Thereby, the medicine held by the medicine holding portion 1 can be diffused toward the outside of the housing portion 2 by the vent hole 211. In this way, when the drug holding unit 1 is sealed in the accommodating unit 2, and the state in which the drug is stored or displayed in the store is not used, the activated carbon contained in the heat generating component 31 that is not adsorbed on the heat generating unit 3 is adsorbed. Since the material or the package 32 is used, it is not necessary to reduce the effect of controlling pests, or to maintain an excessive amount of the above-mentioned medicine in the drug holder 1 in order to exhibit a sufficient control effect. In addition, since the drug holding portion 1 is sealed in the accommodating portion 2, the drug holding portion 1 cannot be taken out from the outside. Therefore, it is possible to prevent the baby or the child from dropping the medicine holding portion 1 into the mouth. Further, in the first embodiment, the vent hole 211 of the first member 21 is shown by a long hole. However, as long as the medicine can be diffused toward the outside of the accommodating portion 2, in other embodiments, the shape of the vent hole can be made. It may be formed into a circular shape, a rectangular shape, or the like, and the first member 21 may be formed in a mesh shape formed by a plurality of fibers, or may be used as the first member 21 The material of the hole that allows the penetration of the aforementioned agent is not provided.

Further, a cover portion 23 covering the vent hole 211 is provided on the first member 21 of the accommodating portion 2, which is a member that closes the vent hole 211 when not in use. The back surface of the lid portion 23, that is, the surface abutting on the first member 21 is provided with an illustrated backing layer, and the peeling of the lid portion 23 from the first member 21 as shown in Fig. 3 can be made as described above. The medicament is discharged from the vent 211. By adhering the lid portion 23 to the first member 21, the vent hole 211 is covered, and the drug can be prevented from diffusing from the accommodating portion 2 to the outside. Therefore, when the present invention is not used, since the vent hole 211 is closed by the lid portion 23, it is possible to prevent the medicine from being unnecessarily volatilized from the medicine holding portion 1 even when stored at a normal temperature. Further, the lid portion 23 can be completely peeled off from the first member 21, and the entire vent hole 211 can be opened to communicate with the inside and outside of the accommodating portion 2; or the vent hole 211 can be peeled off from the accommodating portion 2 by half. Half of the degree is equally open. Thus, the amount of the medicine discharged from the accommodating portion 2 can be controlled according to the degree of opening and closing of the lid portion 23. Further, in the present embodiment, the lid portion 23 is represented by one sheet-like member, and in other embodiments, a plurality of lid portions 23 may be provided as long as the vent hole 211 can be covered.

Further, in the second embodiment, as shown in FIG. 4, a plurality of vent holes 211 penetrating the inside and outside of the accommodating portion 2 are formed in the vicinity of the outer peripheral portion of the second member 22 fixed to one side of the heat generating portion 3. By fixing the heat generating portion 3 or the like which is slightly smaller than the accommodating portion 2 to the accommodating portion 2, the medicine is diffused to the outside toward the heat generating portion 3 via the vent hole 211 at the time of use. Further, the second member 22 of the housing portion 2 is provided with a cover portion 23 that covers at least the vent hole 211, such as a rectangular corner ring shape, when it is not in use. The member that closes the vent 211. Further, in the lid portion 23, four rectangular members which are arranged on each side of the outer circumference of the second member 22 and which cover a plurality of vent holes 211 may be provided. The other configuration or effect of the lid portion 23 is the same as that of the first embodiment. Further, in another embodiment, the vent hole 211 may be formed in the first member 21 as in the first embodiment, and the vent hole 211 may be inserted in the second member 22 as in the second embodiment. Department 2.

In addition, in the first embodiment and the second embodiment, although not shown, in order to prevent heat generation of the heat generating portion 3 due to oxidation, it is necessary to seal the bag or the packaging container such as a box. In addition, the packaging container such as a bag or a box can be sealed at the time of opening, and the use of the heating and evapotranspiration pest control device can be temporarily interrupted, and the fixing portion such as a zipper or the like can be provided or used. The material of a part of the material can be heat-sealed and sealed. At this time, the material of the packaging container such as a bag or a case is preferably made of, for example, polyester, polypropylene, polyvinyl alcohol, ethylene vinyl copolymer, or polyvinylidene chloride in order to prevent penetration of oxygen or the like. A resin film such as ethylene or polyacrylonitrile, a plastic film coated with the resin, a metal foil made of a metal such as aluminum, or a film on which the metal is vapor-deposited, and more preferably a first portion constituting the housing portion 2 to be described later. The members 21 and the second member 22 and the lid portion 23 are made of the same material.

Further, in the third embodiment, as shown in FIG. 5, the first member 21 on the side opposite to the second member 22 fixed to one side of the heat generating portion 3 penetrates the inside and outside of the housing portion 2 The circular shape is provided with a plurality of vent holes 211. Unlike the first embodiment, the first configuration of the housing portion 2 The cover portion 23 covering the vent hole 211 is not provided in the member 21. Therefore, similarly to the heating-evaporable pest repellent of the first embodiment or the second embodiment, in addition to the constituent members shown in Fig. 5, it is necessary to seal such bags or boxes, etc., at the time of commercial sale. Packaging container. At this time, in order to prevent the medicine from scattering from the accommodating portion 2, it is preferable that the first member 21 of the accommodating portion 2 is in close contact with the inside of the packaging container to block the vent hole 211. Therefore, the material of the packaging container according to the third embodiment is preferably the same as the material of the first member 21, the second member 22, and the lid portion 23 constituting the housing portion 2 which will be described later. By forming the configuration in which the lid portion 23 is unnecessary, the above-described medicine can be prevented, and in particular, the active ingredient can be transferred to the heat generating portion 3, and the manufacturing step can be shortened and the pressure can be lowered. The cost of manufacturing is required, and further has a remarkable effect that it can be used immediately by the operation of opening the packaging container only once. Further, although not shown, the housing portion 2 and the heat generating portion 3 are fixed by the fixing portion 4 as in the first embodiment.

Moreover, the material of the first member 21 and the second member 22 and the cover portion 23 constituting the accommodating portion 2 is preferably nylon, ethylene such as polyethylene terephthalate, nylon 6 or nylon 6,6. a vinyl alcohol copolymer, a thermoplastic resin such as polyethylene, polypropylene, polyvinylidene chloride coated biaxially oriented polypropylene, or linear low-density polyethylene, or laminated with aluminum, copper, etc., having good thermal conductivity. A film made of a thermoplastic resin of a thin metal member, a metal film having good thermal conductivity such as aluminum or copper, more preferably polyethylene terephthalate, nylon or ethylene. One type or two or more types of vinyl alcohol copolymer. When the materials of the first member 21, the second member 22, and the lid portion 23 constituting the accommodating portion 2 are made of these materials, the medicine holding portion 1 is swayed. In particular, the active agent contained therein is not easily adsorbed to the accommodating portion 2 and the lid portion 23, and the drug can be efficiently discharged to the outside of the accommodating portion 2.

When the various types of materials are used as the accommodating portion 2 and the mesh-shaped drug holding portion 1 shown in Fig. 3 or the like is sealed, the ease of transfer of the active ingredient contained in the drug to the accommodating portion 2 is confirmed. In other words, first, 5 mg of mexene as an active ingredient is impregnated into the drug holding portion 1 with a solution diluted to 50 μL with isopropyl alcohol, and sealed in a container 2 made of various materials, and allowed to stand at 40 ° C. After the week, the drug holding portion 1 and the accommodating portion 2 were each extracted with 50 mL of methanol at a temperature of 25 ° C for 12 hours. Then, the extracted methanol solution was used as a mobile phase by using an aqueous methanol solution (methanol: water = 9:1) and equipped with an ODS column (manufactured by Shinwa Chemical Co., Ltd., STR ODS-II length 150 mm, inner diameter 6.0 mm) A liquid chromatograph (manufactured by Shimadzu Corporation, LC-2010 AHT) was used to quantify the Metlin. The quantification was carried out by an internal standard method using dihexyl phthalate as an internal standard substance. Thereafter, the residual ratio of the melixine in the drug holding portion 1 and the transfer rate of the melixine to the accommodating portion 2 were calculated from the results of the quantitative calculation. The arithmetic mean obtained by performing three analyses for each result is shown in Table 1.

As can be seen from Table 1, in nylon 6 with ethylene. In the accommodating portion 2 composed of a composite material composed of a vinyl alcohol copolymer and polyethylene terephthalate, since the melixine is not transferred to the accommodating portion 2 and remains in the drug holding portion 1, it is long-lasting even if it is not used. In the storage, the drug holding unit 1 can also hold a sufficient amount of the active ingredient of the aforementioned drug.

Further, the second member 22 may be made of a metal member such as aluminum or copper instead of the resin component. By forming the second member 22 as a metal member, the heat from the heat generating portion 3 can be more easily transmitted to the drug holding portion 1 when the accommodating portion 2 is provided in the heat generating portion 3, and the drug can be more efficiently volatilized. Further, the material of the lid portion 23 may be selected from the group consisting of depositing a metal such as aluminum, cerium oxide, or aluminum oxide with a metal oxide or a metal oxide compound on the thermoplastic resin, and kneading a benzotriazole compound or a benzophenone compound. An ultraviolet absorber such as a salicylate-based compound, a cyanoacrylate-based compound, a nickel-based compound or a triazine-based compound; or at least one type of which is colored by white, blue, green pigment or dye. By performing the above-described processing on the material of the lid portion 23, the light-shielding property is prevented, whereby the drug held by the drug holding portion 1 can be prevented from being decomposed by ultraviolet rays or the like.

The heat generating portion 3 includes a heat generating component 31 that generates heat by oxygen and a package 32 that is permeable. The heat generating composition 31 is a powdery or granular substance which generates heat by an oxidation reaction by oxygen. Specifically, the heat generating composition 31 is an alkaline earth such as metal powder (for example, iron, aluminum, zinc, copper, etc.) or a salt (for example, an alkali metal chloride such as sodium chloride or potassium chloride, calcium chloride or magnesium chloride). Metal chloride, etc., water retaining agent (for example, vermiculite, calcium citrate, cerium oxide gel, cerium oxide porous material, alumina, pulp, wood chips, water absorbing polymer, etc.), reaction accelerator (for example, activated carbon) , carbon black, graphite, etc.), moisture and other composites. Further, by adjusting the blending amounts thereof, the temperature at the time of heat generation and the time of heat generation can be controlled to some extent. As the heat generating portion 3, a so-called disposable warm pack or the like which is a commercially available wide product can be used.

The package body 32 is a bag having a gas permeability that allows oxygen to permeate, and the inside of the package 32 can accommodate the heat generating composition 31. The entire surface or a part of the package 32 has a hole that does not leak the heat generating component 31. Specifically, a material having air permeability such as paper, non-woven fabric, or woven fabric, or a foamed film, plastic, or natural can be used. A porous film sheet formed of a material that does not have air permeability, such as rubber, recycled rubber, synthetic rubber, or metal foil. In order to stably conduct heat to the fixing portion 4 and the second member 22 without biasing the heat generating composition 31 in the inside of the bag shape, it is more preferable to use a plastic film containing fine particles of calcium carbonate or the like to form fine pores. Porous film sheet. At the time of use, the package 32 is heated by the heat generated by the heat generating component 31, and the heat is transmitted from the package 32 to the drug holding unit 1 via the fixing portion 4 and the second member 22.
