[0013] Hereinafter, a chemical solution volatilization device according to one embodiment of the present invention will be described with reference to the drawings.

[0014] <1. Overall configuration of chemical volatilization device> Fig. 1 is a perspective view of a liquid medicine volatilization device according to this embodiment. As shown in Fig. 1, this liquid medicine volatilization device includes a container 10 in which a liquid medicine is stored, a cover member 20 that covers the lower end of the container 10, and a volatilizer (omitted in Fig. 1) 30 that is stored between the container 10 and the cover member 20 and volatilizes the liquid medicine discharged from the container 10. These members will be described in detail below.

[0015] <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 liquid, and a lid member 2 that closes the opening at the bottom end of the container body 1. These members will be described in detail below.

[0016] <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 includes 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 includes a cylindrical side wall portion 110 and a top wall portion 115 closing the upper end of the side wall portion.

[0017] 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.

[0018] 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 extending over the entire vertical direction at predetermined intervals in the circumferential direction. The lower edge of the first portion 111 is formed in a circular shape, but a pair of portions facing 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 protruding upward in a slight arc shape is 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 in which the pair of lower protrusions 117 and the pair of upper protrusions 118 are smoothly connected.

[0019] The lower edge of the second portion 112 extends parallel to the lower edge of the first portion 111. Therefore, the width of the second portion 112 in the up-down direction is generally constant. Furthermore, the second portion 112 is formed with a pair of mounting grooves 119 extending in the circumferential direction at a predetermined interval. These mounting grooves 119 are formed at positions corresponding to the above-mentioned lower protrusions 117. 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.

[0020] The connecting portion 12 is formed by an inclined surface that extends radially inward as it extends downward, and a cylindrical discharge portion 13 is connected to the lower end of the connecting portion 12. An opening 131 that opens downward is formed at the lower end of the discharge portion 13. In addition, a male thread 132 is formed near the lower end of the outer circumferential surface of the discharge portion 13.

[0021] As shown in Figs. 4 and 5, the top wall 115 is formed in a circular shape in a plan view, and a first protrusion 116a protruding downward is formed at the center of the inner surface of the top wall 115. The first protrusion 116a is formed in an arc-shaped cross section. Then, a circular second protrusion 116b and a third protrusion 116c are formed concentrically around the first protrusion 116a on the inner surface of the top wall 115, 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.

[0022] The container body 1 has an internal space surrounded by the above-mentioned main body portion 11, connecting portion 12, and discharge portion 13, and the medicinal liquid is contained in this internal space.

[0023] <1-1-2. Lid parts> 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.

[0024] 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.

[0025] <1-2. Cover parts> 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 viewed from above, Figure 9 is a plan view of the cover member, and Figure 10 is a cross-sectional view of the cover member.

[0026] As shown in Figs. 8 to 10, the cover member 20 includes 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 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 so as to extend in the circumferential direction. These protrusions 41 are adapted to be detachably fitted into mounting grooves 119 formed in the second portion 112 of the container body 1.

[0027] The side wall 4 is formed with a plurality of elongated volatilization holes 42 extending in the vertical direction, and the internal space of the side wall 4 communicates with the outside through these volatilization holes 42. As described later, the medicinal liquid volatilizes to the outside through these volatilization holes 42.

[0028] The multiple volatilization holes 42 have approximately the same length in the up-down 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 as to be spaced apart by 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 up-down direction change in accordance with the upper end of the side wall portion 4.

[0029] Between the upper end of each volatilization hole 42 and the upper end of the side wall portion 4, a second groove 43 extending in the vertical direction is formed. Similarly, between the lower end of each volatilization hole 42 and the lower end of the side wall portion 4, a third groove (upper and lower groove) 44 extending in the vertical direction is formed. 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 obtained by aligning the multiple grooves 114, 43, 44 and the volatilization hole 42 in the vertical direction.

[0030] 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 placed on a predetermined installation surface and supports the entire chemical solution volatilization device.

[0031] 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 extending around the entire circumferential direction is formed, and the lower ends of each of the third grooves 44 are connected to this fourth groove 45.

[0032] A recess 31 having a square shape in plan view is formed in the portion of the upper surface of the bottom wall 3 surrounded by the side wall 4, and functions as a space for storing a 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 and protrudes upward.

[0033] <1-3.Volatilized bodies> 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.

[0034] As shown in FIG. 11 and FIG. 12, the volatilizer 30 is attached to the cover member 2 and includes a rectangular plate-like substrate 51, a pair of volatilization 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. The volatilization plate 52 and the liquid absorbing plate 53 are both formed in a rectangular shape. The outer diameter of the substrate is approximately the same as the outer diameter of the cover member. A rectangular through hole 511 is formed in the center of the substrate 51, and the discharge pipe 22 of the cover member 2 is inserted into the through hole 511. The aforementioned liquid absorbing plates 53 are connected to 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.

[0035] 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 below 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 located slightly below the lower end of the discharge pipe 22. Specifically, the lower end of the liquid suction plate 53 is located approximately 0 to 5 mm below the lower end of the discharge pipe 22.

[0036] In addition, when the volatilizer 30 is attached to the cover member 2, the volatilizer plate 52 is arranged so as to cover the discharge part 13 of the container body 1 from the side, and the upper end of the volatilizer plate 52 is located near the third part 113 of the container body 1. Therefore, the volatilizer plate 52 is arranged at a position generally opposite to the volatilizer hole 42 of the cover member 20.

[0037] 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, or the like mixed with a binder.

[0038] <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 contain a component that is easily volatilized with a water vapor pressure of 0.01 to 20 hPa. The blending rate of such components is preferably 0.25 to 2.5 mass%, and more preferably 0.5 to 0.75 mass%. Specifically, such components may include, for example, limonene, linalool, linalyl acetate, α-pinene, etc., which function as fragrances. In addition, components with low water vapor pressure may also be contained, and such components may include, for example, vanillin, galaclide, etc., which also function as fragrances.

[0039] Such a chemical solution can be produced by mixing, for example, a surfactant, a fragrance, a preservative, a UV absorber, and water, and the functional component that is easily vaporized as described above can be contained together with a predetermined fragrance or as a fragrance.

[0040] <2. Assembly and use of chemical volatilization device> Next, the assembly of the liquid chemical volatilization device will be described with reference to Figs. 14 to 18. Fig. 14 is a cross-sectional view of the liquid chemical volatilization device, Fig. 15 is an enlarged view of Fig. 14, and Figs. 16 and 17 are cross-sectional views for explaining the discharge of the liquid chemical. For convenience of explanation, the valve member 23 and the protrusion 32 are omitted in Figs. 16 and 17. First, the liquid chemical 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 side. As shown in Fig. 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.

[0041] However, as shown in FIG. 15, since the lower end of the volatilizer 30 is located below the lower end of the discharge pipe 22, 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 in the recess 31, for example, at a position about half the depth of the recess 31. In addition, the protrusion 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 solution in the container 10 is discharged from the discharge pipe 22 and accumulates in the recess 31.

[0042] Next, the volatilization of the liquid medicine will be described. As shown in Fig. 16, the liquid medicine 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 liquid medicine accumulated in the recess 31 is absorbed by the liquid absorbing plate 53. The absorbed liquid medicine 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 liquid medicine volatilization device. This allows the aromatic effect of the functional components to be obtained.

[0043] Incidentally, 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 that 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 that the discharge of the liquid medicine stops. In this manner, 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 volatilizer 30.

[0044] When the medicinal liquid in the container 10 runs out or becomes low, the medicinal liquid can be replenished. That is, after the cover member 20 is removed 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.

[0045] <3. Features> According to the chemical solution volatilization device configured as above, the following effects can be obtained. (1) Since the third groove 44 extending downward from the lower end of each volatilization hole 42 is formed on the outer circumferential surface of the cover member 20, even if the liquid medicine leaks from the volatilization hole 42 when, for example, the container 10 is replaced or the liquid medicine volatilization device is moved, the liquid medicine collects in the third groove 44 located below, so that the leaked liquid medicine is prevented from being noticeable. Furthermore, since the liquid medicine can be held in the third groove 44, the surroundings of the liquid medicine volatilization device can be prevented from being soiled by the liquid medicine.

[0046] (2) Since the fourth groove 45 is formed at the lower end of the side wall 4 of the cover member 20, even if the liquid medicine leaks from the volatilization hole 42 and flows downward along the side wall 4 when, for example, the container 10 is replaced or the liquid medicine volatilization device is moved, the liquid medicine can be held in the fourth groove 45. Therefore, it is possible to prevent the leaked liquid medicine from being noticeable. Furthermore, since the liquid medicine can be held in the fourth groove 45, it is possible to prevent the surroundings of the liquid medicine volatilization device from being soiled by the liquid medicine.

[0047] (3) The lower end of the discharge pipe 22 is in the recess 31, and the liquid medicine is discharged from the container 10 only when the liquid medicine level in the recess 31 is lower than the lower end of the discharge pipe 22, so that the liquid medicine level can be prevented from becoming higher than the lower end of the discharge pipe 22. Therefore, the discharge amount of the liquid medicine can be limited, and a large amount of the liquid medicine can be prevented from being discharged. In addition, since the cover member forms an internal space with the bottom wall portion and the side wall portion, the liquid medicine is prevented from leaking from this internal space, but since the liquid medicine is further accumulated in the recess 31 within this internal space, for example, when the liquid medicine volatilization device is moved, it is further prevented that the liquid medicine flows out of the cover member 20. Therefore, it is possible to prevent the surroundings of the liquid medicine volatilization device from being soiled by the liquid medicine.

[0048] (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 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 that the cover member 20 is attached to the container 10.

[0049] (5) For example, in a type of liquid medicine volatilization device in which a liquid medicine is stored in a container with an opening formed at the top, an absorbent wick is inserted into the opening of the container, and the liquid medicine is sucked up and volatilized by the absorbent wick, a component with a 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 liquid medicine. As a result, it was difficult to freely design the fragrance tone. In contrast, in the liquid medicine volatilization device according to this embodiment, after the liquid medicine is discharged from the bottom of the container 10, the volatilizer 30 absorbs the liquid medicine and volatilizes it, so that the component with a high vapor pressure is prevented from volatilizing first. Therefore, since it is not necessary to mix a large amount of components with low vapor pressure into the liquid medicine, the freedom of designing the fragrance tone can be improved.

[0050] (6) Since the first to third protruding parts 116a to 116c protruding downward are formed on the inner surface of the top wall part 15 of the container body 1, the liquid medicine adhering to the top wall part 15 can be easily collected at the tips of the protruding parts 116a to 116c. As a result, the liquid medicine that has collected at the tips of the protruding parts 116a to 116c can be prevented from falling and remaining attached to the top wall part 15. This can prevent the liquid medicine from being unable to be discharged even though it remains in the container 10.

[0051] In particular, in this embodiment, since the protrusions 116a to 116c are adjacent to each other in a concentric circle shape, the chemical solution adhering between the protrusions 116a to 116c can be easily guided to any one of the protrusions 116a to 116c. Moreover, since the second and third protrusions 116b, 116c are formed in a continuous circular shape, the chemical solution adhering to any position on the top wall 15 can be easily guided to any one of the protrusions 116b, 116c. This can further prevent the chemical solution from remaining attached to the top wall 15.

[0052] <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.

[0053] <4-1> In the above embodiment, the configuration of the third groove 44 provided in the side wall 4 of the cover member 20 is not particularly limited, and the number, shape, and position thereof can be changed as appropriate. For example, the third groove 44 does not have to be formed all the way from the volatilization hole 42 to the lower end of the side wall 4, and it may extend downward from near the lower end of the volatilization hole 42 and not reach the lower end of the side wall 4. Therefore, it is not necessary for the third groove 44 to be completely connected to the lower end of the volatilization hole 42, and it is sufficient that the third groove 44 is formed with a small gap.

[0054] In addition, the third grooves 44 do not have to extend completely vertically, and may be slightly inclined. Furthermore, the width of the third grooves 44 is not particularly limited, and may not be the same as the width of the evaporation holes 42. Therefore, the width of the third grooves 44 may be narrower or wider than the width of the evaporation holes 42. In addition, the widths of all the third grooves 44 do not have to be the same, and may be different.

[0055] The first, second and fourth grooves 114, 43 and 45 other than the third groove 44 are not essential, and even with only the third groove 44, the leaked liquid medicine can be held, so that the surroundings of the device can be prevented from becoming dirty. However, if the fourth groove 45 is provided, it is preferable because it can hold more liquid medicine.

[0056] When the fourth groove 45 is provided, it does not have to be formed over the entire circumferential direction, and it may be formed in a part of the circumferential direction. In this case, it is preferable to form the fourth groove 45 at least below the part where the volatilization hole 42 is formed. In addition, the vertical position of the fourth groove 45 is not particularly limited, and it may be between the lower end of the side wall portion 4 and the volatilization hole 42. Therefore, it may intersect with the third groove 44. In addition, a plurality of fourth groove portions 45 may be formed at predetermined intervals in the circumferential direction. In this case, the vertical heights of all the fourth grooves 45 may be the same or may be shifted. In addition, a plurality of fourth grooves 45 extending over the entire circumference of the side wall portion 4 can be formed. Furthermore, the fourth groove 45 does not have to extend completely horizontally, and may be slightly inclined. In addition, the third groove 44 may not be connected to the fourth groove 45, a gap may be formed between the two, and further, a part of the third grooves 44 may be connected to the fourth groove 45.

[0057] 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 not to 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. Furthermore, regardless of the positions of the third groove 44 and the fourth groove 45, if the bottom wall portion 3 protrudes, the chemical solution volatilization device can be stably held, and if the chemical solution leaks from the third groove 44 or the fourth groove 45, the chemical solution can be attached. From this viewpoint, it is preferable that the bottom wall portion 3 protrudes.

[0058] The position, shape, and number of the volatilization holes 42 are not particularly limited and can be changed as appropriate. However, if the volatilization holes 42 are formed in the shape of elongated holes, it is preferable because if the liquid medicine leaks downward from the volatilization holes 42, the amount of the liquid medicine leaking can be restricted. On the other hand, since the volatilization holes 42 are formed long in the vertical direction, the volatilization of the liquid medicine is not hindered.

[0059] Other configurations of the cover member 20 are not particularly limited as long as it covers at least the lower end of the container 10 and has a vaporization hole.

[0060] <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. However, 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.

[0061] <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.

[0062] <4-4> The shape of the container 10 is not particularly limited, as long as it has at least an internal space capable of accommodating the liquid medicine, 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 modified as appropriate. Furthermore, the valve member 23 attached to the discharge pipe 22 is not necessarily required, but is preferably provided from the viewpoint of preventing leakage of the liquid medicine during assembly. However, the structure and type of the valve member are not particularly limited as long as it is normally closed and opens during assembly.

[0063] <4-5> 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. However, 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.

[0064] <4-6> 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.

[0065] <4-7> The liquid chemical 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.

[0066] The container 10 and the 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. [Explanation of symbols]
