine dioxide with the odor of the fragrance. Therefore, the user is less likely to feel the unpleasant odor of chlorine dioxide, and since the odor of the fragrance is predominant, it can also function as an air freshener. In particular, since chlorine dioxide, which is effective for sterilization, is continuously diffused for a long period of time, the effects of sterilization and deodorization at the installation site are maintained, and the odor of chlorine dioxide during that period can be eliminated.

The chlorine dioxide generator of the present invention can generate chlorine dioxide for a long period of time by simple handling, and the odor of chlorine dioxide during that period is masked by the fragrance of the fragrance. Highly convenient as.
