  The three frame-shaped members 13 are positioned so that the frame-shaped member 13 is sandwiched between the pair of plate-shaped members 11a and 11b. And in the state which the main body member 11 opened, the clearance gap is formed between plate-shaped member 11a, 11b, the frame-shaped member 13, and the frame-shaped members 13. In addition, the angle (gap angle) formed between the plate-like members 11a, 11b, the frame-like member 13, and the frame-like members 13 is substantially the same in the embodiment shown in FIG. Yes, the frame-like members 13 are arranged at equal intervals between the pair of plate-like members 11a and 11b.

  The material of the frame-shaped member 13 is, for example, plating on resin materials such as polyamide, polyethylene terephthalate, polystyrene, acrylonitrile-butadiene-styrene copolymer, metal materials such as aluminum, titanium, and iron, and metal materials such as tin and tin. Materials such as the above-mentioned materials, paper, and wood can be used. In addition, a laminate having layers of different materials can be used, and a layer having excellent gas barrier properties such as polyamide, polyethylene terephthalate, and aluminum can be provided on a part of this layer by coating or the like. Moreover, the same material as that used for the plate-like members 11a and 11b can be used.

  The arrangement of the frame-like member 13 is maintained by the positioning member 15. The positioning member 15 of this embodiment is a string-like member having flexibility. The positioning member 15 is fixed at a position away from the plate-like members 11 a and 11 b and the hinge portion 20 of the frame-like member 13. When the main body member 11 is opened, the positioning member 15 that is a string-like member is pulled, and the frame-shaped members 13 are maintained at regular intervals.

  The positioning member 15 of the drug diffusing device 1 uses a string-like member, but if it can be maintained at a predetermined interval between the frame-like members 13, other members such as springs are used. You can also.

  The drug holding member 12 is a flexible net-like member that holds a drug. And in the chemical | medical agent diffusion apparatus 1 of this embodiment, the chemical | medical agent holding member 12 has three sheets, and it fixes to each of the three frame-shaped members 13 1 each. The drug holding member 12 is fixed to the frame member 13 in a planar shape.

As the material for the drug holding member 12, a synthetic resin fiber, natural fiber, or the like made into a thread and knitted using the same, or a synthetic resin molded into a net shape is used.
As the types of fibers used for the drug holding member 12, synthetic fibers such as polyester and polyamide, semi-synthetic fibers such as acetate, and regenerated fibers such as rayon and cupra can be used. In addition, the basis weight when making a net using these fibers is usually 1 to 10,000 g per square meter.

A medicine is held on the medicine holding member 12. This drug has volatility at room temperature. Moreover, this chemical | medical agent has what has an insect repellent effect, for example. The “insecticidal effect” is a concept including both an “insecticidal effect” and an “insect repellent effect”.
The chemical | medical agent employ | adopted by this embodiment has normal temperature volatility, and specifically, the vapor pressure in 25 degreeC is 1.33 * 10 < ^-4 > Pa (1 * 10 < ^-6 > mmHg) or more.

Specific examples of active ingredients that have an insect repellent effect and evaporate at room temperature include the following.
1-ethynyl-2-methyl-2-pentenyl 3- (2-chloro-2-fluorovinyl) -2,2-dimethylcyclopropane-1-carboxylate, 2,3,5,6-tetrafluoro-4- Methylbenzyl 3- (2-methyl-1-propenyl) -2,2-dimethylcyclopropanecarboxylate, 2,3,5,6-tetrafluoro-4-methylbenzyl 3- (2-chloro-2-fluorovinyl ) -2,2-dimethylcyclopropanecarboxylate, 2,3,5,6-tetrafluoro-4-methylbenzyl 3- (1-propenyl) -2,2-dimethylcyclopropanecarboxylate, 1-ethynyl-2 -Methyl-2-pentenyl (1R) -3- (2-methyl-1-propenyl) -2,2-dimethylcyclopropanecarboxylate ( Generic name: Empentrin), 2,3,5,6-tetrafluorobenzyl (1R) -trans-3- (2,2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate (generic name: transfluthrin) ), 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl (1R) -trans-3- (1-propenyl (E / Z = about 8/1))-2,2-dimethylcyclopropanecarboxy 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl (1R) -trans-3- (2-methyl-1-propenyl) -2,2-dimethylcyclopropanecarboxylate, 2,3, 5,6-tetrafluoro-4-methylbenzyl (1R) -trans-3- (1-propenyl (E / Z = about 8/1))-2,2-dimethylcyclopropyl Pancarboxylate 1-ethynyl-2-methyl-2-pentenyl 3- (2-methyl-1-propenyl) -2,2-dimethylcyclopropanecarboxylate 1-ethynyl-2-methyl-2-pentenyl 3- (2 , 2-dichlorovinyl) -2,2-dimethylcyclopropanecarboxylate, pyrethroid compounds, 2,2-dichlorovinyl dimethyl phosphate, N, N-diethyl-m-toluamide, caran-3,4-diol.

  A drug having volatility at room temperature may be held in the drug holding member 12 as it is. However, the drug may be an alcohol such as ethanol or isopropyl alcohol, polyethylene glycol, 1,3-butylene glycol, ethylene glycol monobutyl ether, propylene glycol. Polyhydric alcohols such as monomethyl ether and dipropylene glycol monomethyl ether, isopentane, light isoparaffin and light liquid isoparaffin (Idemitsu Petrochemical: IP Solvent 1620, 2028, 2835 ExxonMobil: Isopar E, G, H, L, M), JIS No. 1 kerosene and No. 2 kerosene, hydrocarbon solvents such as alkylbenzene, esters such as ethyl acetate, isopropyl myristate, diisopropyl adipate, tributyl acetate citrate Either selected from among, or may be held by the drug holding member 12 using a solution obtained by diluting appropriate a mixture thereof.

  As a method of holding the drug on the drug holding member 12, a mesh may be used by using a thread or the like holding the drug, or the drug may be impregnated by immersing the drug in a net-like material. Moreover, the quantity of the chemical | medical agent hold | maintained at this time is 20 mg-500 g normally per square meter. That is, if the amount of the drug is excessively large, there is a problem that the drug hangs down, and if the amount of the drug is small, the effective period is shortened. Therefore, the amount of the drug held in the drug holding member 12 is appropriately 20 mg to 500 g per square meter. It is.

The total area of the drug holding member 12 is appropriately sized depending on the environmental conditions and the type of drug used, but is usually 50 to 2000 cm ² .
In the drug diffusion device 1 of the present embodiment, one drug holding member 12 is fixed to each frame-shaped member 13, but two or more nets are stacked on one frame-shaped member 13. A multiple structure may be adopted.

Next, a method for using the drug diffusion device 1 will be described.
After the drug diffusion device 1 is manufactured and before use, the main body member 11 is kept closed as shown in FIGS. When the main body member 11 is closed, the frame-like member 13 and the drug holding member 12 are disposed between the plate surface portions 24 of the plate-like members 11a and 11b, and the drug holding member 12 is a plate-like member. It is accommodated in the space 22 formed by the recesses 21 and 21 of 11a and 11b, and volatilization of the medicine of the medicine holding member 12 can be suppressed.

And the chemical | medical agent diffusion apparatus 1 is moved to the place which performs insect prevention, the latching by the latching member 16 is released, and as shown in FIG. 2, it is set as the main body member 11 in the open state.
When the main body member 11 is in an open state, the drug holding member 12 is exposed to the outside, and the volatilization of the drug becomes possible. Moreover, since the medicine holding member 12 is attached to the frame-like member 13, the net-like medicine holding member 12 can be reliably expanded.

  Since the chemical | medical agent holding member 12 is net shape, if ventilation, such as an electric fan and a cooler, or natural wind hits the chemical | medical agent diffusion apparatus 1, the said wind will pass the hole of a net | network. Therefore, not only the direction along the medicine holding member 12 but also the wind from any direction can be passed. Then, when the medicine hits the medicine holding member 12, the wind passes with almost no resistance, and the medicine can be diffused efficiently. Therefore, the medicine held on the medicine holding member 12 can be easily diffused.

  Further, the medicine holding member 12 is fixed substantially in a flat shape by a frame-like member 13, and the frame-like member 13 is arranged at equal intervals between the pair of plate-like members 11 a and 11 b by the positioning member 15. Therefore, the positions of the drug holding members 12 are separated from each other, and a large amount of drug can be efficiently diffused.

When the use is interrupted, the main body member 11 is closed, locked by the locking member 16, and again brought into the state shown in FIG. As a result, volatilization of the drug held on the drug holding member 12 can be suppressed. In this state, since the volatilization of the drug from the drug holding member 12 can be suppressed as described above, the drug diffusion device 1 of the present embodiment can be used only when insect protection is necessary.
Further, the net-like drug holding member 12 holding the drug is covered with the main body member 11 or the like when insect repellent is necessary, so that even when the drug holding member 12 is sticky, it is easy to carry and sell. .

Next, the drug diffusion device 2 according to the second embodiment will be described. As shown in FIG. 4, the drug diffusion device 2 is provided with a main body member 11, a drug holding member 62, and a frame-shaped member 13.
The structure of the drug diffusion device 2 other than the drug holding member 62 is the same as that of the drug diffusion device 1 of the first embodiment described above. In the description of the drug diffusion device 2, the drug of the first embodiment is used. The reference numerals used in the description of the spreading device 1 are used to omit the description.

  In the first drug diffusion device 1 described above, the drug holding member 12 is fixed to each frame-like member 13 in a planar shape. However, the drug holding member of the drug diffusion device 2 of the second embodiment is used. As shown in FIG. 4, 62 is provided outside the frame member 13 so as to cover the frame member 13. The shape of the drug holding member 62 is a shape like a semi-cylindrical surface when the main body member 11 of the drug diffusion device 2 is open. Also in the present embodiment, the frame-shaped member 13 and the drug holding member 62 are fixed, but this fixed position is a frame-like shape between the pair of plate-shaped members 11a and 11b with the main body member 11 opened. This is a position where the members 13 are arranged at equal intervals.

The appearance of the drug diffusing apparatus 2 with the body member 11 closed is the same as that of the drug diffusing apparatus 1 in the first embodiment shown in FIG. The internal structure of the drug diffusing apparatus 2 with the main body member 11 closed is shown in FIG.
When the main body member 11 of the drug diffusion device 2 is closed, the frame-shaped member 13 and the drug holding member 62 are disposed in the space 22 inside the main body member 11, and the drug holding member 62 is folded or curved. Therefore, it is located around the frame-shaped member 13.

  The method of using the drug diffusing device 2 is the same as the method of using the first embodiment (the drug diffusing device 1). When insect protection is not required, the drug holding member 62 is not exposed with the main body member 11 closed. Thus, when insect protection is required, the medicine holding member 62 is exposed with the main body member 11 opened, and the medicine is diffused.

  As still another modification, the drug diffusion device 3 shown in FIG. 6 can be used. The drug holding member 72 provided in the drug diffusion device 3 includes both the drug holding member 12 provided in the drug diffusion device 1 and the drug holding member 62 provided in the drug diffusion device 2. The drug diffusion device 3 can further hold a larger amount of drug and increase the drug diffusion amount. That is, since the area of the medicine holding member 72 to be used can be increased, more medicine can be held.

  As another modified example, a structure in which a drug supply unit 65 is provided in the vicinity of the hinge portion 20 and the drug supply unit 65 is brought into contact with the drug holding member 12 as in the drug diffusion device 4 shown in FIG. . Then, the medicine can be supplied to the medicine holding members 12, 62 and 72.

In the drug diffusion devices 1, 2, 3, and 4 described above, the main body member 11 can be closed and the space 22 for storing the drug holding members 12 and 62 is the plate surface portion 24 of the plate-like members 11a and 11b. Although the side surface portion 23 is used, other structures can be used if the space 22 can be formed by closing the main body member 11.
For example, the space 22 can be formed using a pair of plate-like members 11a and 11b that are provided with the recess 21 on one side and not provided with the recess 21 on the other side. Thus, the shape of the pair of plate-like members 11a and 11b may be different.
Further, like the drug diffusing member 5 shown in FIG. 8, the frame-like member 13 of the drug diffusing device 5 is closely attached in the thickness direction with the main body member 11 closed, and the plate surface portion 24 of the main body member 11 and the frame A space 22 for accommodating the medicine holding member 12 can be formed by the shaped member 13.

  In the drug diffusion devices 1, 2, 3, 4, and 5 described above, three frame members 13 are provided. However, the number of frame members 13 may be less than three (one or two), or may be four or more. If there are too many frame-like members 13, the gap between the frame-like members 13 is narrowed, so the number of the frame-like members 13 is preferably 10 or less.

  Further, the drug diffusing devices 1, 2, 3, 4, and 5 are provided with a locking member 16 that can maintain the closed state of the main body member 11, but the main body member 11 is biased in the closing direction. A spring or the like may be provided to maintain the closed state of the main body member 11. In this case, means (such as a hook) for maintaining the main body member 11 in an open state is usually provided.

In addition, an indicator may be provided so that the remaining amount of medicine can be known.
This indicator is installed at a position where it is exposed when not in use and not exposed when not in use, and the color of the surface changes when exposed for a certain period of time. The installation position includes the frame-like member 13 and the inside of the plate-like members 11a and 11b.
