BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gap between a water supply / drainage pipe in a kitchen sink / washroom and a floor through hole, a gap between a pipe for connecting an indoor unit and an outdoor unit of an air conditioner and a wall through hole,
Such as the gap between the water supply pipe for the sprinkler and the ceiling through hole,
The present invention mainly relates to a closing tool for closing a gap between an interior material and a pipe passing through the interior material.

[0002]

2. Description of the Related Art Cockroaches, chatterworms, tiny beetles, mites, mosquitoes, spots, etc. not only cause discomfort to humans but also cause food damage, become a vector of pathogenic bacteria and molds, and are hygienic problems. Bring In order to prevent the damage caused by these harmful insects, it is common practice to spray the insecticide directly onto the harmful insects or apply the insect repellent to the wall of the room or the surface of furniture to exterminate the insects.

[0003]

However, insecticides have a problem in terms of safety to the human body, and it is difficult to apply the insect repellent to all places effective for controlling pests.

The most reliable means of preventing damage from pests is
It is to prevent pests from entering the room. However, in order to install pipes for indoor and outdoor such as water supply and drainage pipes, floors, walls,
Since the through hole is formed in the interior material such as the ceiling, the pests enter through the gap between the through hole and the pipe. Then, conventionally, in order to prevent the invasion of harmful insects through the gap, a laborious construction means for sealing the gap is adopted.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide means for reliably preventing invasion of harmful insects by a simple construction method. The feature of the obturator according to the present invention is to close a gap between an interior material such as a floor, a wall, a ceiling and a pipe penetrating the interior material, and a gap cover around a pipe mounting portion. The pest repellent component is included in the part.

The gap cover may be made of a synthetic resin containing a pest repellent component, or a woven or non-woven fabric impregnated with the pest repellent component.

Further, the pest repellent component may be applied to the surface of the gap cover around the pipe mounting part facing the outdoor side, or a woven or non-woven fabric impregnated with the pest repellent component may be provided. You can also

The gap cover portion around the pipe mounting portion may be formed in a tapered shape.

By the way, the pest repellent component in the present invention (hereinafter referred to as "repellent component") may be any substance as long as the medicinal component is present to the extent that it exerts a repellent effect on the pest, and even if it has an insecticidal effect. It does not have to be provided. Of course, it does not prevent the repellent component from having an insecticidal effect, but those with a high insecticidal effect and those with a fast-acting effect not only have anxiety in terms of contact toxicity to the human body, but also that the pest carcasses remain indoors. There is also a hygiene problem.
Therefore, considering only the pest repellent property, it is not always required that the repellent component has a strong insecticidal power.

[0010]

In the obturator according to the present invention, the repellent component is present in the portion that closes the gap between the pipe and the through hole of the interior material, that is, in the gap cover portion around the pipe mounting portion. It tries to avoid contact with the repellent component and repels approaching the gap. Therefore, unlike the conventional case, it is not necessary to take time and seal the gap, and the invasion of harmful insects can be reliably prevented only by the simple work of mounting the obturator on the pipe.

The repellent component of the present invention need only have a medicinal component to such an extent that it exerts a repellent effect on pests, and since it may have a weak insecticidal power, it is excellent in safety for humans and at the same time, it is a corpse of pests. There is no problem in terms of hygiene as it does not remain inside the room.

When the gap cover around the pipe mounting portion of the obturator is formed of synthetic resin mixed with the repellent component, the repellent component is eluted from the inside and gradually diffused into the air ( Since it has a sustained release property, the insect repellent effect continues for a long time.

On the other hand, when applying a repellent component to the surface of the gap cover around the pipe mounting part or disposing a woven or non-woven fabric impregnated with the repellent component, the amount of the repellent component used should be reduced. Therefore, there is an advantage that the material cost can be reduced.

EXAMPLES The obturator according to the present invention can have various embodiments, and some examples thereof will be described below. [First Embodiment] As shown in FIG. 1, the obturator 1 according to the present embodiment has a pipe mounting portion 3 formed in a substantially central region of a base plate portion 2 formed in a flat plate shape or a sheet shape. 3 A repellent component is mixed in the gap cover 4 around, or
At least the surface facing the outdoor side is coated with the repellent component.

The planar shape of the obturator 1 is not particularly limited, and the most suitable one can be selected according to the use situation. For example, the disk-shaped one is illustrated in FIG. 1, but this is shown in FIG.
It can be a square in (A), a rectangle in (B) in the figure, or a regular hexagon as in (C) in the figure.

Regarding the position where the pipe mounting portion 3 is formed,
It is not essential that the central area of the substrate portion 2 is
Depending on the construction situation, it may be more convenient to form the pipe mounting portion 3 and the gap cover portion 4 at eccentric positions as shown in FIG.

Further, in this embodiment, the substrate portion 2 and the gap cover portion 4 are formed as separate members, but this is because the substrate portion 2 is formed by a member having rigidity such as hard vinyl chloride resin. This is to ensure the formability and to form the gap cover portion 4 with soft vinyl chloride resin, woven cloth, non-woven cloth or the like so as to have flexibility and flexibility. In this case, the substrate portion 2 and the gap cover portion 4 may be simultaneously molded and integrated, and as shown in FIG. 4, those separately manufactured may be bonded later by using an adhesive, a high frequency wave or the like. Does not hinder. Of course, as shown in FIG. 5, the substrate 2 and the gap cover 4 may be made of the same member.

As a material of the obturator 1, synthetic resin such as vinyl chloride or urethane is generally used, but in addition to this, a fibrous material such as rubber, metal, woven or non-woven fabric, or surface treatment may be used. It is also conceivable to use coated paper.

The pipe mounting portion 3 is for inserting a pipe, and this may be a simple opening.
As shown in FIG.
Is preferably provided to form the pipe mounting portion 3.

The repellent component blended or applied to the gap cover portion 4 has both drug efficacy and safety, that is, if the repellent effect is certain, the LD ₅₀ value (half the lethal dose) is as large as possible. Is desirable. Pyrethroids such as pyrethrins and synthetic pyrethrins (phthalthrin, allethrin, permethrin, phenothrin, cyphenothrin, etofenprox, bifenthrin, deltamethrin, cyfluthrin, cypermethrin, alpha-cypa are suitable for such conditions. -Methrin, cyhalothrin, flucisrinate, fluvalinate, fenvalerate, etc.), and natural essential oils (hinoki oil, cedar oil, hiba oil, etc.) having pest repellent action, and synergists that enhance the activity of repellent components. (Cinethrin, octachlorodipropyl ether, etc.) can also be added. Other repellent components include diethyltoluamide, menthol, 2,
3,4,5-bis (Δ ₂ butylene) tetrahydrofurfural, dinormalpropyl isocinchomeronate and the like can also be used, and the optimum one is selected according to the application. Further, it does not prevent the use of two or more kinds of drugs in combination.

The amount of the repellent component to be used is set in consideration of the type of the target pest and the type of drug to be used so that the repellent effect can be surely exhibited at a concentration as low as possible. That is, the pest repellent component may be present at a concentration of at least a threshold value that causes a repellent reaction with respect to the pest. Taking ciphenothrin or permethrin, which is one of the synthetic pyrethroids, as an example, the compounding amount of the active ingredient to the synthetic resin is 0.4 to 5.0%, or the application amount of the active ingredient per unit area is 0.1 to 2%. If it is adjusted to be 0.0 g / m ² or the KT ₅₀ value (the time required for half to knock down) for black crocodile to be 10 to 40 minutes, it is possible to avoid the insecticidal power with certainty. It can exert an effect and can have low toxicity.

Some drugs have the same repellent effect and have extremely low toxicity to the human body. With such drugs, the dose is more than the above without sacrificing the safety to the human body. It is also possible to further increase the repellent effect. For example, phenothrin can be used in an amount of 1.5 to 4.5 g / m ² applied to the substrate.

It is preferable from the economical point of view that the repellent component is compounded or applied only to the gap cover portion 4, but it is also prohibited to compound or apply it to the entire obturator 1 for manufacturing or other reasons. Absent.

The obturator 1 is for obstructing a gap between a drainage pipe P of a kitchen sink and a through hole 30 formed in the floor 20 for penetrating the same, as shown in FIG. 6 (A). is there. The attachment procedure of the obturator 1 is such that the drainage pipe P is inserted into the pipe mounting portion 3 in advance, and after the piping work is performed in this state, the base plate portion 2 is fixed to the floor 20 with an adhesive or the like to drain water. The gap between the pipe P and the through hole 30 is closed.
