Description

本発明は、蚊、ブユ等の飛翔害虫を駆除又は忌避するために、網戸に固定して、常温揮散性薬剤を効率的に揮散させる薬剤揮散体及びこれを用いた飛翔害虫防除方法に関するものである。 The present invention relates to a drug volatilizer that is attached to a screen door and efficiently volatilizes a drug that is volatile at room temperature in order to exterminate or repel flying pests such as mosquitoes and black flies, and a method for controlling flying pests using the same.

従来から常温揮散性薬剤を空気中に揮散させることによって、飛翔害虫の駆除や忌避を行う防除剤は知られており、例えば特許文献1に開示されている。また、使用期間中に薬剤を安定して揮散させるため、ポリエチレン等のポリオレフィン系樹脂に薬剤を練り込んだ担体を用いた薬剤揮散体が、例えば特許文献2に開示されている。
さらに、常温揮散性薬剤を含有する担体をコンパクトな薬剤容器の内部に収納し、通常の室温で吊り下げ又は置いて使用する薬剤揮散体が、特許文献3に開示されている。さらにまた、網戸に固定することにより飛翔害虫を駆除又は忌避する方法が特許文献4に開示されている。
Conventionally, pesticides that exterminate or repel flying pests by volatilizing a room temperature volatile agent into the air have been known, and are disclosed, for example, in Patent Document 1. In addition, in order to stably volatilize the agent during the period of use, a drug volatilizer that uses a carrier in which the drug is kneaded into a polyolefin resin such as polyethylene is disclosed, for example, in Patent Document 2.
Furthermore, a drug volatilizer in which a carrier containing a room temperature volatile drug is stored inside a compact drug container and used by hanging or placing it at normal room temperature is disclosed in Patent Document 3. Furthermore, a method for exterminating or repelling flying pests by fixing it to a screen door is disclosed in Patent Document 4.

ところで、前記の通常の室温で吊り下げ又は置いて使用する場合には、設置される揮散体の周辺は比較的オープンな空間であるのに対して、網戸に固定して使用する場合は、揮散体と網戸が接近した状態であり、空隙率の高い網戸であっても薬剤の揮散状態は通常の室温で吊り下げ又は置いて使用する場合と比べて、揮散体周辺の薬剤揮散環境が異なると思われた。その結果、飛翔害虫を駆除又は忌避効果をさらに上げるためには、揮散体と網戸の位置関係等、さらなる工夫が必要であった。 When used by hanging or placing at normal room temperature, the area around the installed volatilizer is a relatively open space, whereas when used by fixing to a screen door, the volatilizer and the screen door are in close proximity, and it was thought that the volatilization state of the pesticide would be different in the pesticide volatilization environment around the volatilizer compared to when it is hung or placed at normal room temperature, even if the screen door has a high porosity. As a result, further ingenuity was required, such as the relative positions of the volatilizer and the screen door, in order to further increase the effect of exterminating or repelling flying pests.

本発明は、常温揮散性薬剤を含有する担体を扁平状の薬剤容器の内部に収納し、網戸に固定して用いる薬剤揮散体であって、揮散した薬剤を含む気流を調整することにより、網戸周辺に飛来する蚊、ブユ等の飛翔害虫をより効率的に駆除又は忌避することが可能な薬剤揮散体及びこれを用いた飛翔害虫防除方法を提供する目的でなされたものである。 The present invention is a drug volatilizer in which a carrier containing a room temperature volatile drug is stored inside a flat drug container and fixed to a screen door, and the purpose of the invention is to provide a drug volatilizer that can more efficiently exterminate or repel flying pests such as mosquitoes and black flies that fly around the screen door by adjusting the airflow containing the volatilized drug, and a flying pest control method using the same.

本発明は、以下の構成が前記目的を達成するために優れた効果を奏することを見出したものである。すなわち、
[1]常温揮散性薬剤を含有する担体を薬剤容器の内部に収納した網戸に固定して用いる飛翔害虫防除のための薬剤揮散体において、前記薬剤容器の網戸と直接に対向する側の外表面の外周縁部に、少なくとも2つの厚み部材が設けられ、これらの厚み部材のうちの2つは、互いに対向する位置に設けられ、前記の互いに対向する位置に設けられたそれぞれの厚み部材の長さは、前記外周縁部の周の全長の5%以上40%以下であることを特徴とする飛翔害虫防除用薬剤揮散体。
The present invention has found that the following configurations are effective in achieving the above-mentioned object.
[1] A drug volatilizer for controlling flying pests, which is used by fixing a carrier containing a room temperature volatile drug to a screen door stored inside a drug container, characterized in that at least two thickness members are provided on the outer peripheral edge of the outer surface of the drug container on the side directly facing the screen door, two of these thickness members are provided in positions opposite each other, and the length of each of the thickness members provided in the positions opposite each other is 5% to 40% of the total circumference of the outer peripheral edge.

[2]前記の網戸と直接に対向する側の前記薬剤容器の外表面の形状が方形であり、前記の互いに対向する位置に設けられたそれぞれの厚み部材の長さは、前記外周縁部を構成する端縁部及び側縁部のいずれか一方の長さの26%以上であることを特徴とする[1]に記載の飛翔害虫防除用薬剤揮散体。
[3]前記厚み部材の厚みが0.5mm~5mmであることを特徴とする[1]又は[2]に記載の飛翔害虫防除用薬剤揮散体。
[4]前記厚み部材が、面ファスナーからなることを特徴とする[1]乃至[3]のいずれか1項に記載の飛翔害虫防除用薬剤揮散体。
[2] A flying pest control drug volatilizer as described in [1], characterized in that the shape of the outer surface of the drug container on the side directly facing the screen door is rectangular, and the length of each of the thickness members provided in the opposing positions is 26% or more of the length of either one of the end edge portions and side edge portions that constitute the outer circumferential edge portion.
[3] The flying insect pest control drug volatilizer according to [1] or [2], characterized in that the thickness of the thick member is 0.5 mm to 5 mm.
[4] A flying pest control drug volatilizer described in any one of [1] to [3], characterized in that the thick member is made of a hook-and-loop fastener.

本発明の飛翔害虫防除用薬剤揮散体は、網戸と直接に対向する側に厚み部材が設けられるので、本発明の飛翔害虫防除用薬剤揮散体と網戸との間に空間部が生じ、本発明の飛翔害虫防除用薬剤揮散体から揮散した常温揮散性薬剤がこの空間部に漂う。そして、少なくとも2つの所定長さの厚み部材が、薬剤容器の網戸と直接に対向する側の外表面の外周縁部に、互いに対向する位置に配されるので、前記の空間部に漂う常温揮散性薬剤は、厚み部材に沿った方向、すなわち、この空間部から厚み部材が配されない2つの外周縁部に向かう方向に2つの気流が生じる。この2つの方向は、反対方向、すなわち、生じる気流の方向がほぼ180°異なる方向となるので、2つの気流が重なって干渉し、気流がその流れの方向以外の方向に拡散したり、気流の速度が低下したりするのを抑制できる。このため、本発明においては、本発明の飛翔害虫防除用薬剤揮散体から網戸側に揮散した常温揮散性薬剤が網戸に沿ってその濃度が保たれたまま、互いに反対の2つの方向に生じる気流にのって流れることができる。このため、有効な濃度を保持した状態で、常温揮散性薬剤が網戸表面に流れることとなり、この飛翔害虫防除用薬剤揮散体を設置した網戸の周辺に対して、常温揮散性薬剤の効果を発揮することができる。すなわち、この飛翔害虫防除用薬剤揮散体を設置した網戸の周辺に飛来する蚊、ブユ等の飛翔害虫を効率的に駆除又は忌避でき、その実用性は極めて高い。 The flying pest control agent volatilizer of the present invention has a thickness member on the side directly facing the screen door, so that a space is created between the flying pest control agent volatilizer of the present invention and the screen door, and the room temperature volatile agent volatilized from the flying pest control agent volatilizer of the present invention floats in this space. At least two thickness members of a predetermined length are arranged in positions facing each other on the outer peripheral edge of the outer surface of the drug container on the side directly facing the screen door, so that the room temperature volatile agent floating in the space generates two airflows in a direction along the thickness member, that is, in a direction from this space toward the two outer peripheral edges where the thickness member is not arranged. These two directions are opposite directions, that is, the directions of the generated airflows are almost 180° different, so that the two airflows overlap and interfere with each other, and it is possible to prevent the airflow from diffusing in a direction other than the flow direction or the airflow speed from decreasing. Therefore, in the present invention, the room temperature volatile agent that volatilizes toward the screen door from the flying pest control agent volatilizer of the present invention can flow along the screen door with the air currents that occur in two opposite directions while maintaining its concentration. Therefore, the room temperature volatile agent flows to the surface of the screen door while maintaining an effective concentration, and the effect of the room temperature volatile agent can be exerted around the screen door on which the flying pest control agent volatilizer is installed. In other words, flying pests such as mosquitoes and black flies that fly into the area around the screen door on which the flying pest control agent volatilizer is installed can be efficiently exterminated or repelled, and its practicality is extremely high.

この発明は、図1に示すように、常温揮散性薬剤を含有する担体を薬剤容器11の内部に収納した網戸に固定して用いる飛翔害虫防除用薬剤揮散体(以下、単に「薬剤揮散体」と称することがある。)10に係る発明である。 As shown in FIG. 1, this invention relates to a chemical volatilizer for controlling flying pests (hereinafter sometimes simply referred to as "chemical volatilizer") 10, which is used by fixing a carrier containing a room temperature volatile chemical to a screen door housed inside a chemical container 11.

(常温揮散性薬剤)
前記常温揮散性薬剤とは、常温(25℃)で揮散性を有する薬剤をいい、空気中に揮散するものであれば特に限定されない。前記常温揮散性薬剤の例としては、より強力な効果を発揮できる点でピレスロイド系薬剤を用いるのが好ましく、揮散性能や飛翔害虫に対する基礎活性が高いメトフルトリン、プロフルトリン、エンペントリン及びトランスフルトリンの1種又は2種以上が好適である。
(Room temperature volatile agent)
The room temperature volatile agent refers to an agent that is volatile at room temperature (25° C.), and is not particularly limited as long as it volatilizes into the air. As an example of the room temperature volatile agent, it is preferable to use a pyrethroid agent in that it can exert a stronger effect, and one or more of metofluthrin, profluthrin, empenthrin, and transfluthrin, which have high volatility performance and basic activity against flying pests, are suitable.

In addition to the above-mentioned agents, stabilizers such as fragrances, colorants, antistatic agents, and antioxidants, and ultraviolet absorption inhibitors may be appropriately added.

(担体)
前記担体は、前記常温揮散性薬剤を含浸や練り込み等により、保持させるためのものをいう。
前記担体を構成する材質としては、紙、繊維、樹脂等のいずれも使用可能であり、その中でも、前記常温揮散性薬剤を練り込んだ樹脂製の担体(以下、樹脂製の担体を「樹脂担体」、常温揮散性薬剤を練り込んだ樹脂担体を「常温揮散性薬剤含有樹脂担体」と称することがある。)を採用すると、使用期間中の薬剤の徐放性を制御でき、安定した薬剤揮散量を実現できること、かつ、雨など水分による薬剤の流れ落ちの心配がない点から好ましい。
この樹脂の材質としては、ポリエチレン、ポリプロピレン、ポリビニルアルコール、ポリ酢酸ビニル、ポリブタジエン、ポリイソプレン、エチレンーメチルメタクリレート共重合体、スチレンーブタジエン共重合体等のポリオレフィン系樹脂が好ましい。
(Carrier)
The carrier is intended to hold the room temperature volatile drug by impregnation, kneading, or the like.
The material constituting the carrier can be any of paper, fiber, resin, etc., and among these, a resin carrier into which the room temperature volatile drug has been kneaded (hereinafter, a resin carrier may be referred to as a "resin carrier" and a resin carrier into which a room temperature volatile drug has been kneaded may be referred to as a "resin carrier containing a room temperature volatile drug") is preferred because it makes it possible to control the sustained release of the drug during the period of use, achieves a stable amount of drug volatilization, and eliminates the need to worry about the drug being washed away by moisture such as rain.
As the resin material, polyolefin resins such as polyethylene, polypropylene, polyvinyl alcohol, polyvinyl acetate, polybutadiene, polyisoprene, ethylene-methyl methacrylate copolymer, and styrene-butadiene copolymer are preferable.

前記樹脂担体の形状は、薬剤の揮散効率を考慮し網状形状が好ましい。網の線径としては、同じく揮散効率の点から0.1~2mmの範囲が好適であるが、薬剤の種類や使用期間に応じて、前記範囲内から適宜設定すればよい。すなわち、蒸気圧の高い薬剤の場合には、線径を大きくすることにより揮散を抑制するように調整し、蒸気圧の低い薬剤の場合は、線径を小さくすることによって揮散を促すように調整する。 The shape of the resin carrier is preferably a mesh shape, taking into consideration the efficiency of volatilization of the drug. The wire diameter of the mesh is preferably in the range of 0.1 to 2 mm, also from the viewpoint of volatilization efficiency, but may be appropriately set within the above range depending on the type of drug and the period of use. That is, in the case of a drug with a high vapor pressure, the wire diameter is adjusted to be large to suppress volatilization, and in the case of a drug with a low vapor pressure, the wire diameter is adjusted to be small to promote volatilization.

前記の網状形状の樹脂担体は、平面状であっても、多層構造となるように立体成形したものであってもよい。平面状の担体は、これを複数枚重ねて、立体状にして使用することができる。前記樹脂担体を複数枚重ねたり、立体成形することにより、薬剤揮散面積が増え、その分、常温揮散性薬剤の単位時間当たりの揮散量を増やすことが可能となる。さらに、複数枚の担体毎に薬剤の種類や濃度、網の線径を変え、各薬剤の特長を生かした製剤とすることもできる。
また、立体状の担体としては、前記した平面状の担体を複数枚重ねて立体状にしたものや、図2(b)に示すような、射出成形により、立体状に成形した立体状樹脂担体13’等があげられる。
The resin carrier of the net shape may be planar or may be three-dimensionally molded to have a multi-layer structure. Planar carriers can be used in a three-dimensional form by stacking a plurality of sheets of the carrier. By stacking a plurality of sheets of the resin carrier or forming them into a three-dimensional form, the drug volatilization area increases, and the amount of the drug volatilized at room temperature per unit time can be increased accordingly. Furthermore, the type and concentration of the drug and the wire diameter of the net can be changed for each of the plurality of carriers to make a formulation that takes advantage of the characteristics of each drug.
Examples of three-dimensional carriers include those formed by stacking multiple flat carriers as described above into a three-dimensional shape, and three-dimensional resin carriers 13' molded into a three-dimensional shape by injection molding, as shown in Figure 2 (b).

前記樹脂担体に保持される常温揮散性薬剤の配合量は、使用する薬剤の種類により異なるが、効果を発揮する有効成分量の確保、樹脂に薬剤を練り込んだ後の成形性、更に、担体表面に薬剤がブリードしてべたつきを起こすことを防止する点から2~12重量%の範囲とすることが好ましく、3~10重量%の範囲とすることがより好ましい。常温揮散性薬剤の配合量が2重量%未満の場合には、効果を発揮する有効成分量を確保することが困難となる場合がある。一方、12重量%を超えると、網目状の成形が困難となり、更に、網表面に薬剤が多量にブリードしてべたつきを起こしやすくなる傾向がある。 The amount of room temperature volatile drug held in the resin carrier varies depending on the type of drug used, but is preferably in the range of 2 to 12% by weight, more preferably 3 to 10% by weight, from the viewpoints of ensuring an effective amount of active ingredient, moldability after the drug is kneaded into the resin, and preventing the drug from bleeding onto the carrier surface and causing stickiness. If the amount of room temperature volatile drug is less than 2% by weight, it may be difficult to ensure an effective amount of active ingredient. On the other hand, if it exceeds 12% by weight, it becomes difficult to form a mesh shape, and there is a tendency for a large amount of drug to bleed onto the mesh surface, causing stickiness.

(薬剤容器)
本発明の薬剤揮散体は網戸に固定して、蚊、ブユ等の飛翔害虫を駆除又は忌避する。この薬剤揮散体を網戸に固定する場合、窓や雨戸を開閉する際に邪魔にならないよう前記薬剤容器は扁平形状にすることが好ましい。薬剤揮散体は容器内に収納された担体の表面を空気が流れることにより担体に含有された薬剤が徐々に揮散し、揮散した薬剤は薬剤容器に設けられた開口部より薬剤容器外へ放出される。
(Medicine container)
The agent volatilizer of the present invention is fixed to a screen door to exterminate or repel flying pests such as mosquitoes and black flies. When this agent volatilizer is fixed to a screen door, it is preferable that the agent container is flat so as not to get in the way when opening and closing a window or a storm shutter. The agent volatilizer is gradually vaporized by air flowing over the surface of the carrier stored in the container, and the vaporized agent is released outside the agent container from an opening provided in the agent container.

この薬剤容器として、扁平状の容器を用いる場合、網戸と対向する面の形状としては、正方形や長方形(図1(a))等の方形状、円(図4(a))等の略円状や楕円(図4(b))等の略楕円状等の形状を挙げることができるがこれらに限定されず、嗜好性に合わせた形状にすることができる。 When a flat container is used as the drug container, the shape of the surface facing the screen door can be a rectangular shape such as a square or rectangle (Fig. 1(a)), a roughly circular shape such as a circle (Fig. 4(a)), or a roughly elliptical shape such as an ellipse (Fig. 4(b)), but is not limited to these, and the shape can be made to suit preference.

また、前記薬剤容器の厚みは、3mm~10mmが好ましい。この範囲内とすることにより、網戸に固定しても、窓や雨戸と接触しないので、邪魔にならず、かつ、前記担体と容器内面との隙間を1mm以上とすることができ、前記常温揮散性薬剤の揮散をより効率よく行うことができる。 The thickness of the drug container is preferably 3 mm to 10 mm. By keeping the thickness within this range, even if it is fixed to a screen door, it does not come into contact with a window or a storm shutter, so it does not get in the way, and the gap between the carrier and the inner surface of the container can be made 1 mm or more, allowing the room temperature volatile drug to volatilize more efficiently.

前記の薬剤容器11の表面及び裏面には、図1(a)(b)に示すように、前記常温揮散性薬剤含有樹脂担体13から常温揮散性薬剤が放散される開口部12が形成される。当該開口部12の開口面積は、揮散を妨げない程度のものであれば良いが、前記薬剤容器の外表面のうち、網戸がある側と反対側(屋外側)の開口面積(A)と網戸がある側(屋内側)の開口面積(B)の比率A/Bが、2/1~1/2であることが好ましい。通常、空気の流れは、一般的に、容器の屋外側の開口部から流入したのち、容器内を通過し、屋内側の開口部から容器外に流出すると考えられるので、この範囲を外れると、屋外側から屋内側への空気の流れがうまく生じないおそれがあり、常温揮散性薬剤の揮散効率が低下する傾向が生じるおそれがある。 As shown in Fig. 1 (a) and (b), the front and back surfaces of the drug container 11 are provided with openings 12 through which the drug volatile at room temperature is diffused from the drug-containing resin carrier 13 volatile at room temperature. The opening area of the opening 12 may be any size that does not prevent the volatilization, but it is preferable that the ratio A/B of the opening area (A) on the side opposite the screen door (outdoor side) to the opening area (B) on the side with the screen door (indoor side) of the outer surface of the drug container is 2/1 to 1/2. Normally, air flows into the container from the opening on the outdoor side, passes through the container, and flows out of the container from the opening on the indoor side. If the ratio is outside this range, the air may not flow well from the outdoor side to the indoor side, and the efficiency of the drug volatile at room temperature may tend to decrease.

前記薬剤容器11の構造としては、例えば図2(a)に示すような、中央部平面シート状の浅底型容器状の樹脂部材を折り曲げたものが挙げられる。この場合、容器は前記折り曲げた部材の2つを一組として用い、それぞれの部材の折り曲げ面が重なりあうように組み立てられる。また、樹脂の一体成形品を使用することもできる。ここでいう樹脂の一体成形品とは、通常の射出成形又は真空成形で成形したもの等であれば成形方法は問わないが、屋外側と屋内側とをヒンジを用いて一体としたり、嵌合したりすることによって一体とすれば、製造工程をより簡略化することができる。 The structure of the drug container 11 can be, for example, as shown in FIG. 2(a), a folded resin member in the shape of a shallow container with a flat sheet in the center. In this case, the container is assembled by using two of the folded members as a set, with the folded surfaces of each member overlapping. It is also possible to use an integrally molded resin product. The integrally molded resin product referred to here can be any molding method, as long as it is molded by normal injection molding or vacuum molding, but the manufacturing process can be further simplified if the outdoor side and indoor side are integrated using a hinge or by fitting them together.

前記薬剤容器に用いる樹脂の材質としては、ポリエチレンテレフタレート(PET)、ポリブチレンテレフタレート(PBT)等のポリエステル樹脂、ポリエチレン、ポリプロピレン等のポリオレフィン樹脂、ナイロン、ポリアミド等、種々の樹脂材料が使用可能であるが、強度やその性質を考慮すると、ポリエチレンテレフタレート(PET)やポリブチレンテレフタレート(PBT)を用いるのが好ましい。 Various resin materials can be used for the drug container, including polyester resins such as polyethylene terephthalate (PET) and polybutylene terephthalate (PBT), polyolefin resins such as polyethylene and polypropylene, nylon, polyamide, etc., but considering the strength and properties, it is preferable to use polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).

また、これら樹脂の厚みは種々のものが使用可能であるが、樹脂担体の形状やその揮散性能との関係、経済性等の点から、0.05mm~2mmのものを使用するのが好ましい。 Although various thicknesses of resins can be used, it is preferable to use resins with a thickness of 0.05 mm to 2 mm in terms of the shape of the resin carrier, its volatilization performance, and economics.

(厚み部材)
前記薬剤容器は、その外表面であって、網戸と直接に対向する側の外表面に、厚み部材が設けられる。この厚み部材を設けることにより、本発明にかかる薬剤揮散体を網戸に取り付けることができると共に、薬剤容器と網戸との間に一定の隙間を持たせることができるので、その隙間に気流を通しやすくすることができ、担体から揮散する常温揮散性薬剤を効率よく拡散することができると思われる。
(Thickness member)
The chemical container is provided with a thickness member on its outer surface, which is the outer surface directly facing the screen door. By providing this thickness member, the chemical volatilizer of the present invention can be attached to the screen door, and a certain gap can be provided between the chemical container and the screen door, which makes it easier for air to pass through the gap, and it is believed that the room temperature volatile chemical volatilized from the carrier can be efficiently diffused.

前記の通り、前記薬剤容器の、網戸と直接に対向する側の外表面の所定の位置に、複数個の前記厚み部材が設けられる。具体的には、網戸と直接に対向する側の前記薬剤容器の外表面の外周縁部(以下、単に「外周縁部」と称することがある。)に、少なくとも2つの前記厚み部材が設けられ、これらの厚み部材のうちの2つは、互いに対向する位置に設けられる。 As described above, a plurality of the thickness members are provided at predetermined positions on the outer surface of the drug container on the side directly facing the screen door. Specifically, at least two of the thickness members are provided on the outer peripheral edge portion (hereinafter sometimes simply referred to as the "outer peripheral edge portion") of the outer surface of the drug container on the side directly facing the screen door, and two of these thickness members are provided at positions opposite each other.

この位置に設けることにより、前記飛翔害虫防除用薬剤揮散体と網戸との間に生じる空間部に漂う常温揮散性薬剤は、図3(a)の矢印で示すように、厚み部材14に沿った方向、すなわち、この空間部から厚み部材14が配されない2箇所の外周縁部に向かう方向に2つの気流が生じる。この2つの方向は、反対方向、すなわち、生じる気流の方向がほぼ180°異なる方向であるので、2つの気流が重なることはない。このため、2つの気流の干渉による、気流の流れ方向以外への拡散や気流の速度低下を抑制でき、前記飛翔害虫防除用薬剤揮散体から網戸側に揮散し、漂っていた常温揮散性薬剤が網戸に沿って、その濃度が保たれた状態で、互いに反対の2つの方向に生じる気流にのって流れることができる。このため、有効な濃度を保持した状態で、常温揮散性薬剤が網戸表面に流れることとなり、この飛翔害虫防除用薬剤揮散体を設置した網戸の周辺に対して、常温揮散性薬剤の効果を発揮することができる。 By placing it in this position, the room temperature volatile agent floating in the space between the flying pest control agent volatilizer and the screen door generates two air currents in the direction along the thickness member 14, that is, in the direction from this space toward the two outer periphery parts where the thickness member 14 is not disposed, as shown by the arrows in Figure 3 (a). These two directions are opposite, that is, the directions of the generated air currents are almost 180° different, so the two air currents do not overlap. Therefore, it is possible to suppress the diffusion in the direction other than the flow direction of the air current and the decrease in the speed of the air current due to the interference between the two air currents, and the room temperature volatile agent that has volatilized from the flying pest control agent volatilizer toward the screen door and has been floating can flow along the screen door on the air currents generated in two opposite directions while maintaining its concentration. As a result, the room temperature volatile chemical flows onto the surface of the screen while maintaining an effective concentration, and the effect of the room temperature volatile chemical can be exerted around the screen on which the flying insect control chemical volatile body is installed.

一方、厚み部材14が1つの場合、常温揮散性薬剤は、図3(b)の矢印で示すように、厚み部材14が設けられる部分以外の3方向へ拡散していくため、特定の方向に向かう気流が生じにくく、本願の発明の効果を生じ難くなる傾向が生じる。
また、厚み部材14の2つが互いに対向する位置に設けられていない場合、常温揮散性薬剤は、図3(c)の矢印で示すように、厚み部材14に沿って、厚み部材14が設けられる部分以外の方向へ気流が生じるが、その気流の方向は、直角又はそれに近いため、2つの気流で干渉が生じる。このため、2つの気流の間の方向にも流れが生じ、結果的に、気流の拡散が生じてしまい、十分な濃度を保持することが困難になるおそれがある。また、これにより、気流の速度が低下するおそれがあり、より遠くまで常温揮散性薬剤が到達しにくくなるおそれが生じる。
On the other hand, when there is only one thick member 14, the room temperature volatile drug diffuses in three directions other than the part where the thick member 14 is provided, as shown by the arrows in Figure 3 (b), making it difficult for an airflow to flow in a specific direction to occur, and there is a tendency for the effect of the present invention to be difficult to achieve.
In addition, when the two thickness members 14 are not provided at positions facing each other, the room temperature volatile medicine generates an airflow along the thickness member 14 in a direction other than the part where the thickness member 14 is provided, as shown by the arrow in Fig. 3 (c), but the direction of the airflow is perpendicular or close to it, so interference occurs between the two airflows. Therefore, a flow also occurs in the direction between the two airflows, and as a result, the airflow is diffused, which may make it difficult to maintain a sufficient concentration. In addition, this may cause the speed of the airflow to decrease, making it difficult for the room temperature volatile medicine to reach a greater distance.

この厚み部材の形状は、設置する外周縁部の形状に合わせたものでもよく、異なってもよい。前記厚み部材の形状が設置する外周縁部の形状と異なる場合は、厚み部材の一部がこの外周縁部に取り付けられればよい。 The shape of this thickness member may match the shape of the outer peripheral edge portion to which it is to be installed, or it may be different. If the shape of the thickness member is different from the shape of the outer peripheral edge portion to which it is to be installed, it is sufficient that a part of the thickness member is attached to this outer peripheral edge portion.

例えば、網戸と直接に対向する側の前記薬剤容器の外表面の形状が正方形や長方形、平行四辺形等の方形状の場合、その外周縁部は直線部分を含むので、厚み部材の形状は、正方形、長方形等の方形状とすると、厚み部材の全面を前記外周縁部に取り付けることができる。 For example, if the shape of the outer surface of the drug container directly facing the screen door is a rectangular shape such as a square, rectangle, or parallelogram, the outer periphery includes straight lines, so if the shape of the thickness member is a rectangular shape such as a square or rectangle, the entire surface of the thickness member can be attached to the outer periphery.

また、網戸と直接に対向する側の前記薬剤容器の外表面の形状が円形や楕円形等、曲線部分を有する場合、厚み部材の形状としては、前記外周縁部の該当位置の形状に沿わせた形状、すなわち、弧状等の曲線状であってもよく、また、正方形、長方形等の方形状としてもよい。厚み部材の形状を方形状とする場合、その両端部を前記外周縁部に接しさせ、この部分で取り付ければよい。 In addition, if the shape of the outer surface of the drug container directly facing the screen door has a curved portion, such as a circle or ellipse, the shape of the thickness member may be a shape that follows the shape of the corresponding portion of the outer periphery, i.e., a curved shape such as an arc, or a rectangular shape such as a square. If the shape of the thickness member is rectangular, both ends of the thickness member may be in contact with the outer periphery and attached at this portion.

前記厚み部材として、方形のものを用いる場合は、対向する2つの厚み部材は、平行になるように配するのがよい。
前記飛翔害虫防除用薬剤揮散体と網戸との間に生じる空間部に漂う常温揮散性薬剤は、厚み部材に沿った方向、すなわち、この空間部から厚み部材が配されない2箇所の外周縁部に向かう方向に2つの気流が生じるが、2つの厚み部材を平行になるように設けると、この2つの気流の方向の差を、180°により近づけることができ、この発明の効果をより確実に発揮することができる。
When a rectangular member is used as the thickness member, it is preferable that two opposing thickness members are arranged in parallel.
The room temperature volatile chemical agent floating in the space created between the flying pest control chemical volatilizer and the screen creates two air currents in a direction along the thickness member, i.e., in a direction from this space toward the two outer peripheral edge portions where no thickness member is located. However, if the two thickness members are arranged parallel to each other, the difference in direction between these two air currents can be made closer to 180°, and the effects of the invention can be more reliably achieved.

前記の互いに対向する位置に設けられたそれぞれの厚み部材の長さは、前記外周縁部の周の全長の5%以上がよく、10%以上がより好ましい。5%より短いと、厚み部材に沿って気流が移動する距離が短く、また、厚み部材が配されない2箇所の外周縁部が長くなるため、前記飛翔害虫防除用薬剤揮散体と網戸との間に生じる空間部に漂う常温揮散性薬剤が流れ出るそれぞれ気流の方向を一方向に維持することが難しくなり、ある程度の角度で広がってしまうおそれがある。その結果、この発明の効果を得られ難くなるおそれが生じる。
一方、それぞれの厚み部材の長さは、前記外周縁部の周の全長の40%以下がよく、30%以下がより好ましい。40%より長いと、厚み部材が配されない2箇所の外周縁部が狭くなりすぎ、前記飛翔害虫防除用薬剤揮散体と網戸との間に生じる空間部に漂う常温揮散性薬剤を効率よく外部に送り出すことが難しくなる傾向が生じる。
The length of each of the thickness members provided at the mutually opposing positions is preferably 5% or more of the total circumference of the outer peripheral edge, and more preferably 10% or more. If it is shorter than 5%, the distance that the airflow moves along the thickness member is short, and the two outer peripheral edges where the thickness members are not arranged are long, so it becomes difficult to maintain the direction of each airflow from which the room temperature volatile drug floating in the space between the flying pest control drug volatilizer and the screen door flows in one direction, and there is a risk that it will spread at a certain angle. As a result, there is a risk that it will be difficult to obtain the effect of this invention.
On the other hand, the length of each thickness member is preferably 40% or less of the total circumference of the outer peripheral edge, more preferably 30% or less. If it is longer than 40%, the two outer peripheral edges where the thickness members are not disposed will be too narrow, and it will tend to be difficult to efficiently send the room temperature volatile drug floating in the space between the flying insect pest control drug volatilizer and the screen door to the outside.

また、前記の網戸と直接に対向する側の前記薬剤容器の外表面の形状が方形である場合、前記外周縁部も方形となり、直線状の端縁部や側縁部を有することとなる。そして、厚み部材も方形のものを用いることができる。このとき、前記厚み部材が、前記外周縁部の端縁部又は側縁部に設けられる場合、前記厚み部材の長さは、前記の条件を満たすと共に、当該厚み部材が設置される前記薬剤容器の端縁部の長さ又は前記側縁部の長さに対して26~100%の長さを有することが好ましく、30~90%の長さを有することがより好ましい。26%よりも短いと、厚み部材に沿って気流が移動する距離が短く、また、厚み部材が配された端縁部又は側縁部において、厚み部材が配されない部分が長くなり、この部分からも常温揮散性薬剤が流れ出るおそれが生じる。このため、前記飛翔害虫防除用薬剤揮散体と網戸との間に生じる空間部に漂う常温揮散性薬剤が流れ出るそれぞれ気流の方向を一方向にすることが難しくなり、広がる傾向が生じ、その結果、この発明の効果を得られ難くなるおそれが生じる。 In addition, if the shape of the outer surface of the drug container directly facing the screen door is rectangular, the outer peripheral edge will also be rectangular and will have linear edges and side edges. A rectangular thickness member can also be used. In this case, if the thickness member is provided on the edge or side edge of the outer peripheral edge, the length of the thickness member satisfies the above conditions and is preferably 26 to 100% of the length of the edge or side edge of the drug container on which the thickness member is installed, and is more preferably 30 to 90%. If it is shorter than 26%, the distance that the airflow travels along the thickness member will be short, and the portion of the edge or side edge where the thickness member is provided where the thickness member is not provided will be long, and there is a risk that the room temperature volatile drug will flow out from this portion. This makes it difficult to direct the air currents from which the room temperature volatile chemicals floating in the space between the flying insect control chemical volatilizer and the screen door flow in one direction, and they tend to spread, which can make it difficult to obtain the benefits of this invention.

前記厚み部材の幅は薬剤容器の大きさにもよるが揮散性薬剤の拡散効果を妨げない程度であればよく、3~20mmが好ましい。 The width of the thickness member depends on the size of the drug container, but should be sufficient as long as it does not interfere with the diffusion effect of the volatile drug, and is preferably 3 to 20 mm.

前記厚み部材としては、その効果を果たせる限り、問わないが、硬質や軟質、発泡質の樹脂フィルムや樹脂板等の樹脂体、天然や合成の繊維質体、樹脂製のモノフィラメントあるいはマルチフィラメント、パルプ質体やそれらを組み合わせたもののシート状物や板状物が用いられる。具体的には、樹脂等のフィルム、樹脂等の板、テープ、両面テープ、面ファスナー等を用いることができる。前記テープや両面テープの接着層には、粘着剤や接着剤が用いられる。また、前記面ファスナーのファスナー部は、樹脂製のモノフィラメントあるいはマルチフィラメント、パルプ質体やそれらを組み合わせたものが用いられる。 The thickness member can be any material as long as it can achieve its effect, including resin bodies such as hard, soft, or foamed resin films or resin plates, natural or synthetic fibrous bodies, resin monofilaments or multifilaments, pulp bodies, or sheet-like or plate-like materials made from a combination of these. Specifically, resin films, resin plates, tapes, double-sided tapes, hook-and-loop fasteners, etc. can be used. The adhesive layer of the tapes or double-sided tapes uses a pressure-sensitive adhesive or adhesive. The fastener portion of the hook-and-loop fastener can be made from resin monofilaments or multifilaments, pulp bodies, or a combination of these.

前記厚み部材は、この厚み部材が有する、又はこの厚み部材に塗工した粘着剤や接着剤により前記薬剤容器に固定される。そして、薬剤容器と網戸との固定は、この厚み部材が有する粘着剤、接着剤、面ファスナーのファスナー部等によって固定される。 The thickness member is fixed to the drug container by an adhesive or glue contained in the thickness member or coated on the thickness member. The drug container and the screen door are fixed together by an adhesive or glue contained in the thickness member, a fastener portion of a hook-and-loop fastener, or the like.

前記厚み部材として面ファスナーを用いる場合、この面ファスナーは、樹脂製のモノフィラメントあるいはマルチフィラメントである面ファスナーのフック面あるいはループ面のいずれかを使用し、容器と網戸間の固定機能を発揮することができ、厚み部材としてより好ましい。 When a hook-and-loop fastener is used as the thickness member, the hook-and-loop fastener is made of a resin monofilament or multifilament, and either the hook surface or the loop surface can be used to secure the container and the screen door, making it more preferable as the thickness member.

前記厚み部材を設置した場合、厚み部材の厚みは、実質、網戸と薬剤容器外表面との離間距離に相当する。
例えば、図2(c)に示すように、厚み部材14として面ファスナー14’を用いる場合、網戸15に取り付けると、網戸15と薬剤容器11との間に隙間が生じる。これの隙間は、薬剤容器に取り付けられる面ファスナー本体の厚みに相当する。
When the thickening member is provided, the thickness of the thickening member substantially corresponds to the distance between the screen door and the outer surface of the medicine container.
For example, as shown in Fig. 2(c), when a hook-and-loop fastener 14' is used as the thickness member 14, when it is attached to a screen door 15, a gap is generated between the screen door 15 and the drug container 11. This gap corresponds to the thickness of the hook-and-loop fastener body attached to the drug container.

厚み部材の厚みは本発明の効果を果たせる限り問わないが、厚みを0.5mm~5mmとすれば、網戸に固定使用時、雨戸の開閉の邪魔にならず、また、この厚みにより生じる隙間に気流を通しやすくすることができ、担体から揮散する常温揮散性薬剤を効率よく拡散することができる。 The thickness of the material is not important as long as it can achieve the effects of the present invention, but if the thickness is between 0.5 mm and 5 mm, when it is attached to a screen door, it will not interfere with opening and closing the shutter. In addition, this thickness allows air to easily pass through the gaps created, allowing the room temperature volatile chemicals that volatilize from the carrier to be diffused efficiently.

本発明により、容器と網戸との間に位置する厚み部材により一定の隙間を持たせることにより、前記飛翔害虫防除用薬剤揮散体と網戸との間に空間部が生じ、ここに常温揮散性薬剤を漂わせることができる。そして、厚み部材の厚みが所定範囲なので、その空間部に漂う揮散性薬剤の気流の方向を、厚み部材に沿った方向の2方向のいずれかに揃わせることがより容易となる。このため、担体からの揮散性薬剤が集約されて効率よく気流を生じさせることができ、この発明の効果が発揮される。 According to the present invention, by providing a certain gap by using a thickness member positioned between the container and the screen, a space is created between the flying pest control agent volatilizer and the screen, and the room temperature volatile agent can be allowed to drift in this space. And because the thickness of the thickness member is within a specified range, it is easier to align the airflow direction of the volatile agent drifting in the space in one of two directions along the thickness member. As a result, the volatile agent from the carrier is concentrated, and an airflow can be generated efficiently, thereby achieving the effects of this invention.
