Embodiments for Carrying Out the Invention

[0015] Hereinafter, a chemical liquid volatilization device according to an embodiment of the present invention will be described with reference to the drawings.

[0016] <1. Overall configuration of the chemical volatilization device> Figure 1 is a perspective view of a chemical volatilization apparatus according to this embodiment. As shown in Figure 1, this chemical volatilization apparatus comprises a container 10 for containing the chemical liquid, a cover member 20 that covers the lower end of the container 10, and a volatilizer (not shown in Figure 1) 30 that is housed between the container 10 and the cover member 20 and volatilizes the chemical liquid discharged from the container 10. These components will be described in detail below.

[0017] <1-1. Container> Figure 2 is a side view of the container. As shown in Figure 2, the container 10 comprises a container body 1 with an opening at its lower end in which the liquid medicine is contained, and a lid member 2 that closes the opening at the lower end of the container body 1. These members will be described in detail below.

[0018] <1-1-1. Container Body> Figure 3 is a perspective view of the container body, Figure 4 is a perspective view of the container body from above, and Figure 5 is a cross-sectional view of the container body. As shown in Figures 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 that has a smaller diameter than the main body portion 11 and extends downward from the lower end of the connecting portion 12, and these 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.

[0019] The side wall portion 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.

[0020] The first section 111 extends downward from the periphery of the top wall section 115 and constitutes most of the side wall section 110. Furthermore, the first section 111 has first grooves 114 extending vertically along its entire length, formed at predetermined intervals in the circumferential direction. The lower edge of the first section 111 is circular in shape, but a pair of opposing sections on either side of the axis protrude downward in an arc shape. These sections will be referred to as the lower protrusions 117. Between the two lower protrusions 117, a pair of sections protrude slightly upward in an arc shape. These sections will be referred to as the upper protrusions 118. Thus, the lower edge of the first section 111 is formed by a curve smoothly connecting the pair of lower protrusions 117 and the pair of upper protrusions 118.

[0021] 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 in the second portion 112 at predetermined intervals. These mounting grooves 119 are formed at positions corresponding to the lower projection 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 this lower edge of the third portion 113.

[0022] The connecting portion 12 is formed by an inclined surface that extends radially inward as it goes downward, and a cylindrical discharge portion 13 is connected to the lower end of this connecting portion 12. An opening 131 that opens downward is formed at the lower end of the discharge portion 13. In addition, a male screw 132 is formed near the lower end of the outer circumferential surface of the discharge portion 13.

[0023] As shown in Figures 4 and 5, the top wall portion 115 is formed in a circular shape in plan view, and a first projection portion 116a projecting downward is formed in the center of the inner surface of the top wall portion 115. The first projection portion 116a is formed in a circular arc shape in cross-section. Then, with the first projection portion 116a as the center, a circular second projection portion 116b and a third projection portion 116c are formed concentrically on the inner surface of the top wall portion 115, and these second projection portion 116b and third projection portion 116c project downward in a circular arc shape in cross-section. Furthermore, recesses 116e to 116g are formed on the upper surface of the top wall portion 115 corresponding to these projection portions 116a to 116c.

[0024] 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 liquid medicine is contained in this internal space.

[0025] <1-1-2. Lid component> Next, the lid member 2 will be described with reference to Figures 6 and 7. Figure 6 is a perspective view of the lid member, and Figure 7 is a cross-sectional view of the lid member. As shown in Figures 6 and 7, the lid member 2 comprises a cylindrical lid body 21 and a small-diameter discharge pipe 22 connected to the lower end of the lid body 21, and these are integrally formed. 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 thread 213 is formed on the inner surface of the side wall portion 211, and this female thread 213 is screwed into the male thread 132 of the discharge portion 13 of the container body 1. In this way, the lid member 2 is fixed to the container body 1. 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.

[0026] The valve member 23 attached to the lower end of the discharge pipe 22 comprises a valve seat 231 fixed to the discharge pipe 22 and having a through hole formed therein, a valve body 232 that can open and close the through hole of the valve seat 231, and a spring 133 that presses the valve body 232 against the valve seat 231. Normally, the valve body 232 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, opening the through hole.

[0027] <1-2. Cover components> 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 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.

[0028] As shown in Figures 8 to 10, the cover member 20 comprises a disc-shaped bottom wall portion 3 and a cylindrical side wall portion 4 that rises upward from slightly inward from 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 follows the lower end of the first portion 111. In addition, in order to detachably fix the cover member 20 to 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. These protrusions 41 are detachably fitted into mounting grooves 119 formed in the second portion 112 of the container body 1.

[0029] Multiple 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 and the outside are in communication through these volatilization holes 42. As will be described later, the chemical solution is volatilized to the outside through these volatilization holes 42.

[0030] The multiple volatilization holes 42 are approximately the same in 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 each of the volatilization holes 42 arranged in this manner are positioned at the same distance 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 vertical position changes in accordance with the upper end of the side wall portion 4.

[0031] A second groove 43 extending vertically 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 / lower groove) 44 extending vertically is formed between the lower end of each volatilization hole 42 and the lower end of the side wall portion 4. When the cover member 20 is attached to the container 10, the first groove 114 of the container, the second groove 43, volatilization holes 42, and the third groove 44 of the cover member 20 are arranged to be aligned vertically. In this way, the alignment of the multiple grooves 114, 43, 44 and the volatilization holes 42 in the vertical direction provides a sense of design unity.

[0032] The bottom wall portion 3 has an outer diameter larger than the outer diameter of the side wall portion 4. That is, the bottom wall portion 3 protrudes radially outward from the lower end of the side wall portion 4. This bottom wall portion 3 is installed on a predetermined mounting surface and supports the entire chemical volatilization device.

[0033] Furthermore, a fourth groove (circumferential groove) 45 extending over the entire circumferential direction is formed near the boundary between the bottom wall portion 3 and the side wall portion 4, that is, at the lower end of the side wall portion 4, and the lower ends of each third groove 44 are connected to this fourth groove 45.

[0034] A square-shaped recess 31 is formed on the upper surface of the bottom wall 3, enclosed by the side walls 4, and functions as a space for storing the chemical solution, as will be described later. The depth of the recess 31 is almost constant throughout, and can be, for example, about 0.01 to 3.0 mm. Furthermore, a projection 32 is provided near the center of the recess 31, protruding upward.

[0035] <1-3. Volatile substances> Next, the volatile material will be explained with reference to Figures 11 to 13. Figure 11 is a perspective view of the volatile material from above, Figure 12 is a perspective view of the volatile material from below, and Figure 13 is a side view of the volatile material when attached to a container.

[0036] As shown in Figures 11 and 12, the volatilizer 30 is attached to the lid member 2 and comprises a rectangular plate-shaped substrate 51, a pair of volatilizing plates 52 extending upward from opposing sides of the substrate 51, and a pair of liquid-absorbing plates 53 extending downward from the substrate 51. Both the volatilizing plates 52 and the liquid-absorbing plates 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, into which the discharge pipe 22 of the lid member 2 is inserted. The liquid-absorbing plates 53 described above 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.

[0037] As shown in Figure 13, when the volatile material 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-absorbing plate 53 is positioned so as to sandwich the discharge pipe 22 and extends slightly below the discharge pipe 22. That is, when the volatile material 30 is attached to the lid member 2, the lower end of the liquid-absorbing plate 53 is positioned slightly below the lower end of the discharge pipe 22. Specifically, the lower end of the liquid-absorbing plate 53 is positioned approximately 0 to 5 mm below the lower end of the discharge pipe 22.

[0038] Furthermore, when the volatile element 30 is attached to the lid member 2, the volatile plate 52 is positioned to cover the discharge section 13 of the container body 1 from the side, and the upper end of the volatile plate 52 is located near the third section 113 of the container body 1. Therefore, the volatile plate 52 is positioned approximately opposite the volatile hole 42 of the cover member 20.

[0039] The volatilizer 30 is not particularly limited as long as it is a material that can absorb the chemical solution and volatilize it to the outside. For example, various materials such as paper and cloth can be used, and preferably a nonwoven fabric is preferred, which can be formed by mixing a binder with pulp, polyester, rayon, etc.

[0040] <1-4. Medicinal Solution> The liquid medicine contained in container 10 contains aromatic components as functional ingredients. However, it can also contain various other components such as deodorizing components, insect repellent components, and antibacterial components. Such functional ingredients may be oily or water-soluble. Furthermore, volatile components with a water vapor pressure of 0.01 to 20 hPa can be incorporated into such functional ingredients. The proportion of such components in the liquid medicine is preferably 0.25 to 2.5% by mass, and more preferably 0.5 to 0.75% by mass. Specifically, such components can include, for example, limonene, linalool, linalyl acetate, and α-pinene, which function as fragrances. Components with low water vapor pressure can also be included, for example, vanillin and galacoride. These also function as fragrances.

[0041] Furthermore, such a chemical solution can be produced, for example, by preparing a surfactant, fragrance, preservative, UV absorber, and water. The aforementioned volatile functional components can then be included together with a predetermined fragrance, or as a fragrance itself.

[0042] <2. Assembly and Use of the Chemical Volatilization Device> Next, the assembly of the chemical volatilization device will be explained with reference to Figures 14 to 18. Figure 14 is a cross-sectional view of the chemical volatilization device, Figure 15 is an enlarged view of Figure 14, and Figures 16 and 17 are cross-sectional views illustrating the discharge of the chemical volatilization device. For the sake of clarity, the valve member 23 and the projection 32 are omitted in Figures 16 and 17. First, the chemical volatilization device is placed in the container body 1, and the lower end of the discharge section 13 is closed with the lid member 2. Next, the volatilizer 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 with the volatilizer 30 attached from below. As shown in Figure 14, when the cover member 20 is attached, the projection 41 of the cover member 20 fits into the mounting groove 119 of the container body 1. Also, the lower end of the liquid absorption plate 53 of the volatilizer 30 contacts the bottom surface of the recess 31.

[0043] However, as shown in Figure 15, the lower end of the volatile material 30 is located below the lower end of the discharge pipe 22, so the lower end of the discharge pipe 22 does not come into contact with 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. In other words, the lower end of the discharge pipe 22 is positioned inside the recess 31, for example, at about half the depth of the recess 31. In addition, 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 opens, and the liquid chemical in the container 10 is discharged from the discharge pipe 22 and accumulates in the recess 31.

[0044] Next, the volatilization of the chemical solution will be explained. As shown in Figure 16, the chemical solution is discharged from the discharge pipe 22 and accumulates in the recess 31. Since the liquid-absorbing plate 53 of the volatilizer 30 is in contact with the bottom surface of the recess 31, the chemical solution accumulated in the recess 31 is absorbed by the liquid-absorbing plate 53. The absorbed chemical solution 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 to the outside of the chemical solution volatilization device through the volatilization holes 42. This allows for the acquisition of an aromatic effect from the functional components.

[0045] Incidentally, when the chemical solution is stored in the recess 31 and the lower end of the discharge pipe 22 is submerged in this chemical solution, the inside of the discharge pipe 22 is filled with the chemical solution and air cannot enter, so the discharge of the chemical solution stops. However, when the chemical solution stored in the recess 31 is absorbed by the volatile material 30 and the level of the chemical solution in the recess 31 decreases, and the level of the chemical solution falls below the lower end of the discharge pipe 22, that is, as shown in Figure 17, when the level of the chemical solution is located in 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 this air pushes out the chemical solution in the container 10, causing the chemical solution to be discharged from the discharge pipe 22. After that, when the discharged chemical solution accumulates in the recess 31 and the level of the chemical solution rises above the lower end of the discharge pipe 22 again, air cannot enter the discharge pipe, so the discharge of the chemical solution stops. In this way, the discharge and stopping of the chemical solution are repeated, and the chemical solution is volatilized to the outside of the chemical solution volatilization device by the volatilizer 30.

[0046] If the liquid medicine in container 10 runs out or becomes low, the liquid medicine can be replenished. That is, after removing the cover member 20 from container 10, the lid member 2 is removed from the container body 1, and the liquid medicine is replenished into the container body 1 through the opening of the discharge section 13.

[0047] <3. Features> The following effects can be obtained with the chemical volatilization apparatus configured as described above. (1) Since a fourth groove 45 is formed at the lower end of the side wall portion 4 of the cover member 20, even if, for example, liquid chemical leaks from the volatilization hole 42 when the container 10 is replaced and flows down along the side wall portion 4, the liquid chemical can be retained in the fourth groove 45. Therefore, the visibility of the leaked liquid chemical can be suppressed. Furthermore, since the liquid chemical can be retained in the fourth groove 45, it is possible to prevent the area around the liquid chemical volatilization device from being soiled by the liquid chemical.

[0048] (2) On the outer surface of the cover member 20, a third groove 44 is formed that extends downward from the lower end of each volatilization hole 42. For example, even if the chemical solution leaks from the volatilization hole 42 when the container 10 is replaced, the chemical solution will accumulate in the third groove 44 below it, thus preventing the leaked chemical solution from being noticeable. Furthermore, because the chemical solution can be held in the third groove 44, it is possible to prevent the area around the chemical solution volatilization device from being soiled by the chemical solution.

[0049] (3) The lower end of the discharge pipe 22 is located within the recess 31, and the chemical solution is only discharged from the container 10 when the level of the chemical solution in the recess 31 falls below the lower end of the discharge pipe 22. This prevents the level of the chemical solution from rising above the lower end of the discharge pipe 22. Therefore, the amount of chemical solution discharged can be limited, and the discharge of large quantities of chemical solution can be prevented. In addition, since the cover member forms an internal space with its bottom wall and side wall, leakage of the chemical solution from this internal space is prevented. Furthermore, the chemical solution is further accumulated in the recess 31 within this internal space, so for example, when the chemical solution vaporization device is operated, it is possible to further prevent the chemical solution from flowing out of the cover member 20. Therefore, it is possible to prevent the area around the chemical solution vaporization device from being contaminated by the chemical solution.

[0050] (4) A valve member 23 is provided in 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 projection 32. Therefore, leakage of the liquid chemical from the container 10 during assembly can be prevented, while when the cover member 20 is attached to the container 10, the valve member 23 is pressed by the projection 32 and opens, so that the liquid chemical can be vaporized at the same time as the cover member 20 is attached to the container 10.

[0051] (5) For example, in a chemical volatilization device of the type in which a chemical liquid is contained in a container with an opening formed at the top, and a liquid-absorbing wick is inserted into the opening of the container to draw up the chemical liquid and volatilize it, components with high vapor pressure were sometimes drawn up and volatilized first. Therefore, in order to ensure use for a certain period of time, it was necessary to add a larger amount of components with low vapor pressure that do not volatilize easily to the chemical liquid. As a result, it was difficult to freely design the fragrance. In contrast, in the chemical volatilization device according to this embodiment, the chemical liquid is discharged from the bottom of the container 10, and then the volatilizer 30 absorbs and volatilizes the chemical liquid, so that components with high vapor pressure do not volatilize first. Therefore, it is not necessary to add a large amount of components with low vapor pressure to the chemical liquid, and the degree of freedom in designing the fragrance can be improved.

[0052] (6) Since the first to third protrusions 116a to 116c that protrude downward are formed on the inner surface of the top wall portion 15 of the container body 1, the liquid medicine adhering to the top wall portion 15 can be easily collected 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 will fall off and will not remain adhering to the top wall portion 15. Therefore, the problem of liquid medicine remaining in the container 10 but being unable to be discharged can be suppressed.

[0053] In particular, in this embodiment, since the protrusions 116a to 116c are adjacent to each other in a concentric manner, any liquid adhering between the protrusions 116a to 116c is easily guided to one of the protrusions 116a to 116c. Furthermore, since the second and third protrusions 116b and 116c are formed in a continuous circular shape, any liquid adhering to any position on the top wall portion 15 is easily guided to one of the protrusions 116b or 116c. Therefore, it is possible to further suppress the liquid remaining adhering to the top wall portion 15.

[0054] <4. Variation> 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 invention. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

[0055] <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 does not have to be formed over the entire circumferential direction, but may be formed only in a part of the circumferential direction. In this case, it is preferable to form the fourth groove 45 at least below the location where the volatilization holes 42 are formed. Furthermore, 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 holes 42. In addition, multiple fourth groove portions 45 may be formed at predetermined intervals in the circumferential direction. In this case, the vertical height of all fourth grooves 45 may be the same, or they may be offset. Furthermore, the fourth groove 45 does not have to extend completely horizontally, and may be slightly inclined.

[0056] In the above embodiment, the bottom wall portion 3 protrudes radially outward from the side wall portion 4, but the bottom wall portion 3 may be shaped so that it does not protrude from the side wall portion 4. However, if the fourth groove 45 is provided near the boundary between the bottom wall portion 3 and the side wall portion 4, it is preferable for the bottom wall portion 3 to protrude. Furthermore, regardless of the position of the fourth groove 45, if the bottom wall portion 3 protrudes, the chemical volatilization device can be held stably, and if the chemical leaks from the fourth groove 45, the chemical can be adhered to the bottom wall portion 3. From this viewpoint, it is preferable for the bottom wall portion 3 to protrude.

[0057] The first to third grooves 42 to 44, other than the fourth groove 45, are not essential. Even with only the fourth groove 45, the leaked chemical solution can be retained, thus preventing contamination of the area around the device. However, the presence of the third groove is preferable because it can retain even more chemical solution.

[0058] The position, shape, and number of the volatilization holes 42 are not particularly limited and can be changed as appropriate. However, it is preferable to form the volatilization holes 42 in an elongated shape, as this limits the amount of liquid leakage if the liquid leaks downward from the volatilization holes 42. On the other hand, since the volatilization holes 42 are formed to be long in the vertical direction, they do not hinder the volatilization of the liquid.

[0059] The other components of the cover member 20 are not particularly limited, and it is sufficient that it covers at least the lower end of the container 10 and has volatilization holes.

[0060] <4-2> The shape of the recess 31 is not particularly limited, and its shape in plan view may not be rectangular. Also, the depth of the recess 31 does not necessarily have to be constant. However, the lower end of the discharge pipe 22 must be inside the recess 31, and a gap must be formed between it 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 inside 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. For example, it is preferable that the lower end of the discharge pipe 22 be positioned at a position 50 to 80% of the depth of the recess 31 from the bottom surface of the recess 31. In addition, the area around the recess 31 on the upper surface of the bottom wall 3 may be flat, but at least a part of it can be inclined. That is, at least a part of the surface around the recess 31 can be made into an inclined surface that slopes toward the recess 31. This allows the chemical solution adhering to the area around the recess 31 to be collected in the recess 31.

[0061] <4-3> The shape of the volatilizer 30 is not particularly limited and may be other than the plate shape described above. However, in order to draw up the chemical solution, a part of the volatilizer 30 needs to be positioned below the lower end of the discharge pipe 22 and 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 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 near the opposite of the volatilization hole 42. Furthermore, 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.

[0062] <4-4> The shape of the container 10 is not particularly limited; it is sufficient that it has an internal space capable of containing the liquid chemical and that a discharge pipe 22, which is 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. Furthermore, a valve member 23 attached to the discharge pipe 22 is not necessarily required, but it is preferable to provide one from the viewpoint of preventing the liquid chemical from leaking during assembly. However, the structure and type of the valve member are not particularly limited as long as it is configured to be closed under normal conditions and open during assembly.

[0063] <4-5> In the above embodiment, the liquid medicine is discharged from the container 10 to the recess 31 via the discharge pipe 22, and the liquid medicine accumulated in the recess 31 is absorbed by the volatile material. However, the configuration for absorbing the medicine from the container 10 into the volatile material 30 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 inside the container 10 may be discharged to the outside via this wick. If this liquid-absorbing wick is in contact with the volatile material 30, the liquid medicine can be absorbed into the volatile material 30 via the wick. Therefore, the configuration of the lid member 2 is not limited to the above, and the discharge pipe 22 is not necessarily required as long as a valve member is attached. For example, a valve member 23 and a liquid-absorbing wick may be provided in an opening formed in the container body 1. Also, the recess 31 becomes unnecessary. The liquid-absorbing wick should be designed to absorb the liquid medicine inside the container 10 when the valve member is open. Furthermore, the material of the liquid-absorbing wick can be the same as that of the volatile material 30, for example. Thus, the device should be configured such that the liquid chemical is discharged from the container 10 and impregnated into the volatile material 30.

[0064] <4-6> The components of the chemical solution in the above embodiment are just an example; other chemical solutions can be used as long as they are absorbed by the volatile material 30 and volatilized.

[0065] <4-7> The chemical volatilization device of the above embodiment is composed of three parts: a container 10, a cover member 20, and a volatilizer 30. However, these three parts can be further composed of multiple parts, as long as they have a configuration that performs these functions externally. In that case, the parts can be formed from different materials.

[0066] The container 10 and cover member 20 are preferably made of resin material, but metal can be used in part, and the material is not particularly limited. [Explanation of Symbols]
