Description

この発明は、防虫性を備える合成樹脂製の管に関するものである。   The present invention relates to a tube made of a synthetic resin having insect repellent properties.

従来、合成樹脂製の管として、例えばエアコンのドレンホースに、虫の侵入を防ぐために、キャップとかバルブを取り付けることがあった(例えば、特許文献1、2参照)。つまり、このキャップやバルブは、ドレンホースの排出側の先端に取り付けられて、ドレン水の排出を許容しながら、虫の侵入を防止するものであった。   Conventionally, as a synthetic resin pipe, for example, a cap or a valve is sometimes attached to a drain hose of an air conditioner in order to prevent insects from entering (see, for example, Patent Documents 1 and 2). In other words, the cap and the valve are attached to the drain hose discharge end, and prevent the insect from entering while allowing the drain water to be discharged.

以下、この発明に係る合成樹脂製の管を実施するための形態を図面に基づいて説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for implementing a synthetic resin pipe according to the present invention will be described with reference to the drawings.

図1は、本発明の第一の実施の形態を示す。図中符号1は、防虫性を備える合成樹脂製の管を示す。   FIG. 1 shows a first embodiment of the present invention. Reference numeral 1 in the figure indicates a tube made of a synthetic resin having insect repellent properties.

この管1は、例えば、配線・配管材(配線材または配管材)を収容保護する管であって、地中に埋設されたり、コンクリート構造物内に埋設されたり、あるいは露出して配設されたりする。ここで、管1は、防虫成分を含有する防虫層2が、管1の内面側に露出するようにして管1の長手方向に断続的に形成される。   The pipe 1 is, for example, a pipe that accommodates and protects wiring / piping material (wiring material or piping material), and is buried in the ground, buried in a concrete structure, or exposed. Or Here, the tube 1 is intermittently formed in the longitudinal direction of the tube 1 so that the insect-repellent layer 2 containing the insect-repellent component is exposed on the inner surface side of the tube 1.

詳細には、管1は、防虫成分を含有することなく管1の長手方向に連続して形成される非防虫層3を備え、その非防虫層3の内面に、前記防虫層2が設けられる。   Specifically, the tube 1 includes a non-insect repellent layer 3 formed continuously in the longitudinal direction of the tube 1 without containing an insect repellent component, and the insect repellent layer 2 is provided on the inner surface of the non-insect repellent layer 3. .

具体的には、管1は、可撓性を備える波付管からなる。そして、管1は、基本的には、全長が非防虫層3からなるが、部分的に、防虫層2が加わった二層構造を有する。   Specifically, the tube 1 is a corrugated tube having flexibility. The tube 1 basically has a two-layer structure in which the entire length is composed of the non-insect repellent layer 3 but the insect repellent layer 2 is partially added.

非防虫層3は、例えば、塩化ビニル樹脂とかポリエチレン樹脂とかナイロン樹脂等の合成樹脂材料によって形成される。   The non-insect repellent layer 3 is formed of, for example, a synthetic resin material such as vinyl chloride resin, polyethylene resin, or nylon resin.

防虫層2は、非防虫層3の内面に、防虫成分を含有する防虫剤が塗布されてその防虫剤が硬化して被膜化されて形成される。この防虫剤は、例えば合成樹脂等に防虫成分を混合したもの、詳細には、バインダー樹脂と揮発性溶剤と防虫成分とを含むものであって、塗布後に、揮発性溶剤が揮発することで、防虫剤は、硬化して被膜化される。より詳細には、非防虫層3を、ブロー成形によって形成し、そのブロー成形時に、防虫剤を内部に噴出することにより、その防虫剤を非防虫層3の内面に塗布して、防虫層2を形成する。   The insect repellent layer 2 is formed by applying an insect repellent containing an insect repellent component on the inner surface of the non-insect repellent layer 3 and curing the insect repellent to form a film. This insect repellent is, for example, a mixture of an insect repellent component in a synthetic resin or the like, specifically, a binder resin, a volatile solvent, and an insect repellent component, and after application, the volatile solvent volatilizes, The insect repellent is cured to form a film. More specifically, the non-insect repellent layer 3 is formed by blow molding, and the insect repellent is applied to the inner surface of the non-insect repellent layer 3 by spraying the repellent to the inside at the time of the blow molding. Form.

ここで、防虫成分は、例えばゴキブリとかムカデとかその他の虫を防ぐための防虫成分であって、例えば、ゴキブリに対する防虫効果が高いピレスロイド系化合物であったり、有機リン剤、カーバメート剤、ホウ素化合物、フッ素化合物であったり、白蟻の食害を防ぐためのクロチアニジン等のネオニコチノイド系化合物であったりする。   Here, the insect repellent component is an insect repellent component for preventing cockroaches, centipedes or other insects, for example, a pyrethroid compound having a high insect repellent effect against cockroaches, an organic phosphorus agent, a carbamate agent, a boron compound, It may be a fluorine compound or a neonicotinoid compound such as clothianidin for preventing white ants from being damaged.

次に、以上の構成からなる合成樹脂製の管1の作用効果について説明する。この合成樹脂製の管1によると、管1の内面側に露出する防虫層2が、管1の長手方向に断続的に形成されている。こうして、管1の内面側に防虫層2が断続的に設けられることで、虫が、管1の内面に沿って進もうとするのが防止され、しかも、使用する防虫成分の量が少なくてすむ。すなわち、管1の内面側に、防虫層2を、長手方向に断続的に設けることで、防虫効果を維持したまま、使用する防虫成分の量を少なくすることができ、これによって、簡単かつ安価に、虫の侵入を防止することができる。   Next, the effect of the synthetic resin pipe 1 having the above-described configuration will be described. According to the tube 1 made of synthetic resin, the insect repellent layer 2 exposed on the inner surface side of the tube 1 is formed intermittently in the longitudinal direction of the tube 1. Thus, the insect repellent layer 2 is intermittently provided on the inner surface side of the tube 1 to prevent the insects from trying to move along the inner surface of the tube 1 and the amount of the insect repellent component to be used is small. I'm sorry. That is, by providing the insect repellent layer 2 on the inner surface side of the tube 1 intermittently in the longitudinal direction, the amount of the insect repellent component to be used can be reduced while maintaining the insect repellent effect. In addition, insects can be prevented from entering.

図2は、本発明の第二の実施の形態を示す。この実施の形態は、第一の実施の形態とは、防虫層2および非防虫層3に代えて、それとは構成の異なる防虫層12および非防虫層13が用いられ、さらに、外層14が付加される点が異なるが、他は同様である。   FIG. 2 shows a second embodiment of the present invention. In this embodiment, in place of the insect repellent layer 2 and the non-insect repellent layer 3, different insect repellent layers 12 and non-insect repellent layers 13 are used, and an outer layer 14 is added. The other points are the same.

この合成樹脂製の管11は、防虫成分を含有する防虫層12と、防虫成分を含有しない非防虫層13とが、管11の内面側に露出するようにして管11の長手方向に交互に形成される。これにより、防虫層12が、管11の内面側に露出するようにして管11の長手方向に断続的に形成される。そして、図示実施の形態においては、これら防虫層12および非防虫層13の外側に、外層14が設けられる。   This tube 11 made of synthetic resin is alternately arranged in the longitudinal direction of the tube 11 so that the insect-repellent layer 12 containing the insect-repellent component and the non-insect-repellent layer 13 containing no insect-repellent component are exposed on the inner surface side of the tube 11 It is formed. Thereby, the insect repellent layer 12 is intermittently formed in the longitudinal direction of the tube 11 so as to be exposed on the inner surface side of the tube 11. In the illustrated embodiment, an outer layer 14 is provided outside the insect-proof layer 12 and the non-insect-proof layer 13.

具体的には、防虫層12および非防虫層13は、例えば、塩化ビニル樹脂とかポリエチレン樹脂とかナイロン樹脂等の合成樹脂材料によって形成される。そして、防虫層12は、防虫成分(詳しくは、マイクロカプセルに封入された防虫成分)が、ベースとなる合成樹脂材料とともに混練されて成形される。   Specifically, the insect-proof layer 12 and the non-insect-proof layer 13 are formed of a synthetic resin material such as a vinyl chloride resin, a polyethylene resin, or a nylon resin. The insect repellent layer 12 is formed by kneading an insect repellent component (specifically, an insect repellent component enclosed in a microcapsule) together with a synthetic resin material as a base.

また、外層14は、例えばカプサイシン類からなる防鼠成分を含有する。詳細には、外層14は、防鼠成分(詳しくは、マイクロカプセルに封入された防鼠成分)が、ベースとなる塩化ビニル樹脂とかポリエチレン樹脂とかナイロン樹脂等の合成樹脂材料とともに混練されて成形される。   Moreover, the outer layer 14 contains an antifungal component made of, for example, capsaicin. Specifically, the outer layer 14 is formed by kneading a fender component (specifically, a fender component enclosed in a microcapsule) with a synthetic resin material such as a vinyl chloride resin, a polyethylene resin, or a nylon resin as a base. The

以上の構成により、この合成樹脂製の管11は、管11の内面側に露出する防虫層12が、管11の長手方向に断続的に形成され、これにより、この管11は、第一の実施の形態に示す合成樹脂製の管1と同様の作用効果を有する。   With this structure, the synthetic resin pipe 11 has the insect repellent layer 12 exposed on the inner surface side of the pipe 11 formed intermittently in the longitudinal direction of the pipe 11. It has the same effect as the synthetic resin pipe 1 shown in the embodiment.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、管1、11は、配線・配管材を収容保護する管でなくとも、エアコン用のドレンホース等であってもよい。   In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the pipes 1 and 11 may be a drain hose or the like for an air conditioner, instead of a pipe that accommodates and protects wiring and piping materials.

また、管1、11は、波付管からなるが、この波付管は、その波を構成する凹部および凸部が、リング状に形成される以外に、螺旋状に形成されてもよい。また、この管1、11は、波付管でなくても、平滑管であってもよく、また、この管1、11は、可撓性を備える管(可撓管)でなくとも、硬質管であってもよい。   Moreover, although the pipe | tubes 1 and 11 consist of a corrugated pipe | tube, this corrugated pipe | tube may be formed helically in addition to the recessed part and convex part which comprise the wave being formed in a ring shape. The tubes 1 and 11 may not be corrugated tubes or may be smooth tubes. The tubes 1 and 11 may be rigid even if they are not flexible tubes (flexible tubes). It may be a tube.

また、第一の実施の形態において、防虫層2は、非防虫層3の内面に、防虫成分を含有する防虫剤が塗布されてその防虫剤が硬化して被膜化されて形成されるが、この防虫層2は、防虫成分が、ベースとなる塩化ビニル樹脂とかポリエチレン樹脂とかナイロン樹脂等の合成樹脂材料とともに混練されて成形されてもよい。   In the first embodiment, the insect repellent layer 2 is formed by coating the inner surface of the non-insect repellent layer 3 with a repellent containing an insect repellent and curing the repellent, This insect repellent layer 2 may be formed by kneading an insect repellent component together with a synthetic resin material such as vinyl chloride resin, polyethylene resin or nylon resin as a base.

また、第二の実施の形態において、管11の外層14は、防鼠成分を含有するが、この防鼠成分を含有しなくともよい。また、この外層14は、無くともよい。   Moreover, in 2nd Embodiment, although the outer layer 14 of the pipe | tube 11 contains a fender component, it does not need to contain this fender component. Further, the outer layer 14 may be omitted.

また、防虫層2、12が含有する防虫成分は、隣り合う防虫層で、同じ防虫成分である必要はなく、異なる防虫成分であってもよい。   Further, the insect repellent components contained in the insect repellent layers 2 and 12 are not necessarily the same insect repellent component in adjacent insect repellent layers, and may be different insect repellent components.
