It is locked to the stepped portion between the small diameter portion 111a and the large diameter portion 111b. This makes it difficult for the case cover 150 to come off from the case 210 .

(Perfume holder)
Liquid perfumes are held in the perfume holders 251a and 251b arranged in the holding spaces 231a and 231b, respectively. For example, the perfume carrier 251 may be an impregnating material that can be impregnated with a liquid perfume. The impregnating material is preferably a porous body or a fibrous body in order to increase the retention efficiency (impregnability) of the liquid perfume. Also, the impregnating material is preferably a material that is resistant to liquid perfumes. For example, the impregnating material may be synthetic fiber bundles or felt made of polyester, nylon, acrylic, polyacetal, or the like.

In the perfume cartridge 200 according to the present embodiment, the perfume holder 251 is formed of a synthetic fiber bundle obtained by forming fibers made of polyester resin into a sheet shape. is bent to fit in the holding space 231 . When the fiber density of the flavorant carrier 251 is increased in order to enhance the impregnating property of the liquid flavorant, the flexural rigidity of the flavorant carrier 251 is increased. For this reason, the fragrance holder 251 is provided with a fragile portion so that the fragrance holder 251 can be easily bent.

FIG. 17 is an explanatory diagram showing a state in which perfume holders 251a and 251b are arranged in respective holding spaces 231a and 231b of first case body 211 shown in FIG. The perfume holders 251a and 251b are arranged in holding spaces 231a and 231b having curved cross-sectional shapes, respectively. When the first case body 211 is viewed in the axial direction, the perfume holders 251a and 251b are arranged so as not to overlap the first openings 221a and 221b. Movement of the perfume holders 251a, 251b toward the first openings 221a, 221b is restricted by first ribs 235a, 235b formed on the inner peripheral surfaces of the holding spaces 231a, 231b. The first ribs 235a, 235b function as restricting portions. A space in which the first openings 221a and 221b are located functions as a ventilation area A through which air flows.

18 is a perspective view showing the perfume holder 251 arranged in the holding space 231. FIG. The perfume holder 251 has fragile portions 254 a and 254 b formed along the axial direction of the first case body 211 . The fragile portions 254a and 254b of the flavorant holder 251 provided in the flavorant cartridge 200 according to the present embodiment are formed by cutting lines provided on one surface of the sheet-like flavorant holder 251 . The fragile portions 254a and 254b are provided on a line along a predetermined direction that intersects the bending direction in which the flavor holder 251 is bent. That is, the fragile portions 254a and 254b are provided along the direction in which the center line of the holding space 231, which has a ring-shaped cross section as a whole, extends. Therefore, even if the sheet-like flavor holder 251 has relatively high bending rigidity, it can be easily bent according to the shape of the holding space 231 . Therefore, the perfume holder 251 is easily accommodated even in the holding space 231 having a curved cross-sectional shape.

The perfume holder 251 has a first portion 252a, a second portion 252b and a third portion 252c separated by two fragile portions 254a and 254b. Of these, the first portion 252a is arranged adjacent to the ventilation area A where the first opening 221 is located. The first portion 252a has a weir portion 253 that protrudes beyond the end positions of the second portion 252b and the third portion 252c. As will be described later, the weir 253 has a function of preventing the liquid flavor from entering the ventilation area A when the liquid flavor is injected into the holding space 231 .

The fragile portions 254a and 254b shown in FIG. 18 are provided so as to be positioned on the outer peripheral surface when the flavor holder 251 is bent. may be provided to do so. However, when the fragile portion 254 is formed by the cutting line, the fragile portions 254a and 254b are provided so as to be located on the outer peripheral surface when the flavor holder 251 is bent, in order to make the flavor holder 251 more bendable. preferably.

Also, the number of fragile portions 254 is not limited to two. The shorter the interval between the fragile portions 254 arranged along the bending direction of the flavoring material holder 251, the easier the flavoring material holder 251 bends. As shown in FIGS. 19 and 20, the shorter the interval between the fragile portions 274 arranged along the bending direction of the perfume holder 251, the easier the perfume holder 251 bends and the smoother the curved surface of the perfume holder 251. can be shaped.

Also, the fragile portion 254 is not limited to the fragile portion 254 formed of a cutting line that continues along one direction. For example, as shown in FIGS. 21 and 22, the fragile portion 284 may be formed by a concave groove provided on one side surface of the sheet-like flavor holder 281 . Alternatively, as shown in FIGS. 23 and 24, a fragile portion 294 may be formed by intermittently providing a cutting line passing through a sheet-like flavor holder 291 along one direction. That is, the fragile portion 294 may be formed by perforations. Further, the fragile portion may be formed by a hole penetrating through the sheet-like flavor holder. The cutting lines or grooves formed on one side surface of the flavorant carrier, or the cutting lines or holes formed through the flavorant carrier are continuous or intermittent unless the flavorant carrier is completely divided. can be formed systematically.

(Action of Perfume Cartridge)
The action of the perfume cartridge 200 according to this embodiment will be described.

FIG. 25 is a schematic diagram showing how the perfume holder 251 is accommodated in the holding space 231. As shown in FIG. Each holding space 231 includes a ventilation area A, as described above. The ventilation region A is a region in which both ends in the axial direction face the first opening 221 and the communication hole 101 . In this embodiment, the ventilation area A of each holding space 231 communicates with the second opening 151 of the case cover 150 via the communication hole 101 of the second case body 100 . The ventilation region A linearly connects the first opening 221, the communication hole 101, and the second opening 151 along the axial direction. Therefore, the ventilation resistance of the air supplied from the first opening 221 into the holding space 231 and flowing through the communication hole 101 to the second opening 151 is reduced.

The perfume holder 251 is arranged adjacent to the ventilation area A in a direction intersecting with the axial direction. Therefore, the liquid perfume held in the perfume holder 251 is vaporized by the flow of air passing through the ventilation region A. As shown in FIG. If the perfume holder 251 is in a form in which the impregnating material is impregnated with the liquid perfume, the liquid perfume permeates the portion of the impregnating material located on the ventilation region A side, so that the perfume is continuously vaporized. be done.

Movement of the perfume holder 251 toward the ventilation area A is restricted by the first rib 235 . Therefore, the ventilation resistance of the air passing through the ventilation area A is less likely to increase. In addition, since the space from the first opening 221, which is the air supply port, to the communication hole 101 leading to the second opening 151, which is the air discharge port, is a closed space without other openings, All the vaporized perfume can be efficiently discharged from the discharge port.

The dimension of the first portion 252a in the longitudinal direction (the axial direction of the perfume cartridge 200) may substantially match the axial length of the holding space 231, for example. On the other hand, the longitudinal dimension of the second portion 252b and the third portion 252c is the same as that of the second rib of the second case body 100 when the second case body 100 is assembled to the first case body 211. 121 and the bottom surface of the holding space 231 of the first case body 211 . As a result, displacement of the perfume holder 251 within the holding space 231 is suppressed. Further, when the direction of the perfume holder 251 to be inserted into the holding space 231 is reversed, the second case body 100 may be inserted before the second case body 100 is correctly mounted on the first case body 211. Since the second rib 121 of 100 abuts against the flavor holder 251, misinsertion of the flavor holder 251 can be prevented.

The flavoring inlet 105 of the second case body 100 is positioned closer to the second portion 252b than the weir portion 253 provided in the first portion 252a of the flavoring holder 251 . Since the dam 253 of the first portion 252a is arranged between the flavoring inlet 105 and the ventilation area A, the liquid flavoring to be injected flows along the tip surface of the flavoring holder 251 toward the third portion 252c. It permeates into the perfume holder 251 while flowing. As a result, the liquid flavoring agent is suppressed from entering the ventilation area A, and leakage of the liquid flavoring agent from the first opening 221 and the communication hole 101 can be prevented.

FIG. 26 is an explanatory diagram showing how liquid perfume is injected into the perfume cartridge 200. As shown in FIG. The user can inject any liquid fragrance into the holding space 231 using the injection jig 300 before attaching the case cover 150 to the case 210 . Specifically, the user inserts the tip of the injection jig 300 into the flavoring inlet 105 of the second case body 100 to inject the liquid flavoring into the holding space 231 . Thereby, the liquid perfume can be held in the perfume holder 251 arranged in the holding space 231 . The injection jig 300 may be any device whose tip can be inserted into the fragrance injection port 105, and may be, for example, a syringe, a pipette, a dropper, or the like.

The second case body 100 is provided with displays 131a and 131b for making it easy to determine which holding spaces 231a and 231b correspond to the two perfume inlets 105a and 105b. Therefore, it is possible to prevent the user from accidentally injecting the liquid perfume into the different holding space 231 .

Further, ribs 115a and 115b are provided inside the communication holes 101a and 101b that serve as ventilation holes. Therefore, it is possible to prevent the user from inserting the injection jig 300 into the communication holes 101a and 101b by mistake. As a result, it is possible to prevent the liquid perfume from entering the ventilation area A and leaking out from the first opening 221 or the second opening 151 .

After injecting the liquid flavoring into the holding space 231, the flavoring inlet 105 may be sealed to prevent leakage of the liquid flavoring from the flavoring inlet 105. FIG. FIG. 27 is a perspective view showing an example of a sealing jig 320 for closing the flavoring inlet 105, and FIG. 28 is an explanatory diagram showing a state in which the flavoring inlet 105 is sealed.

A sealing jig 320 shown in FIG. 27 includes a sealing portion 321 and a support portion 323 . The sealing portion 321 and the support portion 323 are connected by a portion to be broken 324 having a reduced diameter. The sealing portion 321 has a fitting portion 321a and a flange portion 321b. The fitting portion 321a has a diameter that can be press-fitted into the flavoring inlet 105, for example, while the flange portion 321b has a larger diameter than the flavoring inlet 105. As shown in FIG. After injecting the liquid flavoring into the holding space 231 from the flavoring inlet 105, the user fits the fitting portion 321a of the sealing portion 321 to the flavoring inlet 105, and breaks the breaking portion 324 to seal. The stop portion 321 is separated from the support portion 323 . Thereby, as shown in FIG. 28, the perfume injection port 105 can be closed.

<4. Modified Example of Perfume Cartridge>
Although the configuration example of the perfume cartridge 200 according to this embodiment has been described so far, the perfume cartridge 200 according to this embodiment can be modified in various ways.

FIG. 29 is an exploded perspective view showing the configuration of a perfume cartridge 200A according to a modification. The perfume cartridge 200A according to the modification differs from the perfume cartridge 200 according to the embodiment in that it has only one holding space 231 in which the perfume holder 261 is arranged. Corresponding to the provision of one holding space 231, the first opening (221) and the first rib 235 of the first case body 211, the communication hole 101 of the second case body 100 and the perfume injection port 105 are also provided one by one.

In a modified example, a perfume holder 261 is arranged in one cylindrical holding space 231 . The perfume holder 261 is substantially cylindrical and arranged over substantially the entire region except for the ventilation region A. As shown in FIG. The perfume holder 261 is configured by forming a plurality of fragile portions 264 formed by cutting lines on one side of a sheet-like impregnation material 262 . Therefore, even if the sheet-like impregnation material 262 has relatively high bending rigidity, it can be easily bent according to the shape of the holding space 231 . Therefore, the perfume holder 261 is easily accommodated in the cylindrical holding space 231 as well.

As described above, according to the perfume cartridge 200 according to the present embodiment, the perfume holder 251 arranged in the holding space 231 having a curved cross-sectional shape has the fragile portion 254 that reduces the bending rigidity. Therefore, the perfume holder 251 having relatively high flexural rigidity and relatively enhanced liquid perfume impregnation property and resistance to the liquid perfume can be easily arranged in the holding space 231 having a curved or bent cross-sectional shape. . For example, a fragile portion formed by continuously or intermittently forming cut lines, grooves, or holes is provided on a line along a predetermined direction that intersects the bending direction of the flavoring material holder 251, so that the flavoring material holder 251 can be easily bent in a desired direction, and can be easily arranged in the holding space 231 .

Further, in the perfume cartridge 200 according to the present embodiment, the perfume holder 251 can be easily arranged in the holding space 231 having a curved or bent cross-sectional shape. A perfume carrier 251 can be used.

Further, the perfume cartridge 200 according to this embodiment includes the first rib 235 as a restricting portion that restricts the movement of the perfume holder 251 toward the ventilation region A side. Therefore, it is possible to reduce the risk that the perfume holder 251 will enter the ventilation area A and obstruct the flow of air passing through the ventilation area A. Therefore, the ventilation resistance of the air passing through the ventilation region A is reduced, and the decrease in the flow rate of the fragrance released from the fragrance providing device 1 can be suppressed.

Further, the perfume cartridge 200 according to this embodiment includes a perfume injection port 105 for injecting a desired liquid perfume into the holding space 231 in which the perfume holder 251 is arranged. Therefore, the user can use the fragrance providing device 1 by injecting any liquid fragrance. Since the perfume holder 251 has the predetermined dam 253 , it is possible to prevent the liquid perfume from entering the ventilation region A when the liquid perfume is injected into the holding space 231 .

Further, in the perfume cartridge 200 according to the present embodiment, ribs 115 are provided in the communication holes 101 that serve as ventilation holes provided on the same surface as the perfume injection port 105 . Therefore, it is possible to prevent a jig for injecting the liquid fragrance from being erroneously inserted into the communication hole 101 . Thereby, it can suppress that a liquid fragrance|flavor penetrates into the ventilation area|region A. As shown in FIG.
