Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the drug volatilization device of Patent Document 1, since the length of the band (hanging member) cannot be adjusted by sliding, it is not easy to adjust the length of the band. Further, in the drug volatilization device of Patent Document 2, the hook is slidably attached to the container, and the length of the hook can be easily adjusted. However, when the holding force between the hook and the container is increased, the force required for adjusting the length of the hook becomes large, making it difficult to adjust the length. Also, when the force required for adjusting the length of the hook is reduced, the holding force of the hook becomes low, and there is a problem that the container cannot be held at the adjusted length and the container slips off.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a drug volatilization device in which the protruding length of the hanging member can be easily adjusted and the container is difficult to slip off. [Means for solving the problem]

[0013] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by referring to the attached drawings and reading through the embodiments for carrying out the invention described below (hereinafter referred to as "embodiments"). [Brief explanation of the drawing]

[0014] [Figure 1] FIG. 1 is a front view showing an embodiment of the chemical agent volatilizer of the present invention. [Figure 2] FIG. 2 is a rear view of the chemical agent volatilizer shown in FIG. 1. [Figure 3] FIG. 3 is a partial cross-sectional view taken along line A-A of FIG. 1. [Figure 4] FIG. 4 is a front view of the hook shown in FIG. 1.

Embodiments for Carrying out the Invention

[0015] Specific embodiments of the present invention will be described below with reference to the respective figures.

[0016] Hereinafter, for convenience of explanation, as shown in FIGS. 1 to 4, “front”, “rear”, “left”, “right”, “upper” and “lower” are defined. The “front-rear direction”, “left-right direction” and “upper-lower direction” are orthogonal to each other. Further, the upper-lower direction corresponds to the “slide direction” of the present invention.

[0017] The chemical agent volatilizer 1 according to the present embodiment is vertically long in the up-down direction in FIG. 1 and has a vertically long flat rectangular shape that is thin in the front-rear direction. In the following description, as shown in FIG. 1, the shape that is long in the up-down direction will be described, but this shape is merely an example, and the shape of the chemical agent volatilizer 1 is not limited to the shape shown in FIG. 1. For example, the chemical agent volatilizer 1 may have a horizontally long rectangular shape that is long in the left-right direction in FIG. 1, may have a square shape, may have other polygonal shapes, or may have a circular or rectangular shape.

[0018] As shown in FIGS. 1 and 2, the chemical agent volatilizer 1 includes a chemical agent volatilizer body 2 that holds a room-temperature volatile chemical agent, a container 3 that houses the chemical agent volatilizer body, and a hook (hanging member) 4 that is slidably attached to the container 3 and the protruding length from the container 3 can be adjusted. Note that FIG. 1 is a front view of the state where the protruding length of the hook 4 is maximum, and FIG. 2 is a rear view of the state where the hook 长 4 is submerged in the container 3.

[0019] The above-mentioned volatile chemical material 2 has a long, rectangular, thin sheet shape. Details of the volatile chemical material 2 will be described later.

[0020] As shown in Figures 1 and 2, the container 3 has a front housing 5 and a rear housing 6, which are divided into two parts in the front-to-rear direction. The front housing 5 and the rear housing 6 are molded from resin. The front housing 5 and the rear housing 6 hold the drug volatilizer 2 between them. The front housing 5 and the rear housing 6 also each have a plurality of openings 51, 61 that expose the drug volatilizer 2 to the outside.

[0021] The hook 4 is molded from resin. The hook 4 is slidably attached to the rear housing 6. As shown in Figure 2, the rear housing 6 has a pair of slide rails 62, 62 for slidably attaching the hook 4. The pair of slide rails 62, 62 are erected from the left and right ends of the rear housing 6 toward the center in the left-right direction. The pair of slide rails 62, 62 are provided along the vertical direction, and the hook 4 slides up and down along the pair of slide rails 62, 62.

[0022] As shown in Figure 3, the rear housing 6 has a plurality of locking protrusions (first locking parts) 63 arranged in a vertical direction. The plurality of locking protrusions 63 are provided projecting forward from a pair of slide rails 62, 62. The locking protrusions 63 have an upper inclined surface 631 and a lower inclined surface 632, the height of which decreases as you move away from the center in the vertical direction. In this embodiment, the inclination angle θ1 of the upper inclined surface 631 is smaller than the inclination angle θ2. As a result, when increasing the protruding length of the hook 4, the locking part 43, described later, rides over the lower inclined surface 632 with a large inclination angle θ2, and then rides over the upper inclined surface 631 with a small inclination angle θ1, so that it can be locked to the next higher locking protrusion 63 without applying force. Also, when shortening the protruding length of the hook 4, if the inclination angle θ1 is small, the hook 4 can be pushed down with a small force.

[0023] As shown in Figure 4, the hook 4 is provided in a hook shape so that its upper part can be hooked onto a doorknob or the like. The hook 4 has a hook body 41 provided in a hook shape, a pair of guide ribs 42, 42 (see Figure 2), a pair of locking parts 43, 43 (second locking parts), and a pair of clamping parts 44, 44. The pair of guide ribs 42, 42 protrude to the rear from the hook body 41 and extend in the vertical direction. The pair of guide ribs 42, 42 are provided side by side in the left-right direction. In the hook 4, the right side of the right guide rib 42 (excluding the clamping part 44) is positioned in front of the right slide rail 62 provided on the rear housing 6. In the hook 4, the left side of the left guide rib 42 (excluding the clamping part 44) is positioned in front of the left slide rail 62 provided on the rear housing 6.

[0024] A pair of locking portions 43, 43 are provided protruding from the hook body 41 in the left-right direction. A pair of clamping portions 44, 44 are provided protruding from the hook body 41 in the left-right direction. As shown in Figure 3, the pair of locking portions 43, 43 are positioned on the front side of the pair of slide rails 62, 62, and the pair of clamping portions 44, 44 are positioned on the rear side of the slide rails 62, 62. In other words, the pair of locking portions 43, 43 and the pair of clamping portions 44, 44 clamp the slide rails 62, 62 in the front-rear direction, thereby allowing the hook 4 to be slidably attached along the pair of slide rails 62, 62.

[0025] Next, the details of the pair of locking parts 43, 43 will be described. As shown in Figure 3, the pair of locking parts 43, 43 are recessed toward the front and have locking recesses 431 into which locking projections 63 are inserted and locked. The locking recess 431 locks with one of the multiple locking projections 63 arranged in the vertical direction. When the hook 4 is pulled upward, the locking part 43 slides over the locked locking projection 63 and locks with the adjacent locking projection 63 above it. This allows the protruding length of the hook 4 to be adjusted to be longer. Also, when the hook 4 is pushed downward, the locking recess 431 slides over the locked locking projection 63 and locks with the adjacent locking projection 63 below it. This allows the protruding length of the hook 4 to be adjusted to be shorter.

[0026] Furthermore, in this embodiment, locking projections 63 with high sliding strength against the locking portion 43 and locking projections 63 with low sliding strength against the locking portion 43 are arranged alternately along the vertical direction. In other words, in this embodiment, two types of locking projections 63 are provided: locking projections 63 with high sliding strength and locking projections 63 with low sliding strength.

[0027] In this embodiment, the locking projection 63 with high sliding strength is provided to be taller than the locking projection 63 with low sliding strength. Also in this embodiment, the locking projection 63 with high sliding strength is provided to be provided such that the inclination angle θ1 of the upper inclined surface 631 and / or the inclination angle θ2 of the lower inclined surface 632 are larger than that of the locking projection 63 with low sliding strength. By making the height of the locking projection 63 and the inclination angles θ1 and θ2 of the upper inclined surface 631 and / or lower inclined surface 632 of the locking projection 63 different in this way, the sliding strength of the locking projection 63 can be easily made different. Regarding the inclination angle θ1, it is preferably less than 90 degrees, preferably 80 degrees or less, more preferably 70 degrees or less from the viewpoint of easily adjusting the protruding length of the suspension member, and preferably 20 degrees or more, and more preferably 30 degrees or more from the viewpoint of preventing the suspension member from slipping down. Furthermore, regarding the inclination angle θ2, it is preferable that it be less than 90 degrees, preferably 85 degrees or less, more preferably 75 degrees or less, from the viewpoint of easily adjusting the protruding length of the suspension member, and preferably 30 degrees or more, more preferably 40 degrees or more, from the viewpoint of preventing the suspension member from slipping down.

[0028] Next, the drug volatilizer 2 will be described. The drug volatilizer 2 that holds the drug is not particularly limited as long as it can hold the drug. Specifically, examples of materials for the drug volatilizer include carriers such as yarn (twisted yarn, etc.), nonwoven fabric, wood, pulp (paper), inorganic polymers, inorganic porous materials (silicates, silica, zeolite, etc.), and organic polymers (cellulose, polyester, polyethylene, polypropylene, polyvinyl alcohol, etc.). In addition, carriers that can hold several times their own weight or more may be used, such as superabsorbent polymers, cotton, sponges, and open-cell foams. Furthermore, examples of carriers that efficiently volatilize the drug include nets made of fibrous materials such as paper, nonwoven fabrics, felt-like fabrics, and inorganic fibers. When using a net, the net generally has a large number of ventilation holes and is excellent in volatilizing the drug. The fibrous material used for the net can be manufactured, for example, by knitting short or long fibers using techniques such as lace knitting or jersey knitting. Examples of yarn materials include natural fibers such as pulp, cotton, wool, hemp, and silk, as well as polypropylene, polyethylene, polyamide, polyethylene terephthalate, polybutylene terephthalate, polysulfone, rayon, methacrylic acid resin, and biodegradable resins (e.g., polyglycolic acid, polylactic acid, and poly(β-hydroxybutyric acid)). One or more of these materials may be used in mixtures. In particular, from the viewpoint of strength and processability, it is preferable to use polyethylene terephthalate, polypropylene, polybutylene terephthalate, and polyethylene. Furthermore, the fiber material may contain additives such as antifungal agents, dyes, UV absorbers, and fragrances.

[0029] Regarding the degree of opening in a net made of fibrous material, the ratio of the total area of ​​openings to the total area of ​​the net is preferably 5-80%, and more preferably 10-50%. Note that the smaller the degree of opening, the lower the volatility of the chemical tends to be, and the larger the degree of opening, the shorter the duration of the effect tends to be.

[0030] The chemical held by the chemical volatilizer 2 is a chemical that can volatilize at room temperature, and can be appropriately selected from various chemicals such as various pest control agents (insecticides and repellents, etc.), fragrances, deodorizers / odor removers, fungicides, and fungicides, depending on the purpose, and is not particularly limited. One type of chemical may be used, or two or more types may be used.

Of these, profluthrin, empenthrin, transfluthrin, and metofluthrin are preferred for their excellent insecticidal effects. Other pest control agents include plant essential oils, terpenes, and their isomers and derivatives.

[0032] Examples of fragrances include essential oils such as lavender oil, musk, limonol, abies oil, citronella oil, eucalyptus oil, fennel oil, garlic oil, ginger oil, grapefruit oil, lemon oil, lemongrass oil, nutmeg oil, peppermint oil, orange oil, turpentine oil, and sage oil; and fragrances such as pinene, limonene, linalool, geraniol, citronellal, borneol, benzyl alcohol, anise alcohol, anethole, eugenol, aldehydes, citral, citronellal, vanillin, carvone, ketone, menthone, acetophenone, coumarin, cineole, ethyl acetate, octyl acetate, linalyl acetate, butylcyclohexyl acetate, butylcycloheptyl acetate, isopropyl isobutyrate, allyl caproate, ethyl benzoate, methyl cinnamate, and methyl salicylate.

[0033] Examples of deodorizing and odor-preventing agents include benzyl acetate, benzyl propionate, amyl cinnamic aldehyde, anisic aldehyde, diphenyl oxide, methyl benzoate, ethyl benzoate, methyl phenylacetate, ethyl phenylacetate, neolin, safrole, citronella oil, and lemongrass oil.

[0034] Examples of disinfectants include isopropylmethylphenol, PCMX (p-chloro-m-xylenol), AIT (allyl isothiocyanate), hinokitiol, and stabilized chlorine dioxide.

[0035] Examples of antifungal agents include sodium pyrithione, zinc pyrithione, IPBC (3-iodo-2-propynylbutylcarbamate), thiabendazole, imazalil, orthophenylphenol, cetylpyridinium chloride, benzalkonium chloride, and benzethonium chloride.

[0036] The drug may contain various additives as needed, provided that they do not impair the effects of the present invention. Examples of additives include efficacy enhancers, volatilization rate improvers, and stabilizers. Only one type of additive may be used, or two or more types may be used.

[0037] Examples of potency enhancers include peronyl butoxide, N-propyl isome, N-(2-ethylhexyl)bicyclo[2.2.1]hepta-5-en-2,3-dicarboxide (Sinepirin 222 (trade name)), N-(2-ethylhexyl)-1-isopropyl-4-methylbicyclo[2.2.2]octa-5-en-2,3-dicarboxide (Sinepirin 500 (trade name)), (2-butoxyethyl)(2-thiocyanoethyl) ether (Liesen 384 (trade name)), octachlorodipropyl ether, isobornyl thiocyanoacetate, and synetrin.

[0039] The method for retaining the drug in the drug volatilizer 2 is not particularly limited. For example, one method may be to prepare a solution by dissolving the drug in a solvent and immerse the aforementioned net in the solution to impregnate it with the drug; to spray or drop the solution or the raw drug onto the net to impregnate the net with the drug; or to knead the drug into the net. Furthermore, if necessary, the solvent may be removed by drying or other means after impregnating the net with the drug.

[0040] There are no particular restrictions on the solvent used to prepare the drug solution, but examples include one or more of the following: water, naphthenes, kerosene, paraffin and other hydrocarbons, alcohols such as glycerin, propylene glycol, dipropylene glycol, hexylene glycol, methanol, isopropanol, 1-octanol, 1-dodecanol, ketones such as acetone, acetophenone, ethers such as dihexyl ether, diethylene glycol diethyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monobutyl ether, dipropylene glycol dimethyl ether, esters such as dioctyl adipate, diethyl malonate, diethyl phthalate, xylene, and silicone oil.

[0041] The amount of pesticide held in the pesticide volatilizer 2 should be appropriately determined considering the type of pesticide, etc., to achieve the desired effect (volatility and duration of effectiveness). Furthermore, the pesticide volatilizer 2 may be configured as a replaceable cartridge type. If the pesticide volatilizer 1 is used for a long period and all or almost all of the pesticide volatilizes, resulting in the loss or reduction of the pesticide's effectiveness, the pesticide volatilizer 2 can be replaced with a new one to restore its excellent effectiveness.

[0042] According to the embodiment described above, two types of locking protrusions 63 are provided: a locking protrusion 63 with high sliding strength with the locking portion 43, and a locking protrusion 63 with low sliding strength with the locking portion 43. This makes it easy to adjust the protruding length of the hook 4 and prevents the container 3 from slipping off.

[0043] Next, the inventors manufactured the inventive products P1 and P2, and comparative products P3 and P4, as described later, and conducted a test to confirm the slippage of the container 3 and the ease of lifting the hook 4, as described later, to confirm the effects of the present invention.

[0044] Products P1 and P2 of the present invention, and comparative products P3 and P4, each have different shapes for their multiple locking protrusions 63. Now, we have tested 10 locking protrusions 63 that are arranged at equal intervals in the vertical direction. For the convenience of the test, we will renumber the protrusions so that the lowest one in the vertical direction is designated as locking protrusion 63-1 and the highest one as locking protrusion 63-10, and explain them accordingly. The lowest locking protrusion 63-1 is locked to the locking part 43 when the hook 4 is submerged in the container 3 and its protruding length is at its shortest, and the uppermost locking protrusion 63-10 is locked to the locking part 43 when the protruding length of the hook 4 is at its longest.

[0045] Table 1 below shows the sliding strength of the locking projections 63-1 to 63-10 of the present invention products P1 and P2, and comparative products P3 and P4. Sliding strength is the force applied when the locking part 43 slides over the locking projections 63-1 to 63-10, and the unit is N. A sliding strength of 1N to 2.5N or less is defined as low sliding strength, and a sliding strength of 5N to 8.5N is defined as high sliding strength. All locking projections 63 with low sliding strength are provided at the same height, with the same inclination angle θ1 and θ2, but the sliding strength is adjusted to the range of 1N to 2.5N. Similarly, all locking projections 63 with high sliding strength are provided at the same height, with the same inclination angle θ1 and θ2, but the sliding strength is adjusted to the range of 5N to 8.5N. The products P1 and P2 of the present invention and the comparative products P3 and P4 used in this test had their sliding strength adjusted by varying only the height of the locking projection 63.

[0046] [Table 1]

[0047] Product P1 of the present invention has locking protrusions 63-1 and 63-2 with low sliding strength, locking protrusions 63-3 to 63-5 with high sliding strength, locking protrusions 63-6 to 63-8 with low sliding strength, and locking protrusions 63-9 and 63-10 with high sliding strength arranged from bottom to top (low, high, low, high).

[0048] Product P2 of the present invention has locking protrusions 63-1 and 63-2 with high sliding strength, locking protrusions 63-3 to 63-5 with low sliding strength, locking protrusions 63-6 to 63-7 with high sliding strength, and locking protrusions 63-8 to 63-10 with low sliding strength arranged in the order from bottom to top (high-low-high-low).

[0049] In comparative product P3, the sliding strength of all locking protrusions 63-1 to 63-10 is set to be high (high high high high), while in comparative product P4, the sliding strength of all locking protrusions 63-1 to 63-10 is set to be low (low low low low).

[0050] Next, we will describe the slip-down test of container 3. In the slip-down test, the inventive products P1 and P2, and comparative products P3 and P4 were suspended from an L-shaped lever door knob (lever handle type). To simulate entering and exiting a door with a door knob attached, the door was opened 90 degrees, then released, and the door was allowed to close automatically. This operation was repeated twice, and this constituted one test. After that, it was visually checked whether the protruding length of the hook 4 of the inventive products P1 and P2 and comparative products P3 and P4 had increased and whether container 3 had slipped down. This was done 10 times. The results are shown in Table 2 below. Note that "×" indicates that slip-down was confirmed visually, and "○" indicates that slip-down was not confirmed visually.

[0051] [Table 2] As shown in Table 2, comparative product P4 was observed to slip down visually, while no slippage was observed visually in the inventive products P1, P2, and comparative product P3. In this test, in the inventive products P1 and P2, the container 3 was suspended with the locking projection 63 and locking part 43, which have high sliding strength, locked together. However, even when the container 3 was suspended with the locking projection 63 and locking part 43, which have weak sliding strength, locked together, the container 3 would slip down slightly. However, when the locking projection 63 and locking part 43, which have high sliding strength, are locked together, the container 3 does not slip down any further, so it is thought that the slippage of the container 3 is not visible.

[0052] Next, we will explain the test to confirm the ease of lifting hook 4. In the test to confirm the ease of lifting, 10 subjects (2 men and 8 women), designated A to J, were asked to lift the hook 4 of the present invention products P1 and P2, and comparative products P3 and P4, while the hook 4 was submerged in container 3, and evaluated it on a 10-point scale according to the evaluation criteria described later. The results are shown in Table 3 below. A lower number indicates that it was easier to lift, and a higher number indicates that it was more difficult. Furthermore, a score of "6" or higher was considered difficult to lift, and a score of "5" or lower was considered easy to lift.

[0053] [Table 3]

[0054] As shown in Table 3, all participants found comparative product P3 difficult to pull up, while all participants found the inventive products P1, P2, and comparative product P4 easy to pull up. Furthermore, almost all participants found the hook 4 easier to pull up with inventive product P2 than with inventive product P1. This is likely because inventive product P2 requires a large force to initially pull up the hook 4, but the force and momentum of the pull cause the locking projection 63, which has low sliding strength, to slide, making it feel easier to pull up for the participants. On the other hand, inventive product P1 requires a small force to initially pull up the hook 4, so the locking projection 63, which has high sliding strength, slides without gaining momentum, making it feel more difficult to pull up for the participants.

[0055] Based on the above slippage test and ease of lifting test, comparative product P3 showed that while the container 3 was less likely to slip off, the hook 4 was difficult to lift. Comparative product P4 showed that while the hook 4 was easy to lift, the container 3 was prone to falling. In contrast, it was found that the present invention products P1 and P2 made it easy to lift the hook 4 (the protruding length of the hook 4 could be easily adjusted) and prevented the container 3 from slipping off.

[0056] According to the embodiment described above, two or more types of locking projections 63 with different heights are provided. This makes it easy to make the sliding strength of the multiple locking projections 63 different.

[0057] According to the embodiment described above, two or more types of locking projections 63 with different inclination angles θ1 and θ2 are provided. This makes it easy to vary the sliding strength of multiple locking projections 63.

[0058] Furthermore, according to the embodiment described above, locking projections 63 with high sliding strength and locking projections 64 with low sliding strength are provided alternately. As a result, the locking portion 43 is suspended while locked by the locking projections 63 with low sliding strength, and even if the locking projections 63 with low sliding strength are pushed over by the locking projections 63 with low sliding strength due to its own weight or the impact generated when opening and closing the door, the container 3 is less likely to slip down further once it is locked by the locking projections 63 with high sliding strength.

[0059] Furthermore, according to the embodiments described above, the product P2 of the present invention has high sliding strength of the locking projection 63 that engages with the locking portion 43 when the protruding length of the hook 4 is at its shortest. As a result, as shown in Table 3, the product P2 of the present invention feels easier to pull up than the product P1 of the present invention, which has low sliding strength of the locking projection 63 that engages with the locking portion 43 when the protruding length of the hook 4 is at its shortest.

[0060] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention.

[0061] In the invention products P1 and P2 used in the above-described test, the sliding strength was varied by varying the height of the locking projection 63, but this is not the only way. As a means of varying the sliding strength, the inclination angle θ1 of the locking projection 63 may be varied, or the inclination angle θ2 may be varied, as described in the above-described embodiment. In other words, one or more of the height of the locking projection 63 or the inclination angles θ1 and θ2 may be varied.

[0062] In the embodiment described above, multiple locking protrusions 63 were provided on the container 3 and the locking portion 43 was provided on the hook 4, but this is not the only configuration. Multiple locking protrusions 63 may be provided on the hook 4 and the locking portion 43 on the container 3.

[0063] In the embodiment described above, two types of locking protrusions 63 with different sliding strengths were provided, but this is not the only option. Three or more types of locking protrusions 63 with different sliding strengths may be provided.

[0064] In the tests described above, the products P1 and P2 of the present invention had two or more locking protrusions 63 with high sliding strength and two or more locking protrusions 63 with low sliding strength arranged alternately along the vertical direction, but this is not the only arrangement. Locking protrusions 63 with high sliding strength and locking protrusions 63 with low sliding strength may be arranged alternately one by one. [Explanation of Symbols]
