Description

Technical Field

[0001] The present invention relates to a hanging hook used when hanging an article and a chemical diffuser provided with the same.

Background Art

[0002] For example, Patent Document 1 discloses that an insect repellent chemical diffuser is used by hanging it on an outdoor pole or the like. The insect repellent chemical diffuser of Patent Document 1 is formed by housing an impregnated sheet impregnated with an insect repellent chemical in a plate-shaped container, and a hook for removably rotating the container is attached to the upper part of the container.

[0003] In addition, Patent Document 2 discloses a clothes hanger. The hook of this hanger has a rotating arm having an upper arm and a lower arm rotatably connected to a hook body via a support shaft. By rotating the rotating arm, a pole can be sandwiched between the hook body and the rotating arm.

[0004] In addition, Patent Document 3 discloses a hook that is hung on a drying pole. This hook includes a hook body formed with a notch for passing a pole, a retaining member swingably supported on a shaft provided below the notch of the hook body between a state of closing the notch and a state of opening the notch, and a spring for biasing the retaining member so as to close the notch.

Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, by suspending an insect repellent agent diffuser such as that of Patent Document 1 outdoors on a pole or the like, the agent can be diffused over a wide area by the wind, and the efficacy of the agent can be enhanced. However, as a result of investigations by the inventors of the present application, it has been found that when the agent diffuser of Patent Document 1 is suspended on a drying pole, there is a problem that when the wind hits, the agent diffuser moves in the longitudinal direction of the drying pole due to the wind. In particular, since clothes or the like are often hung on the drying pole, there is a need to prevent the agent diffuser from coming into contact with the clothes or the like. Further, when it is suspended on a pole other than the drying pole, there is a risk of moving to the end of the pole and falling due to the wind.

[0007] Therefore, it is conceivable to sandwich the pole with a hook as disclosed in Patent Documents 2 and 3 and fix the hook to the pole. However, in Patent Document 2, a rotating arm, a support shaft, and a hook body are required as parts, and in Patent Document 3, a hook body, a retaining member, and a spring are required as parts, resulting in a large number of parts. When the number of parts is large, the assembly man-hours increase, leading to higher costs, and it is necessary to devise so as not to disassemble during use, which may lead to further higher costs.

[0008] The present invention has been made in view of such points, and an object thereof is to achieve cost reduction by configuring a hanging hook that can be fixed to a rod-shaped member with a small number of parts.

Means for Solving the Problems

[0009] In order to achieve the above object, in the first disclosure, a hanging hook for hanging an article on a rod-shaped member extending in a substantially horizontal direction is assumed. The hanging hook includes a tightening portion that surrounds the rod-shaped member in the circumferential direction and is formed such that a part of the circumferential direction is discontinuous and can be opened. Further, on one side in the circumferential direction of the tightening portion, a plurality of engaging portions are formed so as to be arranged in the circumferential direction, and on the other side in the circumferential direction of the tightening portion, an engaged portion that engages with the engaging portion is formed.

[0010] According to this configuration, since a part of the circumferential direction of the tightening part is discontinuous, by deforming the tightening part so that the discontinuous part is opened, it becomes possible to insert the rod-shaped member into the inside of the tightening part from the opened part of the tightening part. After that, when the engaging part is engaged with the engaged part, the tightening part closes and the rod-shaped member is tightened. At this time, since a plurality of engaging parts are arranged in the circumferential direction, by changing the engaging part with which the engaged part is engaged, the circumferential length of the tightening part can be surely tightened in accordance with the circumferential length of the rod-shaped member. Therefore, without combining a plurality of parts as in the conventional example, for example, a suspension hook formed as an integrally molded product of a resin material can be fixed to the rod-shaped member, so that the cost can be reduced.

[0011] In the second disclosure, on the other side in the circumferential direction of the tightening part, a plurality of the engaged parts are formed so as to be arranged in the circumferential direction.

[0012] According to this configuration, since a plurality of engaging parts and a plurality of engaged parts can be engaged, it is possible to prevent the discontinuous part of the tightening part from unexpectedly opening.

[0013] In the third disclosure, one side in the circumferential direction of the tightening part is formed so as to be arranged so as to overlap the outer surface of the other side in the circumferential direction of the tightening part, the engaging part is composed of teeth protruding radially inward from the inner surface of one side in the circumferential direction of the tightening part, the engaged part is formed on the outer surface of the other side in the circumferential direction of the tightening part, and is composed of a groove into which the teeth are fitted.

[0014] According to this configuration, by fitting the teeth into the grooves, they can be firmly engaged. Also, if a plurality of teeth are provided, the circumferential length of the tightening part can be easily changed by fitting any of the teeth into the groove.

[0015] In the fourth disclosure, the clamping portion is configured to be openable in the horizontal direction. That is, for example, when the diameter of the rod-shaped member is large and the circumferential length of the clamping portion is insufficient, it is conceivable that the engaged portion cannot be engaged with the engaging portion. In this case, if the clamping portion is opened in the horizontal direction and then the rod-shaped member is inserted inside the clamping portion, the upper portion of the clamping portion can be hooked on the rod-shaped member, preventing the article from falling off.

[0016] In the fifth disclosure, a first finger contact portion and a second finger contact portion for applying a finger when tightening are provided on one side and the other side in the circumferential direction of the clamping portion, respectively.

[0017] According to this configuration, by applying a force in a direction approaching each other by placing fingers on the first finger contact portion and the second finger contact portion respectively, the teeth can be engaged with the grooves.

[0018] In the sixth disclosure, a concave portion that is recessed upward is formed on the inner surface above the clamping portion. That is, for example, it is assumed that a hanging hook is hung on a string thinner than the rod-shaped member. In this case, the hanging hook can be hooked on the string by putting the string into the concave portion.

[0019] In the seventh disclosure, the width of the concave portion becomes narrower as it goes upward, so that it is difficult for the string or the like to come off when hooked on the concave portion.

[0020] In the eighth disclosure, it is possible to assume a drug diffuser including a drug holding body that holds an evaporating drug, a container that houses the drug holding body, a drug diffuser main body configured to diffuse the drug to the outside through an opening for drug diffusion formed in the container, and a hanging member for suspending the drug diffuser main body so as to be suspendable from a rod-shaped member extending in a substantially horizontal direction. And the said suspension member is provided with the clamping part which surrounds the said rod-shaped member in the circumferential direction and is formed so that a part of the circumferential direction may be discontinuous and openable. Further, on one side in the circumferential direction of the clamping portion, a plurality of engaging portions are formed so as to be arranged in the circumferential direction, and on the other side in the circumferential direction of the clamping portion, an engaged portion that engages with the engaging portion is formed.

[0021] According to this configuration, the drug diffuser main body can be suspended from the rod-shaped member by a suspension member having the same operational effects as those of the first disclosure.

Advantages of the Invention

[0022] As described above, since the suspension hook that can be fixed to the rod-shaped member can be configured with a small number of parts, the cost of the suspension hook can be reduced.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. It should be noted that the following description of the preferred embodiments is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses.

[0025] FIG. 1 shows a drug diffuser 1 according to an embodiment of the present invention. The drug diffuser 1 includes a drug diffuser main body 10 and a suspension member 40 for suspending the drug diffuser main body 10. The drug diffuser main body 10 includes a drug holding body 11 that holds an evaporating drug and a container 20 that houses the drug holding body 11, and is configured to diffuse the drug to the outside of the container 20 through an opening 21a and an opening 22a (shown in FIG. 3) for drug diffusion formed in the container 20. Note that the suspension member 40 is detachably provided with respect to the drug diffuser main body 10.

[0026] In the description of this embodiment, the front side of the drug diffuser 1 in the use state is defined as the front side, the back side is defined as the rear side, the left side when the drug diffuser 1 in the use state is viewed from the front is defined as the left side of the drug diffuser 1, and the right side is defined as the right side of the drug diffuser 1. Therefore, the width direction of the drug diffuser 1 is the left-right direction. This definition of the direction is only for convenience of explanation, and either side may be the right side during actual use. Also, regarding the front-rear direction, either side may face forward during use. Further, since the container 20 of this embodiment rotates around a vertical line, the front and rear, and the left and right may be interchanged during use.

[0027] The drug diffuser 1 is preferably used where there is wind blowing, but it can also be used with almost no wind. When used where there is wind blowing, it is preferable to arrange the drug diffuser 1 so that the wind hits from the front side of the drug diffuser 1. In this embodiment, the front side of the drug diffuser 1 is defined as the upstream side in the air flow direction, and the rear side of the drug diffuser 1 is defined as the downstream side in the air flow direction. Since the wind direction is not always constant under natural conditions, the wind may hit from the front side of the drug diffuser 1, or may hit from the rear side or the left and right sides. Since natural wind hits, its strength may be strong or weak.

[0028] (Configuration of the drug holding body 11) The drug holding body 11 can be composed of, for example, a cloth material such as a non-woven fabric, a net-like member, a sponge-like member, etc., and has air permeability in the thickness direction (front and back direction). The drug holding body 11 may have, for example, a flat shape, or may have a shape formed by being bent into a pleated shape. Further, the outer shape of the drug holding body 11 may be a polygonal shape such as a rectangular shape or a triangular shape, or may be a circular shape or an elliptical shape. A plurality of drug holding bodies 11 can also be accommodated in one container 20. In this case, the plurality of drug holding bodies 11 may be stacked in the thickness direction for accommodation, or may be arranged side by side in the vertical direction or the horizontal direction for accommodation.

[0029] In this embodiment, the drug holding body 11 has a net shape and is thinner in the ventilation direction. In the case of the drug holding body 1 formed by being bent into a pleated shape, the continuous direction of the peaks and valleys of the pleats can be the left-right direction (width direction) of the container 20. The drug holding body 11 is impregnated with a drug having the property of gradually volatilizing at normal temperature (normal temperature volatility).

[0030] Normal temperature volatility refers to the property of volatilizing into the air at normal temperature (for example, 25°C). For example, drugs with a vapor pressure of 0.001 Pa or more and 0.1 Pa or less at 25°C can be mentioned. The type of this drug is not particularly limited, and examples include insect repellents, insecticides, deodorants, disinfectants, fragrances, antiviral agents (virus inactivators), etc. Among these, only one type may be used, or two or more types may be combined. Specifically, as insecticides composed of pyrethroid compounds, for example, transfluthrin, metofluthrin, etc. can be mentioned. For these pyrethroid compounds, various optical isomers or geometric isomers exist, and any of these isomers can be used. Also, they can be used not only alone but also in combination of two or more. Further, the above drug may be an ester compound or the like. Also, the above drug may be, for example, DEET (N,N-diethyl-3-methylbenzamide), ikaridin (2-(2-hydroxyethyl)-1-piperidinecarboxylic acid 1-methylpropyl), etc. A plurality of the above drugs can also be mixed and used.

[0031] The agent may contain a solvent that dissolves the insecticidal component or the insect repellent component. Further, the agent may contain a synergist. Further, the agent may contain an antibacterial agent such as hinokitiol, tetrahydrolinalool, eugenol, citronellal, allyl isothiocyanate, etc. Further, the agent may contain a fungicide such as isopropylmethylphenol, orthophenylphenol, etc. Further, the agent may contain a fragrance or a deodorant such as citronella oil, orange oil, lemon oil, lime oil, yuzu oil, lavender oil, peppermint oil, eucalyptus oil, jasmine oil, hiba oil, hinoki oil, bamboo extract, mugwort extract, kiri oil, green tea essential oil, limonene, etc.

[0032] The agent can be impregnated into the agent holder 11. The volatilization amount of the agent can be set to about 0.01 to 0.6 mg per hour when the temperature is 25 ° C and the flow rate of the air blown onto the agent holder 11 is 0.1 to 1.5 m / second, but this is just an example and it may be outside this range. The volatilization amount of the agent can be changed by the type of the solvent, the structure, size, surface area of the agent holder 11, the material constituting the agent holder 11, the basis weight, etc.

[0033] Further, the agent can be adhered by applying or spraying the agent onto the agent holder 11, and by this, the agent can also be held on the agent holder 11. The agent can also be held on the agent holder 11 by kneading the agent into the material constituting the agent holder 11. Any method can be used to hold the agent on the agent holder 11.

[0034] (Configuration of the container 20) As also shown in FIGS. 2 to 4, the container 20 has an overall vertically long shape in which the vertical dimension is longer than the width dimension. The thickness of the container 20 is set shorter than the width dimension, and thus, the container 20 has a thick plate shape. The agent holder 11 is accommodated in the container 20 in a posture extending in the vertical direction.

[0035] As shown in Fig. 5, the container 20 has a shape that is nearly S-shaped in plan view. That is, in the plan view of the container 20, it gently curves so as to be positioned forward as it approaches the left end from the central portion in the left-right direction, while gently curving so as to be positioned rearward as it approaches the right end from the central portion in the left-right direction. The bending direction of the left side portion of the container 20 and the bending direction of the right side portion are opposite to each other, and the left side portion and the right side portion are integrated at the central portion in the left-right direction.

[0036] Since the container 20 is substantially S-shaped in plan view in this way, it is easy to receive wind from any direction. And if the wind speed is above a certain level, the container 20 will rotate around the vertical line by the received wind. By rotating like this by the wind, the medicine contained in the medicine holding body 11 can be efficiently diffused around.

[0037] Also, a left protruding plate portion 20a that protrudes forward and extends in the vertical direction is provided at the left end portion of the container 20. Further, a right protruding plate portion 20b that protrudes forward and extends in the vertical direction is provided at the right end portion of the container 20. The left protruding plate portion 20a and the right protruding plate portion 20b are parts that receive wind. Thereby, it becomes possible for the container 20 to receive wind more efficiently, and the container 20 can be rotated even at a lower wind speed. Note that the left protruding plate portion 20a and the right protruding plate portion 20b may be omitted.

[0038] As shown in Fig. 6, the container 20 includes a front member 21 and a rear member 22, and the container 20 can be obtained by combining and integrating the front member 21 and the rear member 22. The front member 21 and the rear member 22 can maintain an integrated state by a well-known coupling method such as a method using engaging claws or a welding method. Note that the container 20 may be composed of one member, or may be composed of three or more members.

[0039] The front member 21 and the rear member 22 are made of a rigid resin material such as polyethylene terephthalate (PET), polypropylene, etc. Specifically, they are made of a material that is harder and less deformable than the members constituting the drug holder 11. The front member 21 and the rear member 22 may be made of the same material or different materials.

[0040] As shown in FIGS. 1 and 2, the front member 21 includes a substantially rectangular front frame portion 21b. The open portion inside the front frame portion 21b is an opening 21a for drug diffusion. For example, when air flows into the container 20 from the opening 22a on the back side, the air containing the drug flows out from the opening 21a. Inside the front frame portion 21b, a front upper fin 21c, a front lower fin 21d, a front central fin 21e, a front upper middle fin 21f, and a front lower middle fin 21g are formed. The front upper fin 21c, the front lower fin 21d, the front central fin 21e, the front upper middle fin 21f, and the front lower middle fin 21g each extend in the vertical direction.

[0041] A plurality of front upper fins 21c are arranged at intervals in the left - right direction near the upper end portion of the front frame portion 21b and are inclined so as to be located more to the right as going forward. When assuming a virtual line C (shown in FIGS. 5, 7A, 7B, 8A, and 8B) extending from the front surface to the back surface of the container 20, the front upper fin 21c is composed of an inclined plate inclined with respect to this virtual line C. Also, a plurality of front lower fins 21d are arranged at intervals in the left - right direction near the lower end portion of the front frame portion 21b and, similar to the front upper fin 21c, are composed of an inclined plate inclined with respect to the virtual line C so as to be located more to the right as going forward. A plurality of front central fins 21e are arranged at intervals in the left - right direction at the middle portion in the vertical direction of the front frame portion 21b and, similar to the front upper fin 21c, are composed of an inclined plate inclined with respect to the virtual line C so as to be located more to the right as going forward. That is, the front upper fin 21c, the front lower fin 21d, and the front central fin 21e are inclined in the same direction with respect to the virtual line C.

[0042] A plurality of front upper intermediate fins 21f are arranged at intervals in the left - right direction between the front upper - end fin 21c and the front central fin 21e, and are composed of inclined plates inclined with respect to the virtual line C so as to be located more to the left as going forward. Also, a plurality of front lower intermediate fins 21g are arranged at intervals in the left - right direction between the front central fin 21e and the front lower - end fin 21d, and, similar to the front upper intermediate fins 21f, are composed of inclined plates inclined with respect to the virtual line C so as to be located more to the left as going forward. That is, the front upper intermediate fins 21f and the front lower intermediate fins 21g are inclined in the same direction with respect to the virtual line C.

[0043] The vertical dimensions of the front upper - end fin 21c and the front lower - end fin 21d are substantially the same, and are set shorter than the vertical dimension of the front central fin 21e, the vertical dimension of the front upper intermediate fin 21f, and the vertical dimension of the front lower intermediate fin 21g. The vertical dimensions of the front central fin 21e, the front upper intermediate fin 21f, and the front lower intermediate fin 21g are substantially the same.

[0044] The rear member 22 includes a substantially rectangular rear frame portion 22b. The open portion inside this rear frame portion 22b is an opening 22a for drug diffusion. For example, when air flows into the container 20 from the front - side opening 21a, the air containing the drug flows out from the opening 22a. Inside the rear frame portion 22b, a rear upper - end fin 22c, a rear lower - end fin 22d, a rear central fin 22e, a rear upper intermediate fin 22f, and a rear lower intermediate fin 22g are formed. The rear upper - end fin 22c, the rear lower - end fin 22d, the rear central fin 22e, the rear upper intermediate fin 22f, and the rear lower intermediate fin 22g each extend in the vertical direction.

[0045] A plurality of rear upper fins 21c are arranged at intervals in the left-right direction near the upper end of the rear frame portion 22b, and are formed of inclined plates inclined with respect to the virtual line C so as to be positioned to the right as going forward. Also, a plurality of rear lower fins 22d are arranged at intervals in the left-right direction near the lower end of the rear frame portion 22b, and are formed of inclined plates inclined with respect to the virtual line C so as to be positioned to the right as going forward, similarly to the rear upper fins 22c. A plurality of rear central fins 22e are arranged at intervals in the left-right direction in the vertical middle portion of the rear frame portion 22b, and are formed of inclined plates inclined with respect to the virtual line C so as to be positioned to the right as going forward, similarly to the rear upper fins 22c. That is, the rear upper fins 22c, the rear lower fins 22d, and the rear central fins 22e are inclined in the same direction with respect to the virtual line C.

[0046] A plurality of rear upper middle fins 22f are arranged at intervals in the left-right direction between the rear upper fins 22c and the rear central fins 22e, and are formed of inclined plates inclined with respect to the virtual line C so as to be positioned to the left as going forward. Also, a plurality of rear lower middle fins 22g are arranged at intervals in the left-right direction between the rear central fins 22e and the rear lower fins 22d, and are formed of inclined plates inclined with respect to the virtual line C so as to be positioned to the left as going forward, similarly to the rear upper middle fins 22f. That is, the rear upper middle fins 22f and the rear lower middle fins 22g are inclined in the same direction with respect to the virtual line C.

[0047] The vertical dimensions of the rear upper fins 22c and the rear lower fins 22d are substantially the same, and are set shorter than the vertical dimension of the rear central fins 22e, the vertical dimension of the rear upper middle fins 22f, and the vertical dimension of the rear lower middle fins 22g. The vertical dimension of the rear central fins 22e, the vertical dimension of the rear upper middle fins 22f, and the vertical dimension of the rear lower middle fins 22g are substantially the same.

[0048] The front fins 21c to 21g and the rear fins 22c to 22g are arranged so as to be located at the same height on the front side and the rear side. That is, the front upper end fin 21c and the rear upper end fin 21c are arranged at the same height as each other, the dimensions in the vertical direction are both set to be the same, and they overlap each other when viewed along the virtual line C. Also, the front lower end fin 21d and the rear lower end fin 22d are arranged at the same height as each other, the dimensions in the vertical direction are both set to be the same, and they overlap each other when viewed along the virtual line C. Further, the front center fin 21e and the rear center fin 22e are arranged at the same height as each other, the dimensions in the vertical direction are both set to be the same, and they overlap each other when viewed along the virtual line C. Additionally, the front upper middle fin 21f and the rear upper middle fin 22f are arranged at the same height as each other, the dimensions in the vertical direction are both set to be the same, and they overlap each other when viewed along the virtual line C. Moreover, the front lower middle fin 21g and the rear lower middle fin 22g are arranged at the same height as each other, the dimensions in the vertical direction are both set to be the same, and they overlap each other when viewed along the virtual line C.

[0049] The dimensions of the front fins 21c to 21g and the rear fins 22c to 22g in the ventilation direction may all be the same or may be different. Also, as shown in some examples in FIGS. 7A and 7B, the dimensions of the fins 21c to 21g and 22c to 22g located at the left and right ends in the left-right direction may be set shorter than the dimensions of the fins 21c to 21g and 22c to 22g located in the middle of the left-right direction in the ventilation direction.

[0050] The inclination angle of the fins 21c to 21g and 22c to 22g with respect to the virtual line C can be set, for example, in the range of 10° or more and 80° or less. The larger the inclination angle, the higher the air guiding effect by the fins 21c to 21g and 22c to 22g, which is preferable. On the other hand, when the inclination angle increases until it exceeds 80°, the openings 21a and 22a are almost blocked by the fins 21c to 21g and 22c to 22g, resulting in a sudden increase in the ventilation resistance and a decrease in the amount of the drug to be dissipated. Therefore, it is preferable that the inclination angle of the fins 21c to 21g and 22c to 22g with respect to the virtual line C is 80° or less. Also, when the inclination angle of the fins 21c to 21g and 22c to 22g with respect to the virtual line C is less than 10°, the effect of guiding a weak wind in the left-right direction will suddenly decrease. Therefore, it is preferable that the inclination angle of the fins 21c to 21g and 22c to 22g with respect to the virtual line C is 10° or more. Although not shown, fins for guiding the wind in the up-down direction may be provided. (Effect of the fins) As described above, the container 20 rotates around the vertical line when receiving wind with a certain wind speed or higher, and thereby the drug can be efficiently diffused around. On the other hand, when the wind speed is below a certain level, the container 20 hardly rotates, so the drug diffusion effect due to rotation cannot be expected. However, even in that case, the container 20 of the present embodiment is provided with the fins 21c to 21g and 22c to 22g, so that the drug can be diffused around. Hereinafter, this point will be described.

[0051] The broken lines shown in FIGS. 7A and 7B indicate the flow of the wind blowing from the front of the container 20, which is a wind with a weak force that does not rotate the container 20. The wind blowing from the front is guided by the front upper intermediate fin 21f and the front lower intermediate fin 21g while passing through the drug-impregnated body 11, as partially shown in FIG. 7A. The wind passing through the drug-impregnated body 11 volatilizes the drug. Then, the wind containing the drug is guided to the right by the rear upper intermediate fin 22f and the rear lower intermediate fin 22g.

[0052] Also, as partially shown in FIG. 7B, the wind blowing from the front passes through the drug-impregnated body 11 while being guided by the front upper fins 21c, the front lower fins 21d, and the front center fin 21e. The wind passing through the drug-impregnated body volatilizes the drug. Then, the wind containing the drug is guided leftward by the rear upper fins 22c, the rear lower fins 22d, and the rear center fin 22e.

[0053] As described above, the wind containing the drug is guided by the rear fins 22c to 22g and dispersed left and right, and then discharged from the back side of the container 20. In this way, since the wind containing the drug can be dispersed left and right and discharged, the diffusibility of the drug is good even when the container 20 does not rotate.

[0054] Incidentally, the same applies when wind blows from the back of the container 20, which is the opposite of the above. That is, in this case, the wind blowing from the back of the container 20 passes through the drug-impregnated body 11 while being guided by the rear fins 22c to 22g, and then is dispersed left and right by the front fins 21c to 21g and discharged from the front of the container 20. Thus, according to the configuration of the present embodiment, the drug can be diffused around whether the wind blows from the front or the back.

[0055] By the way, the wind does not always blow from the front or the back, and it is also conceivable that the wind blows from the left and right. When the wind blows from the left and right to the container 20, the wind will flow substantially parallel to the drug-impregnated body 11, so the wind will not pass through the drug-impregnated body 11 as it is, and the volatilization of the drug cannot be expected. However, according to the present embodiment, even when the wind blows from the left and right, the drug can be diffused well. This will be described below.

[0056] The flow of wind blowing from the left of the container 20 is indicated by the dashed line in Fig. 8A, and it is wind with a weak force that does not rotate the container 20. As partially shown in Fig. 8A, the wind blowing from the left is received by the rear upper fin 22c, rear lower fin 22d, and rear central fin 22e on the back side of the container 20, and is guided toward the chemical impregnated body 11 inside the container 20. The wind guided in this way volatilizes the chemical by passing through the chemical impregnated body 11. Then, the wind containing the chemical flows out from the front side of the container 20 while being guided by the front upper fin 21c, front lower fin 21d, and front central fin 21e.

[0057] The flow of wind blowing from the right of the container 20 is indicated by the dashed line in Fig. 8B, and it is wind with a weak force that does not rotate the container 20. As partially shown in Fig. 8B, the wind blowing from the right is received by the front upper fin 21c, front lower fin 21d, and front central fin 21e on the front side of the container 20, and is guided toward the chemical impregnated body 11 inside the container 20. The wind guided in this way volatilizes the chemical by passing through the chemical impregnated body 11. Then, the wind containing the chemical flows out from the back side of the container 20 while being guided by the rear upper fin 22c, rear lower fin 22d, and rear central fin 22e.

[0058] As described above, when wind blows from the left and right of the container 20, the fins 21c - 21g, 22c - 22g receive the wind and guide it toward the chemical impregnated body 11 inside the container 20. With such a configuration, even when the wind blows substantially parallel to the chemical impregnated body 11, the wind can be applied to the chemical impregnated body 11 to volatilize the chemical.

[0059] In this way, even when the container 20 does not rotate, the chemical can be diffused into the surroundings regardless of the direction from which the wind blows. Note that the above description is based on the premise of the container 20 of the present embodiment configured to rotate by the wind, so it is only an explanation limited to the case when the wind is weak (when the container 20 does not rotate). In this case, when the wind is strong, the drug is diffused by the rotation of the container 20. However, when the container 20 is fixed so as not to rotate, the diffusion effect by the fins 21c to 21g, 22c to 22g can of course be obtained even in strong winds. That is, the effect by the fins 21c to 21g, 22c to 22g is not limited to the case where the container 20 is configured to rotate, and it also exerts its efficacy even in the container 20 fixed so as not to rotate.

[0060] That is, the container 20 is provided with a front upper intermediate fin 21f and a front lower intermediate fin 21g for guiding the wind introduced from the front side opening 21a in the right direction (the first direction), and a rear upper intermediate fin 22f and a rear lower intermediate fin 22g (the first guiding part), and a front upper end fin 21c, a front lower end fin 21d, and a front central fin 21e for guiding in the left direction (the second direction opposite to the first direction), and a rear upper end fin 22c, a rear lower end fin 22d, and a rear central fin 22e (the second guiding part). The first guiding part includes a front upper intermediate fin 21f and a front lower intermediate fin 21g formed on the front side of the container 20b, and a rear upper intermediate fin 22f and a rear lower intermediate fin 22g formed on the back side of the container 20b. Also, the second guiding part includes a front upper end fin 21c, a front lower end fin 21d, and a front central fin 21e formed on the front side of the container 20b, and a rear upper end fin 22c, a rear lower end fin 22d, and a rear central fin 22e formed on the back side of the container 20b. The number of the fins 21c to 21g, 22c to 22g is not limited to the illustrated number.

[0061] As shown in FIGS. 1 to 3, on the front side and the back side of the upper part of the container 20, a front side recess 21h (shown in FIG. 2) and a back side recess 22f (shown in FIG. 3) to which the suspension member 40 is attached are formed so as to be recessed toward the inside of the container 20. The front side recess 21h and the back side recess 22f are positioned at the center in the left-right direction of the container 20. At the center in the left-right direction and the center in the front-back direction of the container 20, a turning center line D of the container 20 is located, and this turning center line D extends in the vertical direction of the container 20. When the container 20 is suspended by the suspension member 40, the turning center line D is oriented in the vertical direction. The connection structure of the suspension member 40 to the container 20 is not limited to the illustrated structure.

[0062] (Configuration of the suspension member 40) As shown in FIG. 2, FIG. 3, etc., the suspension member 40 is configured to suspend the container 20 as an article so as to be rotatable around a vertical line (turning center line D), and includes a suspension hook 40A, a thimble 40B, and a clip 40C. The thimble 40B and the clip 40C may be provided as necessary. Even if the thimble 40B is omitted and a thread is used instead of the thimble 40B, it is possible to turn the container 20. Also, the lower part of the thimble 40B may be directly connected to the container 20 without providing the clip 40C.

[0063] The container 20 can be suspended from a rod-shaped member 100 extending in a substantially horizontal direction as shown in FIGS. 14A and 14B. In this case, the suspension hook 40A can be referred to as a suspension hook 40A for suspending an article from the rod-shaped member 100. Further, although details will be described later, as shown in FIG. 15, an article can also be suspended from a large-diameter rod-shaped member 101 by the suspension hook 40A. Examples of the rod-shaped members 100 and 101 include a drying pole, various poles, and arms. The rod-shaped members 100 and 101 do not have to be installed exactly horizontally and may be slightly inclined. Further, as shown in FIG. 16, the container 20 can be suspended from a string 102. In this case, the suspension hook 40A can be referred to as a suspension hook 40A for suspending an article from the string 102. Examples of the string 102 include strings, ropes, cords, cables, and long members used for drying or other purposes, and are stretched in the horizontal direction. A suspension structure is configured by the suspension hook 40A and the snap hook 40B. The snap hook 40B is a connecting member for connecting a base member 52, which will be described later, to the container 20.

[0064] As shown in FIG. 1, the snap hook 40B, which is a component of the suspension structure, is a freely rotatable metal ring and is a well-known member. The snap hook 40B is sometimes called a snapback. In this example, when the upper part of the snap hook 4B is fixed, the lower part can easily rotate around the vertical line. That is, the upper part of the snap hook 40B is connected to the lower part of the suspension hook 40A, while a clip 40C attached to the container 20 is connected to the lower part of the snap hook 40B. The clip 40C is fixed to the container 20 by fitting into the front-side recess 21h and the back-side recess 22f of the container 20.

[0065] The suspension hook 40A is provided with a tightening portion 41. The tightening portion 41 is formed in substantially the upper half of the suspension member 40, and is provided with a tightening portion 41 that surrounds the rod-shaped members 100 and 101 in the circumferential direction and has a part of the circumferential direction made discontinuous and openable. As shown in FIG. 11 and the like, the tightening portion 41 has a shape close to a C shape as a whole when the container 20 is not suspended.

[0066] In the description of this embodiment, as shown in FIGS. 9 to 11 and the like, the front, back, left, and right of the suspension hook 40A are defined. However, this is for the convenience of explanation and does not limit the direction during use. During use, the suspension hook 40A may be arranged such that the back faces the front side of the container 20, or the suspension hook 40A may be arranged such that the right or left faces the front side of the container 20.

[0067] As shown in FIG. 11, when the suspension hook 40A is viewed from the front or the back, the tightening portion 41 is configured to be openable in the horizontal direction. Specifically, when the suspension hook 40A is viewed from the front, a discontinuous portion is located on the left side of the tightening portion 41. Therefore, the left side of the tightening portion 41 can be opened, and the upper left portion (one side in the circumferential direction) 42 and the lower left portion (the other side in the circumferential direction) 43 of the tightening portion 41 are arranged at intervals in the vertical direction. Note that a discontinuous portion may be located on the right side of the tightening portion 41.

[0068] The tightening portion 41 is made of a resin material having flexibility and flexibility. Examples of such a resin material include polypropylene, etc., but other resin materials can also be used. The tightening portion 41 preferably has elasticity. Since the tightening portion 41 has elasticity, for example, even if the open portion of the tightening portion 41 is opened wide as shown in FIG. 14A, the shape can be restored as shown in FIG. 11 by removing the force thereafter.

[0069] Since the tightening portion 41 has the properties (flexibility and flexibility) described above, as shown in FIGS. 14A and 15, it is possible to deform the tightening portion 41 so that the distance between the upper left portion 42 and the lower left portion 43 thereof increases. Thereby, the rod-shaped members 100 and 101 can be inserted inside the tightening portion 41. Further, the distance between the upper left portion 42 and the lower left portion 43 is deformed so as to be narrowed, and as shown in FIG. 14B, the upper left portion 42 and the lower left portion 43 can be arranged so as to overlap each other in the radial direction. At this time, the upper left portion 42 is in a state of overlapping the outer surface of the lower left portion 43.

[0070] As shown in FIG. 11, a plurality of teeth 42a protruding radially inward from the inner surface are formed on the inner surface of the upper left portion 42 of the tightening portion 41 so as to be arranged in the circumferential direction. An engaging portion is constituted by these teeth 42a. All the teeth 42a have the same shape and are shaped long in the front-rear direction to ensure a wide tooth surface. The interval between the teeth 42a can be arbitrarily set. For example, the teeth 42a may be provided so as to be adjacent to each other, or a gap may be formed between the teeth 42a.

[0071] On the outer surface of the lower left portion 43 of the tightening portion 41, a plurality of grooves 43a extending in the front-rear direction are formed so as to be arranged in the circumferential direction. An engaged portion that engages with the teeth 42a is constituted by these grooves 43a. The interval between adjacent teeth 42a and the interval between adjacent grooves 43a are set to be the same. Thereby, as shown in FIG. 14B, a plurality of teeth 42a can be engaged with a plurality of grooves 43a at once. Engaging a plurality of teeth 42a with a plurality of grooves 43a at once is preferable because the coupling strength between the lower left portion 42 and the lower left portion 43 is increased. Note that one tooth 42a may be engaged with one groove 43a. Although not shown, teeth may be formed on the lower left portion 43 and grooves may be formed on the upper left portion 42. Further, convex portions or protrusions may be formed instead of the teeth, and concave portions or the like may be formed instead of the grooves.

[0072] By deforming the tightening portion 41 so that the distance between the upper left portion 42 and the lower left portion 43 is reduced and by reducing the diameter of the tightening portion 41, the overlapping range between the lower left portion 42 and the lower left portion 43 becomes wider, so that many teeth 42a can be engaged with many grooves 43a. In this embodiment, since the intervals between adjacent teeth 42a, 42a and the intervals between adjacent grooves 43a, 43a are set narrowly, for example, to be 0.5 mm or more and 2.0 mm or less, the diameter of the tightening portion 41 can be finely adjusted. Also, the adjustment range of the diameter of the tightening portion 41 can be set according to the formation range in the circumferential direction of the teeth 42a and the formation range in the circumferential direction of the grooves 43a. The adjustment range of the diameter of the tightening portion 41 can be, for example, in the range of 5 mm or more and 30 mm or less.

[0073] (Function of the tightening portion) With the above configuration, when the container 20 is hung on the rod-shaped member 100, as shown in FIG. 14B, by adjusting the diameter of the tightening portion 41 to match the outer diameter of the rod-shaped member 100, the rod-shaped member 100 can be tightened. As a result, since the suspension hook 40A is fixed to the rod-shaped member 100, it is possible to prevent the chemical diffuser 1 from moving in the longitudinal direction of the rod-shaped member 100 even if, for example, a strong wind blows and the container 20 is fanned by the wind.

[0074] On the other hand, as shown in FIG. 15, assuming a case where the container 20 is hung on a large-diameter rod-shaped member 101, the upper left portion 42 and the lower left portion 43 cannot be overlapped in the radial direction, and the tightening portion 41 may remain open. In this case, the teeth 42a and the grooves 43a cannot be engaged. However, even in this case, the rod-shaped member 101 can be tightened by the tightening portion 41.

[0075] That is, in this case, since the tightening part 41 is in an open state compared to the state where no force is applied (FIG. 11), a force is generated by the elastic force of the tightening part 41 to close the tightening part 41. Due to this elastic force, the rod-shaped member 101 can be clamped in the vertical direction between the upper part and the lower part, and the rod-shaped member 101 can be tightened. Thereby, even when the container 20 is hung on a large-diameter rod-shaped member 101, the suspension hook 40A can be fixed to the rod-shaped member 101, so that even when the wind is strong, it is possible to prevent the chemical diffuser 1 from moving in the longitudinal direction of the rod-shaped member 101.

[0076] On the outer surface of the upper left part 42 of the tightening part 41, an upper finger contact part (first finger contact part) 42b for placing a finger when tightening the tightening part 41 is provided. Also, on the outer surface of the lower left part 43 of the tightening part 41, a lower finger contact part (second finger contact part) 43b for placing a finger when tightening the tightening part 41 is provided. The upper finger contact part 42b is located directly above the part where the teeth 42a are formed, and has a plate shape extending in the left-right direction and the front-back direction. It is possible for the user to place or rest a finger on the upper surface of this upper finger contact part 42b. On the other hand, the lower finger contact part 43b is located below the lowermost groove 43a, and has a plate shape extending in the left-right direction and the front-back direction. It is possible for the user to place a finger on the lower surface of the lower finger contact part 43b.

[0077] When viewed from the vertical direction, the shapes and positions of the upper finger contact part 42b and the lower finger contact part 43b are set such that at least a part of the upper finger contact part 42b overlaps at least a part of the lower finger contact part 43b. Also, on the upper surface of the upper finger contact part 42b and the lower surface of the lower finger contact part 43b, an anti-slip uneven shape, a dimpled shape, a thin groove, or the like is provided.

[0078] For example, when the thumb is placed on the upper surface of the upper finger contact portion 42b and the index finger is placed on the lower surface of the lower finger contact portion 43b and a force is applied to bring the thumb and the index finger closer to each other, the lower left portion 42 and the lower left portion 43 approach each other, and the inner surface of the lower left portion 43 is arranged to overlap the outer surface of the lower left portion 42. Thereby, the tooth 42a and the groove 43a can be engaged. When the applied force is increased, as shown in FIG. 14B, the diameter of the clamping portion 41 becomes smaller, so that the rod-shaped member 100 can be clamped by the clamping portion 41, and in this state, the tooth 42a and the groove 43a are engaged to maintain the clamped state by the clamping portion 41.

[0079] A protruding portion 42c that curves radially outward is formed at the lower part of the upper left portion 42 of the clamping portion 41. The tip of the protruding portion 42c in the protruding direction is located radially outside the lower left portion 43. For example, as shown in FIG. 14A, when the rod-shaped member 100 is inserted into the inside of the clamping portion 41, the rod-shaped member 100 can be brought into contact with the lower surface of the protruding portion 42c and guided to the inside of the clamping portion 41. Further, when changing the clamping portion 41 in the open state shown in FIG. 11 to the closed state shown in FIG. 14B, the upper end portion of the lower left portion 43 contacts the lower surface of the protruding portion 42c, so that the lower left portion 43 can be guided inside the upper left portion 42. Furthermore, when opening the clamping portion 41, from the closed state of the clamping portion 41, by lifting the protruding portion 42c upward, the engagement between the tooth 42a and the groove 43a can be released, and the clamping portion 41 can be easily opened. Thereby, the drug diffuser 1 can be removed from the rod-shaped member 100.

[0080] On the upper portion of the tightening portion 41, a bent portion 44 is provided which is bent upwardly protruding from the center portion in the left-right direction. The bent portion 44 has a shorter dimension in the left-right direction as it approaches the upper end portion of the bent portion 44, and has a shape that tapers upward when viewed from the front-back direction. By forming the bent portion 44, a concave portion 44a that is recessed upward is formed on the upper inner surface of the tightening portion 41. The width (dimension in the circumferential direction) of the concave portion 44a becomes narrower as it goes upward. As shown in FIG. 16, when the string 102 is suspended, the string 102 enters the concave portion 44a and gets caught. Thereby, the suspension member 40 is stabilized.

[0081] Since the bent portion 44 is formed, when the tightening portion 41 is opened, the bent portion 44 elastically deforms so as to open, and thereby, a large amount of elastic deformation of the tightening portion 41 can be ensured. Further, since the bent portion 44 functions like a spring, the spring property of the tightening portion 41 can be enhanced.

[0082] Also, on the lower portion of the tightening portion 41, a lower protruding portion 45 that protrudes downward is provided. An indicator 50 described later is provided on the lower portion of the lower protruding portion 45. Further, on the outer surface of the tightening portion 41, an upper rib 46 and a side rib 47 that protrude radially outward are provided. The upper rib 46 extends from the outer surface of the bent portion 44 to the upper finger contact portion 42b. Also, the side rib 47 extends from the outer surface of the bent portion 44 to the lower protruding portion 45. By forming the upper rib 46 and the side rib 47, the strength of the tightening portion 41 can be enhanced and the fall when suspended from a large-diameter rod-shaped member 101 as shown in FIG. 15 can be suppressed. The upper rib 46 and the side rib 47 may be provided as necessary and may be omitted.

[0083] (Configuration of the indicator 50) The indicator 50 is a dial-type display device provided to indicate the timing when the efficacy of the drug held in the drug-impregnated body 11 is lost. The indicator 50 is provided on the hanging hook 40A as described above. In a conventional drug diffuser, the indicator was provided on the container, which caused various restrictions on the shape of the container and the like. In particular, in the case of the dial-type indicator 50, it may be desired to set a relatively large dial 51 to enhance visibility. If such a dial 51 is provided on the container 20, the opening area of the container 20 may become narrow, and the volatilization efficiency of the drug may decrease. In the present embodiment, since the indicator 50 is arranged on the hanging hook 40A instead of the container 20, the opening area of the container 20 does not decrease. Further, since the shape of the container 20 is not restricted by the indicator, the container 20 can have a shape curved in an S shape in plan view as in the present embodiment, for example.

[0084] The indicator 50 is provided at the lower part of the lower protruding portion 45 that protrudes downward from the tightening portion 41, so it is arranged below the tightening portion 41. That is, the indicator 50 is arranged below the tightening portion 41 and is not on the tightening portion 41, so the flexibility of the tightening portion 41 is not inhibited by the indicator 50. As a result, when the hanging hook 40A is hung on the rod-shaped members 100 and 101, the tightening portion 41 can be easily deformed and hung.

[0085] The indicator 50 includes a dial 51 on which a plurality of numbers are displayed, a base member 52 that rotatably supports the dial 51, and a cover portion 53 formed to cover at least a part of the surface of the dial 51. It is a dial-type display device configured to display desired information by rotating the dial 51. As described above, the indicator 50 of the present embodiment is for displaying the timing when the efficacy of the drug held in the drug holder 11 disappears, as an example of desired information, and can also be called an end-stage display device. Incidentally, the indicator 50 can also display the start time of use of the drug diffuser 1, as an example of desired information, and in this case, it can also be called a start-stage display device. By displaying the start time of use of the drug diffuser 1, the end stage can be grasped.

[0086] As shown in FIGS. 12A and 12B, the dial 51 is, for example, in the shape of a circular plate and is made of a resin material or the like. The dial 51 may be in the shape of a polygonal plate. A through hole 51a penetrating in the front-rear direction is formed at the center of the dial 51. Since the through hole 51a is a hole for making the dial 51 rotatable, it is circular. The center line of the through hole 51a becomes the rotation center line of the dial 51.

[0087] On the front surface 51b of the dial 51, a plurality of numbers are displayed so as to be arranged in the circumferential direction. The numbers displayed here indicate "months" and are 1 to 12, but this is just an example, and the AD year, characters, or symbols may be displayed. Also, the same numbers as those displayed on the front surface 51b are displayed on the back surface 51c of the dial 51. The numbers on the front surface 51b of the dial 51 and the numbers on the back surface 51b are aligned in the circumferential direction. Therefore, for example, the "1" on the back surface 51b is located directly behind the "1" on the front surface 51b of the dial 51. The front surface 51b and the back surface 51c of the dial 51 are each display surfaces for displaying the timing when the efficacy of the drug disappears. Incidentally, only one of the front surface 51b and the back surface 51c of the dial 51 may display numbers.

[0088] The dial 51 is formed with a cylindrical peripheral wall portion 51d that protrudes rearward from the peripheral edge of the through hole 51a and extends in the circumferential direction. The inner diameter of the peripheral wall portion 51d is set to be the same as the diameter of the through hole 51a. Further, on the rear side of the dial 51, a convex portion 51e is provided radially outward of the peripheral wall portion 51d. The convex portion 51e protrudes radially outward. A part of the peripheral wall portion 51d in the circumferential direction is interrupted, and the convex portion 51e is arranged so as to correspond to this interrupted portion.

[0089] The base member 52 is disposed on the rear side of the dial 51 and is a portion that rotatably supports the dial 51. The base member 52 has a substantially circular plate shape that extends in the vertical and horizontal directions along the rear side of the dial 51, and thus can also be called a support plate. The lower part of the lower protruding portion 45 of the tightening portion 41 is integrally formed on the upper part of the base member 52. A connecting plate portion 54 that protrudes downward is provided at the lower part of the base member 52. The upper part of the sulcan 40B for connecting to the container 20 is attached to the lower part of this connecting plate portion 54.

[0090] As shown in FIG. 10, two rear side mark portions 52a, 52a for aligning the numbers of the dial 51 are provided on the back surface of the base member 52. The rear side mark portion 52a can be composed of, for example, an arrow, a symbol, a line segment, a character, etc., and in this embodiment, it is composed of a line segment of a predetermined length extending in the radial direction. One of the rear side mark portions 52a indicates the start period, and the other rear side mark portion 52a indicates the end period. For example, when starting use from January, the "1" on the back surface 51c of the dial 51 is aligned with one of the rear side mark portions 52a. Then, the other rear side mark portion 52a indicates "9". That is, when a usage period of 9 months is assumed, the relative positions of both rear side mark portions 52a, 52a are set such that the other rear side mark portion 52a indicates the month 9 months after the month aligned by one of the rear side mark portions 52a. The relative positions of the rear side mark portions 52a, 52a can be set arbitrarily. Also, for example, when a usage period of 1 year is assumed, only one rear side mark portion 52a is sufficient.

[0091] The cover portion 53 is a portion disposed on the front side of the dial 51, and is configured to cover the radially inner region of the surface 51b of the dial 51 and expose the radially outer region (the region where numbers are displayed). The cover portion 53 has a circular plate shape similar to the base member 52. On the surface of the cover portion 53, two front side mark portions 53a, 53a for aligning with the numbers of the dial 51 are provided. The front side mark portion 53a is for indicating the start period and the end period, similar to the back side mark portion 52a.

[0092] As shown in FIGS. 12A and 12B, a part of the circumferential direction of the cover portion 53 and a part of the circumferential direction of the base member 52 are integrally formed via a thin hinge 55. In this embodiment, one end portion of the thin hinge 55 is integrated with the right edge portion of the cover portion 53, and the other end portion of the thin hinge 55 is integrated with the right end portion of the base member 52. The thin hinge 55 is formed thinner than the wall thickness of the cover portion 53 and the base member 52, and is a portion that bends with a smaller force compared to the cover portion 53 and the base member 52.

[0093] Figures 12A and 12B show the shapes of the tightening part 41, the lower protruding part 45, the base member 52, the cover member 53, the connecting plate part 54, and the thin hinge 55 immediately after molding. As shown in these figures, the tightening part 41, the lower protruding part 45, the base member 52, the cover member 53, the connecting plate part 54, and the thin hinge 55 are integrally molded with the same resin material. Immediately after molding, the thin hinge 55 is in an open state, that is, the base member 52 and the cover member 53 are in a deployed state. In the deployed state, the hanging hook 40A, the base member 52, and the cover member 53 pass through substantially the same plane and are arranged to virtually form the plane. That is, when integrally molding the hanging hook 40A, the base member 52, and the cover member 53, if the hanging hook 40A, the base member 52, and the cover member 53 are greatly deviated from the same plane, the difference between the deep part and the shallow part of the mold becomes large, the mold structure becomes complicated, and there is a concern that molding defects are likely to occur. In contrast, as described above, by arranging the hanging hook 40A, the base member 52, and the cover member 53 so as to form substantially the same plane, the mold structure for integral molding becomes simple, the moldability becomes good, and thus the cost can be further reduced.

[0094] On the front surface of the base member 52, three base-side columnar parts 52b are formed at intervals in the circumferential direction, which are inserted into the through hole 51a of the dial 51 and rotatably support the dial 15. The base-side columnar parts 52b extend in the front-back direction, and the three base-side columnar parts 52b constitute one support shaft for supporting the dial 51. That is, the three base-side columnar parts 52b are arranged at intervals in the circumferential direction of the support shaft. The number of the base-side columnar parts 52b is not limited to three, and may be two or less, or four or more.

[0095] Further, the outer surfaces of the three base-side columnar portions 52b are formed by arc surfaces located on the same circumference, and are formed so as to be in sliding contact with the inner circumferential surface of the through hole 51a of the dial 51. When the dial 51 is rotated, the inner circumferential surface of the through hole 51a slides on the outer surfaces of the three base-side columnar portions 52b, enabling the dial 51 to rotate smoothly.

[0096] On the other hand, on the back surface of the cover portion 53, cover-side columnar portions 53b are formed which are inserted between the base-side columnar portions 52b and joined to the base-side columnar portions 52b. The cover-side columnar portions 53b are formed in a triangular tube shape and are fitted inside the three base-side columnar portions 52b, thereby being in a state of being joined to the inner surfaces of the three base-side columnar portions 52b. For example, engaging claws or the like can be provided on the outer surface of the cover-side columnar portion 53b and the inner surfaces of the three base-side columnar portions 52b to engage the two. The shape of the cover-side columnar portion 53b is not limited to a triangular tube shape, and any shape that can be fitted with the base-side columnar portion 52b to obtain a rotation-preventing effect may be used, such as a polygon such as a quadrilateral or a pentagon.

[0097] Since the cover-side columnar portion 53b is in a triangular tube shape and the three base-side columnar portions 52b are arranged on its outer surface and the two are joined, relative rotation of the base member 52 and the cover portion 53 around the rotation center line of the dial 51 is prevented. That is, a rotation-preventing structure is configured by the cover-side columnar portion 53b and the base-side columnar portion 52b to prevent relative rotation of the base member 52 and the cover portion 53, and the indicator 50 is provided with the rotation-preventing structure. Thereby, for example, even if the thin hinge 55 is broken, the base member 52 and the cover portion 53 do not rotate relative to each other, and the start and end of the front and back are correctly maintained.

[0098] A specific example of the peripheral stop structure will be described. In this embodiment, the three tops 53c of the cover-side columnar portions 53b are respectively arranged between the base-side columnar portions 52b adjacent in the circumferential direction. When one of the base member 52 and the cover portion 53 attempts to rotate relative to the other, the top 53c hits the base-side columnar portion 52b, thereby preventing relative rotation. The top 53c is a stopper portion.

[0099] An annular wall 52e is formed at the peripheral edge of the base member 52. The annular wall 52e protrudes toward the front side and extends in an annular shape around the rotation center line of the dial 51. The radial center portion of the annular wall 52e coincides with the rotation center line of the dial 51. A number of engaging protrusions 52f are provided on the inner peripheral surface of the annular wall 52e so as to be arranged in the circumferential direction. When the cover-side columnar portion 53b is inserted between the three base-side columnar portions 52b and the cover portion 53 is aligned with the base member 52, the tip of the convex portion 51e is arranged to contact the engaging protrusion 52f within the annular wall 52e. When the convex portion 51e and the engaging protrusion 52f come into contact and engage with each other, it becomes difficult for the dial 51 to rotate, and unexpected rotation is prevented. On the other hand, when the dial 51 is deliberately rotated with a finger, the convex portion 51e elastically deforms and the engagement state with the engaging protrusion 52f is released, enabling the dial 51 to rotate.

[0100] (When using the drug diffuser 1) The drug diffuser 1 configured as described above can be used outdoors by hanging it on the rod-shaped members 100 and 101 as shown in FIGS. 14B and 15, or by hanging it on the string 102 as shown in FIG. 16. When natural wind hits the container 20 in the hanging state, if the force of the wind is strong, since the hanging member 40 is provided with the swan neck 40B, the container 20 rotates. The stronger the force of the wind, the higher the rotation speed of the container 20. Thereby, the drug can be efficiently diffused.

[0101] On the other hand, in the case of a gentle breeze, the container 20 may not rotate. However, as described above, the drug diffuser 1 of this embodiment can effectively diffuse the drug even when it does not rotate.

[0102] (Efficacy test under gentle breeze) Therefore, the efficacy test under gentle breeze will be described. The test under gentle breeze was conducted in an 8-mat airless constant temperature room with 5 air changes per hour. At a position 0.1 m away from the wall of this test chamber, at three heights of 0.5 m, 1.0 m, and 2.0 m respectively, insect nets containing test insects were hung at three locations horizontally at 90 cm intervals parallel to the wall. That is, a total of 3×3 = 9 insect nets were installed vertically and horizontally. The test insects were female Aedes aegypti. The chemical agent impregnated in the chemical agent-impregnated body 11 is an insecticide composed of a pyrethroid-based compound. The chemical agent dispenser 1 was hung at a height of 1 m, 1.1 m away from the front of the leftmost insect net (1.2 m away from the wall), and the container 20 was blown with wind by a fan so that the wind speed near the front of the container 20 was 0.5 m / s. At this wind speed, the container 20 of this embodiment hardly rotates. After installing the insect nets, the chemical agent dispenser 1 was installed, and after the installation of the chemical agent dispenser 1, the number of knockdown insects over time was observed. The test was repeated 3 times, and the KT50 value was obtained by Bliss's Probit method from the knockdown rate at each observation time.

[0103] As a result, for the test insects placed at a location far from the chemical agent dispenser 1, the KT50 value (minutes) was 9.12 to 10.32, and the efficacy of the chemical agent was sufficiently obtained. Also, for the test insects placed near the chemical agent dispenser 1, the KT50 value (minutes) was 4.54 to 6.37, indicating that the efficacy of the chemical agent was even higher.

[0104] Next, as a comparative example, a container not equipped with fins 21c to 21g and 22c to 22g (described in Japanese Patent Application Laid-Open No. 2011-19507) was prepared, and the same test was conducted. As a result, for the test insects placed at a location far from the chemical agent dispenser of the comparative example, the KT50 value (minutes) was 11.33 to 12.93, indicating that it took more time to knockdown than in the example. Also, for the test insects placed near the chemical agent dispenser of the comparative example, the KT50 value (minutes) was 4.71 to 6.92, indicating that it was equivalent to or took more time to knockdown than in the example.

[0105] As described above, it was confirmed that when there is a gentle breeze (when the container does not rotate), the drug diffuser 1 of this embodiment has an equal or higher efficacy than the drug diffuser of the comparative example. Particularly at a position far from the drug diffuser, it was confirmed that the drug diffuser 1 of this embodiment has a significantly improved efficacy compared to the comparative example. This indicates that the drug diffuser 1 of this embodiment can diffuse the drug over a wider range when there is a gentle breeze.

[0106] The reason for the high efficacy in the case of a gentle breeze is that, as shown in FIGS. 7A and 7B, the fins 21c to 21g and 22c to 22g guide the drug to both the left and right sides and diffuse it over a wide range. Also, as shown in FIG. 8A when the wind blows from the left and as shown in FIG. 8B when the wind blows from the right, the drug can be diffused. Therefore, high efficacy can be obtained regardless of the installation direction of the drug diffuser 1.

[0107] (Function and effect of the embodiment) As described above, according to this embodiment, since a part of the circumferential direction of the tightening portion 41 of the hanging hook 40A is discontinuous, as shown in FIG. 14A, by deforming the tightening portion 41 so that the discontinuous portion opens, it becomes possible to insert the rod-shaped member 100 into the inside of the tightening portion 41 from the opened portion of the tightening portion 41. Then, as shown in FIG. 14B, when the teeth 42a are engaged with the grooves 43a, the tightening portion 41 closes and the rod-shaped member 100 is tightened. At this time, since the plurality of teeth 42a are arranged in the circumferential direction, by changing the teeth 42a with which the grooves 43a are engaged, the circumferential length of the tightening portion 41 can be surely tightened to match the circumferential length of the rod-shaped member 100. Therefore, since the hanging hook 40A made of an integrally molded resin product can be fixed to the rod-shaped member 100, cost reduction can be achieved.

[0108] Also, when the chemical diffuser body 10 is suspended by the suspension hook 40A, air enters and exits through the openings 21a and 22a of the container 20, causing the chemical to be diffused to the outside. Further, since the indicator 50 is provided on the suspension hook 40A, the opening area of the container 20 will not decrease, and the indicator 50 can be provided regardless of the shape of the container 20.

[0109] In addition, since the base member 52 and the cover portion 53 of the indicator 50 are integrally formed via the thin hinge 55, the number of parts is reduced. Also, at the time of assembly, the dial 51 is placed on top of the base member 52, and by bending the thin hinge 55 and arranging the cover member 53 on the front side of the dial 51, an indicator 50 that rotatably supports the dial 51 can be obtained, facilitating the assembly work.

[0110] The above-described embodiments are merely illustrative in every respect and should not be construed in a limiting sense. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention. The chemical diffuser 1 can also be used without being rotated. For example, the container 20 can be suspended from a doorknob (not shown) by the suspension member 40 and used.

[0111] Also, the article suspended by the suspension member 40 is not limited to the chemical diffuser 1, and various other articles can be suspended. The suspension member 40 can also be used, for example, as part of a clothes hanger.

Industrial Applicability

[0112] As described above, the present invention can be applied to a chemical diffuser that diffuses, for example, a chemical for pest control into the air.
