[0017] Hereinafter, a chemical solution volatilization device according to one embodiment of the present invention will be described with reference to the drawings.

[0018] <1. Overall configuration of chemical solution volatilization device> Fig. 1 is a perspective view of a chemical solution volatilization device according to this embodiment. As shown in Fig. 1, this chemical solution volatilization device includes a container 10 that contains a chemical solution, a cover member 20 that covers the lower end of the container 10, and a volatilizer (omitted in Fig. 1) 30 that is contained between the container 10 and the cover member 20 and that volatilizes the chemical solution discharged from the container 10. These components will be described in detail below.

[0019] <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 and containing a medicinal solution, 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.

[0020] <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 as seen from above, and Fig. 5 is a cross-sectional view of the container body. As shown in Figs. 3 to 5, container body 1 comprises a cylindrical main body portion 11, a connecting portion 12 connected to the lower end of main body portion 11, and a cylindrical discharge portion 13 having a smaller diameter than main body portion 11 and extending downward from the lower end of connecting portion 12, all of which are integrally formed. 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.

[0021] The side wall 110 is made up 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.

[0022] 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. Furthermore, first grooves 114 extending over the entire vertical direction are formed in the first portion 111 at predetermined intervals in the circumferential direction. The lower edge of the first portion 111 is formed in a circular shape, with a pair of portions facing each other across the axis protruding downward in an arc-like shape. Hereinafter, these portions will be referred to as lower protrusions 117. Furthermore, between the two lower protrusions 117, a pair of portions protruding upward in a slight arc-like shape is formed. Hereinafter, these portions will be referred to as upper protrusions 118. Thus, the lower edge of the first portion 111 is formed by a curve smoothly connecting the pair of lower protrusions 117 and the pair of upper protrusions 118.

[0023] 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, a pair of mounting grooves 119 extending in the circumferential direction are formed in the second portion 112 at a predetermined interval. These mounting grooves 119 are each formed at a position corresponding to the above-mentioned lower protrusion 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.

[0024] 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 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 thread 132 is formed near the lower end of the outer circumferential surface of the discharge portion 13.

[0025] As shown in Figures 4 and 5, the top wall 115 is circular in plan view, and a first protrusion 116a that protrudes downward is formed at the center of the inner surface of the top wall 115. The first protrusion 116a is formed to have an arc-shaped cross section. 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. Recesses 116e to 116g are formed on the upper surface of the top wall 115 to correspond to the protrusions 116a to 116c.

[0026] The container body 1 has an internal space surrounded by the main body part 11, the connecting part 12, and the discharge part 13, and the medicinal liquid is stored in this internal space.

[0027] <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. 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 bottom wall portion 212 that closes the bottom 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 adapted to threadably engage with 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 bottom wall portion 212, and the discharge pipe 22 is connected to this through-hole.

[0028] 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, opening the through hole.

[0029] <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 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.

[0030] As shown in FIGS. 8 to 10 , the cover member 20 includes a disk-shaped bottom wall 3 and a cylindrical side wall 4 that rises upward from a position slightly inside the outer edge of the bottom wall 3. When the cover member 20 is attached to the container 10, the upper end of the side wall 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 4 contacts the second portion 112. Therefore, the upper end of the side wall 4 is shaped to fit along the lower end of the first portion 111. Furthermore, to detachably fasten the cover member 20 to the container 10, a pair of circumferentially extending ridges 41 are formed on the inner surface near the upper end of the side wall 4. These ridges 41 are detachably fitted into mounting grooves 119 formed in the second portion 112 of the container body 1.

[0031] 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 via these volatilization holes 42. As will be described later, the chemical solution is allowed to volatilize to the outside through these volatilization holes 42.

[0032] The multiple evaporation holes 42 have approximately the same length in the vertical direction, and are formed at predetermined intervals along the circumferential direction of the side wall portion 4. The upper ends of the evaporation holes 42 lined up in this manner are positioned so that they are spaced apart by the same length as the upper ends of the side wall portion 4. Therefore, the multiple evaporation holes 42 lined up in the circumferential direction are also lined up so that their positions in the vertical direction change to match the upper ends of the side wall portion 4.

[0033] A second groove 43 extending in the vertical direction is formed between the upper end of each vaporization 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 vaporization 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 of the cover member 20, the vaporization holes 42, and the third groove 44 are arranged so as to be aligned in the vertical direction. In this way, a sense of design unity is achieved by aligning the multiple grooves 114, 43, 44 and the vaporization holes 42 in the vertical direction.

[0034] The bottom wall 3 has an outer diameter larger than that of the side wall 4. That is, the bottom wall 3 protrudes radially outward from the lower end of the side wall 4. The bottom wall 3 is placed on a predetermined installation surface and supports the entire chemical solution volatilization device.

[0035] 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 third groove 44 are connected to this fourth groove 45.

[0036] A plurality of grooves 31 arranged in a grid pattern are formed in the portion of the upper surface of the bottom wall 3 surrounded by the side wall 4, and function as a space for storing a medicinal solution as described below. The depth of the grooves 31 is substantially constant throughout, and can be, for example, about 0.01 to 3.0 mm. Furthermore, a protrusion 32 is provided near the center of the area where the grooves are formed, and protrudes upward.

[0037] <1-3.Volatile 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 attached to a container.

[0038] As shown in Figures 11 and 12, this volatilizer 30 is attached to the lid 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 plates 52 and the liquid-absorbing plates 53 are both rectangular. The outer diameter of the substrate is approximately the same as the outer diameter of the lid member 2. A rectangular through-hole 511 is formed in the center of the substrate 51, and the discharge pipe 22 of the lid member 2 is inserted into this through-hole 511. The aforementioned liquid-absorbing plates 53 are connected to opposing sides of the through-hole 511. These liquid-absorbing plates 53 are rectangular and extend downward from the through-hole 511.

[0039] 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 absorbing plates 53 are arranged to sandwich the discharge pipe 22 and further extend downward to a position substantially coincident with the lower end of the discharge pipe 22.

[0040] Furthermore, when the volatilizer 30 is attached to the cover member 2, the volatilization 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 volatilization plate 52 is located near the third part 113 of the container body 1. Therefore, the volatilization plate 52 is arranged in a position generally opposite the volatilization hole 42 of the cover member 20.

[0041] The volatilizer 30 is made of a material that can absorb the chemical solution and volatilize it to the outside. It is possible to mold a woven or nonwoven fabric made of synthetic fibers into a predetermined shape using a binder or the like. However, pulp can be mixed in addition to synthetic fibers. In this case, the synthetic fiber content in the volatilizer 30 is preferably, for example, 10% by mass or more, and more preferably 30% by mass or more. Examples of synthetic fibers that can be used include polyethylene terephthalate and nylon. Even when pulp or other fibers other than synthetic fibers are used, it is preferable that at least the surface of the volatilizer 30 be made of synthetic fibers to prevent yellowing, as described below.

[0042] <1-4. Chemical Solution> The medicinal solution contained in the container 10 contains a fragrance component as a functional component. However, various other components, such as deodorizing components, insect repellent components, and antibacterial components, may also be contained. Such functional components may be either oil-based or water-soluble. Furthermore, such functional components may be blended with easily volatilized components with a water vapor pressure of 0.01 to 20 hPa. The blending ratio of such components in the medicinal solution is preferably 0.25 to 2.5% by mass, more preferably 0.5 to 0.75% by mass. Specifically, such components may include, for example, limonene, linalool, linalyl acetate, and α-pinene, which function as fragrances. Furthermore, components with low water vapor pressure may also be contained, such as vanillin and galaclide, which also function as fragrances.

[0043] 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 can be contained in the solution together with or as a fragrance.

[0044] <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 illustrating the discharge of the chemical solution. For ease of explanation, valve member 23 and protrusion 32 are omitted from Figures 16 and 17. First, the chemical solution is placed in container body 1, and the lower end of discharge portion 13 is closed with lid member 2. Next, volatilizer 30 is attached to lid member 2 as described above. Next, cover member 20 is attached to container 10. At this time, cover member 20 is attached so as to cover the container 10 with volatilizer 30 attached from below. As shown in Figure 14, when attachment of cover member 20 is complete, protrusion 41 of cover member 20 fits into attachment groove 119 of container body 1. Furthermore, the lower end of the liquid absorbing plate 53 of the volatilizer 30 and the lower end of the discharge pipe 22 come into contact with the portion of the upper surface of the bottom wall portion 3 where the groove 31 is formed.

[0045] Furthermore, protrusion 32 protruding from the upper surface of bottom wall 3 presses valve element 232 from the lower end of discharge pipe 22, moving valve element 232 upward. This opens the through-hole of valve seat 231, and the chemical solution in container 10 is discharged from discharge pipe 22 and accumulates in groove 31.

[0046] Next, the volatilization of the chemical solution will be described. As shown in Figure 16, the chemical solution is discharged from the discharge pipe 22 and accumulates in the groove 31. However, since the liquid-absorbing plate 53 of the volatilizer 30 is in contact with the groove 31, the chemical solution accumulated in the groove 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 from the volatilization hole 42 to the outside of the chemical solution volatilization device. This allows the aromatic effect of the functional ingredients to be obtained.

[0047] When the chemical solution accumulates in groove 31 and the lower end of discharge pipe 22 contacts the chemical solution in groove 31, the inside of discharge pipe 22 is filled with the chemical solution, preventing air from entering, and discharge of the chemical solution stops. However, when the chemical solution accumulated in groove 31 is absorbed by volatilizer 30 and the level of the chemical solution in groove 31 drops, a gap is formed between the lower end of discharge pipe 22 and the water surface X of the chemical solution in groove 31, as shown in FIG. 17 . Air enters from the lower end of discharge pipe 22, and this air pushes out the chemical solution in container 10, causing the chemical solution to be discharged from discharge pipe 22. Thereafter, the discharged chemical solution accumulates in groove 31. When the level of the chemical solution rises again to the lower end of discharge pipe 22, air cannot enter discharge pipe 22, and discharge of the chemical solution stops. In this way, the discharge and stopping of the chemical solution is repeated, and the chemical solution is volatilized to the outside of the chemical solution volatilization device by volatilizer 30.

[0048] When the medicinal liquid in container 10 runs out or becomes low, it can be replenished with the medicinal liquid. That is, after removing cover member 20 from container 10, lid member 2 is removed from container body 1, and the medicinal liquid is replenished into container body 1 through the opening of discharge part 13.

[0049] <3. Features> According to the chemical solution volatilization device configured as above, the following effects can be obtained. (1) Because the lower end of the discharge pipe 22 is in contact with the groove 31, the chemical solution is discharged from the container 10 only when the level of the chemical solution in the groove 31 drops and a gap forms between the lower end of the discharge pipe 22 and the chemical solution surface, preventing the chemical solution from overflowing the groove. This limits the amount of chemical solution discharged, preventing a large amount of chemical solution from being discharged. Furthermore, because the cover member 20 defines an internal space with the bottom wall portion 3 and the side wall portion 4, leakage of the chemical solution from this internal space is prevented. Furthermore, the chemical solution is further accumulated in the groove 31 within this internal space, further preventing the chemical solution from flowing out of the cover member 20 when, for example, the chemical solution volatilization device is moved. This prevents the area around the chemical solution volatilization device from becoming soiled by the chemical solution.

[0050] Furthermore, because synthetic fibers are used for the volatilizer 30, it is possible to prevent yellowing over time, as occurs with pulp. In other words, it is possible to prevent the appearance of the volatilizer 30 from deteriorating. However, since synthetic fibers have a lower chemical retention capacity than pulp, there is a risk that excessive chemical solution will flow out of the volatilizer 30 if it is absorbed. In contrast, in this embodiment, the chemical solution is retained in the grooves 31 as described above, and is controlled so that the chemical solution is not excessively discharged, thereby preventing the volatilizer 30 from absorbing excessive chemical solution. Therefore, even a volatilizer 30 made of synthetic fibers can be suitably used.

[0051] (2) 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 leakage of the chemical solution 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 and opens, allowing the chemical solution to volatilize at the same time as the cover member 20 is attached to the container 10.

[0052] (3) The third grooves 44 extending downward from the lower ends of the volatilization holes 42 are formed on the outer peripheral surface of the cover member 20. Therefore, even if the chemical solution leaks from the volatilization holes 42 when replacing the container 10, the chemical solution will collect in the third grooves 44 located below, preventing the leaked chemical solution from becoming noticeable. Furthermore, since the chemical solution can be held in the third grooves 44, the area around the chemical solution volatilization device can be prevented from becoming soiled by the chemical solution.

[0053] (4) Because the fourth groove 45 is formed at the lower end of the side wall 4 of the cover member 20, even if the chemical solution leaks from the volatilization hole 42 when replacing the container 10 and flows downward along the side wall 4, the chemical solution can be retained in the fourth groove 45. This prevents the leaked chemical solution from becoming noticeable. Furthermore, because the chemical solution can be retained in the fourth groove 45, it is possible to prevent the area around the chemical solution volatilization device from becoming soiled with the chemical solution.

[0054] (5) For example, in a chemical solution volatilization device of the type in which a chemical solution is stored in a container with an opening at the top, an absorbent wick is inserted into the opening of the container, and the chemical solution is absorbed and volatilized by the absorbent wick, components with high vapor pressures may be absorbed and volatilized first. Therefore, to ensure a certain period of use, it was necessary to blend a large amount of components with low vapor pressures that are less likely to volatilize into the chemical solution. As a result, it was difficult to freely design a 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 pressures from volatilizing first. Therefore, since it is not necessary to blend a large amount of components with low vapor pressures into the chemical solution, the degree of freedom in designing a fragrance tone can be improved.

[0055] (6) Because 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, the liquid medicine adhering to the top wall 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 can be prevented from falling and remaining attached to the top wall 15. This can prevent the liquid medicine from being unable to be discharged even though it remains in the container 10.

[0056] In particular, in this embodiment, because the protrusions 116a to 116c are adjacent to each other in a concentric circle, the chemical solution adhering between the protrusions 116a to 116c can be easily guided to one of the protrusions 116a to 116c. Furthermore, because the second and third protrusions 116b, 116c are formed in a continuous circle, the chemical solution adhering to any position on the top wall 15 can be easily guided to one of the protrusions 116b, 116c. This further reduces the likelihood of the chemical solution remaining attached to the top wall 15.

[0057] <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. Furthermore, the gist of the following modifications can be combined as appropriate.

[0058] <4-1> The shape, position, depth, and number of grooves 31 are not particularly limited, as long as they are configured so that the lower end of the discharge pipe 22 and a portion of the volatilizer 30 come into contact with the portion of the upper surface of the bottom wall 3 where the groove 31 is formed. Therefore, in this regard, for example, there may be only one groove 31. Furthermore, multiple grooves 31 may be arranged in a form other than a grid. Furthermore, the area around the groove 31 on the upper surface of the bottom wall 3 may be flat, but at least a portion of it may be inclined. In other words, at least a portion of the surface around the groove 31 may be an inclined surface that slopes toward the groove 31. This allows the chemical solution adhering to the area around the groove 31 to be collected in the groove 31.

[0059] <4-2> 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 portion of the volatilizer 30 must be arranged so as to be in contact with the chemical solution in the groove 31, and the lower end of the discharge pipe 22 and the volatilizer 30 must be connected via the chemical solution in the groove 31. In this respect, the shape of the volatilizer 30 does not have to be the three parts 51 to 53 described above. However, in order to efficiently volatilize the chemical solution to the outside of the device, it is preferable that a portion of the volatilizer 30 extend to a position facing 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. The volatilizer 30 can also be composed of multiple materials.

[0060] <4-3> The shape of container 10 is not particularly limited, as long as it has at least an internal space capable of containing the chemical solution and has discharge pipe 22 in contact with groove 31 formed at the bottom end of container 10. Therefore, the shape of container 10, including the shape of discharge pipe 22, can be modified as appropriate. Furthermore, valve member 23 attached to discharge pipe 22 is not necessarily required, but is preferably provided from the viewpoint of preventing leakage of the chemical solution during assembly. However, the structure and type of the valve member are not particularly limited as long as it is configured to be normally closed and open during assembly.

[0061] <4-4> 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 groove 31 for storing the chemical 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 grooves 43 to 45, can be modified in various ways. For example, as long as 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 portion of the volatilizer 30 is exposed to the outside.

[0062] <4-5> 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.

[0063] <4-6> 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. However, these three parts can also be composed of multiple parts as long as they have a configuration that performs these functions in terms of external shape. In this case, the parts can be formed from different materials.

[0064] 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]
