Many of these active ingredients are liquid at room temperature and can be used as drugs as they are.
The active ingredient used in the present invention preferably has a vapor pressure of 1 × 10 ^{−5 to} 5 × 10 ⁻³ mmHg at 25 ° C. according to the Donovan method.
Here, the Donovan method is a method reported by Stephen F. Donovan in New method for controlling vapor pressure by the use of gas chromatography: Journal of Chromatography A. 749 (1996) 123-129.

  In addition, the purpose of evaporating the active ingredient of the drug may be other than the purpose of insect repellent, and for example, it can be used for the purpose of aroma. In this case, a drug containing an active ingredient having fragrance is used. Furthermore, it may be a drug containing active ingredients for fragrance and insect repellent, and may be for other purposes than insect repellent and aroma.

As a method of holding the drug in the holding unit 30, the active ingredient itself having volatility at room temperature may be used as it is, and the active ingredient may be held as it is, but the active ingredient may be an alcohol such as ethanol or isopropyl alcohol, acetone or the like. Ketones, polyethylene glycol, 1,3-butylene glycol, polyhydric alcohols such as ethylene glycol monobutyl ether, propylene glycol monomethyl ether, dipropylene glycol monomethyl ether, isopentane, light isoparaffin and light liquid isoparaffin (Idemitsu Petrochemicals: 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, ethyl acetate, isopropyl myristate, a A drug holding member 12 using a solution (that is, a drug having an active ingredient) obtained by appropriately diluting with one selected from esters such as diisopropyl dipinate and tributyl citrate, or a mixture thereof. Can be held by the holding portion 30.
In this case, the holding unit 30 may be immersed in such a liquid drug, or the liquid drug may be dropped and held in the holding unit 30.

Next, a method for using the drug diffusion device 1 will be described.
When the active ingredient of the drug is not diffused, for example, when it is sold or stored, the state shown in FIG. 1 is set. In other words, the annular frame portion 31 of the medicine holding member 12 is made small and is sandwiched between the disk members 20 a and 20 b of the main body member 11. In this state, the holding part 30 is folded to reduce the surface area, and the active ingredient of the medicine held in the holding part 30 of the medicine holding member 12 is difficult to diffuse.

  Then, in the place where the active ingredient of the drug is diffused, the disk members 20a and 20b of the main body member 11 are opened as shown in FIG. 2, and the drug holding member 12 is held as shown in FIG. The portion 30 is expanded so as to be planar. Then, as shown in FIG. 6, the disk members 20a and 20b of the main body member 11 are closed again, and the holding part 30 that is spread and flattened can be held between the disk members 20a and 20b.

  Since the holding part 30 is spread and becomes planar and has a large surface area, it is easy to diffuse the active ingredient of the drug. In addition, since a part of the planar holding part 30 can be sandwiched between the disk members 20a and 20b, the active ingredient of the medicine held in the holding part 30 can be further fanned like a fan. Can be diffused.

In order to further reduce the diffusion of the active ingredient of the drug in the state where the main body member 11 is closed, a close contact portion may be provided on the edge of the disk members 20a and 20b so that the edges of the disk members 20a and 20b are in close contact with each other. it can.
Specific examples of the contact portion include a fastener and a hook-and-loop fastener.

  In addition, a drug supply unit that can store a drug and supply the drug to the holding unit 30 can be provided inside the disc members 20 a and 20 b of the grip unit 20. And when a chemical | medical agent supply part is provided, the active ingredient of more chemical | medical agents can be diffused.

  Furthermore, a medicine holding member 51 as shown in FIGS. 7 and 8 can be used. The medicine holding member 51 is provided with a net-like protective portion 52, and the protective portion 52 is provided on both surfaces of the holding portion 30 as shown in FIG. The periphery of the protection part 52 is fixed by a frame fixing part 33. The other structure is the same as that of the medicine holding member 12.

Since the protection part 52 is provided in the medicine holding member 51, even when the user touches the medicine holding member 51, it is difficult to touch the holding part 30, and the liquid medicine held in the holding part 30 is directly touched. There is no.
Moreover, since the protection part 52 is net-like and can pass the active ingredient of the medicine, the active ingredient of the medicine held in the holding part 30 can be diffused. The size of the penetration part of the net of the protection part 52 can be used according to the application, but the penetration part is 1 mm square (1 mm ^{2 in} area) to 5 mm square (25 mm ^{2 in} area), and the user holds the holding part. 30 is difficult to touch, the diffusibility of the active ingredient of the drug is good, and such a range is desirable.
Furthermore, a sheet made of the same material as that of the protection unit 61 of the drug diffusion device 2 of the second embodiment to be described later can be used as the protection unit 52.

  Next, a drug diffusion device 2 according to a second embodiment of the present invention will be described. The drug diffusion device 2 is shown in FIG. 9 and includes a holding unit 30, a protection unit 61, and a frame member 60.

The holding unit 30 is the same as the drug diffusing device 1 of the first embodiment described above, is in a sheet shape, and holds a drug.
As a method for holding the medicine in the holding unit 30, the same method as in the first embodiment described above can be used.
That is, the active ingredient itself having volatility at room temperature may be used as it is, and the medicine may be used as a medicine, or a solution obtained by appropriately diluting the active ingredient (that is, a medicine having an active ingredient). It can be held by the holding portion 30 of the holding member 12. In addition, the chemical | medical agent used for dilution can use the thing similar to above-mentioned 1st Embodiment.
In this case, the holding unit 30 may be immersed in such a liquid drug, or the liquid drug may be dropped and held in the holding unit 30.

  Moreover, the protection part 61 is a sheet-like, and is an air permeable resin film which can let the active ingredient of the vaporized chemical | medical agent currently hold | maintained at the holding | maintenance part 30 pass. The protective part 61 may be made of a non-woven fabric that has excellent air permeability and little drug penetration. In addition, two protection parts 61 of the drug diffusion device 2 are used, and are provided so as to cover the surfaces on both sides of the holding part 30.

  The protection part 61 and the holding part 30 have substantially the same shape, are matched to the shape of the annular frame part 62 of the frame member 60 described later, and are arranged in the frame of the annular frame part 62.

  The frame member 60 is a molded product made of resin, and includes two members, a first frame member 60a and a second frame member 60b. The first frame member 60a and the second frame member 60b have the same shape. The first frame member 60a and the second frame member 60b can be combined and integrated with the holding unit 30 and the protection unit 61 interposed therebetween. The frame member 60 has an annular frame portion 62 and a grip portion 63.

  Any material can be used for the frame member 60, such as polypropylene, polyamide, polyethylene terephthalate, polystyrene, acrylonitrile-butadiene-styrene copolymer, polyoxymethylene, biodegradable resin, aluminum, titanium, iron, etc. Metal materials such as tin, tin, and other metal materials, paper, bamboo, 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. In addition, when a polyamide is used, it is preferable because the drug hardly permeates.

As shown in FIG. 9, the annular frame portion 62 is an annular frame, and the holding portion 30 and the protection portion 61 are arranged inside the frame, and the holding portion 30 and the protection portion 61 are attached to the frame member 60. It is fixed.
The grip part 63 is a rod-like part, and protrudes so as to extend outside the frame on the opposite side to the inside of the annular frame part 62. As shown in FIG. 9, the gripping portion 63 is provided on both the first frame member 60 a and the second frame member 60 b, but may be one.

Then, the first frame member 60a and the second frame member 60b of the frame member 60 are combined and integrated in a state where the holding unit 30 is sandwiched between the two protection units 61, whereby the drug diffusion device 2 is manufactured.
Then, as shown in FIG. 10, the frame member 60, the holding part 30, and the protection part 61 are integrally fixed. The integration method may be any method, but heat welding, adhesion with an adhesive, or the like can be used.
Further, the first frame member 60a and the second frame member 60b of the frame member 60 may be provided with engaging portions (not shown) so that they can be detachably integrated like a goldfish scooping frame. .

  Further, the protective part 61 can be insert-molded when the frame member 60 is molded, and the protective part 61 can be fixed when the frame member 60 is manufactured.

Next, a method for using the drug diffusion device 2 will be described.
The drug diffusion device 2 is moved to a location where the active ingredient of the drug is diffused. Then, the active ingredient of the medicine held in the holding unit 30 diffuses. Although the protection part 61 is provided on both sides of the holding part 30 so as to cover it, the active part of the vaporized medicine passes through the protection part 61, so that diffusion from the holding part 30 is possible. Moreover, the protection part 61 can make it difficult for a user to touch the holding part 30 directly, and safety is high.

In the drug diffusion device 3 shown in FIG. 11, the protection unit 61 is different from that of the drug diffusion device 2, and a net-like protection unit 61 b is used as the protection unit 61. In addition, the drug diffusing device 3 uses a frame member 60 and a protection unit 61 that are integrated.
Although the frame member 60 and the protection part 61 can be integrated by the above-described insert molding, the material of the frame member 60 and the protection part 61 is the same resin, and the frame member 60 and the protection part 61 are the same resin. It can also be a molded product.

As in the drug diffusing device 4 shown in FIG. 12, one of the two protective portions 61 can be a net-like protective portion 61b and the other can be a non-mesh permeable resin sheet protective portion 61a.
And the frame member 60 is made into one piece, and this frame member 60 and the net-like protection part 61b are integrated.
When a net-like part is used as the protective part 61, the size of the penetrating part of the net can be used according to the application, but the penetrating part is 1 mm square (1 mm ^{2 in} area) to 5 mm square (25 mm in area). ² ) It is desirable to make it difficult for the user to touch the holding part 30, and the diffusibility of the active ingredient of the drug is also good.

  The drug diffusion device 5 shown in FIG. 13 is different from the above-described drug diffusion device 2 in that the number of frame members 60 is one.

  And the structure of the frame member 60 of this invention integrated the 1st frame member 60a and the 2nd frame member 60b like FIGS. 9-11 and the chemical | medical agent diffusion apparatus 2,3,4 shown. The structure may be sufficient, and the structure which attached the protection part 61 and the holding | maintenance part 30 to the frame member 60 as a single member like FIG.12, FIG.13 and the chemical | medical agent diffusion apparatus 5 shown may be sufficient.

  Moreover, the chemical | medical agent diffusion apparatus 2a, 3a, 4a, 5a shown in FIGS. 14-17 is also employable. In the drug diffusion devices 2a, 3a, 4a, and 5a, the diffusion prevention unit 65 is disposed on the outer layer of the protection unit 61 that constitutes the drug diffusion devices 2, 3, 4, and 5 described above.

The diffusion preventing unit 65 can block the passage of the active ingredient of the vaporized medicine, and is easily attached.
The diffusion preventing unit 65 is attached at the time of distribution or sale, and is removed at the time of use. Therefore, if it is configured as the drug diffusion devices 2a, 3a, 4a, and 5a, it is possible to reduce the useless active ingredient of the drug that is diffused before use.

  In the drug diffusion devices 2a, 3a, 4a, and 5a described above, the annular frame portion 62 of the frame member 60 is single, and the protective portion 61 and the holding portion 30 are provided in one frame. However, as in the drug diffusion device 6 shown in FIGS. 18 and 19, a plurality of frame members 70 may be provided, and the protection unit 61 and the holding unit 30 may be provided on each of the frame members 70.

The drug diffusing device 6 has a plurality of frame members 70 and is provided with a shaft portion 71 and rotatably connected to form a fan shape. Accordingly, the drug diffusing device 6 is easily spread as shown in FIG. 18 when used, so that the active ingredient of the drug is easily diffused from the holding portion 30, and the frame member 70 overlaps as shown in FIG. 19 when not used. By folding in this way, it is possible to make it difficult for the active ingredient of the drug to diffuse.
Further, the diffusion preventing layer 72 can be provided on the outermost layer of the frame member 70 in the folded state.

In the drug diffusion devices 1, 2, 3, 4, 5, 6, 2a, 3a, 4a, and 5a described above, the active ingredient of the drug can be diffused from both sides of the holding unit 30.
