  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, at least the first insect repellent part 2a containing the first insect repellent component and the second insect repellent part 2b containing the second insect repellent component different from the first insect repellent component are included in the tube 1 on the inner surface side of the tube 1 In FIG. 2, the electrodes are exposed repeatedly in the longitudinal direction.

  Specifically, the tube 1 includes the first insect repellent layer 3a containing the first insect repellent component and continuously formed in the longitudinal direction of the tube 1, and the first insect repellent layer 3a containing the second insect repellent component. And a second insect repellent layer 3 b formed intermittently in the longitudinal direction of the tube 1. Therefore, the portion of the first insect repellent layer 3a exposed to the inside of the tube 1 becomes the first insect repellent portion 2a, and the second insect repellent layer 3b becomes the second insect repellent portion 2b as it is.

  In addition, the tube 1 is provided with a fungicide component on the outer surface side of the tube 1 outside the first insect repellent portion 2a and the second insect repellent portion 2b (in the illustrated embodiment, on the outside of the first insect repellent layer 3a). An anti-mold layer 4 is provided. And the pipe | tube 1 is provided with the cover layer 5 used as the outermost layer on the outer side rather than the fender layer 4, and the cover layer 5 contains an ant-proof component.

  Specifically, the tube 1 is a corrugated tube having flexibility. And the pipe | tube 1 consists of a three-layer pipe | tube of the 1st insect repellent layer 3a, the fungicide layer 4, and the cover layer 5, but has a four-layer structure where the 2nd insect repellent layer 3b was added partially. Have.

  In the first insect repellent layer 3a, for example, a first insect repellent component (specifically, a first insect repellent component enclosed in a microcapsule) is kneaded together with a synthetic resin material such as a vinyl chloride resin, a polyethylene resin, or a nylon resin as a base. To be molded.

  The second insect repellent layer 3b is formed by applying an insect repellent containing the second insect repellent component to the inner surface of the first insect repellent layer 3a and curing the insect repellent to form a film. This insect repellent is, for example, a mixture of a second insect repellent component in, for example, a synthetic resin, and more specifically includes a binder resin, a volatile solvent, and a second insect repellent component, and the volatile solvent is volatilized after application. By doing so, the insect repellent is cured to form a film.

  The fender layer 4 is formed by kneading a fender component (specifically, a fender component enclosed in microcapsules) with a synthetic resin material such as vinyl chloride resin, polyethylene resin, or nylon resin as a base.

  The cover layer 5 is molded by kneading an ant-proof component (specifically, an ant-proof component enclosed in a microcapsule) together with a synthetic resin material such as a vinyl chloride resin, a polyethylene resin, or a nylon resin as a base. However, in the illustrated embodiment, the cover layer 5 contains an antifungal component together with an antifungal component. Therefore, the cover layer 5 is based on an antifungal component (specifically, an antifungal component enclosed in a microcapsule) and an antifungal component (specifically, an antifungal component enclosed in a microcapsule). It is kneaded and molded together with a synthetic resin material such as vinyl chloride resin, polyethylene resin or nylon resin. And the content rate of the fender component in this cover layer 5 is smaller than the content rate of the fender component in the fender layer 4.

  By the way, the first insect repellent component is an insect repellent component (that is, an ant repellent component) for preventing white ants from being damaged, and is composed of, for example, a neonicotinoid compound such as clothianidin. The second insect repellent component is an insect repellent component for preventing insects (such as cockroaches, centipedes, and other insects) different from white ants, and is made of, for example, a pyrethroid compound that has a high insect repellent effect on cockroaches. And the fender component in the fender layer 4 or the fender component in the cover layer 5 consists of capsaicins. Here, the content of the fender component in the fender layer 4 is preferably, for example, 1 to 2% by weight, and the content of the fender component in the cover layer 5 is, for example, 0.1 to 0.5. It is desirable that the amount be% by weight. Moreover, the ant-proof component in the cover layer 5 consists of neonicotinoid type compounds, such as clothianidin, like the said 1st insect-control component.

  Next, the effect of the synthetic resin pipe 1 according to the first embodiment will be described. According to this synthetic resin pipe 1, at least the first insect repellent part 2a and the second insect repellent part 2b (in the illustrated embodiment, the first insect repellent part 2a and the second insect repellent part 2b) Exposed side by side in the longitudinal direction on the inner surface side. Here, since the insect repellent component of the first insect repellent portion 2a and the insect repellent component of the second insect repellent portion 2b are different, it is possible to prevent at least two kinds of insects from moving along the inner surface of the tube 1. The insect-repellent effect can be exerted against these insects. That is, according to this synthetic resin pipe 1, at least the first insect repellent part 2a and the second insect repellent part 2b (in the illustrated embodiment, the first insect repellent part 2a and the second insect repellent part 2b), By exposing repeatedly in the longitudinal direction on the inner surface side of the tube 1, an insecticidal effect can be exerted against a plurality of types of insects.

By intermittently ejecting the above-mentioned insect repellent containing the inside, the second insect repellent layer 3b can be formed by applying the insect repellent to the inner surface of the tube body. Thus, since the tube 1 is manufactured by ejecting the insect repellent into the tube body at the time of forming the tube main body, the tube 1 can be easily manufactured, and the insect repellent (that is, the second insect repellent layer 3b), The adhesion to the tube body can be enhanced.

  FIG. 2 shows a second embodiment of the present invention. In this embodiment, instead of the first insect repellent layer 3a and the second insect repellent layer 3b, the first insect repellent layer 13a and the second insect repellent layer 13b having different configurations from that of the first embodiment are used. Moreover, although the point which is not provided with the cover part 5 is different, others are the same, and below, the same code | symbol is attached | subjected to the same site | part and a different part is mainly demonstrated.

  In the tube 1 made of synthetic resin, a first insect repellent layer 13 a containing a first insect repellent component and a second insect repellent layer 13 b containing a second insect repellent component different from the first insect repellent component are arranged in the longitudinal direction of the tube 1. The first insect repellent layer 13a itself becomes the first insect repellent portion 2a exposed to the inside of the tube 1 and the second insect repellent layer 13b itself is exposed to the inside of the tube 1 thereby. 2 It becomes insect repellent part 2b.

  Here, the first insect repellent layer 13a is made of, for example, a synthetic resin material such as a vinyl chloride resin, a polyethylene resin, or a nylon resin in which the first insect repellent component (specifically, the first insect repellent component enclosed in the microcapsule) is a base. Kneaded together and molded. Similarly, the second insect repellent layer 13b is made of, for example, a synthetic resin material such as a vinyl chloride resin, a polyethylene resin, or a nylon resin in which the second insect repellent component (specifically, the second insect repellent component enclosed in the microcapsule) is a base.

A fender layer 4 is provided, and in the illustrated embodiment, this fender layer 4 is the outermost layer of the tube 1. And this pipe | tube 1 is formed with the 1st insect repellent layer 13a, the 2nd insect repellent layer 13b, and the fender layer 4 by blow molding.

  The effect of the synthetic resin tube 1 according to the second embodiment is the same as that of the first embodiment, and is the first insect repellent part 2a (first insect repellent layer 13a) and the second insect repellent part 2b. The (second insect repellent layer 13b) is repeatedly exposed in the longitudinal direction on the inner surface side of the tube 1. Here, since the insect repellent component of the first insect repellent portion 2a and the insect repellent component of the second insect repellent portion 2b are different, it is possible to prevent at least two kinds of insects from moving along the inner surface of the tube 1. The insect-repellent effect can be exerted against these insects. That is, according to the tube 1 made of this synthetic resin, the first insect repellent portion 2a and the second insect repellent portion 2b are repeatedly exposed in the longitudinal direction on the inner surface side of the tube 1 so that a plurality of types of insects can be prevented. Insect repellent effect.

  Moreover, this pipe | tube 1 equips the outer surface side with the fender layer 4 containing a fungicide component, so that this pipe | tube 1 can exhibit the fungicide effect in addition to an insecticidal effect.

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, 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 / piping 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.

  The tube 1 is formed such that the first insect repellent portion 2a and the second insect repellent portion 2b are repeatedly exposed in the longitudinal direction on the inner surface side of the tube 1, and the first insect repellent portion 2a and the second insect repellent portion 2b are exposed. The insect repellent portions 2b may not be arranged closely but may be arranged at intervals.

  In addition to the first insect repellent part 2a and the second insect repellent part 2b, the tube 1 includes a third insect repellent part containing a third insect repellent component different from the first insect repellent component and the second insect repellent component, The first insect repellent part, the second insect repellent part, and the third insect repellent part may be formed so as to be repeatedly exposed in the longitudinal direction on the inner surface side of the tube 1. Here, the arrangement order of the first insect repellent part, the second insect repellent part, and the third insect repellent part is as follows: ABC is the order of the first insect repellent part A, the second insect repellent part B, and the third insect repellent part C. For example, the order may be ABAC. Moreover, the pipe | tube 1 may be provided with not only these three types of insect-proof parts but four or more types of insect-proof parts.

  In the first embodiment, the cover layer 5 contains an antifungal component in addition to the antifungal component, but this antifungal component may not be contained.

That is, the pipe 1 is provided with the cover layer 5 which is the outermost layer outside the first insect-proofing part 2a and the second insect-proofing part 2b, without having the fender-proofing layer 4, and the covering layer 5 contains an ant-proofing component. May be. However, the tube 1 may not have the cover layer 5 in addition to the fender layer 4.

  Similarly, in the second embodiment, the tube 1 includes the fender layer 4, but this fender layer 4 may be omitted. In this case, as in the first embodiment, the tube 1 is provided with a cover layer that is an outermost layer outside the first insect repellent part 2a and the second insect repellent part 2b, and the cover layer is provided with a protective layer. An ant component may be contained.

  In the first embodiment, the second insect repellent layer 3b is formed by coating the inner surface of the first insect repellent layer 3a with an insect repellent containing the second insect repellent component and curing the insect repellent. Although formed, the second insect repellent layer 3b may be formed by kneading the second insect repellent component together with a synthetic resin material such as vinyl chloride resin, polyethylene resin or nylon resin as a base. That is, the tube 1 may be entirely formed by blow molding of the first insect repellent layer 3a, the second insect repellent layer 3b, the fender repellent layer 4 and the cover layer 5.

  In the second embodiment, the first insect repellent layer 13a and the second insect repellent layer 13b are 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. However, the first insect repellent layer 13a and the second insect repellent layer 13b are arranged on the inner surface of the outer layer (in the illustrated embodiment, the fender repellent layer 4) on the inner surface of the insect repellent component (in the first insect repellent layer 13a, It may be formed by applying an insect repellent containing 1 insect repellent component and containing a second repellent component in the second insect repellent layer 13b and curing the repellent. Here, the 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 the volatile solvent is volatilized after application. Thus, the insect repellent is formed into a hardened film. In manufacturing the tube 1 made of synthetic resin, a tube body made of the anti-fungal layer 4 is formed by blow molding, and at the time of blow molding, an insect repellent containing a first insect repellent component and a second insect repellent component are added. By alternately ejecting the insect repellents contained therein, the first insect repellent layer 13a and the second insect repellent layer 13b can be formed by applying them to the inner surface of the tube body. Thus, since the tube 1 is manufactured by ejecting the insect repellent into the tube body at the time of forming the tube body, the tube 1 can be easily manufactured, and the insect repellent (that is, the first insect repellent layer 13a and the second insect repellent layer 13a and the second insect repellent layer 13a). The adhesion of the insect repellent layer 13b) to the tube body can be enhanced.

  The first insect repellent component and the second insect repellent component are composed of a neonicotinoid compound or a pyrethroid compound. In addition to these compounds, for example, organic phosphorus agents, carbamate agents, boron compounds, fluorine compounds, etc. It may consist of a component having an insect repellent effect. Accordingly, the first insect repellent component is not limited to the insect repellent component (ant repellent component) for preventing white ants from being damaged. In short, the first insect repellent component and the second insect repellent component may be components different from each other, and the combination thereof is arbitrary. Here, the different components include not only the case where the respective compositions such as the above-mentioned neonicotinoid compounds are different from each other, but also the case where the respective lower compositions belonging to the above composition are different from each other.

  Moreover, in each embodiment shown above or various modifications thereof, the outermost layer of the tube 1 made of synthetic resin may or may not contain an ant-proof component in addition to the case where the latter is included. Even in this case, it is preferable that the outermost layer contains an ant-proof component. In this way, the tube 1 made of synthetic resin contains the ant-proof component in the outermost layer, so that the white ants can be prevented from traveling along the outer surface of the tube 1.

  The outermost layer of the synthetic resin tube 1 preferably contains carbon. As a result, the weather resistance of the tube 1 is improved, and even when the tube 1 is disposed under external light, the tube 1 is prevented from deteriorating and the insecticidal effect or the antifungal effect is prevented from being lowered. can do.
