However, in FIGS. 1 and 2, the fixture 50 shown in FIG. 3 is omitted. In the following description, unless otherwise specified, front and back, left and right, and up and down directions are defined as shown in FIGS. 1 to 3, and the front side means the front side and the rear side means the back side.

The chemical liquid volatilizer 1 is a device that provides various effects of the chemical liquid to the external space by volatilizing the chemical liquid to the external space. Although not limited thereto, the chemical solution volatilizer 1 of this embodiment is for use in an automobile, and is installed inside the vehicle. More specifically, the chemical solution volatilizer 1 is attached to a louver arranged at an air outlet of an on-vehicle air conditioner. Thereby, the chemical solution volatilizer 1 can efficiently spread the chemical solution inside the car by carrying it on the airflow blown out from the air outlet of the air conditioner.

The chemical solution used here is not particularly limited in type, but typically is a fragrance, a deodorant, an insect repellent, or a mixture thereof. Contains additives such as ingredients and colorants. The solvent contained in the drug solution is appropriately selected depending on the type of additive used, and can be a hydrophilic solvent, a lipophilic solvent, or a mixture thereof. When the medicinal solution contains a fragrance, it is preferable to contain at least a lipophilic solvent as a solvent in order to increase the fragrance intensity. As the hydrophilic solvent, for example, water or ethanol, or a mixture thereof can be used. As the lipophilic solvent, for example, glycol ether or isoparaffinic solvent, or a mixture thereof can be used. Further, the chemical solution may contain a solubilizing agent in order to solubilize functional components such as fragrances, deodorant components, insect repellent components, and colorants.

The chemical solution volatilizer 1 includes an absorber 10 impregnated with a chemical solution (see FIG. 6), a container 20 as a casing that houses the absorber 10, and a fixture 50 that fixes the container 20 near the air outlet of the air conditioner. Equipped with The container 20 is openable and closable and has a front side member 30 and a back side member 40 that are separable from each other. FIG. 4 is a rear view of the front side member 30 alone, and FIG. 5 is a front view of the rear side member 40 alone. With the container 20 in an open state, the absorbent body 10 impregnated with a chemical solution is set at a predetermined position within the internal space S1 of the container 20. FIG. 6 is a perspective view of the front side member 30 in which the absorber 10 is set, viewed from the front side. As shown in FIG. 2, the container 20 has a plurality of vent holes C1 to C3, and when air sent out from the air conditioner passes through these vent holes C1 to C3, the chemical solution is diffused into the vehicle interior. The ventilation holes C1 to C3 communicate the internal space S1 of the container 20 with the external space when the container 20 is in a closed state.

<2. Configuration of each part>
The configuration of each part will be explained in detail below.

<2-1. Absorber>
The absorber 10 is a porous structure and can hold a large amount of liquid medicine inside. The absorbent body 10 of this embodiment is a member that is made of synthetic resin fibers, particularly polyester fibers, has a nonwoven structure, and is processed into a rectangular parallelepiped block.

The absorbent body 10 of this embodiment is manufactured by extrusion molding, as shown in FIG. More specifically, the fiber material filled in the cylinder 100 is extruded from the rectangular extrusion port 101a of the die plate 101 while being heated, thereby forming an elongated fiber mass 102 having a rectangular cross section. Thereafter, the absorbent body 10 is manufactured by cutting the fiber mass 102 into predetermined lengths. The outer surface of the fiber mass 102 is thermally welded by heat transfer from the die plate 101 when it is extruded from the extrusion port 101a of the die plate 101. Therefore, among the outer surfaces of the absorbent core 10, the four side surfaces 10c (see FIG. 6) excluding the upper surface 10a and the lower surface 10b (see FIG. 6), which correspond to the two surfaces exposed when the fiber mass 102 is cut, are as follows: The processed surface has been subjected to surface treatment by thermal welding. Therefore, on the side surface 10c of the absorbent body 10, the fibers of the material are bound together. On the other hand, the upper surface 10a and the lower surface 10b of the absorbent body 10 are unprocessed surfaces that have not been subjected to the above surface treatment. As a result of the above, the penetration of the chemical liquid is suppressed on the side surface 10 c of the absorbent body 10 compared to the upper surface 10 a and the lower surface 10 b of the absorbent body 10 and the inside of the absorbent body 10 . Therefore, in the absorber 10, the chemical liquid is less likely to leak out from the side surface 10c that constitutes the majority of the outer surface thereof, so that the ability to retain the chemical liquid inside is enhanced.

However, the structure of the absorber 10 described above is merely an example, and is not particularly limited as long as it can hold the medical solution. For example, the absorbent body 10 can be made of natural fibers such as plant fibers, animal fibers, and mineral fibers, and as a preferable example, it can be made of pulp (paper) extracted from wood, grass, etc. Further, the absorbent body 10 may have a woven structure instead of a non-woven structure, or may be a foam molded product.

<2-2. Container>
As described above, the container 20 has the front side member 30 and the back side member 40, and can be opened and closed by attaching and detaching the back side member 40 to and from the front side member 30. Although not limited thereto, both the front side member 30 and the back side member 40 are made of synthetic resin such as polypropylene. In this embodiment, the front side member 30 is integrally constructed as one component and cannot be separated, and the rear side member 40 is also integrally constructed as one component and cannot be separated. ing. Moreover, the front side member 30 and the back side member 40 of this embodiment are transparent or translucent.

Although not limited thereto, as shown in FIG. 1, the container 20 of this embodiment has a shape imitating a human in order to enhance the design. The front side member 30 has a shape in which a head, a torso, both hands, and both legs are connected, and includes a front section 31 and a side section 32 extending in a cylindrical shape from the outer peripheral edge of the front section 31 toward the back side. The front part 31 and the side part 32 are continuous while being smoothly curved near the boundary, and the part of the front side member 30 corresponding to the head is approximately hemispherical.

As shown in FIG. 4, the front side member 30 has a pair of side walls 34L and 34R that stand up on the back side from a portion corresponding to the boundary between both hands and the torso on the inner surface of the front section 31. The pair of side walls 34L and 34R, and portions of the front part 31 and side part 32 corresponding to the head, torso, and both legs form an internal space S1 having a shape in which the head, torso, and both legs are connected. The internal space S1 of this embodiment can accommodate the entire absorber 10. A space S2 formed by portions of the front side member 30 corresponding to both hands does not communicate with the internal space S1 and is separated from the internal space S1.

On the other hand, the back side member 40 is a member attached to the front side member 30 so as to cover the above internal space S1. As shown in FIG. 5, the back side member 40 has a back side part 41 and a short outer peripheral part 42 that stands up from the outer peripheral edge of the back side part 41 toward the front side. The back surface portion 41 is a plate-shaped member that connects the head, torso, and both legs. The internal space S1 is closed when the back side member 40 is attached to the front side member 30, and is closed from the outside space except for the ventilation holes C1 to C3.

As shown in FIG. 4, the front side member 30 has a protruding piece 301 that stands up from a portion corresponding to the crotch on the inner surface of the front portion 31 toward the back side. The protruding piece 301 is a plate-shaped member extending in the left-right direction, and has an upper surface 301a forming a substantially horizontal surface. As shown in FIG. 6, the protruding piece 301 receives the absorbent core 10 with its upper surface 301a when the absorbent core 10 is accommodated in the internal space S1. At this time, the upper surface 301a contacts the lower surface 10b of the absorber 10. Moreover, at this time, the left and right side surfaces 10c of the absorber 10 are in contact with the side walls 34L and 34R, respectively. Thereby, the position of the absorber 10 in the internal space S1 is stabilized.

Further, as shown in FIG. 4, the front side member 30 has protruding pieces 302 and 303 that stand up from the inner surface of the front part 31 toward the back side. The protruding pieces 302 and 303 are arranged above the protruding piece 301 in the internal space S1. The protruding piece 302 is a plate-shaped member that extends in the vertical direction mainly in portions corresponding to the head and torso. On the other hand, the protruding piece 303 is a plate-shaped member extending in the left-right direction at a portion corresponding to the boundary between the head and the trunk, and has an upper surface 303a forming a substantially horizontal surface. The protruding pieces 302 and 303 contact the front side surface 10c of the absorbent body 10 when the absorbent body 10 is accommodated in the internal space S1.

On the other hand, as shown in FIG. 5, the back side member 40 has ribs 401 and 402 that stand up from the inner surface of the back part 41 toward the front side. The ribs 401 and 402 are arranged above the protruding piece 301 in the internal space S1. The rib 401 extends in the left-right direction in a portion corresponding to the head and has an upper surface 401a. On the other hand, the rib 402 extends in the left-right direction in a portion corresponding to the vicinity of the boundary between the torso and both legs, and has an upper surface 402a. The ribs 401 and 402 contact the side surface 10c on the back side of the absorbent core 10 when the absorbent core 10 is accommodated in the internal space S1.

Further, as shown in FIG. 5, the back side member 40 has a rib 403 that stands up from the inner surface of the back part 41 toward the front side at a position facing the protruding piece 301 of the front side member 30. The rib 403 extends in the left-right direction at a portion corresponding to the crotch, and has an upper surface 403a. The rib 403 contacts the lower surface 10b of the absorbent core 10 when the absorbent core 10 is accommodated in the internal space S1.

The above protruding pieces 302 and 303 separate the front side surface 10c of the absorber 10 from the inner surface of the front part 31 so that these surfaces do not come into contact with each other. In this sense, hereinafter, the protruding pieces 302 and 303 may be referred to as spacing members 302 and 303, respectively. The spacing members 302 and 303 stand up from the inner surface of the front section 31 and contact the absorbent body 10 accommodated in the internal space S1, thereby inhibiting surface contact between the absorbent body 10 and the front section 31.

Similarly, the above-mentioned ribs 401 and 402 separate the side surface 10c of the absorbent body 10 from the inner surface of the back surface part 41 so that these surfaces do not come into surface contact with each other. In this sense, the ribs 401 and 402 may hereinafter be referred to as spacing members 401 and 402, respectively. The spacing members 401 and 402 stand up from the inner surface of the back surface part 41 and contact the absorbent body 10 accommodated in the internal space S1, thereby inhibiting surface contact between the absorbent body 10 and the back surface part 41.

The above-described spacing members 302, 303, 401, and 402 play a role in increasing the ability of the absorbent body 10 to retain a drug solution. That is, when the absorbent body 10 makes surface contact with the inner surface of the container 20, the chemical solution tends to seep out from the absorbent body 10 at such a contact surface due to capillary phenomenon. In particular, when the temperature inside the vehicle becomes high, the chemical solution may excessively seep out from the absorber 10. In this regard, the spacing members 302, 303, 401, and 402 prevent surface contact between the absorbent core 10 and the inner surfaces of the front section 31 and the back section 41, so that Excessive exudation of the drug solution from the body 10 is prevented. As a result, the chemical solution is prevented from leaking to the outside through the gap formed in the container 20, particularly the minute gap between the front side member 30 and the back side member 40 attached thereto. Therefore, the surrounding environment is prevented from being contaminated by the chemical solution.

In addition, the ribs 401 to 403 described above can collect the chemical solution seeping out of the absorbent body 10 on their respective upper surfaces 401a to 403a, and can return the recovered chemical solution to the absorbent body 10. In other words, the chemical liquid that has seeped out of the absorber 10 is released into the external space along with the airflow formed in the internal space S1, but a portion of it may remain in the internal space S1. In particular, when the vehicle's air conditioner is not in use, it is difficult to form an airflow, so the chemical solution seeping out of the absorber 10 tends to remain in the internal space S1. In addition, if the temperature inside the vehicle becomes high, the chemical solution may seep out excessively. At this time, a part of the chemical liquid that has seeped out from the absorber 10 adheres to the inner surface of the back side member 40, and then drips from the inner surface of the back side member 40, and the upper surfaces 401a to 403a of the ribs 401 to 403, respectively. are collected in. As described above, the ribs 401 and 402 contact the back side surface 10c of the absorbent core 10 housed in the internal space S1, and the rib 403 contacts the lower surface 10b of the absorbent core 10. Therefore, the chemical solution collected on the upper surfaces 401a to 403a is returned to the absorbent body 10 along these surfaces 401a to 403a.

Similarly, the above-described protruding pieces 301 and 303 can also collect the chemical solution seeping out of the absorbent body 10 on the upper surfaces 301a and 303a, respectively, and can return the collected chemical solution to the absorbent body 10. That is, a part of the chemical solution that has seeped out from the absorber 10 may adhere not only to the back side member 40 but also to the inner surface of the front side member 30, and then drips from the inner surface of the front side member 30, and the protruding piece They are collected on the upper surfaces 301a and 303a of 301 and 303, respectively. As mentioned above, the protruding piece 301 contacts the lower surface 10b of the absorbent body 10 housed in the internal space S1, and the protruding piece 303 contacts the front side surface of the absorbent body 10 housed in the internal space S1. 10c. Therefore, the chemical solution collected on the upper surfaces 301a and 303a is returned to the absorbent body 10 along these surfaces 301a and 303a.

As described above, even if the chemical liquid excessively seeps out from the absorbent body 10, the medical liquid can be absorbed into the absorbent body 10 again due to the presence of the ribs 401 to 403 and the protruding pieces 301 and 303. In this sense, the ribs 401 to 403 and the protruding pieces 301 and 303 may be hereinafter referred to as liquid return parts 401 to 403, 301 and 303, respectively. The liquid return parts 401 to 403, 301, and 303 further prevent the chemical liquid from leaking to the outside through the gaps formed in the container 20, especially the minute gaps between the front side member 30 and the back side member 40. It can be prevented.

As shown in FIG. 5, the back side member 40 has a leaf spring-shaped claw part 43 at the upper part of the outer peripheral part 42. As shown in FIG. The claw portion 43 has a substantially V-shape when viewed from the side. On the other hand, as shown in FIG. 4, the front side member 30 has a pair of thin pieces 321L and 321R at the upper part of the side surface part 32. The pair of thin pieces 321L and 321R are arranged with a gap having a constant width in the left-right direction, and the claw portion 43 of the back side member 40 can be received within the gap.

Further, as shown in FIG. 4, the front side member 30 has a pair of protrusions 33L and 33R that stand up on the back side from parts corresponding to both feet on the inner surface of the front part 31. The protrusions 33L and 33R are arranged below the protrusion piece 301 that supports the absorber 10 from below in the internal space S1. On the other hand, as shown in FIG. 5, the back side member 40 has a pair of cylindrical protrusions 44L and 44R that stand up on the front side from parts corresponding to both feet on the inner surface of the back surface part 41. When attaching the back side member 40 to the front side member 30, the central holes of the cylindrical protrusions 44L and 44R of the back side member 40 receive the protrusions 33L and 33R of the front side member 30, respectively, and the protrusions 44L and 44R, The protrusions 33L and 33R engage with each other. At this time, the claw portion 43 of the back side member 40 is pressed and compressed in the vertical direction, and after this is inserted into the gap between the pair of thin pieces 321L and 321R of the front side member 30, the pressing force in the vertical direction is applied. When released, the thin pieces 321L and 321R engage with the claw portion 43. Further, at this time, the inner surface of the side surface portion 32 of the front side member 30 partially contacts the outer surface of the outer peripheral portion 42 of the back side member 40, and the side surface portion 32 and the outer peripheral portion 42 are fitted together. Thereby, the front side member 30 and the back side member 40 are fixed, and the internal space S1 is in a closed state.

As shown in FIGS. 4 and 6, the protrusions 33L and 33R have similar structures. Each of the projections 33L and 33R has a shaft portion 331 extending in the front-rear direction and four thin pieces 332 to 335 arranged at equal intervals around the shaft portion 331. That is, the protrusions 33L and 33R each have a substantially cross shape when viewed from the rear. The thin pieces 332 and 334 extend in the vertical direction. On the other hand, the thin pieces 333 and 335 extend in the left-right direction and have upper surfaces 333a and 335a, respectively, which constitute substantially horizontal surfaces.

Further, the front side member 30 has four thin pieces 322 to 325 that stand up in the left-right direction from portions corresponding to both feet on the inner surface of the side surface portion 32. The thin pieces 322 and 325 protrude inward from a portion corresponding to the outside of both feet on the inner surface of the side surface portion 32. On the other hand, the thin pieces 323 and 324 protrude outward from a portion corresponding to the inside of both feet on the inner surface of the side surface portion 32. The thin pieces 322-325 extend in the left-right direction and have upper surfaces 322a-325a, respectively.

The thin pieces 333, 335, and 322 to 325 described above can receive and hold the medicinal liquid seeped from the absorbent body 10 on their upper surfaces 333a, 335a, and 322a to 325a, respectively. In this sense, hereinafter, the thin pieces 333, 335 and 322-325 may be referred to as liquid receiving portions 333, 335 and 322-325, respectively.

The liquid receiving parts 333, 335, and 322 to 325 are arranged below the protruding piece 301 that supports the absorber 10 from below in the internal space S1. As described above, the lower surface 10b of the absorbent body 10 is an unprocessed surface that has not been subjected to surface treatment to suppress penetration of the chemical solution, and the chemical solution is relatively likely to seep out. However, most of the chemical liquid seeping out from the lower surface 10b is captured by the liquid return section 301 and returned to the absorbent body 10. On the other hand, some of the chemical liquid may fall downward from the liquid return section 301, but such chemical liquid is caught by the liquid receiving sections 333, 335, and 322-325. As a result, the possibility that the medical solution reaches the lower end portions corresponding to the toes of both feet in the internal space S1 is reduced. Therefore, leakage of the chemical liquid to the outside through the gap formed in the container 20, particularly the minute gap between the front side member 30 and the back side member 40, is further prevented.

The entire surface of the inner surface of the back surface portion 41 forms an uneven region in which a fine uneven pattern is formed. FIG. 8 is an example of an enlarged image of an uneven region. Although not limited thereto, as shown in the figure, the uneven pattern of this embodiment is a pattern of many wrinkles. Further, these wrinkles do not form a repeating pattern but are formed randomly. Although not limited thereto, for example, this uneven pattern can be formed by attaching an uneven pattern to the surface facing the inner surface of the back part 41 in a mold for molding the back side member 40. As a result, the concavo-convex pattern of the mold is transferred to the inner surface of the back surface portion 41. Such an uneven pattern can be formed by, for example, texturing.

Since this uneven pattern has a fine structure, it is possible to hold the chemical liquid. FIG. 9 is a photograph taken of a colored liquid applied to a synthetic resin thin plate with a concavo-convex pattern and a similar thin plate without a concave-convex pattern. As is clear from comparing these, the concavo-convex pattern is successful in retaining liquid. As already mentioned, a part of the chemical liquid seeped out from the absorbent body 10 adheres to the inner surface of the back side member 40. Particularly, when the temperature inside the vehicle becomes high and the chemical liquid excessively leaks out, a large amount of the chemical liquid may adhere to the inner surface of the back side member 40. However, at this time, the chemical solution spreads thinly over the inner surface of the back surface portion 41 provided with the above-described uneven pattern, and is captured by the inner surface of the back surface portion 41 . Therefore, the size of the droplet becomes difficult to grow on the inner surface of the back surface portion 41, and the chemical solution becomes difficult to drip downward. Therefore, leakage of the chemical liquid to the outside is further prevented.

As shown in FIG. 5, an opening C1 is formed approximately in the center of the back surface portion 41. A base portion 51 (described later) of the fixture 50 is inserted into the opening C1 at the position indicated by the dotted line and fixed. Even when the base portion 51 is fixed to the opening C1, the opening C1 does not completely close, and the opening C1 remains open. This opening C1 becomes a ventilation hole that communicates the internal space S1 of the container 20 with the external space in a closed state in which the back side member 40 is attached to the front side member 30. Moreover, this opening C1 mainly serves as an introduction port for introducing air sent out from the air conditioner into the internal space S1. Hereinafter, the opening C1 may be referred to as a ventilation hole C1 or an inlet C1.

Further, as shown in FIG. 2, an opening C2 is formed in the upper part of the container 20 near the connecting portion between the claw portion 43 and the thin pieces 321L and 321R. This opening C2 also serves as a ventilation hole that communicates the internal space S1 of the container 20 with the external space in the closed state where the back side member 40 is attached to the front side member 30. Moreover, this opening C2 mainly serves as an outlet for discharging air from the internal space S1. Hereinafter, the opening C2 may be referred to as a ventilation hole C2 or a discharge port C2.

The ventilation hole C2 is arranged above the upper surface 10a of the absorbent body 10 and near the upper surface 10a. As described above, the upper surface 10a of the absorbent body 10 is an unprocessed surface that has not been subjected to surface treatment to suppress penetration of the chemical solution, and the chemical solution is relatively likely to seep out. However, due to the presence of the vent C2 in the vicinity, the chemical solution seeping out from here is likely to be captured by the air current formed in the internal space S1, and is likely to volatilize into the external space. Therefore, leakage of the chemical liquid to the outside is further prevented.

An opening C3 is also formed on the left side of the container 20. This opening C3 also serves as a ventilation hole that communicates the internal space S1 of the container 20 with the external space in the closed state where the back side member 40 is attached to the front side member 30. Moreover, this opening C3 also serves as an exhaust port that mainly discharges air from the internal space S1. Hereinafter, the opening C3 may be referred to as a ventilation hole C3 or a discharge port C3.

The roles of the ventilation holes C1 to C3 are not limited to the roles described above. That is, the roles of the inlet and the outlet may be switched depending on the air volume and direction of the air conditioner. Further, one vent port may serve as both an inlet port and an outlet port.

<2-3. Fixture>
The fixture 50 is a member that fixes the container 20 near the air outlet of the air conditioner so that the back surface 41 of the container 20 faces the air outlet of the air conditioner. Although not limited thereto, the fixture 50 is made of resin such as polypropylene or polyacetal. As shown in FIG. 3, the fixture 50 includes a base portion 51 and a clip portion 52 that extends rearward from the base portion 51 and is fixed to the vicinity of the air outlet of the air conditioner, typically to a louver. In this embodiment, the fixture 50 is integrally constructed as one component and cannot be separated.

The clip portion 52 has a pair of elastic pieces 521 and 522. The elastic pieces 521 and 522 face each other and extend rearward from the base portion 51. The elastic pieces 521 and 522 can be bent by a predetermined amount by elastic deformation so as to be further apart from each other with respect to the portion on the base portion 51 side. Therefore, by applying external force to the elastic pieces 521 and 522, the distance between the elastic pieces 521 and 522 can be increased. By inserting the louver of an air conditioner into the gap between the elastic pieces 521 and 522 thus expanded, the position of the clip portion 52 and, by extension, the entire chemical vaporizer 1 can be fixed.
