[0013] 1, a spray (for example, a can spray) 101 according to an embodiment of the present invention is configured to include a housing (for example, a can) 103 and an actuator 105. A closed space 107 is formed inside the housing 103.
[0014] Water 2 having a specific substance (e.g., chlorine dioxide) dissolved therein and compressed gas (e.g., compressed nitrogen) 109 are contained in closed space 107 inside housing 103. That is, closed space 107 inside housing 103 is filled with aqueous solution 2 of chlorine dioxide and compressed nitrogen 109. Compressed air may be used instead of compressed nitrogen.
[0015] Since the compressed nitrogen 109 is present inside, the chlorine dioxide inside the housing 103 is dissolved and the pressure of the water 2 becomes higher than atmospheric pressure.
[0016] Actuator 105 is provided with fine holes 113. Actuator 105 is provided in housing 103. When actuator 105 is subjected to a predetermined operation such as pressing down, compressed nitrogen 109 pushes water 2 containing dissolved chlorine dioxide inside housing 103, and water 2 passes through fine holes 113 in the form of mist, foam, or gel, and is sprayed outside housing 103.
[0017] A flexible bag 115 is provided inside the housing 103. This bag 115 divides the closed space 107 inside the housing 103 into an intra-bag space 117, which is the space inside the bag 115, and an extra-bag space 119, which is the space outside the bag 115. Water 2 having chlorine dioxide dissolved therein is contained in the intra-bag space 117, and compressed nitrogen 109 is contained in the extra-bag space 119.
[0018] Here, the bag-on-valve will be described. The bag-on-valve is configured with a bag 115 and a valve provided at the opening of the bag 115. The actuator 105 has a valve function and can be considered as a valve. As a result, the sprayer 101 provided with the bag 115 can be called a sprayer with a bag-on-valve. An example of the bag-on-valve is described in JP-T-2009-522173.
[0019] In the bag-on-valve spray, when a specific operation is performed on the actuator 105, the water 2 having chlorine dioxide dissolved therein passes through the fine holes 113 and is sprayed in the form of mist or foam.
[0020] The spray 101 will now be described in more detail.
[0021] Housing 103 is formed, for example, by appropriately processing a thin metal plate, and is configured to include can body 121 and lid 123. Can body 121 is formed in a cylindrical shape with a bottom, and lid 123 closes an opening at the upper end of can body 121. Actuator 105 is provided in lid 123.
[0022] An upper portion of the actuator 105 protrudes from the upper end of the housing 103 , and a lower portion of the actuator 105 recesses into the housing 103 and is located at the upper end portion within the housing 103 .
[0023] A thin and long cylindrical tube 125 extends downward from a lower portion of the actuator 105. The bag 115 is formed in a pouch shape and is provided inside the housing 103.
[0024] The upper end of bag 115 is disposed below actuator 105, so that the lower portion of actuator 105 and bag 115 form intra-bag space 117. Tube 125 extends within intra-bag space 117. The space inside housing 103 and outside bag 115 forms extra-bag space 119.
[0025] Here, the configuration of the bag 115 will be described with reference to Fig. 2(a). The bag 115 is formed by bonding sheet-like materials 115A, 115B, 115C, and 115D together using an overlapping adhesive DL in order to improve the barrier properties.
[0026] Materials 115A to 115D are laminated in this order from the inside to the outside of 115, and a layer of adhesive DL is provided between each of the materials 115A to 115D.
[0027] The material 115A may be, for example, L-LDPE80 (thermoplastic linear polyethylene), and the materials 115B and 115D may be, for example, PET12 (polyethylene terephthalate).
[0028] The material 115C may be, for example, EVOH12 (ethylene vinyl alcohol copolymer), and the adhesive DL may be, for example, a dry lamination adhesive.
[0029] The configuration of the bag 115 may be modified as shown in FIG. 2(b).
[0030] 2(b), for example, L-LDPE80 (thermoplastic linear polyethylene) is used as the material 115E, and for example, PET12 (polyethylene terephthalate) is used as the materials 115F and 115G. Note that for example, a dry lamination adhesive is used as the adhesive DL.
[0031] 2(b), a transparent deposition is performed on the surface of material 115G on the adhesive DL side (the surface in contact with adhesive DL). Transparent deposition is a process in which an inorganic material is evaporated in the air to form a coating of the inorganic material on the base film (material 115G) for the purpose of improving the barrier property.
[0032] In the embodiment shown in FIG. 2(b), in addition to the surface of material 115G facing the adhesive DL (the surface in contact with the adhesive DL), a transparent vapor deposition may be applied to the surface of material 115F facing the adhesive DL on the material 115G side (the surface in contact with the adhesive DL on the material 115G side).
[0033] 2(b), PE60 (polyethylene) may be used as material 115E, and PET12 (polyethylene terephthalate) may be used as materials 115F and 115G. In this case, a transparent deposition is performed on the surface of material 115G on the adhesive DL side (the surface in contact with adhesive DL).
[0034] Here, the operation of the spray 101 will be described.
[0035] In the initial state, the space inside the bag 117 contains water 2 with chlorine dioxide dissolved therein, the space outside the bag 119 contains compressed nitrogen 109, and the actuator 105 is not being pressed down.
[0036] In the above initial state, the actuator 105 is pressed down. Then, the water 2 with chlorine dioxide dissolved therein in the space inside the bag 117 is pushed by the compressed nitrogen 109 in the space outside the bag 119, and passes through the tube 125 and the pores 113 of the actuator 105 and is sprayed outside the spray 101.
[0037] Next, a method for manufacturing the spray 101 will be described.
[0038] First, water (aqueous solution of chlorine dioxide) 2 in which a specific substance (for example, chlorine dioxide) is dissolved is produced by a substance dissolving process. In the substance dissolving process, chlorine dioxide and substances other than chlorine dioxide, which are made of a material through which chlorine dioxide permeates, are placed inside a first vessel. After this, the water and the first vessel are placed inside a second vessel. In this state, the chlorine dioxide that has permeated the first vessel and come out of the first vessel is dissolved in the water containing the second vessel.
[0039] Next, in the injection process (filling process), compressed nitrogen 109 and water 2 having dissolved therein the chlorine dioxide produced in the substance dissolving process are poured into a spray housing having a housing 103 with a closed space 107 formed therein and an actuator 105 provided in the housing 103.
[0040] In a configuration in which the bag 115 is provided inside the housing 103, the water 2 having chlorine dioxide dissolved therein is placed in the space 117 inside the bag, and the compressed nitrogen 109 is placed in the space 119 outside the bag.
[0041] The manufacturing method of the spray 101 will now be described in more detail with reference to FIG.
[0042] A bag-on-valve (BOV) installed in the lid 123 is inserted into the canister body 121 (S1). In this state, the upper part of the actuator 105 protrudes outside the canister body 121.
[0043] Next, the lid portion 123 is crimped and attached to the can body portion 121, and compressed nitrogen 109 is poured into the space outside the bag 119 (S3).
[0044] Next, the pressure of the compressed nitrogen 109 in the bag exterior space 119 is checked as necessary (S5), and the water 2 with chlorine dioxide dissolved therein is poured into the bag interior space 117 from the actuator 105 (S7). After this, the mouth of the valve (the actuator 105 and its vicinity) is cleaned (S9).
[0045] In the sprayer 101, water 2 having chlorine dioxide dissolved therein and compressed nitrogen 109 are contained in a can 103, and when an actuator 105 is pressed down, the water 2 having chlorine dioxide dissolved therein is sprayed to the outside of the can 103. This makes it possible to obtain the required chlorine dioxide in the form of a spray, and also makes it easier to use the obtained chlorine dioxide.
[0046] For example, the dissolution of chlorine dioxide in water slows down the dispersion speed of chlorine dioxide, making it easier to use. Also, water 2 in which only chlorine dioxide is dissolved can be easily sprayed in a uniform mist onto a table to be sterilized, and chlorine dioxide is gradually released from the water, allowing the sterilizing effect to be sustained.
[0047] In the sprayer 101, the closed space inside the housing 103 is divided by the bag 115 into an inner-bag space 117 and an outer-bag space 119. The water 2 having chlorine dioxide dissolved therein is contained in the inner-bag space 117, and the compressed nitrogen 109 is contained in the outer-bag space 119.
[0048] As a result, water 2 containing chlorine dioxide can be sprayed from actuator 105 regardless of the attitude of spray 101. In contrast, in an embodiment in which a bag is not provided as shown in Fig. 7, the following occurs. Even if actuator 105 is pressed with actuator 105 positioned downward, water 2 containing chlorine dioxide is not sprayed from actuator 105, and nitrogen in can 103 may come out. In addition, since bag 115 is provided, compressed nitrogen 109 and water 2 containing chlorine dioxide are not in contact with each other, so that chlorine dioxide, etc. are prevented from deteriorating even if stored for a long period of time.
[0049] As shown in FIG. 7, the bag 115 may be omitted from the sprayer 101 shown in FIG.
[0050] 7, since no bag is provided in the housing 103, only one closed space 107 exists, and the water 2 having chlorine dioxide dissolved therein and the compressed nitrogen 109 are in direct contact with each other inside the housing 103. This allows the capacity of the water 2 having chlorine dioxide dissolved therein and the compressed nitrogen 109 to be increased.
[0051] In the sprayer 101 shown in FIG. 7, when the actuator 105 is placed on top and the housing 103 is placed on the bottom, the water 2 having chlorine dioxide dissolved therein is present on the bottom, and the compressed nitrogen 109 is present on the top.
[0052] With actuator 105 facing up and housing 103 facing down, actuator 105 is pushed down so that the pressure of compressed nitrogen 109 causes water 2 containing dissolved chlorine dioxide inside housing 103 to be sprayed to the outside of housing 103.
[0053] Here, an example of an aqueous solution producing apparatus (an aqueous chlorine dioxide producing apparatus) 1, which is an apparatus for carrying out the above-mentioned substance dissolving step (chlorine dioxide dissolving step), will be described with reference to Figs. 3 to 5.
[0054] The aqueous solution producing apparatus (eg, an apparatus for producing an aqueous chlorine dioxide solution 2) 1 is configured to include a first vessel 3 and a second vessel 5.
[0055] The first vessel 3 is made of a material that allows a predetermined substance (for example, chlorine dioxide 15) to permeate, and contains chlorine dioxide 15 and a substance other than chlorine dioxide 17 inside. The second vessel 5 contains water 7 and the first vessel 3 inside. The chlorine dioxide 15 that permeates the first vessel 3 and comes out of the first vessel 3 is dissolved in the water 7 in the second vessel 5. The water 7 can be, for example, pure water such as "purified water" as specified in the Japanese Pharmacopoeia.
[0056] The aqueous solution manufacturing apparatus 1 is also provided with a substance combining section 9. In the substance combining section 9, a first pre-reactant substance (e.g., chlorous acid) 11 and a second pre-reactant substance (e.g., citric acid) 13 are combined.
[0057] The chlorous acid 11 and citric acid 13 combined by the substance combining unit 9 undergo a chemical reaction to generate chlorine dioxide 15. The chlorous acid 11 and citric acid 13 exist in the form of an aqueous solution, for example.
[0058] The chemical reaction between chlorous acid 11 and citric acid 13 can be expressed as a reaction formula: 15NaClO2 + 4C(OH)(CH2COOH)2COOH → 12ClO2 + 4C6H5Na3O7 + 3NaCl + 2H2O. Here, the "C6H5Na3O7", "NaCl", and "H2O" produced in the above reaction formula are by-products (unnecessary substances) that make up the substance 17 other than chlorine dioxide.
[0059] The first container 3 is made of polypropylene, polyethylene, or silicone This allows only the chlorine dioxide 15 generated by the above chemical reaction to pass through the first vessel 3 and dissolve in the water in the second vessel 5. On the other hand, the second vessel 5 is made of a material that is impermeable to the water 7, chlorine dioxide 15, and by-products 17, such as glass or a synthetic resin with a prescribed coating.
[0060] The first vessel 3 is composed of a first tube. The second vessel 5 is composed of a second tube. Moreover, the second tube 5 is composed of a synthetic resin or the like that is appropriately coated as described above. This prevents the substances described in the above reaction formula from passing through the second tube 5. The first vessel 3 and the second tube 5 are, for example, flexible.
[0061] The first tube 3 is inserted in the second tube 5. The first tube 3 is configured so that chlorine dioxide 15 and a substance other than chlorine dioxide 17 flow through it. The second tube 5 is configured so that water flows through a space 19 outside the first tube 3.
[0062] The first tube 3 is formed in an elongated tubular shape such as a cylindrical shape, and the second tube 5 is also formed in an elongated tubular shape such as a cylindrical shape. The outer diameter of the first tube 3 is smaller than the inner diameter of the second tube 5.
[0063] The longitudinal direction of the first tube 3 and the longitudinal direction of the second tube 5 coincide with each other, and the first tube 3 extends within the second tube 5. A cylindrical space 19 is formed in the portion of the second tube 5 excluding the first tube 3, and water 7 flows through this cylindrical space 19.
[0064] The direction in which the chlorine dioxide 15 and the substance other than chlorine dioxide 17 flow coincides with the longitudinal direction of the first tube 3 , and the direction in which the water 7 flows coincides with the longitudinal direction of the second tube 5 .
[0065] The direction in which chlorine dioxide 15 and substances other than chlorine dioxide 17 flow in the first tube 3 is opposite to the direction in which water 7 flows in the second tube 5 but outside the first tube (see the arrow in Figure 4).
[0066] The apparatus 1 for producing an aqueous chlorine dioxide solution will now be described in more detail.
[0067] As shown in Fig. 3, the chlorine dioxide aqueous solution producing apparatus 1 is configured to include a stand 21, a first pre-reaction substance tank (e.g., a tank for chlorous acid) 23, and a second pre-reaction substance tank (e.g., a tank for citric acid) 25. Also, as shown in Fig. 3, the chlorine dioxide aqueous solution producing apparatus 1 is configured to include a water tank 27, a tank 29 for an aqueous solution of chlorine dioxide 15, and a by-product tank 31.
[0068] In addition, as shown in FIG. 3, the chlorine dioxide aqueous solution manufacturing apparatus 1 is provided with a first pre-reaction substance pump (e.g., a tube pump for chlorous acid) 33, a second pre-reaction substance pump (e.g., a tube pump for citric acid) 35, and a water pump 37.
[0069] Furthermore, the production apparatus 1 for the aqueous chlorine dioxide solution is provided with a predetermined substance permeation section (for example, a chlorine dioxide permeation section) 39, a temperature adjustment section 41, and a control section 43 (a control section including a CPU and a memory, not shown).
[0070] The tanks 23, 25, 27, 29, 31 and the pumps 33, 35, 37, etc. are mounted on a stand 21. Each of the pumps 33, 35, 37 is, for example, a variable discharge tube pump.
[0071] The chlorous acid tank 23 stores an aqueous solution of chlorous acid 11, the citric acid tank 25 stores an aqueous solution of citric acid 13, and the water tank 27 stores water 7. The chlorine dioxide 15 aqueous solution tank 29 stores an aqueous solution 2 of chlorine dioxide 15, and the by-product tank 31 stores by-product 17.
[0072] An intake tube 45 extends from the intake port of the chlorous acid tube pump 33. The tip of the intake tube 45 is inserted into the chlorous acid tank 23. A discharge tube 47 extends from the discharge port of the chlorous acid tube pump 33.
[0073] An intake tube 49 extends from the intake port of the citric acid tube pump 35. The tip of the intake tube 49 is inserted into the citric acid tank 25. A discharge tube 51 extends from the discharge port of the citric acid tube pump 35.
[0074] The tip of the discharge tube 47 and the tip of the discharge tube 51 are connected to each other, and this connection portion forms a material combining section 9. The first tube 3 extends from the material combining section 9 toward the by-product tank 31.
[0075] The substance combining section 9 allows the aqueous solution of chlorous acid 11 and the aqueous solution of citric acid 13 to mix together and undergo a chemical reaction, producing chlorine dioxide 15 and by-product 17. The chlorine dioxide 15 and by-product 17 flow through the first tube 3 toward the by-product tank 31.
[0076] An intake tube 53 extends from the intake port of the water pump 37. The tip of the intake tube 53 is inserted inside the water tank 27. A discharge tube 55 extends from the discharge port of the water pump 37.
[0077] The tip of the discharge tube 55 is connected to the second tube 5, and the second tube 5 extends from this connection point toward the tank 29 for the aqueous solution of chlorine dioxide 15. In addition, a discharge tube 30 extends from the tip of the second tube 5.
[0078] The tip of the discharge tube 30 is inserted into the tank 29 for the aqueous solution of chlorine dioxide 15. This allows the water 7 and the aqueous solution 2 of chlorine dioxide 15 to flow from the water tank 27 toward the tank 29 for the aqueous solution of chlorine dioxide 15.
[0079] A part of the first tube 3 in the longitudinal direction (for example, most of the middle part) extends long inside the second tube 5 as shown in Fig. 4 and Fig. 5. The part of the first tube 3 that extends long inside the second tube 5 serves as a chlorine dioxide permeable section 39. In the chlorine dioxide permeable section 39, the chlorine dioxide 15 comes out of the first tube 3 and dissolves in the water 7 in the second tube 5.
[0080] The temperature adjusting section 41 shown in FIG. 3 adjusts the temperature of the first tube 3 and the second tube 5 in a part of the longitudinal direction of the chlorine dioxide permeation section 39 (for example, most of the middle part). That is, the temperature adjusting section 41 adjusts the temperature of the aqueous solution of chlorous acid 11, the aqueous solution of citric acid 13, the chlorine dioxide 15, the by-product 17, and the water 7. The temperature of the first tube 3 and the second tube 5 is appropriately adjusted, for example, in the range of −9° C. to 60° C. At the temperature adjusting section 41, the first tube 3 and the second tube 5 forming the chlorine dioxide permeation section 39 extend in a coil shape (spiral shape) as shown in FIG. 3. Note that, in the temperature adjusting section 41, the chlorine dioxide permeation section 39 may extend in a bent shape such as a meandering shape.
[0081] Temperature adjustment section 41 will be further described with reference to Fig. 3. Temperature adjustment section 41 is configured to include a container 42, a predetermined liquid 44 such as antifreeze liquid contained in container 42, and a temperature regulator 46 that adjusts the temperature of the predetermined liquid. A coil-shaped chlorine dioxide permeation section 39 is contained in the predetermined liquid 44.
[0082] One longitudinal end of the second tube 5 (the end on the water pump 37 side) is connected to a first connection part 59 of the Tee 57 as shown in Fig. 5(b). A second connection part 61 of the Tee 57 is connected to the discharge tube 55.
[0083] The other longitudinal end of the second tube 5 (the end on the side of the tank 29 for the aqueous solution of chlorine dioxide 15) is connected to a first connection part 65 of a Tee 63 as shown in FIG. 5(c). A second connection part 67 of the Tee 63 is connected to the discharge tube 30.
[0084] As shown in Fig. 5(b), a bushing 71 is installed at the third connection portion 69 of the tee 57. As shown in Fig. 5(c), a bushing 75 is installed at the third connection portion 73 of the tee 63.
[0085] The first tube 3 passes through each of the bushes 71, 75 and into the second tube 5. Note that what is indicated by reference numeral 77 in Figures 5(b) and (c) is a deformation prevention member for preventing deformation of the first tube 3. The deformation prevention member 77 is formed in a cylindrical shape and has high rigidity.
[0086] In the state shown in Fig. 5(b), the bushing 71 and the first tube 3 are sandwiched with a predetermined pressure by the third connection part 69 of the Tee 57 and the deformation prevention member 77. Even in the state shown in Fig. 5(c), the bushing 75 and the first tube 3 are sandwiched with a predetermined pressure by the third connection part 73 of the Tee 63 and the deformation prevention member 77.
[0087] 3 to 5, when the pumps 33, 35, and 37 are driven, the chlorine dioxide 15, by-products 17, water 7, and the like flow without leaking out of the first tube 3 and the second tube 5. It is preferable that the portion of the first tube 3 that protrudes outside the second tube 5 is coated, like the second tube 5, to prevent the water 7, chlorine dioxide 15, and by-products 17 from passing through.
[0088] Next, the operation of the apparatus 1 for producing an aqueous chlorine dioxide solution will be described.
[0089] In the initial state, the chlorous acid tank 23 contains an aqueous solution of chlorous acid 11, the citric acid tank 25 contains an aqueous solution of citric acid 13, the water tank 27 contains water 7, and the aqueous solution tank 29 and the by-product tank 31 are empty. Also, the pumps 33, 35, and 37 are stopped.
[0090] In the above initial state, first, the temperature is adjusted by the temperature adjustment unit 41 under the control of the control unit 43. Then, the pumps 33, 35, and 37 are operated. The pumps 33 and 35 are operated, for example, intermittently. This is because only a small amount of chlorine dioxide 15 is required to be generated per given time. In contrast, the water pump 37 is operated, for example, continuously.
[0091] As a result, the aqueous solution 2 of chlorine dioxide 15 is stored in the tank 29 for the aqueous solution of chlorine dioxide 15, and the by-products 17 are stored in the tank 31 for the by-products.
[0092] In the above description, the water 2 in which chlorine dioxide is dissolved is exemplified as the aqueous solution, but water in which another substance (for example, a fragrance) is dissolved instead of chlorine dioxide may be used. [Explanation of symbols]
