A moth repellent layer is provided in the intermediate layer of the tube wall. At least the outermost layer and the innermost layer of the tube wall are formed of a protective layer that protects the wrinkle repellency layer without containing a foul repellent. The outermost layer is made of synthetic resin. The innermost layer contains an insect repellent.

  According to this tube, the moth repellent layer is provided in the intermediate layer, and the outermost layer and the innermost layer are made of protective layers that protect the moth repellent layer, so that the moth repellent agent of the moth repellent layer is in the hands of humans. There is no adhesion. And since an innermost layer contains an insect repellent, an insect is hard to penetrate | invade in this fender.

  Moreover, like the fender tube according to the second aspect of the present invention, in the fender tube according to the first aspect, the outermost layer may have ultraviolet resistance. Thereby, even if it is a case where a fender tube is arrange | positioned under the external light of the outdoors, the function as a fender tube can be maintained long.

  Further, as in the fender tube according to the third invention, in the fender tube according to claim 1 or 2, the pipe wall penetrates the pipe wall and takes in wiring / pipe material. An enabling slit may be formed.

  Further, in the fender tube according to the third aspect, like the fender tube according to the invention of the fourth aspect, the slit may be formed in a spiral shape with respect to the tube wall.

  According to the fungus tube according to the present invention, the moth repellent layer is provided in the intermediate layer, the outermost layer and the innermost layer are the protective layers, and further, the insect repellent is contained in the innermost layer, so that the moth repellent can be avoided in human hands. It is possible to prevent the agent from adhering, and it is difficult for insects to invade into the fender and the insects can be prevented from entering the building or the like through the fender.

  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the fender pipe | tube based on this invention is demonstrated based on drawing.

  FIG. 1 shows an embodiment of the present invention. Reference numeral 1 in the figure denotes a fender tube, and this fist tube 1 is composed of three or more layers of the tube wall 1a.

  The fender tube 1 is, for example, a tube 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 fender tube 1 includes a fistula repellent layer 2 containing a fistula repellent made of capsaicins on the intermediate layer 1b of the tube wall 1a. At least the outermost layer 1c and the innermost layer 1d of the tube wall 1a are formed of protective layers 3 and 4 that protect the wrinkle repellent layer 2 without containing a wrinkle repellent. The innermost layer 1d contains an insect repellent.

  Specifically, the fender tube 1 is made of a synthetic resin and includes a corrugated tube having flexibility. The fender tube 1 has a three-layered tube wall 1a, that is, a three-layer tube. That is, the fender tube 1 includes an outermost layer 1c (protective layer 3), an intermediate layer 1b (foul repellent layer 2) and an innermost layer 1d (protective layer 4) in order from the outside.

  The wrinkle repellent layer 2 which is the intermediate layer 1b is made of, for example, a wrinkle repellent (specifically, a wrinkle repellent encapsulated in a microcapsule) together with a synthetic resin material such as vinyl chloride resin, polyethylene resin or nylon resin as a base. Kneaded and molded. The content rate of the moth repellent in this moth repellent layer 2 is 1-2 weight%, for example. But this content rate is not necessarily limited to this numerical value, and may be less than that or more.

  The outermost layer 1c (protective layer 3) is made of a synthetic resin such as vinyl chloride resin, polyethylene resin, or nylon resin, and has ultraviolet resistance. Specifically, the outermost layer 1c preferably contains 2 to 5% by weight of carbon, whereby the UV resistance of the synthetic resin material that is the material of the outermost layer 1c is improved.

  The innermost layer 1d (protective layer 4) is formed, for example, by applying an insect repellent material to the inner surface of the moth repellent layer 2 and curing the insect repellent material. This insect repellent material is a mixture of a synthetic resin material and an insect repellent, specifically, a binder resin, a volatile solvent, and an insect repellent (specifically, an insect repellent encapsulated in a microcapsule) And after application | coating, a volatile solvent volatilizes, and an insect repellent material will harden | cure and form a film. Examples of the insect repellent component include pyrethroid agents, organic phosphorus agents, carbamate agents, boron compounds, and fluorine compounds.

  Next, the function and effect of the fender 1 having the above configuration will be described. According to this hail tube 1, the hail repellent layer 2 is provided on the intermediate layer 1 b, and the outermost layer 1 c and the innermost layer 1 d are composed of the protective layers 3 and 4 that protect the hail repellent layer 2. This acupuncture repellent does not adhere to human hands, and it is possible to prevent irritation to humans by this acupuncture repellent. And since the innermost layer 1d contains an insect repellent, insects are unlikely to enter the fender 1. That is, according to this fungus tube 1, the repellent layer 2 is provided on the intermediate layer 1b, the outermost layer 1c and the innermost layer 1d are the protective layers 3 and 4, and the innermost layer 1d contains the insect repellent. Therefore, it is possible to prevent the moth repellent from adhering to the human hand, and it is difficult for insects to enter the protection tube 1, and the insects enter the building and the like through the protection tube 1. Can be prevented.

  Moreover, the outermost layer 1c has an ultraviolet resistant property. Thereby, even if the protection tube 1 is a case where it is arrange | positioned under the external light of the outdoors, the function as the protection tube 1 can be maintained long.
