Description

The present invention relates to a drug volatilization device.

A known drug volatilization device is one that includes a drug volatilizer that holds a drug that is volatile at room temperature and a container that contains the drug volatilizer. In addition, a drug volatilization device has been proposed that can be used by hanging a hook (hanging member) attached to the top of the container, and that allows the length of the hook to be adjusted (Patent Documents 1 and 2).

JP 2021-97611 A JP 2016-129513 A

However, the drug volatilization device of Patent Document 1 does not allow the length of the band (hanging member) to be adjusted by sliding, making it difficult to adjust the length of the band. Also, in the drug volatilization device of Patent Document 2, the hook is slidably attached to the container, making it easy to adjust the length of the hook. However, if the holding force between the hook and container is increased, the force required to adjust the length of the hook increases, making it difficult to adjust the length. Also, if the force required to adjust the length of the hook is reduced, the holding force of the hook decreases, causing the hook to not be held at the adjusted length and the container to slip off, which is a problem.

The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a drug volatilization device in which the protruding length of the hanging member can be easily adjusted and the container is less likely to slip off.

In order to achieve the above-mentioned object, the drug volatilization device of the present invention is characterized by the following [1] to [5].

The present invention provides a drug volatilization device that allows easy adjustment of the protruding length of the hanging member and prevents the container from slipping off.

The present invention has been briefly described above. The details of the present invention will become clearer by reading the following description of the embodiment of the invention (hereinafter referred to as "embodiment") with reference to the attached drawings.

FIG. 1 is a front view showing one embodiment of a drug volatilization device of the present invention. FIG. 2 is a rear view of the drug volatilization device shown in FIG. FIG. 3 is a partial cross-sectional view taken along line AA of FIG. FIG. 4 is a front view of the hook shown in FIG.

Specific embodiments of the present invention are described below with reference to the drawings.

For ease of explanation, the following definitions are used: "front," "rear," "left," "right," "upper," and "lower," as shown in Figures 1 to 4. The "front-rear direction," "left-right direction," and "upper-lower direction" are mutually orthogonal. The upper-lower direction corresponds to the "sliding direction" of the present invention.

The drug volatilization device 1 according to this embodiment has a long, flat rectangular shape that is long in the vertical direction and thin in the front-to-rear direction in FIG. 1. In the following explanation, a shape that is long in the vertical direction as shown in FIG. 1 will be described, but this shape is merely an example, and the shape of the drug volatilization device 1 is not limited to the shape shown in FIG. 1. For example, the drug volatilization device 1 may have a horizontally long rectangular shape that is long in the left-right direction in FIG. 1, a square shape, another polygonal shape, or a circular or rectangular shape.

As shown in Figures 1 and 2, the drug volatilization device 1 comprises a drug volatilizer 2 that holds a drug that is volatile at room temperature, a container 3 that contains the drug volatilizer, and a hook (hanging member) 4 that is slidably attached to the container 3 and whose protruding length from the container 3 can be adjusted. Note that Figure 1 is a front view of the hook 4 when its protruding length is at its maximum, and Figure 2 is a rear view of the hook 4 when it is submerged in the container 3.

The drug volatilizer 2 has a thin rectangular sheet shape that is long in the vertical direction. Details of the drug volatilizer 2 will be described later.

As shown in Figures 1 and 2, the container 3 has a front housing 5 and a rear housing 6 that are divided into two in the front-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. In addition, the front housing 5 and the rear housing 6 each have a number of openings 51, 61 that expose the drug volatilizer 2 to the outside.

The hook 4 is molded from resin. The hook 4 is slidably attached to the rear housing 6. As shown in FIG. 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.

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

As shown in FIG. 4, the hook 4 is provided in a hook shape so that the upper part can be hooked on 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 FIG. 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 rearward from the hook body 41 and extend in the up-down direction. The pair of guide ribs 42, 42 are arranged side by side in the left-right direction. The right side of the right guide rib 42 (excluding the clamping part 44) of the hook 4 is disposed forward of the right slide rail 62 provided on the rear housing 6. The left side of the left guide rib 42 (excluding the clamping part 44) of the hook 4 is disposed forward of the left slide rail 62 provided on the rear housing 6.

The pair of locking portions 43, 43 are provided protruding in the left-right direction from the hook body 41. The pair of clamping portions 44, 44 are provided protruding in the left-right direction from the hook body 41. As shown in FIG. 3, the pair of locking portions 43, 43 are disposed in front of the pair of slide rails 62, 62, and the pair of clamping portions 44, 44 are disposed in the rear 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 attached so as to slide freely along the pair of slide rails 62, 62.

Next, the pair of locking parts 43, 43 will be described in detail. As shown in FIG. 3, the pair of locking parts 43, 43 are recessed toward the front side and have locking recesses 431 into which the locking protrusions 63 are inserted and locked. The locking recesses 431 lock with one of the locking protrusions 63 arranged in the vertical direction. When the hook 4 is pulled upward, the locking part 43 slides over the locking protrusions 63 it is locked with, climbing over the upper side, and is locked with the adjacent locking protrusion 63 above. This allows the hook 4 to be adjusted to a longer protruding length. Also, when the hook 4 is pushed downward, the locking recesses 431 slide over the locking protrusions 63 it is locked with, climbing over the lower side, and is locked with the adjacent locking protrusion 63 below. This allows the hook 4 to be adjusted to a shorter protruding length.

In addition, in this embodiment, the locking protrusions 63 having high sliding strength with the locking portion 43 and the locking protrusions 63 having low sliding strength with the locking portion 43 are arranged alternately in the vertical direction. That is, in this embodiment, two types of locking protrusions 63 are provided: locking protrusions 63 having high sliding strength and locking protrusions 63 having low sliding strength.

In this embodiment, the locking protrusion 63 with high sliding strength is provided so as to be higher than the locking protrusion 63 with low sliding strength. Also, in this embodiment, the locking protrusion 63 with high sliding strength is provided so 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 the locking protrusion 63 with low sliding strength. In this way, by making the height of the locking protrusion 63 and the inclination angles θ1, θ2 of the upper inclined surface 631 and/or the lower inclined surface 632 of the locking protrusion 63 different, the sliding strength of the locking protrusion 63 can be easily made different. The inclination angle θ1 is preferably less than 90 degrees, and is preferably 80 degrees or less, more preferably 70 degrees or less, from the viewpoint of easily adjusting the protruding length of the hanging member, and is preferably 20 degrees or more, more preferably 30 degrees or more, from the viewpoint of preventing the hanging member from slipping off. In addition, the inclination angle θ2 is preferably less than 90 degrees, and is preferably 85 degrees or less, and more preferably 75 degrees or less, from the viewpoint of easily adjusting the protruding length of the hanging member, and is preferably 30 degrees or more, and more preferably 40 degrees or more, from the viewpoint of preventing the hanging member from slipping off.

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, the material of the drug volatilizer can be, for example, a carrier such as thread (twisted thread, etc.), nonwoven fabric, wood, pulp (paper), inorganic polymeric substances, inorganic porous substances (silicate, silica, zeolite, etc.), and organic polymeric substances (cellulose, polyester, polyethylene, polypropylene, polyvinyl alcohol, etc.). In addition, a carrier that can hold several times its own weight or more, for example, a highly absorbent polymer, cotton, sponge, open-cell foam, etc., can be used.
Furthermore, examples of carriers that efficiently volatilize drugs include nets made of fiber materials such as paper, nonwoven fabric, felt-like fabric, and inorganic fibers. When a net is used, the net generally has a large number of ventilation holes and is excellent in the volatilization effect of the drug. The fiber material used for the net can be manufactured, for example, by knitting short or long fiber yarns using a technique such as lace knitting or stockinette knitting. Examples of yarn materials include natural fibers such as pulp, cotton, wool, hemp, and silk, 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 mixed and used. In particular, from the viewpoint of strength and processability, it is preferable to use polyethylene terephthalate, polypropylene, polybutylene terephthalate, and polyethylene. Furthermore, for example, additives such as antifungal agents, pigments, ultraviolet absorbers, and fragrances may be included in the fiber material.

Regarding the degree of opening of the net using the fiber material, the ratio of the total area of the openings to the total area of the net is preferably 5 to 80%, and more preferably 10 to 50%. Note that the smaller the degree of opening, the lower the volatility of the drug tends to be, and the larger the degree of opening, the shorter the duration of the effect tends to be.

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

Examples of pest control agents include various insecticides, such as organophosphorus, carbamate, and pyrethroid insecticides, repellents, and insect growth regulators. Examples of organophosphorus insecticides include DDVP and diazinon, examples of carbamate insecticides include propoxar, and examples of pyrethroid insecticides include phthalthrin, prallethrin, tefluthrin, transfluthrin, metofluthrin, dimefluthrin, mepafluthrin, profluthrin, empenthrin, and telallethrin. Of these, profluthrin, empenthrin, transfluthrin, and metofluthrin are preferred because of their excellent insecticidal effects. Other pest control agents include plant essential oils, terpenes, and their isomers and derivatives.

Examples of fragrances include essential oils such as lavender oil, musk, tallow oil, 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, aldehyde, citral, citronellal, vanillin, carvone, ketone, menthone, acetophenone, coumarin, cineol, ethyl acetate, octyl acetate, linalyl acetate, butylcyclohexyl acetate, butylcycloheptyl acetate, isopropyl isobutyrate, allyl caproate, ethyl benzoate, methyl cinnamate, and methyl salicylate.

Examples of deodorants 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.

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

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

The drug may contain various additives as necessary, provided that the effects of the present invention are not impaired. Examples of additives include efficacy enhancers, evaporation rate enhancers, and stabilizers. Only one type of additive may be used, or two or more types may be used.

Examples of potency enhancers include peronyl butoxide, N-propyl isome, N-(2-ethylhexyl)bicyclo[2.2.1]hept-5-ene-2,3-dicarboximide (Synepilin 222 (trade name)), N-(2-ethylhexyl)-1-isopropyl-4-methylbicyclo[2.2.2]oct-5-ene-2,3-dicarboximide (Synepilin 500 (trade name)), (2-butoxyethyl)(2-thiocyanoethyl)ether (Riesen 384 (trade name)), octachlorodipropyl ether, isobornyl thiocyanoacetate, and sinetrin.

Examples of the volatilization rate enhancer include phenethyl isothiocyanate.

The method of retaining the drug in the drug volatilizer 2 is not particularly limited. For example, a method of preparing a solution in which the drug is dissolved in a solvent and immersing the above-mentioned net in the solution to impregnate the drug, a method of spraying or dropping the solution or the drug substance onto the net to impregnate the net with the drug, and a method of kneading the drug into the net can be used. Furthermore, if necessary, after the drug is impregnated into the net, the solvent can be removed by drying or the like.

The solvent for preparing the drug solution is not particularly limited, but examples include one or more of the following: water, hydrocarbons such as naphthene, kerosene, and paraffin; alcohols such as glycerin, propylene glycol, dipropylene glycol, hexylene glycol, methanol, isopropanol, 1-octanol, and 1-dodecanol; ketones such as acetone and acetophenone; ethers such as dihexyl ether, diethylene glycol diethyl ether, dipropylene glycol monomethyl ether, dipropylene glycol monobutyl ether, and dipropylene glycol dimethyl ether; esters such as dioctyl adipate, diethyl malonate, and diethyl phthalate; xylene; and silicone oil.

The amount of drug held in the drug volatilizer 2 may be appropriately determined so as to exert the desired effect (volatility and effective period) taking into consideration the type of drug, etc. Furthermore, the drug volatilizer 2 may be configured as a replaceable cartridge. If the drug volatilizer 1 is used for a long period of time and all or most of the drug volatilizes, causing the drug's effect to disappear or decrease, the drug volatilizer 2 can be replaced with a new one to once again exert its excellent effect.

According to the above-mentioned embodiment, two types of locking protrusions 63 are provided: locking protrusions 63 with high sliding strength with the locking portion 43, and locking protrusions 63 with low sliding strength with the locking portion 43. This makes it easy to adjust the protruding length of the hook 4 and makes it difficult for the container 3 to slip off.

Next, the inventors produced the products P1 and P2 of the present invention and the comparative products P3 and P4 described below, and conducted a test to confirm whether the container 3 slipped off and a test to confirm the ease of pulling up the hook 4 described below, thereby confirming the effects of the present invention.

The products P1 and P2 of the present invention and the comparative products P3 and P4 have different shapes of the multiple locking protrusions 63. Tests were conducted on 10 locking protrusions 63 arranged at equal intervals in the vertical direction. For the convenience of the test, the symbols are reassigned so that the bottom locking protrusion in the vertical direction is locking protrusion 63-1 and the top locking protrusion in the vertical direction is locking protrusion 63-10. The bottom locking protrusion 63-1 is locked to the locking portion 43 when the hook 4 is submerged in the container 3 and the protruding length is at its shortest, and the top locking protrusion 63-10 is locked to the locking portion 43 when the hook 4 is at its longest protruding length.

Table 1 below shows the sliding strength of each of the locking protrusions 63-1 to 63-10 of the products P1 and P2 of the present invention and the comparative products P3 and P4. The sliding strength is the force applied when the locking portion 43 slides over the locking protrusions 63-1 to 63-10, and is expressed in N. A value of 1N to 2.5N or less was set as low sliding strength, and a value of 5N to 8.5N was set as high sliding strength. The locking protrusions 63 with low sliding strength are all provided at the same height, the inclination angles θ1 are also provided at the same angle, and the inclination angles θ2 are also provided at the same angle, but the sliding strength is adjusted in the range of 1N to 2.5N. The locking protrusions 63 with high sliding strength are also all provided at the same height, the inclination angles θ1 are also provided at the same angle, and the inclination angles θ2 are also provided at the same angle, but the sliding strength is adjusted in the range of 5N to 8.5N. The sliding strength of the products P1 and P2 of the present invention and the comparison products P3 and P4 used in this test was adjusted by varying only the height of the locking protrusion 63.

In the product P1 of the present invention, the locking protrusions 63-1 and 63-2 with low sliding strength are arranged in this order from bottom to top, followed by the locking protrusions 63-3 to 63-5 with high sliding strength, the locking protrusions 63-6 to 63-8 with low sliding strength, and the locking protrusions 63-9 and 63-10 with high sliding strength (low-high-low-high).

In the product P2 of the present invention, the locking protrusions 63-1 and 63-2 with high sliding strength, the locking protrusions 63-3 to 63-5 with low sliding strength, the locking protrusions 63-6 to 63-7 with high sliding strength, and the locking protrusions 63-8 to 63-10 with low sliding strength are arranged in this order from bottom to top (high-low-high-low).

In the comparative product P3, the sliding strength of all of the engaging protrusions 63-1 to 63-10 is set high (high high high high), whereas in the comparative product P4, the sliding strength of all of the engaging protrusions 63-1 to 63-10 is set low (low low low low).

Next, the slippage test of the container 3 will be described. In the slippage test, the products P1 and P2 of the present invention and the comparative products P3 and P4 were hung from an L-shaped lever doorknob (lever handle type). Assuming entering and exiting a door to which the doorknob was attached, the door was opened 90 degrees, the hand was released, and the door closed automatically. This operation was repeated twice, which constituted one test. After that, it was visually confirmed whether the protruding length of the hook 4 of the products P1 and P2 of the present invention and the comparative products P3 and P4 had increased to cause the container 3 to slip, and this was repeated 10 times. The results are shown in Table 2 below. The cases where the slippage was confirmed visually are marked with "X", and the cases where the slippage was not confirmed visually are marked with "O".

表２に示す結果により、比較品Ｐ４は目視でのずれ落ちが確認され、本発明品Ｐ１，Ｐ２，比較品Ｐ３は目視でのずれ落ちは確認されなかった。今回の試験では、本発明品Ｐ１，Ｐ２においては、摺動強度の高い係止凸部６３と係止部４３とが係止した状態で吊下げられている。しかしながら、摺動強度の弱い係止凸部６３と係止部４３とが係止した状態で吊下げた場合であっても、容器３は多少ずれ落ちるが、摺動強度の高い係止凸部６３と係止部４３とが係止すると、それ以上の容器３のずれ落ちがないため、目視で確認できるほど、容器３のずれ落ちが確認できないものと思われる。

From the results shown in Table 2, the comparative product P4 was confirmed to have slipped off by visual inspection, while the products P1, P2, and the comparative product P3 were not confirmed to have slipped off by visual inspection. In this test, the products P1 and P2 of the present invention were hung in a state in which the locking protrusion 63 with high sliding strength and the locking part 43 were engaged. However, even when the container 3 was hung in a state in which the locking protrusion 63 with low sliding strength and the locking part 43 were engaged, the container 3 slipped off to some extent, but when the locking protrusion 63 with high sliding strength and the locking part 43 were engaged, the container 3 did not slip off any further, so it is thought that the container 3 slipped off to a degree that could be confirmed by visual inspection.

Next, a test to confirm the ease of pulling up the hook 4 will be described. In the test to confirm the ease of pulling up, 10 subjects A to J (2 men and 8 women) were asked to pull up the hook 4 of the products of the present invention P1 and P2 and the comparison products P3 and P4 with the hook 4 submerged in the container 3, and to evaluate it on a 10-point scale using the evaluation criteria described below. The results are shown in Table 3 below. Note that the lower the value, the easier it is to pull up, and the higher the value, the more difficult it is to pull up. A value of "6" or higher was considered difficult to pull up, and a value of "5" or lower was considered easy to pull up.

From the results shown in Table 3, all subjects found comparison product P3 difficult to pull up, while all subjects found products P1, P2, and comparison product P4 easy to pull up. Furthermore, almost all subjects answered that product P2 of the present invention was easier to pull up than product P1 of the present invention. This is likely because product P2 of the present invention requires a large force when initially pulling up hook 4, but the large force is pulled vigorously, sliding over the locking protrusion 63, which has low sliding strength, making it seem easier to pull up. On the other hand, product P1 of the present invention requires a small force when initially pulling up hook 4, so the locking protrusion 63, which has high sliding strength, slides without gaining momentum, making it seem difficult to pull up.

The above slip-off test and ease-of-pull-up confirmation test showed that with comparison product P3, the container 3 is less likely to slip off, but the hook 4 is harder to pull up, and with comparison product P4, the hook 4 is easier to pull up, but the container 3 is easier to fall off. In contrast, it was found that with products P1 and P2 of the present invention, the hook 4 is easier to pull up (the protruding length of the hook 4 can be easily adjusted) and the container 3 is less likely to slip off.

According to the above-described embodiment, two or more types of locking protrusions 63 with different heights are provided. This makes it easy to vary the sliding strength of the multiple locking protrusions 63.

According to the above-described embodiment, two or more types of locking protrusions 63 with different inclination angles θ1 and θ2 are provided. This makes it easy to differentiate the sliding strength of the multiple locking protrusions 63.

In addition, according to the embodiment described above, the locking protrusions 63 with high sliding strength and the locking protrusions 64 with low sliding strength are provided alternately. As a result, even if the locking portion 43 is suspended while being locked by the locking protrusions 63 with low sliding strength due to its own weight or the impact generated when opening and closing the door, the container 3 is unlikely to slip off any further once it is locked by the locking protrusions 63 with high sliding strength.

In addition, according to the embodiment described above, the product P2 of the present invention has a high sliding strength of the locking protrusion 63 that is locked to 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 a low sliding strength of the locking protrusion 63 that is locked to the locking portion 43 when the protruding length of the hook 4 is at its shortest.

The present invention is not limited to the above-described embodiment, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, location, etc. of each component in the above-described embodiment are arbitrary as long as they can achieve the present invention, and are not limited.

In the products P1 and P2 of the present invention used in the above-mentioned tests, the height of the locking protrusion 63 was made different to make the sliding strength different, but this is not limited to this. As a means for making the sliding strength different, the inclination angle θ1 of the locking protrusion 63 may be made different as explained in the above-mentioned embodiment, or the inclination angle θ2 may be made different. In other words, one or more of the height, inclination angles θ1, θ2 of the locking protrusion 63 may be made different.

In the above-described embodiment, multiple locking protrusions 63 are provided on the container 3, and the locking portion 43 is provided on the hook 4, but this is not limited to the above.
