Description

  Embodiments of the present invention relate to a container containing hypochlorous acid water and a method of adding a scent to hypochlorous acid water.

  Examples of electrolyzed water having various functions by electrolyzing water include alkaline ionized water, ozone water, and hypochlorous acid water. Of these, hypochlorous acid water has excellent sterilizing power, is safe for the human body, and is also approved as a food additive.

  As an apparatus for generating such electrolyzed water, for example, there is an apparatus having a one-diaphragm two-chamber electrolytic cell and a two-diaphragm three-chamber electrolytic cell. In the one-membrane two-chamber electrolytic cell, for example, a sodium chloride aqueous solution is allowed to flow as an electrolyte in an electrolytic cell facing the anode chamber containing the anode and the cathode chamber containing the cathode separated by a diaphragm that allows only specific ions to pass therethrough. To produce acidic water and alkaline water in the cathode chamber. Acidic water is a mixture of hypochlorous acid and hydrochloric acid, and alkaline water is sodium hydroxide water or water containing dissolved hydrogen. On the other hand, in the two-membrane three-chamber electrolytic cell, an intermediate chamber filled with an electrolyte solution such as a sodium chloride aqueous solution between the anode chamber and the cathode chamber in order to prevent sodium chloride from being mixed into the generated acidic water and alkaline water. The anion chamber is separated from the intermediate chamber and the anode chamber, the cation exchange membrane is separated from the intermediate chamber and the cathode chamber, and only the anion or cation necessary for electrolysis from the aqueous sodium chloride solution is separated from the anode chamber or The structure is made to pass through the cathode chamber.

  Hypochlorous acid water is generated in the anode chamber, while sodium hydroxide is generated by sodium ions that have permeated through the anion exchange membrane in the cathode chamber and becomes alkaline.

  Hypochlorous acid water is used as sterilizing water. However, hypochlorous acid water generates a small amount of chlorine gas having a characteristic irritating odor due to the nature of hypochlorous acid. In order to mask this irritating odor, it is conceivable to add a fragrance to hypochlorous acid water, but hypochlorous acid tends to be deactivated by reacting with the fragrance, and the effect as sterilizing disinfecting water tends to decrease. Therefore, it is desirable to suppress deactivation as much as possible.

It is the schematic showing an example of the structure of the electrolyzed water generating apparatus which can produce | generate the electrolyzed water used for embodiment. Schematic showing the other structure of the electrolyzed water generating apparatus which can produce | generate the electrolyzed water used for embodiment The partially notched sectional view showing an example of the container containing hypochlorous acid water according to the embodiment is shown.

  A container containing hypochlorous acid water according to an embodiment includes a container, a scent component holding portion provided in the container, a pH value of 3.0 or more and 7.0 or less, and hypochlorous acid of 1 mg / kg or more. Contains hypochlorous acid water having a concentration.

  The scent component holding part includes a base material and a scent component adsorbed on the base material.

  The scent component holding part used in the embodiment can be formed by exposing the base material to an atmosphere containing the scent component and adsorbing the scent component to the base material.

  Moreover, the method of attaching a scent to hypochlorous acid water according to the embodiment includes forming a scent component holding part and transferring the scent component from the scent component holding part to hypochlorous acid water.

  Forming the scent component holding part includes exposing the base material to an atmosphere containing the scent component and adsorbing the scent component to the base material to form the scent component holding part.

  Transferring the scent component from the scent component holding part to the hypochlorous acid water has a pH value of 3.0 to 7.0 and a hypochlorous acid concentration of 1 mg / kg or more. Contacting at least part of the scent component from the scent component holding part by contacting with chlorous acid water.

According to the embodiment, the scent component adsorbed on the substrate can be desorbed by contacting with the hypochlorous acid water, and transferred to the hypochlorous acid water, and the aromatic compound is directly into the hypochlorous acid water. Since it does not contact, hypochlorous acid water can be scented while suppressing deactivation of hypochlorous acid water. This provides hypochlorous acid water that exhibits excellent antibacterial and sterilizing effects in hospitals and daily life cleaning and disinfection work, and has a pleasant scent during and after use. Refers to a state in which the scent component molecules are attracted to the substrate surface by chemical adsorption or physical adsorption, and the concentration of the scent component on the substrate surface is increased. The adsorption of this scent component is reversible.

  Desorption means that the scent component adsorbed on the surface of the base material is released from the surface of the base material by physical action or chemical action such as contact with hypochlorous acid water, and is transferred from the base material surface to hypochlorous acid water. It means a decrease that moves. An atmosphere containing a scent component refers to a solid phase, a liquid phase, a gas phase, or a mixed phase to which an aromatic compound is applied, and the aromatic compound is released into the phase by physical or chemical action. Indicates the state of

  The scent component is a component that is adsorbed to the base material from the atmosphere containing the scent component, and among the compounds such as aromatic compounds, nitrogen compounds, sulfur compounds, low fatty acids, ketones, and esters, The one that does not feel uncomfortable.

  Examples of the base material used in the scent component holding part include a resin or a ceramic.

  As such a base material, a material that does not promote the deactivation of hypochlorous acid water is selected. For example, for resins, PET, polyethylene, polypropylene, polyisobutylene, methacryl, fluorine (Teflon (registered trademark)), vinyl chloride Thermosetting resins such as vinylidene chloride thermoplastic resins and unsaturated polyesters can be used. For ceramics, alumina can be used.

  The scent component holding part can be used as at least a part of members constituting the container.

  A container is formed using at least a part of the scent component holding part, hypochlorous acid water is introduced into the obtained container, and the scent component holding part and the hypochlorous acid water are brought into contact with each other, so that hypochlorous acid water is brought into contact. Scent components can be transferred to chloric acid water.

  When the base material of the scent component holding part is used as a container, it is desirable that the hypochlorous acid water has a light-shielding specification because there is a concern about deactivation due to ultraviolet rays.

  Moreover, as a material used as a container, glass can be used besides the thermoplastic resin, thermosetting resin, and ceramic used as a base material.

  Or a scent component holding | maintenance part can be made independent from the member which comprises a container.

  When the scent component holding part is independent of the container, the material used as the base material can be used in the form of, for example, resin beads, non-woven fabrics, plates or films. Such a base material can be exposed to the atmosphere containing a scent component, and the scent component can be adsorbed to the base material to form the scent component holding part. The obtained scent component holding part can be transferred to hypochlorous acid water by introducing the scent component holding part together with hypochlorous acid water into, for example, a container and bringing the scent component holding part into contact with hypochlorous acid water. .

  As aromatic compounds applicable to the atmosphere containing scent components, for example, lipophilic alcohols including menthol, amines including indole and methoxypyrazine, aldehydes including citral and cinnamaldehyde, methyl acetate and acetic acid Esters including ethyl, isoamyl acetate, ethers including anethole and anisole, eugenol, ketones including dihydrojasmon, lactones including γ-decalactone and wine lactone, terpenes including nerol, and thiols including thioterpineol Uses aromatic compounds having functional groups that are classified, or materials that are composed of two or more different compounds, and that do not change with the oxidizing power of hypochlorous acid and that suppress the deactivation of hypochlorous acid be able to.

The hypochlorous acid water used in the embodiment has a pH value of 3.0 or more and 7.0 or less, and a hypochlorous acid concentration of 1 mg / kg or more, and is contained when the pH is less than 3.0. Hypochlorous acid changes to dissolved chlorine, and undissolved chlorine molecules are scattered in the gas phase. When it exceeds 7.0, the degree of dissociation of hypochlorous acid increases and OCl ⁻ (next The proportion of chlorite ions) increases. The bactericidal effect of OCl ⁻ is as low as about 1/80 compared with hypochlorous acid, and the bactericidal effect cannot be obtained satisfactorily.

  In addition, when the concentration of hypochlorous acid is less than 1 mg / kg, the bactericidal effect cannot be obtained when deactivation of hypochlorous acid occurs.

  As hypochlorous acid water, for example, electrolyzed water can be used.

  As the electrolyzed water, electrolyzed water produced using pure water can be used.

  The anode chamber 154 induces chlorine ions in the intermediate chamber 151 by the anode electrode 156 and generates chlorine gas to generate hypochlorous acid water. The cathode chamber 155 induces sodium ions in the intermediate chamber 151 by the cathode electrode 157. At the same time, hydrogen gas is generated to produce an aqueous sodium hydroxide solution. The former is hypochlorous acid water having an effective chlorine concentration of 20 to 60 ppm and a pH of about 2 to 5, and the latter is an aqueous sodium hydroxide solution having a pH of about 10 to 13. The aqueous sodium hydroxide solution is taken out from the cathode chamber 155 through the discharge line 171 together with the generated hydrogen gas. By providing the gas-liquid separation unit 172 in the discharge line 171, hydrogen gas can be discharged from the discharge line 171 to the outside.

  This hypochlorous acid water is a safe water that has an excellent bactericidal effect and is also approved for food additives.

It is configured. In the present embodiment, the first diaphragm 50a and the second diaphragm 50b are diaphragms having water permeability. For example, each of the first diaphragm 50a and the second diaphragm 50b uses a porous membrane such as a water-permeable microfiltration membrane (MF membrane) or an ultrafiltration membrane (UF membrane). The first diaphragm 50a and the second diaphragm 50b are formed of, for example, an ultrafiltration membrane or a microfiltration membrane having a water permeability of 0.06 to 600 mL / min per 1 cm 2 (square centimeter) when a water pressure of 1 MPa is applied. ing. The first diaphragm 50a and the second diaphragm 50b are each formed of a material containing, for example, titanium oxide and polyvinylidene fluoride (PVDF).

  The cathode 52 and the anode 54 are metal flat plates having a thickness of about 1 mm and are formed in a substantially rectangular shape. A fine through hole (not shown) for allowing liquid to pass through is formed in the central portion (effective reaction region) of the cathode 52 and the anode 54. The cathode 52 is disposed to face the first diaphragm 50a and is in close contact with the first diaphragm 50a. The anode 54 is disposed to face the second diaphragm 50b and is in close contact with the second diaphragm 50b.

  The cathode side housing 30 is bonded to the intermediate housing 20 in substantially parallel to the side surface 21 a on the cathode 52 side of the intermediate housing 20. The cathode side housing 30 has a cathode chamber (second generation chamber) 32 defined by a recess formed in the lower half thereof. The cathode chamber 32 is open at the surface facing the cathode 52 and is in contact with the entire area of the cathode 52. The other surface of the cathode chamber 32 is closed by the wall portion of the cathode side housing 30. Thus, the cathode 52 is provided in the cathode chamber 32. Further, the cathode side housing 30 has an injection port 34 formed at the upper end, and a flow passage 35 communicating the injection port 34 and the cathode chamber 32. The cathode chamber 32 can be filled with water from the inlet 34 through the flow passage 35.

  The stirring case 40 is formed in a rectangular box shape, and is joined to the side surface of the intermediate casing 20 so as to cover the anode 54. The stirring case 40 has a rectangular opposing wall 41a that faces the anode 54 with a gap, a pair of side walls that are erected along both side edges of the opposing wall and are joined to the intermediate housing 20, And an agitating chamber (first generation chamber, anode chamber) 44 defined by the opposing wall 41a and the side wall and in contact with the reaction region of the anode 54.

Further, a central rib (not shown) extending in the vertical direction is provided on the inner surface of the opposing wall 41 a, and the central rib extends across the plurality of partition walls 46. The stirring chamber 44 is partitioned into a plurality of chambers arranged in the longitudinal direction of the stirring case 40 by a plurality of partition walls 46 and a central rib, and each chamber is in contact with the anode 54. The plurality of chambers communicate with or open to the outside through a plurality of communication holes 47 formed in the opposing wall 41a. Furthermore, the lower end and the upper end of the stirring case 40 are opened to form a drain port 48a and a water intake port 48b, respectively. Further, almost the entire side walls 41 a and 41 b are opened, and a water intake port 49 communicating with the stirring chamber 44 is formed. Water is taken into the stirring chamber 44 from the outside (inside the production vessel 12) through these water intakes 48b and 49, and is allowed to come out into the production vessel 12 through the communication hole 47 and the drainage port 48a.

  The intermediate casing 20, the cathode-side casing 30, and the stirring case 40 of the electrode unit 16 described above are each formed of a resin having excellent acid resistance and alkali resistance, such as vinyl chloride, polyprene, and polyethylene.

  As shown in FIG. 2, the electrode unit 16 configured as described above is supported by the lid body 14 and hangs down from the lid body 14 into the production container 12. The upper end portion of the intermediate casing 20 and the upper end portion of the cathode side casing 30 are fitted into the lid body 14 and project outside through the lid body 14. That is, the introduction path 26 and the exhaust path (not shown) of the intermediate casing 20 extend to a position higher than the upper end edge 12a of the generation container 12. Most of the intermediate housing 20, most of the cathode-side housing 30, and the stirring case 40 extend downward from the lid body 14 and are disposed inside the generation container 12. The connection terminal 52 a of the cathode 52 and the connection terminal 54 a of the anode 54 are each connected to the power feeding unit 18 via the wiring 60.

  Unlike the intermediate chamber 22 and the cathode chamber 32, the stirring chamber 44 does not have a sealed structure, that is, has a structure opened in the production container 12, and therefore the stirring chamber 44 of the electrode unit 16 also has a structure. The entire production vessel 12 including the above forms a large anode chamber. Therefore, the electrolyzed water generating apparatus 10 has a two-diaphragm three-chamber structure having the intermediate chamber 22, the cathode chamber 32, and the anode chamber 44 (12) as a whole.

Next, the operation of electrolyzing salt water and generating acidic water (hypochlorous acid water and hydrochloric acid) and alkaline water (sodium hydroxide) by the electrolyzed water generating apparatus 10 configured as described above will be described.
First, as shown in FIG. 2, water is put into the production container 12 through the pouring outlet 15 and the water is accommodated in the production container 12. Part of the injected water enters the stirring chamber 44 through the communication hole 47 and the water intake ports 48a and 49 of the stirring case 40, and the stirring chamber 44 is filled with water. When pouring water, the amount of water injected is adjusted using the scale 12b as a guide so that the height of the water surface WF substantially coincides with the scale 12b. In this embodiment, the water surface WF is formed at a position lower than the upper end edge 12a of the production container 12 in the stirring chamber 44 or more by putting water up to the height of the scale 12b.

  Further, water is injected from the injection port 34 into the cathode chamber 32 to fill the cathode chamber 32 with water. At this time, the water level in the cathode chamber 32 is desirably set higher than the cathode 52 and not more than the water level WF in the production vessel 12. Further, salt water (electrolyte solution) is injected from the inlet 24 to fill most of the intermediate chamber 22 and the introduction path 26 with salt water. At this time, a predetermined amount of the salt water is formed so that the water surface (liquid surface) CF of the salt water is formed in a position higher than the upper end edge 12a of the generation container 12, that is, a position higher than the water surface WF. ,inject. Thereby, a difference (water head difference) D between the water surface WF of the water in the production container 12 and the surface of the salt water, for example, 100 mm is generated. Therefore, the water head pressure corresponding to this water head difference is applied to the salt water in the intermediate chamber 22.

  In the above state, a negative voltage and a positive voltage are respectively supplied from the power supply unit 18 to the cathode 52 and the anode 54, and the salt water in the intermediate chamber 22 is electrolyzed by an electrolytic reaction. Sodium ions ionized in the salt water in the intermediate chamber 22 are attracted to the cathode 52 and flow into the cathode chamber 32 through the first diaphragm 50a. In the cathode chamber 32, water is electrolyzed by the cathode 52 to generate hydrogen gas, and a sodium hydroxide aqueous solution (alkaline water) is generated by the hydrogen gas and sodium ions.

  Chlorine ions ionized in the salt water in the intermediate chamber 22 are attracted to the anode 54, pass through the second diaphragm 50 b, and flow into the stirring chamber (anode chamber, generation chamber) 44. In the stirring chamber 44, chlorine ions give electrons to the anode 54 to generate chlorine gas. The generated chlorine gas is dissolved in water in the stirring chamber 44 to generate acidic water (hypochlorous acid water and hydrochloric acid) from the water stored in the generation container 12. The acidic water generated in this way is supplied from the stirring chamber 44 to the water in the generation container 12 through the communication hole 47. At this time, the plurality of partition walls (fins) 46 provided in the agitation chamber 44 assist the agitation of the anode side electrolytic product to the production vessel 12 and agitation from the intermediate chamber 22 via the second diaphragm 50b. It plays the role of temporarily increasing the concentration of the electrolyte diffusing into the chamber 44 around the electrode. Moreover, the water in the production | generation container 12 is taken in in the stirring chamber 44 at any time, turns into acidic water, and is mixed with the water in the production | generation container 12. Thereby, hypochlorous acid water having a desired pH is generated in the generation container 12.

  The produced hypochlorous acid water can be poured from the pouring outlet 15 of the production container 12 to any container, cup, or other place. The alkaline water generated in the cathode chamber 32 can be discharged from the inlet 34 and used as appropriate.

  Hereinafter, an example is shown and an embodiment is described concretely.

  A commercial odorant-containing home deodorant was placed in a spray container and left for 1 day.

The container body is made of polyethylene terephthalate (PET), and the spray part is made of polypropylene (PP) and polyethylene (PE). In this case, a container main body and a spray part become a base material of a fragrance component holding part.

  Remove the deodorant from the spray container, wash the spray container thoroughly with tap water, and dry for 1 day. After drying, it is confirmed by a sensory test that the fragrance of the home-use deodorant fragrance remains in the container.

  In this spray container, hypochlorous acid water having an effective chlorine concentration of 30 mg / kg and pH 7 was poured into an approximately 400 mL container, sealed with a cap equipped with a spray device, and stored in a cool and dark place.

  FIG. 3 shows a partially cut-away cross-sectional view of a hypochlorous acid-containing spray container.

  As shown in the figure, this hypochlorous acid-containing spray container 1 includes a container body 6 made of PET having an opening at the top of the head, a lid body 7 attached so as to close the opening of the container body 6, and a lid body. The spray head 2 is connected to the spray head 2 via the lid 7, the spray head 2 assembled integrally with the nozzle 7, the nozzle 4 provided at the tip of the spray head 2, the trigger 3 provided below the nozzle 4, and the lid 7. And a flexible suction pipe 5 hanging in the container body 6.

  A hypochlorous acid water 8 is accommodated in the container body 6, and when the trigger 3 is pulled, the hypochlorous acid water 8 is sucked up by the suction pipe 5 and sprayed from the nozzle 4.

  When hypochlorous acid water is sprayed after the passage of one day, it can be seen that the smell of the spray agent felt in the container is felt from the sprayed hypochlorous acid water, and the irritating odor of chlorine is reduced. Moreover, the effective chlorine concentration of hypochlorous acid water in the container maintains 30 mg / kg and pH 7.

  Hypochlorous acid water stored in a container for 2 months has an effective chlorine concentration of 25 mg / kg, pH 7.2, a fragrance of fragrance, and hypochlorite water stored for 3 months has an effective chlorine concentration. It is 22 mg / kg, pH 7.3, and has a fragrance of a fragrance.

  For comparison, when a household deodorant is directly dropped into hypochlorous acid water, both hypochlorous acid and scent components are deactivated.

  This is thought to be due to the deactivation of both hypochlorous acid and scent components when alcohol and aldehyde, which are the main components of essential oils of aromatic compounds, cause a haloform reaction with hypochlorous acid.

  As another comparison, hypochlorous acid water can be stored in a spray container having a container body using a resin in which an fragrance is kneaded on the inner surface. In this case, although the deactivation of hypochlorous acid is unlikely to occur, the hypochlorous acid water does not come into contact with the scent component itself, but comes into contact with the resin surface in which the fragrance is kneaded. The effect of transferring fragrance is reduced. Moreover, although the fragrance | flavor in the part away from the container inner surface among the fragrance | flavor kneaded transfers a fragrance to a spray container, it is hard to contribute to the fragrance of hypochlorous acid water.

These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
