Abstract

Provided is a synthetic resin tube configured so that the manufacturing cost can be reduced and so that harmful organisms can be controlled on the inside and outside of the tube. A tube 1 consists of a synthetic resin and is provided with a tube wall having an outer layer 2, an inner layer 3, and an intermediate layer 4. Only the outer layer 2 and inner layer 3 of the tube 1, excluding the intermediate layer 4 of the tube 1, comprise control layers (for example, termite control layers for controlling termites) for controlling harmful organisms. The region of the control layers of the tube 1, which increases cost, can be reduced because the intermediate layer 4 is not a control layer.

Description

合成樹脂製の管Plastic tube
　この発明は、有害生物による被害を防ぐことができる合成樹脂製の管に関するものである。 This invention relates to a tube made of synthetic resin that can prevent damage caused by pests.
　従来、有害生物を防除する防除剤としての防蟻剤が混入された、合成樹脂製の波付管（管）があった（例えば、特許文献１参照）。この波付管は、単層構造であったり、外層と内層との二層構造であったりした。そして、単層構造の合成樹脂に、あるいは、二層構造における外層の合成樹脂に、防蟻剤としての、有機リン系化合物とか有機酸金属塩とかが混入された。 Conventionally, there has been a corrugated tube (tube) made of synthetic resin mixed with an anti-bacterial agent as a control agent for controlling pests (see, for example, Patent Document 1). This corrugated tube had a single-layer structure or a two-layer structure of an outer layer and an inner layer. Then, an organophosphorus compound or an organic acid metal salt as an antifungal agent was mixed into the synthetic resin having a single layer structure or the outer layer synthetic resin having a two-layer structure.
実公平６－４６９８９号公報No. 6-46989
　ところで、前記従来の合成樹脂製の波付管（管）にあっては、単層構造の場合には、その単層構造の合成樹脂に混入された防除剤としての防蟻剤が、管全体に広がることから、その濃度を一定以上に保つだけの十分な量の防蟻剤を必要とし、コスト高となっていた。また、波付管が二層構造の場合には、その外層の合成樹脂に防蟻剤が混入されたが、内層の合成樹脂には防蟻剤が混入されないことから、波付管の内側に侵入した白蟻に対しては防蟻の効果を発揮することはできなかった。 By the way, in the conventional corrugated pipe (tube) made of synthetic resin, in the case of a single layer structure, an anti-anticide as a control agent mixed in the synthetic resin of the single layer structure is Therefore, a sufficient amount of an ant-preventing agent is required to keep the concentration at a certain level or more, and the cost is high. In addition, when the corrugated tube has a two-layer structure, the termite-proofing agent is mixed in the outer layer synthetic resin, but the inner layer synthetic resin does not contain the termite-proofing agent. The ant-proof effect could not be exerted against the invading white ants.
　この発明は、上記した従来の欠点を解決するためになされたものであり、その目的とするところは、製造コストを下げることができ、かつ、管の内外において有害生物を防除することができる、合成樹脂製の管を提供することにある。 The present invention has been made to solve the above-described conventional drawbacks, and the object of the present invention is to reduce the manufacturing cost and to control pests inside and outside the pipe. The object is to provide a tube made of synthetic resin.
　この発明に係る合成樹脂製の管は、前記目的を達成するために、次の構成からなる。すなわち、
　本発明に係る一実施形態の合成樹脂製の管は、外層、内層および中間層を有する管壁を備える、合成樹脂製の管であって、前記中間層を除く前記外層および前記内層のみが、有害生物を防除する防除層からなる。 In order to achieve the object, the synthetic resin pipe according to the present invention has the following configuration. That is,
A synthetic resin tube according to an embodiment of the present invention is a synthetic resin tube including a tube wall having an outer layer, an inner layer, and an intermediate layer, and only the outer layer and the inner layer excluding the intermediate layer, It consists of a control layer that controls pests.
　この合成樹脂製の管によると、外層と内層が、有害生物を防除する防除層からなることで、管の内外において有害生物を防除することができる。そして、中間層が、防除層でないことから、管におけるコスト高となる防除層の領域を減らすことができる。 According to this synthetic resin tube, the outer layer and the inner layer are composed of a control layer for controlling pests, whereby pests can be controlled inside and outside the tube. And since an intermediate | middle layer is not a prevention layer, the area | region of the prevention layer which becomes the high cost in a pipe | tube can be reduced.
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記外層および前記内層は、前記防除層としての防蟻層からなり、それら防蟻層は、ナイロン樹脂によって形成されてもよい。こうして、ナイロン樹脂によって形成された外層および内層は、硬く、白蟻がこの外層や内層を容易には食い破ることができない。 Further, according to the synthetic resin pipe of a further embodiment of the present invention, the outer layer and the inner layer are formed of an ant barrier layer as the control layer, and the ant barrier layer may be formed of a nylon resin. . Thus, the outer layer and the inner layer formed of nylon resin are hard, and white ants cannot easily break through the outer layer and the inner layer.
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記外層および前記内層は、前記防除層としての防蟻層からなり、それら防蟻層は、ポリオレフィン系樹脂に滑剤を添加して形成されてもよい。こうして、ポリオレフィン系樹脂に滑剤を添加して形成された外層および内層の表面は、滑り易く、白蟻がこの外層や内層を容易には食い破ることができない。 According to the synthetic resin tube of a further embodiment of the present invention, the outer layer and the inner layer are formed of an ant barrier layer as the control layer, and the ant barrier layer is formed by adding a lubricant to the polyolefin resin. May be formed. Thus, the surface of the outer layer and the inner layer formed by adding the lubricant to the polyolefin resin is slippery, and white ants cannot easily break through the outer layer and the inner layer.
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記外層および前記内層は、前記防除層としての防蟻層からなり、それら防蟻層は、防蟻剤を含有して形成されてもよい。こうして、外層および内層が、防蟻剤を含有して形成されることで、白蟻が、管の外面とか内面伝いに進行して家屋等に侵入したり、管の外層や内層を食い破ったりするのを防ぐことができる。 Further, according to the synthetic resin tube of a further embodiment of the present invention, the outer layer and the inner layer are formed of an ant-proof layer as the control layer, and these ant-proof layers are formed by containing an ant-proof agent. May be. In this way, the outer layer and the inner layer are formed by containing the ant-proofing agent, so that the white ants progress along the outer surface or the inner surface of the tube and enter a house or the like, and eat and break the outer layer and the inner layer of the tube. Can be prevented.
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記外層および前記内層は、前記防除層としての防蟻層からなり、前記外層となる防蟻層は、ナイロン樹脂によって形成され、あるいは、ポリオレフィン系樹脂に滑剤を添加して形成され、前記内層となる防蟻層は、防蟻剤を含有して形成されてもよい。こうして、ナイロン樹脂によって形成された外層の場合は、その外層は、硬く、白蟻がその外層を容易には食い破ることができず、ポリオレフィン系樹脂に滑剤を添加して形成された外層の場合は、その外層の表面は、滑り易く、白蟻がその外層を容易には食い破ることができない。そして、内層が、防蟻剤を含有して形成されることで、白蟻が、管の内面伝いに進行して家屋等に侵入したり、管の内層を食い破ったりするのを防ぐことができる。 According to the synthetic resin pipe of a further embodiment of the present invention, the outer layer and the inner layer are formed of an ant-proof layer as the control layer, and the ant-proof layer serving as the outer layer is formed of a nylon resin. Alternatively, it may be formed by adding a lubricant to a polyolefin-based resin, and the ant-proof layer serving as the inner layer may be formed containing an ant-proof agent. Thus, in the case of an outer layer formed of a nylon resin, the outer layer is hard, and white ants cannot easily break through the outer layer. In the case of an outer layer formed by adding a lubricant to a polyolefin-based resin, The surface of the outer layer is slippery, and white ants cannot easily break through the outer layer. And, since the inner layer is formed to contain an ant-proofing agent, it is possible to prevent white ants from propagating along the inner surface of the pipe and entering a house or the like, or eroding the inner layer of the pipe. .
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記外層の肉厚と前記内層の肉厚は、それぞれ、前記中間層の肉厚と同一またはそれより薄くなっていてもよい。こうして、防除層からなる外層および内層の肉厚を制限することで、管における防除層の領域を確実に減らすことができる。 Further, according to the synthetic resin pipe of a further embodiment of the present invention, the thickness of the outer layer and the thickness of the inner layer may be the same as or thinner than the thickness of the intermediate layer, respectively. . Thus, by limiting the thickness of the outer layer and the inner layer made of the control layer, the region of the control layer in the pipe can be surely reduced.
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記内層の肉厚は、前記中間層の肉厚と同一またはそれより薄く、前記外層の肉厚は、前記内層の肉厚と同一またはそれより薄くなっていてもよい。こうして、防除層からなる外層および内層の肉厚を制限することで、管におけるコスト高となる防除層の領域を確実に減らすことができる。 Further, according to the synthetic resin pipe of a further embodiment of the present invention, the inner layer has a wall thickness equal to or less than that of the intermediate layer, and the outer layer has a wall thickness of the inner layer. It may be the same as or thinner than that. In this way, by limiting the thickness of the outer layer and the inner layer made of the control layer, it is possible to reliably reduce the region of the control layer that increases the cost in the pipe.
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記中間層は、複数層からなってもよい。 Further, according to the synthetic resin pipe of a further embodiment of the present invention, the intermediate layer may be composed of a plurality of layers.
　また、本発明のさらなる実施形態の合成樹脂製の管によれば、前記外層には、カーボンが含有されてもよい。これにより、管は、耐紫外線特性が向上し、管が、外光下に配設された場合であっても、その管の劣化を防いで、外層における有害生物を防除する防除効果の低下を防止することができる。 Moreover, according to the synthetic resin tube of a further embodiment of the present invention, the outer layer may contain carbon. As a result, the tube has improved UV resistance, and even when the tube is placed under external light, the tube is prevented from deteriorating and the control effect of controlling pests in the outer layer is reduced. Can be prevented.
　この発明に係る合成樹脂製の管によれば、中間層を除く外層および内層のみが、有害生物を防除する防除層からなることで、管におけるコスト高となる防除層の領域を減らして製造コストを下げることができ、かつ、管の内外において有害生物を防除することができる。 According to the synthetic resin pipe according to the present invention, only the outer layer and the inner layer excluding the intermediate layer are formed of the control layer for controlling pests, thereby reducing the area of the control layer that increases the cost of the pipe and the manufacturing cost. And can control pests inside and outside the tube.

　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、外層２、内層３および中間層４を有する管壁を備える。そして、管１は、中間層４を除く外層２および内層３のみが、有害生物を防除する防除層からなる。 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 includes a tube wall having an outer layer 2, an inner layer 3 and an intermediate layer 4. And the pipe | tube 1 consists of a control layer which only the outer layer 2 and the inner layer 3 except the intermediate | middle layer 4 control a pest.
　ここで、外層２の肉厚と内層３の肉厚は、それぞれ、中間層４の肉厚と同一またはそれより薄くなっている。詳細には、内層３の肉厚は、中間層４の肉厚と同一またはそれより薄く、外層２の肉厚は、内層３の肉厚と同一またはそれより薄くなっている。すなわち、内層３は、管１に配線・配管材を挿通する際の内面の擦り傷の深さが中間層４に達することがないだけの肉厚を有すればよく、その肉厚は、中間層４の肉厚と同一またはそれより薄くて構わない。そして、管１の外面（外層２の表面）は、内面（内層３の表面）ほどは傷付くことはなく、このため、外層２の肉厚は、内層３の肉厚と同一またはそれより薄くて構わない。 Here, the thickness of the outer layer 2 and the thickness of the inner layer 3 are the same as or thinner than the thickness of the intermediate layer 4, respectively. Specifically, the thickness of the inner layer 3 is equal to or less than the thickness of the intermediate layer 4, and the thickness of the outer layer 2 is equal to or less than the thickness of the inner layer 3. That is, the inner layer 3 only needs to have a thickness such that the depth of scratches on the inner surface when the wiring / pipe material is inserted into the tube 1 does not reach the intermediate layer 4. It may be the same as or thinner than the thickness of 4. The outer surface of the tube 1 (the surface of the outer layer 2) is not damaged as much as the inner surface (the surface of the inner layer 3). For this reason, the thickness of the outer layer 2 is the same as or thinner than that of the inner layer 3. It doesn't matter.
　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、管壁が、外層２と内層３と中間層４との三層からなる。 Specifically, the tube 1 is a corrugated tube having flexibility. And the pipe | tube 1 consists of three layers, the outer wall 2, the inner layer 3, and the intermediate | middle layer 4, in the pipe wall.
　外層２および内層３（つまり、防除層）は、有害生物を防除する防除剤を含有して形成される。詳細には、外層２と内層３は、それぞれ、有害生物を防除する防除剤が、例えばマイクロカプセルに封入されされて、ベースとなる塩化ビニル樹脂とかポリエチレ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。そして、外層２には、カーボンが含有される。一方、中間層４は、有害生物を防除する防除剤を含有することなく、塩化ビニル樹脂とかポリエチレン樹脂等の合成樹脂材料により成形される。 The outer layer 2 and the inner layer 3 (that is, the control layer) are formed by containing a control agent for controlling pests. Specifically, the outer layer 2 and the inner layer 3 are each molded with a control agent for controlling pests, for example, enclosed in microcapsules and kneaded with a synthetic resin material such as vinyl chloride resin or polyethylene resin as a base. Is done. The outer layer 2 contains carbon. On the other hand, the intermediate layer 4 is formed of a synthetic resin material such as a vinyl chloride resin or a polyethylene resin without containing a control agent for controlling pests.
　ところで、外層２および内層３における前記防除剤は、白蟻の食害を防ぐための防虫剤、つまり防蟻剤であって、その防蟻剤の成分は、例えば、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、また、ピレスロイド系化合物、有機リン剤、カーバメート剤、ホウ素化合物、あるいはフッ素化合物等であったりする。すなわち、外層２および内層３は、防除層としての防蟻層からなり、それら防蟻層は、防蟻剤を含有して形成される。 By the way, the control agent in the outer layer 2 and the inner layer 3 is an insect repellent for preventing white ants from being damaged, that is, an ant repellent, and the component of the ant repellent is, for example, a neonicotinoid compound such as clothianidin. Or a pyrethroid compound, an organic phosphorus agent, a carbamate agent, a boron compound, a fluorine compound, or the like. That is, the outer layer 2 and the inner layer 3 are made of an ant-proof layer as a control layer, and these ant-proof layers are formed containing an ant-proof agent.
　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、外層２と内層３が、有害生物を防除する防除層からなることで、管１の内外において有害生物を防除することができる。そして、中間層４が、防除層でないことから、管１におけるコスト高となる防除層の領域を減らすことができる。すなわち、この合成樹脂製の管１によれば、中間層４を除く外層２および内層３のみが、有害生物を防除する防除層からなることで、管１におけるコスト高となる防除層の領域を減らして製造コストを下げることができ、かつ、管１の内外において有害生物を防除することができる。 Next, the function and effect of the synthetic resin pipe 1 having the above configuration will be described. According to the tube 1 made of synthetic resin, the outer layer 2 and the inner layer 3 are formed of a control layer for controlling pests, whereby pests can be controlled inside and outside the tube 1. And since the intermediate | middle layer 4 is not a control layer, the area | region of the control layer which becomes the high cost in the pipe | tube 1 can be reduced. That is, according to the tube 1 made of synthetic resin, only the outer layer 2 and the inner layer 3 except the intermediate layer 4 are formed of the control layer for controlling pests, thereby increasing the cost of the control layer in the tube 1. The production cost can be reduced by reducing the amount, and pests can be controlled inside and outside the pipe 1.
　また、外層２および内層３が、防除剤としての防蟻剤を含有して形成されることで、白蟻が、管１の外面とか内面伝いに進行して家屋等に侵入したり、管１の外層２や内層３を食い破ったりするのを防ぐことができる。 Further, by forming the outer layer 2 and the inner layer 3 containing an ant control agent as a control agent, the white ants progress along the outer surface or the inner surface of the tube 1 and enter the house or the like. It is possible to prevent the outer layer 2 and the inner layer 3 from being broken.
　また、外層２および内層３の肉厚は、それぞれ、中間層４の肉厚と同一またはそれより薄くなっていたり、内層３の肉厚は、中間層４の肉厚と同一またはそれより薄く、外層２の肉厚は、内層３の肉厚と同一またはそれより薄くなっている。こうして、防蟻層（防除層）からなる外層２および内層３の肉厚を制限することで、管１におけるコスト高となる防蟻層（防除層）の領域を確実に減らすことができる。 Further, the thickness of the outer layer 2 and the inner layer 3 is the same as or thinner than the thickness of the intermediate layer 4, or the thickness of the inner layer 3 is the same as or thinner than the thickness of the intermediate layer 4, The thickness of the outer layer 2 is the same as or thinner than the thickness of the inner layer 3. In this way, by limiting the thickness of the outer layer 2 and the inner layer 3 made of the ant-proof layer (control layer), the area of the ant-control layer (control layer) that increases the cost in the pipe 1 can be surely reduced.
　また、外層２には、カーボンが含有される。このため、管１は、耐紫外線特性が向上し、管１が、外光下に配設された場合であっても、その管１の劣化を防いで、外層２における白蟻を防除する防蟻効果（有害生物を防除する防除効果）の低下を防止することができる。 Further, the outer layer 2 contains carbon. For this reason, the tube 1 has improved anti-ultraviolet characteristics, and even when the tube 1 is disposed under external light, the tube 1 prevents deterioration of the tube 1 and controls white ants in the outer layer 2. Decrease in effect (control effect for controlling pests) can be prevented.
　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、外層２および内層３における防除剤は、有害生物を防除するものであればよく、防蟻剤に限らず、防虫剤であったり、例えばカプサイシン類等を成分とする防鼠剤、その他の薬剤であってもよい。すなわち、防除層は、防蟻層でなくとも、防虫層であったり防鼠層等であったりしてもよい。 Note that the present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the control agent in the outer layer 2 and the inner layer 3 may be anything that controls pests, and is not limited to an anti-anticide, but is an insecticide, for example, an antifungal agent containing capsaicins, etc. It may be a drug. That is, the insect control layer may be an insect repellent layer or an antifungal layer, etc., instead of the ant preventive layer.
　また、外層２と内層３（つまり、防除層）は、それぞれ、有害生物を防除する防除剤が、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が、その他に、外層２と内層３の両方、あるいはいずれか一方は、中間層４の外面とか内面に、防除剤を含有する塗布液が塗布されてその塗布液が硬化して被膜化されて形成されてもよい。ここで、塗布液は、例えば合成樹脂等に防除剤を混合したもの、詳細には、バインダー樹脂と揮発性溶剤と防除剤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、塗布液は、硬化して被膜化される。そして、この合成樹脂製の管１の製造にあたっては、中間層４を含む管本体を、ブロー成形により形成し、そのブロー成形時に、前記塗布液を外部とか内部に噴出することにより、塗布液を管本体の外面とか内面に塗布して、外層２とか内層３を形成することができる。 The outer layer 2 and the inner layer 3 (that is, the control layer) are formed by kneading a control agent for controlling pests together with a synthetic resin material as a base. Both or either one may be formed by applying a coating solution containing a control agent to the outer surface or the inner surface of the intermediate layer 4 and curing the coating solution to form a film. Here, the coating liquid is, for example, a mixture of a control agent in a synthetic resin or the like, and specifically includes a binder resin, a volatile solvent, and a control agent, and the volatile solvent is volatilized after application. The coating solution is cured to form a film. In manufacturing the synthetic resin pipe 1, the pipe body including the intermediate layer 4 is formed by blow molding, and at the time of the blow molding, the coating liquid is sprayed to the outside or the inside to thereby apply the coating liquid. The outer layer 2 or the inner layer 3 can be formed by applying to the outer surface or inner surface of the tube body.
　また、外層２および内層３は、防除層としての防蟻層からなるが、これら防蟻層は、ナイロン樹脂によって形成されてもよい。すなわち、ナイロン樹脂によって形成された外層２および内層３は、硬く、白蟻がこの外層２や内層３を容易には食い破ることができない。ここで、仮に、管１の外側から、白蟻が外層２と中間層４とを食い破ることができたとしても、その内側にある内層３が防蟻層であることから、白蟻によるさらなる侵食をくい止めることができる。こうして、外層２と内層３が、白蟻（有害生物）を防除する防蟻層（防除層）からなることで、管１の内外において白蟻を防除することができる。そして、中間層４が、防蟻層（防除層）でないことから、管１におけるコスト高となる防蟻層の領域を減らすことができる。すなわち、この合成樹脂製の管１によれば、中間層４を除く外層２および内層３のみが、白蟻（有害生物）を防除する防蟻層（防除層）からなることで、管１におけるコスト高となる防蟻層の領域を減らして製造コストを下げることができ、かつ、管１の内外において白蟻を防除することができる。また、外層２および内層３のみがナイロン樹脂によって形成されることで、管１の全体がナイロン樹脂で形成される場合よりも、管１の可撓性を高めることができる。また、外層２となる防蟻層（防除層）が、防蟻剤（防除剤）を含有しなければ、その防蟻剤（防除剤）が土壌等に溶け出す虞がない。 Further, the outer layer 2 and the inner layer 3 are made of ant-proof layers as control layers, but these ant-proof layers may be formed of nylon resin. That is, the outer layer 2 and the inner layer 3 made of nylon resin are hard, and white ants cannot easily break through the outer layer 2 and the inner layer 3. Here, even if the white ants could break through the outer layer 2 and the intermediate layer 4 from the outside of the tube 1, the inner layer 3 on the inner side is an ant-proof layer, so that further erosion by the white ants would occur. I can stop. Thus, the white ants can be controlled inside and outside the pipe 1 by the outer layer 2 and the inner layer 3 being made of ant protection layers (control layers) that control the white ants (pests). And since the intermediate | middle layer 4 is not an ant-proof layer (control layer), the area | region of the ant-proof layer which becomes high cost in the pipe | tube 1 can be reduced. That is, according to the tube 1 made of synthetic resin, only the outer layer 2 and the inner layer 3 except the intermediate layer 4 are formed of an ant protection layer (control layer) that controls white ants (pests), thereby reducing the cost of the tube 1. It is possible to reduce the manufacturing cost by reducing the area of the high ant protection layer, and to control white ants inside and outside the pipe 1. In addition, since only the outer layer 2 and the inner layer 3 are formed of nylon resin, the flexibility of the tube 1 can be improved as compared with the case where the entire tube 1 is formed of nylon resin. Moreover, if the ant-proof layer (control layer) used as the outer layer 2 does not contain an ant-control agent (control agent), there is no possibility that the ant-control agent (control agent) will melt into soil or the like.
　また、外層２および内層３となる防蟻層は、ポリオレフィン系樹脂に滑剤を添加して形成されてもよい。すなわち、ポリオレフィン系樹脂に滑剤を添加して形成された外層２および内層３の表面は、滑り易く、白蟻がこの外層２や内層３を容易には食い破ることができない。ここで、仮に、管１の外側から、白蟻が外層２と中間層４とを食い破ることができたとしても、その内側にある内層３が防蟻層であることから、白蟻によるさらなる侵食をくい止めることができる。こうして、外層２と内層３が、白蟻（有害生物）を防除する防蟻層（防除層）からなることで、管１の内外において白蟻を防除することができる。そして、中間層４が、防蟻層（防除層）でないことから、管１におけるコスト高となる防蟻層の領域を減らすことができる。すなわち、この合成樹脂製の管１によれば、中間層４を除く外層２および内層３のみが、白蟻（有害生物）を防除する防蟻層（防除層）からなることで、管１におけるコスト高となる防蟻層の領域を減らして製造コストを下げることができ、かつ、管１の内外において白蟻を防除することができる。また、外層２となる防蟻層（防除層）が、防蟻剤（防除剤）を含有しなければ、その防蟻剤（防除剤）が土壌等に溶け出す虞がない。ここで、ポリオレフィン系樹脂としては、例えば、ポリエチレン樹脂とかポリプロピレン樹脂等が挙げられるが、それらに限定されるものではない。そして、滑剤としては、例えば、フッ素系とかシリコーン系とか、あるいは脂肪酸アミド系等の滑剤が挙げられるが、それらに限定されるものではないのは勿論である。 Moreover, the ant-proof layer which becomes the outer layer 2 and the inner layer 3 may be formed by adding a lubricant to a polyolefin resin. That is, the surface of the outer layer 2 and the inner layer 3 formed by adding a lubricant to the polyolefin resin is slippery, and white ants cannot easily break through the outer layer 2 and the inner layer 3. Here, even if the white ants could break through the outer layer 2 and the intermediate layer 4 from the outside of the tube 1, the inner layer 3 on the inner side is an ant-proof layer, so that further erosion by the white ants would occur. I can stop. Thus, the white ants can be controlled inside and outside the pipe 1 by the outer layer 2 and the inner layer 3 being made of ant protection layers (control layers) that control the white ants (pests). And since the intermediate | middle layer 4 is not an ant-proof layer (control layer), the area | region of the ant-proof layer which becomes high cost in the pipe | tube 1 can be reduced. That is, according to the tube 1 made of synthetic resin, only the outer layer 2 and the inner layer 3 except the intermediate layer 4 are formed of an ant protection layer (control layer) that controls white ants (pests), thereby reducing the cost of the tube 1. It is possible to reduce the manufacturing cost by reducing the area of the high ant protection layer, and to control white ants inside and outside the pipe 1. Moreover, if the ant-proof layer (control layer) used as the outer layer 2 does not contain an ant-control agent (control agent), there is no possibility that the ant-control agent (control agent) will melt into soil or the like. Here, examples of the polyolefin-based resin include polyethylene resin and polypropylene resin, but are not limited thereto. Examples of the lubricant include, but are not limited to, fluorine-based, silicone-based, or fatty acid amide-based lubricants.
　また、外層２となる防蟻層は、ナイロン樹脂によって形成され、あるいは、ポリオレフィン系樹脂に滑剤を添加して形成され、内層３となる防蟻層は、防蟻剤を含有して形成されてもよい。こうして、ナイロン樹脂によって形成された外層２の場合は、その外層２は、硬く、白蟻がその外層２を容易には食い破ることができず、ポリオレフィン系樹脂に滑剤を添加して形成された外層２の場合は、その外層２の表面は、滑り易く、白蟻がその外層２を容易には食い破ることができない。そして、内層３が、防蟻剤を含有して形成されることで、白蟻が、管１の内面伝いに進行して家屋等に侵入したり、管１の内層３を食い破ったりするのを防ぐことができる。ここで、仮に、管１の外側から、白蟻が外層２と中間層４とを食い破ることができたとしても、その内側にある内層３が防蟻層であることから、白蟻によるさらなる侵食をくい止めることができる。こうして、外層２と内層３が、白蟻（有害生物）を防除する防蟻層（防除層）からなることで、管１の内外において白蟻を防除することができる。そして、中間層４が、防蟻層（防除層）でないことから、管１におけるコスト高となる防蟻層の領域を減らすことができる。すなわち、この合成樹脂製の管１によれば、中間層４を除く外層２および内層３のみが、白蟻（有害生物）を防除する防蟻層（防除層）からなることで、管１におけるコスト高となる防蟻層の領域を減らして製造コストを下げることができ、かつ、管１の内外において白蟻を防除することができる。また、内層３が防蟻剤（防除剤）を含有するものの、その防蟻剤は、中間層４に遮られて、外部の土壌等に溶け出す虞がない。つまり、中間層４が、防蟻剤（防除剤）の流出を防止する流出防止層となる。 Moreover, the ant-proof layer used as the outer layer 2 is formed of a nylon resin, or is formed by adding a lubricant to a polyolefin resin, and the ant-proof layer used as the inner layer 3 is formed containing an ant-proof agent. Also good. Thus, in the case of the outer layer 2 formed of a nylon resin, the outer layer 2 is hard, and white ants cannot easily break through the outer layer 2, and the outer layer 2 is formed by adding a lubricant to the polyolefin resin. In the case of 2, the surface of the outer layer 2 is slippery, and white ants cannot easily break through the outer layer 2. And, since the inner layer 3 is formed to contain an ant-proofing agent, the white ants advance along the inner surface of the tube 1 to enter a house or the like, or eat away the inner layer 3 of the tube 1. Can be prevented. Here, even if the white ants could break through the outer layer 2 and the intermediate layer 4 from the outside of the tube 1, the inner layer 3 on the inner side is an ant-proof layer, so that further erosion by the white ants would occur. I can stop. Thus, the white ants can be controlled inside and outside the pipe 1 by the outer layer 2 and the inner layer 3 being made of ant protection layers (control layers) that control the white ants (pests). And since the intermediate | middle layer 4 is not an ant-proof layer (control layer), the area | region of the ant-proof layer which becomes high cost in the pipe | tube 1 can be reduced. That is, according to the tube 1 made of synthetic resin, only the outer layer 2 and the inner layer 3 except the intermediate layer 4 are formed of an ant protection layer (control layer) that controls white ants (pests), thereby reducing the cost of the tube 1. It is possible to reduce the manufacturing cost by reducing the area of the high ant protection layer, and to control white ants inside and outside the pipe 1. Moreover, although the inner layer 3 contains an ant preventive agent (control agent), the ant preventive agent is blocked by the intermediate layer 4 and is not likely to be dissolved into the external soil or the like. That is, the intermediate layer 4 serves as an outflow prevention layer that prevents outflow of the termite-proofing agent (controlling agent).
　また、外層２および内層３における、上述した種々の防蟻層（防除層）は、その組み合わせは任意であり、上述した組み合わせに限定されるものではない。 Further, the various ant protection layers (control layers) described above in the outer layer 2 and the inner layer 3 can be arbitrarily combined, and are not limited to the combinations described above.
　また、外層２および内層３の肉厚は、上述した範囲に限定されるものではないのは勿論である。 Of course, the thickness of the outer layer 2 and the inner layer 3 is not limited to the above-described range.
　また、外層２には、カーボンが含有されるが、このカーボンは、含有されなくともよい。 Further, the outer layer 2 contains carbon, but this carbon may not be contained.
　また、中間層４は、単層でなくとも、材料の異なる複数層からなっていてもよい。 Further, the intermediate layer 4 may not be a single layer but may be composed of a plurality of layers made of different materials.
　また、管１は、配線・配管材を収容保護するものでなくとも、管内に水を流すドレンホース等であってもよい。また、管１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は、波付管でなくとも、平滑管であってもよい。また、管１は、可撓性を備えるが、この可撓性を備えなくともよい。 Further, the pipe 1 may be a drain hose or the like that allows water to flow into the pipe, instead of accommodating and protecting the wiring / pipe material. Moreover, although the pipe | tube 1 consists of a corrugated pipe | tube, this corrugated pipe | tube may be formed in a helical form other than the recessed part and convex part which comprise the wave being formed in a ring shape. The tube 1 may be a smooth tube instead of a corrugated tube. Moreover, although the pipe | tube 1 is provided with flexibility, it is not necessary to provide this flexibility.
