Description

[Technical Field]

[0001] The present invention relates to a drug volatilizer comprising a drug volatilizer that holds a volatile drug, a container that stores the drug volatilizer, and a hook portion that is connected to the container and can be hooked onto a hanger bar. [Background technology]

[0002] BACKGROUND ART Conventionally, chemical volatilizers that are hung from hanger bars (hanger pipes) for hanging clothes and the like in wardrobes, closets, and the like are known (see, for example, Patent Document 1).

[0003] The drug volatilizer described in Patent Document 1 comprises a drug volatilizer that holds a volatile drug, a container that stores the drug volatilizer, and a hook attached to the upper side of the container, and is configured for use by hanging the hook on a hanger bar. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-14345 Summary of the Invention [Problem to be solved by the invention]

[0005] In the chemical volatilizer described in Patent Document 1, the hook is loosely attached to the hanger bar, making it impossible to fix the container at the desired position relative to the hanger bar. Therefore, due to the action of gravity, the container is limited to use in a state where it is suspended below the hanger bar. As a result, the container may become buried among the clothing or other items hanging from the hanger bar. In this case, the diffusion of the chemical is hindered by the surrounding clothing or other items, preventing the chemical from fully exerting its efficacy throughout the treatment space, or the container may be hidden by the clothing or other items, making it difficult to confirm where the container is located. Therefore, it can be said that there is room for improvement in the chemical diffusion effect and the visibility of the container.

[0006] The present invention has been made in consideration of the above problems, and aims to provide a drug volatilization device that increases the degree of freedom in positioning the container relative to the hanger bar. [Means for solving the problem]

[0007] The characteristic configuration of the chemical volatilizer according to the present invention to solve the above problems is as follows: A drug volatilizer comprising a drug volatilizer containing a volatile drug, a container for storing the drug volatilizer, and a hook portion connected to the container and capable of being hung on a hanger bar, The hook portion includes a main hook and an auxiliary hook that forms a pair with the main hook, The main hook and the auxiliary hook cooperate to clamp the hanger bar, thereby fixing the container to the hanger bar.

[0008] With this chemical volatilizer, the position at which the container is fixed to the hanger bar can be changed by changing the position at which the main hook and auxiliary hook clamp the hanger bar, thereby increasing the degree of freedom in positioning the container relative to the hanger bar.

[0009] In the drug volatilization device according to the present invention, The main hook acts to draw the container to the hanger bar; The auxiliary hook preferably acts to pull the container away from the hanger bar.

[0010] With this configuration of drug volatilizer, the action of the main hook pulling the container toward the hanger bar and the action of the auxiliary hook pulling the container away from the hanger bar interact to securely clamp the hanger bar between the main hook and the auxiliary hook, thereby stably fixing the container to the hanger bar.

[0011] In the drug volatilization device according to the present invention, the container has a facing portion that faces the hanger bar when the hook portion is hooked, the main hook and the auxiliary hook are supported by the container so as to sandwich the facing portion, It is preferable that the main hook is elastically deformable in a direction away from the opposing portion, and the auxiliary hook is elastically deformable in a direction toward the opposing portion.

[0012] With this configuration of chemical volatilizer, when the hook portion is attached by moving the hook portion relative to the hanger bar so as to push the hanger bar between the main hook and auxiliary hook that make up the hook portion, the main hook elastically deforms in a direction away from the portion of the container facing the hanger bar while abutting the outer peripheral surface of the hanger bar, and at the same time, the auxiliary hook elastically deforms in a direction toward the facing portion of the container while abutting the outer peripheral surface of the hanger bar. When the main hook elastically deforms in a direction away from the facing portion, an elastic force is applied from the main hook to the hanger bar in a direction toward the facing portion of the container, and as a result, a force is applied from the main hook to the container that draws the container to the hanger bar. On the other hand, when the auxiliary hook elastically deforms in a direction toward the facing portion, an elastic force is applied from the auxiliary hook to the hanger bar in a direction away from the facing portion of the container, and as a result, a force is applied from the auxiliary hook to the container that pulls the container away from the hanger bar. In this way, the action of the main hook pulling the container to the hanger bar and the action of the auxiliary hook pulling the container away from the hanger bar interact to securely clamp the hanger bar between the main hook and the auxiliary hook, thereby stably fixing the container to the hanger bar.

[0013] In the drug volatilization device according to the present invention, It is preferable that the tip of the main hook and the tip of the auxiliary hook are configured to face in opposite directions.

[0014] With this chemical volatilizer, the tips of the main hook and the auxiliary hook are configured to face in opposite directions, so even if the main hook and the auxiliary hook are extended circumferentially around the hanger bar, the tips of the main hook and the auxiliary hook do not butt against each other. This makes it possible to extend the main hook and the auxiliary hook along the circumferential direction of the hanger bar, making it easy to expand the clamping area in which the main hook and the auxiliary hook clamp the hanger bar. This ensures that the clamping force from the main hook and the auxiliary hook acts in the radial direction of the hanger bar, allowing the hanger bar to be more securely clamped by the main hook and the auxiliary hook.

[0015] In the drug volatilization device according to the present invention, The hook portion is preferably configured so as to be fixable at any angular position relative to the axis of the hanger bar.

[0016] With this configuration of drug volatilizer, the hook portion can be fixed at any angle relative to the axis of the hanger bar, so the container can be fixed in a position where it will not be buried in clothing, etc., in a position suitable for diffusing the drug, in a position where it is easy to see where it is located, or in a position where it will not interfere with taking clothes, etc. in and out.

[0017] In the drug volatilization device according to the present invention, The outer diameter of the hanger bar is 25 mm, When the hook portion is fixed to the hanger bar so that the container is positioned vertically above the hanger bar, When the container is urged downward at a position 55 mm horizontally away from the axis of the hanger bar, the urging force at which the container begins to rotate is preferably 0.1 N or more.

[0018] With this configuration of drug volatilizer, when the hanger bar has an outer diameter of 25 mm, it is possible to prevent the container from unintentionally rotating around the hanger bar, and when the container is intentionally rotated around the hanger bar, it can be easily rotated, making it easy to adjust the relative position of the container around the hanger bar.

[0019] In the drug volatilization device according to the present invention, The outer diameter of the hanger bar is 32 mm, When the hook portion is fixed to the hanger bar so that the container is positioned vertically above the hanger bar, When the container is urged downward at a position 55 mm horizontally away from the axis of the hanger bar, the urging force at which the container begins to rotate is preferably 50 N or less.

[0020] With this configuration of drug volatilizer, if the urging force is 50 N or less for a hanger bar with an outer diameter of 32 mm, it is easy to rotate the container around the hanger bar and there is little risk of damaging the hanger bar.

[0021] In the drug volatilization device according to the present invention, It is preferable that the force required to attach the hook portion to the hanger bar is 0.5 to 30.0 N, and the force required to remove the hook portion from the hanger bar is 1.0 to 35.0 N.

[0022] With this configuration of drug volatilizer, the hook portion can be easily attached and detached from the hanger bar without requiring excessive operating force.

[0023] In the drug volatilization device according to the present invention, The hook portion is preferably a resin molded body containing at least one resin selected from the group consisting of polyethylene terephthalate, polyethylene, and polypropylene.

[0024] In the chemical volatilizer of this configuration, the hook portion is a resin molded body containing at least one resin selected from the group consisting of polyethylene terephthalate, polyethylene, and polypropylene, and therefore has appropriate hardness and flexibility. This allows the hook portion to be easily attached and detached from the hanger bar, and when the hook portion is attached to the hanger bar, the container can be fixed to the hanger bar.

[0025] In the drug volatilization device according to the present invention, The volatile chemical is preferably at least one selected from the group consisting of insect repellents, aromatics, deodorants, antifungal agents, and antibacterial agents.

[0026] The chemical volatilizer of this configuration can prevent clothes and the like from being eaten by insects, add fragrance to a space, remove specific bad odors, and prevent the occurrence or proliferation of mold. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0028] The present invention will be described below with reference to the drawings. However, the present invention is not intended to be limited to the embodiments described below or the configurations shown in the drawings.

[0029] <Overall structure> FIG. 1 shows a chemical volatilization device 1 according to one embodiment of the present invention. FIG. 1(a) is a front view, and FIG. 1(b) is a rear view.

The container 3 and hook portion 4 can be fabricated by known resin molding methods such as injection molding using resins such as polyethylene terephthalate, polyethylene, and polypropylene, but are not limited thereto. In this embodiment, the hook portion 4 is fabricated from a resin molded body containing at least one selected from the group consisting of polyethylene terephthalate, polyethylene, and polypropylene, thereby providing appropriate hardness and flexibility. This allows the hook portion 4 to be easily attached and detached to the hanger bar HB, and the container 3 can be secured to the hanger bar HB when the hook portion 4 is attached to the hanger bar HB.

[0030] <Volatile agents> The volatile agent may be an insect repellent, an aromatic, a deodorizer, an antifungal agent, an antibacterial agent, or the like, and may be used alone or in combination, but is not particularly limited thereto. For example, when an insect repellent effect is desired, it is preferable to use a pyrethroid compound as the volatile agent, and in particular, pyrethroid compounds that are volatile at room temperature, such as metofluthrin, profluthrin, empenthrin, and transfluthrin, which have high volatility and control effect, are suitable. Note that these volatile pyrethroid compounds exist as various optical isomers or geometric isomers, and any of these isomers can be used. Furthermore, various additives can be used, or they can be used in combination with known hardly volatile agents, etc.

[0032] Examples of deodorizers include plant extracts such as green tea extract and persimmon extract, as well as hiba oil, cypress oil, bamboo extract, mugwort extract, tung oil, and pyruvic acid esters such as ethyl pyruvate and phenylethyl pyruvate. These deodorizers can be used alone or in combination. Deodorizers made of porous materials such as activated carbon and zeolite can also be used. Furthermore, deodorizers containing metal ions such as silver, copper, and zinc, or titanium oxide photocatalysts, processed into plates, granules, sheets, etc., and carrying a volatile deodorizer can also be used.

[0033] Examples of antifungal agents include 2-octyl-4-isothiazolin-3-one, 5-chloro-2-methyl-4-isothiazolin-3-one, 3-methyl-4-isopropylphenol, p-chloro-m-xylenol, ortho-phenylphenol, N-(fluorodichloromethylthio)-phthalimide, hinokitiol, thymol, tetrahydrolinalool, and carvacrol.

[0034] Examples of antibacterial agents include hinokitiol, tetrahydrolinalool, eugenol, citronellal, allyl isothiocyanate, carvone, pinene, terpene alcohol, 3-methyl-4-isopropylphenol, thymol, and carvacrol.

[0035] <Drug volatilization body> For example, a carrier in which the volatile drug is impregnated or kneaded into a substrate can be used as the drug volatilizer 2. Examples of materials for the substrate include paper, pulp, natural fibers, synthetic fibers, resin bodies, resin sheets, inorganic or organic porous bodies, etc.

[0036] <Container> As shown in Figures 1(a) and 1(b), the container 3 comprises a front-side container portion 3a (see Figure 1(a)) constituting the front side portion and a rear-side container portion 3b (see Figure 1(b)) constituting the rear side portion. The container portions 3a and 3b are configured to be assembled by sandwiching the drug volatilizer 2 between them and fastening them together using a known fastening means (not shown). The front-side container portion 3a and the rear-side container portion 3b each have a required volatilization hole 5. As shown in Figure 1(a), the container 3 has a rectangular shape in front view, with a pair of first long side portion 11 and a pair of second long side portion 12 and a pair of first short side portion 13 and a pair of second short side portion 14 forming a right angle with each other. The shape of the container 3 is not particularly limited as long as it can accommodate the drug volatilizer 2, and may be, for example, an oval shape in front view, in addition to a rectangular shape in front view.

[0037] Figure 2 shows the chemical volatilizer 1 attached to a hanger bar HB. Figure 2(a) is a front view, and Figure 2(b) is an enlarged view of part A in Figure 2(a). In the state shown in Figure 2(a) where the hook portion 4 is hooked onto the hanger bar HB, of the first long side portion 11 and the second long side portion 12 of the container 3, the first long side portion 11 arranged closer to the hanger bar HB includes an opposing portion 15 that faces the hanger bar HB at approximately the center position in the longitudinal direction.

[0038] <Hook part> As shown in FIG. 2(b), the hook portion 4 includes a main hook 21 and an auxiliary hook 22 that forms a pair with the main hook 21, and is integrally connected to the first long side portion 11 of the container 3. The main hook 21 and the auxiliary hook 22 are supported on the container 3 so as to sandwich the opposing portion 15. In the hook portion 4, the main hook 21 is configured to be elastically deformable in a direction away from the opposing portion 15, and the auxiliary hook 22 is configured to be elastically deformable in a direction approaching the opposing portion 15.

[0039] <Main hook> The main hook 21 has a support portion 31, a vertical shaft portion 32, an outer curved portion 33, and a barbed portion 34. The support portion 31 is integrally joined to the first long side portion 11 on one side (the right side in FIG. 2(b)) of a projected clamping area PR, which is obtained by projecting a clamping area R, in which the main hook 21 and auxiliary hook 22 clamp the hanger bar HB, onto the facing portion 15 (hereinafter, the support portion 31 will be referred to as the "one-side support portion 31"). The one-side support portion 31 is connected to the vertical shaft portion 32, which extends perpendicular to the first long side portion 11, with an outer curved portion 33 that is curved so as to be able to contact the outer periphery of the hanger bar HB. The barbed portion 34, which is bent outward, is connected to the tip of the outer curved portion 33.

[0040] <Auxiliary hook> The auxiliary hook 22 has a support portion 41, an inclined shaft portion 42, and an inner curved portion 43. The support portion 41 is integrally joined to the first long side portion 11 on the other side (the left side in FIG. 2(b)) of the projected clamping area PR (hereinafter, the support portion 41 will be referred to as the "other-side support portion 41"). The other-side support portion 41 is connected to an inner curved portion 43 that is curved so as to be able to come into contact with the outer peripheral surface of the hanger bar HB via an inclined shaft portion 42 that inclines in a direction away from the first long side portion 11 toward the side where the one-side support portion 31 is provided (the right side in FIG. 2(b)).

[0041] As shown in Fig. 2(b), the tip of the outer curved portion 33 faces the side where the other-side support portion 41 is provided (the left side in Fig. 2(b)). On the other hand, the tip of the inner curved portion 43 faces the side where the one-side support portion 31 is provided (the right side in Fig. 2(b)). Thus, in the hook portion 4, the tip of the main hook 21 and the tip of the auxiliary hook 22 are configured to face in opposite directions.

[0042] In this embodiment, so that the hook portion 4 can be hooked (attached) to the hanger bar HB to secure the container 3, the diameter of an imaginary circle VC inscribed in the outer curved portion 33 and the inner curved portion 43 in the natural state (not attached to the hanger bar HB) as shown in FIGS. 1(a) and 1(b) is set smaller than the outer diameter of the hanger bar HB. When the diameter of the imaginary circle VC is D1 and the outer diameter of the hanger bar HB is D2, the ratio of D2 to D1 (D2 / D1) is preferably in the range of 1.03 to 1.65, more preferably 1.08 to 1.58, and particularly preferably 1.14 to 1.50. In this example, since the outer diameter of a commonly used hanger bar HB is approximately 25 to 32 mm, the diameter of the imaginary circle VC is set to approximately 22 mm so that the hook portion 4 can be attached to a hanger bar HB having an outer diameter of approximately 25 to 32 mm to secure the container 3.

[0043] In this embodiment, when the hook portion 4 is fixed to the hanger bar HB having an outer diameter of 25 to 32 mm so that the container 3 is positioned vertically above the hanger bar HB (see FIG. 4), the biasing force at which the container 3 begins to rotate when the container 3 is biased downward at a position 55 mm horizontally away from the axis (center line CL) of the hanger bar HB is set to 0.1 N or greater. This prevents the container 3 from unintentionally rotating around the hanger bar HB, and also facilitates intentional rotation of the container 3 around the hanger bar HB, making it easy to adjust the relative position of the container 3 around the hanger bar HB. The biasing force at which the container 3 begins to rotate is more preferably 0.2 N or greater, and particularly preferably 0.4 N or greater. The upper limit of the biasing force at which the container 3 begins to rotate is preferably 50 N, more preferably 20 N, and particularly preferably 10 N. If the biasing force is 50 N or less, it is easy to rotate the container 3 around the hanger bar HB, and there is little risk of damaging the hanger bar HB.

[0044] In this embodiment, the force required to attach the hook portion 4 to a hanger bar HB having an outer diameter of 25 to 32 mm by pushing it downward from above with the container 3 positioned to the side as shown in Fig. 5 is 5.4 to 14.2 N, and the force required to detach the hook portion 4 from the hanger bar HB by pulling it upward in the same position is set to 10.4 to 12.6 N. This allows the hook portion 4 to be easily attached to and detached from the hanger bar HB without requiring excessive operating force. The force required to attach the hook portion 4 to the hanger bar HB is preferably 0.5 to 30.0 N, more preferably 2.0 to 25.0 N, even more preferably 3.0 to 20.0 N, and particularly preferably 4.0 to 17.5 N. On the other hand, the force required to remove the hook portion 4 from the hanger bar HB is preferably 1.0 to 35.0N, more preferably 2.5 to 30.0N, even more preferably 3.5 to 25.0N, and particularly preferably 4.5 to 20.0N.

[0045] In the chemical volatilizer 1 configured as described above, as shown in FIG. 2(a), the hook portion 4 is attached to the hanger bar HB as follows: First, the barb portion 34 and the inclined shaft portion 42 are abutted against the outer peripheral surface of the hanger bar HB. Next, a pushing force is applied from the hook portion 4 to the hanger bar HB, and the hook portion 4 is moved relative to the hanger bar HB so as to push the hanger bar HB between the main hook 21 (outer curved portion 33) and the auxiliary hook 22 (inner curved portion 43). Then, the gap between the outer curved portion 33 and the inner curved portion 43 widens due to the guidance provided by the inclined surfaces of the barb portion 34 and the inclined shaft portion 42, and the expanding force acting to widen the gap between the outer curved portion 33 and the inner curved portion 43 due to the inclined surfaces dividing the pushing force. At the same time, the hanger bar HB moves between the outer curved portion 33 and the inner curved portion 43. At this time, the outer curved portion 33 abuts against the outer peripheral surface of the hanger bar HB on the side relatively farther from the container 3, while the main hook 21 elastically deforms in a direction away from the facing portion 15. At the same time, the inner curved portion 43 abuts against the outer peripheral surface of the hanger bar HB on the side relatively closer to the container 3, while the auxiliary hook 22 elastically deforms in a direction toward the facing portion 15. This elastic deformation of the main hook 21 and the auxiliary hook 22 continues until the relative distance between the tip of the outer curved portion 33 and the base of the inner curved portion 43 matches the outer diameter of the hanger bar HB. Then, when a pushing force is applied from the hook portion 4 to the hanger bar HB so as to further press the hanger bar HB between the outer curved portion 33 and the inner curved portion 43, the hook portion 4 is moved relative to the hanger bar HB. As the outer curved portion 33 and the inner curved portion 43 each try to return to their original shapes before elastic deformation, they come into contact and pressed against the outer peripheral surface of the hanger bar HB. In this manner, the hook portion 4 is attached to the hanger bar HB.

[0046] With the hook portion 4 attached to the hanger bar HB as described above, an elastic force acts on the hanger bar HB from the outer curved portion 33, and an elastic force also acts on the hanger bar HB from the inner curved portion 43. As the elastic force acts on the hanger bar HB from the outer curved portion 33, a force that attracts the container 3 to the hanger bar HB acts on the container 3 from the outer curved portion 33 via the vertical shaft portion 32 and one-side support portion 31. On the other hand, as the elastic force acts on the hanger bar HB from the inner curved portion 43, a force that pulls the container 3 away from the hanger bar HB acts on the container 3 from the inner curved portion 43 via the inclined shaft portion 42 and the other-side support portion 41. In this way, the action of the main hook 21 that attracts the container 3 to the hanger bar HB and the action of the auxiliary hook 22 that pulls the container 3 away from the hanger bar HB interact to securely hold the hanger bar HB between the main hook 21 and the auxiliary hook 22, thereby stably fixing the container 3 to the hanger bar HB.

[0047] According to the chemical volatilization device 1 of this embodiment, the container can be fixed by attaching the hook portion to a commonly used hanger bar having an outer diameter of 25 to 32 mm. Furthermore, according to the chemical volatilization device 1 of this embodiment, the fixed position of the container 3 relative to the hanger bar HB can be changed by changing the position at which the hanger bar HB is clamped by the main hook 21 and the auxiliary hook 22. Therefore, the degree of freedom in positioning the container 3 relative to the hanger bar HB can be increased.

[0048] FIG. 3 is a diagram illustrating the positioning of the container 3 relative to the hanger bar HB. In the chemical volatilizer 1 of this embodiment, the hanger bar HB is clamped by an outer curved portion 33 and an inner curved portion 43, which are curved along the outer periphery of the hanger bar HB. This allows the hook portion 4 to be fixed at any angle relative to the hanger bar HB. For example, the container 3 can be positioned above the hanger bar HB as shown by the solid line in FIG. 3(a), the container 3 can be positioned to the side of the hanger bar HB as shown by the solid line in FIG. 3(b), or the container 3 can be positioned diagonally above the hanger bar HB as shown by the two-dot chain line in FIG. 3(b). Therefore, the container can be fixed in a position where it will not be buried in clothing, etc., where it is suitable for chemical diffusion, where it is easy to confirm its location, or where it will not interfere with the insertion and removal of clothing, etc.

[0049] In the chemical volatilizer 1 of this embodiment, the tip of the main hook 21 and the tip of the auxiliary hook 22 are configured to face in opposite directions. With this configuration, even if the main hook 21 (outer curved portion 33) and the auxiliary hook 22 (inner curved portion 43) are extended along the circumferential direction of the hanger bar HB, the tips of the main hook 21 and the auxiliary hook 22 do not butt against each other. Therefore, by forming the main hook 21 and the auxiliary hook 22 to extend along the circumferential direction of the hanger bar HB, the clamping region R (see FIG. 2(b)) in which the hanger bar HB is clamped by the main hook 21 and the auxiliary hook 22 can be easily widened. This allows the clamping force from the main hook 21 and the auxiliary hook 22 to be reliably applied in the radial direction of the hanger bar HB, allowing the hanger bar HB to be more reliably clamped by the main hook 21 and the auxiliary hook 22.

[0050] The above describes the drug volatilization device of the present invention based on one embodiment, but the present invention is not limited to the configuration described in the above embodiment, and the configuration can be changed as appropriate within the scope of its intent. [Example]

[0051] Examples of the chemical volatilization device of the present invention will be described below, but the present invention is not limited to these examples.

[0052] <Rotation test of chemical volatilizer> 4 is an explanatory diagram of a rotation test of the chemical volatilization device 1. A rotation test was carried out to rotate the chemical volatilization device 1 attached to the hanger bar HB, and the force required for rotation was measured.

[0053] [Test method] (1) As shown in FIG. 4, the hook portion 4 is attached to the hanger bar HB, and the container 3 is positioned and fixed vertically above the hanger bar HB. (2) Using a load measuring device (not shown) manufactured by Imada Co., Ltd., the V-shaped metal fitting of the load measuring device is lowered while it is in contact with the second long side portion 12 of the container 3, and the container 3 is pressed downward with the V-shaped metal fitting. When the container 3 starts to rotate, the lowering of the V-shaped metal fitting is stopped, and the numerical value of the pressing force (urging force) of the V-shaped metal fitting when the container 3 starts to rotate is read.

[0054] 5 is an explanatory diagram of a test for attaching and detaching the chemical volatilizing device 1. A test for attaching and detaching the chemical volatilizing device 1 to and from the hanger bar HB was carried out, and the force required for attachment and detachment was measured.

[0055] Example 1 As shown in Figure 4, the chemical volatilizer 1 was attached to a hanger bar HB with an outer diameter of 25 mm so that the container 3 was positioned above the hanger bar HB. The rotation test was performed at a relatively long distance L1 (55 mm) and a relatively short distance L2 (28 mm) from the center line CL passing through the center O of the hanger bar HB and extending vertically to the left side in Figure 4 (the side where the support part 31 of the main hook 21 is located), and at a relatively short distance L3 (17 mm) and a relatively long distance L4 (55 mm) from the center line CL to the right side in Figure 4 (the side where the support part 41 of the auxiliary hook 22 is located). In addition, the force required to attach the hook part 4 to a hanger bar HB with an outer diameter of 25 mm was measured by pushing it downward from above with the container 3 positioned to the side, as shown in Figure 5(a), and to remove it by pulling it upward in the same position, as shown in Figure 5(b). Furthermore, an evaluation test was conducted to assess the ease of adjusting the position of the container 3 relative to the hanger bar HB, and an evaluation test was conducted to assess whether the container 3 would move under its own weight when rotated 90° from the position of the chemical volatilizer 1 shown by the solid line in Figure 3(a) to the position shown by the solid line in Figure 3(b) relative to the hanger bar HB. The test results are shown in Table 1. In Table 1, the evaluation criteria for ease of position adjustment and for fixation are as follows: (Evaluation criteria for ease of position adjustment) A: The force required for position adjustment is less than 5N, making it very easy to adjust. B: The force required for position adjustment is between 5N and 15N and can be easily adjusted. C: The force required to adjust the position is between 15N and 40N, making it a little difficult to adjust. D: The force required to adjust the position is 40N or more, making it difficult to adjust. (Evaluation criteria for fixity) +: Does not move under its own weight. -:Moves using only its own weight.

[0056] [Table 1]

[0057] <Example 2> The above rotation test and the like were carried out on the hanger bar HB having an outer diameter of 32 mm in the same manner as in Example 1. The test results are shown in Table 2.

[0058] [Table 2]

[0059] Example 3 The above rotation test and the like were carried out on the hanger bar HB having an outer diameter of 22 mm in the same manner as in Example 1. The test results are shown in Table 3.

[0060] [Table 3]

[0061] As shown in Tables 1 and 2, when the positions L1 and L4, which are the positions with the greatest horizontal distance from the center O (center line CL) of the hanger bar HB, are biased downward, the minimum biasing force at which the container 3 begins to rotate is 0.59 N. On the other hand, as shown in Table 3, when the position L1, which is the position with the greatest horizontal distance from the center O (center line CL) of the hanger bar HB, is biased downward, the biasing force at which the container 3 begins to rotate is 0.01 N, which may result in the container 3 unintentionally rotating around the hanger bar HB.

[0062] As shown in Table 1, when a hanger bar HB having an outer diameter of 25 mm is urged downward at positions (L1 and L4) 55 mm horizontally away from the center O (center line CL), the average urging force at which rotation begins is 0.59 N and 0.78 N, and the ease of position adjustment is evaluated as "A" and "A." On the other hand, as shown in Table 2, when a hanger bar HB having an outer diameter of 32 mm is urged downward at positions (L1 and L4) 55 mm horizontally away from the center O (center line CL), the average urging force at which rotation begins is 2.62 N and 6.83 N, and the ease of position adjustment is evaluated as "A" and "B." In this way, the drug volatilization device 1 can prevent the container 3 from unintentionally rotating around the hanger bar HB having an outer diameter of 25 to 32 mm, and can easily rotate the container 3 around the hanger bar HB when it is intended to be rotated. As a result, the relative position of the container 3 around the hanger bar HB can be easily adjusted. Furthermore, as shown in Tables 1 and 2, the hook portion 4 of the drug volatilization device 1 could be easily attached and detached from the hanger bar HB without requiring excessive operating force.

[0063] When a pressing force is applied vertically downward to a position 17 mm (distance L3) from the center line CL that passes through the center O of the hanger bar HB, which has an outer diameter of 32 mm, toward the side where the support part 41 of the auxiliary hook 22 is located (the right side in FIG. 4 ) from the center line CL that extends vertically, the force required to adjust the position is 40 N or more (41.52 N), and the evaluation is "D," meaning that adjustment is difficult (see Table 2). The reason for this result is thought to be as follows: That is, because the outer diameter of the hanger bar HB is 32 mm and a pressing force is applied to a position 17 mm (distance L3) from the center line CL toward the side where the support part 41 of the auxiliary hook 22 is located, the position where the pressing force is applied, the support part 41, and a position near the outer periphery of the hanger bar HB, which has an outer diameter of 32 mm and is indicated by a two-dot chain circle in FIG. 4 , are aligned on a straight line indicated by a dashed line labeled "VL" in FIG. 4 that extends vertically. For this reason, it is presumed that the pressing force applied at the position of distance L3 (17 mm) in Figure 4 is unlikely to act as a rotational force to rotate the drug volatilizer 1 around the hanger bar HB, and that the pressing force applied at the position of distance L3 (17 mm) in Figure 4 increases the force with which the hook portion 4 tightens the hanger bar HB, thereby increasing the rotational force itself required to rotate the drug volatilizer 1 around the hanger bar HB.

[0064] Figure 6 is an explanatory diagram of a drug diffusibility test in a wardrobe YD. Figure 6(a) is an explanatory diagram of a drug diffusibility test using the drug volatilization device 1 of the present invention, and Figure 6(b) is an explanatory diagram of a drug diffusibility test using a conventional drug volatilization device 101. Here, the conventional drug volatilization device 101 used is a drug volatilization device with a hook portion that differs from the drug volatilization device 1 of the present invention only in the structure of the hook portion and is structured so that it can be hung on a hanger bar HB in a loose fit state (see, for example, JP 2014-14345 A).

[0065] The wardrobe YD shown in Figures 6(a) and (b) has a capacity of 300 L. In the wardrobe YD, the required number of garments IR were hung on a hanger bar HB installed within the wardrobe YD. The number of garments IR was determined so that the wardrobe YD was not overcrowded and so that the distance between the garments was sufficient to observe the diffusion of the active ingredient of the pesticide to the garments IR. In the wardrobe YD shown in Figure 6(a), filter papers were placed in locations (S1-S6) that took into consideration the diffusion of the active ingredient of the volatile pesticide emitted from the pesticide volatilizer 1 around the garments. In the wardrobe YD shown in Figure 6(b), filter papers were similarly placed in locations (C1-C6) similar to S1-S6. Note that in Figure 6(a), filter papers S4 and S5 are attached to the left side of the garments IR, i.e., the side facing the wall supporting the left end of the hanger bar HB. Similarly, in FIG. 6(b), filter paper C4 and filter paper C5 are attached to the left side of the garment IR in the drawing, that is, the side facing the wall supporting the left end of the hanger bar HB in the drawing.

[0066] As shown in Figure 6(a), one chemical volatilizer 1 of the present invention was installed at the longitudinal center of the hanger bar HB with a container 3 positioned and fixed vertically above the hanger bar HB. On the other hand, as shown in Figure 6(b), one conventional chemical volatilizer 101 was installed at the longitudinal center of the hanger bar HB with a container 103 hanging vertically below the hanger bar HB.

[0067] The amount of the active ingredient (empenthrin) of the volatile drug adhering to the filter paper was then confirmed after 0.5 months, 1 month, and 3 months.

[0068] Table 4 shows the results of the drug diffusion test using the drug volatilization device 1 of the present invention shown in Figure 6(a).

[0069] [Table 4]

[0070] Table 5 shows the results of a drug diffusion test using the conventional drug volatilization device 101 shown in Figure 6(b).

[0071] [Table 5]

[0072] As shown in Table 4, in the drug volatilization device 1 of the present invention, the total amount of the active ingredient of the volatile drug adhered after 0.5 to 3 months was 1354.13 μg (after 0.5 months), 1758.59 μg (after 1 month), and 2332.29 μg (after 3 months). On the other hand, as shown in Table 5, in the conventional drug volatilization device 101, the total amount of the active ingredient of the volatile drug adhered after 0.5 to 3 months was 852.69 μg (after 0.5 months), 1264.17 μg (after 1 month), and 1783.58 μg (after 3 months). Thus, in the drug volatilization device 1 of the present invention, the total amount of the active ingredient of the volatile drug adhered after 0.5 to 3 months was 1.3 to 1.6 times that of the conventional drug volatilization device 101, and good results were obtained. It was also confirmed that the pesticide volatilization device 1 of the present invention has better lethal effects than the conventional pesticide volatilization device 101. Similarly, in spaces with a larger capacity than the wardrobe YD, such as a closet (space of about 1800 L) and a walk-in closet (space of about 12000 L), the difference in effect between the pesticide volatilization device 1 of the present invention and the conventional pesticide volatilization device 101 was observed. [Industrial Applicability]

[0073] The chemical volatilizer of the present invention can be used to volatilize insect repellents and the like in, for example, wardrobes, closets, and the like. [Explanation of symbols]
