<2. Structure of each part>
<2-1. Container>
4A shows a front view of the container 10, and FIG. 4B shows a side view thereof. The container 10 has a container body 11 and a back sheet 12 attached to the container body 11. The container body 11 has a cup portion 111 having an opening 11a on the back surface side, and an annular flange portion 112 continuous to the end portion on the back surface side of the cup portion 111. The flange portion 112 extends circumferentially on the outer side in the radial direction of the cup portion 111 with reference to a central axis (which coincides with the rotation axis A1) extending in the front-rear direction of the cup portion 111. The back sheet 12 is attached to the flange portion 112 so as to close the opening 11a. This sticking can be performed by, for example, heat welding or bonding with an adhesive. The cup portion 111 has a top surface portion 115, a cylindrical outer peripheral portion 116 that extends from the outer peripheral edge of the top surface portion 115 to the back side, and a pedestal portion 114 that is continuous with the rear end of the outer peripheral portion 116. The pedestal portion 114 has a shape including the outer peripheral portion 116 inside when viewed from the front. The pedestal portion 114 has a tubular portion that rises from the inner peripheral edge of the flange portion 112, and a planar portion that extends between the front end portion of the tubular portion and the rear surface end portion of the outer peripheral portion 116. .. Although not limited to this, the top surface portion 115 has a circular shape in a front view, and the outer peripheral edges of the pedestal portion 114, the back sheet 12 and the flange portion 112 have a square shape with rounded corners in a front view. In the present embodiment, the outer peripheral edge of the back sheet 12 and the outer peripheral edge of the flange portion 112 substantially match in front view.

A closed space is formed by the container body 11 and the back sheet 12, and the medicine is stored in the closed space. The drug of the present embodiment is in liquid form. The type of drug is not particularly limited, but is typically a fragrance, a deodorant or an insect repellent, or a mixture thereof. Depending on the purpose of use, a fragrance, a deodorant component, an insect repellent component, a colorant, etc. Additives are included. The solvent contained in the drug is appropriately selected according to the type of additive used, and can be a hydrophilic solvent or a lipophilic solvent, or a mixture thereof. When the drug contains a fragrance, it is preferable to include at least a lipophilic solvent as the solvent in order to enhance 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 drug may contain a solubilizer in order to solubilize functional components such as a fragrance, a deodorant component, an insect repellent component, and a colorant.

The material of the container body 11 is not particularly limited, but may be, for example, a resin such as polyethylene terephthalate or polyethylene. The back sheet 12 is a flexible sheet. The back sheet 12 is configured such that when it is pierced, a hole through which the medicine exudes is formed. FIG. 5 is a cross-sectional view of the backsheet 12 of this embodiment. In this example, the back sheet 12 is composed of a laminate having a volatilization layer 121 and a rupture layer 122 arranged on the container body 11 side of the volatilization layer 121. The volatilization layer 121 is made of a material, here a porous material, that allows a drug to pass through and volatilize. The volatilization layer 121 is made of a material that is less likely to break than the breakage layer 122 when a pressing force is applied to the back sheet 12 from the volatilization layer 121 side and a tensile force for stretching the back sheet 12 is applied. To be done. As the material of the volatilization layer 121 as described above, a porous film such as Teslin (trademark) or Daramic (trademark) can be preferably selected. Further, as the material of the breaking layer 122 as described above, for example, polyethylene, aluminum, or polyethylene terephthalate, or any combination thereof can be selected. A preferable example of the material of the breakage layer 122 is a thin film in which a first polyethylene layer, an aluminum layer, a second polyethylene layer, and a polyethylene terephthalate layer are laminated in this order from the container body 11 side. In the present embodiment, the volatilization layer 121 and the fracture layer 122 are joined only at the outer peripheral portion that overlaps the flange portion 112 in a front view. This joining can be performed by, for example, heat welding or adhesion with an adhesive.

As shown by a dotted line in FIGS. 4A and 4B, a plate 13 is arranged inside the container 10 along the back sheet 12. FIG. 6 is a front view of the plate 13. The plate 13 has substantially the same shape as the space surrounded by the pedestal portion 114, and is housed in the space. Through holes 131 are formed in the plate 13 at predetermined positions, near four corners in a front view in the present embodiment, and through holes 132 are also formed near the center. The inside of the container body 11 is filled with the medicine via the through hole 132. As is clear from the above description, the plate 13 covers the back sheet 12 in the internal space of the container 10. However, in the back sheet 12, the portions corresponding to the through holes 131 and 132 (hereinafter, referred to as uncoated portions) are Not covered by plate 13. The plate 13 is arranged to prevent expansion of the back sheet 12 at a portion other than the uncovered portion when a pressing force is applied to the back sheet 12 from the volatilization layer 121 side. In addition, the plate 13 can prevent the back sheet 12 from being deformed and the breaking layer 122 to be broken when the inside space of the container 10 becomes a negative pressure due to a decrease in environmental temperature. Further, it is possible to prevent the breakage layer 122 from breaking when dropped or due to an external impact. The material of the plate 13 is not particularly limited, but is resin such as polypropylene.

<2-2. Inner case>
FIG. 7 shows an exploded perspective view of the inner case 20. As shown in the figure, the inner case 20 has a front-side member 21 and a back-side member 22 that are removable in the front and rear. FIG. 8 is a perspective view of the front side member 21 viewed from the back side, and FIG. 9 is a perspective view of the back side member 22 viewed from the back side. Although not limited to this, the inner case 20 is made of resin such as polypropylene. In the present embodiment, the front-side member 21 is integrally formed as one part in an inseparable manner, and the back-side member 22 is also integrally formed as a single part in an inseparable manner. ing.

The front member 21 has a first front portion 211 and a cylindrical first side surface portion 212 extending from the outer peripheral edge of the first front portion 211 toward the rear side. On the other hand, the rear surface member 22 has a first rear surface portion 221 that is detachably connected to an end portion on the rear surface side of the first side surface portion 212. The first side surface portion 212 connects the first front surface portion 211 and the first rear surface portion 221 in the front-rear direction.

The first front part 211 has a circular outer peripheral edge when viewed from the front, and has an opening 211a penetrating in the front-rear direction near the center. The opening 211a also has a circular shape that is concentric with the outer peripheral edge of the first front surface portion 211 in a front view. As shown in FIG. 8, a cylindrical inner wall portion 213 standing upright toward the back side is continuous with the first front surface portion 211 along the outer peripheral edge of the opening 221a. The entire cup portion 111 of the container 10 is inserted into the space inside the inner wall portion 213 from the back side. When the container 10 is housed in the inner case 20, the flange portion 112 abuts the inner wall portion 213, so that it is possible to prevent the drug from being evaporated from the space inside the inner wall portion 213. As shown in FIG. 8, the inner wall portion 213 has a circular shape that substantially coincides with the opening 211a in a rear view, but the inner wall portion 213 has four equal radial intervals so that the four corners of the pedestal portion 114 can be received. It has a portion 213a that expands in diameter. Thus, since the inner wall portion 213 and the pedestal portion 114 inserted therein are non-circular, the container 10 rotates with respect to the front member 21 when the cup portion 111 is inserted inside the inner wall portion 213. It cannot rotate around the axis A1.

The first back surface portion 221 is a plate member having an outer peripheral edge of a circular shape, and the outer peripheral edge substantially matches the first front surface portion 211 in a front view. As shown in FIG. 7, on the front surface of the first back surface portion 221, an annular protruding wall 222 stands along the outer peripheral edge slightly inside the outer peripheral edge. On the other hand, as shown in FIG. 8, a step portion 212a is formed on the inner peripheral surface of the first side surface portion 212 along the circumferential direction. More specifically, the first side surface portion 212 has an annular thick portion 214 and a thinner annular thin portion 215 that is continuous with the back surface side of the thick portion 214, and the difference in thickness causes The step portion 212a is formed. The front wall 21 and the rear wall 22 are connected by fitting the protruding wall 222 into the step 212a. An annular protrusion 218 (see FIG. 8) that projects radially inward along the circumferential direction is provided at the rear end of the thin portion 215, and the projecting wall 222 extends along the circumferential direction. An annular protrusion 223 (see FIG. 7) that protrudes outward in the radial direction is provided. When the front-side member 21 and the back-side member 22 are connected, due to elastic deformation of these, the protrusion 218 and the protrusion 223 pass over each other, and the protruding wall 222 is inserted inside the first side surface portion 212. After the insertion, the protrusion 218 and the protrusion 223 are engaged with each other, so that the front side member 21 and the rear side member 22 are maintained in a connected state unless a strong external force is applied, and both members 21 and 22 does not come off unintentionally.

As shown in FIG. 8, the step portion 212a is partially interrupted along the circumferential direction. Then, the front side member 21 is provided with a pair of projecting pieces 216 and 217 which are erected inward from the inner peripheral surface of the first side surface portion 212 at the discontinuous position. On the other hand, as shown in FIG. 7, a claw portion 224 that stands up toward the front side is provided on the upper surface of the protruding wall 222 of the rear member 22. The projecting pieces 216 and 217 function as a housing section that defines a space between which the claw section 224 is inserted. The claw portion 224 is fitted into the space between the projecting pieces 216 and 217 from the back side when the front side member 21 and the back side member 22 are connected. The claw portion 224 and the protruding pieces 216 and 217 function as a rotation restricting portion that restricts the front-side member 21 from rotating relative to the rear-side member 22 around the rotation axis A1 by being engaged with each other. When the claw portion 224 is fitted between the protruding pieces 216 and 217, it is surrounded by the protruding pieces 216 and 217 from both sides around the rotation axis A1. Therefore, the protrusions 216 and 217 can restrict the rotation of the claw portion 224 in the forward and reverse directions around the rotation axis A1. Therefore, the above rotation restricting portion restricts the relative rotation of the front side member 21 with respect to the back side member 22 in the forward direction and the reverse direction.

Although the details will be described later, the outer case 30 is rotatable about the rotation axis A1 in the forward and reverse directions with respect to the inner case 20. During such rotation, a force around the rotation axis A1 is applied from the outer case 30 to the inner case 20, particularly to the front member 21 including the first side surface portion 212, due to friction with the outer case 30. The above rotation restricting portion prevents the front side member 21 and the back side member 22 included in the inner case 20 from relatively rotating due to such a force. The open and closed states of the vent holes 23 and 24 of the inner case 20 are formed according to the relative rotational positions of the inner case 20 and the outer case 30, but the front side member 21 is temporarily attached to the outer case 30. If the back side member 22 is rotated with respect to the back side member 22, it becomes impossible to appropriately switch the opening and closing of the vent holes 23 and 24. However, in this case, since the relative rotation of the front side member 21 and the back side member 22 is regulated by the above-described rotation regulation portion, such a situation is prevented. Further, as will be described later in detail, the back sheet 12 of the container 10 which is non-rotatably fixed to the front side member 21 is punctured by the pressing portion 417 of the fixture 40 which is non-rotatably fixed to the back side member 22 and broken. Get burned. Then, as a result, holes are formed in the back sheet 12 for allowing the medicine to exude from the inside of the container 10. Therefore, if the front side member 21 rotates with respect to the back side member 22, the pressing portion 417 moves on the back sheet 12, and the back sheet 12 is excessively torn. Then, the medicine leaks more than necessary through the back sheet 12. However, here, such a situation is prevented because the rotation restricting portion restricts the relative rotation between the front member 21 and the rear member 22.

However, the circumferential distance between the protrusions 216 and 217 is larger than the circumferential width of the claw portion 224. That is, the rotation restricting portion configured by the protrusions 216 and 217 and the claw portion 224 has a play around the rotation axis A1, and allows the front side member 21 to rotate by a predetermined amount with respect to the back side member 22. This is because if the front side member 21 and the rear side member 22 are relatively unrotatable, the force around the rotation axis A1 applied by friction from the outer case 30 to the inner case 20 loses its escape area. .. In that case, the inner case 20 tries to rotate due to the rotation of the outer case 30, and the fixture 40 fixed to the inner case 20 so as not to rotate also tries to rotate similarly. In this case, the part to which the fixture 40 is attached, typically, the louver at the air outlet of the air conditioner, may be damaged. However, here, since the relative play between the front side member 21 and the back side member 22 is allowed to some extent by the play of the rotation restricting portion described above, such a situation is prevented. Further, this play can also function as a clearance that can eliminate a defect when the inner case 20 and the outer case 30 are assembled.

The first back surface 221 is formed with a first introduction port 23 for introducing the air blown from the air outlet of the air conditioner into the inner case 20. On the other hand, the first front surface portion 211 is formed with a first discharge port 24 for discharging the air introduced into the inner case 20 through the first introduction port 23 to the outside. In the present embodiment, the first introduction port 23 includes a plurality of (more specifically, three) communication ports 23a to 23c, and the first discharge port 24 also includes a plurality of (more specifically, three) communication ports 23a to 23c. ) Including communication ports 24a to 24c. The communication ports 23a to 23c are arranged in the outer peripheral direction of the first back surface part 221, and the communication ports 24a to 24c are also arranged in the outer peripheral direction of the first front surface part 211. The communication ports 23a to 23c are arranged at equal intervals around the rotation axis A1. The communication ports 24a to 24c are also arranged at equal intervals around the rotation axis A1.

In the present embodiment, the communication ports 23a to 23c are arranged so as to overlap the communication ports 24a to 24c in a front view. As a result, the air blown out from the air outlet of the air conditioner appropriately and efficiently passes through the inside of the inner case 20 from the rear to the front while appropriately volatilizing the medicine that has exuded from the holes formed in the back sheet 12. be able to. In addition, in this embodiment, the communication ports 23a to 23c and the communication ports 24a to 24c have substantially the same shape, and they overlap with each other in the front view with almost no displacement. Further, the above-described rotation restricting portion has a positioning function for surely facing the communication ports 23a to 23c and the communication ports 24a to 24c when the front member 21 and the rear member 22 are connected to each other in a front view. Also has.

A sign area 25 is arranged on the front surface (outer surface) of the first front surface portion 211 at a position between the communication ports 23a to 23c along the circumferential direction. The signature area 25 is an area in which a signature such as a character or a graphic is written, and in the example of FIG. 7, the character “OFF” is written. Although the details will be described later, the sign in the sign area 25 is a sign indicating that the vent holes 23 and 24 of the inner case 20 that houses the container 10 are closed.

An opening 221a penetrating in the front-rear direction is formed near the center of the first back surface portion 221. The opening 221a has a square shape that is concentric with the outer peripheral edge of the first back surface portion 221 in a front view. Although details will be described later, the base portion 41 of the fixture 40 is inserted into the opening 221a. A protrusion 225 is formed on the front surface of the first back surface 221 at a position facing the center of each side of the opening 221a. When the inner case 20 is closed so as to hold the container 10 inside, each of the protrusions 225 comes into contact with the overlapping portion of the flange portion 112 of the container 10 and the back sheet 12, and supports this from the back side.

When the container 10 is held in the inner case 20, the front surface (inner surface) of the first back surface 221 faces the back sheet 12 of the container 10. FIG. 10 is a front view of the back side member 22. Although omitted in FIG. 7, the inner surface of the first back surface portion 221 facing the back sheet 12 has an uneven region C1 as shown in FIG. In the concavo-convex region C1, a large number of microspaces for holding the liquid component of the drug exuded from the back sheet 12 are formed. In the present embodiment, a large number of ribs 226 extending substantially parallel to each other are formed in the concavo-convex region C1, and the gap between the ribs 226 forms a channel-shaped fine space. When the liquid component of the medicine leaked from the back sheet 12 is attached on the first back surface 221, it is captured by the capillary phenomenon so as to be sucked into such a minute space. Therefore, even when the drug leaking from the back sheet 12 is difficult to volatilize, especially when the drug volatilizer 1 is not used, the liquid component of the drug leaks from the drug volatilizer 1 and stains the surroundings. The situation is suppressed.

As shown in FIG. 10, on the front surface (inner surface) of the first rear surface portion 221, in addition to the rib 226, an enclosure wall 227 arranged to surround the communication ports 23a to 23c and an opening 221a near the center. A surrounding wall 228 is provided so as to surround it. The enclosing wall 227 plays a role of preventing the liquid component of the medicine adhering to the first back surface part 221 from leaking to the outside through the communication ports 23a to 23c. On the other hand, in the surrounding wall 228, the liquid component of the drug adhering to the first back surface part 221 is exposed to the outside through the gap formed between the fixture 40 inserted into the opening 221a and the first back surface part 221. It serves to prevent leakage.

As shown in FIG. 9, a ring-shaped projecting wall 229 extending to the back side stands up on the back side surface (outer surface) of the first back surface portion 221. The projecting wall 229 is arranged so as to surround the opening 221a, and has a circular shape that circumscribes the four corners of the square opening 221a in a rear view. As will be described later in detail, the protruding wall 229 has a function of receiving the flange portion 413 of the fixture 40 in the inner space thereof and preventing the liquid component of the medicine from leaking out through the opening 221a.

<2-3. Fixture>
FIG. 11 shows a perspective view of the fixture 40 viewed from the front side, and FIG. 12 shows a side view thereof. Although not limited to this, the fixture 40 is made of a resin such as polypropylene or polyacetal. The fixture 40 has a base portion 41 and a clip portion 42 extending rearward from the base portion 41 and fixed to the vicinity of the air outlet of the air conditioner, typically, a louver. In the present embodiment, the fixture 40 is integrally formed as one component so that the whole is inseparable.

The base portion 41 has a tubular body portion 411, a bottom surface portion 412 arranged so as to close an opening on the back side of the body portion 411, and a flange portion 413. The flange portion 413 extends radially outward from the outer peripheral surface of the body portion 411 along the circumferential direction. The outer peripheral edges of the body portion 411 and the bottom surface portion 412 are square in a front view, and have a shape that substantially matches the opening 221a of the first back surface portion 221. On the other hand, the outer peripheral edge of the flange portion 413 has a circular shape that circumscribes the four corners of the square body portion 411 in a front view. As a result, the body portion 411 is inserted into the opening 221a of the first back surface portion 221 from the back surface side, but cannot pass through because of the flange portion 413. When the fixture 40 is fixed to the back surface side member 22, the flange portion 413 is connected to a portion of the body portion 411 that protrudes from the opening 221a toward the back surface in the front-rear direction.

The body portion 411 has a pair of notches 414 and 414 near the center of two sides facing each other in a front view. A thin plate-shaped elastic piece 415 extending in the front-rear direction is provided between each pair of cuts 414 and 414. Each elastic piece 415 is provided with a protrusion 416 extending outward in the radial direction of the body 411. When the body 411 is inserted into the opening 221a from the rear side to connect the fixture 40 and the first rear surface 221, the protrusion 416 is pushed by the outer peripheral portion 230, and the elastic piece 415 is inclined inward. Elastically deforms. The outer peripheral portion 230 is a part of the first back surface portion 221, and is a portion surrounding the opening 221a in the vicinity of the opening 221a so as to define the opening 221a. Due to the elastic deformation of the elastic piece 415 as described above, the protrusion 416 passes through the opening 221a, and after the passage, the elastic piece 415 returns to the original position, and the protrusion 416 surrounds the opening 221a. Side surface). As a result, unless a strong external force is applied, the connection state between the fixture 40 and the first back surface portion 221 is maintained, and the fixture 40 is unintentionally removed from the inner case 20 due to an unexpected hand contact, vibration of the vehicle, or the like. It is prevented from falling off. The fixture 40 is attached to the inner case 20 so as to extend rearward from the first back surface portion 221.

A pressing portion 417 is provided at the front end of the body portion 411 in the vicinity of the four corners as viewed from the front. The pressing portion 417 is a protrusion whose front side is sharpened. The pressing portion 417 presses the back sheet 12 of the container 10 to break through when the inner case 20 is closed so as to hold the container 10 inside. As a result, the fracture layer 122 included in the back sheet 12 is fractured. On the other hand, the volatilization layer 121 does not break due to its high extensibility, but since it is composed of a porous film, it can allow the drug to permeate. Therefore, after being pressed by the pressing portion 417, the backsheet 12 has a hole through which the medicine exudes. Then, the drug exudes from the inside of the container 10 to the space on the back surface side of the back sheet 12 through these holes. The exuded medicine is highly densely accumulated in the space formed between the back sheet 12 and the first back portion 221, and is carried to the outside by riding on the air flow passing through the space.

FIG. 13 is a cross-sectional view showing a structure of a connecting portion between the fixture 40 and the outer peripheral portion 230 surrounding the opening 221a in the first back surface portion 221. As shown in the figure, the outer peripheral portion 230 has a base surface 231 facing the flange portion 413 of the base portion 41 and spaced from the flange portion 413. The base surface 231 is a surface that spreads so as to face the back surface side in a plane orthogonal to the front-rear direction. Further, the outer peripheral portion 230 is provided with a protruding portion 232 that protrudes from the base surface 231 to the rear surface side so as to contact the flange portion 413. As shown in FIG. 9, the projecting portion 232 is arranged in four parts in a portion surrounded by the projecting wall 229 on the base surface 231. Both ends of each of the four protrusions 232 are continuous with the protrusion wall 229 in a rear view. On the other hand, the flange portion 413 has a base surface 418 facing the inner peripheral surface of the protruding wall 229 included in the outer peripheral portion 230 and spaced from the inner peripheral surface of the protruding wall 229. The base surface 418 is a side peripheral surface that extends in the thickness direction of the flange portion 413. Further, as shown in FIG. 13, the flange portion 413 is provided with a protruding portion 419 that protrudes radially outward so as to contact the inner peripheral surface of the protruding wall 229 from the base surface 418. Although not shown in FIGS. 11 and 12, the protrusion 419 extends over the entire circumference of the flange 413 in the circumferential direction.

Since the contact portion between the protrusion 232 and the flange portion 413 is located on the route from the inside of the first back surface portion 221 to the outside through the opening 221a (hereinafter referred to as the leakage route), the leakage route should be closed. You can Therefore, the contact portion forms a breakwater for the liquid component of the medicine, and it is possible to prevent the medicine from leaking from the inner case 20 through the leakage route. Further, as shown in FIG. 9, the protruding portion 232 has a rib shape and extends in an elongated shape. As a result, the contact area between the protruding portion 232 and the flange portion 413 is narrowed, and the effect of preventing the leakage of the drug is enhanced. That is, it is assumed that the protrusion 232 is omitted and the entire base surface 231 makes surface contact with the flange portion 413. In this case, a gap between these contact surfaces is formed long on the leak route along the extending direction of the leak route. Then, due to the capillary phenomenon, the liquid component contained in the drug is easily sucked out through the narrow gap between the contact surfaces. In this regard, here, since the protruding portion 232, which occupies a short width along the direction in which the leakage route extends from the base surface 231, only contacts the flange portion 413, it is difficult for the drug to be sucked out by such a capillary phenomenon. Has become.

Similarly, since the contact portion between the protruding portion 419 and the protruding wall 229 is also located on the leak route, the leak route can be closed. Therefore, this contact portion also forms a breakwater for the liquid component of the drug, and can prevent the drug from leaking from the inner case 20 through the leak route. The protruding portion 419 also has a rib shape and extends in a slender shape. As a result, the contact area between the protruding portion 419 and the protruding wall 229 is narrowed, and the effect of preventing the leakage of the medicine is enhanced. That is, if the protruding portion 419 is omitted and the entire base surface 418 is in surface contact with the protruding wall 229, a gap between these contact surfaces is formed long on the leak route along the direction in which the leak route extends. As a result, the liquid component contained in the drug is easily sucked out to the outside. In this respect, here, since the protruding portion 419 that occupies a short width along the direction in which the leakage route extends from the base surface 418 only contacts the protruding wall 229, it is difficult for the drug to be sucked out by such a capillary phenomenon. Is becoming

Further, the base surfaces 231 and 418 on which the plurality of protrusions 232 and 419 stand, respectively, are arranged so as to form an angle with each other, and particularly to be substantially orthogonal to each other in the present embodiment. That is, the contact portion between the protruding portion 232 and the flange portion 413 and the contact portion between the protruding portion 419 and the protruding wall 229 are separately arranged on the route before and after the leakage route is bent. Thereby, leakage of the medicine from the inner case 20 is further suppressed.

The clip portion 42 has a pair of protruding pieces 421 and 422. The projecting pieces 421 and 422 face each other and extend rearward from the back surface of the base portion 41 (back surface of the bottom surface portion 412). The projecting pieces 421 and 422 can be bent by a predetermined amount by elastic deformation so as to be further apart from each other with reference to the base portion on the base portion 41 side. Therefore, by applying an external force to the projecting pieces 421 and 422, the interval between the projecting pieces 421 and 422 can be widened. By sandwiching the louver of the air conditioner in the gap between the projecting pieces 421 and 422 thus widened, the position of the clip portion 42 and thus the entire drug volatilizer 1 can be fixed.

<2-4. Outer case>
FIG. 14 shows an exploded perspective view of the outer case 30. As shown in the figure, the outer case 30 has a front-side member 31 and a back-side member 32 that are removable in the front and rear. FIG. 15 is a perspective view of the front side member 31 as viewed from the back side. Although not limited to this, the outer case 30 is made of resin such as polypropylene. In the present embodiment, the front side member 31 is integrally configured as one component in an inseparable manner, and the back side member 32 is also integrally configured as a single component in an entirely inseparable manner. ing.

The front side member 31 has a second front surface section 311 and a cylindrical second side surface section 312 extending from the outer peripheral edge of the second front surface section 311 to the rear surface side. On the other hand, the rear surface member 32 has a second rear surface portion 321 that is detachably connected to the rear surface side end portion of the second side surface portion 312. The second side surface portion 312 connects the second front surface portion 311 and the second rear surface portion 321 in the front-rear direction.

The outer peripheral edge of the second front face 311 is circular when viewed from the front, and an opening 311a penetrating in the front-rear direction is formed near the center. The opening 311a also has a circular shape that is concentric with the outer peripheral edge of the second front surface portion 311 when viewed from the front. A cylindrical inner wall portion 313 standing upright toward the back surface is continuous with the second front surface portion 311 along the outer peripheral edge of the opening 311a. The inner wall portion 313 is inserted into a gap formed between the inner wall portion 213 of the inner case 20 and the cup portion 111 of the container 10 inserted therein. As a result, the outer peripheral surface of the inner wall portion 313 of the outer case 30 faces the inner peripheral surface of the inner wall portion 213 of the inner case 20 with a gap. The upper part of the cup part 111 of the container 10 is inserted into the space inside the inner wall part 313 from the back side. In the state where the inner case 20 and the outer case 30 are connected, the central axes of both are coincident with the rotation axis A1.

On the inner wall portion 313 of the outer case 30, a plurality of slits 314 cut from the back side are formed. The plurality of slits 314 are arranged at equal intervals around the rotation axis A1. In this embodiment, the six slits 314 are arranged at 60° intervals. On the other hand, returning to FIG. 7, the inner wall portion 213 of the inner case 20 is provided with a thin plate-shaped elastic piece 250 extending along the circumferential direction inside one of the four diameter-enlarged portions 213a. .. A protrusion 251 extending inward in the radial direction is provided at the tip of the elastic piece 250. The protrusion 251 is configured to be sequentially hooked and locked by the plurality of slits 314 as the outer case 30 rotates about the rotation axis A1 relative to the inner case 20. That is, the protrusion 251 applies a force to the inner wall portion 313 to resist the force in the rotation direction applied to the outer case 30 in the locked state in which the protrusion 251 is hooked on any of the slits 314. However, when a force in the rotation direction of a certain amount or more is applied to the outer case 30, the elastic piece 250 bends by the elastic deformation so as to warp outward in the radial direction, and the projection 251 falls off from the slit 314. As a result, the resistance force is weakened and the outer case 30 rotates. When the outer case 30 rotates and the protrusion 251 reaches the position of the next slit 314, the protrusion 251 is fitted into the next slit 314 again. As a result, the locked state is formed again.

The locked state is formed every time the outer case 30 rotates by an angle (60° in the present embodiment) corresponding to the circumferential arrangement interval of the slits 314. Further, every time the locked state is formed, a closed position where the first introduction port 23 and the first discharge port 24 of the inner case 20 are closed and an open position where they are opened appear alternately. The protrusion 251 is locked in one of the plurality of slits 314 when the outer case 30 is in the closed position, and is locked in another one of the plurality of slits 314 when the outer case 30 is in the open position. To be done. Therefore, the switching between the open position and the closed position can be easily understood by the user. Further, since it is firmly locked, it is possible to prevent the open position and the closed position from being switched unintentionally when a force is applied due to an unexpected hand contact or a vibration of the vehicle. Therefore, the outer case 30 can be easily and reliably set in the closed position and the open position. Therefore, the user can easily control the opening amount of the vent holes 23 and 24 formed in the inner case 20. In the present embodiment, the open position and the open position appear multiple times, more specifically, three times while the outer case 30 makes one rotation with respect to the inner case 20. To enable this, the slits 314 are arranged in a number equal to the sum of the number of closed positions existing around the rotation axis A1 and the number of open positions.

The outer peripheral edge of the second back surface portion 321 is a circular plate member, and the outer peripheral edge substantially coincides with the second front surface portion 311 in a front view. As shown in FIG. 14, on the outer peripheral edge of the second back surface portion 321, a plurality of projecting portions 322 that slightly project radially outward are arranged at predetermined intervals along the circumferential direction. In the present embodiment, the protrusions 322 are spaced by 60° along the circumferential direction and extend by 60°. On the other hand, as shown in FIG. 15, a plurality of projecting portions 317 that slightly project to the rear surface side are arranged at the rear surface side end portion of the second side surface portion 312 at predetermined intervals along the circumferential direction. ing. In the present embodiment, the protrusions 317 are spaced at intervals of 60° along the circumferential direction and extend by 60°. As shown in FIG. 2, the plurality of protrusions 317 are respectively received in the circumferential gaps between the plurality of protrusions 322, and conversely, the plurality of protrusions 322 are arranged in the circumferential direction between the plurality of protrusions 317. It is received in each gap.

The protrusions 317 and the protrusions 322 are arranged in a staggered manner in the circumferential direction, so that the front-side member 31 regulates rotation of the front-side member 31 relative to the rear-side member 32 around the rotation axis A1. Function as. When the protrusions 317 are fitted in the gaps between the protrusions 322, they are surrounded by the protrusions 322 from both sides around the rotation axis A1. Similarly, when the protrusions 322 are fitted in the gaps between the protrusions 317, they are surrounded by the protrusions 317 from both sides around the rotation axis A1. Therefore, the protrusion 317 and the protrusion 322 can restrict mutual rotation in the forward direction and the reverse direction around the rotation axis A1. In other words, the rotation restricting portion described above restricts the relative rotation of the front side member 21 with respect to the back side member 22 in the forward direction and the reverse direction.

Although omitted in the drawings so far, as shown in FIG. 16, the protrusion 317 is provided with a protrusion 318 that protrudes inward in the radial direction. On the other hand, in the outer peripheral portion of the second back surface portion 321, a protrusion 323 that protrudes radially outward is provided in a gap portion between the plurality of protruding portions 322. When the front side member 31 and the back side member 32 are connected to each other, due to elastic deformation of these, the protrusion 318 and the protrusion 323 pass over each other, and the protrusion 318 and the protrusion 323 are caught by each other. As a result, unless a strong external force is applied, the front side member 31 and the rear side member 32 are maintained in a connected state, and the both members 31 and 32 are unintentionally disengaged due to a sudden hand contact, vibration of the vehicle, or the like. There is no.

An opening 321a penetrating in the front-rear direction is formed near the center of the second back surface 321. The opening 321a has a circular shape that is concentric with the outer peripheral edge of the second back surface portion 321 in a front view. As shown in FIG. 2, the protruding wall 229 of the first rear surface portion 221 of the inner case 20 with the flange portion 413 of the fixture 40 inserted therein is inserted into the opening 321a. As shown in FIG. 9, the protruding wall 229 is formed with a plurality of protrusions 240 that extend radially outward and are arranged at intervals in the circumferential direction. At the time of connecting the outer case 30 and the inner case 20, the second back surface part 321 is placed on the back surface side of the first back surface part 221 while the fixture 40 projecting from the first back surface part 221 of the inner case 20 is passed through the opening 321a. Close to cover. At this time, due to the elastic deformation of the protruding wall 229, the protrusion 240, and the second back surface portion 321, the projection 240 rides over the portion of the second back surface portion 321 surrounding the opening 321a, and the two are caught in the front-rear direction. As a result, unless a strong external force is applied, the second back surface part 321 is prevented from falling off from the first back surface part 221 to the back surface side, and these members 321 and 221 are prevented from coming into contact with the hands or vibration of the vehicle. Does not come off unintentionally. On the other hand, the protrusion 240 does not prevent the rotation of the second back surface portion 321 around the rotation axis A1. Therefore, the second back surface part 321 of the outer case 30 can freely rotate around the rotation axis A1 with respect to the first back surface part 221 of the inner case 20.

Air vents 33 and 34 are formed in the outer case 30. More specifically, the second rear surface 321 is formed with a second introduction port 33 for introducing the air blown out from the air outlet of the air conditioner into the outer case 30. On the other hand, the second front face 311 is formed with a second discharge port 34 for discharging the air introduced into the outer case 30 through the second introduction port 33 to the outside. In the present embodiment, the second introduction port 33 includes a plurality of (more specifically, three) communication ports 33a to 33c, and the second discharge port 34 also includes a plurality of (more specifically, three) communication ports 33a to 33c. ) Including communication ports 34a to 34c. The communication ports 33a to 33c are arranged in the outer peripheral direction of the second back surface part 321, and the communication ports 34a to 34c are also arranged in the outer peripheral direction of the second front surface part 311. The communication ports 33a to 33c are arranged at equal intervals around the rotation axis A1. The communication ports 34a to 34c are also arranged at equal intervals around the rotation axis A1.

In the present embodiment, the communication ports 33a to 33c are arranged so as to overlap the communication ports 34a to 34c in a front view. In the present embodiment, the communication ports 33a to 33c and the communication ports 34a to 34c have substantially the same shape, and overlap with each other in the front view with almost no displacement. The rotation restricting portion of the outer case 30 described above is positioned to ensure that the communication openings 33a to 33c and the communication openings 34a to 34c face each other when the front side member 31 and the back side member 32 are connected to each other in a front view. It also has the function of.

When the outer case 30 is in the open position, the communication ports 33a to 33c that are the second introduction ports 33 overlap the communication ports 23a to 23c that are the first introduction ports 23 of the inner case 20 in a front view. Further, at this time, the communication ports 34a to 34c that are the second discharge ports 34 respectively overlap the communication ports 24a to 24c that are the first discharge ports 24 of the inner case 20 in a front view. In addition, in this embodiment, the communication ports 23a to 23c and 24a to 24c of the inner case 20 and the communication ports 33a to 33c and 34a to 34c of the outer case 30 have substantially the same shape, and When the case 30 is in the open position, they overlap with each other in front view with almost no displacement.

On the other hand, when the outer case 30 is in the closed position, the communication ports 33a to 33c that are the second introduction ports 33 do not overlap the communication ports 23a to 23c that are the first introduction ports 23 in a front view. In addition, at this time, the communication ports 34a to 34c that are the second discharge ports 34 do not overlap the communication ports 24a to 24c that are the first discharge ports 24, respectively, in the front view, and respectively overlap the above-described sign area 25. Therefore, the signature of the signature area 25 can be visually recognized from the outside of the medicine volatilizer 1 through the communication ports 34a to 34 functioning as windows.

In other words, when the outer case 30 is in the closed position, the second back surface portion 321 of the outer case 30 covers all the communication ports 23a to 23c that are the first introduction ports 23 of the inner case 20 from the outside and closes them. Further, at this time, the second front face 311 of the outer case 30 covers all the communication ports 24a to 24c, which are the first discharge ports 24 of the inner case 20, from the outside and closes them. On the other hand, when the outer case 30 is in the open position, the second back surface portion 321 of the outer case 30 opens all the communication ports 23a to 23c that are the first introduction ports 23 of the inner case 20. Further, at this time, the second front surface portion 311 of the outer case 30 opens all the communication ports 24a to 24c which are the first discharge ports 24 of the inner case 20.

As described above, when the outer case 30 is in the open position, the communication ports 23a to 23c and 24a to 24c of the inner case 20 and the communication ports 33a to 33c and 34a to 34c of the outer case 30 are circumferentially equidistant. They are arranged separately on three straight lines extending in the front-rear direction. As a result, the air blown out from the air outlet of the air conditioner volatilizes the medicine that has exuded through the holes formed in the back sheet 12, while the inside of the inner case 20 and the outer case 30 accommodating the inner case 20 are housed from the rear to the front. It can pass to and appropriately. Therefore, the drug volatilizer 1 can appropriately volatilize the drug. On the other hand, when the outer case 30 is in the closed position, the communication holes 23a to 23c and 24a to 24c of the inner case 20 are all closed by the outer case 30, so that the medicine is trapped in the inner case 20 and the medicine is wasted. Volatilization is prevented.

As described above, the outer case 30 is switched between the closed position and the open position by rotating around the rotation axis A1 with respect to the inner case 20. At this time, the outer case 30 can rotate 360° with respect to the inner case 20 around the rotation axis A1. Further, the outer case 30 can rotate with respect to the inner case 20 around the rotation axis A1 in both the forward and reverse directions. Therefore, regardless of whether the chemical volatilizer 1 is installed on the left side or the right side of the user, whether the user is right-handed or left-handed, the user freely rotates the outer case 30, It is possible to easily open and close the inner case 20.

<3. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the following changes are possible. Further, the gist of the following modified examples can be appropriately combined.

Configured to open all of. However, the outer case 30 in the open position opens only a part of the communication ports 24a to 24c of the first discharge port 24 of the inner case 20, and only a part of the communication ports 23a to 23c of the first introduction port 23. It may be configured to open. For example, in the outer case 30, this is realized by omitting a part of the communication ports 33a to 33c that are the second introduction ports 33 and omitting a part of the communication ports 34a to 34c that are the second discharge ports 34. can do.

In the above-described embodiment, the claw portion 224 is formed on the back side member 22 of the inner case 20, and the accommodation portion into which the claw portion 224 is inserted is formed on the front side member 21. However, conversely, the front side member 21 may be formed with the claw portion and the rear side member 22 may be formed with the accommodating portion. The rotation restricting portion that restricts the rotation of the front side member 21 with respect to the back side member 22 is not limited to the configuration including the claw portion and the accommodating portion as described above, and may include elements that are caught by each other in the rotation direction around the rotation axis A1. Various configurations that have can be adopted. Further, the position where the rotation restricting portion that restricts the rotation of the front side member 21 with respect to the rear side member 22 is formed is not limited to that described above. For example, when the rear surface side member 22 has a side surface portion that extends forward from the outer peripheral portion of the first rear surface portion 221, in addition to the first rear surface portion 221, the accommodation portion is formed on the inner peripheral surface of the rear surface portion, and the accommodation portion is formed. The claw portion that is fitted into the front side may be formed in the front side member 21.

In the above-described embodiment, a large number of ribs (projections) 226 extending substantially parallel to each other are formed in the uneven region C1. However, the concavo-convex region C1 can be changed to various structures as long as a fine space suitable for holding the liquid component of the drug is formed. For example, in addition to the ribs 226 described above, a large number of ribs (projections) 237 intersecting (preferably orthogonal to) the ribs 226 may be further formed in the uneven region C1 (see FIG. 17A). In this case, the ribs 226 and 237 spread out in a grid pattern, and a large number of square-shaped fine spaces surrounded by the ribs 226 and 237 are formed. Further, instead of or in addition to the rib 226, a large number of grooves (recesses) may be formed. Similarly, in place of or in addition to the rib 237, a large number of grooves (recesses) may be formed. Further, instead of forming the convex portions in a linear shape like the ribs 226 and 237, the convex portions 238 may be arranged in a dot shape as shown in FIG. 17B, for example. Similarly, instead of the linear groove (recess), the recess may be arranged in a dot shape. Also in these examples, a fine space capable of holding the liquid component of the drug is formed.

<3-5>
In the above-described embodiment, the clip 40 is provided on the fixture 40, and the chemical volatilizer 1 can be clipped to a louver or the like. However, the method for installing the chemical volatilizer 1 is not limited to this, and may be fixed to the louver or the like by a double-sided seal or the like.
