[0011] [First embodiment] First, the first embodiment will be described with reference to Figures 1 to 14(b). In all the drawings, the same components are denoted by the same reference numerals, and duplicated descriptions will be omitted where appropriate. In the following, when describing the positional relationship of each component of the dissipation device 400, the upper side in FIGS. 4 and 5 will be referred to as the upper side or upper side, and the opposite side will be referred to as the lower side or lower side. Furthermore, the left side in FIGS. 6 and 7 will be referred to as the front side (front side) or front, and the opposite side will be referred to as the rear side (rear side) or rear. Furthermore, a direction perpendicular to both the up-down direction and the front-to-rear direction will be referred to as the left-to-right direction or width direction. Furthermore, when describing the positional relationship of each component of the housing 200, the side on which the container 100 is located in the up-down direction, front-to-rear direction, and left-to-right direction will be referred to as the inner side (inside), and the side opposite the inner side will be referred to as the outer side (outside). However, these directional specifications are for convenience only and do not limit the orientation of the dissipation device 400 during manufacture or use.

[0012] As shown in Figure 3, the diffusion device 400 of this embodiment is a diffusion device 400 that diffuses volatile components, and includes a container 100 that contains contents 150 containing volatile components, a housing 200 that holds the container 100, and a magnet 300 that is provided in the housing 200 and attracts the diffusion device 400 to a target surface 510 (Figures 6 and 7, etc.). Note that the term "adhesion" used here does not mean a weak adhesivity, but rather adhering with a magnetic force strong enough to allow the dissipation device 400 to be attached to the target surface 510, such as a vertical surface, horizontal surface, or ceiling surface, while supporting the weight of the housing 200 itself. Furthermore, the target surface 510 here refers to a surface configured to be able to attract the magnet 300 using a ferromagnetic material, and is typically a wall surface 620 or ceiling surface 630 of the bathroom 600, which may include a steel plate, iron plate, stainless steel plate, etc. (see Figure 13).

[0013] According to this embodiment, the dissipation device 400 includes the magnet 300 that attracts the dissipation device 400 to the target surface 510, and therefore the dissipation device 400 can be easily attached to the target surface 510 and detached from the target surface 510. Therefore, the dissipation device 400 can be easily installed in a position where it can efficiently dissipate volatile components depending on the usage environment of the dissipation device 400 (for example, the humidity and air volume in the installation space).

[0014] In this embodiment, the contents 150 are liquid. More specifically, as an example, the contents 150 are liquids containing a volatile antifungal component and a non-volatile solvent (e.g., water). The volatile antifungal component is not particularly limited, but an example thereof is trans-2-hexenal, which is an antifungal fragrance composition. However, in the present invention, the volatile component contained in the contents 150 is not limited to this example, and may be, for example, a volatile deodorizing component. Furthermore, in the present invention, the contents 150 are not limited to liquids, but may be in the form of a gel, powder, or granules, or the liquid contents 150 may be impregnated into a pulp mat, nonwoven fabric, porous body, or the like.

[0015] As shown in FIG. 13, the diffusion device 400 is installed, for example, in a bathroom 600, and is used to prevent the growth of mold and bacteria on the floor, wall, and ceiling surfaces, etc., by diffusing (volatilizing) the anti-fungal components contained in the contents 150, and to impart a fragrance to the indoor space. As described above, the diffusing device 400 is provided with a magnet 300 that attracts the diffusing device 400 to the target surface 510. This makes it easy to install the diffusing device 400 on a wall surface 620 or ceiling surface 630 of a bathroom 600, as shown in Fig. 13. Therefore, for example, by installing the diffusing device 400 on a wall surface 620 or ceiling surface 630 near a window or door where outside air can easily flow in, the antifungal component can be efficiently diffused widely throughout the space. As will be described later, in this embodiment, the dissipation device 400 is supported by the stand member 280 and is therefore freestanding, so it can be placed on a horizontal mounting surface 520 such as a shelf, the edge of the bathtub, or the floor in the bathroom 600. As will be described later, the dissipation device 400 has a hook hole 209 for hanging a hanging member such as a hook or clip, so that it can be installed while suspended from such a hanging member. In this way, the dissipation device 400 according to this embodiment can be attached to the target surface 510, and can also be installed in a freestanding state on the placement surface 520 or hung from a hanging member, thereby ensuring sufficient freedom in the installation location of the dissipation device 400. Therefore, the dissipation device 400 can be more easily installed in a position where it can efficiently dissipate volatile components depending on the environment in which the dissipation device 400 is used. In the present invention, the installation location of the dissipation device 400 is not limited to a bathroom, but may be appropriately installed in, for example, a dressing room, a toilet, a kitchen, a closet, a storage space, a vehicle, or other interior space.

[0016] As shown in Figures 5 and 6, the housing 200 has an opposing surface 201 (in this embodiment, the back surface of the housing 200) that faces the target surface 510, and the part of the opposing surface 201 that protrudes most toward the target surface 510 forms an adsorption section 242 (in this embodiment, the opening of the storage section 251) that is adsorbed to the target surface 510 by the magnetic force of the magnet 300, and a diffusion hole 243 that diffuses volatile components is formed in the opposing surface 201 at a part (in this embodiment, the annular section 241 described later) that moves away from the target surface 510 while the adsorption section 242 is adsorbed to the target surface 510. With this configuration, when the dissipation device 400 is adsorbed to the target surface 510, a gap is formed between the target surface 510 and the dissipation hole 243, so that the volatile components can be efficiently dissipated to the outside of the housing 200 through the dissipation hole 243. However, in the present invention, the location where the diffusion holes 243 are formed in the housing 200 is not limited to the rear surface of the housing 200, but may be the front surface, side surface, top surface, bottom surface, etc. of the housing 200, for example.

[0017] Furthermore, in this embodiment, the container 100 is detachable from the housing 200 . According to this configuration, of the container 100 and the housing 200 of the dissipation device 400, the container 100 can be disposable and the housing 200 can be reused. More specifically, after removing the used container 100 from the housing 200, a new container 100 can be stored in the housing 200, and the housing 200 and the new container 100 can be subsequently used as the dissipation device 400. At the distribution stage such as sales, the container 100 may be handled as a set with the housing 200, or the container 100 alone (separate from the housing 200).

[0018] 1 and 4, in this embodiment, the housing 200 has a sight window 205 that allows the container 100 to be viewed from the outside. The portion of the container 100 that can be viewed from the outside through the sight window 205 (in this embodiment, a central portion 22 of the container section 20, which will be described later) is configured to allow the liquid inside the container 100 to be seen through the sight window 205, and has a larger liquid capacity per unit area than the portions of the container 100 located to the sides of the sight window 205 (in this embodiment, both side portions 23 of the central portion 22, which will be described later). Note that the "liquid capacity per unit area" here is a value obtained by multiplying a unit area in a plane perpendicular to the viewing direction of the dissipation device 400 (the thickness direction of the housing 200) by the depth dimension of the container 100 in the viewing direction. According to this configuration, the portion of the container 100 that can be seen from the outside through the viewing window 205 (the central portion 22 of the container 20) can be used as a liquid level monitor (indicator) that notifies the user when it is time to replace the container 100 as the content 150 decreases (or disappears). This allows the user to replace the used container 100 with a new container 100 at an appropriate time. More specifically, since the contents 150 are a liquid containing volatile components as described above, as time passes from the start of use of the container 100 and the volatile components evaporate, the liquid volume of the contents 150 decreases and the liquid level 150a of the contents 150 inside the container 100 drops (see FIGS. 14(a) and 14(b)). The user can then visually check the drop in the liquid level 150a of the contents 150 inside the container 100 from the outside through the viewing window 205, thereby knowing when it is time to replace the container 100. Note that the contents 150 are shown hatched in FIGS. 14(a) and 14(b). More specifically, in this embodiment, the contents 150 contain a volatile liquid (volatile components) and a non-volatile liquid, and in a used container 100 from which the volatile components contained in the contents 150 have sufficiently dissipated, the non-volatile liquid contained in the contents 150 remains in the storage section 20. In this way, even if the storage section 20 of a used container 100 is not emptied (i.e., the contents 150 are not completely lost), by using a portion of the container 100 visible from the outside through the viewing window 205 (the central portion 22 of the storage section 20) as a liquid level monitor as described above, the user can easily know when to replace the container 100. Also, for example, a portion with a relatively large liquid capacity per unit area is provided within the container 100 as described above, and this portion is used as the liquid level monitor. Therefore, even if the content 150 contains a small proportion of volatile liquid and the amount of content 150 that decreases with use is small, the liquid level 150a in the liquid level monitor can be sufficiently lowered and the liquid level 150a can be made to be a nearly flat liquid level that is easy to see. In the present embodiment, as an example, it is preferable that liquid level 150a of content 150 falls below the lower end of sight window 205 at the time when substantially all of the volatile liquid contained in content 150 has dissipated. With this configuration, the user can determine when it is time to replace container 100 by using the fact that liquid level 150a can no longer be seen through sight window 205 as an indicator. In the present invention, the housing 200 does not necessarily have to have the viewing window 205. In that case, for example, a seal member indicating the start date of use of the container 100 may be attached to the housing 200, so that it is possible to know when to replace the container 100. In the present invention, the entire content 150 may be a volatile liquid. In such a case, for example, the housing 200 is preferably configured so that it is possible to visually confirm from the outside through the viewing window 205 that the entire amount of the content 150 in the storage section 20 has disappeared.

[0019] As shown in FIG. 7, the housing 200 has a protrusion 232 that presses the film 90 toward the main body case 10 side. This configuration restricts bending (expansion) of the film 90 toward the side opposite to the main body case 10 (in this embodiment, the rear (back side)), and suppresses a drop in the liquid level 150a of the contents 150 due to bending of the film 90 (i.e., not due to a decrease in the contents 150). Therefore, good reproducibility of changes in the liquid level monitor (changes in the liquid level 150a of the contents 150) can be achieved.

[0020] 9, 10(a), and 10(b), container 100 has main case 10 having opening 12 and containing contents 150 therein, and film 90 that closes opening 12 of main case 10 and allows volatile components to pass through to the outside. Contents 150 (more specifically, antifungal components contained in contents 150) are dispersed to the outside of container 100 through film 90.

[0021] The main body case 10 has, for example, an opening 12 and, when contents 150 are housed inside, includes a flange portion 40 that protrudes from the opening 12 to the outer periphery. 10(a) and 10(b), the storage section 20 is a hollow section that bulges forward from the flange section 40, and contents 150 are stored inside the storage section 20. The rear end side of the storage section 20 opens rearward to form an opening 12. As shown in FIG. 9, the outer shape of the storage section 20 is formed, for example, in a circular shape when viewed from the front. The flange portion 40 has an outer shape that tapers gradually upward in a teardrop shape when viewed from the front. A rib 41 that bulges forward is formed at the upper end of the flange portion 40. The rib 41 extends linearly in the width direction, for example. Here, the middle portion 21 (middle in the up-down direction) of the storage portion 20 is recessed further rearward than both end portions 25 (upper end and lower end) of the storage portion 20, and its depth dimension is smaller than the depth dimension of both end portions 25. Furthermore, the central portion 22 in the width direction of the middle portion 21 bulges slightly forward more than the pair of left and right side portions 23 (both end portions in the width direction) of the middle portion 22 of the middle portion 21, and has a larger liquid capacity per unit area than the pair of left and right side portions 23. In the case of this embodiment, the central portion 22 is a portion of the storage device 100 that can be seen from the outside through the observation window 205, and the user can know when to replace the storage device 100 by using the change in the liquid level 150a of the contents 150 in the central portion 22 as an indicator. As shown in Fig. 9, the width of the central portion 22 gradually increases toward the center in the vertical direction. Similarly, as shown in Fig. 10(a) and Fig. 10(b), the depth (dimension in the front-rear direction) of the central portion 22 also gradually increases toward the center in the vertical direction. Furthermore, as shown in Fig. 10(b), the depth of both end portions 25 (upper end and lower end) of the storage portion 20 gradually decreases toward the boundary with the central portion 22. In this embodiment, for example, the maximum depth dimension D1 of the central portion 22 (see Figure 10(a)) is preferably 1 / 6 to 2 / 3 of the maximum depth dimension D2 of each of the side portions 23 (see Figure 10(a)), and more preferably 1 / 5 to 1 / 2 of the depth dimension D2. The width dimension of the central portion 22 is smaller than the width dimension of each of the end portions 25 (upper end and lower end) of the storage portion 20. More specifically, the maximum width dimension W1 (see FIG. 9) of the central portion 22 is preferably 1 / 6 to 1 / 2 of the width dimension W2 (see FIG. 9) of each of the end portions 25 (upper end and lower end) of the storage portion 20, and more preferably 1 / 5 to 1 / 3 of the width dimension. Furthermore, the maximum depth dimension of the central portion 22 is smaller than the depth dimension of each of the end portions 25 (upper end and lower end) of the storage portion 20. More specifically, the maximum depth dimension D1 of the central portion 22 is preferably 1 / 6 to 2 / 3 of the maximum depth dimension D3 (see FIG. 10(a)) of each of the end portions 25 (upper end and lower end) of the storage portion 20, and more preferably 1 / 5 to 1 / 2 of the depth dimension. This configuration ensures a sufficient liquid volume in the central portion 22, which is the portion visible from the outside through the sight window 205. This prevents the liquid surface 150a of the contents 150 in the central portion 22 from becoming concave or wavy due to surface tension. In other words, the liquid surface 150a can be made nearly flat and easily visible, making it easy to grasp the remaining amount of contents 150 in the liquid level monitor (central portion 22). In this embodiment, the contents 150 can flow into the entire storage section 20, including the above-mentioned both side sections 23. The inner diameter of the opening 12 is set to be equal to the inner diameter of the storage section 20. With this configuration, the portion of container 100 that can be seen from the outside through sight window 205 (central portion 22) can be locally narrowed, while still ensuring a sufficient contact area between contents 150 and film 90 through opening 12. Therefore, volatile components contained in contents 150 can be efficiently dissipated through film 90. More specifically, the liquid capacity per unit area of ​​both side sections 23 is set to be smaller than that of central section 22, which serves as a liquid level monitor as described above, but the contents 150 can be sucked up and flow into both side sections 23 by capillary action as well. Therefore, the contact area between the contents 150 and film 90 can be satisfactorily secured in both side sections 23 as well. Furthermore, in this embodiment, a pair of left and right side portions 23 are each formed with a protrusion 28 that protrudes toward the film 90. As shown in Fig. 7, the protrusion 28 is capable of coming into contact with, for example, the inner surface of the film 90 (the surface on the storage section 20 side). With this configuration, even if the film 90 is recessed toward the main case 10 due to reduced pressure inside the main case 10, the inner surface of the film 90 and the inner surfaces of both side sections 23 will be in full contact with each other, preventing the contents 150 from being prevented from flowing into both side sections 23. Therefore, even if the remaining liquid amount of the contents 150 inside the main case 10 decreases, the contact area between the contents 150 and the film 90 can be stably secured. The shape of the protrusion 28 is not particularly limited, but as an example, it is formed in a semi-spherical (dome-like) shape that is convex toward the film 90 side. In the present invention, the shape of the main body case 10 is not limited to the above example, and can be set appropriately depending on the shape of the housing 200, the use of the dissipation device 400, and the like.

[0022] As shown in Figures 9, 10(a) and 10(b), the film 90 is positioned on the rear side of the main body case 10 and is joined to the peripheral edge of the opening 12 in the flange portion 40, thereby circumferentially closing the opening 12. Furthermore, in the case of this embodiment, as shown in Figures 10(a) and 10(b), before use of container 100 begins, container 100 is easily releasably joined to main case 10 and further includes release film 95 covering film 90. When container 100 is to be used, release film 95 is peeled off and film 90 is exposed to the outside, and container 100 is housed inside housing 200. With this configuration, before use of container 100 begins, release film 95 prevents content 150 from dissipating to the outside of container 100, and after use of container 100 begins, content 150 can be effectively dissipated to the outside of container 100 via film 90. The outer shape of the release film 95 is set to, for example, the same shape and dimensions as the outer shape of the flange portion 40. As shown in Figures 9, 10(a) and 10(b), the release film 95 covers the entire flange portion 40 and the film 90 from the rear side.

[0023] The main body case 10 is integrally molded from, for example, a resin material that is transparent to visible light, so that the contents 150 in the storage section 20 can be seen from the outside. The material of the film 90 is not particularly limited, but examples thereof include polyethylene, polypropylene, ethylene vinyl acetate, and nonwoven fabric. The material of the release film 95 is not particularly limited, but examples thereof include polyethylene terephthalate, nylon, and aluminum.

[0024] As shown in FIGS. 1 to 3, the housing 200 has a first member 220 and a second member 230 that are assembled together to house and hold the container 100. 8, the dissipation device 400 can stand on its own without the magnetic force of the magnet 300, in a state where the first bottom 221, which is the bottom of the first member 220, and the second bottom 231, which is the bottom of the second member 230, are in contact with the ground. More specifically, the housing 200 can stand on its own on the placement surface 520 only by the housing main body 210 (described in detail later) formed by the first member 220 and the second member 230. In addition, in FIG. 8, the container 100 is indicated by a two-dot chain line. The first bottom 221 and the second bottom 231 are spaced apart from each other, and the gap between the first bottom 221 and the second bottom 231 forms a drain hole 208 that allows water that has entered the housing 200 to be discharged downward. With this configuration, even if the dissipation device 400 is installed in a freestanding state in a moist environment such as a bathroom, water that has entered the housing 200 can be efficiently discharged, and the inside of the housing 200 can be kept clean. In the present invention, the location of the drain hole 208 is not limited to the above example, but may be any location that allows at least water that has entered the housing 200 to be discharged downward when the dissipation device 400 is standing on the mounting surface 520. Furthermore, in the present invention, as in a second embodiment described later, the housing 200 may be made self-standing by a member other than the housing main body 210 (for example, a stand member 280).

[0025] In this embodiment, the housing main body 210 is configured by assembling the first member 220 and the second member 230 in a detachable manner. The first member 220 constitutes the front side of the housing main body 210, and the second member 230 constitutes the rear side of the housing main body 210. The housing body 210 is a hollow member, and is formed, for example, in a generally teardrop shape tapering upward. As shown in Figures 3 and 7, the housing body 210 accommodates the container 100 inside. When storing the container 100 in the housing main body 210, first, the second member 230 is removed from the first member 220. Then, with the container 100 disposed between the first member 220 and the second member 230, the first member 220 and the second member 230 are assembled together. As shown in FIG. 7, the container 100 is housed inside the housing body 210 so that the surface of the container 100 facing the film 90 (back surface) is positioned on the second member 230 side, and the surface of the container 100 opposite the film 90 side (front surface) is positioned on the first member 220 side.

[0026] 1 and 3, the first member 220 has a front portion 220a that forms the front surface of the housing main body 210, and a first peripheral wall portion 220b that protrudes circumferentially rearward from the outer periphery of the front portion 220a. As shown in FIG. 7, the entire front portion 220a is curved in an arc shape toward the front, and the front surfaces of both end portions 25 of the container 100 (the surfaces opposite to the film 90 side) fit into the inner surface of the curved portion of the front portion 220a. 1 and 4, a gap is formed in the center of front portion 220a, and this gap constitutes sight window 205 through which container 100 can be seen from the outside. Note that, as shown in Fig. 7, the outer periphery of sight window 205 in front portion 220a is recessed rearward toward sight window 205. The sight window 205 penetrates the front portion 220a in the thickness direction and is formed in a circular shape when viewed from the front. The inner diameter of the sight glass 205 is set to be slightly larger than the maximum width dimension W1 of the central portion 22 of the container 100 (the portion of the container 100 that can be seen from the outside through the sight glass 205), and is set to be slightly smaller than the vertical dimension of the central portion 22 (same as above). Furthermore, a hook hole 209 for hanging a hanging member such as a hook or clip is formed at the upper end of the front surface portion 220a. The hook hole 209 penetrates the front surface portion 220a in the thickness direction.

[0027] 11(a) and 11(b), a plurality of first protrusions 225a protruding toward the center of the first member 220 are formed on the inner surface of the outer circumferential edge of the front portion 220a of the first member 220. Each of the plurality of (e.g., six) first protrusions 225a is arranged intermittently and symmetrically with respect to the center of the first member 220. As shown in FIG. 7, the rear end surface of each first protrusion 225a abuts against the front end surface of the second member 230 (more specifically, the side wall portion 257b described later), thereby restricting relative forward displacement of the second member 230 with respect to the first member 220. 7, 11(a), and 11(b), a pair of left and right second protrusions 225b extending in the front-to-rear direction are formed on the inner surface of the upper end portion of the first peripheral wall portion 220b of the first member 220. As shown in Fig. 5, the lower end surfaces of the pair of left and right second protrusions 225b each abut against the upper end of the second member 230 (more specifically, a pair of left and right overhanging portions 257 described later), thereby restricting the relative upward displacement of the second member 230 with respect to the first member 220. 5 and 6, a plurality of protrusions 226 are formed on the inner surface of the first peripheral wall portion 220b of the first member 220. The protrusions 226 protrude toward the center of the first member 220 and extend along the circumferential direction of the first peripheral wall portion 220b. The plurality of (e.g., four) protrusions 226 are arranged symmetrically with respect to the center of the first member 220 and are arranged intermittently in the circumferential direction of the first peripheral wall portion 220b. As shown in FIG. 5, the tip end surface (the tip end in the protruding direction) of each of the plurality of protrusions 226 abuts against the outer peripheral surface of the second member 230 (more specifically, a groove portion 258 described later), thereby allowing the second member 230 to fit well with the first member 220. According to this configuration, rattle between the first member 220 and the second member 230 can be suppressed, and the first member 220 and the second member 230 can be easily assembled to each other in a detachable manner.

[0028] The second member 230 has a rear portion 230a that constitutes the rear surface of the housing main body 210, and a second peripheral wall portion 241b that protrudes in a circumferential shape from the outer periphery of the rear portion 230a toward the first member 220 side. The back surface portion 230a includes an annular portion 241 formed in a substantially annular shape when viewed from the front, and a housing portion 251 formed in the center of the annular portion 241 and housing the magnet 300 therein.

[0029] 2 and 6, in this embodiment, the annular portion 241 has a shape that gradually rises rearward (toward the target surface 510) from its radially outer side toward its radially inner side. The inner peripheral edge of the annular portion 241 protrudes furthest toward the target surface 510, and the opening of the accommodation portion 250 (described in detail later) connected to the inner peripheral edge is the portion of the back surface portion 230a that protrudes furthest toward the target surface 510 (the suction portion 242 described above). In the annular portion 241, the portion directly above the center of the annular portion 241 (the portion at the 12 o'clock direction in Figure 5) and its surroundings are, for example, slightly convex curved toward the side opposite to the first member 220, and the other portions are curved toward the first member 220.

[0030] 2, 5, 12(a) and 12(b), a plurality of diffusion holes 243 that diffuse the volatile components described above are formed in the annular portion 241. More specifically, in the present embodiment, the plurality of diffusion holes 243 are formed in a 360-degree range along the circumferential direction of the annular portion 241. Each of the plurality of diffusion holes 243 penetrates the annular portion 241 in the thickness direction, and extends linearly along the radial direction of the annular portion 241 when viewed from the front, for example, and these plurality of diffusion holes 243 are arranged radially with the center of the annular portion 241 as the reference point. The width dimension of each of the plurality of diffusion holes 243 (the dimension in the direction perpendicular to the extending direction) gradually decreases from the outer side to the inner side in the radial direction of the annular portion 241. Like the annular portion 241, each of the plurality of diffusion holes 243 also has a shape that gradually rises rearward from the radially outer side of the annular portion 241 toward the radially inner side. Of the multiple diffusion holes 243, the length dimension (dimension in the extension direction) of the diffusion holes 243 formed in the upper half of the annular portion 241 is larger than the length dimension (same as above) of the diffusion holes 243 formed in the lower half of the annular portion 241. The total opening area of ​​the plurality of diffusion holes 243 is preferably, for example, 1 / 6 to 5 / 6 of the surface area of ​​the rear surface portion 230a, and more preferably 1 / 3 to 2 / 3 of the surface area of ​​the rear surface portion 230a. With this configuration, the volatile components contained in the contents 150 can be efficiently dissipated through the multiple dissipation holes 243 while ensuring sufficient structural strength of the annular portion 241 and therefore the housing main body 210. The shape and number of the plurality of diffusion holes 243 are not limited to the example shown in FIG. 5 and the like, and can be set appropriately depending on the shape of the housing body 210, the use of the diffusion device 400, and the like.

[0031] 7, the accommodation portion 251 is a recess that is recessed from the inner peripheral edge of the annular portion 241 toward the first member 220, and has an opening that opens toward the rear. The magnet 300 is accommodated inside the accommodation portion 251 through the opening of the accommodation portion 251. The opening is open in the center of the annular portion 241, and is the portion (adsorption portion 242) on the back surface portion 230a that protrudes most toward the target surface 510. The adsorption portion 242 (opening of the storage portion 251) has a flat surface and is configured to come into surface contact with the target surface 510 in a circumferential manner. In rear view, the opening of the accommodation portion 251 is arranged concentrically with the annular portion 241. The housing portion 251 is formed, for example, in a hollow, generally disk-like shape with its axial direction extending in the front-rear direction. The front end side of the housing portion 251 is closed by a main surface portion 251a. As shown in Fig. 3, magnet 300 is formed in a disk shape. As shown in Fig. 7, when magnet 300 is housed inside housing portion 251, one main surface of magnet 300 is arranged along main surface portion 251a of housing portion 251, and the other main surface of magnet 300 is exposed from housing 200 to the target surface 510 side. Magnet 300 may be fixed to housing portion 251 by fitting into housing portion 251, or may be fixed to housing portion 251 with an adhesive (not shown). The inner diameter of the storage portion 251 is set to, for example, a dimension that is approximately equal to or slightly larger than the outer diameter of the magnet 300. The depth dimension of the storage portion 251 is set to a dimension that is slightly larger than the thickness dimension of the magnet 300. Furthermore, the other main surface of magnet 300 (the surface opposite to main surface portion 251a) is located closer to first member 220 than attraction portion 242. In other words, attraction portion 242 protrudes toward target surface 510 than the other main surface of magnet 300. Then, in a state in which attraction portion 242 (opening of accommodating portion 251) of dissipation device 400 is attracted to target surface 510, the other main surface of magnet 300 is spaced apart from target surface 510. That is, in the case of this embodiment, of the opening of accommodating portion 251 and magnet 300, the opening of accommodating portion 251 selectively comes into direct contact with target surface 510 due to the magnetic force of magnet 300. According to this configuration, even if the dissipation device 400 is attracted to the target surface 510 for a long period of time, it is possible to prevent the magnet 300 from leaving a mark on the target surface 510. However, the present invention is not limited to this example, and both the opening of the storage section 251 and the magnet 300 may be in direct contact (adsorbed) with the target surface 510, or the opening of the storage section 251 and the magnet 300, of which the magnet 300 may be selectively in direct contact (adsorbed) with the target surface 510. As an example, a neodymium magnet or an anisotropic ferrite magnet can be used as magnet 300. If magnet 300 is a neodymium magnet, it is preferable that the outer diameter of magnet 300 is 5 mm or more and 15 mm or less, and the thickness of magnet 300 is 1 mm or more and 5 mm or less. If magnet 300 is an anisotropic ferrite magnet, it is preferable that the outer diameter of magnet 300 is 20 mm or more and 35 mm or less, and the thickness of magnet 300 is 2 mm or more and 8 mm or less. In the present invention, the shape of magnet 300 is not limited to the disk shape described above, and may be, for example, a flexible, thin sheet (magnet sheet). In this case, ferrite can be used as the magnetic material constituting magnet 300 (magnet sheet).

[0032] 3 and 12(a), in this embodiment, the above-mentioned protrusion 232 that presses the film 90 toward the main case 10 is formed on the lower half of the annular portion 241. The protrusion 232 protrudes, for example, from the annular portion 241 toward the main case 10 side (the first member 220 side). The protrusion 232 is formed, for example, in a substantially cylindrical shape with an axial direction that includes a component in the front-to-rear direction, and is open on both the first member 220 side and the side opposite to the first member 220 side. The protrusion 232 is formed, for example, in a substantially oval shape that is elongated in the up-down direction when viewed from behind, and the width dimension of the protrusion 232 slightly decreases upward. The end (front end) of protrusion 232 on the main body case 10 side is formed flat, and is configured to be able to make circumferential surface contact with the back surface of film 90. In the present invention, it is sufficient that at least a portion of protrusion 232 presses against film 90, and for example, a gap may be formed between a part of the front end of protrusion 232 and the back surface of film 90 depending on the degree of bending of film 90. 12(a), in rear view, protrusion 232 is formed at a position corresponding to, for example, one of the plurality of diffusion holes 243 (for example, diffusion hole 243 located at the 6 o'clock direction in FIG. 12(a)), and diffusion hole 243 is formed by an opening on the rear end side of protrusion 232. With this configuration, protrusion 232 can restrict bending (bulging) of film 90 toward the side opposite to main body case 10 (in this embodiment, the rear side of housing 200), while ensuring the opening area of ​​diffusion hole 243 in annular portion 241. The protrusion height H1 (see Figure 7) of the protrusion portion 232 is preferably, for example, a height that allows it to abut directly (or via the film 90) against the flange portion 40 within the housing 200, or a height that allows the film 90 to be slightly pushed into the interior of the storage portion 20.

[0033] Furthermore, as shown in FIG. 5 and other figures, the second member 230 includes a pair of left and right protrusions 257 that protrude radially outward from the annular portion 241 from the front end (the end on the first member 220 side) of the second circumferential wall portion 241b. Each of the pair of left and right protrusions 257 extends upward from the lower end of the second circumferential wall portion 241b along the circumferential direction of the annular portion 241. Furthermore, the upper end of each of the pair of left and right protrusions 257 protrudes upward from the upper end of the second circumferential wall portion 241b while linearly inclining in directions approaching each other. More specifically, each of the pair of left and right protrusions 257 includes a planar portion 257a formed in a flat plate shape, and a side wall portion 257b protruding from the outer edge of the planar portion 257a toward the first member 220. As shown in Fig. 5, the outer surface of each of the side wall portions 257b of the pair of left and right overhanging portions 257 is disposed along the inner surface of the first circumferential wall portion 220b of the first member 220. This makes it possible to restrict the second member 230 from being displaced relative to the first member 220 around the central axis of the second member 230. Furthermore, the upper end portion of each of the pair of left and right overhanging portions 257 abuts against the corresponding second protrusion 225b of the first member 220. This makes it possible to restrict the second member 230 from being displaced upward relative to the first member 220, as described above. Further, a groove 258 is formed on the outer peripheral surface of each side wall portion 257b of the pair of left and right protrusions 257. Each of the pair of left and right grooves 258 extends along the circumferential direction of the annular portion 241 and is open radially outward and rearward of the annular portion 241. As shown in FIG. 5, the multiple protrusions 226 of the first member 220 fit into the corresponding grooves 258. As a result, the pair of left and right protrusions 257 of the second member 230 fit into the first circumferential wall portions 220b of the first member 220, and the first member 220 and the second member 230 are properly assembled to each other. Furthermore, a finger hook 256 for hooking a user's finger is formed at the upper end of the annular portion 241 of the first member 220. The finger hook 256 protrudes upward, for example, from the outer periphery of the upper end of the annular portion 241. As shown in FIG. 6, the finger hook 256 is slightly curved in a convex arc shape toward the rear. As shown in FIGS. 12(a) and 12(b), in this embodiment, the finger hook 256 is disposed between a pair of left and right protrusions 257 in the circumferential direction of the annular portion 241. When replacing the container 100 in the housing main body 210, the user can easily remove the second member 230 from the first member 220 by hooking their finger on the finger hook 256 and pulling the second member 230 rearward (toward the back side).

[0034] 7, when the container 100 is housed inside the housing main body 210, the film 90 and the annular portion 241 (and hence the diffusion holes 243) are spaced apart from each other in the front-to-rear direction. The front surface of each of the planar portions 257a of the pair of left and right protrusions 257 abuts against the rear end surface of the flange portion 40 of the main body case 10, thereby restricting rearward displacement of the main body case 10 relative to the second member 230. 12(a), in this embodiment, a plurality of (for example, four) third protrusions 259 protruding radially inward are formed on the inner circumferential surfaces of the side wall portions 257b of the pair of left and right protrusions 257. The front end surface of the flange portion 40 of the main body case 10 abuts against each of the plurality of third protrusions 259, thereby restricting forward displacement of the main body case 10 relative to the second member 230. 5, a portion of the outer peripheral edge of flange portion 40 is disposed along the inner peripheral surfaces of side wall portions 257b of the pair of left and right protrusion portions 257. This makes it possible to suppress rattling of container 100 relative to second member 230 and therefore housing main body 210. 7, the front end of the protrusion 232 that presses the film 90 toward the main body case 10 abuts against the lower end of the film 90 and part of the flange 40, for example.

[0035] 8, in this embodiment, a first bottom portion 221, which is the bottom portion of the first member 220, is formed at the lower end portion of the first circumferential wall portion 220b. The first bottom portion 221 is formed flat in its entirety. Furthermore, second bottom portion 231, which is the bottom portion of second member 230, is formed, for example, over a portion of the lower end of annular portion 241, the lower end of second circumferential wall portion 241b, and a portion of side wall portion 257b. Second bottom portion 231 is formed flat throughout. The lower end of first circumferential wall portion 220b and the lower end of second circumferential wall portion 241b are spaced apart from each other in the thickness direction (front-to-back direction) of housing 200, and the gap in the thickness direction between the lower end of first circumferential wall portion 220b and the lower end of second circumferential wall portion 241b constitutes the above-mentioned drainage hole 208. The drain hole 208 is located, for example, below the protrusion 232 in the housing 200. The drain hole 208 allows the inside and outside of the housing 200 to communicate with each other. 6, in this embodiment, the thickness dimension of the second member 230 gradually increases downward. More specifically, the thickness dimension of the lower end of the second member 230 is greater than the thickness dimension of the upper end. According to this configuration, the formation area of ​​the second bottom portion 231 can be sufficiently secured in the second member 230, and therefore the second bottom portion 231 allows the housing 200 to stand stably on the placement surface 520 by itself.

[0036] 6 and 7, in the present embodiment, when the dissipation device 400 is attracted to the target surface 510 by the magnetic force of the magnet 300, each of the plurality of diffusion holes 243 is spaced apart from the target surface 510. In addition, the attracting portion 242 (the opening of the accommodating portion 250) is in circumferential contact with the target surface 510, while the magnet 300 is spaced apart from the target surface 510. As shown in FIG. 8, when the dissipation device 400 is standing on the support surface 520, the first bottom 221 of the first member 220 and the second bottom 231 of the second member 230 are each in contact with the support surface 520 in their entirety. Here, in this embodiment, when the dissipation device 400 is attached to the target surface 510, the inclination angle R1 (see Figure 7) of the dissipation device 400 (more specifically, the imaginary straight line 610 extending in a direction perpendicular to the depth direction of the storage unit 100) with respect to the horizontal surface 530, and when the dissipation device 400 is freestanding on the storage surface 520, the inclination angle R2 (see Figure 8) of the dissipation device 400 (more specifically, the imaginary straight line 610 extending in a direction perpendicular to the depth direction of the storage unit 100) with respect to the horizontal surface 530 (the storage surface 520) are approximately equal to each other. With this configuration, the height position of the liquid surface 150a of the contents 150 can be aligned in both a state where the dissipation device 400 is adsorbed to the target surface 510 and a state where the dissipation device 400 is standing independently on the placement surface 520. This ensures the reproducibility of the liquid level monitor (the central portion 22 of the storage section 20) in both a state where the dissipation device 400 is adsorbed to the target surface 510 and a state where the dissipation device 400 is standing independently on the placement surface 520, and the user can replace the used container 100 with a new container 100 at an appropriate time.

[0037] Thus, the present invention includes a dissipation device 400 for dissipating a volatile component, the dissipation device 400 comprising a housing 200 for holding a container 100 containing contents 150 containing a volatile component, and a magnet 300 provided in the housing 200 for attracting the dissipation device 400 to a target surface 510. The present invention also provides a container 100 held in a housing 200 of a dissipation device 400 that dissipates volatile components, the container 100 containing a liquid content 150 containing volatile components in a manner that allows the volatile components to be dissipated, and a portion of the container 100 in the width direction is configured to allow the liquid in the container 100 to be seen through, and the container 100 has a larger liquid capacity per unit area than other portions of the container 100 in the width direction.

[0038] Second Embodiment Next, a second embodiment will be described with reference to FIGS. The dissipation device 400 of this modified example differs from the dissipation device 400 of the first embodiment described above in the points described below, but is otherwise configured in the same way as the dissipation device 400 of the first embodiment described above.

[0039] In this embodiment, instead of the first bottom 221 and the second bottom 231, the housing 200 has a stand member 280 that can swing relative to the housing main body 210 between an open state (see Figures 20(a) and 20(b)) and a closed state (see Figures 17 and 18). 20(a) and 20(b), when the stand member 280 is in an open state, the dissipation device 400 can stand on its own without the magnetic force of the magnet 300. When the dissipation device 400 is in a self-standing state, the stand member 280 is grounded to a pair of grounding portions 207 formed at the lower end of the housing main body 210, and the portion at the lower end of the housing main body 210 between the pair of grounding portions 207 forms a drainage hole 208 that drains water that has entered the housing 200 downward. Here, in the case of this embodiment, the state in which the stand member 280 is closed means a state in which the stand member 280 is arranged along the main housing body 210, and the angle formed between the stand member 280 and the main housing body 210 is substantially 0 degrees. Also, the state in which the stand member 280 is open means a state in which the angle formed between the stand member 280 and the main housing body 210 is larger than the angle formed when the stand member 280 is closed. As an example, when the stand member 280 is in an open state, the angle formed between the stand member 280 and the main housing body 210 is preferably 10 degrees or more.

[0040] More specifically, in this embodiment, as shown in FIG. 17 , in the lower half of the annular portion 241, a radially outer portion of the annular portion 241 is a region where the plurality of diffusion holes 243 are not formed, and a storage groove 247 for storing the stand member 280 is formed in this region where the diffusion holes 243 are not formed. The storage groove 247 is recessed forward from the rear surface of the annular portion 241 and is formed in an arc shape (an arc shape that is convex downward) along the circumferential direction of the annular portion 241 in a rear view. As shown in FIG. 19 , the storage groove 247 is displaced forward in a stepped manner toward the radially outward direction, for example. Similarly, a step portion 248 is formed on the inner surface of the annular portion 241 at a portion corresponding to the region where the storage groove 247 is formed, the step portion 248 being displaced backward in a stepped manner toward the radially inward direction.

[0041] 17, stand member 280 is a plate-like member formed in a generally arc-like shape (a downwardly convex arc-like shape) when viewed from behind. Stand member 280 can be housed inside housing groove 247 so that the entire outline of stand member 280 fits inside housing groove 247 when viewed from behind. As shown in FIGS. 18 and 19, when dissipation device 400 is attracted to target surface 510 by the magnetic force of magnet 300, stand member 280 is housed inside housing groove 247 and is in a closed state. Furthermore, the stand member 280 is pivotally supported on the second member 230 so as to be swingable, for example. More specifically, a shaft portion 284 is formed on each of both end portions (both ends in the extension direction) of the stand member 280. The shaft portion 284 extends linearly with the left-right direction as the axial direction. Furthermore, a pair of left and right bearing portions 245 is formed on the annular portion 241 at locations corresponding to both end portions (both ends in the extension direction) of the accommodating groove 247. The shaft portion 284 formed on one end portion of the stand member 280 is inserted into the pair of left and right bearing portions 245 corresponding to one end portion of the accommodating groove 247, and the shaft portion 284 formed on the other end portion of the stand member 280 is also inserted into the pair of left and right bearing portions 245 corresponding to the other end portion of the accommodating groove 247. In this way, the stand member 280 is able to swing around the axis of the shaft portion 284. As shown in Figures 20(a) and 20(b), when the dissipation device 400 is made to stand on its own with the stand member 280 in an open state, the tilt angle of the dissipation device 400 relative to the placing surface 520 can be adjusted by adjusting the swing angle of the stand member 280 relative to the second member 230. Furthermore, a notch-shaped portion 283 that is open downward is formed at the lower end of stand member 280. Notch-shaped portion 283 is formed in a position that partially overlaps with the area where water drainage hole 208 is formed in rear view. Therefore, even when stand member 280 is housed in housing groove 247, water that has entered housing main body 210 can be efficiently drained via water drainage hole 208.

[0042] In the present embodiment, the pair of ground contact portions 207 and drainage hole 208 are formed at the lower end of the second member 230. More specifically, the drainage hole 208, which penetrates the second member 230 from front to rear and is open downward, is formed at the lower end of the second member 230. The left and right portions of the drainage hole 208 at the lower end of the second member 230 form the pair of ground contact portions 207. The drain hole 208 is located, for example, below the protrusion 232 at the lower end of the second member 230. The drain hole 208 connects the inside and outside of the housing 200 to each other.

[0043] Furthermore, in this embodiment, the housing 200 is provided with a cover member 260 that is formed separately from the second member 230. As shown in Figures 16 and 19, the cover member 260 is liquid-tightly fitted into the housing portion 251 while covering the magnet 300 housed in the housing portion 251 from the front. This prevents the magnet 300 from falling out of the housing portion 251 and also prevents water from flowing into the housing portion 251. More specifically, the rear end side of the housing portion 251 is closed by the main surface portion 251a, while the front end side of the housing portion 251 is open toward the front. The magnet 300 is housed inside the housing portion 251 through the opening on the front end side of the housing portion 251. In this embodiment, the portion of the opposing surface 201 that protrudes most toward the target surface 510 is the main surface portion 251 a, and the main surface portion 251 a constitutes the adsorption portion 242 . The cover member 260 is formed in a hollow disk shape, and one axial side of the cover member 260 is closed, while the other axial side is open. With the open side of the cover member 260 positioned on the housing portion 251 side, the entire cover member 260 in the thickness direction is contained within the housing portion 251. Note that the cover member 260 and the housing portion 251 may be joined to each other, for example, by an adhesive (not shown). The inner diameter of the accommodating portion 251 is set, for example, to a dimension that is approximately equal to or slightly larger than the outer diameter of the cover member 260. The inner diameter of the cover member 260 is set, for example, to a dimension that is approximately equal to or slightly larger than the outer diameter of the magnet 300. The depth dimension of the accommodating portion 251 is set, for example, to a dimension that is approximately equal to or slightly larger than the thickness dimension of the cover member 260. The depth dimension of the cover member 260 is set, for example, to a dimension that is approximately equal to or slightly smaller than the thickness dimension of the magnet 300. With this configuration, the cover member 260 can be fitted well inside the accommodation portion 251, and the magnet 300 can be accommodated between the cover member 260 and the accommodation portion 251. More specifically, in the case of this embodiment, the outer peripheral surface of the cover member 260 is in circumferential contact with the inner peripheral surface of the accommodation portion 251. In addition, the surface of the cover member 260 opposite to the magnet 300 side (front surface) is approximately flush with the inner surface of the annular portion 241.

[0044] 19, in this embodiment, the protrusion 232 that presses the film 90 toward the main body case 10 is curved, for example, in a convex arc shape toward the main body case 10 (first member 220). The protrusion 232 extends vertically from the lower end of the annular portion 241 toward the center of the annular portion 241, and divides the storage groove 247 into two equal parts, left and right, in rear view. The width dimension of the protrusion 232 is approximately constant regardless of the position in the extension direction. The protruding height of the lower end of the protrusion 232 becomes slightly smaller downward. 21(a), a plurality of upright plate portions 244 that stand upright toward the front are formed on the inner surface of the upper half of the annular portion 241. The plate surface of each of the plurality of (e.g., six) upright plate portions 244 is arranged facing the radial direction of the annular portion 241. The plurality of upright plate portions 244 extend linearly from the outer circumferential edge to the inner circumferential edge of the annular portion 241. In the upper half of the annular portion 241, each of the plurality of upright plate portions 244 is arranged between adjacent diffusion holes 243 in the circumferential direction of the annular portion 241. With this configuration, the structural strength of the annular portion 241 and, ultimately, the housing main body 210 can be more sufficiently ensured. Furthermore, as shown in FIG. 5 and other figures, the pair of left and right protrusions 257 protrude upward from the upper end of the second circumferential wall portion 241b in directions approaching each other, for example.

[0045] <Modification> Next, a modification of the second embodiment will be described with reference to FIGS. The dissipation device 400 of this modified example differs from the dissipation device 400 of the first and second embodiments described above in the points described below, but is otherwise configured in the same way as the dissipation device 400 of the first and second embodiments described above.

[0046] In the above-described first and second embodiments, an example was described in which a gap between the diffusion hole 243 and the target surface 510 is secured by the portion (adsorption portion 242) on the opposing surface 201 of the housing 200 that protrudes most toward the target surface 510. However, the present invention is not limited to this example, and for example, in the dissipation device 400, the magnet 300 may be the part that protrudes most toward the target surface 510, and the thickness of the magnet 300 may be configured to ensure a gap between the opposing surface 201 and the target surface 510. Even with this configuration, as shown in Figure 23, when the dissipation device 400 is adsorbed to the target surface 510, the volatile components of the contents 150 can be sufficiently dissipated to the outside through the dissipation holes 243 formed in the opposing surface 201. More specifically, in this modified example, magnet 300 is joined to the center of the back surface of housing 200 via, for example, an adhesive (not shown). As an example, a portion of magnet 300 excluding the joint portion with housing 200 (the main surface of magnet 300 facing housing 200) is exposed to the outside of housing 200. In this modification, if magnet 300 is a neodymium magnet, it is preferable that the outer diameter of magnet 300 is 5 mm or more and 15 mm or less, and the thickness of magnet 300 is 1 mm or more and 3 mm or less. Furthermore, if magnet 300 is an anisotropic ferrite magnet, it is preferable that the outer diameter of magnet 300 is 20 mm or more and 35 mm or less, and the thickness of magnet 300 is 1 mm or more and 5 mm or less. With this configuration, the thickness of the magnet 300 ensures a sufficient gap between the opposing surface 201 (and thus the multiple diffusion holes 243) and the target surface 510, while allowing the diffusion device 400 to be stably adsorbed to the target surface 510.

[0047] In addition, in the above-mentioned embodiment, an example was described in which each of the multiple diffusion holes 243 extends linearly in the radial direction of the annular portion 241, but in the case of this modified example, as shown in Figure 22, each of the multiple diffusion holes 243 is formed in a circular shape when viewed from behind. More specifically, in this embodiment, the multiple diffusion holes 243 are arranged at equal intervals in both the radial and circumferential directions of the annular portion 241. For example, the inner diameter of the multiple diffusion holes 243 located radially outward is set to be larger than the inner diameter of the diffusion holes 243 located radially inward. Even with this configuration, it is possible to achieve good structural strength for the second member 230, while ensuring a sufficient total value of the opening area of ​​the diffusion holes 243 (ie, the exposed area of ​​the film 90).

[0048] The present invention is not limited to the above-described embodiments and modifications, but includes various modifications and improvements as long as the object of the present invention is achieved.

[0049] Furthermore, the various components of the dissipation device 400 do not need to be independent entities, and it is acceptable for multiple components to be formed as a single member, for one component to be formed from multiple members, for one component to be part of another component, or for part of one component to overlap with part of another component, etc. [Explanation of symbols]
