Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, the demand for insecticides and repellents for pest control against sanitary pests such as cockroaches has been growing slowly. Countermeasures against nuisance pests such as mayflies and stink bugs are also recognized as targets for extermination. Many proposals for pest control have been made so far, and cockroaches mainly occupy the targets for extermination. Many extermination methods mainly involve scientific countermeasures (push type, etc.) for killing insects or preventing indoor intrusion when encountering the target insects and capturing them after indoor intrusion (treatment after killing insects). However, for those who dislike insects, encountering the target and the treatment after extermination are accompanied by mental pain. To reduce the mental burden, first preventing indoor intrusion becomes the first countermeasure. In the indoor intrusion countermeasure market, there is the use of insect repellents by scientific methods such as spray type. In recent years, there has been an increase in those with excellent repellent and insecticidal effects that have an intrusion prevention effect with a single push (such as push type), but due to the circumstances of the user, the use of spray and fumigation types is not possible, and the uneasiness about the sustainability of the effect due to air exchange, etc. cannot be eliminated.

[0005] The present invention has been made in consideration of such circumstances, and aims at a through-hole decorative cover that can prevent the intrusion of unpleasant pests.

Mode for Carrying Out the Invention

[0009] The through-hole decorative cover of the present invention has a seal portion that closes the gap between the pipe and the shielding object in the through-hole. The shielding structure of the present invention includes a shielding object having a through-hole, a pipe located in the through-hole, and a through-hole decorative cover having a seal portion that closes the gap between the shielding object and the pipe. Hereinafter, the present invention will be described with reference to embodiments. In this document, the "shielding object" is a part constituting a building, and examples include walls, floors, ceilings, doors, and the like.

[0010] (First Embodiment) The shielding structure according to the first embodiment of the present invention will be described. FIG. 1 is a perspective view showing the construction process of the through-hole decorative cover, and is a perspective view of the outer wall seen from the outside.

[0011] As shown in FIG. 1(a), for an outer wall W having a through-hole 10a, a pipe 20a is inserted into the through-hole 10a. In this state, a gap 12a is formed between the outer peripheral surface of the pipe 20a and the outer wall W within the through-hole 10a.

[0012] Next, in the gap 12a, putty is applied to the periphery of the pipe 20a and the putty is adhered to the outer wall W to close the gap 12a. In this way, a seal portion 30a is formed by the putty that closes the gap 12a from the outside of the outer wall W, and a shielding structure 1a is obtained (FIG. 1(b)). In this embodiment, the through-hole decorative cover is composed only of the seal portion 30a. That is, the shielding structure 1a of the present embodiment includes an outer wall (shielding object) W having a through hole 10a, a pipe 20a located in the through hole 10a, and a through hole decorative cover composed of a seal portion 30a that closes the gap 12a between the shielding object W and the pipe 20a.

[0013] Part or all of the seal portion 30a may be located within the through hole 10a, or all of it may be located outside the through hole 10a. The seal portion 30a only needs to close the gap 12a when viewed from the outer surface.

[0014] The paste for forming the seal portion 30a is preferably in a clay-like state. By using a clay-like paste, it is possible to easily adhere to the outer surface of the non-smooth outer wall W, the inside of the through hole 10a, or the outer surface of the pipe 20a to form the seal portion 30a. In addition, by using a clay-like paste, an appropriate amount of paste can be easily cut out, so that the construction work can be simplified.

[0015] The paste for forming the seal portion 30a may be a non-drying paste or a curable paste. However, from the viewpoint of construction simplicity, the paste for forming the seal portion 30a is preferably a non-drying paste. If it is a non-drying paste, an appropriate amount of paste can be easily cut out, and construction according to the shape of the gap is easy.

[0016] As the paste for forming the seal portion 30a, an elastic paste is preferably used. By forming the seal portion 30a with an elastic paste, construction on a curved surface can be facilitated. In addition, by forming the seal portion 30a with an elastic paste, the seal portion 30a can be easily removed during re-construction.

[0017] The paste for forming the seal portion 30a contains a paste base material and a repellent for unpleasant pests. Since the paste for forming the seal portion 30a contains a repellent for unpleasant pests, even if a gap is generated between the seal portion 30a and the outer wall W or the pipe 20a, it is possible to prevent unpleasant pests from entering the gap between the seal portion 30a and the outer wall W or the pipe 20a and the cracks generated in the seal portion 30a.

[0018] The objects to be repelled are so-called unpleasant pests, such as mayflies and stink bugs.

[0019] Examples of the unpleasant pest repellent include pyrethroid repellents. Examples of the pyrethroid repellents include permethrin, pyrethrin, allethrin, phthalthrin, resmethrin, flumethrin, phenothrin, empenthrin, prallethrin, imiprothrin, transfluthrin, silafluofen, etc. Among them, permethrin is preferable as the unpleasant pest repellent.

[0020] The content of the unpleasant pest repellent in the seal part 30a can be selected as an amount effective for repelling the unpleasant pests in consideration of the type of the unpleasant pests to be repelled and the type of the unpleasant pest repellent.

[0021] As the putty base material, any material that has been conventionally used as a hole-filling putty may be used, and examples thereof include silicone-based putty, polyester-based putty, and polyolefin-based putty. Among them, clay-like polyolefin-based putty is preferable from the viewpoint of workability.

[0022] The outer wall W is not particularly limited and may be any of siding, tiles, bricks, plaster, concrete, gypsum, plastic, etc.

[0023] The pipe 20a is not particularly limited, and examples thereof include an air conditioner drain pipe, a ventilation pipe, an electric wire, etc. Examples of the material of the pipe 20a include resins such as polyolefin (polyethylene, polypropylene, etc.), polyvinyl chloride, and metals.

[0024] The size of the through hole 10a is appropriately determined according to the outer diameter of the pipe 20a.

[0025] According to the through hole decorative cover of the present embodiment, since it has a seal part containing an unpleasant pest repellent, it is possible to prevent unpleasant pests from approaching the through hole by closing the gap in the through hole at the seal part. In addition, according to the through-hole decorative cover of the present embodiment, since the sealing portion is formed of a clay-like putty, it can be easily adhered to the uneven outer wall, inside the through-hole, or the outer surface of the pipe to form the sealing portion. The shielding structure of the present embodiment includes a shielding object having a through-hole, a pipe located in the through-hole, and a through-hole decorative cover including a sealing portion that closes a gap between the shielding object and the pipe. Since the sealing portion has an unpleasant pest repellent, even if a gap is formed between the sealing portion and the pipe or the shielding object, or a crack occurs in the sealing portion, it is possible to prevent unpleasant pests from entering the through-hole.

[0026] (Second Embodiment) The shielding structure according to the second embodiment of the present invention will be described. Hereinafter, mainly the configuration different from the first embodiment will be described. FIG. 2 is a perspective view showing a construction process of the through-hole decorative cover, and is a perspective view of the floor seen from the interior of the room.

[0027] As shown in FIG. 2(a), a pipe 20b is inserted through a through-hole 10b in a floor F having the through-hole 10b. In this state, a gap 12b is formed between the outer peripheral surface outside the pipe 20b and the floor F within the through-hole 10b.

[0028] Next, in the gap 12b, putty is applied around the periphery of the pipe 20b and the putty is adhered to the floor F to close the gap 12b. In this way, a sealing portion 30b is formed of the putty that closes the gap 12b from the upper surface of the floor F, and a shielding structure 1b is obtained (FIG. 2(b)). In the present embodiment, the through-hole decorative cover is composed only of the sealing portion 30b. That is, the shielding structure 1b of the present embodiment includes a floor (shielding object) F having a through-hole 10b, a pipe 20b located in the through-hole 10b, and a through-hole decorative cover including a sealing portion 30b that closes a gap 12b between the shielding object F and the pipe 20b.

[0029] Part or all of the sealing portion 30b may be located within the through-hole 10b, or all of it may be located outside the through-hole 10b. The sealing portion 30b only needs to close the gap 12b in the state seen from the interior of the room.

[0030] The paste for forming the seal part 30b is the same as the paste for forming the seal part 30a.

[0031] Examples of the pipe 20b include drain pipes for plumbing such as sinks and electric wires.

[0032] Examples of the material of the floor covering constituting the floor F include wood, concrete, tiles, and the like.

[0033] The size of the through hole 10b is appropriately determined according to the outer diameter of the pipe 20b.

[0034] (Other embodiments) In the first and second embodiments, the through-hole decorative cover is constituted only by the seal part, but the present invention is not limited to this, and the through-hole decorative cover may have members other than the seal part. For example, it may have a molded body that further covers the seal part.

[0035] In the first and second embodiments, the seal part is formed of paste, but the present invention is not limited to this. The seal part may be a molded body of a rigid resin. The seal part may be, for example, an injection molded product having a shape covering a gap with a composition of a thermoplastic resin (for example, polyolefin, polyvinyl chloride, etc.) containing an unpleasant pest repellent.

[0036] In the first embodiment, the seal part is provided on the outer surface of the outer wall, but the present invention is not limited to this. The seal part may be provided on the indoor side. However, when avoiding the volatilization of the unpleasant pest repellent into the room, the seal part is preferably provided on the outer surface (outdoor) of the outer wall.

[0037] In the first embodiment, the outer wall is used as a shielding object, but the present invention is not limited to this, and the shielding object may be an indoor wall. However, from the viewpoint of preventing the invasion of unpleasant pests, the wall as a shielding object is preferably the outer wall.

[0038] In the second embodiment, the sealing portion is provided on the upper surface of the floor (indoor side). However, the present invention is not limited to this, and the sealing portion may be provided on the lower surface of the floor.
