Description

TECHNICAL FIELD The present invention relates to a suspension hook used when suspending an article and a drug diffuser having the same.

For example, Patent Literature 1 discloses that an insect repellent drug diffuser is used by hanging it from a pole or the like outdoors. The insect repellent drug diffuser of Patent Document 1 is formed by housing an impregnated sheet impregnated with an insect repellent drug in a plate-shaped container, and a hook is attached to the upper part of the container for turning the container down. It is

Further, Patent Document 2 discloses a hanger for drying clothes. The hook of this hanger has a rotating arm having an upper arm and a lower arm that is rotatably connected to the hook body via a support shaft. By rotating the rotating arm, the rod can be sandwiched between the hook body and the rotating arm.

Moreover, Patent Document 3 discloses a hook that is hung from a clothesline. This hook swings between a state in which the notch is closed and a state in which the notch is opened, on a hook body having a notch for passing a rod through, and a shaft provided below the notch in the hook body. It comprises a retainer member that can be supported and a spring that biases the retainer member so as to close the notch.

By the way, by suspending an insect repellent drug diffuser as disclosed in Patent Document 1 outdoors on a rod or the like, it is possible to receive the wind and diffuse the drug over a wide range, thereby enhancing the efficacy of the drug. However, when the inventors of the present application have studied, when the drug diffuser of Patent Document 1 is hung on a clothesline, the drug diffuser moves in the longitudinal direction of the clothesline when the wind hits it. I found out that there is a problem. In particular, since clothes are often hung on the clothesline, there is a need to prevent the chemical diffuser from coming into contact with the clothes. Also, if it is hung from a pole other than a clothesline, the wind may move it to the end of the pole and cause it to fall.

Therefore, it is conceivable to sandwich the rod between hooks and fix the hooks to the rod as disclosed in Patent Documents 2 and 3, for example. However, Patent Document 2 requires a rotating arm, a support shaft, and a hook main body as parts, and Patent Document 3 requires a hook main body, a retaining member, and a spring as parts, resulting in a large number of parts. If the number of parts is large, the number of assembly man-hours increases, resulting in high costs. In addition, it is necessary to devise ways to prevent disassembly during use, which may lead to further increases in costs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to reduce the cost by constructing a suspension hook that can be fixed to a rod-like member with a small number of parts.

In order to achieve the above object, the first disclosure assumes a suspension hook for suspending an article on a rod-like member extending in a substantially horizontal direction. The hanging hook includes a tightening portion that surrounds the rod-shaped member in the circumferential direction and that is partially discontinuous in the circumferential direction and is formed to be openable. In addition, a plurality of engaging portions are formed so as to be arranged in the circumferential direction on one side of the tightening portion in the circumferential direction, and a to-be-engaged portion that engages with the engaging portion is formed on the other side of the tightening portion in the circumferential direction. part is formed.

According to this configuration, since a portion of the tightening portion in the circumferential direction is discontinuous, the tightening portion is opened by deforming the tightening portion so as to open the discontinuous portion. It becomes possible to put the rod-shaped member inside the tightening part from the part. After that, when the engaging portion is engaged with the engaged portion, the tightening portion is closed to tighten the bar member. At this time, since a plurality of engaging portions are arranged in the circumferential direction, by changing the engaging portion with which the engaged portion engages, the circumferential length of the tightening portion is matched to the circumferential length of the rod-shaped member and securely tightened. be able to. Therefore, unlike the conventional example, the suspension hook, which is an integrally molded product made of a resin material, can be fixed to the rod-like member without combining a plurality of parts, so that the cost can be reduced.

In the second disclosure, a plurality of the engaged portions are formed so as to line up in the circumferential direction on the other side of the tightening portion in the circumferential direction.

According to this configuration, the plurality of engaging portions can be engaged with the plurality of engaged portions, so that the discontinuous portion of the tightening portion can be prevented from opening unexpectedly.

In the third disclosure, one circumferential side of the tightening portion is formed so as to be arranged so as to overlap the outer surface of the other circumferential side of the tightening portion, and the engaging portion is arranged on the one circumferential side of the tightening portion. The engaged portion is formed on the outer surface of the tightening portion on the other side in the circumferential direction, and is formed of a groove into which the teeth are fitted. .

According to this configuration, it is possible to firmly engage by fitting the teeth into the grooves. In addition, if a plurality of teeth are provided, it is possible to easily change the circumferential length of the tightening portion by fitting an arbitrary tooth into the groove.

In a fourth disclosure, the tightening portion is configured to be horizontally openable. That is, it is conceivable that the engaged portion cannot be engaged with the engaging portion, for example, when the diameter of the rod-like member is large and the circumferential length of the tightening portion is insufficient. In this case, if the bar-like member is inserted into the bar-shaped member after the bar-like member is opened after the bar-like member is opened in the horizontal direction, the upper part of the bar-like member can be hooked on the bar-like member, and the article can be prevented from falling off.

In the fifth disclosure, a first finger contact portion and a second finger contact portion are provided on one side and the other side of the tightening portion in the circumferential direction, respectively.

According to this configuration, the teeth can be engaged with the grooves by putting fingers on the first finger contact portion and the second finger contact portion and applying force in a direction in which they approach each other.

In the sixth disclosure, an upper inner surface of the tightening portion is formed with an upward recessed portion. That is, for example, it is assumed that the suspension hook is suspended from a string that is thinner than the rod-shaped member. In this case, the suspension hook can be hooked to the string by inserting the string into the recess.

In the seventh disclosure, since the width of the concave portion is narrowed toward the top of the concave portion, it becomes difficult for a string or the like to come off after being caught in the concave portion.

In an eighth disclosure, a drug carrier that holds a drug to evaporate and a container that accommodates the drug carrier are provided, and the drug is diffused to the outside from a drug release opening formed in the container. It is possible to presuppose a drug diffuser including a configured drug diffuser main body and a suspension member for allowing the drug diffuser main body to be suspended from a rod-shaped member extending in a substantially horizontal direction. The hanging member includes a tightening portion that surrounds the rod-like member in the circumferential direction and that is partially discontinuous in the circumferential direction so as to be openable. In addition, a plurality of engaging portions are formed so as to be arranged in the circumferential direction on one side of the tightening portion in the circumferential direction, and a to-be-engaged portion that engages with the engaging portion is formed on the other side of the tightening portion in the circumferential direction. part is formed.

According to this configuration, the medicine diffuser main body can be hung from the rod-shaped member by the hanging member having the same effects as those of the first disclosure.

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

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail based on the drawings. It should be noted that the following description of preferred embodiments is essentially merely illustrative, and is not intended to limit the invention, its applications, or its uses.

FIG. 1 shows a drug diffuser 1 according to an embodiment of the 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 holder 11 holding a drug to evaporate and a container 20 for accommodating the drug holder 11. The container 20 has an opening 21a for drug diffusion and an opening 21a. It is configured to diffuse the drug out of the container 20 from the portion 22a (shown in FIG. 3). The hanging member 40 is detachably provided with respect to the medicine diffuser main body 10 .

In the description of this embodiment, the front side of the drug diffuser 1 in use is the front side, the back side is the rear side, and the left side of the drug diffuser 1 when viewed from the front is the left side of the drug diffuser 1 in use. , and the right side is the right side of the drug diffuser 1 . Therefore, the width direction of the medicine diffuser 1 is the horizontal direction. This directional definition is for convenience of explanation only and either side may be right in actual use. Also, with respect to the front-rear direction, either side may face forward during use. In addition, since the container 20 of this embodiment turns around a vertical line, the front and back or left and right may be interchanged during use.

Although it is preferable to use the drug diffuser 1 in a windy place, it can also be used in almost no wind. When used in a place where the wind blows, it is preferable to arrange the drug diffuser 1 so that the wind blows from the front side of the drug diffuser 1. In this embodiment, the front side of the drug diffuser 1 is the upstream side in the air flow direction. , the rear side of the drug diffuser 1 is defined as the downstream side in the direction of air flow. Since the direction of the wind is not always constant under natural conditions, the wind may hit from the front side of the drug diffuser 1, or it may hit from the rear side or left and right sides. Because it is hit by a natural wind, its force can be strong or weak.

(Structure of drug carrier 11)
The drug carrier 11 can be made of, for example, a cloth material such as a nonwoven fabric, a net-like member, a sponge-like member, or the like, and has air permeability in the thickness direction (front and back direction). The drug carrier 11 may have, for example, a flat shape, or may have a shape formed by bending to form a pleat shape. Further, the outer shape of the drug carrier 11 may be polygonal such as rectangular or triangular, or may be circular or elliptical. A plurality of drug holders 11 can also be accommodated in one container 20 . In this case, a plurality of drug holders 11 may be stacked in the thickness direction, or arranged in the vertical direction or the horizontal direction.

In this embodiment, the drug carrier 11 has a mesh shape and is thin in the airflow direction. In the case of the drug carrier 1 that is folded to form a pleated shape, the direction in which the crests and troughs of the pleats continue can be the left-right direction (width direction) of the container 20 . The drug carrier 11 is impregnated with a drug that gradually volatilizes at normal temperature (normal temperature volatility).

Volatility at normal temperature means the property of volatilizing in the air at normal temperature (for example, 25°C). The type of this agent is not particularly limited, but examples include insect repellents, insecticides, deodorants, disinfectants, fragrances, antiviral agents (virus deactivators), and the like. Only seeds may be used, or two or more may be used in combination. Specifically, examples of insecticides composed of pyrethroid compounds include transfluthrin, metofruthrin, and the like. These pyrethroid compounds have various optical isomers or geometric isomers. isomers can also be used, and not only can they be used alone, but also two or more kinds can be used in combination. Further, the drug may be an ester compound or the like. Further, the drug may be DEET (N,N-diethyl-3-methylbenzamide), Icaridine (1-methylpropyl 2-(2-hydroxyethyl)-1-piperidinecarboxylate), and the like. It is also possible to use a mixture of two or more of the above agents.

The drug may contain a solvent that dissolves the insecticidal or insect repellent ingredients. In addition, the drug may contain a synergist. In addition, the drug may contain antibacterial agents such as hinokitiol, tetrahydrolinalool, eugenol, citronellal, and allyl isothiocyanate. In addition, the chemical may contain an antifungal agent such as isopropylmethylphenol, orthophenylphenol, or the like. In addition, drugs include citronella oil, orange oil, lemon oil, lime oil, yuzu oil, lavender oil, peppermint oil, eucalyptus oil, jasmine oil, hiba oil, cypress oil, bamboo extract, mugwort extract, paulownia oil, and green tea essential oil. , limonene and other aromatic agents and deodorants may be contained.

The drug can be impregnated into the drug carrier 11 . The volatilization amount of the chemical can be set to about 0.01 to 0.6 mg per hour when the air temperature is 25° C. and the flow rate of the air blown onto the chemical holder 11 is 0.1 to 1.5 m/sec. Yes, but this is an example and may be outside this range. The volatilization amount of the chemical can be changed by the type of solvent, the structure, size and surface area of the chemical holding body 11, the material constituting the chemical holding body 11, the basis weight, and the like.

In addition, the drug can be adhered to the drug carrier 11 by coating or spraying, and the drug can also be held by the drug carrier 11 in this way. The drug can also be held in the drug carrier 11 by kneading the drug into the material forming the drug carrier 11 . Any method may be used to hold the drug in the drug holder 11 .

(Configuration of container 20)
As shown in FIGS. 2 to 4, the container 20 has a vertically elongated shape in which the vertical dimension is longer than the width dimension as a whole. The thickness of the container 20 is set shorter than the dimension in the width direction, so that the container 20 has a thick plate shape. The drug holder 11 is accommodated in the container 20 in a vertically extending posture.

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

Since the container 20 is substantially S-shaped in plan view in this way, the container 20 is susceptible to wind blowing from any direction. Then, if the wind speed is equal to or higher than a certain wind speed, the container 20 is swirled around the vertical line by the received wind. By swirling with the wind in this way, the drug contained in the drug holding body 11 can be efficiently diffused around.

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, the right end of the container 20 is provided with a right protruding plate portion 20b that protrudes forward and extends in the vertical direction. The left projecting plate portion 20a and the right projecting plate portion 20b are portions that receive the wind. This allows the container 20 to receive the wind more efficiently, allowing the container 20 to swirl even at lower wind speeds. The left projecting plate portion 20a and the right projecting plate portion 20b may be omitted.

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 side member 21 and the rear side member 22 can be maintained in an integrated state by a well-known joining method such as a method using engaging claws or a welding method. Incidentally, the container 20 may be composed of one member, or may be composed of three or more members.

The front side member 21 and the rear side member 22 are made of a hard resin material such as polyethylene terephthalate (PET) or polypropylene. It is a material. The front member 21 and the rear member 22 may be made of the same material, or may be made of different materials.

In addition, the plurality of rear lower end fins 22d are arranged in the vicinity of the lower end of the rear frame portion 22b at intervals in the left-right direction. It is composed of an inclined plate inclined with respect to the virtual line C as shown in FIG. The plurality of rear center fins 22e are arranged in the vertical middle portion of the rear frame portion 22b so as to be spaced apart from each other in the left-right direction. is composed of an inclined plate inclined with respect to the imaginary line C. That is, the rear upper end fin 22c, the rear lower end fin 22d, and the rear central fin 22e are inclined in the same direction with respect to the virtual line C. As shown in FIG.

The plurality of rear upper intermediate fins 22f are arranged at intervals in the left-right direction between the rear upper end fin 22c and the rear central fin 22e. It consists of a slanted plate that is slanted with respect to the In addition, the plurality of rear lower intermediate fins 22g are arranged at intervals in the left-right direction between the rear central fin 22e and the rear lower end fin 22d. It is composed of an inclined plate inclined with respect to the imaginary line C so as to be positioned to the left as it goes further. That is, the rear upper intermediate fin 22f and the rear lower intermediate fin 22g are inclined in the same direction with respect to the virtual line C. As shown in FIG.

The vertical dimension of the rear central fin 22e, the vertical dimension of the rear upper intermediate fin 22f, and the vertical dimension of the rear lower intermediate fin 22g are substantially the same.

Fins 21c to 21g on the front side and fins 22c to 22g on the rear side are arranged so that the front side and the rear side are positioned at the same height. That is, the front upper end fin 21c and the rear upper end fin 21c are arranged at the same height, have the same vertical dimension, and overlap each other when viewed along the imaginary line C. do. The front lower end fins 21d and the rear lower end fins 22d are arranged at the same height, have the same vertical dimension, and overlap each other when viewed along the imaginary line C. do. In addition, the front central fin 21e and the rear central fin 22e are arranged at the same height, have the same vertical dimension, and overlap each other when viewed along the imaginary line C. do. Also, the front upper intermediate fin 21f and the rear upper intermediate fin 22f are arranged at the same height, and the vertical dimension is set to be the same. overlap each other. Furthermore, the front side lower intermediate fin 21g and the rear side lower intermediate fin 22g are arranged at the same height, and the vertical dimensions are set to be the same. overlap each other.

The fins 21c to 21g on the front side and the fins 22c to 22g on the rear side may all have the same or different dimensions in the ventilation direction. 7A and 7B, the dimensions of the fins 21c to 21g and 22c to 22g positioned at the ends in the left-right direction It may be set shorter than the dimensions of 21g and 22c to 22g in the ventilation direction.

The inclination angles of the fins 21c to 21g and 22c to 22g with respect to the virtual line C can be set, for example, within a range of 10° or more and 80° or less. The larger the inclination angle, the higher the air guiding effect of the fins 21c to 21g and 22c to 22g, which is preferable. On the other hand, when the angle of inclination exceeds 80°, the openings 21a and 22a are almost blocked by the fins 21c to 21g and 22c to 22g, and the ventilation resistance rises sharply, reducing the amount of drug to be diffused. Therefore, it is preferable to set the inclination angle of the fins 21c to 21g and 22c to 22g with respect to the virtual line C to 80° or less. Further, if the angle of inclination of the fins 21c to 21g and 22c to 22g with respect to the imaginary line C is less than 10°, the effect of guiding the weak wind in the left and right direction is suddenly reduced. The angle of inclination of 22c-22g with respect to imaginary line C is preferably 10° or more. Further, although not shown, fins for guiding the wind in the vertical direction may be provided.
(Effect of fins)
As described above, the container 20 is swirled around the vertical line by being subjected to wind having a certain wind speed or more, and thereby the medicine can be efficiently diffused around. On the other hand, when the wind speed is less than a certain value, the container 20 hardly swirls, so that the swirling effect of diffusing the drug cannot be expected. However, even in that case, the container 20 of the present embodiment has the fins 21c to 21g and 22c to 22g, so that the medicine can be diffused around. This point will be described below.

The dashed lines in FIGS. 7A and 7B indicate the flow of wind blowing from the front of the container 20, which is weak enough to prevent the container 20 from swirling. The wind blowing from the front passes through the drug-impregnated body 11 while being guided by the front upper intermediate fins 21f and the front lower intermediate fins 21g, as partially shown in FIG. 7A. The wind passing through the drug-impregnated body 11 volatilizes the drug. Then, the air containing the medicine is guided rightward by the rear upper intermediate fins 22f and the rear lower intermediate fins 22g.

7B, the wind blowing from the front passes through the drug-impregnated body 11 while being guided by the front upper end fin 21c, the front lower end fin 21d, and the front center fin 21e. Wind passing through the drug-impregnated body volatilizes the drug. Then, the air containing the medicine is guided leftward by the rear upper end fin 22c, the rear lower end fin 22d, and the rear central fin 22e.

As described above, the drug laden wind is guided by the rear fins 22c-22g and emitted from the rear side of the container 20 in a left and right distributed manner. In this way, the air containing the drug can be dispersed and discharged to the left and right, so that the drug can be diffused well even if the container 20 does not swivel.

Conversely, the same applies when the wind blows from the back of the container 20 . 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 fins 22c to 22g on the rear side, and then dispersed to the left and right by the fins 21c to 21g on the front side. 20 is emitted from the front. As described above, according to the configuration of this embodiment, the medicine can be diffused to the surroundings regardless of whether the wind blows from the front or from the back.

By the way, the wind does not necessarily come from the front or the back, but it can also be considered to come from the left and right. When the wind blows from the right and left sides of the container 20, the wind flows almost parallel to the drug-impregnated body 11, so the wind does not pass through the drug-impregnated body 11 as it is, and volatilization of the drug is expected. Can not. However, according to the present embodiment, even if wind blows from the left and right, the medicine can be diffused satisfactorily. This point will be described below.

The dashed line in FIG. 8A indicates the flow of the wind blowing from the left side of the container 20, which is weak enough to prevent the container 20 from turning. As partly shown in FIG. 8A, the wind blowing from the left side is received by the rear upper fin 22c, the rear lower fin 22d, and the rear center fin 22e on the rear side of the container 20, and the medicine inside the container 20 is It is guided towards the impregnation body 11 . The wind thus guided passes through the drug-impregnated body 11 to volatilize the drug. Then, the air containing the medicine flows out from the front side of the container 20 while being guided by the front upper end fin 21c, the front lower end fin 21d and the front central fin 21e.

The dashed line in FIG. 8B indicates the flow of the wind blowing from the right side of the container 20, which is weak enough to prevent the container 20 from turning. 8B, the wind blowing from the right side is received by the front upper fin 21c, front lower fin 21d, and front center fin 21e on the front side of the container 20, and the drug-impregnated body 11 inside the container 20 is received. be guided towards. The wind thus guided passes through the drug-impregnated body 11 to volatilize the drug. Then, the air containing the drug flows out from the back side of the container 20 while being guided by the rear upper end fin 22c, the rear lower end fin 22d and the rear central fin 22e.

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

In this way, even if the container 20 does not swirl, the medicine can be diffused in the surroundings regardless of which direction the wind blows.
Note that the above description is based on the assumption that the container 20 of this embodiment is configured to be swirled by the wind, so the description is limited to when the wind is weak (when the container 20 does not swirl). In this case, when the wind is strong, the swirling of the container 20 spreads the medicine. However, when the container 20 is fixed so as not to swirl, the fins 21c to 21g and 22c to 22g can of course provide a diffusion effect even in strong winds. In other words, the effects of the fins 21c-21g and 22c-22g are not limited to the case where the container 20 is configured to rotate, but are effective even when the container 20 is fixed so as not to rotate.

That is, the container 20 includes a front upper intermediate fin 21f and a front lower intermediate fin 21g that guide the wind introduced from the front opening 21a rightward (first direction), a rear upper intermediate fin 22f, and a front lower intermediate fin 21g. A rear lower intermediate fin 22g (first guide portion) is provided, 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 (second direction opposite to the first direction). , a rear upper end fin 22c, a rear lower end fin 22d, and a rear central fin 22e (second guide portion). The first guide portion 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 22f formed on the rear side of the container 20b. 22g. The second guide portion 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, a rear upper end fin 22c formed on the rear side of the container 20b, a rear It includes a side bottom fin 22d and a rear center fin 22e. The number of fins 21c to 21g and 22c to 22g is not limited to the illustrated number.

As shown in FIGS. 1 to 3, the container 20 has a front recess 21h (shown in FIG. 2) and a rear recess 22f (shown in FIG. ) are recessed toward the inside of the container 20 . The front-side concave portion 21h and the rear-side concave portion 22f are positioned at the central portion of the container 20 in the left-right direction. A turning center line D of the container 20 is positioned at a center portion in the left-right direction and a center portion in the front-rear direction of the container 20 , and the 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 vertically. The structure for connecting the hanging member 40 to the container 20 is not limited to the illustrated structure.

(Structure of suspension member 40)
As shown in FIGS. 2 and 3, the hanging member 40 is configured to swingably hang the container 20 as an article around a vertical line (rotating center line D). It has a sarkan 40B and a clip 40C. Sarkans 40B and clips 40C may be provided as required. It is also possible to turn the container 20 by omitting the salcan 40B and substituting a thread for the salcan 40B. Alternatively, the lower portion of the salcan 40B may be directly connected to the container 20 without providing the clip 40C.

For example, as shown in FIGS. 14A and 14B, the container 20 can be suspended from a rod-shaped member 100 extending substantially horizontally. can be called Further, although the details will be described later, as shown in FIG. 15, an article can be suspended from a large-diameter rod-shaped member 101 by a suspension hook 40A. Examples of the rod-shaped members 100 and 101 include clothes poles, various poles, and arms. The rod-shaped members 100 and 101 do not have to be installed strictly horizontally, and may be slightly inclined. Further, the container 20 can be hung on a string 102, as shown in FIG. The string 102 is, for example, a string used for drying clothes or other purposes, a rope, a rope, a rope, an elongated member, or the like, and is stretched horizontally. A suspension structure is configured by the suspension hook 40A and the monkey can 40B. The monkey can 40B is a connecting member for connecting the base member 52, which will be described later, to the container 20. As shown in FIG.

As shown in FIG. 1, one component of the suspension structure, Sarkan 40B, is a freely rotatable metal ring and is a well-known member in the prior art. Sarkan 40B is sometimes called a twister, and in this example, when the upper part of Sarkan 40B is stopped, the lower part can be easily rotated around a vertical line. That is, the upper part of the salcan 40B is connected to the lower part of the suspension hook 40A, while the lower part of the salcan 40B is connected to the clip 40C attached to the container 20. As shown in FIG. The clip 40</b>C is fixed to the container 20 by fitting into the front recess 21 h and the rear recess 22 f of the container 20 .

The suspension hook 40A has a tightening portion 41. As shown in FIG. The tightening portion 41 is composed of substantially the upper half of the hanging member 40, surrounds the rod-shaped members 100 and 101 in the circumferential direction, and is partially discontinuous in the circumferential direction so as to be openable. 41 is provided. As shown in FIG. 11 and the like, the tightening portion 41 has a generally C-shaped shape when the container 20 is not suspended.

In the description of this embodiment, as shown in Figs. direction is not limited. During use, the hanging hook 40A may be arranged so that the back side is on the front side of the container 20, or the hanging hook 40A may be arranged so that the right or left side is on the front side of the container 20. - 特許庁

As shown in FIG. 11, when the hanging hook 40A is viewed from the front or back, the tightening portion 41 is configured to be openable in the horizontal direction. Specifically, the discontinuous portion is located on the left side of the tightening portion 41 when the hanging hook 40A is viewed from the front. Therefore, the left side of the tightening portion 41 can be opened, and the upper left side (one side in the circumferential direction) 42 and the lower left side (the other side in the circumferential direction) 43 of the tightening portion 41 are vertically spaced apart from each other. be done. A discontinuous portion may be located on the right side of the tightening portion 41 .

The tightening portion 41 is made of a flexible resin material that has flexibility. Examples of such a resin material include polypropylene, but it is also possible to use other resin materials. The tightening portion 41 preferably has elasticity. Since the tightening part 41 has elasticity, even if the open part of the tightening part 41 is opened wide as shown in FIG. 14A, the shape is restored as shown in FIG. 11 by removing the force thereafter. be able to.

Since the tightening portion 41 has the properties (softness and flexibility) described above, as shown in FIGS. It is possible to transform into As a result, the rod-shaped members 100 and 101 can be put inside the tightening portion 41 . Alternatively, the left upper part 42 and the left lower part 43 may be deformed so that the distance between the left upper part 42 and the left lower part 43 is narrowed, and the left upper part 42 and the left lower part 43 may be arranged so as to radially overlap each other as shown in FIG. 14B. can. At this time, the left upper portion 42 overlaps the outer surface of the left lower portion 43 .

As shown in FIG. 11, a plurality of teeth 42a protruding radially inward from the inner surface of the left upper portion 42 of the tightening portion 41 are formed so as to be arranged in the circumferential direction. These teeth 42a constitute an engaging portion. All the teeth 42a have the same shape and are elongated in the front and back direction to secure a wide tooth surface. The interval between the teeth 42a can be set arbitrarily. For example, the teeth 42a may be adjacent to each other, or a gap may be formed between the teeth 42a.

A plurality of grooves 43a extending in the front and back direction are formed in the outer surface of the left lower portion 43 of the tightening portion 41 so as to be arranged in the circumferential direction. These grooves 43a constitute engaged portions that engage with the teeth 42a. The interval between adjacent teeth 42a, 42a and the interval between adjacent grooves 43a, 43a are set to be the same. Thereby, as shown in FIG. 14B, multiple teeth 42a can be engaged with multiple grooves 43a at once. Engaging a plurality of teeth 42a with a plurality of grooves 43a at once is preferable because the bonding strength between the left lower portion 42 and the left lower portion 43 increases. Note that one tooth 42a may be engaged with one groove 43a. Further, although not shown, teeth may be formed on the left lower portion 43 and grooves may be formed on the left upper portion 42 . Also, protrusions or protrusions may be formed instead of teeth, and recesses or the like may be formed instead of grooves.

By deforming the tightening portion 41 so as to narrow the distance between the upper left portion 42 and the lower left portion 43 and 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. teeth 42a can be engaged with many grooves 43a. In this embodiment, the interval between adjacent teeth 42a and 42a and the interval between adjacent grooves 43a and 43a are narrowly set to, for example, 0.5 mm or more and 2.0 mm or less, so that the diameter of tightening portion 41 can be finely adjusted. . Further, the adjustment range of the diameter of the tightening portion 41 can be set by the formation range of the teeth 42a in the circumferential direction and the formation range of the grooves 43a in the circumferential direction. The adjustment range of the diameter of the tightening portion 41 can be, for example, 5 mm or more and 30 mm or less.

(Action of tightening part)
With the above configuration, when the container 20 is hung from the rod-shaped member 100, as shown in FIG. be able to. As a result, the hanging hook 40A is fixed to the rod-shaped member 100, so that even if a strong wind blows and the container 20 is shaken by the wind, the medicine diffuser 1 does not move in the longitudinal direction of the rod-shaped member 100. can be prevented.

On the other hand, as shown in FIG. 15, assuming a case where the container 20 is hung from a large-diameter rod-shaped member 101, the left upper portion 42 and the left lower portion 43 cannot be overlapped in the radial direction, and the tightening portion 41 remains open. can be. In this case, the tooth 42a and the groove 43a cannot be engaged. However, even in this case, the bar member 101 can be tightened by the tightening portion 41 .

That is, in this case, since the tightening portion 41 is in a more open state than the state in which no force is applied (FIG. 11), the elastic force of the tightening portion 41 generates a force to close the tightening portion 41 . Due to this elastic force, the rod-shaped member 101 can be vertically sandwiched between the upper portion and the lower portion, and the rod-shaped member 101 can be tightened. As a result, even when the container 20 is hung from the large-diameter rod-shaped member 101, the suspension hook 40A can be fixed to the rod-shaped member 101. Therefore, even when the wind is strong, the medicine diffuser 1 is suspended from the rod-shaped member 101. can be prevented from moving in the longitudinal direction.

An upper finger contact portion (first finger contact portion) 42 b is provided on the outer surface of the left upper portion 42 of the tightening portion 41 with which a finger is placed when tightening the tightening portion 41 . In addition, a lower finger contact portion (second finger contact portion) 43b is provided on the outer surface of the left lower portion 43 of the tightening portion 41 with which a finger is placed when tightening the tightening portion 41 . The upper finger contact portion 42b is positioned directly above the portion where the teeth 42a are formed, and has a plate-like shape extending in the left-right direction and front-back direction. The user can place or keep his or her finger on the upper surface of the upper finger contact portion 42b. On the other hand, the lower finger contact portion 43b is positioned below the lowest groove 43a and has a plate-like shape extending in the left-right direction and front-back direction. The user can keep a finger on the lower surface of the lower finger contact portion 43b.

The upper finger contact portion 42b and the lower finger contact portion 43b are arranged such that at least a portion of the upper finger contact portion 42b overlaps with at least a portion of the lower finger contact portion 43b when viewed from the vertical direction. Shape and position are set. In addition, the upper surface of the upper finger contact portion 42b and the lower surface of the lower finger contact portion 43b are provided with an anti-slip uneven shape, textured shape, narrow grooves, and the like.

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 so that the thumb and the index finger are brought closer to each other, the left lower portion 42 and the left lower portion 43 approach each other, and are arranged so that the inner surface of the left lower portion 43 overlaps the outer surface of the left lower portion 42 . Thereby, the teeth 42a and the grooves 43a can be engaged. When the applied force is increased, as shown in FIG. 14B, the rod-shaped member 100 can be tightened by the tightening portion 41 by reducing the diameter of the tightening portion 41. In this state, the tooth 42a and the groove 43a are engaged to tighten. The tightened state by the portion 41 can be maintained.

A projecting portion 42c curved radially outward is formed at the lower portion of the left upper portion 42 of the tightening portion 41. As shown in FIG. A leading end portion of the projecting portion 42 c in the projecting direction is located radially outward of the left lower portion 43 . For example, as shown in FIG. 14A , when inserting the rod-shaped member 100 inside the tightening portion 41 , the rod-shaped member 100 can be brought into contact with the lower surface of the projecting portion 42 c and guided inside the tightening portion 41 . 11 is brought into the closed state shown in FIG. 14B, the upper end portion of the left lower portion 43 contacts the lower surface of the projecting portion 42c, thereby causing the left lower portion 43 to close to the left upper portion 42. can lead inside Furthermore, when the tightening portion 41 is opened, the protrusion 42c is lifted upward from the closed state of the tightening portion 41, thereby releasing the engagement between the teeth 42a and the grooves 43a, thereby facilitating the opening of the tightening portion 41. Can be opened easily. As a result, the medicine diffuser 1 can be removed from the rod-shaped member 100 .

The upper portion of the tightening portion 41 is provided with a bent portion 44 bent so as to protrude upward at the central portion in the left-right direction. The bent portion 44 has a dimension in the left-right direction that becomes shorter as it approaches the upper end of the bent portion 44, and has a shape that is pointed upward when viewed from the front and back directions. Due to the formation of the bent portion 44 , a concave portion 44 a that is recessed upward is formed on the inner surface of the upper side of the tightening portion 41 . The width (dimension in the circumferential direction) of the recess 44a becomes narrower toward the top of the recess 44a. As shown in FIG. 16, when hanging from a string 102, the string 102 enters the concave portion 44a and is hooked. This stabilizes the hanging member 40 .

Since the bent portion 44 is formed, when the tightening portion 41 is opened, the bent portion 44 is elastically deformed so that the tightening portion 41 is opened. In addition, since the bent portion 44 functions like a spring, the springiness of the tightening portion 41 can be enhanced.

A lower projecting portion 45 projecting downward is provided at the lower portion of the tightening portion 41 . An indicator 50 , which will be described later, is provided below the lower projecting portion 45 . Further, the outer surface of the tightening portion 41 is provided with an upper rib 46 and side ribs 47 protruding radially outward. The upper rib 46 extends from the outer surface of the bent portion 44 to the upper finger contact portion 42b. Also, the side ribs 47 extend from the outer surface of the bent portion 44 to the lower projecting portion 45 . By forming the upper rib 46 and the side ribs 47, the strength of the tightening portion 41 can be increased to prevent it from falling when suspended from a large-diameter rod-shaped member 101 as shown in FIG. 15, for example. The upper ribs 46 and the side ribs 47 may be provided as required, and may be omitted.

(Configuration of indicator 50)
The indicator 50 is a dial-type indicator provided to indicate the timing at which the drug retained in the drug-impregnated body 11 becomes ineffective. The indicator 50 is provided on the hanging hook 40A as described above. In the conventional drug diffuser, the indicator is provided on the container, which imposes various restrictions on the shape of the container. In particular, in the case of a dial-type indicator 50, it may be desirable to set a large dial 51 in order to improve visibility. Volatilization efficiency may decrease. In this embodiment, the indicator 50 is arranged on the hanging hook 40A instead of the container 20, so that the opening area of the container 20 is not reduced. Moreover, since the shape of the container 20 is not restricted by the indicator, for example, the container 20 can be curved in an S shape in plan view as in the present embodiment.

Since the indicator 50 is provided below the lower projecting portion 45 projecting downward from the tightening portion 41 , the indicator 50 is arranged below the tightening portion 41 . That is, since the indicator 50 is arranged below the tightening portion 41 and not in the tightening portion 41 , the indicator 50 does not hinder the flexibility of the tightening portion 41 . As a result, when suspending the suspension hook 40A from the bar members 100 and 101, the fastening portion 41 can be easily deformed and suspended.

The indicator 50 includes a dial 51 displaying a plurality of numbers, a base member 52 rotatably supporting the dial 51, and a cover portion 53 formed to cover at least part of the surface of the dial 51. It is a dial-type indicator that can display desired information by rotating a dial 51 . As described above, the indicator 50 of the present embodiment is for displaying, as an example of desired information, the timing at which the drug retained in the drug retainer 11 becomes ineffective, and is also called a termination indicator. can. The indicator 50 can also display the start time of use of the medicine diffuser 1 as an example of desired information, and in this case, can be called a start time display device. By displaying the start time of use of the medicine diffuser 1, the end period can be grasped.

As shown in FIGS. 12A and 12B, the dial 51 is in the shape of a circular plate, for example, 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 is formed in the central portion of the dial 51 so as to penetrate in the front and back directions. The through hole 51a is circular because it is a hole for enabling the dial 51 to rotate. The centerline of the through-hole 51a becomes the rotation centerline of the dial 51. As shown in FIG.

A plurality of numbers are displayed on the surface 51b of the dial 51 so as to be arranged in the circumferential direction. The numbers displayed here indicate the "month" and are 1 to 12, but this is an example, and the year, characters, and symbols may be displayed. Also, the same numbers as those displayed on the front surface 51b are displayed on the rear surface 51c of the dial 51 as well. The numbers on the front surface 51b of the dial 51 and the numbers on the back surface 51b coincide in the circumferential direction. A front surface 51b and a rear surface 51c of the dial 51 are display surfaces for displaying the timing at which the medicine becomes ineffective. Only one of the surface 51b and the rear surface 51c of the dial 51 may display numbers.

The dial 51 is formed with a cylindrical peripheral wall portion 51d that protrudes from the peripheral portion of the through hole 51a to the back side 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 back 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 portion of the peripheral wall portion 51db in the circumferential direction is interrupted, and the convex portion 51e is arranged so as to correspond to the interrupted portion.

The base member 52 is arranged on the back side of the dial 51 and is a part that rotatably supports the dial 51 . The base member 52 has a substantially circular plate shape extending vertically and horizontally along the back side of the dial 51, and can therefore be called a support plate. The lower part of the lower protruding part 45 of the tightening part 41 is integrally formed with the upper part of the base member 52 . A connecting plate portion 54 that protrudes downward is provided at the lower portion of the base member 52 . An upper portion of the sarkan 40B for connecting with the container 20 is attached to the lower portion of the connecting plate portion 54. As shown in FIG.

As shown in FIG. 10, the back surface of the base member 52 is provided with two back surface mark portions 52a, 52a for matching numbers on the dial 51. As shown in FIG. The back side mark portion 52a can be composed of, for example, an arrow, a symbol, a line segment, a character, etc. In this embodiment, it is composed of a line segment of a predetermined length extending in the radial direction. One back side mark portion 52a indicates the start time, and the other back side mark portion 52a indicates the end time. For example, when the use is started from January, the "1" on the rear surface 51c of the dial 51 is aligned with one of the rear surface mark portions 52a. Then, the other back side mark portion 52a indicates "9". In other words, when the usage period is assumed to be 9 months, both the back side mark portions 52a, A relative position of 52a is set. The relative positions of the back side mark portions 52a, 52a can be set arbitrarily. Further, for example, when one year is assumed as the period of use, only one rear side mark portion 52a is required.

The cover portion 53 is a portion arranged on the front side of the dial 51, covers the radially inner region of the surface 51b of the dial 51, and covers the radially outer region (the region where the numbers are displayed). configured to be exposed. The cover portion 53 has a circular plate shape similar to the base member 52 . The surface of the cover portion 53 is provided with two front-side mark portions 53a, 53a for matching numbers on the dial 51. As shown in FIG. The front side mark portion 53a is for indicating the start and end times, like the back side mark portion 52a.

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

12A and 12B show shapes of the tightening portion 41, the lower projecting portion 45, the base member 52, the cover member 53, the connecting plate portion 54, and the thin hinge 55 immediately after molding. As shown in these figures, the tightening portion 41, the lower projecting portion 45, the base member 52, the cover member 53, the connecting plate portion 54, and the thin hinge 55 are integrally formed of the same resin material. Immediately after molding, the thin hinge 55 is opened, that is, the base member 52 and the cover member 53 are in an unfolded state. In the unfolded state, the suspension hook 40A, the base member 52, and the cover member 53 pass through substantially the same plane and are arranged so as to virtually form the plane. That is, when the suspension hook 40A, the base member 52, and the cover member 53 are integrally molded, if the suspension hook 40A, the base member 52, and the cover member 53 are largely deviated from the same plane, the mold is deep. There is a concern that the difference between the part and the shallow part will become large, the mold structure will become complicated, and molding defects will easily occur. On the other hand, 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 can be simplified. In addition, the moldability is improved, and the cost can be further reduced.

On the front surface of the base member 52, three base-side columnar portions 52b which are inserted into the through holes 51a of the dial 51 and rotatably support the dial 15 are formed at intervals in the circumferential direction. . The base-side columnar portions 52b extend in the front-rear direction, and the three base-side columnar portions 52b constitute one support shaft for supporting the dial 51. As shown in FIG. In other words, the three base-side columnar portions 52b are spaced apart from each other in the circumferential direction of the support shaft. The number of base-side columnar portions 52b is not limited to three, and may be two or less, or may be four or more.

The outer surfaces of the three base-side columnar portions 52b are arcuate surfaces located on the same circumference, and are formed so as to be in sliding contact with the inner peripheral surface of the through hole 51a of the dial 51. As shown in FIG. When the dial 51 is rotated, the inner peripheral surface of the through hole 51a slides on the outer surfaces of the three base-side columnar portions 52b, thereby allowing the dial 51 to rotate smoothly.

On the other hand, on the back surface of the cover portion 53, a cover-side columnar portion 53b is formed which is inserted between the base-side columnar portions 52b and coupled to the base-side columnar portions 52b. The cover-side columnar portion 53b is formed in a triangular tubular shape, and is joined to the inner surfaces of the three base-side columnar portions 52b by fitting inside the three base-side columnar portions 52b. For example, engaging claws or the like may 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 them. The shape of the cover-side columnar portion 53b is not limited to a triangular tubular shape, and may be any shape as long as it fits with the base-side columnar portion 52b to obtain a rotation-preventing effect. may

The cover-side columnar portion 53b has a triangular tubular shape, and the three base-side columnar portions 52b are arranged on the outer surface of the columnar portion 53b and coupled to each other. Relative rotation around is prevented. In other words, the cover-side columnar portion 53b and the base-side columnar portion 52b constitute a detent structure that prevents the base member 52 and the cover portion 53 from rotating relative to each other, and the indicator 50 has the detent structure. I have. As a result, even if the thin hinge 55 breaks, for example, the base member 52 and the cover portion 53 do not rotate relative to each other, and the starting and ending times of the front and back sides are maintained correctly.

A specific example of the anti-rotation structure will be described. In this embodiment, three apexes 53c of the cover-side columnar portions 53b are arranged between adjacent base-side columnar portions 52b in the circumferential direction. Then, when one of the base member 52 and the cover portion 53 tries to rotate relative to the other, the top portion 53c hits the base-side columnar portion 52b, thereby preventing the relative rotation. The top portion 53c is a stopper portion.

An annular wall 52 e is formed on the peripheral edge of the base member 52 . The annular wall 52 e protrudes toward the front side and extends annularly around the rotation center line of the dial 51 . The radial center portion of the annular wall 52e and the rotation centerline of the dial 51 are aligned. A large number of engaging protrusions 52f are arranged in the circumferential direction on the inner peripheral surface of the annular wall 52e. 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 contacts the engaging projection 52f in the annular wall 52e. placed in When the convex portion 51e and the engaging projection 52f come into contact with each other and become engaged, the dial 51 becomes difficult to rotate, and unexpected rotation is prevented. On the other hand, when the dial 51 is intentionally rotated with a finger, the convex portion 51e is elastically deformed and disengaged from the engaging projection 52f, allowing the dial 51 to rotate.

(When using drug diffuser 1)
The drug diffuser 1 configured as described above can be used outdoors by being hung from rod-shaped members 100 and 101 as shown in FIGS. can be used When a natural wind hits the container 20 in the suspended state, if the force of the wind is strong, the suspension member 40 is provided with the monkey can 40B, so the container 20 turns. The stronger the force of the wind, the faster the vessel 20 swirls. This allows efficient diffusion of the drug.

On the other hand, when the wind is light, the container 20 may not swirl, but as described above, the drug diffuser 1 of the present embodiment can effectively diffuse the drug even when it does not swirl.

(Efficacy test in light wind)
Therefore, the effectiveness test in light wind will be described. The test under light wind conditions was carried out in an 8-tatami mat windless constant temperature room with ventilation conditions of 5 times per hour. At a distance of 0.1 m from the wall of the test chamber, test insects are placed at three heights of 0.5 m, 1.0 m, and 2.0 m, parallel to the wall, at 90 cm intervals in the horizontal direction. I hung an insect net containing In other words, 3×3=9 insect nets were installed vertically and horizontally. The test insect is a female Culex pipiens. The drug impregnated in the drug-impregnated body 11 is an insecticide made of a pyrethroid compound. The chemical diffuser 1 was suspended at a height of 1 m at a distance of 1.1 m in front of the insect net on the left end (1.2 m from the wall), and the wind speed near the front of the container 20 was set to 0.00 by an electric fan. The container 20 was blown with air at 5 m/sec. At this wind speed, the container 20 of the present embodiment hardly turns. After the insect net was installed, the chemical diffuser 1 was installed, and after the chemical diffuser 1 was installed, the number of knockdown insects over time was observed. The test was repeated three times, and the KT50 value was obtained from the knockdown rate at each observation time by Bliss' Probit method.

As a result, the KT50 value (min) was 9.12 to 10.32 for the test insects placed at a distance from the chemical diffuser 1, and sufficient efficacy of the chemical was obtained. In addition, the KT50 value (min) was 4.54 to 6.37 for the test insects placed near the drug diffuser 1, indicating that the efficacy of the drug was even higher.

Next, as a comparative example, a container without the fins 21c to 21g and 22c to 22g (described in JP-A-2011-19507) was prepared and the same test was conducted. As a result, the KT50 value (min) was 11.33 to 12.93 for the test insects placed at a distance from the chemical diffuser of the comparative example, and the knockdown time was longer than that of the example. was found to take In addition, the KT50 values (min) for the test insects placed near the drug diffuser of the comparative example were 4.71 to 6.92, equivalent to or higher than those of the example. I knew it would take me a while to get down.

As described above, it was confirmed that the drug diffuser 1 of the present example had an effect equal to or greater than that of the drug diffuser of the comparative example when the wind was light (when the container did not swirl). In particular, it was confirmed that the drug diffuser 1 of the present example exhibited a marked improvement in efficacy compared to the comparative example, at a position distant from the drug diffuser. This indicates that the drug diffuser 1 of the present embodiment can diffuse the drug over a wider range in light wind.

The reason why the effect is high in light wind is that the fins 21c to 21g and 22c to 22g are provided, as shown in FIGS. 7A and 7B, so that the medicine is guided to both the left and right sides and spreads over a wide range. In addition, the chemical can be diffused even when the wind blows from the left as shown in FIG. 8A and when the wind blows from the right as shown in FIG. 8B. high efficacy can be obtained.

(Action and effect of the embodiment)
As described above, according to this embodiment, a portion of the tightening portion 41 of the hanging hook 40A in the circumferential direction is discontinuous. By deforming the tightening portion 41 so as to open the portion, it becomes possible to put the rod-shaped member 100 inside the tightening portion 41 from the opened portion of the tightening portion 41 . Thereafter, as shown in FIG. 14B, when the teeth 42a are engaged with the grooves 43a, the tightening portion 41 is closed and the bar member 100 is tightened. At this time, since a plurality of teeth 42a are arranged in the circumferential direction, by changing the teeth 42a with which the grooves 43a are engaged, it is possible to match the circumferential length of the tightening portion 41 to the circumferential length of the rod-shaped member 100 and tighten it securely. can. Therefore, the hanging hook 40A, which is an integrally molded product made of a resin material, can be fixed to the rod-like member 100, so that the cost can be reduced.

Further, when the medicine diffuser main body 10 is hung by the hanging hook 40A, air flows in and out of the openings 21a and 22a of the container 20, thereby diffusing the medicine to the outside. Moreover, since the indicator 50 is provided on the hanging hook 40A, the opening area of the container 20 is not reduced, and the indicator 50 can be provided regardless of the shape of the container 20 .

Further, since the base member 52 and the cover portion 53 of the indicator 50 are integrally molded via the thin hinge 55, the number of parts is reduced. During assembly, the dial 51 is placed on the base member 52, and the thin hinge 55 is bent to place the cover member 53 on the front side of the dial 51, thereby obtaining the indicator 50 that rotatably supports the dial 51. , facilitating the assembly work.

The above-described embodiments are merely examples in all respects and should not be construed in a restrictive manner. Furthermore, all modifications and changes within the equivalent range of claims are within the scope of the present invention. The drug diffuser 1 can also be used without turning. For example, the hanging member 40 can be used to hang the container 20 from a doorknob (not shown) or the like.

In addition, the article to be hung by the hanging member 40 is not limited to the drug diffuser 1, and various other articles can be hung, and the hanging member 40 can be used as part of a clothes hanger, for example. .
