In order to detachably fix the cover member 20 and the container 10, a pair of circumferentially extending ridges 41 are formed on the inner surface near the upper end of the side wall portion 4 so as to extend in the circumferential direction. These ridges 41 are detachably fitted into mounting grooves 119 formed in the second portion 112 of the container body 1 .

A plurality of elongated volatilization holes 42 extending in the vertical direction are formed in the side wall portion 4 , and the internal space of the side wall portion 4 communicates with the outside through these volatilization holes 42 . As will be described later, the chemical solution is volatilized to the outside from these volatilization holes 42 .

The plurality of volatilization holes 42 have substantially the same length in the vertical direction, and are formed at predetermined intervals along the circumferential direction of the side wall portion 4 . The upper ends of the volatilization holes 42 lined up in this manner are spaced apart by the same length as the upper ends of the side wall portions 4 . Therefore, the plurality of volatilization holes 42 arranged in the circumferential direction are also arranged so that their positions in the vertical direction change according to the upper end of the side wall portion 4 .

A vertically extending second groove 43 is formed between the upper end of each volatilization hole 42 and the upper end of the side wall portion 4 .

The depth of the concave portion 31 is substantially constant over the entirety, and can be, for example, about 0.01 to 3.0 mm. Further, a protrusion 32 is provided near the center of the recess 31 and protrudes upward.

<1-3. volatilization body>
Next, the volatilization body will be described with reference to FIGS. 11 to 13. FIG. 11 is a perspective view of the volatilization body viewed from above, FIG. 12 is a perspective view of the volatilization body viewed from below, and FIG. 13 is a side view of the volatilization body attached to a container.

As shown in FIGS. 11 and 12, the volatilization body 30 is attached to the lid member 2, and extends upward from a rectangular plate-like substrate 51 and the opposite sides of the substrate 51. A pair of volatilization plates 52 and a pair of liquid absorption plates 53 extending downward from the substrate 51 are provided. Both the volatilization plate 52 and the liquid absorption plate 53 are formed in a rectangular shape. The outer diameter of the substrate is approximately the same as the outer diameter of the lid member. A rectangular through-hole 511 is formed in the center of the substrate 51 , and the discharge pipe 22 of the lid member 2 is inserted into this through-hole 511 . The sides of the through hole 511 facing each other are connected to the liquid absorption plates 53 described above. These liquid absorption plates 53 are formed in a rectangular shape and extend downward from the through holes 511 .

As shown in FIG. 13, when the volatilization body 30 is attached to the lid member 2, the discharge pipe 22 is inserted into the through hole 511, and the lower wall portion 212 of the lid member 2 is in contact with the upper surface of the substrate 51. It's becoming At this time, the liquid absorption plates 53 are arranged so as to sandwich the discharge pipe 22 and extend slightly below the discharge pipe 22 . That is, when the volatilization body 30 is attached to the lid member 2 , the lower end of the liquid absorption plate 53 is positioned slightly below the lower end of the discharge pipe 22 . Specifically, the lower end of the liquid absorption plate 53 is located below the lower end of the discharge pipe 22 by about 0 to 5 mm.

Further, when the volatilization body 30 is attached to the lid member 2, the volatilization plate 52 is arranged to cover the discharge part 13 of the container body 1 from the side, and the upper end of the volatilization plate 52 is positioned at the third It is located near the part 113 . Therefore, the volatilization plate 52 is arranged at a position substantially facing the volatilization hole 42 of the cover member 20 .

The volatilization body 30 is not particularly limited as long as it is a material capable of sucking up the chemical solution and volatilizing the chemical solution to the outside. For example, various materials such as paper and cloth can be used, preferably non-woven fabric, which can be formed by mixing pulp, polyester, rayon or the like with a binder.

<1-4. Chemical solution>
The liquid medicine contained in the container 10 has an aromatic component as a functional component. However, in addition to these, various components such as a deodorizing component, an insect repellent component, and an antibacterial component can be contained. Such functional ingredients may be either oil-based or water-soluble. In addition, such a functional component can be blended with a component having a water vapor pressure of 0.01 to 20 hPa and easily volatilized. The mixing ratio of such components in the chemical liquid is preferably 0.25 to 2.5% by mass, more preferably 0.5 to 0.75% by mass. Specifically, limonene, linalool, linalyl acetate, α-pinene, and the like can be used as such components, and these function as fragrances. In addition, a component having a low water vapor pressure can also be contained, and examples of such components include vanillin and galacolid. These also function as perfumes.

Also, such a chemical solution can be produced by preparing, for example, surfactants, fragrances, preservatives, UV absorbers, and water. Then, the easily volatilizable functional component described above can be contained together with a predetermined fragrance or as a fragrance.

<2. Assembly and usage of chemical volatilization device>
Next, assembly of the chemical volatilization device will be described with reference to FIGS. 14 to 18. FIG. 14 is a cross-sectional view of the chemical volatilization device, FIG. 15 is an enlarged view of FIG. 14, and FIGS. 16 and 17 are cross-sectional views for explaining discharge of the chemical. 16 and 17, the valve member 23 and the protrusion 32 are omitted for convenience of explanation. First, a liquid medicine is contained in the container main body 1, and the lower end portion of the discharge portion 13 is closed with the cover member 2. As shown in FIG. Next, the volatilization body 30 is attached to the lid member 2 as described above. Subsequently, the cover member 20 is attached to the container 10 . At this time, the cover member 20 is attached so as to cover the container 10 to which the volatilization body 30 is attached from below. As shown in FIG. 14 , when the cover member 20 is completely attached, the ridges 41 of the cover member 20 fit into the attachment grooves 119 of the container body 1 . Also, the lower end of the liquid absorbing plate 53 of the volatilization body 30 is in contact with the bottom surface of the recess 31 .

However, as shown in FIG. 15 , since the lower end of the volatilization body 30 is positioned below the lower end of the discharge pipe 22 , the lower end of the discharge pipe 22 does not touch the bottom surface of the recess 31 . Therefore, a gap is formed between the lower end of the discharge pipe 22 and the bottom surface of the recess 31 . This gap is smaller than the depth of the recess 31 . That is, the lower end of the discharge pipe 22 is arranged inside the recess 31 , for example, at a position about half the depth of the recess 31 . Also, the projection 32 provided in the recess 31 presses the valve body 232 from the lower end of the discharge pipe 22, moving the valve body 232 upward. As a result, the through hole of the valve seat 231 is opened, and the chemical liquid in the container 10 is discharged from the discharge pipe 22 and accumulated in the recess 31 .

Next, volatilization of the chemical will be described. As shown in FIG. 16, the chemical liquid is discharged from the discharge pipe 22 and accumulated in the recess 31, but since the liquid absorption plate 53 of the volatilization body 30 is in contact with the bottom surface of the recess 31, the chemical liquid accumulated in the recess 31 is absorbed by the liquid absorbing plate 53 . The absorbed chemical liquid moves to the volatilization plate 52 via the liquid absorption plate 53 and the substrate 51, is volatilized from the volatilization plate 52, and is volatilized to the outside of the chemical volatilization device through the volatilization holes . As a result, the aromatic effect of the functional ingredient can be obtained.

By the way, when the chemical solution is stored in the concave portion 31 and the lower end of the discharge pipe 22 is immersed in this chemical solution, the inside of the discharge pipe 22 is filled with the chemical solution and air cannot enter. stops. However, when the chemical liquid accumulated in the concave portion 31 is absorbed by the volatilization body 30 and the water level of the chemical liquid in the concave portion 31 is lowered, and the water level of the chemical liquid is lower than the lower end of the discharge pipe 22, that is, as shown in FIG. When the water level of the chemical solution is positioned at the gap between the lower end of the discharge pipe 22 and the bottom surface of the recess 31, air enters from the lower end of the discharge pipe 22, and the chemical solution in the container 10 is pushed out by the air, and the chemical solution is discharged from the discharge pipe 22. is discharged. Thereafter, the discharged chemical solution is accumulated in the recess 31, and when the water level of the chemical solution rises above the lower end of the discharge pipe 22 again, the discharge of the chemical solution stops because air cannot enter the discharge pipe. In this way, the chemical is volatilized to the outside of the chemical volatilization device by the volatilizer 30 while the discharge and stop of the chemical are repeated.

When the liquid medicine in the container 10 runs out or becomes low, the liquid medicine can be replenished. Specifically, after removing the cover member 20 from the container 10 , the lid member 2 is removed from the container body 1 , and the liquid medicine is refilled into the container body 1 through the opening of the discharge portion 13 .

<3. Features>
According to the chemical volatilization device configured as described above, the following effects can be obtained.
(1) Since the fourth groove 45 is formed at the lower end of the side wall portion 4 of the cover member 20, for example, when the container 10 is replaced, the chemical liquid leaks from the volatilization hole 42 and flows downward along the side wall portion 4. Also, the chemical solution can be held in the fourth groove 45 . Therefore, it is possible to suppress the leakage of the chemical liquid from being conspicuous. Furthermore, since the chemical liquid can be held in the fourth groove 45, it is possible to prevent the surroundings of the chemical liquid volatilization device from being soiled by the chemical liquid.

(2) Since the third groove 44 extending downward from the lower end of each volatilization hole 42 is formed on the outer peripheral surface of the cover member 20, for example, even if the chemical leaks from the volatilization hole 42 during replacement of the container 10, Since the liquid medicine is accumulated in the third groove 44 located below, it is possible to suppress the leakage of the liquid medicine from being conspicuous. Furthermore, since the chemical liquid can be held in the third groove 44, it is possible to prevent the surroundings of the chemical liquid volatilization device from being soiled by the chemical liquid.

(3) The lower end of the discharge pipe 22 is in the recess 31, and the chemical solution is discharged from the container 10 only when the water level of the chemical solution in the recess 31 is lower than the lower end of the discharge pipe 22. 22 can be prevented from becoming higher than the lower end. Therefore, it is possible to limit the discharge amount of the chemical solution and prevent a large amount of the chemical solution from being discharged. In addition, since the cover member forms an internal space with the bottom wall portion and the side wall portion, the chemical solution is prevented from leaking from this internal space, but the chemical solution is further accumulated in the recess 31 within this internal space. Therefore, for example, when the chemical volatilization device is moved, it is possible to further prevent the chemical from flowing out of the cover member 20 to the outside. Therefore, it is possible to prevent the surroundings of the chemical volatilization device from becoming dirty with the chemical.

(4) A valve member 23 is provided on the discharge pipe 22 of the container 10 , and the valve member 23 is in a closed state until the cover member 20 is attached to the container 10 and pressed by the projecting portion 32 . Therefore, it is possible to prevent the liquid medicine from leaking from the container 10 at the time of assembly. The chemical solution can volatilize at the same time as the attachment to the

(5) For example, in a chemical volatilization device of a type in which a chemical is stored in a container having an opening formed at the top, a liquid absorbing wick is inserted into the opening of the container, and the chemical is sucked up by the liquid absorbing wick and vaporized. In some cases, the high-pressure component was sucked up first and volatilized. Therefore, in order to secure the use for a certain period of time, it was necessary to add a large amount of components that are difficult to volatilize with a low vapor pressure to the chemical solution. As a result, it was difficult to freely design the fragrance tone. On the other hand, in the chemical liquid volatilization device according to the present embodiment, after the chemical liquid is discharged from the bottom of the container 10, the volatilization body 30 absorbs and volatilizes the chemical liquid, so the component with a high vapor pressure is volatilized first. is prevented. Therefore, since there is no need to add many components with low vapor pressure to the liquid medicine, the degree of freedom in designing the fragrance tone can be improved.

(6) Since the first to third projecting portions 116a to 116c projecting downward are formed on the inner surface of the ceiling wall portion 15 of the container main body 1, the chemical liquid adhering to the ceiling wall portion 15 is removed from the projecting portions 116a to 116c. It can be made easier to gather at the tip. As a result, it is possible to prevent the liquid medicine collected at the tips of the protrusions 116 a to 116 c from dropping and remaining adhered to the ceiling wall 15 . Therefore, it is possible to prevent the problem that the liquid medicine remains in the container 10 but cannot be discharged.

In particular, in the present embodiment, the protruding portions 116a to 116c are concentrically adjacent to each other, so that the chemical solution adhering between the protruding portions 116a to 116c can be easily guided to any of the protruding portions 116a to 116c. In addition, since the second and third projecting portions 116b and 116c are formed in a continuous circular shape, the chemical liquid adhering to any position on the top wall portion 15 is guided to either portion of the projecting portions 116b and 116c. It's easy to do. Therefore, it is possible to further prevent the chemical solution from remaining attached to the top wall portion 15 .

<4. Variation>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the invention. For example, the following changes are possible. Also, the gist of the following modified examples can be combined as appropriate.

<4-1>
In the above embodiment, the configuration of the fourth groove 45 provided in the side wall portion 4 of the cover member 20 is not particularly limited, and various configurations are possible. For example, the fourth groove 45 may not be formed over the entire circumferential direction, and may be formed partially in the circumferential direction. In this case, it is preferable to form the fourth groove 45 at least below the location where the volatilization hole 42 is formed. Moreover, the vertical position of the fourth groove 45 is not particularly limited, and may be between the lower end of the side wall portion 4 and the volatilization hole 42 . Also, a plurality of fourth grooves 45 may be formed at predetermined intervals in the circumferential direction. In this case, the vertical height of all the fourth grooves 45 may be the same, or may be shifted. Furthermore, the fourth groove 45 does not have to extend completely horizontally, and may be slightly inclined.

In the above-described embodiment, the bottom wall portion 3 protrudes radially outward from the side wall portion 4 , but the bottom wall portion 3 may have a shape that does not protrude from the side wall portion 4 . However, when the fourth groove 45 is provided near the boundary between the bottom wall portion 3 and the side wall portion 4, it is preferable that the bottom wall portion 3 protrudes. In addition, regardless of the position of the fourth groove 45, if the bottom wall portion 3 protrudes, the chemical volatilization device can be stably held. From this point of view, it is preferable that the bottom wall portion 3 protrudes.

The first to third grooves 42 to 44 other than the fourth groove 45 are not essential, and even if only the fourth groove 45 is used, the leaked chemical solution can be retained, so that the surroundings of the device can be prevented from being soiled. can. However, if the third groove is provided, it is preferable because it can further hold the chemical solution.

The position, shape, and number of volatilization holes 42 are also not particularly limited, and can be changed as appropriate.

In the above embodiment, the chemical liquid is discharged from the container 10 to the recess 31 through the discharge pipe 22, and the chemical liquid accumulated in the recess 31 is sucked up by the volatilization body. The configuration is not limited to this, and various configurations are possible. For example, a liquid-absorbing wick may be provided at the bottom of the container 10, and the liquid medicine in the container 10 may be discharged to the outside through this liquid-absorbing wick. By contacting the volatilization body 30 with this liquid absorption core, the chemical liquid can be absorbed by the volatilization body 30 through the liquid absorption core. Therefore, the configuration of the lid member 2 is not limited to the above, and if a valve member is attached, the discharge pipe 22 is not necessarily required. It is sufficient if a liquid core is provided. Moreover, the recess 31 is also unnecessary. The liquid-absorbing wick should be designed to absorb the liquid medicine in the container 10 when the valve member is opened. Moreover, the material of the absorbent core can be the same as that of the volatilization body 30, for example. In this way, it is sufficient that the chemical solution can be discharged from the container 10 and the volatilization body 30 can be impregnated with the chemical solution.
