　本発明は、例えば芳香剤や消臭剤などの揮発性薬剤を揮散可能に封入した薬剤揮散袋、およびこれを収納する薬剤揮散容器に関する。


The present invention relates to a drug volatilization bag in which a volatile drug such as a fragrance or a deodorant is encapsulated, and a drug volatilization container for storing the drug volatilization bag.





　従来、芳香剤や消臭剤を部屋などに拡散させる用途に使用するものとして、例えば特許文献１に開示されたものがある。


Conventionally, as what is used for the use which diffuses a fragrance | flavor or a deodorant in a room etc., there exists what was disclosed by patent document 1, for example.





　この特許文献１で開示された芳香剤包装体は、内面がヒートシール性を有し、ガス遮断性フィルム層を含む多層フィルムからなり、開放端部が内容物入り袋を強く押圧することにより容易に破袋し得る程度に剥離容易な強度でシールされた内包装用袋内に揮発性芳香剤が充填密封され、その芳香剤が充填密封された内包装用袋が、ガス透過性フィルムからなる外包装用袋で密封包装されたものである（特許文献１の図２参照）。


The fragrance package disclosed in this Patent Document 1 has a heat seal property on the inner surface and is made of a multilayer film including a gas barrier film layer, and the open end portion easily presses the bag containing the contents easily. A volatile fragrance is filled and sealed in an inner packaging bag that is sealed to such an extent that it can be peeled easily, and the inner packaging bag that is filled and sealed with the fragrance is made of a gas permeable film. It is sealed and packaged with a packaging bag (see FIG. 2 of Patent Document 1).





　この芳香剤包装体を使用するに際しては、外部から外包装用袋を介して内包装用袋を押圧することにより、その外力による内圧上昇でもって内包装用袋のシール部が破袋して外包装用袋内に芳香剤が流出する。この外包装用袋は、ガス透過性フィルムで構成されていることから、外包装用袋内に流出した芳香剤は、ガス透過性フィルムを通して外部へ揮散するようになっている。


When using this fragrance package, the inner packaging bag is pressed from the outside through the outer packaging bag, and the inner pressure of the inner packaging bag is increased by the external force. The fragrance flows out into the packaging bag. Since this outer packaging bag is made of a gas permeable film, the fragrance that has flowed into the outer packaging bag is volatilized to the outside through the gas permeable film.





実公昭６０－１７３０号公報Japanese Utility Model Publication No. 60-1730



　ところで、前述の特許文献１で開示された芳香剤包装体では、外包装用袋の外部へ芳香剤を揮散させるため、その外包装用袋の両面をガス透過性フィルムで構成している。しかしながら、芳香剤の種類によっては、芳香剤を外包装用袋から揮散させることが困難となる場合がある。具体的には、従来のポリエチレン等のガス透過性フィルムは、芳香剤を構成する香料の主成分であるリナロールやジヒドロミルセノール等のアルコールの透過性が悪く、揮散を制限することがあった。


By the way, in the fragrance packaged body disclosed in the above-mentioned Patent Document 1, in order to volatilize the fragrance to the outside of the outer packaging bag, both surfaces of the outer packaging bag are constituted by gas permeable films. However, depending on the type of fragrance, it may be difficult to volatilize the fragrance from the outer packaging bag. Specifically, conventional gas-permeable films such as polyethylene have poor permeability to alcohols such as linalool and dihydromyrsenol, which are the main components of the fragrance constituting the fragrance, and may limit volatilization. .





　つまり、芳香剤に用いる香料には多種の成分が存在し、化学的性質も多種に亘る。また、外包装用袋を構成するガス透過性フィルムについても、その素材によってガス透過度が異なる。そのため、芳香剤とガス透過性フィルムとの馴染みがよく、芳香剤を外包装用袋から良好に揮散させ得る芳香剤とガス透過性フィルムとの組み合わせを選定しなければならない。その結果、外包装用袋を構成するガス透過性フィルムに対して、使用可能な芳香剤が制約されるという問題があった。


That is, the fragrance | flavor used for a fragrance | flavor has a various component, and its chemical property is also various. Also, the gas permeability of the gas permeable film constituting the outer packaging bag varies depending on the material. Therefore, the familiarity between the fragrance and the gas permeable film is good, and a combination of the fragrance and the gas permeable film that can vaporize the fragrance from the outer packaging bag must be selected. As a result, there is a problem that usable fragrances are restricted with respect to the gas permeable film constituting the outer packaging bag.





　そこで、本発明は前述の問題点に鑑みて提案されたもので、その目的とするところは、芳香剤や消臭剤などの揮発性薬剤を使用する上でその選択の自由度を向上させ得る薬剤揮散袋及びこれを収納する薬剤揮散容器を提供することにある。


Therefore, the present invention has been proposed in view of the above-described problems, and the object of the present invention is to improve the degree of freedom of selection when using volatile agents such as fragrances and deodorants. It is in providing a chemical volatilization bag and a chemical volatilization container which stores this.





　前述の目的を達成するための技術的手段として、本発明に係る薬剤揮散袋は、ガス非透過性フィルムで形成され、内部に揮発性薬剤が封入された軟質の内側袋体と、その内側袋体を収容する軟質の外側袋体とを備え、内側袋体は、外力による内圧上昇で破袋可能に構成され、外側袋体は、一面とこれに対向する他面とを有し、少なくとも一面は、揮発性薬剤が浸潤可能な多数の微孔を有する微多孔質シートで構成されていることを特徴とする。


As a technical means for achieving the above-mentioned object, a drug volatilization bag according to the present invention is formed of a gas non-permeable film, a soft inner bag body in which a volatile drug is enclosed, and the inner bag. A soft outer bag body that accommodates the body, the inner bag body is configured to be capable of breaking the bag by an increase in internal pressure due to an external force, and the outer bag body has one surface and another surface facing the at least one surface. Is characterized in that it is composed of a microporous sheet having a large number of micropores into which a volatile drug can infiltrate.





　ここで、外側袋体の少なくとも一面を構成する微多孔質シートとは、分子レベルで揮発性薬剤のガスを透過させるガス透過性フィルムと異なり、揮発性薬剤が浸潤してシート表面に滲み出る程度に多数の微孔が物理的に形成されたものを意味する。また、外側袋体の他面は、前述の微多孔質シートで構成する以外に、例えば、揮発性薬剤が浸潤不能なシートで構成することも可能である。この揮発性薬剤が浸潤しないシートとしては、分子レベルで揮発性薬剤のガスを透過させるガス透過性フィルムや、揮発性薬剤のガスを遮断するガス非透過性フィルムが適用可能である。このように、外側袋体の他面を構成するシートの素材は任意である。


Here, the microporous sheet constituting at least one surface of the outer bag body is different from a gas permeable film that allows a gas of a volatile drug to permeate at a molecular level, so that the volatile drug infiltrates and oozes on the sheet surface. Means that a large number of micropores are physically formed. In addition, the other surface of the outer bag body can be formed of, for example, a sheet that cannot be infiltrated with a volatile drug, in addition to the above-described microporous sheet. As the sheet in which the volatile drug does not infiltrate, a gas permeable film that allows the gas of the volatile drug to permeate at a molecular level or a gas impermeable film that blocks the gas of the volatile drug can be applied. Thus, the material of the sheet constituting the other surface of the outer bag body is arbitrary.





　本発明の薬剤揮散袋では、外力による内圧上昇で内側袋体が破袋すると、その内側袋体に封入されていた揮発性薬剤が外側袋体内に流出する。この外側袋体は、その少なくとも一面が揮発性薬剤が浸潤可能な多数の微孔を有する微多孔質シートで構成されていることから、外側袋体内に流出した揮発性薬剤は、微多孔質シートの微孔でもって浸潤してシート表面に滲み出ることにより外部へ揮散する。


In the drug volatilization bag of the present invention, when the inner bag breaks due to an increase in internal pressure due to external force, the volatile drug sealed in the inner bag flows out into the outer bag. Since the outer bag body is composed of a microporous sheet having at least one surface that has a large number of micropores into which the volatile drug can infiltrate, the volatile drug that has flowed into the outer bag body is a microporous sheet. Volatilizes to the outside by infiltrating through the micropores and exuding on the sheet surface.





　このように、外側袋体の少なくとも一面を構成する微多孔質シートは、揮発性薬剤が浸潤してシート表面に滲み出る程度に多数の微孔が物理的に形成されたものであることから、従来のガス透過性フィルムと異なり、化学的性質が多種に亘る揮発性薬剤との組み合わせを選定する必要がなく、使用可能な揮発性薬剤が多種に亘り、揮発性薬剤を外側袋体から容易に揮散させることができる。このように、外側袋体の少なくとも一面を構成する微多孔質シートに対して、使用可能な揮発性薬剤が制約されることがないので、揮発性薬剤を使用する上でその選択の自由度を向上させることができる。


Thus, since the microporous sheet constituting at least one surface of the outer bag body is one in which a large number of micropores are physically formed to such an extent that the volatile drug infiltrates and exudes to the sheet surface, Unlike conventional gas permeable films, there is no need to select a combination of volatile chemicals with a wide variety of chemical properties, there are a wide variety of volatile chemicals that can be used, and volatile chemicals can be easily removed from the outer bag. Can be stripped. In this way, the volatile chemicals that can be used are not restricted with respect to the microporous sheet constituting at least one surface of the outer bag, so that the degree of freedom in selecting the volatile chemicals can be increased. Can be improved.





　この微多孔質シートは、揮発性薬剤が多数の微孔でもって浸潤してシート表面に滲み出ることから、ガス透過性フィルムと比較しても揮発性薬剤の揮散量も多くなり、揮発性薬剤を外側袋体から良好に揮散させることができる。そのため、必ずしも外側袋体の両面を微多孔質シートで構成する必要はなく、少なくとも外側袋体の一面を微多孔質シートで構成すれば十分である。


In this microporous sheet, the volatile agent infiltrates with a large number of micropores and oozes out on the surface of the sheet. Therefore, the volatilization amount of the volatile agent is larger than that of the gas permeable film. Can be volatilized well from the outer bag. Therefore, it is not always necessary to configure both sides of the outer bag body with the microporous sheet, and it is sufficient that at least one surface of the outer bag body is configured with the microporous sheet.





　また、本発明に係る薬剤揮散容器は、前述の薬剤揮散袋が収納され、内側袋体と対応する部位に、外側袋体を介して内側袋体に外力を付与する押圧部が設けられたケースとで構成されていることを特徴とする。この薬剤揮散容器においては、微多孔質シートで構成された外側袋体の一面を上側に向けて薬剤揮散袋を配置した状態でケースを被取付け部材に装着することが望ましい。


The drug volatilization container according to the present invention is a case in which the above-mentioned drug volatilization bag is accommodated and a pressing portion for applying an external force to the inner bag body via the outer bag body is provided at a site corresponding to the inner bag body. It is comprised by these. In this chemical volatilization container, it is desirable to attach the case to the member to be attached in a state where the chemical volatilization bag is arranged with one surface of the outer bag body made of a microporous sheet facing upward.





　本発明の薬剤揮散容器を使用するに際しては、ケースに収納された薬剤揮散袋に対して、ケースの押圧部を押し込むことにより、薬剤揮散袋の外側袋体を介して内側袋体に外力を付与する。この外力の付与により内側袋体の内圧が上昇し、その内圧上昇でもって内側袋体が破袋する。この内側袋体の破袋により、内側袋体に封入されていた揮発性薬剤が外側袋体内に流出する。この外側袋体内に流出した揮発性薬剤は、微多孔質シートの微孔でもって浸潤してシート表面に滲み出ることにより外部へ揮散する。


When using the chemical volatilization container of the present invention, an external force is applied to the inner bag body via the outer bag body of the chemical volatilization bag by pushing the pressing part of the case against the chemical volatilization bag stored in the case. To do. By applying this external force, the internal pressure of the inner bag increases, and the inner bag breaks with the increase of the internal pressure. Due to the inner bag body breaking, the volatile drug sealed in the inner bag body flows out into the outer bag body. The volatile chemicals that have flowed into the outer bag body infiltrate through the micropores of the microporous sheet and ooze out to the surface of the sheet to evaporate to the outside.





　この薬剤揮散容器の使用形態としては、薬剤揮散袋を縦置き状態でケース内に配置する場合と、薬剤揮散袋を横置き状態でケース内に配置する場合が可能である。特に、薬剤揮散袋を横置き状態でケース内に配置する薬剤揮散容器の使用形態では、前述したように、微多孔質シートで構成された外側袋体の一面を上側に向けて薬剤揮散袋を配置すれば、微多孔質シートの多数の微孔により浸潤してシート表面に滲み出た揮発性薬剤が液滴となってケース内部あるいはケース外部へ落下することを抑制できる。


As a usage form of this chemical volatilization container, it is possible to arrange the chemical volatilization bag in the case in a vertically placed state and to arrange the chemical volatilization bag in the case in a laterally placed state. In particular, in the usage form of the chemical volatilization container in which the chemical volatilization bag is placed horizontally in the case, as described above, the chemical volatilization bag is directed with the one side of the outer bag body composed of the microporous sheet facing upward. If it arrange | positions, it can suppress that the volatile chemical | medical agent which infiltrated by many micropores of the microporous sheet and oozed out on the sheet | seat surface becomes a droplet, and falls to the inside of a case or the case outside.





　本発明によれば、外側袋体は、その少なくとも一面が揮発性薬剤が浸潤可能な多数の微孔を有する微多孔質シートで構成されていることから、この微多孔質シートは、従来のガス透過性フィルムと異なり、化学的性質が多種に亘る揮発性薬剤との組み合わせを選定する必要がなく、使用可能な揮発性薬剤が多種に亘り、揮発性薬剤を外側袋体から容易に揮散させることができる。このように、外側袋体の少なくとも一面を構成する微多孔質シートに対して、使用可能な揮発性薬剤が制約されることがないので、揮発性薬剤を使用する上でその選択の自由度を向上させることができる。その結果、様々な用途に対して容易かつ迅速に対応できる薬剤揮散袋および薬剤揮散容器を実現することができる。


According to the present invention, at least one surface of the outer bag is composed of a microporous sheet having a large number of micropores that can be infiltrated with a volatile drug. Unlike permeable films, there is no need to select a combination with volatile chemicals that have a wide variety of chemical properties, and there are many types of volatile chemicals that can be used. Can do. In this way, the volatile chemicals that can be used are not restricted with respect to the microporous sheet constituting at least one surface of the outer bag, so that the degree of freedom in selecting the volatile chemicals can be increased. Can be improved. As a result, it is possible to realize a drug volatilization bag and a drug volatilization container that can easily and quickly respond to various uses.

　本発明に係る薬剤揮散袋およびこれを収納する薬剤揮散容器の実施形態を以下に詳述する。以下の実施形態では、ごみ箱の芳香剤として、ごみ箱の蓋の内側に装着する場合を例示するが、ごみ箱の芳香剤以外に、部屋や車内などの芳香剤あるいは消臭剤としても適用可能である。


Embodiments of a drug volatilization bag and a drug volatilization container for storing the drug volatilization bag according to the present invention will be described in detail below. In the following embodiment, as an example of a trash box fragrance, a case where it is attached to the inside of a trash box lid is illustrated, but in addition to a trash box fragrance, it can also be applied as a fragrance or deodorant in a room or a car interior. .





　図１～図４は薬剤揮散袋１１を例示し、図１は組立分解斜視図、図２は組立完了斜視図、図３は図２のＡ－Ａ線に沿う断面図、図４は使用状態の断面図である。この薬剤揮散袋１１は、図１～図３に示すように、軟質の内側袋体１２と、その内側袋体１２を収容する軟質の外側袋体１３とを備えた二重構造となっている。なお、図３および図４では、内側袋体１２および外側袋体１３の厚みや内部空間を誇張して示している。


1 to 4 exemplify the chemical volatilization bag 11, FIG. 1 is an exploded perspective view, FIG. 2 is a perspective view of completion of assembly, FIG. 3 is a cross-sectional view taken along the line AA in FIG. FIG. As shown in FIGS. 1 to 3, the chemical volatilization bag 11 has a double structure including a soft inner bag body 12 and a soft outer bag body 13 that accommodates the inner bag body 12. . 3 and 4, the thickness and the internal space of the inner bag body 12 and the outer bag body 13 are exaggerated.





　平面視矩形状の内側袋体１２は、透明なガス非透過性フィルム１４で袋状に形成され、内部に揮発性薬剤１５が封入されている。この内側袋体１２の素材であるガス非透過性フィルム１４としては、例えば、ポリエステル、ポリアミド、エチレン‐酢酸ビニル共重合体ケン化物、変性ポリビニルアルコール、ポリ塩化ビニリデン等の熱可塑性合成樹脂又はアルミニウム等の金属箔の１つ以上を含む多層積層材料がある。また、揮発性薬剤１５としては、揮発性香料を含む薬剤として、例えば、パラフィン系炭化水素、グリコールエーテル類、グリコール類、アルコール類、エステル類、ケトン類、ラクトン類、アルデヒド類等が使用可能である。また、揮発性薬剤は液体に限らず、固体状、ゲル状、ゾル状、またはこれらの混合物であってもよい。この揮発性薬剤１５を着色しておけば、内側袋体１２が透明フィルム１４で形成されていることから、外部から揮発性薬剤１５を目視確認することが容易となる。また、揮発性薬剤１５には増粘剤によって粘性を持たせても良い。増粘剤としては、グリセリン、糖脂肪酸エステル、蝋、増粘多糖類、カラギーナン、鉱物、金属石鹸、長鎖脂肪酸、長鎖脂肪酸の多価金属塩、アミノ酸誘導体、糖の誘導体等が例示される。


The inner bag body 12 having a rectangular shape in plan view is formed into a bag shape with a transparent gas-impermeable film 14, and a volatile drug 15 is enclosed therein. Examples of the gas non-permeable film 14 that is the material of the inner bag 12 include thermoplastic synthetic resins such as polyester, polyamide, saponified ethylene-vinyl acetate copolymer, modified polyvinyl alcohol, and polyvinylidene chloride, and aluminum. There are multilayer laminate materials comprising one or more of the following metal foils. Moreover, as the volatile chemical | medical agent 15, paraffin type hydrocarbons, glycol ethers, glycols, alcohols, ester, ketones, lactones, aldehydes etc. can be used as a chemical | medical agent containing a volatile fragrance | flavor, for example. is there. Further, the volatile drug is not limited to a liquid, and may be a solid, gel, sol, or a mixture thereof. If this volatile chemical | medical agent 15 is colored, since the inner side bag body 12 is formed with the transparent film 14, it will become easy to visually confirm the volatile chemical | medical agent 15 from the outside. Further, the volatile drug 15 may be made viscous by a thickener. Examples of the thickener include glycerin, sugar fatty acid ester, wax, thickening polysaccharide, carrageenan, mineral, metal soap, long chain fatty acid, polyvalent metal salt of long chain fatty acid, amino acid derivative, sugar derivative and the like. .





　内側袋体１２は、一枚のガス非透過性フィルム１４を二つ折りし、その開口する三つの辺部１６をヒートシールで熱融着することにより袋状としている。この三つの辺部１６は、外力による内圧上昇で破袋可能な強度でシールされている。その場合、破袋可能にシールする辺部１６の数および箇所は任意である。また、この内側袋体１２では、一枚のガス非透過性フィルム１４を二つ折りにして三つの辺部１６を破袋可能にシールしているが、二枚のガス非透過性フィルム１４を重ね合わせることにより袋状とすることも可能であり、その場合、破袋可能にシールする辺部１６の数および箇所も任意である。


The inner bag body 12 is formed into a bag shape by folding a single gas-impermeable film 14 in two and heat-sealing the three side portions 16 that are opened by heat sealing. The three side portions 16 are sealed with such a strength that can be broken by an increase in internal pressure due to an external force. In that case, the number and location of the side portions 16 to be sealed so as to be broken are arbitrary. Further, in this inner bag body 12, one gas impermeable film 14 is folded in two and the three side portions 16 are sealed so as to be able to break the bag, but the two gas impermeable films 14 are overlapped. It is also possible to form a bag by combining them, and in that case, the number and location of the side portions 16 to be sealed so as to be broken are arbitrary.





　また、平面視矩形状の外側袋体１３は、一面を構成する一枚の微多孔質シート１７と、これに対向する他面を構成する一枚の透明シート１８とを重ね合わせ、その開口する四つの辺部１９をヒートシールで熱融着することにより袋状としている。なお、微多孔質シート１７は、外側袋体１３の一面の全体を構成する以外に、一面の一部分を構成するようにしてもよい。外側袋体１３の四つの辺部１９は、内側袋体１２の場合と異なり、外力による内圧上昇で破袋しないようにシールされている。この外側袋体１３の他面側を透明シート１８で構成することにより、この他面側から内側袋体１２および揮発性薬剤１５を目視確認することが容易となる。なお、この実施形態では、外側袋体１３の他面を透明シート１８で構成した場合について説明するが、この外側袋体１３の他面を構成するシートは必ずしも透明である必要はなく、非透明や半透明であってもよいし、微多孔質シートであっても構わない。


In addition, the outer bag 13 having a rectangular shape in plan view overlaps one microporous sheet 17 that constitutes one surface and one transparent sheet 18 that constitutes the other surface opposite thereto, and opens. The four side portions 19 are heat-sealed by heat sealing to form a bag shape. The microporous sheet 17 may constitute a part of one surface other than the entire surface of the outer bag 13. Unlike the case of the inner bag body 12, the four side portions 19 of the outer bag body 13 are sealed so as not to break the bag due to an increase in internal pressure due to an external force. By configuring the other surface side of the outer bag body 13 with the transparent sheet 18, it becomes easy to visually check the inner bag body 12 and the volatile chemical 15 from the other surface side. In addition, although this embodiment demonstrates the case where the other surface of the outer bag 13 is comprised with the transparent sheet 18, the sheet | seat which comprises the other surface of this outer bag 13 does not necessarily need to be transparent, and is non-transparent. Alternatively, it may be translucent or a microporous sheet.





　外側袋体１３の一面を構成する微多孔質シート１７は、揮発性薬剤１５が浸潤可能な多数の微孔を有する。つまり、揮発性薬剤１５のガスを透過させるガス透過性フィルムと異なり、揮発性薬剤１５が浸潤してシート表面に滲み出る程度に多数の微孔が物理的に形成されている。この微多孔質シート１７としては、例えば、高密度ポリエチレン、中密度ポリエチレン、低密度ポリエチレン、直鎖状低密度ポリエチレン、超高分子量ポリエチレン等の各種ポリエチレンや、エチレン‐酢酸ビニル共重合体およびそのケン化物、エチレン‐アクリル系共重合体、エチレン‐プロピレン共重合体、種々のオレフィン系樹脂およびその共重合体、ジエン系樹脂およびその共重合体、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリカーボネート、ポリスチレン、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリカーボネート、ポリウレタン、各種アクリル系樹脂、ポリビニルアルコール、ポリイミド、フッ素樹脂、シリコン樹脂、エポキシ樹脂、セロハン等の半合成樹脂などがある。この微多孔質シート１７に用いられる樹脂は、単体で用いてもよく、共重合体、ブレンド物などとして用いてもよい。さらには前述の樹脂を複数用いて多層にした多層シートとしてもよい。多層シートとするためには、ドライラミネーションや共押出し、押出ラミネーションなどの公知の手段によって行われる。シートに成型するにあたり種々の添加物を混練したり、成型後に延伸や熱処理などを行ってもまったく差し支えない。成型後にコーティング、蒸着などを行ってもよい。シートが２層以上になっている場合に、そのうち１層が金属箔もしくは金属蒸着膜、もしくは無機蒸着膜層であってもよい。


The microporous sheet 17 constituting one surface of the outer bag 13 has a large number of micropores into which the volatile drug 15 can be infiltrated. That is, unlike the gas permeable film that allows the gas of the volatile drug 15 to pass therethrough, a large number of micropores are physically formed to such an extent that the volatile drug 15 infiltrates and oozes out on the sheet surface. Examples of the microporous sheet 17 include various polyethylenes such as high-density polyethylene, medium-density polyethylene, low-density polyethylene, linear low-density polyethylene, and ultra-high molecular weight polyethylene, ethylene-vinyl acetate copolymer, and ken , Ethylene-acrylic copolymers, ethylene-propylene copolymers, various olefin resins and their copolymers, diene resins and their copolymers, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, polystyrene, polychlorinated Examples include vinyl, polyvinylidene chloride, polycarbonate, polyurethane, various acrylic resins, polyvinyl alcohol, polyimide, fluorine resin, silicon resin, epoxy resin, and semisynthetic resin such as cellophane. The resin used for the microporous sheet 17 may be used alone or as a copolymer or a blend. Furthermore, it is good also as a multilayer sheet which made the above-mentioned resin into multiple layers. In order to obtain a multilayer sheet, it is carried out by known means such as dry lamination, co-extrusion, and extrusion lamination. In molding into a sheet, various additives may be kneaded, or stretching or heat treatment may be performed after molding. You may perform coating, vapor deposition, etc. after shaping | molding. When the sheet has two or more layers, one of them may be a metal foil, a metal vapor deposition film, or an inorganic vapor deposition film layer.





　外側袋体１３の他面を構成する透明シート１８は、揮発性薬剤１５が浸潤不能なシートである。つまり、前述の微多孔質シート１７とは異なり、揮発性薬剤１５が浸潤しない。この揮発性薬剤１５が浸潤しない透明シート１８は、分子レベルで揮発性薬剤１５のガスを透過させるガス透過性フィルムと、揮発性薬剤１５のガスを遮断するガス非透過性フィルムのいずれであってもよい。このガス非透過性フィルムとしては、前述の内側袋体１２で使用した素材から選択され得るものを使用すればよい。また、ガス透過性フィルムとしては、例えば、ポリエチレン、ポリプロピレン、エチレン‐酢酸ビニル共重合樹脂、アイオノマー樹脂、エチレン‐アクリル酸共重合樹脂、エチレン‐αオレフィン共重合樹脂等の熱可塑性樹脂の１つ以上を含む多層積層材料がある。


The transparent sheet 18 constituting the other surface of the outer bag 13 is a sheet that cannot be infiltrated by the volatile drug 15. That is, unlike the aforementioned microporous sheet 17, the volatile drug 15 does not infiltrate. The transparent sheet 18 that does not infiltrate the volatile drug 15 is either a gas permeable film that allows the gas of the volatile drug 15 to permeate at a molecular level or a gas non-permeable film that blocks the gas of the volatile drug 15. Also good. As the gas non-permeable film, a film that can be selected from the materials used in the inner bag 12 described above may be used. Examples of the gas permeable film include one or more thermoplastic resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer resin, ionomer resin, ethylene-acrylic acid copolymer resin, and ethylene-α-olefin copolymer resin. There are multi-layer laminate materials comprising





　以上で説明した構成からなる薬剤揮散袋１１では、図４に示すように、外力（図中白抜き矢印参照）の作用により内側袋体１２の内圧が上昇し、シールされた三つの辺部１６が開封して内側袋体１２が破袋すると、その内側袋体１２に封入されていた揮発性薬剤１５が外側袋体１３内に流出する。この外側袋体１３は、その一面（図中上面）が揮発性薬剤１５が浸潤可能な多数の微孔を有する微多孔質シート１７で構成されていることから、外側袋体１３内に流出した揮発性薬剤１５は、微多孔質シート１７の微孔でもって浸潤してシート表面に滲み出ることにより外部へ揮散する（図中破線矢印参照）。


In the drug volatilization bag 11 having the above-described configuration, as shown in FIG. 4, the internal pressure of the inner bag body 12 is increased by the action of an external force (see the white arrow in the figure), and the three sides 16 sealed are sealed. When the inner bag body 12 is broken, the volatile drug 15 enclosed in the inner bag body 12 flows into the outer bag body 13. Since the outer bag 13 is composed of a microporous sheet 17 having one side (upper surface in the figure) having a large number of micropores into which the volatile drug 15 can infiltrate, the outer bag 13 flows into the outer bag 13. The volatile chemical 15 infiltrates through the micropores of the microporous sheet 17 and oozes out to the surface of the sheet, and then volatilizes to the outside (see the broken line arrow in the figure).





　このように、外側袋体１３の一面を構成する微多孔質シート１７は、揮発性薬剤１５が浸潤してシート表面に滲み出る程度に多数の微孔が物理的に形成されたものであることから、従来のガス透過性フィルムと異なり、化学的性質が多種に亘る揮発性薬剤１５との組み合わせを選定する必要がなく、使用可能な揮発性薬剤１５が多種に亘り、揮発性薬剤１５を外側袋体１３から容易に揮散させることができる。このように、外側袋体１３の一面を構成する微多孔質シート１７に対して、使用可能な揮発性薬剤１５が制約されることがないので、揮発性薬剤１５を使用する上でその選択の自由度を向上させることができる。


As described above, the microporous sheet 17 constituting one surface of the outer bag body 13 is one in which a large number of micropores are physically formed to such an extent that the volatile drug 15 infiltrates and exudes to the sheet surface. Therefore, unlike the conventional gas permeable film, it is not necessary to select a combination with the volatile agent 15 having various chemical properties, and there are various types of volatile agents 15 that can be used. It can be easily volatilized from the bag 13. Thus, since the usable volatile chemical | medical agent 15 is not restrict | limited with respect to the microporous sheet | seat 17 which comprises one surface of the outer side bag body 13, when using the volatile chemical | medical agent 15, the selection of that is possible. The degree of freedom can be improved.





　この微多孔質シート１７は、揮発性薬剤１５が多数の微孔でもって浸潤してシート表面に滲み出ることから、ガス透過性フィルムと比較しても揮発性薬剤１５の揮散量も多くなり、揮発性薬剤１５を外側袋体１３から良好に揮散させることができる。そのため、外側袋体１３の両面を微多孔質シート１５で構成する必要はなく、外側袋体１３の一面のみを微多孔質シート１５で構成すればよい。その結果、外側袋体１３の他面は、ガス透過性フィルムあるいはガス非透過性フィルム等のように、揮発性薬剤１５が浸潤不能なシートで構成すればよい。


This microporous sheet 17 infiltrates the volatile agent 15 with a large number of micropores and oozes out on the surface of the sheet, so that the volatilization amount of the volatile agent 15 increases even when compared with the gas permeable film, The volatile chemical 15 can be volatilized well from the outer bag 13. Therefore, it is not necessary to configure both surfaces of the outer bag 13 with the microporous sheet 15, and only one surface of the outer bag 13 may be configured with the microporous sheet 15. As a result, the other surface of the outer bag 13 may be formed of a sheet that cannot be infiltrated by the volatile drug 15 such as a gas permeable film or a gas non-permeable film.





　以上で説明した薬剤揮散袋１１をごみ箱の芳香剤として使用する場合、その薬剤揮散袋１１をプラスチック等の樹脂製ケース２１に収納した薬剤揮散容器として使用する。図５～図１０はケース２１を例示し、図５は二つのケース半体２３，２４を衝合させた二分割構造のケース２１を例示し、（Ａ）は上面図、（Ｂ）は正面図、（Ｃ）は下面図、図６は図５（Ａ）のＢ－Ｂ線に沿う断面図、図７は一方のケース半体２３（以下、上ケースと称す）の下面図、図８は図７のＣ－Ｃ線に沿う断面図、図９は他方のケース半体２４（以下、下ケースと称す）の上面図、図１０は図９のＤ－Ｄ線に沿う断面図である。


When the chemical volatilization bag 11 described above is used as a fragrance for a trash box, the chemical volatilization bag 11 is used as a chemical volatilization container housed in a resin case 21 such as plastic. 5 to 10 illustrate a case 21, FIG. 5 illustrates a case 21 having a two-part structure in which two case halves 23 and 24 are abutted, (A) is a top view, and (B) is a front view. FIG. 6C is a bottom view, FIG. 6 is a sectional view taken along line BB in FIG. 5A, FIG. 7 is a bottom view of one case half 23 (hereinafter referred to as the upper case), and FIG. Is a cross-sectional view taken along the line CC of FIG. 7, FIG. 9 is a top view of the other case half 24 (hereinafter referred to as the lower case), and FIG. 10 is a cross-sectional view taken along the line DD of FIG. .





　このケース２１は、図５（Ａ）～（Ｃ）および図６に示すように、二つの円形皿状の上下ケース２３，２４を衝合させた二分割構造をなしている。このケース２１は、使用済みの薬剤揮散袋１１が交換可能なように、図７および図８に示す上ケース２３と、図９および図１０に示す下ケース２４のそれぞれの外周部位に以下のような構造を設けている。上ケース２３のピン２５を下ケース２４の凹孔２６に挿入する構造でもって上下ケース２３，２４が位置合わせ可能となっており、また、上ケース２３の爪２７と下ケース２４の爪２８を引っ掛け係止する構造により上下ケース２３，２４がワンタッチ式で分離可能な嵌合構造となっている。このケース２１では、爪２７，２８同士の引っ掛け係止構造により分離可能な嵌合構造としているが、ヒンジ構造により開閉可能とすることにより、使用済みの薬剤揮散袋１１を交換可能とするようにしてもよい。


As shown in FIGS. 5A to 5C and FIG. 6, the case 21 has a two-part structure in which two circular dish-like upper and lower cases 23 and 24 are abutted. The case 21 has the following outer peripheral portions of the upper case 23 shown in FIGS. 7 and 8 and the lower case 24 shown in FIGS. 9 and 10 so that the used medicine volatilization bag 11 can be replaced as follows. The structure is provided. The upper and lower cases 23, 24 can be aligned with a structure in which the pin 25 of the upper case 23 is inserted into the concave hole 26 of the lower case 24, and the claw 27 of the upper case 23 and the claw 28 of the lower case 24 are The upper and lower cases 23 and 24 can be separated by a one-touch type by a hooking and locking structure. In this case 21, the fitting structure is separable by a hooking and locking structure between the claws 27 and 28, but the used medicine volatilization bag 11 can be exchanged by making the hinge structure openable and closable. May be.





　上ケース２３には、その中央部位に、薬剤揮散袋１１の内側袋体１２に外側袋体１３を介して外力を付与する円形の押圧部２９が設けられている。この押圧部２９は、可撓性を有する連結部３０を介して上ケース２３に片持ち支持された状態で一体的に形成され、上ケース２３の開口部３１に配置されて押し込み可能となっている。この押圧部２９の円周方向周囲には、揮発性薬剤１５の薬剤ガスを放出させるための複数の揮散孔３２が開口している。また、この上ケース２３には、上下ケース２３，２４の衝合時に、下ケース２４に位置決め載置された薬剤揮散袋１１の外側袋体１３の四隅部３３（図９参照）を下ケース２４の内側へ押し込む四つの押し込みリブ３４が、外側袋体１３の四隅部３３と対応する部位に一体的に形成されている。


The upper case 23 is provided with a circular pressing portion 29 that applies an external force to the inner bag body 12 of the drug volatilization bag 11 via the outer bag body 13 at the central portion thereof. The pressing portion 29 is integrally formed in a state where it is cantilevered and supported by the upper case 23 via a flexible connecting portion 30 and can be pushed in by being disposed in the opening 31 of the upper case 23. Yes. Around the circumferential direction of the pressing portion 29, a plurality of volatilization holes 32 for releasing the drug gas of the volatile drug 15 are opened. Further, the upper case 23 is provided with four corners 33 (see FIG. 9) of the outer bag body 13 of the drug volatilization bag 11 positioned and placed on the lower case 24 when the upper and lower cases 23 and 24 meet. Four pushing ribs 34 to be pushed inwardly are integrally formed at portions corresponding to the four corners 33 of the outer bag 13.





　下ケース２４には、薬剤揮散袋１１の外側袋体１３が載置される四つの支持リブ３５が一体的に立設されている。また、外側袋体１３の各辺部１９に当接することにより外側袋体１３を位置規制する四つの位置規制リブ３６が一体的に立設されている。この位置規制リブ３６の先端部は鉤状をなし、その鉤状先端部で外側袋体１３を押さえ込むことで外側袋体１３の浮きを防止して位置規制の安定化を図っている。この下ケース２４の中央部位には、押圧部２９により外力が付与された薬剤揮散袋１１の内側袋体１２を外側袋体１３を介して支持する受け部３７が一体的に設けられている。この受け部３７は、押し込み動作させた押圧部２９と薬剤揮散袋１１を介して正対するように傾斜した支持面３８を有する。受け部３７は、内側円形リブ３９と外側円形リブ４０の二重構造をなし、その支持面３８は、内側円形リブ３９およびその内側に位置する十字形リブ４１と外側円形リブ４０の上端部で構成されている。


The lower case 24 is integrally provided with four support ribs 35 on which the outer bag 13 of the chemical volatilization bag 11 is placed. In addition, four position regulating ribs 36 that integrally position the outer bag body 13 by being in contact with the side portions 19 of the outer bag body 13 are erected integrally. The front end portion of the position restricting rib 36 has a hook shape, and the outer bag body 13 is pressed by the hook-shaped front end portion to prevent the outer bag body 13 from floating, thereby stabilizing the position restriction. A receiving portion 37 that supports the inner bag body 12 of the drug volatilization bag 11 to which an external force is applied by the pressing portion 29 via the outer bag body 13 is integrally provided at the central portion of the lower case 24. The receiving portion 37 has a support surface 38 that is inclined so as to face the pressing portion 29 that has been pushed in, and the medicine volatilization bag 11. The receiving portion 37 has a double structure of the inner circular rib 39 and the outer circular rib 40, and the support surface 38 is at the upper end portion of the inner circular rib 39 and the cross-shaped rib 41 and the outer circular rib 40 located inside thereof. It is configured.





　なお、下ケース２４の外側中央部位には、薬剤揮散容器２２をごみ箱の蓋の内側に取り付けるための粘着テープ４２が設けられている。この下ケース２４には、揮散孔３２が設けられていない。この下ケース２４には、薬剤揮散容器２２をごみ箱の蓋の内側に取り付けるための粘着テープ４２が取り付けられているため、下ケース２４に揮散孔３２がないことにより、使用時に薬剤揮散袋１１から揮散する揮発性薬剤１５でもって、下ケース２４に近接配置された粘着テープ４２の粘着力を低下させたり、ごみ箱の蓋の素材を傷めることを防止できるようにしている。


In addition, an adhesive tape 42 for attaching the drug volatilization container 22 to the inner side of the lid of the trash box is provided at the outer central portion of the lower case 24. The lower case 24 is not provided with a volatilization hole 32. Since the adhesive tape 42 for attaching the chemical volatilization container 22 to the inner side of the lid of the trash box is attached to the lower case 24, the lower case 24 has no volatilization hole 32. The volatile chemical 15 that volatilizes can prevent the adhesive force of the adhesive tape 42 disposed in the vicinity of the lower case 24 from being lowered, and prevent the material of the lid of the trash can from being damaged.





　以上で説明したケース２１に前述の薬剤揮散袋１１を装填する要領を、図１１～図１３を参照しながら以下に詳述する。図１１～図１３は前述のケース２１に薬剤揮散袋１１を組み付けた薬剤揮散容器２２を例示し、図１１および図１２は組立分解斜視図、図１３は組立完了斜視図である。


The procedure for loading the above-described drug volatilization bag 11 into the case 21 described above will be described in detail below with reference to FIGS. FIGS. 11 to 13 exemplify the drug volatilization container 22 in which the drug volatilization bag 11 is assembled to the above-described case 21, FIG. 11 and FIG. 12 are exploded perspective views, and FIG.





　下ケース２４の支持リブ３５上に矩形状の薬剤揮散袋１１をその外側袋体１３の微多孔質シート１７が下ケース２４側に向くように載置すると共に、その薬剤揮散袋１１の各辺部１９を位置規制リブ３６に側方から当接させることにより、薬剤揮散袋１１を位置決めする。この薬剤揮散袋１１が位置決め載置された下ケース２４に、上ケース２３を上ケース２３のピン２５および下ケース２４の凹孔２６からなる構造でもって位置合わせすると共に上ケース２３の爪２７と下ケース２４の爪２８との引っ掛け係止構造でもって嵌合させる。このようにして、薬剤揮散袋１１のケース２１への組み付けを完了する。


The rectangular drug volatilization bag 11 is placed on the support rib 35 of the lower case 24 so that the microporous sheet 17 of the outer bag 13 faces the lower case 24 side, and each side of the drug volatilization bag 11 is placed. The chemical volatilization bag 11 is positioned by bringing the portion 19 into contact with the position regulating rib 36 from the side. The upper case 23 is aligned with the lower case 24 on which the medicine volatilization bag 11 is positioned and placed with a structure including the pin 25 of the upper case 23 and the concave hole 26 of the lower case 24, and the claw 27 of the upper case 23 The lower case 24 is fitted with a hook and lock structure with the claw 28. In this way, the assembly of the chemical volatilization bag 11 to the case 21 is completed.





　この上下ケース２３，２４の衝合時、下ケース２４に位置決め載置された薬剤揮散袋１１の外側袋体１３の四隅部３３は、上下ケース２３，２４の外周部上あるいはその近傍に位置するため（図９参照）、上下ケース２３，２４の外周部間で噛み込んだり、その外周部から食み出したりする可能性がある。そこで、上ケース２３に設けられた押し込みリブ３４により、上下ケース２３，２４の衝合時に薬剤揮散袋１１の外側袋体１３の四隅部３３を下ケース２４の内側へ押し込むようにしている。これにより、薬剤揮散袋１１の外側袋体１３の四隅部３３が上下ケース２３，２４の外周部間に噛み込んだり、その外周部から食み出したりすることを未然に防止し、この噛み込みや食み出しにより外側袋体１３が破れて揮発性薬剤１５が外部へ漏洩することを回避している。


When the upper and lower cases 23 and 24 meet, the four corners 33 of the outer bag 13 of the drug volatilization bag 11 positioned and placed on the lower case 24 are positioned on or near the outer peripheral portions of the upper and lower cases 23 and 24. For this reason (see FIG. 9), there is a possibility that the upper and lower cases 23 and 24 may be bitten between the outer peripheral portions or protrude from the outer peripheral portions. Therefore, the pushing ribs 34 provided on the upper case 23 push the four corners 33 of the outer bag 13 of the chemical volatilization bag 11 into the lower case 24 when the upper and lower cases 23 and 24 meet. This prevents the four corners 33 of the outer bag 13 of the chemical volatilization bag 11 from being caught between the outer peripheral parts of the upper and lower cases 23, 24 and protruding from the outer peripheral parts. This prevents the outer bag 13 from being torn and leaking the volatile drug 15 to the outside due to protrusion.





　以上で説明した薬剤揮散容器２２をごみ箱の芳香剤として使用する場合、図１４および図１５に示すように、下ケース２４に設けられた粘着テープ４２を利用し、薬剤揮散容器２２を被取付け部材であるごみ箱４３の蓋４４の内側に貼着する。つまり、薬剤揮散容器２２は、上ケース２３が下向きで下ケース２４が上向きとなる上下逆さ状態で取り付けられる。この取り付け状態では、薬剤揮散容器２２が略水平状態に保持され、薬剤揮散容器２２内に収納された薬剤揮散袋１１は、微多孔質シート１７を上側に向けた状態で保持される。一方、この薬剤揮散容器２２をごみ箱４３の蓋４４に取り付ける前あるいは取り付けた後に、次の操作により薬剤揮散袋１１の内側袋体１２を破袋する。


When the chemical volatilization container 22 described above is used as a fragrance for a trash can, as shown in FIGS. 14 and 15, the adhesive tape 42 provided on the lower case 24 is used to attach the chemical volatilization container 22 to a member to be attached. It sticks inside the lid 44 of the trash box 43. That is, the chemical volatilization container 22 is attached in an upside down state in which the upper case 23 faces downward and the lower case 24 faces upward. In this attached state, the drug volatilization container 22 is held in a substantially horizontal state, and the drug volatilization bag 11 accommodated in the drug volatilization container 22 is held with the microporous sheet 17 facing upward. On the other hand, before or after attaching the chemical volatilization container 22 to the lid 44 of the trash box 43, the inner bag 12 of the chemical volatilization bag 11 is broken by the following operation.





まず、薬剤揮散容器２２の上ケース２３に設けられた押圧部２９を容器内部へ押し込むことにより、薬剤揮散袋１１の外側袋体１３を介して内側袋体１２に外力を付与する。この外力の付与により内側袋体１２の内圧が上昇し、その内圧上昇でもって内側袋体１２が破袋する。この内側袋体１２の破袋は、三つの辺部１６が外力による内圧上昇で破袋可能な強度でシールされていることから、この三つの辺部１６の一部または全部が開口することにより行われる。


First, an external force is applied to the inner bag body 12 via the outer bag body 13 of the drug volatilization bag 11 by pushing the pressing portion 29 provided in the upper case 23 of the drug volatilization container 22 into the container. By applying this external force, the internal pressure of the inner bag body 12 is increased, and the inner bag body 12 is broken by the increase of the internal pressure. Since the three side portions 16 are sealed with such a strength that the inner bag body 12 can be broken by an increase in internal pressure due to external force, a part or all of the three side portions 16 are opened. Done.





　この押圧部２９による外力の付与時、図１６に示すように、上ケース２３に連結部３０を介して設けられた押圧部２９は、その連結部３０が可撓性を有することから、連結部３０の撓みにより容器内部へ押し込まれる。この押圧部２９の押し込み動作により、薬剤揮散袋１１が下ケース２４の受け部３７と押圧部２９との間に挟み込まれる。この押し込み動作により傾斜する押圧部２９に対して、内側円形リブ３９および十字形リブ４１と外側円形リブ４０からなる受け部３７の支持面３８が薬剤揮散袋１１を介して正対するように傾斜していることから、押圧部２９の押圧面４５と受け部３７の支持面３８が平行となるので、押圧部２９の全面で薬剤揮散袋１１に接触する。


When the external force is applied by the pressing portion 29, as shown in FIG. 16, the pressing portion 29 provided on the upper case 23 via the connecting portion 30 has the connecting portion 30 having flexibility. It is pushed into the container by the bending of 30 Due to the pressing operation of the pressing portion 29, the drug volatilization bag 11 is sandwiched between the receiving portion 37 of the lower case 24 and the pressing portion 29. The support surface 38 of the receiving portion 37 composed of the inner circular rib 39 and the cross-shaped rib 41 and the outer circular rib 40 is inclined so as to face the pressing portion 29 inclined by the pushing operation through the drug volatilization bag 11. Therefore, since the pressing surface 45 of the pressing part 29 and the support surface 38 of the receiving part 37 are parallel, the entire surface of the pressing part 29 contacts the drug volatilization bag 11.





　このように、押圧部２９と薬剤揮散袋１１との接触面積を最大限に確保することができるので、押圧部２９により十分な外力を付与することができ、薬剤揮散袋１１の内側袋体１２を確実に破袋させることができる。また、上ケース２３の押圧部２９と下ケース２４の受け部３７とからなり、薬剤揮散袋１１の外部に位置するケース２１に設けられた簡単な構造でもって、内側袋体１２を破袋させることができる。


Thus, since the contact area of the press part 29 and the medicine volatilization bag 11 can be ensured to the maximum, a sufficient external force can be applied by the press part 29, and the inner bag body 12 of the drug volatilization bag 11. Can be surely broken. In addition, the inner bag body 12 is broken with a simple structure including the pressing portion 29 of the upper case 23 and the receiving portion 37 of the lower case 24 and provided in the case 21 located outside the drug volatilization bag 11. be able to.





　この内側袋体１２の破袋により、図１７に示すように、内側袋体１２に封入されていた揮発性薬剤１５が外側袋体１３内に流出する。この外側袋体１３は、上側に向く一面を揮発性薬剤１５が浸潤可能な多数の微孔を有する微多孔質シート１７で構成していることから、外側袋体１３内に流出した揮発性薬剤１５は、微多孔質シート１７の微孔でもって浸潤してシート表面に滲み出ることにより外部へ揮散する。外側袋体１３の外部へ揮散した揮発性薬剤１５は、薬剤揮散容器２２の上ケース２３に設けられた揮散孔３２および開口部３１を介して容器外部へ放出させる。このようにして、容器外部へ揮散した揮発性薬剤１５をごみ箱４３の内部に充満させることにより、薬剤揮散容器２２がごみ箱４３の芳香剤として機能する。


As the inner bag body 12 is broken, the volatile drug 15 enclosed in the inner bag body 12 flows into the outer bag body 13 as shown in FIG. Since the outer bag 13 is composed of a microporous sheet 17 having a large number of micropores into which the volatile drug 15 can infiltrate, the volatile drug that has flowed into the outer bag 13. 15 is volatilized to the outside by infiltrating through the micropores of the microporous sheet 17 and oozing out onto the sheet surface. Volatile medicine 15 volatilized outside the outer bag 13 is released to the outside of the container through a volatilization hole 32 and an opening 31 provided in the upper case 23 of the chemical volatilization container 22. In this way, by filling the inside of the trash box 43 with the volatile chemical 15 volatilized to the outside of the container, the chemical volatilization container 22 functions as the fragrance of the trash box 43.





　なお、薬剤揮散袋１１の内側袋体１２に封入された揮発性薬剤１５を着色しておけば、外側袋体１３の上ケース２３側に向く面が透明シート１８で構成されていることから、外側袋体１３に流出した揮発性薬剤１５を上ケース２３の揮散孔３２および開口部３１から目視することができるので、揮発性薬剤１５の残量を確認することが容易となる。その結果、薬剤揮散容器２２が使い捨ての場合、その薬剤揮散容器２２の廃棄時期を迅速かつ容易に認知することができる。また、薬剤揮散容器２２が詰め替え可能な場合、薬剤揮散袋１１の交換時期を迅速かつ容易に認知することができる。　


In addition, if the volatile chemical | medical agent 15 enclosed with the inner side bag body 12 of the chemical volatilization bag 11 is colored, since the surface which faces the upper case 23 side of the outer side bag body 13 is comprised with the transparent sheet 18, Since the volatile chemical | medical agent 15 which flowed out to the outer side bag body 13 can be visually observed from the volatilization hole 32 and the opening part 31 of the upper case 23, it becomes easy to confirm the residual amount of the volatile chemical | medical agent 15. As a result, when the chemical volatilization container 22 is disposable, the disposal timing of the chemical volatilization container 22 can be recognized quickly and easily. Moreover, when the chemical volatilization container 22 can be refilled, the replacement time of the chemical volatilization bag 11 can be recognized quickly and easily.



　また、薬剤揮散袋１１は軟質の内側袋体１２および外側袋体１３で構成されていることから、揮発性薬剤１５の揮散によりその揮発性薬剤１５が減少しても、揮発性薬剤１５の減少に伴う内部減圧でもって外側袋体１３の微多孔質シート１７が揮発性薬剤１５に密着している。このように、微多孔質シート１７と揮発性薬剤１５との間に空気層ができずに微多孔質シート１７と揮発性薬剤１５とが常に接触していることから、揮発性薬剤１５がなくなるまで、その揮発性薬剤１５が微多孔質シート１７に浸潤してシート表面に滲み出るので、揮発性薬剤１５が減少せずに薬剤揮散袋１１に残存することを回避できる。


Further, since the chemical volatilization bag 11 is composed of the soft inner bag body 12 and the outer bag body 13, even if the volatile chemical agent 15 is reduced by the volatilization of the volatile chemical agent 15, the volatile chemical agent 15 is reduced. The microporous sheet 17 of the outer bag 13 is in close contact with the volatile chemical 15 by the internal pressure reduction accompanying the above. As described above, since the air layer is not formed between the microporous sheet 17 and the volatile agent 15 and the microporous sheet 17 and the volatile agent 15 are always in contact with each other, the volatile agent 15 is eliminated. Until that time, the volatile chemical | medical agent 15 infiltrates the microporous sheet | seat 17, and oozes out on the sheet | seat surface, Therefore It can avoid that the volatile chemical | medical agent 15 remains in the chemical volatilization bag 11 without reducing.





　以上で説明した薬剤揮散容器２２の使用形態では、ごみ箱４３の芳香剤としてごみ箱４３の蓋４４の内側に薬剤揮散袋１１を水平状態で保持した状態、いわゆる横置き状態にしている。このように、薬剤揮散袋１１を横置き状態でケース２１内に配置する薬剤揮散容器２２の使用形態では、前述したように、微多孔質シート１７で構成された外側袋体１３の一面を上側に向けて薬剤揮散袋１１を配置することにより、微多孔質シート１７の多数の微孔により浸潤してシート表面に滲み出た揮発性薬剤１５が液滴となってケース内部あるいはケース外部へ落下することを抑制できる。


In the usage form of the chemical volatilization container 22 described above, the chemical volatilization bag 11 is held in a horizontal state inside the lid 44 of the waste bin 43 as a fragrance of the waste bin 43, that is, in a so-called horizontal state. As described above, in the usage form of the drug volatilization container 22 in which the drug volatilization bag 11 is placed in the case 21 in the horizontal state, as described above, one surface of the outer bag body 13 constituted by the microporous sheet 17 is set on the upper side. By disposing the chemical volatilization bag 11 toward the surface, the volatile chemical 15 infiltrated by a large number of micropores in the microporous sheet 17 and oozing out onto the surface of the sheet falls into the case or outside the case. Can be suppressed.
