Description

[Detailed explanation of the idea] [Purpose of invention]

[Industrial Application Field] The present invention relates to an insect-proof hanger for semi-permanently protecting clothing from insect damage. [Prior Art] (1) Background Feeding damage to clothing by larvae of bur moths, carp moths, Japanese carp moths, Japanese carp beetles, and Japanese carp beetles has been a major problem that has plagued housewives and the like since ancient times. One way to prevent food damage caused by these pests on clothes is to use insect-proof hangers that have insect-proof functions on the hangers themselves.
This method is considered to be an excellent method for clothes from the viewpoint of ease of handling and operability. Therefore, several ideas regarding insect-proof hangers have been proposed in the past, such as a method of drilling a hole in the hanger body and filling the hole with an insect repellent such as naphthalene, camphor tree, paradichlorobenzene, etc. There is a method of storing insect repellent in the hanger and providing volatilization holes in the hanger itself. (2) Problems with conventional techniques However, in any of these methods, it is difficult to suppress the volatilization rate of the insect repellent. Moreover, since there is a limit to the amount of chemicals that can be accommodated within the main body of the hanger, it is practically impossible to obtain an insect-proof hanger that is semi-permanently effective. However, according to the above method, there are various restrictions in terms of the material and design of the hanger.
It is also impossible to obtain a hanger that has a high-class feel. Therefore, in order to improve the above drawbacks, wooden materials,
In particular, insect-repellent hangers have been devised that are made of plywood and impregnated with insect repellent, but a new problem arises: when hanging clothes with long hems, such as coats, the insect-repellent effect is difficult to reach the hem. This problem has also been considered to be one of the drawbacks of insect-proof hangers. [Problems to be Solved by the Invention] Therefore, the purpose of the present invention is to provide a durable insect repellent hanger that can exhibit an insect repellent effect semi-permanently from the initial stage of use, and even to the hem of hanging clothing.

[Structure of the idea]

(1) Concept Therefore, as a result of intensive research aimed at solving the above problems, the inventor of the present invention selected a compound particularly selected from the following four types of low-volatile cyclopropane derivatives as an insect repellent for impregnation. It has been found that by drilling downward holes or grooves in the main body of the hanger containing the insect repellent, it is possible to satisfy both the requirements for persistence and dispersibility. a○: 1-ethynyl-2-methyl-2-pentenyl-2,2-dimethyl-3-(2'-methyl-1'-
propenyl)-cyclopropane-1-carboxylate b○: 1-ethynyl-2-methyl-2-pentenyl-2,2,3,3-tetramethylcyclopropane-1-carboxylate c○: 1-ethynyl-2 -Methyl-2-pentenyl-2,2-dimethyl-3-(2',2'-dichlorovinyl)-cyclopropane-1-carboxylate d○: 1-ethynyl-2-methyl-2-pentenyl-2, 2-dimethyl-3-(2'-methoxycarbonyl-1'-propenyl)-cyclopropane-
1-carboxylate. Incidentally, the above four types of cyclopropane derivatives themselves have poor volatility, so they cannot be expected to diffuse to an effective concentration, and for this reason, it is thought that it is difficult to expect a satisfactory insect repellent effect as an insect repellent for chests of drawers. It is a substance that exists. (2) Overview The present invention is based on the above knowledge, and its gist is to provide a hanger made from a material impregnated with at least one of the following cyclopropane insect repellents a○ to d○, which themselves have poor volatility. The insect-proof hanger is characterized in that the hanger is provided with holes and/or grooves that open downward in its main body. a○: 1-ethynyl-2-methyl-2-pentenyl-2,2-dimethyl-3-(2'-methyl-1'-
propenyl)-cyclopropane-1-carboxylate b○: 1-ethynyl-2-methyl-2-pentenyl-2,2,3,3-tetramethylcyclopropane-1-carboxylate c○: 1-ethynyl-2 -Methyl-2-pentenyl-2,2-dimethyl-3-(2',2'-diclobinyl)-cyclopropane-1-carboxylate d○: 1-ethynyl-2-methyl-2-pentenyl-2,2 -dimethyl-3-(2'-methoxycarbonyl-1'-propenyl)-cyclopropane-
1-carboxylate. The main points related to the structure of the invention will be explained below. (3) Insect repellents a○ to d○ The above insect repellents a○ to d○ used in the present invention include naphthalene, camphorax, paradichlorobenzene, pyrethrin, allethrin, resmethrin, flamethrin, safrole, insaflor, and other conventionally frequently used insect repellents. Compared to existing insect repellents, it exhibits sufficient insect repellent effects at extremely low gas concentrations, even though it has an extremely low vapor pressure at room temperature. Therefore, by impregnating a material such as wood with at least one of the present agents a○ to d○, it is possible to provide a hanger that exhibits a continuous insect repellent effect for at least 10 years. In addition, a synergist such as piperonyl butoxide, propyl isomer, piperonal dimethyl acetal, etc. may be used together with the above-mentioned drugs. (4) Hanger material There are no particular restrictions on the material of the hanger according to the present invention, and depending on the purpose, wood materials such as raw wood, plywood, particle board, chipboard, fiberboard, etc., acrylic resin, polyurethane resin, polystyrene resin, etc. Synthetic resins, ceramics, inorganic fiberboards, etc. can be used, but they need to be continuous porous materials in order to be impregnated with the drug. Further, as a means for impregnating these materials with the drugs a○ to d○, conventional means such as coating, dipping, pressure impregnation, reduced pressure impregnation, reduced pressure/pressure impregnation, etc. can be used as desired. (5) Holes or grooves The proposed hanger has downward holes and/or grooves in its main body as an essential component for the purpose of actively generating a downward flow of insect repellent vapor. The dimensions and shape of these holes and grooves can vary depending on the shape of the hanger, but generally the total area of the inner wall of these holes and grooves is 10% of the area before the holes were drilled. % to 50%. [Function] The hanger of the present invention has holes and/or grooves on the lower surface of its main body, so even though the insect repellent to be impregnated is hardly volatile, the gas of the insect repellent flows in a shower-like downward flow. Then, it continuously diffuses downward, and along with a small amount of insect repellent gas evaporating from other parts, it spreads to every corner of the clothing, especially to the sides of the hem. Therefore, even on long coats, it has a sufficient insect repellent effect not only initially but also for an extremely long period of time. In addition, with the hanger of the present invention, only grooves and holes are made on the underside of the main body, so
Free design is possible. [Example] Hereinafter, examples will be given to illustrate the mode of implementation of the idea.
The description is for illustrative purposes only and is not intended to limit the spirit of the invention. Embodiment 1 FIG. 1 is a partially cutaway front view showing an example of an insect-proof hanger according to the present invention, and FIG. 2 is a bottom view thereof. The hanger 1 of this example is made of a wood material, the entirety of which is impregnated with the above-mentioned insect repellent 2, and a linear groove 3 is cut into the lower surface 1a. In addition, the code|symbol 5 is a hanging hand, including each following drawing. Embodiment 2 FIG. 3 is a bottom view showing a modification of the hanger of the previous example. The hanger of this example differs from the previous example in that the groove 3 in the previous example is divided into two parallel grooves 3A and 3B. Embodiment 3 FIG. 4 is a cutaway front view showing yet another example of the invention, and FIG. 5 is a bottom view thereof. The hanger 1 of this example is also made of a wood material, and has a pair of left and right grooves 3C and 3D carved in its bottom surface. Embodiment 4 FIG. 6 is a cutaway front view showing yet another example of the invention, and FIG. 7 is a bottom view thereof. In the hanger 1 of this example, a plurality of round holes 4, 4, . . . are bored in its lower surface. As is clear from the above examples, the number of grooves is arbitrary and may be continuous, intermittent, or distributed left and right. Furthermore, instead of grooves, holes of any desired diameter, depth or number may be bored.
