Description

[Detailed description of the invention] This invention is ideal for storage furniture, specifically Japanese dance furniture, wardrobes, chests of drawers, costume boxes (including moss boxes), water sheds, bookshelves, etc., which are ideal for insect-proofing. Regarding storage furniture.

Conventionally, as an insect repellent measure for the above-mentioned storage furniture, insect repellents such as paradichlorobenzene and camphor are generally applied to the storage furniture.
The effective period of these insect repellents is at most 3 to 4 months, and they must be replaced with new ones within a short period of time, making insect repellent management laborious.
In addition, the above insect repellents have a strong odor, which has the disadvantage of staining stored items such as clothing, and most of them are shaped into tablets, so there is a risk of them being accidentally ingested by children. .

As a result of intensive research, the inventors of the present invention found that conventionally, it was common knowledge that pyrethroid insecticides exert their medicinal effects by being evaporated by heating, or by bringing pests into contact with the insecticides. When impregnating wood with this, it gradually evaporates at room temperature, and it was discovered that the desired medicinal effect was sustained over a long period of time even at lower concentrations than paradichlorobenzene, camphor, etc., and the present invention was completed. did. That is, the present invention:
This storage furniture is characterized in that a pyrethroid insecticide that volatilizes and exhibits medicinal efficacy at room temperature is retained in at least the inner layer of one or all of the walls of the storage furniture.

In the present invention, a pyrethroid insecticide is used, which has a low vapor pressure, gradually evaporates at room temperature, and exhibits medicinal efficacy through a gas effect. Such an effect was first confirmed through research by the present inventor, and there has never been an example of a pyrethroid insecticide being used as an insect repellent using a gas effect.

The storage furniture of the present invention, which has been internally treated with such pyrethroid insecticides, maintains its insect repellent effect for a long period of time, for example, over 10 years, or virtually semi-permanently, unlike conventional products. There is no need for any complicated insect repellent work. In addition, since the above insecticides are retained by appropriate means such as impregnation on the inner wall surface of furniture, a large volatilization area is obtained, and even though they are slow-release, they are effective against burrs, carp moths, Japanese carp bugs, Japanese carp bugs, etc. It exhibits an excellent insect repellent effect against stored grain pests, and when sanitary pests such as cockroaches crawl on the chemically treated wall surface, it attaches to them and kills them. Furthermore, since the pyrethroid insecticide used in the present invention is substantially odorless, the odor of the agent does not permeate stored items such as clothing, and the insecticide is retained within the walls of furniture. Because of this, there is no risk of it being accidentally ingested by children, making it extremely safe.

In the present invention, storage furniture includes all furniture used for storing items, such as Japanese dance, wardrobe, chest of drawers, costume boxes (including moss boxes), water closets, and bookshelves. etc. can be exemplified.

The following are examples of pyrethroid insecticides that volatilize at room temperature and exhibit certain effects.

Γ 3-allyl-2-methylcyclopent-2-
En-4-one-1-yl chrysanthemate (generic name: allethrin) Γ N-(3,4,5,6-tetrahydrophthalimido)-methyl chrysanthemate (generic name: phthalthrin) Γ 5-benzyl-3 -furylmethyl chrysanthemate (generic name: resmethrin) Γ 5-propargyl-3-furylmethyl chrysanthemate (generic name: furamethrin) Γ 2-methyl-5-propargyl-3-furylmethyl chrysanthemate (generic name: Γ 3-Phenoxybenzyl d-cis/trans-chrysanthemate (generic name: Phenothrin) Γ 3-Phenoxybenzyl 2,2-dimethyl-3-(β,β-dichloro)vinylcyclo Propane carboxylate (generic name: permethrin) and their steric and optical isomers Γ An optical isomer of allethrin (trade name: Vinamine fluorte; manufactured by Sumitomo Chemical Co., Ltd.) Γ Stereo-optical isomers of allethrin (trade name: Exrin; (Manufactured by Sumitomo Chemical Co., Ltd.) Γ Stereo-optical isomer of allethrin (Product name: Bioallethrin; manufactured by Roussel. Euclaf) Γ Optical isomer of resmethrin (Product name: Chrylonfuorte; Manufactured by Sumitomo Chemical Co., Ltd.) The above examples Particularly preferred among the pyrethroid insecticides are allethrin, flamethrin, propulthrin, and their steric and optical isomers.

Next, an embodiment of the present invention will be described with reference to the drawings. A pyrethroid insecticide that can volatilize at room temperature and exert its medicinal effect is retained in at least the inner layer of the wall surface 2 in the storage furniture 1. In this specification, the wall surface 2 inside the storage furniture 1 refers to the inner wall surface of the main body,
If the furniture is equipped with furniture constituent members such as tray members, the term is used to include the wall surfaces existing inside the furniture.

FIG. 1 shows an example of storage furniture 1 and a wardrobe. As is clear from the partially enlarged sectional view of FIG. 2, the pyrethroid insecticide 3 is impregnated and held in the inner layer of the wall surface 2 of the main body, and gradually evaporates through the wall surface 2 to exert its medicinal effect. In FIG. 1, 1a is an extractor, and the insecticide may be retained on the wall surface portion of the extractor 1a existing in the furniture 1.

3 to 5 show an example in which the storage furniture 1 is a Japanese dancer. In this case, the pyrethroid insecticide is added to the inner wall of the body,
It is also held on the surface of the tray member 1b and/or the front, rear, left and right side plates of the tray member 1a, and the inner wall surface 2 of the bottom plate.

FIG. 6 shows an example where the storage furniture 1 is a moss box. Moss boxes are generally made of paper and have their inner surfaces treated with the above-mentioned chemicals.

Further, FIG. 7 shows a case where the storage furniture 1 is a water shed, and 2 in the figure shows a wall surface treated with chemicals.

The pyrethroid insecticide does not necessarily have to be applied to the entire surface of the wall 2, but may be applied only partially. The application may be not only to the inner layer but also to the entire layer. In the case of a Japanese chest of drawers, which is provided with furniture components such as trays, the insecticide may be applied only to the walls of these components.

The means for holding the pyrethroid insecticide on the wall surface 2 of the storage furniture 1 is not particularly limited, but for example, when the storage furniture is made of wood or cardboard, an impregnation method (normal pressure, reduced pressure, pressurization method), Coating methods, spraying methods, etc. can be applied. If it is made of wood, a hole may be made in the wood with a drill and the chemical solution may be injected into the hole. Such means may be applied at the raw material stage before manufacture, or at the product stage after manufacture. In addition, when the furniture is made of synthetic resin, the above-mentioned insecticide is mixed into the molding raw material in a state where it is supported on silica or the like, if necessary, at the stage of molding the product or its component parts.

Further, a carrier supporting the above-mentioned drug may be embedded in a synthetic resin.
