The present invention relates to a dial-type display device that displays the year, month, date, etc. using a dial, a hanging structure equipped with the dial-type display device, and a drug diffuser.

For example, Patent Document 1 discloses a dial-type display device for displaying the date. The dial-type display device in Patent Document 1 comprises a disk-shaped dial on which a date scale is displayed, a support plate that rotatably supports the center of the dial, and a cover formed to cover the dial. The cover is formed with a window through which the date scale on the dial can be seen, and the date can be displayed by rotating the dial to align any date scale with the window.

Patent documents 2 and 3 also disclose that a dial-type indicator is provided in the drug dispenser to show when the drug runs out.

Registered Utility Model No. 3008582 JP 2020-68735 A Design Registration No. 1444922

However, the dial-type display device described above requires at least three components: a dial, a base member that rotatably supports the dial, and a member that serves as a marker for adjusting the numbers on the dial, resulting in a large number of parts. Furthermore, since the dial needs to rotate smoothly relative to one another, high assembly and molding precision is required, and the assembly work becomes complicated, resulting in high costs.

The present invention was made in consideration of these points, and its purpose is to reduce the number of parts and ease the assembly work, thereby reducing costs, when displaying desired information by rotating a dial.

In order to achieve the above object, the first disclosure is premised on a dial-type display device that is configured to be able to display desired information by rotating a dial on which multiple numbers are displayed. The device is equipped with a base member that is disposed on the back side of the dial and rotatably supports the dial, and a cover portion that is disposed on the front side of the dial and is formed so as to cover at least a portion of the surface of the dial, and is integrally molded with the base member via a thin hinge.

With this configuration, the base member and the cover are integrally molded via a thin hinge, reducing the number of parts. During assembly, the dial is placed on the base member, and the thin hinge is folded to place the cover on the front side of the dial, resulting in a dial-type display device that rotatably supports the dial, making assembly easier.

In the second disclosure, a rotation prevention structure is provided that prevents the base member and the cover portion from rotating relatively around the center line of rotation of the dial, so that even if the thin hinge breaks, the base member and the cover portion are prevented from rotating relatively.

In the third disclosure, a through hole penetrating the center of the dial in the front-to-back direction is formed, the base member is formed with a plurality of base-side columnar parts spaced apart from one another in the circumferential direction and inserted into the through hole to rotatably support the dial, the cover part is formed with cover-side columnar parts inserted between the base-side columnar parts and coupled to the base-side columnar parts, and the anti-rotation structure is formed by the base-side columnar parts and the cover-side columnar parts.

According to this configuration, by inserting the cover side columnar part between the base side columnar parts and connecting them to the base side columnar parts, the cover part is fixed in a predetermined assembly position, and relative rotation between the cover part and the base member is prevented.

In the fourth disclosure, the base side columnar portions are spaced apart from one another in the circumferential direction, and the cover side columnar portion has a stopper portion disposed between adjacent base side columnar portions in the circumferential direction.

With this configuration, when the cover-side columnar portion is inserted between the base-side columnar portions, the stopper portion of the cover-side columnar portion is positioned between the base-side columnar portions adjacent in the circumferential direction, so that relative rotation between the cover portion and the base member is reliably prevented.

In the fifth disclosure, a dial-type display device configured to be able to display desired information by rotating a dial showing multiple numbers is provided on a hanging hook for hanging an object, and the dial-type display device is provided with a base member disposed on the back side of the dial, rotatably supporting the dial and integrally molded with the hanging hook, and a cover portion disposed on the front side of the dial, formed so as to cover at least a portion of the surface of the dial, and integrally molded with the base member via a thin hinge.

With this configuration, the hanging hook, base member, and cover are molded as a single unit, reducing the number of parts in the hanging structure with a dial display.

In the sixth disclosure, when the base member and the cover portion are deployed, the hanging hook, the base member, and the cover portion are arranged to form substantially the same plane.

In other words, if the hanging hook, base member, and cover part are significantly misaligned from the same plane when they are molded as a single unit, the difference between the deep and shallow parts of the mold will become large, complicating the mold structure and raising concerns that molding defects will be more likely to occur. In response to this, with this configuration, the mold structure when the hanging hook, base member, and cover part are molded as a single unit is simplified, moldability is improved, and costs can be further reduced.

In the seventh disclosure, in a drug diffuser comprising a drug holder that holds a drug to be evaporated and a container that houses the drug holder and is configured to diffuse the drug to the outside from an opening for drug diffusion formed in the container, a hanging member for hanging the drug diffuser body, and a dial-type display device configured to display desired information by rotating a dial on which a plurality of numbers are displayed, the dial-type display device comprises a base member that is arranged on the back side of the dial and rotatably supports the dial, and a cover portion that is arranged on the front side of the dial and is formed so as to cover at least a portion of the surface of the dial, and is integrally molded with the base member via a thin-walled hinge.

As explained above, the cover is integrally molded via a thin hinge to the base member that is located behind the dial and rotatably supports the dial, which reduces the number of parts and simplifies assembly, resulting in lower costs.

The following describes in detail an embodiment of the present invention with reference to the drawings. Note that the following description of the preferred embodiment is essentially merely an example and is not intended to limit the present invention, its applications, or its uses.

Figure 1 shows a drug diffuser 1 according to an embodiment of the present invention. The drug diffuser 1 comprises a drug diffuser body 10 and a hanging member 40 for hanging the drug diffuser body 10. The drug diffuser body 10 comprises a drug holder 11 that holds a drug to be evaporated and a container 20 that contains the drug holder 11, and is configured to diffuse the drug to the outside of the container 20 from openings 21a and 22a (shown in Figure 3) for drug diffusion formed in the container 20. The hanging member 40 is provided removably with respect to the drug diffuser 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 when the drug diffuser 1 in use is viewed from the front is the left side of the drug diffuser 1, and the right side is 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 direction is only for convenience of description, and either side may be the right when actually used. Also, with regard to the front-to-rear direction, either side may face forward when in use. Also, since the container 20 in this embodiment rotates around a vertical line, the front-to-rear and left-to-right directions may be reversed when in use.

The chemical diffuser 1 is preferably used in windy locations, but can also be used in almost windless locations. When used in windy locations, it is preferable to position the chemical diffuser 1 so that the wind hits the front side of the chemical diffuser 1; in this embodiment, the front side of the chemical diffuser 1 is the upstream side in the air flow direction, and the rear side of the chemical diffuser 1 is the downstream side in the air flow direction. Under natural conditions, the wind direction is not always constant, so the wind may hit the front side of the chemical diffuser 1, or it may hit the rear side or the left and right sides. As the natural wind hits, the force of the wind may be strong or weak.

(Configuration of drug support 11)
The drug holder 11 can be made of, for example, a cloth material such as a nonwoven fabric, a net-like material, a sponge-like material, etc., and has breathability in the thickness direction (front-back direction). The drug holder 11 may be, for example, flat, or be folded to form a pleated shape. The outer shape of the drug holder 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 holders 11 can be stored in one container 20. In this case, the plurality of drug holders 11 may be stored stacked in the thickness direction, or may be stored side by side in the vertical or horizontal directions.

In this embodiment, the drug holder 11 is mesh-like and thins in the direction of ventilation. In the case of a drug holder 1 that is folded to form pleats, the direction in which the peaks and valleys of the pleats continue can be the left-right direction (width direction) of the container 20. The drug holder 11 is impregnated with a drug that has the property of gradually volatilizing at room temperature (room temperature volatility).

Room temperature volatility refers to the property of volatilizing into the air at room temperature (e.g., 25°C), and examples of such agents include those with a vapor pressure of 0.001 Pa to 0.1 Pa at 25°C. The type of agent is not particularly limited, and examples include insect repellents, insecticides, deodorants, disinfectants, fragrances, and antiviral agents (virus inactivators). One of these may be used alone, or two or more may be used in combination. Specifically, examples of insecticides made of pyrethroid compounds include transfluthrin and metofluthrin. These pyrethroid compounds have various optical isomers or geometric isomers, and any of these isomers can be used, and they can be used alone or in combination of two or more. The agent may also be an ester compound, etc. The above-mentioned drug may be, for example, DEET (N,N-diethyl-3-methylbenzamide), Icaridin (2-(2-hydroxyethyl)-1-piperidine carboxylate 1-methylpropyl), etc. A mixture of the above-mentioned drugs may also be used.

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

The chemical can be impregnated into the chemical holder 11. The amount of chemical that volatilizes 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, but this is just one example and it may be outside this range. The amount of chemical that volatilizes can be changed by the type of solvent, the structure, size, surface area, material that makes up the chemical holder 11, basis weight, etc.

The drug can also be attached to the drug holder 11 by coating or spraying it, which also allows the drug to be held in the drug holder 11. The drug can also be held in the drug holder 11 by kneading the drug into the material that constitutes the drug holder 11. Any method can be used to hold the drug in the drug holder 11.

(Configuration of container 20)
2 to 4, the container 20 has an elongated shape with the vertical dimension being longer than the width dimension as a whole. The thickness of the container 20 is set to be shorter than the width dimension, so that the container 20 has a thick plate shape. The drug support 11 is accommodated in the container 20 in a position extending in the vertical direction.

As shown in FIG. 5, the container 20 has a shape close to an S letter in plan view. That is, in plan view of the container 20, it is gently curved so that it is positioned further forward as it approaches the left end from the center in the left-right direction, and is also gently curved so that it is positioned further back as it approaches the right end from the center in the left-right direction. The left and right parts of the container 20 are curved in opposite directions, and the left and right parts are integrated at the center in the left-right direction.

Since the container 20 is roughly S-shaped in a plan view, it can easily catch wind from any direction. If the wind is at or above a certain speed, the container 20 will rotate around a vertical line due to the wind it receives. By rotating in this way due to the wind, the drug contained in the drug holder 11 can be efficiently diffused to the surroundings.

The left end of the container 20 is provided with a left protruding plate portion 20a that protrudes forward and extends vertically. The right end of the container 20 is provided with a right protruding plate portion 20b that protrudes forward and extends vertically. The left protruding plate portion 20a and the right protruding plate portion 20b are the portions that receive the wind. This allows the container 20 to receive the wind more efficiently, and the container 20 can rotate even at lower wind speeds. The left protruding plate portion 20a and the right protruding 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 member 21 and the rear member 22 can be held in an integrated state by a known joining method, such as a method using an engaging claw or a welding method. The container 20 may be composed of one member, or three or more members.

The front member 21 and the rear member 22 are made of a hard resin material such as polyethylene terephthalate (PET) or polypropylene, and more specifically, are made of a material that is harder and less likely to deform than the materials that make up the drug holder 11. The front member 21 and the rear member 22 may be made of the same material or different materials.

As shown in Figs. 1 and 2, the front member 21 has a substantially rectangular front frame portion 21b. The open inner portion of the front frame portion 21b is an opening 21a for dispersing the drug. For example, when air flows into the container 20 from the opening 22a on the rear side, the air containing the drug flows out from the opening 21a. On the inner side of the front frame portion 21b, a front upper end fin 21c, a front lower end fin 21d, a front central fin 21e, a front upper intermediate fin 21f, and a front lower intermediate fin 21g are formed. The front upper end fin 21c, the front lower end fin 21d, the front central fin 21e, the front upper intermediate fin 21f, and the front lower intermediate fin 21g each extend in the vertical direction.

A plurality of front upper end fins 21c are arranged at intervals from each other in the left-right direction near the upper end of the front frame portion 21b, and are inclined so that they are located to the right as they move forward. When imaginary line C (shown in Figs. 5, 7A, 7B, 8A, and 8B) extending from the front to the back of the container 20 is assumed, the front upper end fin 21c is composed of an inclined plate inclined with respect to this imaginary line C. In addition, a plurality of front lower end fins 21d are arranged at intervals from each other in the left-right direction near the lower end of the front frame portion 21b, and like the front upper end fin 21c, are composed of an inclined plate inclined with respect to the imaginary line C so that they are located to the right as they move forward. A plurality of front central fins 21e are arranged at intervals from each other in the left-right direction in the vertical middle part of the front frame portion 21b, and like the front upper end fin 21c, are composed of an inclined plate inclined with respect to the imaginary line C so that they are located to the right as they move forward. In other words, the front upper end fin 21c, the front lower end fin 21d, and the front central fin 21e are inclined in the same direction relative to the imaginary line C.

The multiple front upper intermediate fins 21f are spaced apart from each other in the left-right direction between the front upper end fin 21c and the front central fin 21e, and are made of inclined plates inclined with respect to the imaginary line C so that they are positioned further to the left as they move forward. The multiple front lower intermediate fins 21g are spaced apart from each other in the left-right direction between the front central fin 21e and the front lower end fin 21d, and like the front upper intermediate fin 21f, are made of inclined plates inclined with respect to the imaginary line C so that they are positioned further to the left as they move forward. In other words, the front upper intermediate fin 21f and the front lower intermediate fin 21g are inclined in the same direction with respect to the imaginary line C.

The vertical dimensions of the front upper end fin 21c and the front lower end fin 21d are approximately the same, and are set shorter than the vertical dimensions of the front central fin 21e, the vertical dimensions of the front upper intermediate fin 21f, and the vertical dimensions of the front lower intermediate fin 21g. The vertical dimensions of the front central fin 21e, the vertical dimensions of the front upper intermediate fin 21f, and the vertical dimensions of the front lower intermediate fin 21g are approximately the same.

The rear member 22 has a substantially rectangular rear frame portion 22b. The open inner portion of the rear frame portion 22b is an opening 22a for dispersing the drug. For example, when air flows into the container 20 from the front opening 21a, the air containing the drug flows out from the opening 22a. On the inner side of 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.

The multiple rear upper end fins 21c are arranged at intervals from each other in the left-right direction near the upper end of the rear frame part 22b, and are composed of inclined plates inclined with respect to the imaginary line C so that they are positioned to the right as they move forward. The multiple rear lower end fins 22d are arranged at intervals from each other in the left-right direction near the lower end of the rear frame part 22b, and like the rear upper end fin 22c, are composed of inclined plates inclined with respect to the imaginary line C so that they are positioned to the right as they move forward. The multiple rear center fins 22e are arranged at intervals from each other in the left-right direction in the vertical middle part of the rear frame part 22b, and like the rear upper end fin 22c, are composed of inclined plates inclined with respect to the imaginary line C so that they are positioned to the right as they move forward. In other words, the rear upper end fin 22c, the rear lower end fin 22d, and the rear center fin 22e are inclined in the same direction with respect to the imaginary line C.

The multiple rear upper intermediate fins 22f are arranged at intervals from one another in the left-right direction between the rear upper end fin 22c and the rear central fin 22e, and are configured as inclined plates inclined with respect to the imaginary line C so as to be positioned further left as they move forward. The multiple rear lower intermediate fins 22g are arranged at intervals from one another in the left-right direction between the rear central fin 22e and the rear lower end fin 22d, and like the rear upper intermediate fin 22f, are configured as inclined plates inclined with respect to the imaginary line C so as to be positioned further left as they move forward. In other words, the rear upper intermediate fin 22f and the rear lower intermediate fin 22g are inclined in the same direction with respect to the imaginary line C.

The vertical dimensions of the rear upper end fin 22c and the rear lower end fin 22d are approximately the same, and are set shorter than the vertical dimensions of the rear central fin 22e, the vertical dimensions of the rear upper intermediate fin 22f, and the vertical dimensions of the rear lower intermediate fin 22g. The vertical dimensions of the rear central fin 22e, the vertical dimensions of the rear upper intermediate fin 22f, and the vertical dimensions of the rear lower intermediate fin 22g are approximately the same.

The front fins 21c-21g and the rear fins 22c-22g are arranged so that they are 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, have the same vertical dimensions, and overlap each other when viewed along the imaginary line C. The front lower end fin 21d and the rear lower end fin 22d are arranged at the same height, have the same vertical dimensions, and overlap each other when viewed along the imaginary line C. The front center fin 21e and the rear center fin 22e are arranged at the same height, have the same vertical dimensions, and overlap each other when viewed along the imaginary line C. The front upper intermediate fin 21f and the rear upper intermediate fin 22f are arranged at the same height, have the same vertical dimensions, and overlap each other when viewed along the imaginary line C. Furthermore, the front lower intermediate fin 21g and the rear lower intermediate fin 22g are positioned at the same height, have the same vertical dimensions, and overlap when viewed along the imaginary line C.

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

The inclination angle of the fins 21c-21g, 22c-22g with respect to the imaginary line C can be set, for example, in the range of 10° to 80°. The larger the inclination angle, the higher the air guiding effect of the fins 21c-21g, 22c-22g, which is preferable. On the other hand, if the inclination angle exceeds 80°, the openings 21a, 22a are almost completely blocked by the fins 21c-21g, 22c-22g, causing a sudden increase in air resistance and a decrease in the amount of drug dispersed, so it is preferable to set the inclination angle of the fins 21c-21g, 22c-22g with respect to the imaginary line C to 80° or less. Furthermore, if the inclination angle of the fins 21c-21g and 22c-22g with respect to the imaginary line C is less than 10°, the effect of guiding weak wind in the left-right direction will suddenly decrease, so it is preferable to set the inclination angle of the fins 21c-21g and 22c-22g with respect to the imaginary line C to 10° or more. Although not shown, fins that guide wind in the up-down direction may also be provided.

(Effect of fins)
As described above, the container 20 rotates around a vertical line when exposed to wind at a certain wind speed or higher, thereby efficiently diffusing the medicine to the surroundings. On the other hand, when the wind speed is below a certain speed, the container 20 hardly rotates, so the medicine diffusion effect due to the rotation cannot be expected. However, even in this case, the container 20 of this embodiment is equipped with fins 21c to 21g and 22c to 22g, so that the medicine can be diffused to the surroundings. This point will be explained below.

The dashed lines in Figures 7A and 7B show the flow of wind blowing from the front of the container 20, which is weak enough not to rotate the container 20. The wind blowing from the front passes through the drug-impregnated body 11 while being guided by the front upper middle fin 21f and the front lower middle fin 21g, as partially shown in Figure 7A. The wind that passes through the drug-impregnated body 11 volatilizes the drug. The wind containing the drug is then guided to the right by the rear upper middle fin 22f and the rear lower middle fin 22g.

As shown in part in FIG. 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 central fin 21e. The wind that passes through the drug-impregnated body volatilizes the drug. The wind containing the drug is then guided to the left by the rear upper end fin 22c, the rear lower end fin 22d, and the rear central fin 22e.

As described above, the air containing the medicine is guided by the rear fins 22c to 22g and dispersed to the left and right before being released from the rear side of the container 20. In this way, the air containing the medicine can be dispersed to the left and right before being released, so that the medicine can be easily diffused even when the container 20 does not rotate.

The same is true when wind blows from the back of the container 20, in the opposite manner to the above. In this case, the wind blowing from the back of the container 20 is guided by the rear fins 22c to 22g and passes through the drug-impregnated body 11, and then dispersed to the left and right by the front fins 21c to 21g and released from the front of the container 20. In this way, with the configuration of this embodiment, the drug can be diffused to the surroundings whether the wind is blowing from the front or the back.

However, wind does not necessarily blow from the front or back, but can also blow from the left or right. When wind blows from the left or right of the container 20, the wind flows approximately parallel to the drug-impregnated body 11, and as such, the wind does not pass through the drug-impregnated body 11, and therefore, volatilization of the drug cannot be expected. However, according to this embodiment, the drug can be diffused well even when the wind blows from the left or right. This point will be explained below.

The dashed line in Figure 8A shows the flow of wind blowing from the left of the container 20, and the wind is weak enough not to rotate the container 20. As shown in part in Figure 8A, the wind blowing from the left side is received by the rear upper end fin 22c, rear lower end fin 22d, and rear central fin 22e on the back side of the container 20, and is guided toward the drug-impregnated body 11 inside the container 20. The wind guided in this way volatilizes the drug as it passes through the drug-impregnated body 11. The wind containing the drug then flows out from the front side of the container 20 while being guided by the front upper end fin 21c, front lower end fin 21d, and front central fin 21e.

The dashed line in Figure 8B shows the flow of wind blowing from the right of the container 20, and the wind is weak enough not to rotate the container 20. As shown in part in Figure 8B, the wind blowing from the right side is received by the front upper end fin 21c, the front lower end fin 21d, and the front central fin 21e on the front side of the container 20, and is guided toward the drug-impregnated body 11 inside the container 20. The wind guided in this way volatilizes the drug as it passes through the drug-impregnated body 11. The wind containing the drug then 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 wind blows from the left or right side of container 20, fins 21c to 21g and 22c to 22g receive the wind and guide it toward drug-impregnated body 11 in container 20. Because of this configuration, even if wind blows substantially parallel to drug-impregnated body 11, the wind can be directed at drug-impregnated body 11 to volatilize the drug.

In this way, even if the container 20 does not rotate, the medicine can be diffused to the surroundings no matter what direction the wind blows from.
The above description is based on the assumption that the container 20 of this embodiment is configured to rotate with the wind, and is therefore 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 medicine is diffused by the rotation of the container 20. However, if the container 20 is fixed so as not to rotate, the diffusion effect of the fins 21c to 21g and 22c to 22g can be obtained even in strong winds. In other words, the effect of the fins 21c to 21g and 22c to 22g is not limited to the case where the container 20 is configured to rotate, but is effective even when the container 20 is fixed so as not to rotate.

That is, the container 20 is provided with the front upper middle fin 21f and the front lower middle fin 21g, and the rear upper middle fin 22f and the rear lower middle fin 22g (first guide portion) that guide the wind introduced from the front opening 21a to the right (first direction), and the front upper end fin 21c, the front lower end fin 21d, and the front central fin 21e, and the rear upper end fin 22c, the rear lower end fin 22d, and the rear central fin 22e (second guide portion) that guide the wind to the left (second direction opposite to the first direction). The first guide portion includes the front upper middle fin 21f and the front lower middle fin 21g formed on the front side of the container 20b, and the rear upper middle fin 22f and the rear lower middle fin 22g formed on the back side of the container 20b. 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, and a rear upper end fin 22c, a rear lower end fin 22d, and a rear central fin 22e formed on the rear side of the container 20b. The number of fins 21c to 21g and 22c to 22g is not limited to the number shown in the figure.

As shown in Figures 1 to 3, the front and back sides of the upper part of the container 20 are provided with a front recess 21h (shown in Figure 2) and a back recess 22f (shown in Figure 3), to which the hanging member 40 is attached, each recessed toward the inside of the container 20. The front recess 21h and the back recess 22f are positioned in the left-right center of the container 20. The rotation center line D of the container 20 is located in the left-right center and the front-rear center of the container 20, and this rotation center line D extends in the up-down direction of the container 20. When the container 20 is suspended by the hanging member 40, the rotation center line D is oriented vertically. The connection structure of the hanging member 40 to the container 20 is not limited to the structure shown in the figures.

(Configuration of hanging member 40)
As shown in Figures 2 and 3, the hanging member 40 is configured to suspend the container 20 as an article so as to be rotatable around a vertical line (rotation center line D), and includes a hanging hook 40A, a swivel 40B, and a clip 40C. The swivel 40B and the clip 40C may be provided as necessary. It is also possible to rotate the container 20 by omitting the swivel 40B and using a thread instead of the swivel 40B. Also, the lower part of the swivel 40B may be directly connected to the container 20 without providing the clip 40C.

The container 20 can be hung from a rod-shaped member 100 extending in a substantially horizontal direction, as shown in, for example, Figures 14A and 14B. In this case, the hanging hook 40A can be called a hanging hook 40A for hanging an object from the rod-shaped member 100. Also, as shown in Figure 15, an object can be hung from a rod-shaped member 101 having a large diameter, as will be described in detail later. Examples of the rod-shaped members 100 and 101 include a clothesline pole, various poles, arms, and the like. The rod-shaped members 100 and 101 do not have to be installed strictly horizontally, and may be slightly inclined. Furthermore, the container 20 can be hung from a string 102, as shown in Figure 16. In this case, the hanging hook 40A can be called a hanging hook 40A for hanging an object from the string 102. The string 102 may be a string, rope, cord, or long member used for drying clothes or for other purposes, and is hung horizontally. The hanging structure is formed by the hanging hook 40A and the swivel 40B. The swivel 40B is a connecting member for connecting the base member 52 (described later) to the container 20.

As shown in FIG. 1, the swivel 40B, which is one component of the hanging structure, is a freely rotating metal ring and is a conventionally known component. The swivel 40B is also called a return hook, and in this example, when the upper part of the swivel 40B is secured, the lower part can easily rotate around a vertical line. That is, the upper part of the swivel 40B is connected to the lower part of the hanging hook 40A, while the lower part of the swivel 40B is connected to a clip 40C that is attached to the container 20. The clip 40C is fixed to the container 20 by fitting into the front recess 21h and the back recess 22f of the container 20.

The hanging hook 40A has a fastening portion 41. The fastening portion 41 is configured in approximately the upper half of the hanging member 40, and is provided with a fastening portion 41 that circumferentially surrounds the rod-shaped members 100, 101 and is formed so that a portion of the fastening portion 41 in the circumferential direction is discontinuous and openable. As shown in FIG. 11 etc., the fastening portion 41 has an overall shape close to the letter C when the container 20 is not hanging.

In the description of this embodiment, the front, back, left, and right of the hanging hook 40A are defined as shown in Figures 9 to 11, but this is for convenience of description and does not limit the direction in use. When in use, the hanging hook 40A may be positioned so that the back is at the front of the container 20, or the hanging hook 40A may be positioned so that the right or left is at the front of the container 20.

As shown in FIG. 11, when the hanging hook 40A is viewed from the front or back, the fastening portion 41 is configured to be openable in the horizontal direction. Specifically, when the hanging hook 40A is viewed from the front, a discontinuous portion is located on the left side of the fastening portion 41. Therefore, the left side of the fastening portion 41 is openable, and the upper left side (one circumferential side) 42 and the lower left side (the other circumferential side) 43 of the fastening portion 41 are arranged at a distance from each other in the vertical direction. It is to be noted that a discontinuous portion may be located on the right side of the fastening portion 41.

The fastening portion 41 is made of a resin material that is both flexible and pliable. An example of such a resin material is polypropylene, but other resin materials can also be used. The fastening portion 41 is preferably elastic. Since the fastening portion 41 is elastic, even if the open portion of the fastening portion 41 is opened widely, for example as shown in FIG. 14A, the shape can be restored to that shown in FIG. 11 by removing the force thereafter.

Since the fastening portion 41 has the above-mentioned properties (flexibility and flexibility), it can be deformed so that the gap between the upper left portion 42 and the lower left portion 43 of the fastening portion 41 increases, as shown in Figs. 14A and 15. This allows the rod-shaped members 100, 101 to be placed inside the fastening portion 41. It is also possible to deform the fastening portion 41 so that the gap between the upper left portion 42 and the lower left portion 43 decreases, so that the upper left portion 42 and the lower left portion 43 overlap each other in the radial direction, as shown in Fig. 14B. At this time, the upper left portion 42 overlaps the outer surface of the lower left portion 43.

As shown in FIG. 11, the inner surface of the upper left side 42 of the fastening portion 41 has multiple teeth 42a arranged in the circumferential direction, protruding radially inward from the inner surface. These teeth 42a form the engagement portion. All of the teeth 42a have the same shape and are elongated in the front-to-back direction to ensure a wide tooth surface. The spacing between the teeth 42a can be set as desired; for example, the teeth 42a may be adjacent to each other, or a gap may be formed between the teeth 42a.

On the outer surface of the left lower part 43 of the fastening part 41, a plurality of grooves 43a extending in the front-back direction are formed so as to be aligned in the circumferential direction. The grooves 43a form an engaged part that engages 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. This allows the plurality of teeth 42a to be engaged with the plurality of grooves 43a at once, as shown in FIG. 14B. By engaging the plurality of teeth 42a with the plurality of grooves 43a at once, the bonding strength between the left lower part 42 and the left lower part 43 is increased, which is preferable. Note that one tooth 42a may be engaged with one groove 43a. Also, although not shown, teeth may be formed on the left lower part 43 and grooves may be formed on the left upper part 42. Also, convex parts or protrusions may be formed instead of teeth, and concave parts or the like may be formed instead of grooves.

By deforming the fastening portion 41 so that the gap between the upper left side 42 and the lower left side 43 is narrowed, and the diameter of the fastening portion 41 is reduced, the overlapping range between the lower left side 42 and the lower left side 43 is widened, so that many teeth 42a can be engaged with many grooves 43a. In this embodiment, the gap between adjacent teeth 42a, 42a and the gap between adjacent grooves 43a, 43a are set narrow, for example, to 0.5 mm or more and 2.0 mm or less, so that the diameter of the fastening portion 41 can be finely adjusted. In addition, the adjustment range of the diameter of the fastening portion 41 can be set by the circumferential formation range of the teeth 42a and the circumferential formation range of the grooves 43a. The adjustment range of the diameter of the fastening portion 41 can be, for example, 5 mm or more and 30 mm or less.

(Function of the tightening part)
With the above configuration, when hanging the container 20 on the rod-shaped member 100, as shown in Fig. 14B, the diameter of the fastening portion 41 is adjusted to match the outer diameter of the rod-shaped member 100, thereby fastening the rod-shaped member 100. As a result, since the hanging hook 40A is fixed to the rod-shaped member 100, even if a strong wind blows and the container 20 is blown by the wind, the medicine diffuser 1 can be prevented from moving in the longitudinal direction of the rod-shaped member 100.

On the other hand, as shown in FIG. 15, if the container 20 is hung from a large-diameter rod-shaped member 101, the upper left side 42 and the lower left side 43 cannot be overlapped in the radial direction, and the fastening 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 fastened by the fastening portion 41.

In this case, the fastening portion 41 is in a more open state than when no force is applied (Fig. 11), and the elastic force of the fastening portion 41 generates a force that tries to close the fastening portion 41. This elastic force allows the upper and lower portions to hold the rod-shaped member 101 in the vertical direction, and the rod-shaped member 101 can be fastened. As a result, even when the container 20 is hung on a rod-shaped member 101 with a large diameter, the hanging hook 40A can be fixed to the rod-shaped member 101, so that the drug diffuser 1 can be prevented from moving in the longitudinal direction of the rod-shaped member 101 even when the wind is strong.

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

The shapes and positions of the upper finger contact portion 42b and the lower finger contact portion 43b are set so that, when viewed from the top-bottom direction, at least a portion of the upper finger contact portion 42b overlaps at least a portion of the lower finger contact portion 43b. 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 unevenness, texture, fine grooves, etc. to prevent slipping.

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 move the thumb and index finger closer to each other, the left lower portion 42 and the left lower portion 43 move closer to 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. This allows the teeth 42a and the grooves 43a to engage. When the force is increased, as shown in FIG. 14B, the diameter of the tightening portion 41 becomes smaller, allowing the rod-shaped member 100 to be tightened by the tightening portion 41, and in this state the teeth 42a and the grooves 43a engage to maintain the tightening state by the tightening portion 41.

A protruding portion 42c curved radially outward is formed at the lower portion of the left upper portion 42 of the fastening portion 41. The protruding tip of the protruding portion 42c is located radially outward from the left lower portion 43. For example, as shown in FIG. 14A, when inserting the rod-shaped member 100 into the inside of the fastening portion 41, the rod-shaped member 100 can be brought into contact with the lower surface of the protruding portion 42c to be guided to the inside of the fastening portion 41. When the fastening portion 41 in the open state shown in FIG. 11 is brought into the closed state shown in FIG. 14B, the upper end of the left lower portion 43 can be brought into contact with the lower surface of the protruding portion 42c to guide the left lower portion 43 to the inside of the left upper portion 42. Furthermore, when opening the fastening portion 41, the protruding portion 42c is lifted upward from the closed state of the fastening portion 41, and the engagement between the teeth 42a and the grooves 43a is released, and the fastening portion 41 can be easily opened. This allows the drug diffuser 1 to be removed from the rod-shaped member 100.

The upper part of the fastening part 41 is provided with a bent part 44 that is bent so as to protrude upward in the left-right center. The left-right dimension of the bent part 44 becomes shorter as it approaches the upper end of the bent part 44, and it has a shape that points upward when viewed from the front and back. By forming the bent part 44, a recess 44a that is recessed upward is formed on the inner surface of the upper side of the fastening part 41. The width (circumferential dimension) of the recess 44a becomes narrower as it goes up the recess 44a. As shown in FIG. 16, when hanging from a string 102, the string 102 enters and gets caught in the recess 44a. This stabilizes the hanging member 40.

By forming the bent portion 44, the bent portion 44 elastically deforms so as to open when the tightening portion 41 is opened, thereby ensuring a large amount of elastic deformation of the tightening portion 41. In addition, since the bent portion 44 functions like a spring, the springiness of the tightening portion 41 can be increased.

Further, a lower protrusion 45 protruding downward is provided at the lower part of the fastening part 41. An indicator 50, which will be described later, is provided at the lower part of this lower protrusion 45. Furthermore, an upper rib 46 and a side rib 47 protruding radially outward are provided on the outer surface of the fastening part 41. The upper rib 46 extends from the outer surface of the bent part 44 to the upper finger contact part 42b. The side rib 47 extends from the outer surface of the bent part 44 to the lower protrusion 45. The formation of the upper rib 46 and the side rib 47 increases the strength of the fastening part 41, and can prevent it from falling when it is hung from a rod-shaped member 101 with a large diameter as shown in FIG. 15. The upper rib 46 and the side rib 47 may be provided as necessary, and may be omitted.

(Configuration of indicator 50)
The indicator 50 is a dial-type display device provided to indicate the timing when the effect 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 the conventional drug diffuser, the indicator was provided on the container, which resulted in various restrictions on the shape of the container. In particular, in the case of the dial-type indicator 50, it may be desired to set a larger dial 51 to improve visibility, and if such a dial 51 is provided on the container 20, the opening area of the container 20 may be narrowed, and the efficiency of volatilization of the drug may be reduced. 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. In addition, the shape of the container 20 is not limited by the indicator, so that the container 20 can be curved in an S-shape in plan view, as in this embodiment.

The indicator 50 is provided on the lower part of the lower protrusion 45 that protrudes downward from the fastening part 41, and is therefore positioned below the fastening part 41. In other words, since the indicator 50 is positioned below the fastening part 41 and is not on the fastening part 41, the indicator 50 does not impede the flexibility of the fastening part 41. This allows the fastening part 41 to be easily deformed and hung when the hanging hook 40A is hung from the rod-shaped members 100, 101.

The indicator 50 is a dial-type display device that includes a dial 51 with multiple numbers displayed thereon, a base member 52 that rotatably supports the dial 51, and a cover portion 53 formed to cover at least a portion of the surface of the dial 51, and is configured to be able to display desired information by rotating the dial 51. As described above, the indicator 50 of this embodiment is intended to display, as an example of desired information, the timing at which the drug held in the drug holder 11 will lose its effectiveness, and can also be called an end-of-period display device. The indicator 50 can also display, as an example of desired information, the start time of use of the drug diffuser 1, and in this case can also be called a start-of-period display device. By displaying the start time of use of the drug diffuser 1, the end time can be known.

As shown in Figures 12A and 12B, the dial 51 is, for example, in the form of a circular plate and is made of a resin material or the like. The dial 51 may also be in the form of a polygonal plate. A through hole 51a is formed in the center of the dial 51, penetrating in the front-to-back direction. The through hole 51a is circular because it is a hole that allows the dial 51 to rotate. The center line of the through hole 51a is the center line of rotation of the dial 51.

On the surface 51b of the dial 51, a number of numbers are displayed in a circumferential direction. The numbers displayed here indicate the months and are 1 to 12, but this is just an example, and the Gregorian calendar year, letters, or symbols may also be displayed. The same numbers as those displayed on the surface 51b are also displayed on the back surface 51c of the dial 51. The numbers on the surface 51b of the dial 51 and the numbers on the back surface 51b match in the circumferential direction, so for example, the "1" on the back surface 51b of the dial 51 is located directly behind the "1" on the surface 51b of the dial 51. The surface 51b and back surface 51c of the dial 51 are each a display surface that displays the timing at which the medicine loses its effectiveness. Note that numbers may be displayed on only one of the surface 51b and back surface 51c of the dial 51.

The dial 51 is formed with a cylindrical peripheral wall portion 51d that protrudes from the periphery 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. In addition, a protrusion 51e is provided on the back side of the dial 51 radially outward from the peripheral wall portion 51d. The protrusion 51e protrudes radially outward. A portion of the peripheral wall portion 51db in the circumferential direction is interrupted, and the protrusion 51e is arranged to correspond to this interrupted portion.

The base member 52 is disposed on the back side of the dial 51 and is a part that rotatably supports the dial 51. The base member 52 is a generally circular plate extending in the vertical and horizontal directions along the back side of the dial 51, and therefore can also be called a support plate. The lower part of the lower protrusion 45 of the tightening part 41 is integrally molded on the upper part of the base member 52. The lower part of the base member 52 is provided with a connecting plate part 54 that protrudes downward. The upper part of the swivel 40B for connecting to the container 20 can be attached to the lower part of this connecting plate part 54.

As shown in FIG. 10, the back side of the base member 52 is provided with two back side markers 52a, 52a for matching the numbers on the dial 51. The back side markers 52a can be configured, for example, as arrows, symbols, lines, letters, etc., and in this embodiment, are configured as lines of a predetermined length extending in the radial direction. One back side marker 52a indicates the start of the period, and the other back side marker 52a indicates the end of the period. For example, when use is started in January, the "1" on the back side 51c of the dial 51 is aligned with one back side marker 52a. Then, the other back side marker 52a indicates "9". In other words, when the period of use is expected to be nine months, the relative positions of the two back side markers 52a, 52a are set so that the other back side marker 52a indicates the month nine months after the month aligned with one back side marker 52a. The relative positions of the backside markers 52a, 52a can be set as desired. Also, if the expected usage period is one year, for example, one backside marker 52a is sufficient.

The cover portion 53 is a portion that is placed on the front side of the dial 51, and is configured to cover the radially inner area of the surface 51b of the dial 51 and to leave the radially outer area (the area where the numbers are displayed) exposed. The cover portion 53 is in the shape of a circular plate, similar to the base member 52. The surface of the cover portion 53 is provided with two front side marker portions 53a, 53a that are aligned with the numbers on the dial 51. The front side marker portions 53a are intended to indicate the start and end of the period, similar to the back side marker portion 52a.

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

12A and 12B show the shapes of the fastening portion 41, the lower protrusion 45, the base member 52, the cover portion 53, the connecting plate portion 54, and the thin hinge 55 immediately after molding. As shown in these figures, the fastening portion 41, the lower protrusion 45, the base member 52, the cover portion 53, the connecting plate portion 54, and the thin hinge 55 are integrally molded from 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 portion 53 are in an unfolded state. In the unfolded state, the hanging hook 40A, the base member 52, and the cover portion 53 pass through approximately the same plane and are arranged to virtually form the plane. That is, when the hanging hook 40A, the base member 52, and the cover part 53 are integrally molded, if the hanging hook 40A, the base member 52, and the cover part 53 are significantly misaligned from the same plane, the difference between the deep and shallow parts of the mold will become large, which may complicate the mold structure and may lead to molding defects.
By arranging the base member 52 and the cover portion 53 so that they form approximately the same plane, the mold structure required for integral molding is simplified and moldability is improved, thereby enabling costs to be further reduced.

On the front surface of the base member 52, three base side columnar parts 52b are formed at intervals from each other in the circumferential direction. The base side columnar parts 52b are inserted into the through holes 51a of the dial 51 and rotatably support the dial 15. The base side columnar parts 52b extend in the front-to-back direction, and the three base side columnar parts 52b form one support shaft that supports the dial 51. In other words, the three base side columnar parts 52b are arranged at intervals from each other in the circumferential direction of the support shaft. The number of base side columnar parts 52b is not limited to three, and may be two or less, or four or more.

The outer surfaces of the three base-side columnar parts 52b are formed as arc surfaces located on the same circumference, and are formed to slide against 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 against the outer surfaces of the three base-side columnar parts 52b, allowing the dial 51 to rotate smoothly.

On the other hand, the cover side columnar portion 53b is formed on the back surface of the cover portion 53, which is inserted between the base side columnar portions 52b and connected to the base side columnar portions 52b. The cover side columnar portion 53b is formed in a triangular tube shape, and by fitting inside the three base side columnar portions 52b, it is connected to the inner surface of the three base side columnar portions 52b. For example, the outer surface of the cover side columnar portion 53b and the inner surface of the three base side columnar portions 52b can be provided with engagement claws or the like to engage the two. The shape of the cover side columnar portion 53b is not limited to a triangular tube shape, and may be any shape that can fit into the base side columnar portion 52b to provide a rotation prevention effect, such as a polygonal shape such as a square or pentagon.

The cover side columnar portion 53b is triangular tubular, and three base side columnar portions 52b are arranged on its outer surface to connect the two, preventing the base member 52 and the cover portion 53 from rotating relative to each other around the rotation center line of the dial 51. In other words, the cover side columnar portion 53b and the base side columnar portion 52b form a rotation prevention structure that prevents the base member 52 and the cover portion 53 from rotating relative to each other, and the indicator 50 is equipped with this rotation prevention structure. As a result, even if the thin hinge 55 breaks, for example, the base member 52 and the cover portion 53 will not rotate relative to each other, and the start and end times of the front and back are correctly maintained.

A specific example of the anti-rotation structure will be described. In this embodiment, the three apexes 53c of the cover-side columnar portion 53b are disposed between the base-side columnar portions 52b that are 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 apexes 53c come into contact with the base-side columnar portions 52b, thereby preventing the relative rotation. The apexes 53c are stopper portions.

A ring-shaped wall 52e is formed on the periphery of the base member 52. The ring-shaped wall 52e protrudes toward the front side and extends in a ring shape around the rotation center line of the dial 51. The radial center of the ring-shaped wall 52e coincides with the rotation center line of the dial 51. A large number of engagement protrusions 52f are arranged in a circumferential direction on the inner peripheral surface of the ring-shaped wall 52e. When the cover side columnar portion 53b is inserted between the three base side columnar portions 52b to align the cover portion 53 with the base member 52, the tip of the convex portion 51e is arranged to contact the engagement protrusion 52f in the ring-shaped wall 52e. When the convex portion 51e and the engagement protrusion 52f come into contact with each other and are engaged, the dial 51 becomes difficult to rotate and accidental rotation is prevented. On the other hand, if an attempt is made to intentionally rotate the dial 51 with a finger, the convex portion 51e is elastically deformed, and the engagement state with the engagement protrusion 52f is released, allowing the dial 51 to rotate.

(When using the drug diffuser 1)
The drug diffuser 1 configured as above can be used outdoors by hanging it from rod-shaped members 100, 101 as shown in Fig. 14B or Fig. 15, or by hanging it from a string 102 as shown in Fig. 16. When natural wind hits the container 20 while it is hanging, if the wind is strong, the container 20 will rotate because the hanging member 40 is equipped with a swivel 40B. The stronger the wind is, the faster the rotating speed of the container 20 will increase. This allows the drug to be diffused efficiently.

On the other hand, in light breezes, the container 20 may not rotate, but as mentioned above, the drug diffuser 1 of this embodiment can effectively diffuse the drug even when the container 20 does not rotate.

(Effectiveness test in light winds)
Here, the efficacy test in a light breeze will be described. The test in a light breeze was carried out in a windless, thermostatic room of 8 tatami mats with 5 ventilations per hour. At a distance of 0.1 m from the wall of this test room, insect nets containing test insects were hung 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. In other words, 3 x 3 = a total of 9 insect nets were installed vertically and horizontally. The test insects were female Culex pipiens mosquitoes. The drug impregnated in the drug-impregnated body 11 was an insecticide made of a pyrethroid compound. The drug diffuser 1 was hung at a height of 1 m, 1.1 m away from the front of the insect net at the left end (1.2 m away from the wall), and the container 20 was blasted with air 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. The insect net was installed, followed by the installation of the pesticide diffuser 1, and the number of knocked-down insects was observed over time after the installation of the pesticide diffuser 1. The test was repeated three times, and the KT50 value was calculated from the knock-down rate at each observation time by the Bliss Probit method.

As a result, the KT50 value (min) for the test insects placed away from the pesticide dispenser 1 was 9.12-10.32, demonstrating sufficient pesticide efficacy. Furthermore, the KT50 value (min) for the test insects placed close to the pesticide dispenser 1 was 4.54-6.37, proving that the pesticide was even more effective.

Next, as a comparative example, a container (described in JP 2011-19507 A) without fins 21c-21g, 22c-22g was prepared and a similar test was carried out. As a result, for the test insects placed away from the pesticide diffuser in the comparative example, the KT50 value (min) was 11.33-12.93, indicating that it took longer to knock them down than in the example. Also, for the test insects placed close to the pesticide diffuser in the comparative example, the KT50 value (min) was 4.71-6.92, indicating that it took the same or longer to knock them down than in the example.

As described above, it was confirmed that in a light breeze (when the container is not rotating), the pesticide diffuser 1 of this embodiment is equally or more effective than the pesticide diffuser of the comparative example. In particular, it was confirmed that the pesticide diffuser 1 of this embodiment is significantly more effective than the comparative example at positions away from the pesticide diffuser. This shows that the pesticide diffuser 1 of this embodiment is able to diffuse the pesticide over a wider area in a light breeze.

The reason why it is highly effective in light breezes is that, as shown in Figures 7A and 7B, the fins 21c-21g and 22c-22g guide the medicine to both sides and spread it over a wide area. In addition, the medicine can be spread even when the wind blows from the left as shown in Figure 8A, and when the wind blows from the right as shown in Figure 8B, so high effectiveness can be obtained regardless of the orientation of the medicine diffuser 1.

(Effects of the embodiment)
As described above, according to this embodiment, a part of the circumferential direction of the fastening portion 41 of the hanging hook 40A is discontinuous, and therefore, as shown in FIG. 14A, by deforming the fastening portion 41 so that the discontinuous part is opened, it becomes possible to insert the rod-shaped member 100 into the inside of the fastening portion 41 from the opened part of the fastening portion 41. Then, as shown in FIG. 14B, when the teeth 42a are engaged with the grooves 43a, the fastening portion 41 is closed and the rod-shaped member 100 is fastened. At this time, since a plurality of teeth 42a are arranged in the circumferential direction, by changing the teeth 42a engaged with the grooves 43a, the circumferential length of the fastening portion 41 can be reliably fastened in accordance with the circumferential length of the rod-shaped member 100. Therefore, since the hanging hook 40A, which is an integrally molded product of a resin material, can be fixed to the rod-shaped member 100, it is possible to reduce costs.

When the drug diffuser body 10 is hung by the hanging hook 40A, the drug is diffused to the outside as air flows in and out of the openings 21a, 22a of the container 20. In addition, 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.

The base member 52 and cover portion 53 of the indicator 50 are integrally molded via the thin hinge 55, reducing the number of parts. During assembly, the dial 51 is placed on the base member 52, and the thin hinge 55 is folded to position the cover portion 53 on the front side of the dial 51, thereby obtaining an indicator 50 that rotatably supports the dial 51, making assembly easier.

The above-described embodiment is merely illustrative in all respects and should not be interpreted as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. The drug diffuser 1 can also be used without rotating. For example, the container 20 can be hung from a doorknob (not shown) by the hanging member 40.

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

As explained above, the present invention can be applied to, for example, a pesticide diffuser that diffuses pesticides into the air.
