International Publication No. 2017/077946

In the above-mentioned chemical solution volatilization device, a cap that covers the liquid absorbent wick is attached before use, and the cap is removed from the container to expose the liquid absorbent wick, after which the lower container is attached to the container. However, since the liquid absorbent wick is impregnated with the chemical solution even before use, there is a risk of the chemical solution leaking when the cap is removed. In addition, after the cap is removed, the liquid absorbent wick is turned downward and the lower container is attached, which may cause the chemical solution to leak from the liquid absorbent wick at that time.

The present invention has been made to solve the above problems, and aims to provide a chemical solution volatilization device that can prevent the chemical solution from leaking from the container before use.

The chemical solution volatilization device according to the present invention comprises a container in which a chemical solution is stored and in which a discharge section is formed at the lower end from which the chemical solution is discharged, a volatilizer that absorbs and volatilizes the chemical solution discharged from the discharge section of the container, and a cover member that covers at least the lower end of the container, and the discharge section of the container is provided with a valve member that is normally closed and opens when the cover member is attached.

In the above-mentioned chemical solution volatilization device, the valve member is configured to be opened by being pressed, and a protrusion that presses the valve member is formed inside the cover member, so that when the cover member is attached to the container, the protrusion of the cover member presses the valve member to open the valve member.

In the above-mentioned chemical solution volatilization device, the valve member can be configured to include a valve seat having a through hole, a valve body that can open and close the through hole of the valve seat, and a spring that urges the valve body downward against the valve seat, and the protrusion presses the valve body.

In the above-mentioned chemical solution volatilization device, the container is provided with a discharge pipe that constitutes the discharge section, and a recess is formed on the inner surface of the cover member for storing the chemical solution discharged from the discharge pipe, and the discharge pipe is inserted into the recess so that a gap is formed between the lower end of the discharge pipe and the bottom surface of the recess, and a part of the volatilization body can be positioned between the lower end of the discharge pipe and the bottom of the recess.

The chemical solution volatilization device of the present invention can prevent the chemical solution from leaking from the container before use.

The following describes a chemical solution volatilization device according to one embodiment of the present invention, with reference to the drawings.

<1. Overall configuration of chemical solution volatilization device>
Fig. 1 is a perspective view of a chemical solution volatilization device according to the present embodiment. As shown in Fig. 1, the chemical solution volatilization device includes a container 10 in which a chemical solution is contained, a cover member 20 that covers the lower end of the container 10, and a volatilization body (omitted in Fig. 1) 30 that is contained between the container 10 and the cover member 20 and volatilizes the chemical solution discharged from the container 10. These members will be described in detail below.

<1-1. Container>
Fig. 2 is a side view of the container. As shown in Fig. 2, the container 10 includes a container body 1 having an opening at the bottom end thereof and containing a medicinal solution, and a lid member 2 for closing the opening at the bottom end of the container body 1. These members will be described in detail below.

<1-1-1. Container body>
Fig. 3 is a perspective view of the container body, Fig. 4 is a perspective view of the container body seen from above, and Fig. 5 is a cross-sectional view of the container body. As shown in Figs. 3 to 5, the container body 1 comprises a cylindrical main body portion 11, a connecting portion 12 connected to the lower end of the main body portion 11, and a cylindrical discharge portion 13 having a smaller diameter than the main body portion 11 and extending downward from the lower end of the connecting portion 12, which are integrally formed. The main body portion 11 comprises a cylindrical side wall portion 110 and a top wall portion 115 that closes the upper end of the side wall portion.

The side wall 110 is composed of a first portion 111 extending in the vertical direction, a second portion 112 having a slightly smaller diameter than the first portion 111 and connected to the lower end of the first portion 111, and a third portion 113 having a slightly smaller diameter than the second portion 112 and connected to the lower end of the second portion 112. Therefore, a step is formed at the boundary between the first portion 111 and the second portion 112, and a step is also formed at the boundary between the second portion 112 and the third portion 113.

The first portion 111 extends downward from the periphery of the top wall portion 115 and constitutes the majority of the side wall portion 110. In addition, the first portion 111 is formed with first grooves 114 that extend over the entire vertical direction at a predetermined interval in the circumferential direction. The lower edge of the first portion 111 is formed in a circular shape, but a pair of portions that face each other across the axis protrude downward in an arc shape. Hereinafter, these portions will be referred to as lower protrusions 117. In addition, between the two lower protrusions 117, a pair of portions that protrude upward in a slight arc shape are formed. Hereinafter, these portions will be referred to as upper protrusions 118. In this way, the lower edge of the first portion 111 is formed by a curve that smoothly connects the pair of lower protrusions 117 and the pair of upper protrusions 118.

The lower edge of the second portion 112 extends parallel to the lower edge of the first portion 111. Therefore, the vertical width of the second portion 112 is generally constant. In addition, a pair of mounting grooves 119 extending in the circumferential direction are formed at a predetermined interval in the second portion 112. These mounting grooves 119 are each formed at a position corresponding to the lower protrusion 117 described above. The lower edge of the third portion 113 extends horizontally in a side view, and the connecting portion 12 is connected to the lower edge of this third portion 113.

The connecting portion 12 is formed by an inclined surface that extends radially inward as it goes downward, and the cylindrical discharge portion 13 is connected to the lower end of the connecting portion 12. The lower end of the discharge portion 13 is formed with an opening 131 that opens downward. In addition, a male thread 132 is formed near the lower end of the outer circumferential surface of the discharge portion 13.

As shown in Figures 4 and 5, the top wall 115 is formed in a circular shape in a plan view, and a first protrusion 116a that protrudes downward is formed in the center of the inner surface of the top wall 115. The first protrusion 116a is formed in an arc-shaped cross section. Then, circular second protrusion 116b and third protrusion 116c are formed concentrically on the inner surface of the top wall 115 with the first protrusion 116a at the center, and these second protrusion 116b and third protrusion 116c protrude downward in an arc-shaped cross section. Also, recesses 116e to 116g are formed on the upper surface of the top wall 115 to correspond to these protrusions 116a to 116c.

The container body 1 has an internal space surrounded by the main body portion 11, the connecting portion 12, and the discharge portion 13 described above, and the medicinal liquid is contained in this internal space.

<1-1-2. Lid member>
Next, the lid member 2 will be described with reference to Figs. 6 and 7. Fig. 6 is a perspective view of the lid member, and Fig. 7 is a cross-sectional view of the lid member. As shown in Figs. 6 and 7, the lid member 2 includes a cylindrical lid body 21 and a small-diameter discharge pipe 22 connected to the lower end of the lid body 21, which are integrally formed. In addition, a valve member 23 is attached to the lower end of the discharge pipe 22. The lid body 21 has a cylindrical side wall portion 211 and a lower wall portion 212 that closes the lower end of the side wall portion 211. A female screw 213 is formed on the inner surface of the side wall portion 211, and this female screw 213 and the male screw 132 of the discharge portion 13 of the container body 1 are screwed together. As a result, the lid member 2 is fixed to the container body 1. In addition, a through hole is formed in the center of the lower wall portion 212, and the discharge pipe 22 is connected to this through hole.

The valve member 23 attached to the lower end of the discharge pipe 22 includes a valve seat 231 fixed to the discharge pipe 22 and having a through hole formed therein, a valve body 232 that closes the through hole of the valve seat 231 in an openable and closable manner, and a spring 133 that presses the valve body 232 against the valve seat 231. The valve body 232 normally closes the through hole of the valve seat 231 by the spring 233, but when the valve body 232 is pressed from below, the valve body 232 is pushed upward against the spring 233 to open the through hole.

<1-2. Cover member>
Next, the cover member 20 will be described with reference to Figures 8 to 10. Figure 8 is a perspective view of the cover member as seen from above, Figure 9 is a plan view of the cover member, and Figure 10 is a cross-sectional view of the cover member.

As shown in Figures 8 to 10, the cover member 20 has a disk-shaped bottom wall portion 3 and a cylindrical side wall portion 4 that rises upward from a position slightly inside the outer edge of the bottom wall portion 3. When the cover member 20 is attached to the container 10, the upper end of the side wall portion 4 contacts the step at the boundary between the first portion 111 and the second portion 112 of the container body 1, and the inner surface of the side wall portion 4 contacts the second portion 112. Therefore, the upper end of the side wall portion 4 is formed in a shape that fits along the lower end of the first portion 111. In addition, in order to removably fix the cover member 20 and the container 10, a pair of circumferentially extending protrusions 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 protrusions 41 are removably fitted into the mounting grooves 119 formed in the second portion 112 of the container body 1.

The side wall 4 has a plurality of elongated volatilization holes 42 extending in the vertical direction, and these volatilization holes 42 connect the internal space of the side wall 4 to the outside. As described below, the medicinal liquid volatilizes to the outside through these volatilization holes 42.

The multiple volatilization holes 42 have approximately the same length in the vertical direction, and are formed at a predetermined interval along the circumferential direction of the side wall portion 4. The upper ends of the volatilization holes 42 arranged in this manner are positioned so that they are spaced apart at the same length as the upper end of the side wall portion 4. Therefore, the multiple volatilization holes 42 arranged in the circumferential direction are also arranged so that their positions in the vertical direction change to match the upper end of the side wall portion 4.

A second groove 43 extending in the vertical direction is formed between the upper end of each volatilization hole 42 and the upper end of the side wall portion 4. Similarly, a third groove (upper and lower groove) 44 extending in the vertical direction is formed between the lower end of each volatilization hole 42 and the lower end of the side wall portion 4. Then, when the cover member 20 is attached to the container 10, the first groove 114 of the container, the second groove 43 of the cover member 20, the volatilization hole 42, and the third groove 44 are arranged so as to be aligned in the vertical direction. In this way, a sense of unity in design is achieved by lining up the multiple grooves 114, 43, 44 and the volatilization holes 42 in the vertical direction.

The bottom wall portion 3 has an outer diameter larger than the outer diameter of the side wall portion 4. In other words, the bottom wall portion 3 protrudes radially outward from the lower end of the side wall portion 4. This bottom wall portion 3 is placed on a specified installation surface and supports the entire chemical solution volatilization device.

In addition, near the boundary between the bottom wall portion 3 and the side wall portion 4, i.e., at the lower end of the side wall portion 4, a fourth groove (circumferential groove) 45 is formed, which extends in the entire circumferential direction, and the lower ends of each of the third grooves 44 are connected to this fourth groove 45.

A recess 31 that is square in plan view is formed in the portion of the upper surface of the bottom wall 3 that is surrounded by the side wall 4, and functions as a space for storing the medicinal solution as described below. The depth of the recess 31 is almost constant throughout, and can be, for example, about 0.01 to 3.0 mm. Furthermore, a protrusion 32 is provided near the center of this recess 31, protruding upward.

<1-3. Volatilization>
Next, the volatilizer will be described with reference to Figures 11 to 13. Figure 11 is a perspective view of the volatilizer seen from above, Figure 12 is a perspective view of the volatilizer seen from below, and Figure 13 is a side view of the volatilizer when attached to a container.

As shown in Figures 11 and 12, the volatilizer 30 is attached to the lid member 2 and includes a rectangular plate-like base plate 51, a pair of volatilizer plates 52 extending upward from opposing sides of the base plate 51, and a pair of liquid absorbing plates 53 extending downward from the base plate 51. The volatilizer plate 52 and the liquid absorbing plate 53 are both formed in a rectangular shape. The outer diameter of the base plate is approximately the same as the outer diameter of the lid member. A rectangular through hole 511 is formed in the center of the base plate 51, and the discharge pipe 22 of the lid member 2 is inserted into this through hole 511. The aforementioned liquid absorbing plates 53 are connected to the opposing sides of the through hole 511. These liquid absorbing plates 53 are formed in a rectangular shape and extend downward from the through hole 511.

As shown in FIG. 13, when the volatilizer 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. At this time, the liquid suction plate 53 is disposed so as to sandwich the discharge pipe 22, and further extends slightly downward than the discharge pipe 22. In other words, when the volatilizer 30 is attached to the lid member 2, the lower end of the liquid suction plate 53 is positioned slightly below the lower end of the discharge pipe 22. Specifically, the lower end of the liquid suction plate 53 is positioned approximately 0 to 5 mm below the lower end of the discharge pipe 22.

When the volatilizer 30 is attached to the cover member 2, the volatilizer plate 52 is positioned so as to cover the discharge section 13 of the container body 1 from the side, and the upper end of the volatilizer plate 52 is located near the third portion 113 of the container body 1. Therefore, the volatilizer plate 52 is positioned generally opposite the volatilizer hole 42 of the cover member 20.

The volatilizer 30 is not particularly limited as long as it is made of a material that can absorb the liquid medicine and volatilize it to the outside. For example, various materials such as paper and cloth can be used, and nonwoven fabric is preferable, and the nonwoven fabric can be made of pulp, polyester, rayon, etc. mixed with a binder.

<1-4. Chemical solution>
The medicinal liquid contained in the container 10 has an aromatic component as a functional component. However, in addition to this, various components such as a deodorant component, an insect repellent component, and an antibacterial component can be contained. Such functional components may be either oil-based or water-soluble. In addition, such functional components can be blended with components that are easily volatilized and have a water vapor pressure of 0.01 to 20 hPa. The blending rate of such components in the medicinal liquid is preferably 0.25 to 2.5 mass%, and more preferably 0.5 to 0.75 mass%. Specifically, such components can be, for example, limonene, linalool, linalyl acetate, α-pinene, etc., which function as fragrances. In addition, components with low water vapor pressure can also be contained, and such components can be, for example, vanillin, galaclide, etc., which also function as fragrances.

Such a chemical solution can be produced by mixing, for example, a surfactant, a fragrance, a preservative, a UV absorber, and water. The functional components that are prone to vaporization described above can be contained together with a specific fragrance or as a fragrance.

2. Assembly and use of chemical volatilization device
Next, the assembly of the chemical solution volatilization device will be described with reference to Figures 14 to 18. Figure 14 is a cross-sectional view of the chemical solution volatilization device, Figure 15 is an enlarged view of Figure 14, and Figures 16 and 17 are cross-sectional views for explaining the discharge of the chemical solution. For convenience of explanation, the valve member 23 and the protrusion 32 are omitted in Figures 16 and 17. First, the chemical solution is stored in the container body 1, and the lower end of the discharge part 13 is closed by the lid member 2. Next, the volatilization body 30 is attached to the lid member 2 as described above. Next, 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 the bottom. As shown in Figure 14, when the attachment of the cover member 20 is completed, the protrusion 41 of the cover member 20 fits into the attachment groove 119 of the container body 1. In addition, the lower end of the liquid absorbing plate 53 of the volatilization body 30 contacts the bottom surface of the recess 31.

However, as shown in FIG. 15, the lower end of the volatilizer 30 is located below the lower end of the discharge pipe 22, so the lower end of the discharge pipe 22 does not contact 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 located within the recess 31, for example, at a position about half the depth of the recess 31. In addition, the protrusion 32 provided on 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 opens, and the chemical solution in the container 10 is discharged from the discharge pipe 22 and accumulates in the recess 31.

Next, the volatilization of the medicinal liquid will be explained. As shown in FIG. 16, the medicinal liquid is discharged from the discharge pipe 22 and accumulates in the recess 31, but since the liquid absorbing plate 53 of the volatilizer 30 is in contact with the bottom surface of the recess 31, the medicinal liquid accumulated in the recess 31 is absorbed by the liquid absorbing plate 53. The absorbed medicinal liquid moves to the volatilization plate 52 via the liquid absorbing plate 53 and the substrate 51, is volatilized from the volatilization plate 52, and is further volatilized from the volatilization hole 42 to the outside of the medicinal liquid volatilization device. This makes it possible to obtain an aromatic effect due to the functional ingredients.

However, when the liquid medicine is stored in the recess 31 and the lower end of the discharge pipe 22 is immersed in the liquid medicine, the inside of the discharge pipe 22 is filled with the liquid medicine and air cannot enter, so the discharge of the liquid medicine stops. However, when the liquid medicine stored in the recess 31 is absorbed by the volatilizer 30 and the level of the liquid medicine in the recess 31 drops, and the level of the liquid medicine drops below the lower end of the discharge pipe 22, that is, when the level of the liquid medicine is located in the gap between the lower end of the discharge pipe 22 and the bottom surface of the recess 31 as shown in FIG. 17, air enters from the lower end of the discharge pipe 22, and the liquid medicine in the container 10 is pushed out by this air, and the liquid medicine is discharged from the discharge pipe 22. After that, when the discharged liquid medicine is stored in the recess 31 and the level of the liquid medicine rises again above the lower end of the discharge pipe 22, air cannot enter the discharge pipe, so the discharge of the liquid medicine stops. In this way, the discharge and stopping of the chemical solution is repeated, and the chemical solution is evaporated to the outside of the chemical solution evaporation device by the evaporator 30.

When the medicinal liquid in the container 10 runs out or becomes low, it can be replenished with the medicinal liquid. That is, after removing the cover member 20 from the container 10, the lid member 2 is removed from the container body 1, and the medicinal liquid is replenished into the container body 1 through the opening of the discharge part 13.

<3. Features>
According to the chemical solution volatilization device configured as above, the following effects can be obtained.
(1) 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 protrusion 32. This prevents the liquid medicine from leaking from the container 10 during assembly, while at the same time, when the cover member 20 is attached to the container 10, the valve member 23 is pressed by the protrusion 32 to open, allowing the liquid medicine to volatilize at the same time as the cover member 20 is attached to the container 10. This prevents the liquid medicine from leaking from the container 10 before use.

(2) The lower end of the discharge pipe 22 is in the recess 31, and the chemical liquid is discharged from the container 10 only when the level of the chemical liquid in the recess 31 falls below the lower end of the discharge pipe 22. This prevents the chemical liquid level from rising above the lower end of the discharge pipe 22. This limits the amount of chemical liquid discharged, and prevents a large amount of chemical liquid from being discharged. In addition, the cover member forms an internal space with the bottom wall and side wall, preventing the chemical liquid from leaking from this internal space. However, the chemical liquid is further accumulated in the recess 31 within this internal space. This further prevents the chemical liquid from flowing out of the cover member 20 when the chemical liquid volatilization device is moved, for example. This prevents the area around the chemical liquid volatilization device from becoming dirty with the chemical liquid.

(3) A third groove 44 is formed on the outer peripheral surface of the cover member 20, extending downward from the lower end of each volatilization hole 42. For example, even if the medicinal liquid leaks from the volatilization hole 42 when replacing the container 10, the medicinal liquid collects in the third groove 44 located below, preventing the leaked medicinal liquid from becoming noticeable. Furthermore, since the medicinal liquid can be held in the third groove 44, the surroundings of the medicinal liquid volatilization device can be prevented from becoming dirty with the medicinal liquid.

(4) Since the fourth groove 45 is formed at the lower end of the side wall portion 4 of the cover member 20, even if the medicinal liquid leaks from the volatilization hole 42 when replacing the container 10 and flows downward along the side wall portion 4, the medicinal liquid can be retained in the fourth groove 45. Therefore, it is possible to prevent the leaked medicinal liquid from being noticeable. Furthermore, since the medicinal liquid can be retained in the fourth groove 45, it is possible to prevent the surroundings of the medicinal liquid volatilization device from becoming dirty with the medicinal liquid.

(5) For example, in a type of chemical solution volatilization device in which a chemical solution is stored in a container with an opening at the top, and an absorbent wick or the like is inserted into the opening of the container, and the chemical solution is sucked up and volatilized by the absorbent wick, components with high vapor pressure may be sucked up and volatilized first. Therefore, in order to ensure a certain period of use, it was necessary to mix a large amount of components with low vapor pressure that are difficult to volatilize into the chemical solution. As a result, it was difficult to freely design the fragrance tone. In contrast, in the chemical solution volatilization device of this embodiment, after the chemical solution is discharged from the bottom of the container 10, the volatilizer 30 absorbs and volatilizes the chemical solution, preventing components with high vapor pressure from volatilizing first. Therefore, since there is no need to mix a large amount of components with low vapor pressure into the chemical solution, the freedom of designing the fragrance tone can be improved.

(6) The first to third protrusions 116a to 116c that protrude downward are formed on the inner surface of the top wall 15 of the container body 1, which makes it easier for the liquid medicine adhering to the top wall 15 to collect at the tips of the protrusions 116a to 116c. As a result, the liquid medicine that has collected at the tips of the protrusions 116a to 116c falls and is prevented from remaining attached to the top wall 15. This makes it possible to prevent the problem of the liquid medicine remaining in the container 10 being unable to be discharged.

In particular, in this embodiment, since the protrusions 116a to 116c are adjacent to each other in a concentric circle, the medicinal liquid adhering between the protrusions 116a to 116c can be easily guided to one of the protrusions 116a to 116c. Furthermore, since the second and third protrusions 116b, 116c are formed in a continuous circular shape, the medicinal liquid adhering to any position on the top wall portion 15 can be easily guided to one of the protrusions 116b, 116c. This further prevents the medicinal liquid from remaining attached to the top wall portion 15.

4. Modifications
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, the following modifications are possible. In addition, the gist of the following modifications can be combined as appropriate.

<4-1>
The configuration of the valve member 23 is not particularly limited, and the aspects shown in the above embodiment are merely exemplary. That is, it is sufficient that the valve member 23 is normally closed, but is configured to be in an open state when the cover member 20 is attached to the container 10. Therefore, although the valve member 23 in the above embodiment controls the operation of the valve body 232 with the coil spring 233, other springs may be used, and the shape of the valve body 232 may be such that it is pressed by the protrusion 32. Therefore, the shape of the protrusion 32 is not particularly limited. In addition, the valve member 23 may be electrically configured to be normally closed, but is configured to be in an open state when the cover member 20 is attached to the container 10, rather than being a mechanical valve member.

<4-2>
The shape of the recess 31 is not particularly limited, and the shape in plan view may be other than rectangular. The depth of the recess 31 does not necessarily have to be constant. However, the lower end of the discharge pipe 22 needs to be in the recess 31, and a gap needs to be formed between the lower end of the discharge pipe 22 and the bottom surface of the recess 31. The position of the lower end of the discharge pipe 22 is not particularly limited as long as it is in the recess 31, but if the lower end of the discharge pipe 22 is close to the upper end of the recess 31, the chemical solution may overflow. Therefore, for example, it is preferable that the lower end of the discharge pipe 22 is disposed at a position 50 to 80% of the depth of the recess 31 from the bottom surface of the recess 31. In addition, on the upper surface of the bottom wall portion 3, the periphery of the recess 31 may be flat, but at least a part of it can be inclined. That is, at least a part of the surface surrounding the recess 31 can be an inclined surface inclined toward the recess 31. This allows the chemical solution attached to the periphery of the recess 31 to be collected in the recess 31.

<4-3>
The shape of the volatilizer 30 is not particularly limited, and may be other than the plate-like shape described above. However, in order to suck up the chemical solution, a part of the volatilizer 30 needs to be located below the lower end of the discharge pipe 22 and in a position where it is immersed in the chemical solution, but it does not necessarily have to be in contact with the bottom surface of the recess 31. In this respect, the shape of the volatilizer 30 does not have to be the three parts 51 to 53 as described above, but in order to efficiently volatilize the chemical solution to the outside of the device, it is preferable that a part of the volatilizer 30 extends to a position facing the volatilization hole 42. In addition, the material constituting the volatilizer 30 is not particularly limited as long as it can absorb the chemical solution and volatilize it to the outside. In addition, the volatilizer 30 can be composed of multiple materials.

<4-4>
The shape of the container 10 is not particularly limited as long as it has an internal space capable of accommodating at least the drug solution and the discharge pipe 22 to be inserted into the recess 31 is formed at the lower end of the container 10. Therefore, the shape of the container 10, including the shape of the discharge pipe 22, can be changed as appropriate.

The configuration of the cover member 20 is not particularly limited, as long as it covers at least the lower end of the container 10 and has a recess 31 for storing the drug solution. Therefore, the shape of the cover member 20, including the shape and position of the volatilization hole 42 and the presence or absence of the grooves 43 to 45, can be modified in various ways. For example, if a gap can be formed between the cover member 20 and the container 10, the volatilization hole 42 is not necessarily required. Also, the cover member 20 may have a structure in which a part of the volatilization body 30 is exposed to the outside.

<4-6>
In the above embodiment, the drug solution is discharged from the container 10 to the recess 31 through the discharge pipe 22, and the drug solution accumulated in the recess 31 is sucked up by the volatilizer, but the configuration for absorbing the drug from the container 10 into the volatilizer 30 is not limited to this, and various configurations are possible. For example, an absorbent wick may be provided at the bottom of the container 10, and the drug solution in the container 10 may be discharged to the outside through this absorbent wick. If this absorbent wick is brought into contact with the volatilizer 30, the drug solution can be absorbed into the volatilizer 30 through the absorbent wick. Therefore, the configuration of the cover member 2 is not limited to the above, and if a valve member is attached, the discharge pipe 22 is not necessarily required, and for example, the valve member 23 and the absorbent wick may be provided in the opening formed in the container body 1. In addition, the recess 31 is also unnecessary. It is sufficient that the absorbent wick is capable of absorbing the drug solution in the container 10 when the valve member is opened. In addition, the material of the absorbent wick may be the same as that of the volatilizer 30, for example. In this manner, it is sufficient that the container 10 is configured so that the chemical solution can be discharged from the container 10 and the volatilizer 30 can be impregnated with the chemical solution.

<4-7>
The components of the chemical solution in the above embodiment are merely examples, and chemical solutions with other components can also be used as long as they can be absorbed by the volatilizer 30 and volatilized.

<4-8>
The chemical solution volatilization device of the above embodiment is composed of three parts, the container 10, the cover member 20, and the volatilization body 30, but these three parts can be further composed of multiple parts as long as they have a configuration that performs these functions in terms of external appearance. In that case, the parts can be formed from different materials.

The container 10 and cover member 20 are preferably made of a resin material, but metal may also be used in part, and the material is not particularly limited.
