Abstract
Description
本発明は、モーターやゼンマイ等を使用せず、外部から受ける空気の移動によって薬剤を揮散させる薬剤揮散具に関するものである。 The present invention relates to a drug volatilization tool that volatilizes a drug by the movement of air received from the outside without using a motor or a spring.
害虫、例えば蚊や蚋などを駆除するために、薬剤を閉鎖空間（建築物や自動車の室内、アウトドアスポーツにおけるテント内など）全体に揮散、放出させる薬剤揮散方法として、熱エネルギーを利用した蚊取線香や電気蚊取マット、液体式電気蚊取（リキッド）が一般的である。一方、電源として乾電池を用い、薬剤含浸体にファン等の風をあてて常温で薬剤を揮散、放出させるファン式薬剤揮散装置も携帯用として実用化され、これに関する特許出願も多い。例えば、特開平７−１１１８５０号公報は、薬剤含浸体として積層段ボールを用いたファン式殺虫・防虫方法を開示するものであるが、当然のことながらファンを回転させるモーターとその駆動用電源を必要とし、積層段ボールの仕様はファンによる一定の風向きを前提としている。 In order to eliminate pests such as mosquitoes and moths, mosquito traps that use thermal energy are used as a chemical vaporization method that volatilizes and releases chemicals throughout closed spaces (such as buildings and automobile interiors and outdoor sports tents). Incense sticks, electric mosquito mats, and liquid electric mosquito traps (liquids) are common. On the other hand, a fan-type chemical volatilization apparatus that uses a dry battery as a power source and volatilizes and releases a chemical at room temperature by applying a fan or the like to the drug-impregnated body has been put into practical use for portable purposes, and there are many patent applications related to this. For example, Japanese Patent Application Laid-Open No. 7-111850 discloses a fan-type insecticide / insect control method using laminated cardboard as a drug impregnated body, but naturally requires a motor for rotating the fan and a power source for driving the fan. The specifications of the laminated cardboard are based on the premise that the fan has a constant wind direction.
ところで、ファンを具備せず、空中に浮遊もしくは吊り下げて薬剤を揮散させようとする提案もある。例えば、特開平１１−２５５６０４号公報に揮散性薬剤を風船基材に保持させてなる防虫材が記載されているが、自然に浮遊させるのみなので薬剤の放散力が十分と言えない。また、特開２０００−２４７８０６号公報には、揮散性薬剤を保持した担体を有する通気性構造体を吊り下げ、好ましくはこの通気性構造体に空中推進手段を備えた薬剤拡散装置が開示されている。しかしながら、この装置は、実質的にモーターやゼンマイ等の駆動装置を具備し、また、担体の材質や使用する殺虫成分等との関係について何の検討もされていないことから、長期間にわたり満足のいく揮散性能や害虫防除効果を示し得なかった。
本発明は、モーターやゼンマイ等の駆動装置を必要としない簡単な構造で、外部から受ける空気の移動のみで薬剤を揮散させ、しかも長期間にわたり優れた害虫防除効果を奏する段ボール積層型の薬剤揮散具を提供することを目的とする。 The present invention has a simple structure that does not require a driving device such as a motor or a spring, and volatilizes the drug only by the movement of air received from the outside, and also exhibits a pest control effect over a long period of time, and exhibits a superior pest control effect. The purpose is to provide ingredients.

常温揮散性防虫成分の担持量は、通気性担体の材質、使用場所、使用期間などを考慮し３０〜５００ｍｇの範囲で適宜決定される。防虫成分の担持量が３０ｍｇより少ないと、害虫防除効力の持続性に不足を生じる場合があり、一方５００ｍｇを超えても使用期間が必要以上に延長されるだけで格別のメリットはない。
常温揮散性防虫成分を通気性担体に担持させるに際しては、必要に応じ溶剤、希釈剤、界面活性剤、分散剤、徐放化剤などを用い、従来から知られている各種処理手段を採用することができる。もちろん、あらかじめ防虫成分を担持させた段ボール片を積層して薬剤担持体を形成するようにしてもよい。また、前記防虫成分に、安定剤、香料、着色剤、帯電防止剤などを適宜配合してもよく、更に、防虫成分の揮散性能に支障をきたさない限りにおいて、揮散性の高い他の殺虫、忌避成分（例えば、ディート、ヒノキチオール、カルボン、サフロール、シトロネラール、ケイ皮アルデヒドなどの防虫香料など）、殺ダニ剤、殺菌剤、消臭剤などを添加して多目的組成物とすることもできる。

The carrying amount of the room temperature volatile insect repellent component is appropriately determined in the range of 30 to 500 mg in consideration of the material of the breathable carrier, the place of use, the period of use, and the like. If the amount of the insect repellent component is less than 30 mg, the sustainability of the pest control effect may be insufficient. On the other hand, if it exceeds 500 mg, the period of use is only extended more than necessary, and there is no particular merit.
When carrying a room temperature volatile insect repellent component on a breathable carrier, a solvent, a diluent, a surfactant, a dispersant, a sustained release agent, etc. are used as necessary, and various conventionally known processing means are adopted. be able to. Of course, the medicine carrier may be formed by laminating cardboard pieces on which an insect repellent component is carried in advance. In addition, stabilizers, fragrances, colorants, antistatic agents and the like may be appropriately blended with the insect repellent component, and, as long as the volatilization performance of the insect repellent component is not hindered, other highly insecticidal insecticides, Repellent ingredients (for example, insect repellents such as diet, hinokitiol, carvone, safrole, citronellal, and cinnamic aldehyde), acaricides, bactericides, deodorants and the like can be added to form a multipurpose composition.
In addition, it is also possible to carry | support the coloring agent interlock | cooperated with the amount of room temperature volatile insecticide components on a breathable support | carrier, and to utilize as an indicator which shows the completion | finish of volatilization of an insecticide component.
本発明の薬剤揮散具は、モーターやゼンマイ等の駆動装置を具備しない簡単な構造で、しかも外部から受ける空気の移動のみで薬剤を揮散させるべく、通気性担体の構造を段ボール片積層型とし、かつ段ボールの波板の貫通穴の向きを１段毎もしくは数段毎に縦横交互させたことに特徴を有する。
すなわち、通常自然蒸散においては薬剤の放散力は不足するが、貫通穴の向きを縦横交互に設定することによって、薬剤担持体の周囲に空気の撹乱を生じ薬剤の拡散に寄与することが認められた。また、自然環境下では風向きは絶えず変化するものの、本発明の構成によれば、この風向きの変化にも関わらず薬剤担持体から薬剤が安定して揮散し、特定の常温揮散性防虫成分の防虫活性と相まって、十分な害虫防除効果を奏しえる。
The chemical volatilization tool of the present invention has a simple structure without a driving device such as a motor or a spring, and the breathable carrier structure is a corrugated piece laminated type in order to volatilize the chemical only by movement of air received from the outside, And the direction of the through-hole of the corrugated board of a corrugated cardboard has the characteristics in which the direction was alternated every one step or every several steps.
In other words, although natural transpiration usually lacks the ability to disperse the drug, it is recognized that by alternately setting the direction of the through holes in the vertical and horizontal directions, air is disturbed around the drug carrier and contributes to the diffusion of the drug. It was. In addition, although the wind direction constantly changes in the natural environment, according to the configuration of the present invention, the drug is stably volatilized from the drug carrier regardless of the change in the wind direction, and the insect repellent of a specific room temperature volatile insect repellent component Combined with the activity, it can have a sufficient pest control effect.
本発明において、段ボール片は平板と波板を貼り合わせたものを構成単位とし、上述のとおり、これを積層して通気性担体を形成する。
好ましい形態は、波板の高さが３〜１０ｍｍ、波板のピッチが３〜１０ｍｍ、波板の貫通穴の奥行きが２〜７ｃｍの段ボールを用い、かつ波板の貫通穴の向きが１段毎もしくは数段毎に縦横交互するように２０〜４０段積層して通気性担体を形成したものである。
通常、薬剤の揮散量を高めるために、通気性担体の総表面積を大きくする手段を採用するが、本発明の薬剤揮散具は揮散効率にすぐれるため、平板と延伸した波板の表面積の合計を、２００ｃｍ2〜２０００ｃｍ2程度に設計すれば十分である。また、通気性担体を複数個のブロックに分け、それぞれを紐で連結するようにして構成したものであっても構わない。
In the present invention, the corrugated board piece is a unit obtained by laminating a flat plate and a corrugated plate, and as described above, these are laminated to form a breathable carrier.
A preferred form uses corrugated cardboard with corrugated plate height of 3 to 10 mm, corrugated plate pitch of 3 to 10 mm, corrugated through hole depth of 2 to 7 cm, and corrugated through hole orientation of one step. A breathable carrier is formed by laminating 20 to 40 stages so as to alternate vertically and horizontally every few stages.
Usually, in order to increase the volatilization amount of the drug, a means for increasing the total surface area of the breathable carrier is adopted, but since the drug volatilization tool of the present invention is excellent in volatilization efficiency, the total surface area of the flat plate and the stretched corrugated plate is used. a, it is sufficient to design to about 200cm 2 ~2000cm 2. Further, the breathable carrier may be divided into a plurality of blocks, and each may be connected with a string.
段ボール片の材質は特に限定されないが、紙製のものが一般的である。各種プラスチック樹脂を混入して強度を高めたり、薬剤の揮散性を調節することもでき、このようなプラスチック樹脂として、ポリエチレンやポリプロピレンなどのポリオレフィン、ポリウレタン、ポリエステル、ポリカーボネ―ト、ポリスチレン、ポリ酢酸ビニール、エチレン酢酸ビニルコポリマーなどをあげることができる。
いずれの場合においても、常温揮散性防虫成分の揮散終了後、新しい薬剤担持体と交換し使用を継続すればよい。
The material of the corrugated cardboard piece is not particularly limited, but is generally made of paper. Various plastic resins can be mixed to increase the strength and the volatility of the chemicals can be adjusted. Polyolefins such as polyethylene and polypropylene, polyurethane, polyester, polycarbonate, polystyrene, polyvinyl acetate can be used as such plastic resins. And ethylene vinyl acetate copolymer.
In any case, after volatilization of the room temperature volatile insect repellent component is completed, it may be replaced with a new drug carrier and used continuously.
こうして得られた本発明の薬剤揮散具は、モーターやゼンマイ等の駆動装置を必要としない簡単な構造で、外部から受ける空気の移動、例えばエアーコンディショナー、扇風機のエアーや、窓を通して入り込む風を利用して、段ボール片積層型の薬剤担持体から防虫成分を揮散させる。なお、薬剤担持体に人の指などが触れないように、薬剤担持体を通気性のカートリッジに収納するようにしてもよい。
薬剤担持体からの防虫成分揮散量は、使用場所や風力等にもよるが、１時間当たり０．０１〜０．５ｍｇ程度であり、例えば通常の６畳の居住部屋で十分な害虫防除効果を奏する。ここで、害虫防除効果とは致死に至る殺虫作用を必然とせず、蚊に対する刺咬阻止、忌避作用を含めた広義の防虫効果を意味する。
かかる本発明の成果は、本発明で用いる常温揮散性防虫成分が従来のエムペントリンに比べて蒸気圧が幾分低いものの極めて高い基礎殺虫活性を有することを踏まえ、段ボール片積層型の材質や構造等との組み合わせを種々検討して初めて得られたものである。
そして、本発明の薬剤揮散具によれば、屋内はもちろん屋外のペット小屋などで、蚊や蚋、ハエ、ユスリカなどの各種害虫に対し、簡便でしかも長期間にわたり優れた害虫防除効果を示すので極めて実用性が高い。
The chemical volatilization device of the present invention thus obtained has a simple structure that does not require a driving device such as a motor or a spring, and uses the movement of air received from the outside, for example, air from an air conditioner, a fan, or wind entering through a window. Then, the insect repellent component is volatilized from the corrugated cardboard laminate type drug carrier. The drug carrier may be housed in a breathable cartridge so that a human finger or the like does not touch the drug carrier.
The amount of insecticide volatilization from the drug carrier is about 0.01 to 0.5 mg per hour, although it depends on the place of use and wind power, for example, a sufficient pest control effect in a normal 6 tatami living room. Play. Here, the pest control effect means an insect control effect in a broad sense including a biting prevention and repelling action against a mosquito without necessarily killing an insecticidal action leading to lethality.
The results of the present invention are based on the fact that the room temperature volatile insect repellent component used in the present invention has a very high basic insecticidal activity, although the vapor pressure is somewhat lower than that of conventional empentrin, the material and structure of the corrugated cardboard piece type, etc. It was obtained for the first time after considering various combinations with the.
And, according to the chemical volatilization device of the present invention, it exhibits an excellent pest control effect over a long period of time against various pests such as mosquitoes, moths, flies, chironomids in an indoor pet house as well as indoors. Very practical.

［殺虫効力試験］：１５ｍ3の部屋で風速０．５ｍ／秒の条件を設定し、アカイエカ成虫に対する殺虫効果を調べた。結果は、市販蚊取製剤と比較して、○、△、×で評価した。
According to Example 1 and Example 2, various chemical volatilization devices (A according to Example 1 and A according to Example 2) were prepared and used in a room similarly equipped with an air conditioner. . The following insecticidal efficacy test was conducted at the start of use and one month later, and the evaluation results are shown in Table 1.
[Insecticidal efficacy test]: The condition of wind speed of 0.5 m / sec was set in a room of 15 m 3, and the insecticidal effect on the mosquitoes was examined. The results were evaluated as ○, Δ, and × compared with the commercially available mosquito repellent preparation.
貫通穴の向きを交互に形成した本発明の薬剤揮散具は、平板からの自然蒸散方式(比較例４)や貫通穴の向きが同方向の段ボール片積層型（比較例３）に比べ、長期にわたり優れた害虫防除効果を示し極めて効率的な揮散性能を奏することが認められた。
これに対し、比較例１のように常温揮散性を有さないプラレトリンを用いた場合は本発明の薬剤揮散システムに合致せず、また、比較例２の如く、薬剤担持量が３０ｍｇより少ない場合は防除効果が長期間持続しなかった。
The chemical volatilization device of the present invention in which the orientations of the through holes are alternately formed is longer than the natural evaporation method from the flat plate (Comparative Example 4) or the corrugated cardboard laminated type in which the orientation of the through holes is the same direction (Comparative Example 3). It was confirmed that it exhibited an excellent pest control effect and exhibited extremely efficient volatilization performance.
On the other hand, when praretrin that does not have room temperature volatility is used as in Comparative Example 1, it does not match the chemical volatilization system of the present invention, and when the amount of drug loaded is less than 30 mg as in Comparative Example 2. The control effect did not last for a long time.
