Description

  The present invention relates to a drug volatilizer in which a drug volatilization bag in which a volatile drug (aroma component, deodorant component, pest repellent component, etc.) is encapsulated is stored.

  When a liquid absorbent core or a membrane-type drug volatilizer is impregnated with a liquid having a low molecular weight and high volatility, it is volatilized in a short time, making it difficult to exert the effect of the drug for a long time. Thus, for example, as a method of diffusing a highly volatile drug in a room or the like, there is one disclosed in Patent Document 1, for example. In Patent Document 1, a method is employed in which a medicine is kneaded into an incense base material and smoked to fill the space.

JP 2011-12056 A

  However, smoke is very cumbersome, and the space is filled with smoke, so it is difficult to use it in a space with clothes such as a closet or locker, or a space where food is placed. There was also a problem.

  On the other hand, the present inventor has impregnated a liquid-absorbent core or a membrane-type drug volatilizer with a composition containing a highly volatile drug (for example, allyl isothiocyanate) as a method of volatilizing continuously for a long time. Although it was studied to increase the viscosity by adding a thickener such as gelatin to the composition, the drug volatilizer was clogged by the thickener and it was difficult to volatilize the drug efficiently. It was.

  Therefore, the present invention has been proposed in view of the above-described problems, and the object of the present invention is to prevent the chemical volatilization agent from being clogged by a thickener by a simple and labor-saving means, and to be volatile. An object of the present invention is to provide a drug volatilizer capable of exerting the effect of a high drug for a long time.

  As a technical means for achieving the above object, the chemical volatilizer according to the present invention has a viscosity containing a volatile chemical of 30 to 100 mPa.s. a medicine volatilization bag in which the viscous composition of s is encapsulated, and a case having an opening for volatilizing the volatile drug and a closed part in which a receiving part for supporting the drug volatilization bag is projected. The drug volatilization bag has one surface and the other surface opposite to the one surface, and at least one surface is composed of a microporous sheet having a large number of micropores into which the volatile drug can infiltrate, and at least one of the microporous sheets. The receiving portion of the closed portion of the case is brought into contact with a part.

  In the drug volatilizer of the present invention, the drug volatilization bag is composed of a microporous sheet having a large number of micropores in which at least one surface can infiltrate the volatile drug, and at least part of the microporous sheet. Since the protruding receiving part is in contact, the viscous composition has a viscosity of 30 to 100 mPa · s due to the pressing force on the microporous sheet and the capillary phenomenon at the contact part between the microporous sheet and the receiving part. Even if it has such a viscosity, it can infiltrate from the micropores of the microporous sheet and ooze out little by little on the sheet surface, thereby volatilizing the volatile agent to the outside. Thus, according to the chemical volatilizer of the present invention, it is difficult to cause clogging of the chemical volatilized body by a thickener or the like, and the effect of the volatile chemical can be maintained for a long period of time.

  In addition, the microporous sheet, which is the volatilization surface of the chemical volatilization bag, is disposed in the blockage portion located on the opposite side of the case opening by bringing the microporous sheet into contact with the receiving portion of the blockage portion of the case. Will be. As a result, the volatilization concentration of the volatile drug in the closed portion can be increased (can approach the saturated vapor pressure), so that the volatilization of the volatile drug on the surface of the microporous sheet can be delayed and the effect can be further enhanced. The period can be demonstrated.

  The volatile drug in the present invention is desirably an aromatic component or a pest repellent component. The pest repellent component is a low molecule and easily volatilizes, but the effect can be maintained for a long time by being contained in a viscous composition having a specific viscosity.

  The drug volatilization bag according to the present invention preferably includes a structure in which a partition sheet that divides the internal space into two divided spaces is built in, and the two divided spaces communicate with each other on the outer periphery of the partition sheet. In this way, the viscous composition filled in one divided space that is not in contact with the microporous sheet bypasses the outer periphery of the partition sheet by capillary action and enters the other divided space in contact with the microporous sheet. Move and volatilize volatile chemicals from the microporous sheet. Therefore, the effect of the volatile chemical can be maintained for a longer time.

  According to the present invention, at least one surface of the drug volatilization bag is composed of a microporous sheet having a large number of micropores into which the viscous composition can be infiltrated, and is protruded from at least a part of the microporous sheet. The viscous composition has a viscosity of 30 to 100 mPa · s due to the pressing force on the microporous sheet and the capillary phenomenon at the contact portion between the microporous sheet and the receiving part. Even if it is, it can infiltrate from the micropores of the microporous sheet and ooze out little by little on the surface of the sheet. Can have a long time.

  Embodiments of the chemical volatilizer according to the present invention are described in detail below. In the following embodiment, a case where the trash box is attached to the inside of the lid of the trash box for the purpose of scenting and repelling the trash box is exemplified, but the present invention can be applied to a room, a car, or the like.

  1 to 4 illustrate the drug volatilization bag 11, FIG. 1 is an exploded perspective view, FIG. 2 is a perspective view of completion of assembly, FIG. 3 is a cross-sectional view taken along the line AA of FIG. FIG. As shown in FIGS. 1 to 3, the chemical volatilization bag 11 has a double structure including a soft inner bag body 12 and a soft outer bag body 13 that accommodates the inner bag body 12. . 3 and 4, the thickness and the internal space of the inner bag body 12 and the outer bag body 13 are exaggerated.

  The inner bag body 12 having a rectangular shape in plan view is formed into a bag shape with a transparent gas-impermeable film 14, and a viscous composition 15 containing a volatile drug is enclosed therein. Examples of the gas non-permeable film 14 that is the material of the inner bag 12 include thermoplastic synthetic resins such as polyester, polyamide, saponified ethylene-vinyl acetate copolymer, modified polyvinyl alcohol, and polyvinylidene chloride, and aluminum. There are multilayer laminate materials comprising one or more of the following metal foils.

  Examples of the volatile agent include a volatile perfume-containing agent such as paraffin hydrocarbons, glycol ethers, glycols, alcohols, esters, ketones, lactones, aldehydes, and other solvents and aromatic components, N , N-diethyltoluamide (diet), dimethyl phthalate, dibutyl phthalate, 2-ethyl-hexanediol, dibutyl succinate, p-menthane-3,8-diol, allyl isothiocyanate, etc. can be used. .

  The viscous composition 15 may be liquid, gel, sol, or a mixture thereof as long as the viscosity is 30 to 100 mPa · s. If the viscous composition 15 is colored, since the inner bag 12 is formed of the transparent film 14, it is easy to visually check the state of the viscous composition 15 from the outside. The viscous composition 15 is made viscous by a thickener. Examples of the thickener include glycerin, sugar fatty acid ester, wax, thickening polysaccharide, carrageenan, mineral, metal soap, long chain fatty acid, polyvalent metal salt of long chain fatty acid, amino acid derivative, sugar derivative and the like. .

  The inner bag body 12 is formed into a bag shape by folding a single gas-impermeable film 14 in two and heat-sealing the three side portions 16 that are opened by heat sealing. The three side portions 16 are sealed with such a strength that can be broken by an increase in internal pressure due to an external force. In addition, the number and location of the side part 16 sealed so that bag breaking is possible are arbitrary.

  In this inner bag body 12, one gas impermeable film 14 is folded in two and the three side portions 16 are sealed so as to be able to break the bag, but the two gas impermeable films 14 are overlapped. It is also possible to form a bag. In that case, the number and location of the side portions 16 to be sealed so as to be broken are arbitrary.

  The outer bag 13 having a rectangular shape in a plan view is composed of four microporous sheets 17 that constitute one surface and one transparent sheet 18 that constitutes the other surface facing the one, and the four open openings. The side 19 is heat-sealed by heat sealing to form a bag.

  The microporous sheet 17 may constitute a part of one surface other than the entire surface of the outer bag 13. Unlike the case of the inner bag body 12, the four side portions 19 of the outer bag body 13 are sealed so as not to break the bag due to an increase in internal pressure due to an external force. By constituting the other surface side of the outer bag body 13 with the transparent sheet 18, it becomes easy to visually check the inner bag body 12 and the viscous composition 15 from the other surface side.

  In addition, although this embodiment demonstrates the case where the other surface of the outer bag 13 is comprised with the transparent sheet 18, the sheet | seat which comprises the other surface of this outer bag 13 does not necessarily need to be transparent, and is non-transparent. Alternatively, it may be translucent or a microporous sheet.

  The microporous sheet 17 constituting one surface of the outer bag 13 has a large number of micropores into which the viscous composition 15 can infiltrate. That is, unlike the gas permeable film that allows the gas of the volatile drug to permeate, a large number of micropores are physically formed to such an extent that the viscous composition 15 infiltrates and oozes on the sheet surface.

  Examples of the resin used for the microporous sheet 17 include various polyethylenes such as high-density polyethylene, medium-density polyethylene, low-density polyethylene, linear low-density polyethylene, and ultra-high molecular weight polyethylene, and ethylene-vinyl acetate copolymer. Copolymers and saponified products thereof, ethylene-acrylic copolymers, ethylene-propylene copolymers, various olefin resins and copolymers thereof, diene resins and copolymers thereof, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, Examples thereof include semi-synthetic resins such as polystyrene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polyurethane, various acrylic resins, polyvinyl alcohol, polyimide, fluororesin, silicon resin, epoxy resin, and cellophane. As the microporous sheet 17, in particular, a sheet produced by blending an inorganic substance with these resins is preferably used. For example, as the porous sheet 17 produced by blending silica with an olefin resin, Teslin SP600, Teslin SP700, Teslin SP800, Teslin SP1000 (manufactured by PPG Industries, Inc.) and the like are commercially available.

  The resin used for the microporous sheet 17 may be used alone or as a copolymer or a blend. Furthermore, it is good also as a multilayer sheet which used the above-mentioned resin in multiple layers. In order to obtain a multilayer sheet, it is carried out by known means such as dry lamination, co-extrusion, and extrusion lamination. In molding into a sheet, various additives may be kneaded, or stretching or heat treatment may be performed after molding. You may perform coating, vapor deposition, etc. after shaping | molding. When the sheet has two or more layers, one of them may be a metal foil, a metal vapor deposition film, or an inorganic vapor deposition film layer.

  The transparent sheet 18 constituting the other surface of the outer bag 13 is a sheet into which the viscous composition 15 cannot be infiltrated. That is, unlike the above-described microporous sheet 17, the viscous composition 15 does not infiltrate. The transparent sheet 18 may be either a gas permeable film that allows gas of a volatile drug to permeate at a molecular level or a gas impermeable film that blocks gas of a volatile drug.

  As the gas non-permeable film, a film that can be selected from the materials used in the inner bag 12 described above may be used. Examples of the gas permeable film include one or more thermoplastic resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer resin, ionomer resin, ethylene-acrylic acid copolymer resin, and ethylene-α-olefin copolymer resin. There are multi-layer laminate materials comprising

  In the drug volatilization bag 11 having the above-described configuration, as shown in FIG. 4, the internal pressure of the inner bag body 12 is increased by the action of an external force (see the white arrow in the figure), and the three sides 16 sealed are sealed. Is opened and the inner bag 12 is broken, the viscous composition 15 enclosed in the inner bag 12 flows out into the outer bag 13. One side (upper surface in the drawing) of the outer bag body 13 is composed of a microporous sheet 17 having a large number of micropores into which the viscous composition 15 can infiltrate, and at least one of the microporous sheet 17. By allowing a receiving portion 37, which will be described later, to come into contact with the portion, it flows out into the outer bag 13 due to the pressing force on the microporous sheet 17 and the capillary phenomenon at the contact portion between the microporous sheet 17 and the receiving portion 37. Even if the viscous composition 15 has a viscosity of 30 to 100 mPa · s, it volatilizes the volatile agent to the outside by infiltrating from the micropores of the microporous sheet 17 and gradually exuding to the surface of the sheet. (Refer to broken line arrows in the figure).

  Since the microporous sheet 17 constituting one surface of the outer bag body 13 is formed with a large number of micropores so that the volatile drug infiltrates and oozes out on the sheet surface, gas permeability is obtained. Unlike a film, there is no need to select a combination with various volatile chemicals, and there are many volatile chemicals that can be used, and the volatile chemicals can be easily volatilized from the outer bag 13. it can. Thus, since the usable volatile chemical | medical agent is not restrict | limited with respect to the microporous sheet | seat 17 which comprises one surface of the outer side bag body 13, when using a volatile chemical | medical agent, the freedom degree of selection is given. Can be improved.

  In the microporous sheet 17, the viscous composition 15 infiltrates with a large number of micropores and oozes out on the surface of the sheet. The drug can be volatilized well from the outer bag 13. Therefore, it is not necessary to configure both surfaces of the outer bag body 13 with the microporous sheet 17, and only one surface of the outer bag body 13 may be configured with the microporous sheet 17. As a result, the other surface of the outer bag 13 may be made of a sheet that cannot be infiltrated with a volatile drug, such as a gas permeable film or a gas non-permeable film.

  As described above, the viscous composition 15 is made viscous by adding a thickener to the volatile drug. The viscosity of the viscous composition 15 is 30 to 100 mPa.s. s, 40 to 65 mPa.s. s is particularly preferred (viscosity is measured at a vibration viscometer (VM-300-L Seconic) at a measurement temperature of 25 ° C.). Thus, the viscosity of the viscous composition 15 is 30 to 100 mPa.s. s within the range s, and a later-described receiving portion 37 is brought into contact with at least a part of the microporous sheet 17, whereby the microporous sheet 17 is less likely to be clogged by the viscous composition 15, and a volatile agent is formed. Can be efficiently vaporized. The viscosity of the viscous composition 15 is 30 mPa.s. If it is lower than s, the volatile drug will infiltrate too much due to contact with the receiving portion 37, and it will be difficult to exert the effect for a long time. On the contrary, the viscosity of the viscous composition 15 is 100 mPa.s. If it is higher than s, root clogging is likely to occur even if it is in contact with the receiving portion 37.

  Here, the Applicant has sustained the repellent effect of Drosophila melanogaster on the viscous composition 15 prepared by adding gelatin as a thickener to a volatile drug containing 80% by weight of a fragrance and 20% by weight of allyl isothiocyanate. A test was conducted. Specifically, the viscosity is increased to 10,120 mPa.s by adding gelatin to the volatile drug. s and comparative products H and I, and viscosities of 30, 40, 50, 65, 80, 90, and 100 mPa.s. Examples A to G designated s were prepared. 3 g of the comparative product and the practical product were accommodated in the polyethylene inner bag body 12, and the inner bag body 12 (length 50 mm × width 50 mm) was placed in the outer bag body 13 (length 65 mm × width 65 mm). One side of the outer bag 13 is composed of a microporous sheet 17 (Teslin SP600 (thickness 152 μm), Teslin SP700 (thickness 178 μm), Teslin SP800 (thickness 203 μm), Teslin SP1000 (thickness 356 μm)). Has been. After the medicine volatilization bag 11 manufactured in this way is stored in a case 21 (see FIG. 11), which will be described later, the inner bag body 12 is broken (see FIG. 16 and the like), as described later. The quality sheet 17 was brought into contact with the receiving portion 37 and was allowed to stand in a state where the temperature of the viscous composition 15 was maintained at 25 ° C. In addition, about each implementation product and the comparative product, the thickness of the microporous sheet | seat 17 was used 1 type or 2 types as shown in Table 1.

The results of the sustained test are as shown in the table below. In this test, a four-stage evaluation was performed based on the number of days for maintaining the effect of the volatile drug. As the four-level evaluation, “AAA” is 50 days or more, “AA” is 40 days or more and less than 50 days, “A” is 30 days or more and less than 40 days, and “C” is less than 30 days.

  As shown in the above table, the viscosity of the viscous composition 15 is 30 mPa.s. s when “s”, the viscosity is 40, 50, 65 mPa.s. s for "AAA" and a viscosity of 80 mPa.s. s for "AA" and a viscosity of 90,100 mPa.s. It became "A" at the time of s, and it turned out that the effect by a volatile chemical | medical agent lasts for a long time. On the other hand, the viscosity is 10,120 mPa.s. It became "C" at the time of s, and it turned out that it has no effect by a volatile chemical | medical agent for a long time.

  Moreover, the viscosity of the viscous composition 15 is, for example, 40,60 mPa.s. Even if it is set to s, in the state where the microporous sheet 17 of the chemical volatilization bag 11 is not brought into contact with the receiving portion 37 of the case 21, it becomes difficult to make the microporous sheet 17 adhere to the volatile chemical 15. Since an air layer is easily formed between the microporous sheet 17 and the viscous composition 15 and no capillary action occurs at the contact portion between the microporous sheet 17 and the receiving portion 37, the volatilization of the volatile agent is performed. It proved difficult to ensure performance.

  In addition, although the volatile chemical | medical agent of implementation goods AG contains both a fragrance | flavor component and a pest repellent component, even if it contains any 1 type, other volatile chemical | medical agents contain. Even if it is done, it is hard to raise | generate the clogging of the microporous sheet | seat 17 with the viscous composition 15, and the effect by a volatile chemical | medical agent can be maintained for a long time.

  When the chemical volatilization bag 11 described above is used for aroma and pest repellent of a trash box, the chemical volatilization bag 11 is used as a chemical volatilizer stored in a resin case 21 such as plastic.

  5 to 10 illustrate a case 21, FIG. 5 illustrates a case 21 having a two-part structure in which two case halves 23 and 24 are abutted, (A) is a top view, and (B) is a front view. FIG. 6C is a bottom view, FIG. 6 is a cross-sectional view taken along line BB in FIG. 5A, FIG. 7 is a bottom view of one case half 23 (hereinafter referred to as the upper case), FIG. Is a cross-sectional view taken along the line CC of FIG. 7, FIG. 9 is a top view of the other case half 24 (hereinafter referred to as the lower case), and FIG. 10 is a cross-sectional view taken along the line DD of FIG. .

  As shown in FIGS. 5A to 5C and FIG. 6, the case 21 has a two-part structure in which two circular dish-shaped upper and lower cases 23 and 24 are abutted. The case 21 has the following outer peripheral portions of the upper case 23 shown in FIGS. 7 and 8 and the lower case 24 shown in FIGS. 9 and 10 so that the used medicine volatilization bag 11 can be replaced as follows. The structure is provided.

  The upper and lower cases 23, 24 can be aligned with a structure in which the pin 25 of the upper case 23 is inserted into the concave hole 26 of the lower case 24, and the claw 27 of the upper case 23 and the claw 28 of the lower case 24 are The upper and lower cases 23 and 24 can be separated by a one-touch type by a hooking and locking structure. In this case 21, the fitting structure is separable by a hooking and locking structure between the claws 27 and 28, but the used medicine volatilization bag 11 can be exchanged by making the hinge structure openable and closable. May be.

  The upper case 23 is provided with a circular pressing portion 29 that applies an external force to the inner bag body 12 of the drug volatilization bag 11 via the outer bag body 13 at the central portion thereof. The pressing portion 29 is integrally formed in a state where it is cantilevered and supported by the upper case 23 via a flexible connecting portion 30 and can be pushed in by being disposed in the opening 31 of the upper case 23. Yes.

  A plurality of volatilization holes 32 that are openings for releasing a volatile drug are disposed around the circumference of the pressing portion 29 in the circumferential direction. Further, the upper case 23 is provided with four corners 33 (see FIG. 9) of the outer bag body 13 of the drug volatilization bag 11 positioned and placed on the lower case 24 when the upper and lower cases 23 and 24 meet. Four pushing ribs 34 to be pushed inwardly are integrally formed at portions corresponding to the four corners 33 of the outer bag 13.

  The lower case 24 is integrally provided with four support ribs 35 on which the outer bag 13 of the chemical volatilization bag 11 is placed. In addition, four position regulating ribs 36 that integrally position the outer bag body 13 by being in contact with the side portions 19 of the outer bag body 13 are erected integrally. The front end portion of the position restricting rib 36 has a hook shape, and the outer bag body 13 is pressed by the hook-shaped front end portion to prevent the outer bag body 13 from floating, thereby stabilizing the position restriction.

  A receiving portion 37 that supports the inner bag body 12 of the drug volatilization bag 11 to which an external force is applied by the pressing portion 29 via the outer bag body 13 is integrally provided at the central portion of the lower case 24. The receiving portion 37 has a support surface 38 that is inclined so as to face the pressing portion 29 that has been pushed in, and the medicine volatilization bag 11. The receiving portion 37 has a double structure of the inner circular rib 39 and the outer circular rib 40, and the support surface 38 is at the upper end portion of the inner circular rib 39 and the cross-shaped rib 41 and the outer circular rib 40 located inside thereof. It is configured. The upper case 23 has the opening 31 and the volatilization hole 32, whereas the lower case 24 does not have the opening 31 and the volatilization hole 32, and constitutes a closed part.

  In addition, an adhesive tape 42 for attaching the drug volatilizer 22 to the inner side of the lid of the trash box is provided at the outer central portion of the lower case 24. The lower case 24 is not provided with a volatilization hole 32. Since the adhesive tape 42 for attaching the chemical volatilizer 22 to the inside of the lid of the trash box is attached to the lower case 24, the lower case 24 has no volatilization hole 32, so that the chemical volatilization bag 11 can be used at the time of use. With the volatile chemicals to be volatilized, it is possible to prevent the adhesive force of the adhesive tape 42 disposed in the vicinity of the lower case 24 from being lowered and the material of the lid of the trash can from being damaged.

  The point of loading the aforementioned chemical volatilization bag 11 into the case 21 described above will be described in detail below with reference to FIGS. FIGS. 11 to 13 illustrate a drug volatilizer 22 in which the drug volatilization bag 11 is assembled to the above-described case 21, FIGS. 11 and 12 are exploded perspective views, and FIG.

  The rectangular drug volatilization bag 11 is placed on the support rib 35 of the lower case 24 so that the microporous sheet 17 of the outer bag 13 faces the lower case 24 side, and each side of the drug volatilization bag 11 is placed. The chemical volatilization bag 11 is positioned by bringing the portion 19 into contact with the position regulating rib 36 from the side. The upper case 23 is aligned with the lower case 24 on which the medicine volatilization bag 11 is positioned and placed with a structure including the pin 25 of the upper case 23 and the concave hole 26 of the lower case 24, and the claw 27 of the upper case 23 The lower case 24 is fitted with a hook and lock structure with the claw 28. In this way, the assembly of the chemical volatilization bag 11 to the case 21 is completed.

  When the upper and lower cases 23 and 24 meet, the four corners 33 of the outer bag 13 of the drug volatilization bag 11 positioned and placed on the lower case 24 are positioned on or near the outer peripheral portions of the upper and lower cases 23 and 24. For this reason (see FIG. 9), there is a possibility that the upper and lower cases 23 and 24 may be bitten between the outer peripheral portions or protrude from the outer peripheral portions.

  Therefore, the pushing ribs 34 provided on the upper case 23 push the four corners 33 of the outer bag 13 of the chemical volatilization bag 11 into the lower case 24 when the upper and lower cases 23 and 24 meet. This prevents the four corners 33 of the outer bag 13 of the chemical volatilization bag 11 from being caught between the outer peripheral parts of the upper and lower cases 23, 24 and protruding from the outer peripheral parts. This prevents the outer bag 13 from being broken by the protrusion and the viscous composition 15 from leaking to the outside.

  When the chemical volatilizer 22 described above is used for the aroma of the trash box or the repellent of insect pests, as shown in FIGS. 14 and 15, the chemical volatilizer is used by using the adhesive tape 42 provided in the lower case 24. 22 is attached to the inside of the lid 44 of the trash box 43. That is, the chemical volatilizer 22 is mounted in an upside down state in which the upper case 23 faces downward and the lower case 24 faces upward.

  In this attached state, the drug volatilization container 22 is held in a substantially horizontal state, and the drug volatilization bag 11 accommodated in the drug volatilization container 22 is held with the microporous sheet 17 facing upward. On the other hand, before or after attaching the chemical volatilization container 22 to the lid 44 of the trash box 43, the inner bag 12 of the chemical volatilization bag 11 is broken by the following operation.

  First, an external force is applied to the inner bag body 12 via the outer bag body 13 of the drug volatilization bag 11 by pushing the pressing portion 29 provided in the upper case 23 of the drug volatilization container 22 into the container. By applying this external force, the internal pressure of the inner bag body 12 is increased, and the inner bag body 12 is broken by the increase of the internal pressure. Since the three side portions 16 are sealed with such a strength that the inner bag body 12 can be broken by an increase in internal pressure due to external force, a part or all of the three side portions 16 are opened. Done.

  When the external force is applied by the pressing portion 29, as shown in FIG. 16, the pressing portion 29 provided on the upper case 23 via the connecting portion 30 has the connecting portion 30 having flexibility. It is pushed into the container by the bending of 30. Due to the pressing operation of the pressing portion 29, the drug volatilization bag 11 is sandwiched between the receiving portion 37 of the lower case 24 and the pressing portion 29.

  The support surface 38 of the receiving portion 37 composed of the inner circular rib 39 and the cross-shaped rib 41 and the outer circular rib 40 is inclined so as to face the pressing portion 29 inclined by the pushing operation through the drug volatilization bag 11. Therefore, since the pressing surface 45 of the pressing part 29 and the support surface 38 of the receiving part 37 are parallel, the entire surface of the pressing part 29 contacts the drug volatilization bag 11.

  Thus, since the contact area of the press part 29 and the medicine volatilization bag 11 can be ensured to the maximum, a sufficient external force can be applied by the press part 29, and the inner bag body 12 of the drug volatilization bag 11. Can be surely broken. In addition, the inner bag body 12 is broken with a simple structure including the pressing portion 29 of the upper case 23 and the receiving portion 37 of the lower case 24 and provided in the case 21 located outside the drug volatilization bag 11. be able to.

  As the inner bag body 12 is broken, the viscous composition 15 enclosed in the inner bag body 12 flows into the outer bag body 13 as shown in FIG. The outer bag 13 is composed of a microporous sheet 17 having a large number of micropores into which the viscous composition 15 can be infiltrated on one surface facing upward, and a receiving portion 37 abuts against a part of the microporous sheet. Therefore, the viscous composition 15 has a viscosity of 30 to 100 mPa · s due to the pressing force to the microporous sheet 17 and the capillary phenomenon at the contact portion between the microporous sheet 17 and the receiving portion 37. Also, it can infiltrate from the micropores of the microporous sheet 17 and ooze out little by little on the surface of the sheet, whereby the volatile chemicals are volatilized to the outside.

  The volatile chemical volatilized to the outside of the outer bag 13 is released to the outside of the case through the volatilization hole 32 and the opening 31 provided in the upper case 23 of the chemical volatilization container 22. In this way, by filling the inside of the trash box 43 with the volatile chemical volatilized to the outside of the case, the chemical volatilization container 22 functions as an aroma and pest repellent of the trash box 43.

  In addition, if the viscous composition 15 enclosed in the inner bag body 12 of the drug volatilization bag 11 is colored, the surface facing the upper case 23 side of the outer bag body 13 is constituted by the transparent sheet 18, Since the viscous composition 15 that has flowed into the outer bag 13 can be visually observed from the volatilization hole 32 and the opening 31 of the upper case 23, it is easy to check the remaining amount of the viscous composition 15.

  As a result, when the drug volatilizer 22 is disposable, the disposal time of the drug volatilizer 22 can be recognized quickly and easily. Moreover, when the medicine volatilizer 22 can be refilled, the replacement time of the medicine volatilization bag 11 can be recognized quickly and easily.

  In addition, since the chemical volatilization bag 11 is composed of the soft inner bag body 12 and the outer bag body 13, even if the viscous composition 15 is reduced due to the volatilization of the volatile drug, it is accompanied by a decrease in the volatile drug. The microporous sheet 17 of the outer bag 13 is in close contact with the viscous composition 15 by internal decompression. Furthermore, since the microporous sheet 17 is in contact with the receiving portion 37 provided in a protruding manner on the lower case 24, it becomes easy to make the microporous sheet 17 adhere to the viscous composition 15, and the microporous sheet 17. It is difficult to form an air layer between and the viscous composition 15, and a capillary phenomenon also occurs at the contact portion between the microporous sheet 17 and the receiving portion 37, so that the viscous composition 15 is formed on the surface of the microporous sheet 17. Easy to ooze out.

  Thus, an air layer is not formed between the microporous sheet 17 and the viscous composition 15, and the microporous sheet 17 and the viscous composition 15 are always in contact with each other, and the microporous sheet 17 and the receiving portion 37 are in contact with each other. Since the capillary phenomenon also occurs at the contact portion with the liquid, the viscous composition 15 infiltrates into the microporous sheet 17 and oozes out to the surface of the sheet even if the viscous composition 15 is reduced. It can avoid remaining.

  Note that the contact between the microporous sheet 17 and the receiving portion 37 does not have to be the entire microporous sheet 17, and even a part of the microporous sheet 17 is caused by a capillary phenomenon that occurs in the contact portion. The volatile drug will ooze out to the surface of the microporous sheet 17 and efficiently evaporate to the outside.

  Further, by bringing the microporous sheet 17 of the outer bag 13 into contact with the receiving portion 37 of the lower case 24, the microporous sheet 17 from which the volatile chemicals are volatilized becomes the volatilization hole 32 and the opening of the upper case 23. It will be arranged on the opposite side to the part 31. As a result, it is possible to increase the volatilization concentration of the volatile drug in the lower case 24, which is a closed part (can approach the saturated vapor pressure), so that the volatilization of the volatile drug on the surface of the microporous sheet 17 is delayed. And the effect can be exhibited for a longer period of time. In addition, when the volatile agent contains a particularly volatile agent such as allyl isothiocyanate, the vapor pressure in the lower case 24 is more likely to be increased by reducing the opening area of the volatilization hole 32, and the effect is improved. Further, it can be exhibited for a long time.

  In the usage form of the chemical volatilizer 22 described above, the chemical volatilization bag 11 is held in a horizontal state inside the lid 44 of the waste bin 43 in order to avoid the aroma and pest repellent of the waste bin 43, that is, in a so-called horizontal state. . Thus, in the usage form of the drug volatilizer 22 in which the drug volatilization bag 11 is placed in the case 21 in the horizontal state, as described above, one surface of the outer bag body 13 formed of the microporous sheet 17 is on the upper side. By disposing the chemical volatilization bag 11 toward the surface, the viscous composition 15 infiltrated by a large number of micropores in the microporous sheet 17 and exuded on the sheet surface or the volatilized volatile chemical becomes droplets in the case It can suppress falling to the inside or the outside of the case.

  In addition, although the above embodiment demonstrated the usage form of the chemical volatilizer 22 which arrange | positions the chemical volatilization bag 11 in the case 21 in a horizontal state, this invention is not limited to this, The chemical volatilization bag 11 The usage form of the chemical volatilizer which arrange | positions in a case in a vertical state may be sufficient. In this case, even if the viscous composition 15 or the volatilized volatile agent that has infiltrated through the numerous micropores of the microporous sheet 17 and oozed out on the sheet surface becomes a droplet, the droplet is received by the case. , Can be prevented from falling outside the case.

  Moreover, in the above embodiment, the chemical volatilization bag 11 has a double structure including the inner bag body 12 and the outer bag body 13. In the double-structure drug volatilization bag 11, after the viscous composition 15 flows out from the inner bag body 12 to the outer bag body 13 due to the bag breaking of the inner bag body 12, the inner bag body 12 comes into close contact with the sheet shape. (See FIG. 4 and FIG. 17). Thus, the sheet-like inner bag 12 functions as a partition sheet that partitions the inner space of the outer bag 13 into two divided spaces m and n.

  That is, the inner bag body 12 functioning as a partition sheet communicates the two divided spaces m and n on the outer periphery thereof. As a result, the viscous composition 15 filled in the lower divided space m that is not in contact with the microporous sheet 17 bypasses the outer periphery of the inner bag body 12 (partition sheet) by capillary action, and thus the microporous sheet 17. Volatile chemicals are volatilized by moving into the upper divided space n in contact with the liquid and infiltrating from the micropores of the microporous sheet 17 and oozing out onto the sheet surface. Therefore, the effect of the volatile chemical can be maintained for a longer time.

  In addition, although the above embodiment demonstrated the case where the inner bag body 12 was made to function as a partition sheet in the double-structure medicine volatilization bag 11, this invention is not limited to this, A single-structure medicine Volatilization bags, that is, the inside of the outer bag body 13 in the above-described embodiment, the viscous composition 15 is enclosed, and one partition sheet that divides the inner space of the outer bag body 13 into two divided spaces m and n is incorporated. It may be a structure.

  The present invention is not limited to the above-described embodiments, and can of course be implemented in various forms without departing from the gist of the present invention. It includes the equivalent meanings recited in the claims and the equivalents recited in the claims, and all modifications within the scope.
