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

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

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

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

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

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

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

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

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

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

<1-1-2. Lid member>
Next, the lid member 2 will be described with reference to Figs. 6 and 7. Fig. 6 is a perspective view of the lid member, and Fig. 7 is a cross-sectional view of the lid member. As shown in Figs. 6 and 7, the lid member 2 includes a cylindrical side wall portion 21 and a bottom wall portion 22 that closes the lower portion of the side wall portion 21. A female screw 211 is formed on the inner surface of the side wall portion 21, and the female screw 211 and the male screw 132 of the discharge portion 13 of the container body 1 are screwed together. A circular through hole 221 is formed in the bottom wall portion 22, and a cylindrical first liquid suction member 23 and a second liquid suction member 24 are inserted into the through hole 221. The first liquid suction member 23 and the second liquid suction member 24 are attached to a seal member 25 that liquid-tightly closes the through hole 221. Therefore, as described below, the liquid medicine 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 liquid medicine from the outside is sucked up.

The first liquid-absorbing member 23 is formed shorter than the second liquid-absorbing member 24. The material from which the first liquid-absorbing member 23 and the second liquid-absorbing member 24 are formed is not particularly limited as long as it is a material that can absorb the chemical solution. 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, etc. mixed with a binder.

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

As shown in Figures 8 to 10, the cover member 20 has a disk-shaped bottom wall portion 3 and a cylindrical side wall portion 4 that rises upward from a position slightly inside the outer edge of the bottom wall portion 3, and the drug solution can be stored in the space surrounded by these. In other words, this space constitutes the storage portion 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 formed in a shape that fits along the lower end of the first portion 111. In addition, in order to removably fix the cover member 20 and the container 10, a pair of circumferentially extending protrusions 41 are formed on the inner surface near the upper end of the side wall portion 4 so as to extend in the circumferential direction. These protrusions 41 are removably fitted into the mounting grooves 119 formed in the second portion 112 of the container body 1.

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

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

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

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

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

<1-3. Volatilization>
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.

As shown in Figures 11 and 12, the volatilizer 30 is adapted to be attached to the lid member 2 and comprises 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 roughly the same as the outer diameter of the lid member 2. The base plate 51 is formed with a circular through hole 511 at a position slightly offset from the center, and the second liquid absorbing member 24 of the lid member 2 is inserted into this through hole 511, which has an inner diameter larger than the outer diameter of the second liquid absorbing member 24.

As shown in FIG. 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 extends downward from the through hole 511 of the substrate 51. The second liquid absorbing member 24 does not contact the substrate 51.

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

The material of the volatilizer 30 is not particularly limited as long as it is capable of absorbing the liquid medicine and volatilizing it to the outside. For example, it can be made of the same material as the liquid-absorbing members 23 and 24 described above.

<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 other components such as a deodorant component, an insect repellent component, an antibacterial component, etc. Such functional components may be either oil-based or water-soluble.

Such a chemical solution can also be produced by mixing, for example, surfactants, fragrances, preservatives, UV absorbers, and water.

2. Assembly and use of chemical volatilization device
Next, the 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 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. 13, when the attachment of the cover member 20 is completed, the second liquid suction member 24 is configured to contact the upper surface of the bottom wall portion 3 of the cover member 20. However, as long as the chemical solution can be sucked up as described later, it does not necessarily have to be in contact with the bottom wall portion 3.

Next, the volatilization of the medicinal liquid will be explained. As shown in FIG. 13, the medicinal liquid is discharged from the container body 1 to the outside via the first liquid suction member 23 and the second liquid suction member 24. However, since the first liquid suction member 23 is in contact with the volatilizer 30, the medicinal liquid moves to the volatilizer 30 via the first liquid suction member tube 23. The medicinal liquid absorbed in the volatilizer 30 is then volatilized, and is further volatilized from the volatilization hole 42 to the outside of the medicinal liquid volatilization device. This makes it possible to obtain an aromatic effect due to the functional components.

However, if an excessive amount of medicinal liquid is discharged from the container body 1, the volatilizer 30 may not be able to retain the medicinal liquid and it may leak downward. The medicinal liquid that leaks from the volatilizer 30 accumulates in the internal space of the cover member 20, as shown in FIG. 13. Here, the second liquid suction member 24 extending from the container 10 reaches the upper surface of the bottom wall portion 3, and is therefore immersed in the medicinal liquid that has accumulated in the internal space. Therefore, the medicinal liquid that has accumulated in the internal space is sucked up by the second liquid suction member 24 and returned to the container 10.

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

<3. Features>
According to the chemical solution volatilization device configured as above, the following effects can be obtained.
(1) In the cover member 20, an internal space surrounded by the bottom wall portion 3 and the side wall portion 4 is formed, so that the liquid medicine that cannot be retained in the volatilizer 30 and leaks can be stored in the internal space. In addition, 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 portion 3) and is immersed in the accumulated liquid medicine, so that the liquid medicine can be sucked up and returned to the container body 1. Therefore, even if an excess liquid medicine is discharged from the container 10 and accumulates in the cover member 20, it can be returned to the container body 1, so that waste of the liquid medicine can be suppressed.

In addition, since the liquid medicine accumulated in the internal space can be returned to the container body 1, it is possible to prevent the amount of liquid medicine accumulated in the internal space from increasing. Therefore, for example, when the liquid medicine volatilization device is moved, it is possible to prevent the liquid medicine from flowing out of the cover member 20 to the outside. This makes it possible to prevent the surroundings of the liquid medicine volatilization device from becoming dirty with the liquid medicine.

(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 liquid medicine from the container 10 during assembly, while at the same time, when the cover member 20 is attached to the container 10, the valve member 23 is pressed by the protrusion 32 to open, allowing the liquid medicine to volatilize at the same time as the cover member 20 is attached to the container 10.

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

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

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

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

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

<4-1>
The shapes of the first liquid suction member 23, the second liquid suction member 24, and the volatilizer 30 are not particularly limited. That is, it is sufficient that the chemical solution discharged through the first liquid suction member 23 can move to the volatilizer 30, and the second liquid suction member 24 can suck up the chemical solution accumulated in the internal space of the cover member 20. For example, as shown in FIG. 14, the first liquid suction member 23 and the substrate 51 are formed in a ring shape so that they are in contact with each other. Then, the second liquid suction member 24 can be formed so as to extend downward through the first liquid suction member 23 and the substrate 51. At this time, the first liquid suction member 23 and the substrate 51 can be integrated.

<4-2>
The volatilizer 30 does not have to be two parts 51 and 52 as described above, but in order to efficiently volatilize the liquid medicine 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 liquid medicine and volatilize it to the outside. The volatilizer 30 can also be composed of a plurality of materials.

<4-3>
The shape of the container 10 is not particularly limited as long as it has an internal space capable of containing at least the liquid medicine and is capable of sucking or discharging the liquid medicine from the discharge portion 13 to the outside via the first and second liquid suction members 23, 24.

<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 an internal space for storing the chemical solution. However, the position of the internal space for storing the chemical solution is not particularly limited and may be anywhere in the cover member 20. In addition, the shape of the cover member 20, including the shape and position of the volatilization hole 42 and the presence or absence of the grooves 43 to 45, can be modified in various ways. For example, 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. In addition, the cover member 20 may have a structure in which a part of the volatilization body 30 is exposed to the outside.

<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.

<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, but these three parts can be further composed of multiple parts as long as they have a configuration that performs these functions in terms of external appearance. In that case, the parts can be formed from different materials.

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