[0014] Hereinafter, a chemical solution volatilization device according to one embodiment of the present invention will be described with reference to the drawings.

[0015] <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.

[0016] <1-1. Container> Fig. 2 is a side view of the container. As shown in Fig. 2, the container 10 includes a container body 1 having an opening at the bottom end thereof and containing a medicinal solution, and a lid member 2 that closes the opening at the bottom end of the container body 1. These members will be described in detail below.

[0017] <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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] <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 side wall portion 21 and a bottom wall portion 22 that closes the lower portion of the side wall portion 21. A female thread 211 is formed on the inner surface of the side wall portion 21, and this female thread 211 is adapted to be threadedly engaged with a male thread 132 of the discharge portion 13 of the container body 1. A circular through-hole 221 is formed in the bottom wall portion 22, and a cylindrical first liquid absorbing member 23, a second liquid absorbing member 24, and an exhaust pipe 29 are inserted through this through-hole 221. The first liquid absorbing member 23, the second liquid absorbing member 24, and the exhaust pipe 29 are attached to a seal member 25 that liquid-tightly closes the through-hole 221. The exhaust pipe 29 is formed to a length that extends to the vicinity of the top wall portion 15 of the container body 1 when the lid member 2 is attached to the container body 1. As will be described later, the chemical solution in the container 10 is discharged to the outside of the container via the first liquid suction member 23 and the second liquid suction member 24, or the chemical solution from the outside is sucked up. Also, as will be described later, the air inside the container 10 is discharged to the outside by the exhaust pipe 29.

[0025] The first liquid-absorbent member 23 is formed to be shorter than the second liquid-absorbent member 24. The material from which the first liquid-absorbent member 23 and the second liquid-absorbent member 24 are formed is not particularly limited as long as it is a material that can absorb chemical solutions. For example, various materials such as paper and cloth can be used, and nonwoven fabric is preferable, and the nonwoven fabric can be formed from pulp, polyester, rayon, or the like mixed with a binder.

[0026] The material from which the exhaust pipe 29 is made is not particularly limited, but it can be made of various materials such as resin material and metal.

[0027] <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.

[0028] 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. The space enclosed by these components is capable of storing a liquid medicine. In other words, this space constitutes the reservoir of the present invention. 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 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 portion 4. These ridges 41 are detachably fitted into mounting grooves 119 formed in the second portion 112 of the container body 1.

[0029] 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.

[0030] 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.

[0031] 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 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 unity in design is achieved by aligning the multiple grooves 114, 43, 44 and the vaporization holes 42 in the vertical direction.

[0032] 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.

[0033] 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 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.

[0034] <1-3.Volatile bodies> Next, the volatilizer will be described with reference to Figures 11 and 12. Figure 11 is a perspective view of the volatilizer seen from above, and Figure 12 is a side view of the volatilizer attached to a container.

[0035] 11 and 12, the volatilizer 30 is attached to the lid member 2 and includes a rectangular plate-like base plate 51 and a pair of rectangular volatilizer plates 52 extending upward from opposing sides of the base plate 51. The outer diameter of the base plate 51 is approximately the same as the outer diameter of the lid member 2. A circular through-hole 511 is formed in the base plate 51 at a position slightly offset from the center, and the second liquid absorbing member 24 and the exhaust pipe 29 of the lid member 2 are inserted through this through-hole 511.

[0036] 12, when the volatilizer 30 is attached to the lid member 2, the bottom wall portion 22 of the lid member 2 faces the upper surface of the substrate 51. At this time, the first liquid absorbing member 23 contacts the substrate 51, and the second liquid absorbing member 24 and the exhaust pipe 29 extend downward from the through-hole 511 of the substrate 51. Of these, the second liquid absorbing member 24 does not contact the substrate 51.

[0037] 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.

[0038] The volatilizer 30 is not particularly limited as long as it is made of a material that can absorb the chemical solution and volatilize it to the outside. For example, it can be made of the same material as the liquid-absorbing members 23 and 24 described above.

[0039] <1-4. Chemical Solution> The medicinal solution contained in the container 10 contains an aromatic component as a functional component. However, it may also contain various other components such as a deodorizing component, an insect repellent component, and an antibacterial component. Such functional components may be either oil-based or water-soluble.

[0040] Such a chemical solution can be produced by mixing, for example, a surfactant, a fragrance, a preservative, a UV absorber, water, and the like.

[0041] <2. Assembly and use of chemical volatilization device> Next, assembly of the chemical solution volatilization device will be described with reference to FIG. 13. FIG. 13 is a cross-sectional view of the chemical solution volatilization device. First, the chemical solution 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. This brings the upper end of the exhaust pipe 29 to the vicinity of the top wall 15 of the container body 1. The distance between the upper end of the exhaust pipe 29 and the top wall 15 of the container body 1 is preferably, for example, 0.1 to 10 mm. 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 from below, to which the volatilizer 30 is attached. As shown in FIG. 13, when the attachment of the cover member 20 is complete, the second liquid absorbing member 24 is configured to contact the upper surface of the bottom wall 3 of the cover member 20. However, as long as the chemical solution can be absorbed, as described below, it does not necessarily have to contact the bottom wall 3.

[0042] Next, the volatilization of the liquid medicine will be described. As shown in Figure 13, the liquid medicine is discharged from the container body 1 to the outside via the first liquid-absorbing member 23 and the second liquid-absorbing member 24. However, since the first liquid-absorbing member 23 is in contact with the volatilizer 30, the liquid medicine moves to the volatilizer 30 via the first liquid-absorbing member pipe 23. The liquid medicine absorbed in the volatilizer 30 is then volatilized, and 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] However, if an excessive amount of chemical liquid is discharged from the container body 1, the chemical liquid may not be retained in the volatilizer 30 and may leak downward. The chemical liquid leaking from the volatilizer 30 accumulates in the internal space of the cover member 20, as shown in FIG. 13. Here, the second liquid-absorbing member 24 extending from the container 10 reaches the upper surface of the bottom wall portion 3, and is therefore immersed in the chemical liquid accumulated in the internal space. Therefore, the chemical liquid accumulated in the internal space is sucked up by the second liquid-absorbing member 24 and returned to the container 10.

[0044] Furthermore, as use progresses, the level of the chemical solution in container body 1 decreases, increasing the amount of air in the internal space of container body 1. As shown in Fig. 13, exhaust pipe 29 extends up to the vicinity of top wall 15 of container body 1, so that air that accumulates in the upper part of container body 1 can be discharged to the outside via exhaust pipe 29.

[0045] 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.

[0046] <3. Features> According to the chemical solution volatilization device configured as above, the following effects can be obtained. (1) As described above, the amount of air in the internal space of container body 1 increases with use. Depending on changes in temperature, this air may press against the medicinal liquid in container 10, resulting in excessive discharge of the medicinal liquid. In contrast, in this embodiment, container 10 is provided with exhaust pipe 29. Therefore, for example, when the air inside container 10 expands, the air can be discharged to the outside via exhaust pipe 29, thereby preventing the expanded air from pressing against the medicinal liquid. As a result, excessive discharge of the medicinal liquid can be prevented.

[0047] (2) The cover member 20 has an internal space surrounded by the bottom wall 3 and the side wall 4, so that any leaked chemical liquid that cannot be retained by the volatilizer 30 can be collected in the internal space. Furthermore, the second liquid-absorbing member 24 extending from the container body 1 extends to the bottom surface of the internal space (the upper surface of the bottom wall 3) and is immersed in the collected chemical liquid, so that it can suck up the chemical liquid and return it to the container body 1. Therefore, even if excess chemical liquid is discharged from the container 10 and collects in the cover member 20, it can be returned to the container body 1, preventing the chemical liquid from being wasted.

[0048] Furthermore, since the chemical liquid accumulated in the internal space can be returned to the container body 1, it is possible to prevent the amount of chemical liquid accumulated in the internal space from increasing. Therefore, for example, when the chemical liquid volatilization device is moved, it is possible to prevent the chemical liquid from flowing out from the cover member 20 to the outside. Therefore, it is possible to prevent the surroundings of the chemical liquid volatilization device from being soiled by the chemical liquid.

[0049] (3) 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.

[0050] (4) 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.

[0051] (5) 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.

[0052] (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.

[0053] 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.

[0054] <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.

[0055] <4-1> In the above embodiment, the exhaust pipe 29 protrudes downward from the lid member 2 and further extends downward through the volatilizer 30, but the configuration of the exhaust pipe is not particularly limited. That is, as long as it can exhaust the air inside the container 10 to the outside, it may be configured to extend to the outside from a location other than the lid member 2. However, from the viewpoint of ease of manufacturing, it is preferable to provide the exhaust pipe on the lid member 2.

[0056] <4-2> The shapes of the first liquid-absorbing member 23, the second liquid-absorbing member 24, and the volatilizer 30 are not particularly limited. That is, it is sufficient that the chemical solution discharged through the first liquid-absorbing member 23 can move to the volatilizer 30, and that the second liquid-absorbing member 24 can absorb the chemical solution accumulated in the internal space of the cover member 20. For example, as shown in FIG. 14, the first liquid-absorbing member 23 and the substrate 51 are formed in an annular shape so that they are in contact with each other. The second liquid-absorbing member 24 can then be formed to extend downward while passing through the first liquid-absorbing member 23 and the substrate 51. In this case, the first liquid-absorbing member 23 and the substrate 51 can also be integrated.

[0057] <4-3> The volatilizer 30 does not have to be two parts 51, 52 as described above, but it is preferable that a portion of the volatilizer 30 extends to a position facing the volatilization hole 42 in order to efficiently volatilize the chemical solution to the outside of the device. 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. The volatilizer 30 can also be composed of multiple materials.

[0058] <4-4> The shape of the container 10 is not particularly limited as long as it has an internal space that can at least contain the liquid medicine and can discharge or suck the liquid medicine from the discharge part 13 to the outside via the first and second liquid absorbing members 23, 24.

[0059] <4-5> 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 an internal space for storing the chemical solution. However, the location of the internal space for storing the chemical solution is not particularly limited, and it may be located anywhere within the cover member 20. Furthermore, 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. Furthermore, the cover member 20 may have a structure in which a portion of the volatilizer 30 is exposed to the outside.

[0060] <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.

[0061] <4-7> In the above embodiment, the directional component of the chemical solution is released to the outside via the first liquid-absorbing member 23 and the volatilizer 30, but this is not limiting and any configuration may be used as long as the chemical solution is impregnated into the volatilizer 30 and can be volatilized to the outside. From this perspective, the second liquid-absorbing member 24 is not necessarily required.

[0062] Alternatively, for example, the chemical solution can be discharged without using a liquid-absorbing member. This embodiment will be described with reference to Figs. 15 to 17. As shown in Fig. 15, a discharge pipe 22 extending downward is attached to the cover member 2. Furthermore, a through-hole 511 through which the discharge pipe 22 is inserted is formed in the base plate 51 of the volatilizer 30, and a liquid-absorbing plate 53 is attached to the base plate 51 so as to sandwich the discharge pipe 22. This liquid-absorbing plate is formed so as to extend slightly downward beyond the discharge pipe. Furthermore, an exhaust pipe 29 is formed so as to extend outward from the side of the discharge pipe 22.

[0063] 16, a recess 31 into which the discharge pipe 22 is inserted is formed on the upper surface of the bottom wall portion 4 of the cover member 20. When the cover member 20 is attached to the container 10, the discharge pipe 22 is inserted into the recess 31, but because the liquid absorbing plate 53 extends below the discharge pipe 22, a gap is formed between the discharge pipe 22 and the bottom surface of the recess 31.

[0064] As shown in Figure 16, the medicinal liquid is discharged from the discharge pipe 22 and accumulates in the recess 31, but because the liquid-absorbing plate 53 of the volatilizer 30 is in contact with the bottom surface of the recess 31, the medicinal liquid accumulated in the recess 31 is absorbed by the liquid-absorbing plate 53. The absorbed medicinal liquid moves to the volatilization plate 52 via the liquid-absorbing plate 53 and the substrate 51, is evaporated from the volatilization plate 52, and is further evaporated to the outside of the medicinal liquid evaporation device through the evaporation holes 42. This allows the aromatic effect of the functional ingredients to be obtained.

[0065] Incidentally, when the chemical solution is stored in recess 31 and the lower end of discharge pipe 22 is immersed in this chemical solution, the inside of discharge pipe 22 is filled with the chemical solution, preventing air from entering, and thus discharging of the chemical solution stops. However, when the chemical solution stored in recess 31 is absorbed by volatilizer 30 and the level of the chemical solution in recess 31 drops, causing the level of the chemical solution to fall below the lower end of discharge pipe 22—that is, when the level of the chemical solution is positioned in the gap between the lower end of discharge pipe 22 and the bottom surface of recess 31 as shown in FIG. 17 —air enters from the lower end of discharge pipe 22, pushing the chemical solution inside container 10 and discharging the chemical solution from discharge pipe 22. Thereafter, when the discharged chemical solution accumulates in recess 31 and the level of the chemical solution rises again above the lower end of discharge pipe 22, air cannot enter the discharge pipe, and discharging of the chemical solution stops. In this way, while the discharge and stopping of the chemical solution is repeated, the chemical solution is evaporated to the outside of the chemical solution volatilization device by the volatilizer 30. Therefore, the amount of chemical solution discharged can be limited, and the discharge of a large amount of chemical solution can be prevented.

[0066] Instead of the recess 31, a groove for collecting the chemical solution may be formed, and the lower ends of the discharge pipe 22 and the liquid absorbing plate 53 may be in contact with this groove. A valve member may be attached to the discharge pipe 22 as needed, so that when the container 10 is attached to the cover member 20, the valve member opens, allowing the chemical solution to be discharged. This closes the discharge pipe 22 with the valve member before the cover member 20 is attached, preventing leakage of the chemical solution. In the embodiments shown in FIGS. 15 to 17, the configuration of the exhaust pipe 29 is not particularly limited. For example, the location where the exhaust pipe 29 is attached is not particularly limited. The periphery of the recess 31 or the groove on the upper surface of the bottom wall 3 may be flat, but at least a portion of the periphery may be inclined. That is, at least a portion of the surface surrounding the recess 31 or the groove may be an inclined surface that slopes toward the recess 31 or the groove. This allows the chemical solution adhering to the periphery of the recess 31 or the groove to be collected in the recess 31 or the groove.

[0067] <4-8> The chemical solution volatilization device of the above embodiment is composed of three parts: the container 10, the cover member 20, and the volatilization body 30. 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.

[0068] 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]
