Description

  The present invention relates to a fistula containing a repellent.

  Conventionally, the antifungal tube containing an antifungal agent such as capsaicin (a repellent) has been required to be handled with care because the antifungal agent irritate the mucous membranes of human eyes and nose. Then, the laminated fender tube which covered the inner layer containing a fungicide with the outer layer which does not contain a fungicide was considered (for example, refer to patent documents 1).

Japanese Patent No. 3223801

  However, in the conventional anti-rust tube, the outer layer that does not contain an anti-fungal agent (a repellent) is easily rubbed off, and the inner layer that contains the anti-fungal agent (a repellent) is easily exposed. There was also a risk that irritation to people would also be a problem.

  The present invention has been made to solve the above-mentioned conventional drawbacks, and the object of the present invention is to prevent irritation to humans and to enhance the antifouling effect. To provide a tube.

In order to achieve the object, the fender according to the present invention has the following configuration. That is,
The fistula tube according to the first aspect of the present invention is a fender tube having a plurality of layers in the tube wall, and the tube wall includes a repellent layer containing a repellent agent comprising capsaicins. . The wrinkle repellent layer has a first wrinkle repellent layer that is the outermost layer of the tube wall and a second wrinkle repellent layer that is inside the first wrinkle repellent layer. Here, the content of the capsaicin composed of the capsaicins in the first and second repellent layers is relatively small in the first repellent layer and the second repellent layer. The layer is large.

  According to this fender tube, the content of the repellent agent composed of capsaicin is smaller in the first repellent layer as the outermost layer than in the second repellent layer inside the first repellent layer. ing. For this reason, a comparatively small wrinkle can be avoided by the 1st wrinkle repellent layer which is the outermost layer. In addition, there is a possibility that the first moth repellent layer may be bitten by a large moth, but in this case, the second moth repellent layer having a relatively large content of the moth repellent composed of capsaicins is provided. Exposed and its second wrinkle repellent layer can repel large wrinkles.

Moreover, the fender tube according to the invention of claim 2 is a fender tube having a plurality of layers in the tube wall,
The said tube wall is provided with the moth repellent layer containing a moth repellent. The wrinkle repellent layer has a first wrinkle repellent layer that is the outermost layer of the tube wall and a second wrinkle repellent layer that is inside the first wrinkle repellent layer. Here, the first moth repellent layer contains a moth repellent excluding capsaicins, and the second moth repellent layer contains a moth repellent consisting of capsaicins.

By providing the 2 鼠 repellent layer, the 2nd repellent layer can be protected by the 1st repellent layer, and the human irritation caused by capsaicins can be suppressed, and the first repellent layer and the first repellent layer having different components can be suppressed. The anti-bacterial effect can be enhanced by the 2 repellent layer. In addition, in this way, the first wrinkle repellent layer covers the inner second wrinkle repellent layer so that the second wrinkle repellent layer is hardly exposed to the outside, and the medicinal effects of capsaicins in the second wrinkle repellent layer are Can be maintained for a long time.

It is sectional drawing of a fender tube of one embodiment of this invention.

  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 the fist tube 1 has a plurality of layers on a 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 tube wall 1a of the fender tube 1 includes a fist repellent layer 2 containing a fist repellent made of capsaicins. The wrinkle repellent layer 2 has a first wrinkle repellent layer 2a which is the outermost layer of the tube wall 1a, and a second wrinkle repellent layer 2b inside the first wrinkle repellent layer 2a. Accordingly, the content of the cocoon repellent composed of the capsaicins in the first moth repellent layer 2a and the second moth repellent layer 2b is relatively small in the first moth repellent layer 2a and the second moth repellent layer 2b. Has become large.

  Moreover, the tube wall 1a of the fender tube 1 includes an innermost layer on the inner side of the second repellent layer 2b. This innermost layer consists of a protective layer 3 that protects the second moth repellent layer 2b without containing a moth 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 fistula tube 1 is composed of a first wrinkle repellent layer 2a that is the outermost layer, a second wrinkle repellent layer 2b, and a protective layer 3 that is the innermost layer in order from the outside. The first moth repellent layer 2a and the second moth repellent layer 2b, which are the moth repellent layer 2, are, for example, vinyl chloride based on a moth repellent (specifically, a moth repellent encapsulated in a microcapsule). It is kneaded and molded together with a synthetic resin material such as resin, polyethylene resin or nylon resin.

  In addition, in the first wrinkle repellent layer 2a, which is the outermost layer, the content of the wrinkle repellent composed of capsaicins is preferably 0.1 to 0.5% by weight, for example. The first wrinkle repellent layer 2a has UV resistance. Specifically, the first wrinkle repellent layer 2a preferably contains 2 to 5% by weight of carbon, thereby improving the UV resistance of the synthetic resin material that is the material of the first wrinkle repellent layer 2a. On the other hand, in the second wrinkle repellent layer 2b, the content of the wrinkle repellent made of capsaicin is preferably, for example, 1 to 2% by weight.

  The protective layer 3 that is the innermost layer of the tube wall 1a contains an insect repellent. For example, the protective layer 3 is formed by coating an insect repellent material on the inner surface of the moth repellent layer 2 (that is, the inner surface of the second moth repellent layer 2b) and curing the repellant repellent material. is there. 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 the fender 1, the outermost first repellent layer 2 a contains a repellent made of capsaicin, as compared with the second repellent layer 2 b inside the first repellent layer 2 a. The rate is getting smaller. For this reason, relatively small wrinkles can be avoided by the first wrinkle repellent layer 2a which is the outermost layer. And there is a possibility that the first wrinkle repellent layer 2a may be bitten by a large wrinkle, but in this case, the second wrinkle repellent layer in which the content of the wrinkle repellent composed of capsaicin is relatively large 2b is exposed, and large wrinkles can be repelled by the second wrinkle repellent layer 2b. Here, the first wrinkle repellent layer 2a may be thin so that a large wrinkle can reach the second wrinkle repellent layer 2b with a single bite. Can be avoided.

  Thus, according to this fender 1, the outermost layer is provided with the first moth repellent layer 2a having a small content of capsaicin composed of capsaicin, and the content of the moth repellent composed of capsaicin is provided inside. By providing the large second wrinkle repellent layer 2b, the frequency with which the outermost layer (first wrinkle repellent layer 2a) is bitten by wrinkles and the inner layer (second wrinkle repellent layer 2b) is exposed decreases. As a whole, it is possible to suppress irritation to a person and to enhance the antifungal effect. Further, in this way, the first wrinkle repellent layer 2b covers the inner second wrinkle repellent layer 2b, so that the second wrinkle repellent layer 2b is hardly exposed to the outside, and the capsaicins in the second wrinkle repellent layer 2b The medicinal effects of can be maintained for a long time.

  Further, a protective layer 3 for protecting the second soot repellent layer 2b is provided on the inner side of the second soot repellent layer 2b, and the protective layer 3 is used as the innermost layer, so that the soot repellent is provided on the inner surface of the soot tube 1 Will not be exposed. For this reason, when a wiring material or a piping material is passed through the inside of the fender 1, it prevents the wrinkle repellent from adhering to the wiring material or the piping material, and also prevents the wrinkle repellent from adhering to human hands. be able to. In addition, in this way, the second wrinkle repellent layer 2b is not exposed to the inside by the protective layer 3, and the capsaicins in the second wrinkle repellent layer 2b are formed by the protective layer 3 and the first wrinkle repellent layer 2a. Can be maintained for a longer period of time.

  In addition, since the innermost layer contains an insect repellent, it is difficult for insects to enter the protection tube 1 and prevent the insects from entering the building or the like through the protection tube 1. Can do.

  In addition, the first wrinkle repellent layer 2a, which is the outermost layer, has UV resistance. Thereby, even if it is a case where the fender tube 1 is arrange | positioned under the external light of the outdoors, the function as the fender tube 1 can be maintained long.

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the fender tube 1 is formed of a corrugated tube, but the corrugated tube may be formed in a spiral shape in addition to the concave and convex portions constituting the wave being formed in a ring shape. Further, the fender tube 1 may be a smooth tube instead of a corrugated tube.

  Further, the wrinkle repellent layer 2 (the first wrinkle repellent layer 2a and the second wrinkle repellent layer 2b) contains a wrinkle repellent composed of capsaicins, but the first wrinkle repellent layer 2a which is the outermost layer of the tube wall 1a In addition, it contains a wrinkle repellent excluding capsaicins, and the second wrinkle repellent layer 2b inside the first wrinkle repellent layer 2a may contain a wrinkle repellent made of capsaicins. Here, the wrinkle repellent excluding capsaicins in the first wrinkle repellent layer 2a includes, for example, bitter components such as denatonium benzoate and cycloheximide, odor components such as terpenoids, and fragrances such as mint and mint. It is done. According to the fender 1, the outermost first repellent layer 2 a contains a repellent other than capsaicin, and the inner second repellent layer 2 b contains a repellent made of capsaicin. To do. For this reason, the 2nd eyelid repellent layer 2b containing the capsaicin which irritate | stimulates a person can be protected by the 1st eyelid repellent layer 2a which is the outermost layer. And the antifungal effect can be heightened by providing the layer from which the 1st habit repellent layer 2a and the 2nd habit repellent layer 2b differ as the wrinkle repellent layer 2. That is, by providing the first moth repellent layer 2a containing the moth repellent excluding capsaicins on the outermost layer and providing the second moth repellent layer 2b containing the moth repellent consisting of capsaicins on the inner side, The repellent layer 2b can be protected by the first repellent layer 2a to suppress irritation to humans by capsaicins, and the first repellent layer 2a and the second repellent layer 2b having different components can prevent The effect can be enhanced. Further, in this way, the first wrinkle repellent layer 2b covers the inner second wrinkle repellent layer 2b, so that the second wrinkle repellent layer 2b is hardly exposed to the outside, and the capsaicins in the second wrinkle repellent layer 2b The medicinal effects of can be maintained for a long time.

  Further, the first wrinkle repellent layer 2a and the second wrinkle repellent layer 2b have a wrinkle repellent (specifically, a wrinkle repellent encapsulated in a microcapsule) as a base such as vinyl chloride resin, polyethylene resin, nylon resin, etc. In particular, the first wrinkle repellent layer 2a may be formed by coating with a paint or the like. That is, the first wrinkle repellent layer 2a may be formed, for example, by coating a wrinkle repellent material (coating material) on the outer surface of the second wrinkle repellent layer 2b and curing the wrinkle repellent material. . If carbon is added to the soot repellent material, the UV resistance characteristics (that is, weather resistance) of the first soot repellent layer 2a and thus the soot tube 1 are improved.

  Further, the fender tube 1 has three layers of the tube wall 1a, but by omitting the protective layer 3, the fist tube 1 has two layers of a first repellent layer 2a and a second repellent layer 2b. The wrinkle repellent layer 2b may be the innermost layer. On the other hand, by providing another layer between the first heel repellent layer 2a and the second heel repellent layer 2b or between the second heel repellent layer 2b and the protective layer 3, the tube wall 1a May consist of four or more layers.

  Further, the first soot repellent layer 2a which is the outermost layer has an ultraviolet resistance, but may not have this ultraviolet resistance depending on the place where the fender tube 1 is disposed.

  Further, the protective layer 3 which is the innermost layer is formed by applying an insect repellent material containing an insect repellent, but an insect repellent (specifically, an insect repellent encapsulated in a microcapsule) is the base. It may be kneaded and molded together with a synthetic resin material (for example, vinyl chloride resin, polyethylene resin, nylon resin, etc.). In this way, the innermost layer contains the insect repellent, but does not need to contain this insect repellent. In addition, when the protective layer 3 which is the innermost layer does not contain an insect repellent, an insect repellent layer containing an insect repellent is intermittently provided on the inner surface of the protective layer 3 in the longitudinal direction of the fender tube 1. May be provided. Furthermore, when the fender tube 1 does not include the protective layer 3, the intermittent insect-proof layer may be provided on the inner surface of the second reed repellent layer 2b, for example, which is the innermost layer. In this way, when the insect repellent layer is provided intermittently on the inner surface of the innermost layer, even if an insect enters the fender tube 1, it is difficult for the insect to move in the tube.

  The tube wall 1a may be formed with a slit that allows the wiring / pipe material to be taken in and out through the tube wall 1a. The slit may be formed straight in the longitudinal direction with respect to the tube wall 1a, or may be formed in a spiral shape with respect to the tube wall 1a.
