Description
本発明は、薬剤取り替え時期表示具に関するものである。 The present invention relates to a medicine replacement time display tool.
従来から、含有する薬液の残量に応じて、表示面上に薬剤使用可能期間を示す形態のインジケーターが多々知られている。
例えば、特開２００３−３０２９０６号公報では、含有液体の揮散によって表示が発現するインジケーター用表示基板において、液体透過性を呈する基板材と、該基板材面上に部分的に積層され液体含有時に光に対し低屈折率を呈する形成材からなる複数の表示部と、各表示部の間を区切る基板材の液体不透過性部からなり、液体含有時に該表示部域の間で液体の移動が生じないことを特徴とする表示基板が提案されている。
2. Description of the Related Art Conventionally, there are many known indicators in a form that indicates a medicine usable period on a display surface in accordance with the remaining amount of chemical liquid contained.
For example, in Japanese Patent Application Laid-Open No. 2003-302906, in a display substrate for an indicator that displays by volatilization of a contained liquid, a substrate material exhibiting liquid permeability and a light that is partially laminated on the surface of the substrate material and contained when the liquid is contained. A plurality of display parts made of a forming material exhibiting a low refractive index, and a liquid-impermeable part of the substrate material separating each display part, and liquid movement occurs between the display part areas when liquid is contained. There has been proposed a display substrate characterized by the absence of the above.
また、特開２００８−７６６０７号公報には、少なくとも２つの視覚的に相異なる状態を呈する表示層を有してなるシート基材に液状物質が保持されてなる液状物質保持シート全体が、厚さ１０〜１００μｍのオレフィン系樹脂フィルムで被覆された期間表示器が記載されている。
特に後者の期間表示器は、シートをフィルムで被覆しているため屋外でも使用可能とされているが、具体的な実施例で用いられているフィルムの厚さは２０〜３０μｍと薄く、しかもシートがフィルムと密着しているので、風などの屋外条件が液状物質の揮散性に少なからず影響を及ぼすことが避けられない。更に、液状物質（エステル化合物）とオレフィン系樹脂フィルムとの親和性を考慮すると、取り替え時期が表示されるまでの期間の調節は、エステル化合物の種類や、フィルムの種類の変更を必要とし、種々の有効期間を有する薬剤揮散具に適用させるには、複雑なものとならざるを得なかった。
Japanese Patent Laid-Open No. 2008-76607 discloses that the entire liquid material holding sheet in which a liquid material is held on a sheet base material having a display layer that exhibits at least two visually different states has a thickness. A period indicator covered with a 10-100 μm olefinic resin film is described.
In particular, the latter period indicator can be used outdoors because the sheet is covered with a film, but the thickness of the film used in a specific embodiment is as thin as 20 to 30 μm, and the sheet Since the film is in close contact with the film, it is inevitable that outdoor conditions such as wind will affect the volatility of the liquid material. Furthermore, in consideration of the affinity between the liquid substance (ester compound) and the olefin resin film, the adjustment of the period until the replacement time is displayed requires a change in the type of ester compound and the type of film. In order to be applied to a chemical volatilization device having an effective period of, it has been complicated.
本発明は、薬剤揮散体の取り替え時期を示すための薬剤取り替え時期表示具であって、屋外での使用に際し風などの影響を受けにくく、しかも、薬液保持部材に含有される薬液添加量を変化させるだけで、各種の有効期間に対応して適用可能な薬剤取り替え時期表示具の提供を課題とする。 The present invention is a drug replacement time display tool for indicating the replacement time of the chemical volatilization body, and is less susceptible to wind during outdoor use, and also changes the amount of chemical solution added to the chemical solution holding member.

そして、本発明の薬剤取り替え時期表示具を用いることにより、薬剤揮散体の取り替え時期を正確に表示し、変更時期を使用者に伝えることが可能となる。
The present invention is not easily affected by wind or the like when used outdoors, and can be applied to various effective periods only by changing the amount of the chemical solution contained in the chemical solution holding member. Provide ingredients.
Then, by using the medicine replacement time display tool of the present invention, it is possible to accurately display the replacement time of the chemical volatilizer and to inform the user of the change time.
本発明の薬剤取り替え時期表示具は、主として屋外、屋外に近い屋内、玄関先などの場所で使用される薬剤揮散体に備えられるものである。ここで、薬剤揮散体とは、害虫防除剤や害虫の寄り付きを抑える虫除け剤などの薬剤を有するとともに、該薬剤を空中に放散する機能を備えた器具、装置等をいう。 The drug replacement time display tool of the present invention is provided in a drug volatilizer used mainly in places such as outdoors, indoors close to the outdoors, and entrances. Here, the chemical volatilization body refers to an instrument, an apparatus, or the like that has a pest control agent or a pest control agent that suppresses the contact of the pest and has a function of releasing the chemical into the air.
本発明の薬剤取り替え時期表示具は、表面に隠蔽層を有する基材にパラフィン系溶剤を添加した薬液保持部材をプラスチック製容器に入れ、この容器の上面を、厚さが７０〜２５０μｍの薬液透過性フィルムで被覆して構成される。
薬液保持部材に用いる基材としては、各種の材質のもの、例えば、通常の紙素材、パルプ紙、板紙、合成繊維混抄紙、不織布、織物、ポリオレフィン樹脂等が挙げられるが、なかでも、パラフィン系溶剤の吸液性に優れた紙又は不織布が好適である。
この基材の表面には、必要に応じて、各種の顔料や染料等を塗布あるいは印刷し、文字や絵柄などを表示したり、全面着色したりして色の変化をもたせ、視認性を高めることが出来る。
In the medicine replacement time indicator of the present invention, a chemical holding member in which a paraffinic solvent is added to a base material having a concealing layer on the surface is placed in a plastic container, and the upper surface of the container is permeated with a chemical liquid having a thickness of 70 to 250 μm. Covered with a conductive film.
Examples of the base material used for the chemical solution holding member include various materials, for example, ordinary paper materials, pulp paper, paperboard, synthetic fiber mixed paper, non-woven fabric, woven fabric, polyolefin resin, and the like. Paper or nonwoven fabric excellent in solvent absorbability is preferred.
As necessary, various pigments and dyes are applied or printed on the surface of the base material to display letters or pictures, or to color the entire surface to change the color, thereby improving visibility. I can do it.
上記基材の表面に塗工される隠蔽層としては、薬液が含有された時に透明に変性するものであればいずれも用いることが可能であるが、例えば、無定形シリカ、カオリン、炭酸カルシウム等の無機顔料、プラスチックピグメント微粉体等の有機顔料、あるいはこれらに種々のバインダーを混合したものなどを挙げることが出来る。 As the concealing layer applied to the surface of the base material, any one can be used as long as it is transparently modified when a chemical solution is contained. For example, amorphous silica, kaolin, calcium carbonate, etc. Inorganic pigments, organic pigments such as plastic pigment fine powder, and those obtained by mixing various binders with these.
本発明では、隠蔽層を塗工した基材に添加する薬液として、パラフィン系溶剤を用いることを第一の特徴とする。
特許文献２（特開２００８−７６６０７号公報）では、液状物質としてエステル化合物を用いているが、オレフィン系樹脂フィルムとの親和性の点から、取り替え時期が表示されるまでの期間の調節は、必ずしも満足のいくものでなかった。しかるに、本発明者らは、種々の薬液を検討した結果、パラフィン溶剤を用いることによって、薬液添加量を変化させるだけで各種の有効期間に対応可能な薬剤取り替え時期表示具の提供が可能となったものである。
パラフィン系溶剤としては、イソパラフィン及びノルマルパラフィンのいずれも使用可能であるが、特に、主留分の２０℃における蒸気圧が１×１０−４〜１×１０−１ｍｍＨｇのイソパラフィンは、粘度が低く、基材に対する拡散性にも優れており、性能的に好ましい。
かかるパラフィン系溶剤の具体例を示せば、アイソパーＭ（エクソンモービルケミカル社製、主留分の蒸気圧：８×１０−2ｍｍＨｇ）、アイソパーＶ（エクソンモービルケミカル社製、主留分の蒸気圧：４×１０−3ｍｍＨｇ）、ＩＰ２８３５（出光石油化学製、主留分の蒸気圧：３×１０−3ｍｍＨｇ）、デオトミゾール（三光化学工業製、主留分の蒸気圧：２×１０−2ｍｍＨｇ）等があげられるが、これらに限定されない。
The first feature of the present invention is that a paraffinic solvent is used as a chemical solution to be added to the base material coated with the concealing layer.
In Patent Document 2 (Japanese Patent Laid-Open No. 2008-76607), an ester compound is used as a liquid substance, but from the point of affinity with an olefin resin film, the adjustment of the period until the replacement time is displayed is It was not always satisfactory. However, as a result of studying various chemical solutions, the present inventors have been able to provide a drug replacement time display device that can cope with various effective periods only by changing the amount of the chemical solution added by using a paraffin solvent. It is a thing.
As the paraffinic solvent, both isoparaffin and normal paraffin can be used. In particular, isoparaffin having a main fraction with a vapor pressure of 1 × 10 −4 to 1 × 10 −1 mmHg at 20 ° C. has a low viscosity. Further, it is excellent in diffusibility with respect to the base material, which is preferable in terms of performance.
Specific examples of such paraffinic solvents include Isopar M (manufactured by ExxonMobil Chemical Co., vapor pressure of main fraction: 8 × 10 −2 mmHg), Isopar V (manufactured by ExxonMobil Chemical Co., Ltd., vapor pressure of main fraction) : 4 × 10 −3 mmHg), IP2835 (manufactured by Idemitsu Petrochemical, vapor pressure of main fraction: 3 × 10 −3 mmHg), deotomisole (manufactured by Sanko Chemical Co., Ltd., vapor pressure of main fraction: 2 × 10 −2) mmHg) and the like, but is not limited thereto.
本発明では、薬液保持部材がプラスチック製容器に収納して用いられることを第二の特徴とする。このため、薬液保持部材とフィルムは、特許文献２（特開２００８−７６６０７号公報）のように密着せず、後記するように、薬液保持部材とフィルム間に形成される適度な空間が、パラフィン系溶剤の揮散調整に役立つものである。
なお、本発明で用いるプラスチック製容器としては、通常の種々の材質のものが可能であり、例えば、ポリエチレン、ポリプロピレン、ポリエステル、ポリアミド、ポリアセタール、ポリアクリルニトリルなどがあげられる。なかんずく、材質としてポリエステルもしくはポリアミドを選択すると、薬液であるパラフィン系溶剤がプラスチック製容器に吸着されるのが極力抑えられ、かつ成形性も良好なので、本発明の目的に適している。
The second feature of the present invention is that the chemical solution holding member is housed in a plastic container. For this reason, the chemical solution holding member and the film do not adhere to each other as in Patent Document 2 (Japanese Patent Laid-Open No. 2008-76607). As described later, an appropriate space formed between the chemical solution holding member and the film is paraffin. This is useful for adjusting volatilization of solvent.
The plastic container used in the present invention can be made of various ordinary materials such as polyethylene, polypropylene, polyester, polyamide, polyacetal, polyacrylonitrile and the like. In particular, when polyester or polyamide is selected as the material, it is suitable for the purpose of the present invention because the paraffinic solvent which is a chemical solution is suppressed from being adsorbed to the plastic container as much as possible and the moldability is good.
本発明の第三の特徴は、前記プラスチック製容器の上面を、厚さが７０〜２５０μｍの薬液透過性フィルムで被覆したことにある。すなわち、特許文献２（特開２００８−７６６０７号公報）で用いられたオレフィン系樹脂フィルム（実施例での厚さ：２０〜３０μｍ）と異なり、厚さが７０〜２５０μｍの薬液透過性フィルムを採用することによって、パラフィン系溶剤の揮散が風などの影響を受けにくくなり、かつ揮散調整の面でも有利となった。
薬液透過性フィルムとしては、薬液透過性である限り使用可能で、例えば、ポリエチレン（超低密度ポリエチレン、低密度ポリエチレンや高密度ポリエチレン等）、ポリプロピレン等のポリオレフィン系樹脂フィルム、ポリスチレン、セルロース系樹脂フィルム等を例示できる。なかでも、ポリエチレン又はポリプロピレン製フィルムの場合、多種の中から所望の薬液透過性を有する仕様を選択できるので使いやすい。
A third feature of the present invention is that the upper surface of the plastic container is covered with a chemical-permeable film having a thickness of 70 to 250 μm. That is, unlike the olefin resin film (thickness in the example: 20 to 30 μm) used in Patent Document 2 (Japanese Patent Laid-Open No. 2008-76607), a chemical liquid permeable film having a thickness of 70 to 250 μm is adopted. As a result, the volatilization of the paraffinic solvent is less affected by wind and the like, and it is advantageous in terms of volatilization adjustment.
As a chemical liquid permeable film, it can be used as long as it is permeable to chemical liquids. For example, polyolefin resin films such as polyethylene (ultra low density polyethylene, low density polyethylene, high density polyethylene, etc.), polypropylene, polystyrene, and cellulose resin films. Etc. can be illustrated. In particular, in the case of a film made of polyethylene or polypropylene, it is easy to use because specifications having desired chemical liquid permeability can be selected from various types.
上記薬液透過性フィルムの上面側を更に薬液非透過性のフィルムで覆い、使用者が使用開始時に該薬液非透過性フィルムのみを剥がすように設計してもよい。かかる構成によれば、パラフィン系溶剤の揮散が常に使用開始時と同時にスタートすることになるので、交換時期のバラツキを小さくすることができる。
ここで用いられる薬液非透過性フィルムとしては、アルミフィルム（アルミ箔）、ポリエステルもしくはポリアミドフィルム等をあげることができ、なかでもアルミフィルムは、パラフィン系溶剤の薬液透過性フィルムからの揮散を完全に抑え、内部の薬液保持部材の表示機能に影響を生じさせないので好適である。
The upper surface side of the chemical liquid permeable film may be further covered with a chemical liquid impermeable film, and the user may design so that only the chemical liquid impermeable film is peeled off at the start of use. According to this configuration, since the volatilization of the paraffinic solvent always starts simultaneously with the start of use, the variation in the replacement time can be reduced.
Examples of the chemical-impermeable film used here include an aluminum film (aluminum foil), a polyester film, and a polyamide film. In particular, the aluminum film completely eliminates the volatilization of the paraffinic solvent from the chemical-permeable film. It is preferable because it suppresses and does not affect the display function of the internal chemical liquid holding member.
本発明の薬剤取り替え時期表示具では、前記したように、薬液保持部材と薬液透過性フィルム間に形成される適度な空間がパラフィン系溶剤の揮散調整に寄与する。このため、前記基材の体積（Ａ）と薬液透過性フィルム被覆後のプラスチック製容器内の体積（Ｂ）との比（Ａ／Ｂ）が、０．０５〜０．８、好ましくは０．１〜０．５となるように設計するのが良い。
この数値が小さいと薬剤取り替え時期表示具の使用開始前において、表示具の色むらが発生する可能性があり、一方、この数値が高すぎると、即ち、両者の密着性が高くなると、パラフィン系溶剤の薬液透過性フィルムからの揮散性に問題を生じ易い傾向がある。
In the medicine replacement time display tool of the present invention, as described above, an appropriate space formed between the chemical liquid holding member and the chemical liquid permeable film contributes to the volatilization adjustment of the paraffinic solvent. For this reason, the ratio (A / B) of the volume (A) of the base material and the volume (B) in the plastic container after coating with the chemical-permeable film is 0.05 to 0.8, preferably 0.8. It is good to design so that it may become 1-0.5.
If this value is small, color unevenness of the display device may occur before the start of use of the medicine replacement time display device. On the other hand, if this value is too high, that is, if the adhesion between the two becomes high, the paraffin type There is a tendency to cause a problem in the volatility of the solvent from the chemical-permeable film.
本発明は、このように、薬液保持部材に添加する薬液としてパラフィン系溶剤を選択し、薬液保持部材をプラスチック製容器に収納して用い、更にプラスチック製容器の上面を厚さが７０〜２５０μｍの薬液透過性フィルムで被覆したことを大きな特徴とする。
最良の実施形態としては、例えば、主留分の２０℃における蒸気圧が１×１０−3〜１×１０−2ｍｍＨｇであるイソパラフィンを添加した薬液保持部材を、Ａ／Ｂの比率が０．１〜０．５となるようにポリエステル製容器に入れ、この上面を厚さが１００〜１２０μｍの高密度ポリエチレンフィルムで覆った薬剤取り替え時期表示具があげられ、かかる組み合わせによれば、イソパラフィンの添加量と取り替え時期表示期間の相関性も良く、薬液添加量を変化させるだけで各種の有効期間に対応させることも容易となる。
As described above, the present invention selects a paraffinic solvent as a chemical solution to be added to the chemical solution holding member, uses the chemical solution holding member in a plastic container, and further uses the upper surface of the plastic container with a thickness of 70 to 250 μm. The main feature is that it is coated with a chemical-permeable film.
As the best embodiment, for example, a chemical holding member to which an isoparaffin having a vapor pressure of 1 × 10 −3 to 1 × 10 −2 mmHg at 20 ° C. of a main fraction is added, and the A / B ratio is set to 0.1. The drug replacement time indicator is put in a polyester container so as to be 1 to 0.5, and this upper surface is covered with a high-density polyethylene film having a thickness of 100 to 120 μm. The correlation between the amount and the replacement time display period is also good, and it becomes easy to correspond to various effective periods simply by changing the amount of the chemical solution added.
こうして得られた本発明の薬剤取り替え時期表示具は、害虫防除剤、害虫忌避剤、虫除け剤、ダニ防除剤、ダニ忌避剤、防カビ剤、消臭剤など、各種の機能を有する薬剤揮散体に備えられ、該機能を発揮する時期を示すためのインジケーターとして使用される。特に、屋外、屋外に近い屋内、玄関先など、風など環境の影響を受けやすい使用場面で有用性が高い。 The drug replacement time indicator of the present invention thus obtained is a pesticide, pest repellent, insect repellent, tick repellent, tick repellent, mold repellent, deodorant, etc. And is used as an indicator for indicating the time when the function is performed. In particular, it is highly useful in situations where it is susceptible to environmental influences such as wind, such as outdoors, indoors close to the outdoors, and front doors.
つぎに具体的実施例ならびに試験例に基づいて、本発明の薬剤取り替え時期表示具を更に詳細に説明するが、本発明はこれらに限定されるものではない。 Next, the drug replacement time display device of the present invention will be described in more detail based on specific examples and test examples, but the present invention is not limited to these.
パルプ紙基材（大きさ：１８×２２×１ｍｍ、体積Ａ：３９６ｍｍ3）の片面に緑色の顔料を星型に塗布後、更にその上に隠蔽層としてシリカと樹脂の混合物を塗工したものに、アイソパーＶ（イソパラフィン系溶剤、２０℃の蒸気圧：４×１０−3ｍｍＨｇ）５０ｍｇを添加して薬液保持部材を得た。塗工面を上にしてこの薬液保持部材を、内部が窪んだポリエステル製容器（体積Ｂ：１２４０ｍｍ3）に入れ、容器上面をポリエチレン製フィルム（厚さ：１００μｍ）で覆い、容器外周部をヒートシールして本発明の薬剤取り替え時期表示具を作製した。なお、Ａ／Ｂの体積比率は、０．３２であった。 A pulp paper base (size: 18 × 22 × 1 mm, volume A: 396 mm 3 ) coated with a green pigment in a star shape and then coated with a mixture of silica and resin as a concealing layer 50 mg of Isopar V (isoparaffinic solvent, vapor pressure at 20 ° C .: 4 × 10 −3 mmHg) was added to obtain a chemical holding member. Put this chemical holding member with the coating surface up in a polyester container (volume B: 1240 mm 3 ) with a hollow inside, cover the upper surface of the container with a polyethylene film (thickness: 100 μm), and heat seal the outer periphery of the container Thus, the medicine replacement time display tool of the present invention was produced. The volume ratio of A / B was 0.32.
メトフルトリン２００ｍｇを含有させた網状樹脂シート（７．５×１４．５ｃｍ×２面）をプラスチックケースに収納してなる虫除け用薬剤揮散体に、得られた本発明の薬剤取り替え時期表示具を装填した。
これを風通しの良いベランダの物干し竿に吊るして使用したところ、およそ６０日後、表示具の基材面に緑色の星型が現れ、使用の交換時期を示した。本品のインジケーター機能は屋外での使用にも拘わらず十分正確で使い易かった。
An insect repellent chemical volatilization product, in which a net-like resin sheet (7.5 × 14.5 cm × 2 sides) containing 200 mg of metfurthrin is housed in a plastic case, was loaded with the obtained drug replacement timing indicator of the present invention. .
When this was hung on a clothesline on a well-ventilated veranda, a green star appeared on the base material surface of the display device after about 60 days, indicating a replacement period for use. The indicator function of this product was sufficiently accurate and easy to use despite being used outdoors.
実施例１に準じて、表１に示す薬剤取り替え時期表示具を作製した。なお、プラスチック製容器の材質としてはポリエステル（ＰＥＴ）を用いた。 In accordance with Example 1, the drug replacement time indicator shown in Table 1 was prepared. Polyester (PET) was used as the material for the plastic container.
表１に示す薬剤取り替え時期表示具につき、以下の表示機能試験を行った。
［試験方法］
表示具を２５℃で、風速１ｍ／秒（及び風速０．３ｍ／秒）の条件に置き、経時的に表示具の退色を目視観察した。判定は、○：開始直後と変化なし、△：開始直後に較べて僅かに退色、×：完全に退色、で示し、終点の経過日数を表示期間とした。
The following display function tests were conducted for the drug replacement time display tools shown in Table 1.
[Test method]
The indicator was placed at 25 ° C. under conditions of a wind speed of 1 m / sec (and a wind speed of 0.3 m / sec), and the fading of the indicator was visually observed over time. Judgment is indicated by ○: immediately after the start and no change, Δ: slightly fading compared to immediately after the start, ×: completely fading, and the elapsed days of the end point is defined as the display period.
試験の結果、本発明の薬剤取り替え時期表示具は、風などの環境条件の影響をあまり受けず所定の時期に取り替えの表示時期を示し、良好な表示性能であった。また、本発明１と本発明２の対比から、薬液保持部材に含有される薬液添加量を変化させるだけで、各種の表示期間に対応できることが認められ、極めて有用かつ実用的であることが実証された。
これに対し、薬液としてイソプロパノールを用いた比較例１では、薬液の添加後直ぐに退色してしまい、表示具として不適当であった。また、比較例２や比較例３のように、パラフィン系溶剤以外の薬液である、ミリスチン酸イソプロピルやパルミチン酸イソプロピルを用いた場合、退色時期が非常に遅れるとともに退色の時期が明瞭でなく、本発明の趣旨に合致しなかった。なお、ミリスチン酸イソプロピルを、特許文献２（特開２００８−７６６０７号公報）に準じて、厚みが２０μｍのポリエチレンフィルムに密着させた構成（比較例４）では、薬液の揮散に伴って表示機能を奏したものの、風の影響が避けられず、性能的に満足のいくものとは言えなかった。この傾向は、本発明で用いるパラフィン系溶剤の場合（比較例５）も同様で、従って、薬液保持部材に添加する薬液としてパラフィン系溶剤を選択したうえで、薬液保持部材をプラスチック製容器に収納して用い、更にプラスチック製容器の上面を厚さが７０〜２５０μｍの薬液透過性フィルムで被覆することによってはじめて、本発明が目的とする表示性能を奏し得ることが明らかである。
As a result of the test, the drug replacement time display tool of the present invention was not affected by environmental conditions such as wind so much and showed a replacement display time at a predetermined time and showed a good display performance. Further, it is recognized from the comparison between the present invention 1 and the present invention 2 that it is possible to cope with various display periods only by changing the amount of the chemical solution contained in the chemical solution holding member, and it is proved that it is extremely useful and practical. It was done.
On the other hand, in Comparative Example 1 using isopropanol as the chemical solution, the color fading immediately after the addition of the chemical solution, which is inappropriate as a display device. Further, as in Comparative Example 2 and Comparative Example 3, when using isopropyl myristate or isopropyl palmitate, which is a chemical solution other than a paraffinic solvent, the fading time is very delayed and the fading time is not clear. It did not meet the gist of the invention. In addition, according to patent document 2 (Unexamined-Japanese-Patent No. 2008-76607), the structure (comparative example 4) which made isopropyl myristate contact | adhere to the 20-micrometer-thick polyethylene film has a display function with volatilization of a chemical | medical solution. Although played, the influence of the wind was unavoidable, and it could not be said that the performance was satisfactory. This tendency is the same in the case of the paraffinic solvent used in the present invention (Comparative Example 5). Therefore, after selecting the paraffinic solvent as the chemical solution to be added to the chemical solution holding member, the chemical solution holding member is stored in the plastic container. It is apparent that the display performance intended by the present invention can be achieved only when the upper surface of the plastic container is further covered with a chemical-permeable film having a thickness of 70 to 250 μm.
本発明の薬剤取り替え時期表示具は、害虫防除剤、害虫忌避剤、虫除け剤、ダニ防除剤、ダニ忌避剤、防カビ剤、消臭剤、芳香剤、抗菌剤など、有効成分を揮散させるあらゆるタイプの各種製品に適用可能である。
The drug replacement time display device of the present invention is a pest control agent, pest repellent, insect repellent, tick repellent, mite repellent, fungicide, deodorant, fragrance, antibacterial agent, etc. Applicable to various types of products.
