本発明によれば、保存期間中の次亜塩素酸水における次亜塩素酸濃度が低減しにくい。
According to the present invention, it is difficult to reduce the hypochlorous acid concentration in the hypochlorous acid water during the storage period.
以下、本発明の好ましい実施形態を説明する。なお、本実施形態は本発明の一実施態様にすぎず、本発明の要旨を変更しない範囲で実施態様を変更できることは言うまでもない。
Hereinafter, preferred embodiments of the present invention will be described. Needless to say, the present embodiment is only one embodiment of the present invention, and the embodiments can be changed without changing the gist of the present invention.
図１に示されるように、除菌装置１０は、次亜塩素酸水と、次亜塩素酸水を貯留する容器１１と、を具備する。
As shown in FIG. 1, the sterilizing device 10 includes a hypochlorite water and a container 11 for storing the hypochlorite water.
次亜塩素酸水は、例えば、塩化カリウム水溶液又は塩化ナトリウム水溶液を有隔膜電解槽内で電気分解して、陽極側から得られる水溶液又は塩酸を無隔膜電解槽内で電気分解して、水で希釈して得られる液体である。容器１１に貯留される次亜塩素酸水に含まれる次亜塩素酸の初期濃度は、例えば、次亜塩素酸水の全質量に対して５ｐｐｍ以上であることが好ましく、更に好ましくは１０ｐｐｍ以上であり、特に好ましくは、３０ｐｐｍ以上である。また、次亜塩素酸水に含まれる塩酸の初期濃度は、例えば、次亜塩素酸水の全質量に対して１０ｐｐｍ未満であることが好ましく、更に好ましくは５ｐｐｍ未満であり、特に好ましくは、１ｐｐｍ未満である。塩酸濃度が高いほど液中の塩化水素の割合が増加するため、塩化水素による容器の劣化が促進される。また、揮発した塩化水素ガスは樹脂容器の層間剥離を生じさせ、脆弱化を起こす可能性がある。加えて、溶液のｐＨが低下することにより塩化物イオン量が増加し、塩素ガスや塩化水素ガスが発生しやすく、次亜塩素酸分子の分解が進行する。
For hypochlorite water, for example, an aqueous solution of potassium chloride or an aqueous solution of sodium chloride is electrolyzed in a diaphragmatic electrolytic cell, and an aqueous solution or hydrochloric acid obtained from the anode side is electrolyzed in a diaphragmatic electrolytic cell, and the solution is made of water. It is a liquid obtained by diluting. The initial concentration of hypochlorous acid contained in the hypochlorous acid water stored in the container 11 is preferably, for example, 5 ppm or more, more preferably 10 ppm or more, based on the total mass of the hypochlorous acid water. Yes, and particularly preferably 30 ppm or more. The initial concentration of hydrochloric acid contained in the hypochlorous acid water is, for example, preferably less than 10 ppm, more preferably less than 5 ppm, and particularly preferably 1 ppm with respect to the total mass of the hypochlorite water. Is less than. The higher the hydrochloric acid concentration, the higher the proportion of hydrogen chloride in the liquid, which accelerates the deterioration of the container due to hydrogen chloride. In addition, the volatilized hydrogen chloride gas may cause delamination of the resin container and cause fragility. In addition, as the pH of the solution decreases, the amount of chloride ions increases, chlorine gas and hydrogen chloride gas are likely to be generated, and the decomposition of hypochlorite molecules proceeds.
容器１１は、内部空間に液体を貯留可能なボトル形状である。容器１１は、上方に口部１２を有する。口部１２を通じて、容器１１の内部区間と外部とが連通されている。口部１２には、スプレーノズル１３（噴霧機構）が取り付けられている。スプレーノズル１３は、ユーザがレバー１４を引くことによって、容器１１の内部空間に貯留されている次亜塩素酸水を、ノズル部１５からミストとして噴霧するものである。

The inner section of the container 11 and the outside are communicated with each other through the mouth portion 12. A spray nozzle 13 (spray mechanism) is attached to the mouth portion 12. The spray nozzle 13 sprays the hypochlorite water stored in the internal space of the container 11 as a mist from the nozzle portion 15 by the user pulling the lever 14.
容器１１は、次亜塩素酸水の失活を抑制する材質からなる。例えば、容器１１は、高密度ポリエチレンの成型品である。高密度ポリエチレンとは、繰り返し単位であるエチレンが殆ど直鎖状に結合したものであり、密度が０．９４２以上のポリエチレンをいう。容器１１は、ボトル形状に限定されず、例えばバッグ形状であってもよいが、複数の層が積層された構造でないこと、例えば、ポリエチレンとアルミニウムとのラミネートフィルムからなるものでないことが好ましい。また、容器１１は、次亜塩素酸水が失活しないような、ガス透過性が低いものが好ましく、好ましくは、高密度ポリエチレン製のボトル形状の容器１１の肉厚は、０．１ｍｍ以上である。より好ましくは、０．５ｍｍ以上である。また、容器１１は、遮光性を有するものが好ましい。
The container 11 is made of a material that suppresses the deactivation of hypochlorite water. For example, the container 11 is a molded product of high-density polyethylene. High-density polyethylene is polyethylene in which ethylene, which is a repeating unit, is bonded almost linearly, and has a density of 0.942 or more. The container 11 is not limited to the shape of a bottle and may be in the shape of a bag, for example, but it is preferable that the container 11 does not have a structure in which a plurality of layers are laminated, for example, it is not made of a laminated film of polyethylene and aluminum. Further, the container 11 preferably has a low gas permeability so that the hypochlorite water does not deactivate, and preferably, the wall thickness of the bottle-shaped container 11 made of high-density polyethylene is 0.1 mm or more. be. More preferably, it is 0.5 mm or more. Further, the container 11 preferably has a light-shielding property.
容器１１は、高密度ポリエチレンの２層（内層、外層）、またはそれ以上の多層からなるものであってもよい。内層は、顔料を含有しないことが好ましい。外層は、遮光性を向上させることを目的として顔料を含有してもよい。含有させる顔料としては、例えば、酸化チタン、酸化鉄、カーボンブラックなどの無機系顔料や、アゾ系、フタロシアニン系、スレン系などの有機顔料が挙げられる。
The container 11 may be composed of two layers (inner layer and outer layer) of high-density polyethylene or more layers. The inner layer preferably does not contain a pigment. The outer layer may contain a pigment for the purpose of improving the light-shielding property. Examples of the pigment to be contained include inorganic pigments such as titanium oxide, iron oxide and carbon black, and organic pigments such as azo-based, phthalocyanine-based and slene-based pigments.
容器１１は、口部１２が密封された状態において、除菌装置が２５℃の環境温度において１ヶ月間放置されたときに、次亜塩素酸水が含有する次亜塩素酸濃度が、初期濃度の９０％以上を保持する。また、容器１１は、口部１２が密封された状態において、除菌装置が４０℃の環境温度において１ヶ月間放置されたときに、次亜塩素酸水が含有する次亜塩素酸濃度が、初期濃度の８０％以上を保持する。

容器Ａ，Ｂに、試験液Ａ，Ｂ，Cを各容器の容量だけそれぞれ貯留させて、保存温度２５℃、４０℃で、３０日間保管した。０～３０日目の間の所定の各日において容器Ａ，Ｂ，Ｃにそれぞれ貯留されている試験液Ａ，Ｂの有効塩素濃度を測定し、０日目に対する百分率を算出した。その結果を、表１に示す。なお、試験液Ｃについては１４日目までの試験結果である。 [Preservation test 1]
Test solutions A, B, and C were stored in containers A and B by the volume of each container, and stored at storage temperatures of 25 ° C. and 40 ° C. for 30 days. The effective chlorine concentrations of the test solutions A and B stored in the containers A, B and C respectively were measured on each predetermined day between the 0th and 30th days, and the percentage with respect to the 0th day was calculated. The results are shown in Table 1. The test solution C is the test result up to the 14th day.
［保存試験２］
容器Ｃ，Ｄ，Ｅ，Ｆ，Ｇに、試験液Ｄを各容器の容量だけそれぞれ貯留させて、保存温度４０℃で、３ヶ月間保管した。０日目から４ヶ月後までの間の所定の日において容器Ｃ，Ｄ，Ｅ，Ｆ，Ｇにそれぞれ貯留されている試験液Ｃの有効塩素濃度を測定し、０日目に対する百分率を算出した。その結果を、表２に示す。なお、実施例２については２５℃保存を行なっておらず、実施例３及び比較例２～４の２５℃保存については３ヶ月目までの試験結果である。 [Preservation test 2]
The test solution D was stored in the containers C, D, E, F, and G by the volume of each container, and stored at a storage temperature of 40 ° C. for 3 months. The effective chlorine concentration of the test solution C stored in each of the containers C, D, E, F, and G was measured on a predetermined day from the 0th day to 4 months later, and the percentage with respect to the 0th day was calculated. .. The results are shown in Table 2. Note that Example 2 was not stored at 25 ° C., and Examples 3 and Comparative Examples 2 to 4 were stored at 25 ° C. as test results up to the third month.
容器Ｃ，Ｄ，Ｅ，Ｆ，Ｇに、試験液Ｄを各容器の容量だけそれぞれ貯留させて、保存温度４０℃で、３ヶ月間保管した。０日目から４ヶ月後までの間の所定の日において容器Ｃ，Ｄ，Ｅ，Ｆ，Ｇにそれぞれ貯留されている試験液Ｃの有効塩素濃度を測定し、０日目に対する百分率を算出した。その結果を、表２に示す。なお、実施例２については２５℃保存を行なっておらず、実施例３及び比較例２～４の２５℃保存については３ヶ月目までの試験結果である。 [Preservation test 2]
The test solution D was stored in the containers C, D, E, F, and G by the volume of each container, and stored at a storage temperature of 40 ° C. for 3 months. The effective chlorine concentration of the test solution C stored in each of the containers C, D, E, F, and G was measured on a predetermined day from the 0th day to 4 months later, and the percentage with respect to the 0th day was calculated. .. The results are shown in Table 2. Note that Example 2 was not stored at 25 ° C., and Examples 3 and Comparative Examples 2 to 4 were stored at 25 ° C. as test results up to the third month.
表１から明らかなように、同じ保存条件で比較すると、容器Ａ（実施例１）に貯留された試験液Ａ，Ｂ，Ｃは、容器Ｂ（比較例１）に貯留された試験液Ａ，Ｂ，Ｃよりも、残存する有効塩素濃度がいずれも高く、実施例１の試験液Ａ、４０℃保存を除いて、初期濃度に対して９０％以上であった。
As is clear from Table 1, when compared under the same storage conditions, the test solutions A, B, and C stored in the container A (Example 1) are the test solutions A, stored in the container B (Comparative Example 1). The remaining effective chlorine concentration was higher than that of B and C, and was 90% or more of the initial concentration except for the test solution A of Example 1 stored at 40 ° C.
表２から明らかなように、容器Ｃ，Ｄ（実施例２，３）に貯留された試験液Ｄは、容器Ｅ，Ｆ，Ｇ（比較例２～４）に貯留されたいずれの試験液Ｄよりも、残存する有効塩素濃度が高かった。
As is clear from Table 2, the test liquid D stored in the containers C and D (Examples 2 and 3) is any of the test liquids D stored in the containers E, F and G (Comparative Examples 2 and 4). The remaining effective chlorine concentration was higher than that.
