Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, in a house, windows and entrances are not always open. Depending on the user's life cycle, for example, during daytime hours due to reasons such as going out, windows and entrances may not be open, and during that time period, there may be no risk of invasion by flying pests.

[0007] The pesticide volatilization device disclosed in Patent Document 1 does not take into account that there may be times when it is not necessary to prevent the entry of flying insects depending on the user's lifestyle. Once use begins, the device continues to volatilize, releasing the volatilizing agent to the outside through the volatilization holes in the inner case and the window holes in the outer case. It is not possible to switch to a non-volatilization state where the volatilizing agent is not released, resulting in the continuous and wasteful release of the volatilizing agent.

[0008] This invention has been made in view of the above-mentioned problems, and aims to provide a drug volatilization device that can easily switch between a volatilization state and a non-volatilization state. [Means for solving the problem]

[0009] The characteristic configuration of the drug volatilization apparatus according to the present invention, which solves the above problems, is as follows: A drug volatilization apparatus comprising a drug volatilizer for volatilizing a volatile drug, a container for containing the drug volatilizer, and a support for the container, The container has a volatilization opening that connects the inside and outside of the container. The support has a storage space capable of accommodating at least a portion of the container, The device is configured to allow switching between a volatilization state, in which the container is placed upright on the support so that at least a portion of the volatilization opening is exposed from the storage space, and a non-volatilization state, in which the container is changed from an upright position to an inverted position so that the volatilization opening is contained within the storage space.

[0010] With this configuration of pesticide volatilization device, the volatilization state is achieved by placing the container on the support in an upright position so that at least a portion of the volatilization opening provided in the container is exposed from the storage space of the support. On the other hand, the non-volatilization state is achieved by changing the container from an upright position to an inverted position so that the volatilization opening is contained within the storage space. In this way, the volatilization state and the non-volatilization state can be easily switched by changing the position of the container between an upright position and an inverted position. As a result, during times when it is not necessary to prevent the invasion of flying insects, the pesticide volatilization device can be set to the non-volatilization state, thereby reducing the wasteful consumption of volatile pesticides.

[0011] In the drug volatilization device according to the present invention, It is preferable to have a closing part that closes the volatilization opening when the state is not volatilized.

[0012] With this configuration of drug volatilization device, when the device is not volatilizing, the volatilization opening of the container is sealed by the occlusion section, which prevents volatile drugs from leaking between the container and the support, thus reducing the wasteful consumption of volatile drugs.

[0013] In the drug volatilization device according to the present invention, It is preferable that, when the container is in the non-volatile state, the upper end of the inverted container protrudes from the support.

[0014] With this configuration of drug volatilization device, when in a non-volatilization state, the user can more easily switch from a non-volatilization state to a volatilization state by placing their fingers on the upper end of the inverted container protruding from the support and operating it.

[0015] In the drug volatilization device according to the present invention, Preferably, the support has a recess formed to be continuous with the housing space.

[0016] According to the chemical agent volatilization device of this configuration, when in the non-volatile state, by operating with fingers on the container in an inverted posture from the recess formed in the support so as to be continuous with the accommodation space, the switching from the non-volatile state to the volatile state can be performed more easily.

[0017] In the chemical agent volatilization device according to the present invention, When in the non-volatile state, it is preferable that the gripping portion is provided on the container so as to be exposed.

[0018] According to the chemical agent volatilization device of this configuration, when in the non-volatile state, by operating with fingers on the exposed gripping portion, the switching from the non-volatile state to the volatile state can be performed more easily.

[0019] In the chemical agent volatilization device according to the present invention, It is preferable that the support has a seating portion on which the bottom of the container in a upright posture is seated when in the volatile state.

[0020] According to the chemical agent volatilization device of this configuration, when in the volatile state, since the bottom of the container in a upright posture is seated on the seating portion, the seating of the container on the support is improved, and the container can be reliably placed on the support.

[0021] In the chemical agent volatilization device according to the present invention, It is preferable to include seating stabilization means for stabilizing the state in which the container is seated on the seating portion.

[0022] According to the chemical agent volatilization device of this configuration, even when vibration or the like acts on the container, the state in which the container is placed on the support in a upright posture can be stably maintained by the seating stabilization means.

[Figure 9] Figure 9 is an explanatory diagram of a drug volatilization device according to another embodiment 4. [Modes for carrying out the invention]

[0024] The present invention will be described below with reference to the drawings. However, the present invention is not intended to be limited to the embodiments and configurations described below or shown in the drawings.

[0025] [First Embodiment] <Overall Structure> Figure 1 is an external perspective view of a drug volatilization device 1 according to one embodiment of the present invention. Figure 1(a) shows the volatilization state, and Figure 1(b) shows the non-volatilization state. The drug volatilization device 1 shown in Figures 1(a) and (b) is a freestanding volatilization device suitable for use in rooms, entrances, etc. This drug volatilization device 1 comprises a drug volatilizer 2 for volatilizing volatile drugs, a container 3 for housing the drug volatilizer 2, and a support 4 for supporting the container 3. The container 3 and support 4 can be manufactured, for example, using resin as the material by known resin molding methods such as injection molding, but are not limited to this. Furthermore, the usage form of the drug volatilization device 1 is not limited to this freestanding type, and various types can be adopted, for example, a clip-type, a hanging type using a strap, an adsorption type using a magnet or suction cup, or an anchor type using hook-and-loop fastener.

[0026] <Volatile pesticides> Volatile agents are not particularly limited as long as they are volatile, regardless of the degree of volatility, and can be used individually or in combination with other insecticides, fragrances, deodorizers, fungicides, antibacterial agents, etc. For example, when used to exterminate or repel flying insects such as mosquitoes, midges, and drain flies, pyrethroid compounds are preferred as volatile agents, and in particular, room-temperature volatile pyrethroid compounds such as metofluthrin, profluthrin, empenthrin, and transfluthrin, which have high volatility and control effects against flying insects, are preferred. Various optical or geometric isomers exist for these volatile pyrethroid compounds, and any isomer can be used. In addition, various additives containing materials that act by aeration, such as activated carbon, can be used, or they can be used in combination with known poorly volatile agents, etc.

[0027] Examples of usable fragrances include aromatic components such as orange oil, lemon oil, lavender oil, peppermint oil, eucalyptus oil, lemon eucalyptus oil, citronella oil, lime oil, yuzu oil, jasmine oil, cypress oil, green tea essential oil, peppermint oil, menthol, menthyl acetate, limonene, α-pinene, linalool, geraniol, phenylethyl alcohol, amyl cinnamic aldehyde, cumin aldehyde, terpineol, and benzyl acetate, as well as fragrance components containing green leaf alcohol or green leaf aldehyde, known as "green scents." These fragrances can be used individually or in combination.

[0028] Examples of usable deodorizers include plant extracts such as green tea extract and persimmon extract, as well as cypress oil, hinoki oil, bamboo extract, mugwort extract, tung oil, and pyruvate esters such as ethyl pyruvate and phenylethyl pyruvate. These deodorizers can be used individually or in combination.

[0029] Examples of usable fungicides include 2-octyl-4-isothiazolin-3-one, 5-chloro-2-methyl-4-isothiazolin-3-one, 3-methyl-4-isopropylphenol, p-chloro-m-xylenol, o-phenylphenol, N-(fluorodichloromethylthio)-phthalimide, hinokitiol, thymol, tetrahydrolinalool, and carvacrol. These fungicides can be used individually or in combination.

[0030] Examples of usable antimicrobial agents include hinokitiol, tetrahydrolinalool, eugenol, citronellal, allyl isothiocyanate, carvone, pinene, terpene alcohols, 3-methyl-4-isopropylphenol, thymol, and carvacrol. These antimicrobial agents can be used individually or in combination.

[0031] <Volatile chemicals> As the volatile agent 2, for example, a structure that holds a volatile agent in a volatile state by impregnation or kneading can be used. Examples of materials for the volatile agent 2 include paper, pulp, natural fibers, synthetic fibers, resin bodies, resin sheets, inorganic or organic porous bodies, gel-like bodies, etc. As a method of holding the agent in the volatile agent 2, impregnating a resin sheet with the agent is simple, but it is preferable to use a resin into which the volatile agent has been kneaded, as this makes it easier to control the sustained release of the volatile agent during the period of use, stabilizes the amount of agent volatilization, and suppresses the runoff of the agent due to moisture such as condensation, but it is not particularly limited. Examples of resins for the resin body and resin sheet include polyethylene, polypropylene, polyvinyl alcohol, polyvinyl acetate, polybutadiene, polyisoprene, ethylene-vinyl acetate copolymer, ethylene-methyl methacrylate copolymer, styrene-butadiene copolymer, etc. The form of the volatile agent 2 is not particularly limited, such as sheet-like, granular, or three-dimensional, but from the viewpoint of improving the volatilization efficiency of volatile agents, for example, a honeycomb structure, a perforated structure, or a planar or three-dimensional mesh structure can be adopted.

[0032] <Container> Figure 2 is a diagram illustrating the structure of the container 3 of the drug volatilization device 1 of this embodiment. Figure 2(a) is a front view, Figure 2(b) is a right side view, and Figure 2(c) is a top view. The back is the same as the front, and the left side is the same as the right side. In the drug volatilization device 1 of this embodiment, a triangular trapezoidal container 3 is used when in an upright position. That is, as shown in Figures 2(a) to (c), the container 3 has a front portion 11 formed in the shape of an equilateral triangle when in an upright position, a back portion 12 formed in the shape of an equilateral triangle that faces the front portion 11 at a predetermined distance in the front-rear direction, and a triangular cylindrical outer surface portion 13 that extends to connect the outer edges of the front portion 11 and the back portion 12.

[0033] <Volatilization opening> As shown in Figure 2(a), the container 3 has a vaporization opening 20 that connects the inside and outside of the container 3. The vaporization opening 20 includes a plurality of front vaporization openings 20a to 20f (six in this example) formed on the front portion 11, and a plurality of rear vaporization openings 20a to 20f (six in this example) formed on the rear portion 12 (not shown). The front vaporization openings 20a to 20f and the rear vaporization openings 20a to 20f consist of a plurality of rectangular slits in which the horizontal length gradually decreases as you move from the bottom edge toward the apex angle on the front portion 11 and the rear portion 12 when the container 3 is in the upright position shown in Figure 2(a), and are formed at a predetermined pitch from the bottom edge toward the apex angle on the front portion 11 and the rear portion 12.

[0034] In this embodiment, the container 3 is divided in the front-to-back direction, with the front portion 11 and the rear portion 12 positioned accordingly. That is, it is divided into a front container portion 3a, which constitutes the front half, and a rear container portion 3b, which constitutes the rear half (lines indicating the division position are not shown). The container is assembled by locking the two container portions 3a and 3b together with the volatile drug 2 sandwiched between them using known locking means (not shown).

[0035] <Support> Figure 3 is an explanatory diagram (1) of the structure of the support body 4 of the drug volatilization device 1 of this embodiment. Figure 3(a) is a front view, Figure 3(b) is a right side view, and Figure 3(c) is a top view. The back is the same as the front, and the left side is the same as the right side. As shown in Figures 3(a) to (c), the support body 4 has a rectangular bottom portion 31, a top portion 32 positioned above the bottom portion 31, an inverted trapezoidal front outer wall portion 33 and a rear outer wall portion 34 in the front-to-back direction, and a trapezoidal left outer wall portion 35 and a right outer wall portion 36 in the left-to-right direction. Here, the top portion 32 is formed as a rectangular ring that is relatively long in the left-to-right direction overall, having an opening 32a that is opened so as to be relatively long in the left-to-right direction in the portion including the center.

[0036] In the support 4, the outer edges of the bottom portion 31 and the outer edges of the top portion 32 are connected by the front outer wall portion 33, the rear outer wall portion 34, the left outer wall portion 35, and the right outer wall portion 36, and adjacent outer wall portions 33,35;35,34;34,36;36,33 in these outer wall portions 33 to 36 are integrally joined together.

[0037] Figure 4 is a diagram (2) illustrating the structure of the support body 4 of the drug volatilization device 1 of this embodiment. Figure 4(a) is a cross-sectional view taken along the arrow AA in Figure 3(a), Figure 4(b) is a cross-sectional view taken along the arrow BB in Figure 3(c), Figure 4(c) is a cross-sectional view taken along the arrow CC in Figure 3(c), and Figure 4(d) is a cross-sectional view taken along the arrow DD in Figure 3(c). As shown in Figures 4(a) to (d), the support body 4 further has an inverted equilateral triangle-shaped front inner wall portion 41 and a rear inner wall portion 42 when viewed in the front-to-back direction, and a rectangular left inner wall portion 43 and a right inner wall portion 44 when viewed in the left-to-right direction. In the support 4, the front inner wall portion 41, the rear inner wall portion 42, the left inner wall portion 43, and the right inner wall portion 44 are integrally joined to the inner periphery around the opening 32a of the top surface portion 32, and adjacent inner wall portions 41,43;43,42;42,44;44,41 in these inner wall portions 41-44 are integrally joined to each other. Furthermore, in the support 4, the lower ends of the left inner wall portion 43 and the right inner wall portion 44 that abut against each other are integrally joined to the bottom surface portion 31 together with the sharply shaped lower ends of the front inner wall portion 41 and the rear inner wall portion 42.

[0038] <Storage space> The support 4 has an inverted triangular trapezoidal storage space 50 that opens upward. The storage space 50 is partitioned by the front inner wall 41, the rear inner wall 42, the left inner wall 43, and the right inner wall 44, and can accommodate most of the container 3, excluding the upper end of the container 3 which is inverted triangular trapezoidal when in an inverted position.

[0039] As shown in Figure 3(c), the size of the upper opening of the storage space 50 is determined by the size of the rectangular opening 32a, which is relatively long in the left-right direction of the top surface portion 32, which is formed in a rectangular ring shape. Here, as shown in Figures 2(a) and (b), in the container 3, the left-right width of the bottom when it is in an upright position is defined as W1 (see Figure 2(a)), and the constant front-rear width from the bottom to the top (from the bottom to the top when it is in an inverted position) is defined as W2 (see Figure 2(b)). On the other hand, as shown in Figure 3(c), in the storage space 50, the left-right width is defined as W 11 And the front-to-back width is W 12 Let's assume that in this case, W1 > W 11 W2 <W 12 W1, W2, W 11 and W 12 Each of the dimensions is set. By setting it in this way, the left and right ends of the bottom of the upright container 3 can be seated on the left and right edges of the opening 32a of the top surface 32, and the left and right edges of the opening 32a of the top surface 32 become the seating portion 55 on which the bottom of the upright container 3 is seated. Then, by seating the upright container 3 on the seating portion 55 of the top surface 32 of the support 4 so as to close the upper opening of the storage space 50, that is, so as to close the opening 32a of the top surface 32, the container 3 sits well on the support 4 and the container 3 can be securely placed on the support 4. Also, as described above, W1, W2, W 11 and W 12 By setting the dimensions of each component, the inverted container 3 can be accommodated in the storage space 50 (excluding the upper end of the inverted container 3).

[0040] In this embodiment, the support 4 shown in Figures 3(a) to 3(c) is shown as an example of being constructed by integral molding. However, it may also be possible to divide the support 4 into two halves in the front-to-back direction where the front outer wall portion 33 and the rear outer wall portion 34 are arranged, that is, into a front support portion 4a which constitutes the front half and a rear support portion 4b which constitutes the rear half (lines indicating the division position are not shown), and to assemble the support by locking the two support portions 4a and 4b together using known locking means.

[0041] Figure 5 is a diagram showing the state of the drug volatilization device 1 of this embodiment, with changes in the orientation of the container 3 relative to the support 4. Figure 5(a) shows the state in which the container 3 is placed on the support 4 in an upright position. Figure 5(b) shows the state in which the container 3 is in the process of changing from an upright position to an inverted position (and from an inverted position to an upright position). Figure 5(c) shows the state in which the volatilization opening 20 of the container 3 is completely housed in the housing space 50 of the support 4 in an inverted position, and most of the container 3, excluding the upper end of the inverted container 3, is housed in the housing space 50 of the support 4.

[0042] In the drug volatilization device 1 configured as described above, the state shown in Figure 5(a) is a volatilization state in which the container 3 is placed upright on the support 4, with both left and right ends of the bottom of the upright container 3 seated on the seating portion 55 of the top portion 32 (see Figure 3(c)), so that all of the volatilization openings 20 provided in the container 3 are exposed from the storage space 50. In this volatilization state, the inside and outside of the container 3 are in communication through the volatilization openings 20, and the volatile drug is volatilized according to the size of the area (ventilation area) of the volatilization openings 20. In this example, since all of the volatilization openings 20 are completely exposed from the storage space 50, the volatile drug is volatilized to the maximum extent.

[0043] As shown in Figures 5(b) to (c), the container 3 is turned upside down from an upright position to an inverted position, and the inverted container 3 is fitted into the storage space 50 starting from its pointed lower end. As a result, with the upper end of the inverted container 3 protruding from the support 4, most of the inverted container 3 is housed in the storage space 50, and all of the volatilization opening 20 of the inverted container 3 is housed in the storage space 50.

[0044] The state shown in Figure 5(c) is a non-volatilization state in which the volatilization opening 20 provided in the container 3 is completely contained within the storage space 50 of the support 4. In this non-volatilization state, the front inner wall portion 41 of the support 4 is in contact with or close to the front portion 11 of the container 3 where the volatilization opening 20 is formed, and the rear inner wall portion 42 of the support 4 is in contact with or close to the rear portion 12 of the container 3 where the volatilization opening 20 is formed. As a result, the flow of volatile chemicals attempting to volatilize from the inside of the container 3 through the volatilization opening 20 to the outside is blocked by the front inner wall portion 41 and the rear inner wall portion 42. In this way, the front inner wall portion 41 and the rear inner wall portion 42 function as occluding portions that block the volatilization opening 20 when in the non-volatilization state, preventing leakage of volatile chemicals from between the container 3 and the support 4, and reducing the wasteful consumption of volatile chemicals. The front inner wall portion 41 and the rear inner wall portion 42 correspond to the "closed portion" of the present invention.

[0045] When switching from the non-volatilization state shown in Figure 5(c) to the volatilization state (maximum volatilization state) shown in Figure 5(a), the upper end of the inverted container 3 protruding from the support 4 is grasped with fingers, and the container is removed from the storage space 50 as shown in Figure 5(b). Then, the container 3 is turned over from the inverted position to an upright position, and both left and right ends of the bottom of the upright container 3 are seated on the seating portion 55 of the top surface 32 (see Figure 3(c)), so that the container 3 is placed on the support 4 in an upright position and enters the volatilization state. In this way, by changing the position of the container 3 between the upright and inverted positions, it is possible to easily switch between the volatilization state shown in Figure 5(a) and the non-volatilization state shown in Figure 5(c). As a result, during times when it is not necessary to prevent the intrusion of flying insects, or during times when fragrance or deodorization is not necessary, the pesticide volatilization device 1 can be set to the non-volatilization state, thereby reducing the wasteful consumption of volatile pesticides.

[0046] The present invention has been described above based on one embodiment, but the present invention is not limited to the configuration described in the above embodiment, and its configuration can be modified as appropriate without departing from the spirit of the invention. Specific alternative embodiments are as follows.

[0047] (Another Embodiment 1) Figure 6 is an explanatory diagram of a drug volatilization device 1A of another embodiment 1. In the drug volatilization device 1A, the support body 4 has a recessed portion 60 formed to be continuous with the storage space 50. That is, on the top surface 32 of the support body 4, a pair of substantially semi-elliptical recessed portions 60 are formed to be continuous with both ends of the longitudinal direction (left-right direction) of the opening 32a of the top surface 32.

[0048] In the drug volatilization device 1A of the other embodiment 1, when the device is in the non-volatilization state shown in Figure 6, the user can operate the inverted container 3 by placing their fingers on it through the pair of recesses 60. This makes it easier to switch from the non-volatilization state to the volatilization state, even when the difference in height between the surface exposed upwards on the outer peripheral surface 13 of the inverted container 3 and the top surface 32 of the support 4 is small, i.e., even when it is difficult to place fingers on the upper end of the inverted container 3.

[0049] (Another Embodiment 2) Figure 7 is an explanatory diagram of the drug volatilization device 1B of another embodiment 2. Figure 7(a) shows an example in which a non-protruding knob 65 is provided on the container 3, and Figure 7(b) shows an example in which a protruding knob 65 is provided on the container 3. As shown in Figures 7(a) and (b), in the drug volatilization device 1B, the knob 65 is provided on the container 3 so as to be exposed when not in a volatilization state. That is, in the example shown in Figure 7(a), on the surface of the outer peripheral surface 13 of the inverted container 3 that is exposed toward the top, a cylindrical knob 65 is formed in the center of the surface by countersinking in an annular shape around the center of the surface. On the other hand, in the example shown in Figure 7(a), on the surface of the outer peripheral surface 13 of the inverted container 3 that is exposed toward the top, a semicircular knob 65 is formed in the front-to-back direction so as to protrude upward in the center of the surface.

[0050] In the drug volatilization device 1B shown in Figures 7(a) and (b), when the device is not volatilizing, the user can operate it by placing their fingers on the upward-facing handle 65 and pinching it. This makes it easier to switch from the non-volatilizing state to the volatilizing state, even when the difference in height between the upward-facing surface of the outer peripheral surface 13 of the inverted container 3 and the top surface 32 of the support 4 is small, i.e., even when it is difficult to place fingers on the upper end of the inverted container 3.

[0051] (Another embodiment 3) Figure 8 is an explanatory diagram of the drug volatilization device 1C of another embodiment 3. Figure 8(a) shows an example in which a rubber packing 70 is used as a seating stabilization means to stabilize the state in which the container 3 is seated on the seating portion 55. Figure 8(b) shows an example in which a stepped portion 75 is provided as the same seating stabilization means. In the examples shown in Figures 8(a) and (b), the peripheral edge extending around the entire circumference of the opening 32a of the top surface portion 32 is made up to be the seating portion 55 on which the bottom of the upright container 3 is seated. By seating the upright container 3 on the seating portion 55 of the top surface portion 32 of the support 4 so as to close the upper opening of the storage space 50, that is, so as to close the opening 32a of the top surface portion 32, the container 3 sits better on the support 4 and the container 3 can be placed on the support 4 more securely. Furthermore, in the examples shown in Figures 8(a) and (b), a base portion 3a is formed on the bottom of the upright container 3, which protrudes in a rectangular shape in plan view so as to be engageable with the seat portion 55. In the example shown in Figure 8(a), a rubber packing 70 is attached to the seat portion 55 of the top surface portion 32 of the support 4 to increase the coefficient of static friction between it and the bottom of the upright container 3, and to increase the degree of adhesion. In this example, an example is shown in which the rubber packing 70 is embedded in the seat portion 55, but an example is also shown in which the rubber packing 70 is attached to the seat portion 55. In addition, in this example, a rubber packing 70 is exemplified as a member that increases the coefficient of static friction between it and the bottom of the upright container 3, but it is not limited to this, and any member that can increase the coefficient of static friction is acceptable. Furthermore, the coefficient of static friction may be increased by processing the surface of the portion of the top surface portion 32 that becomes the seat portion 55 to be rough. On the other hand, in the example shown in Figure 8(b), a stepped portion 75 is formed around the seating portion 55 on the top surface 32 of the support 4, which is capable of engaging with the base portion 3a of the upright container 3 that is seated on the seating portion 55.

[0052] In the drug volatilization device 1C shown in Figure 8(a), the rubber packing 70 embedded in the seating portion 55 increases the coefficient of static friction between the bottom of the upright container 3 and the packing, and also increases the degree of contact. Therefore, even if forces or vibrations that cause the container 3 to move laterally are applied to the support 4, the container 3 can be more stably kept in an upright position on the support 4.

[0053] On the other hand, in the drug volatilization device 1C shown in Figure 8(b), the stepped portion 75 provided around the seating portion 55 restricts the lateral movement of the container 3 relative to the support 4. Therefore, even if forces or vibrations that cause the container 3 to move laterally act on the support 4, the container 3 can be more stably kept in an upright position on the support 4.

[0054] (Another Embodiment 4) Figure 9 is an explanatory diagram of the drug volatilization device 1D of alternative embodiment 4. In the above embodiment and alternative embodiments 1 to 3, an example was shown in which a triangular trapezoidal container 3 was used in an upright position. However, as shown in Figure 9, in the drug volatilization device 1D of alternative embodiment 4, a truncated triangular trapezoidal container 3 is used, which is like the container 3 of the above embodiment and alternative embodiments 1 to 3 with the top cut off in an upright position. In the drug volatilization device 1D of alternative embodiment 4, the support body 4 has an inverted truncated triangular trapezoidal storage space 50 that opens upward. The storage space 50 can accommodate most of the container 3, excluding the upper end of the container 3 which becomes an inverted truncated triangular trapezoidal shape when in an inverted position.

[0055] (Another embodiment 5) The shape of the container 3 in the upright position is not limited to the truncated triangular or truncated triangular truncated shapes exemplified in the above embodiment and other embodiments 1 to 4, but may be, for example, a cone, a triangular pyramid, a square pyramid, a polygonal pyramid with pentagons or more, a truncated frustocone, a truncated triangular frustocone, a truncated square pyramid, or a truncated polygonal pyramid with pentagons or more. In this case, the shape of the storage space 50 can be an inverted cone, an inverted triangular pyramid, an inverted square pyramid, an inverted polygonal pyramid with pentagons or more, an inverted truncated frustocone, an inverted truncated triangular frustocone, an inverted truncated square pyramid, or an inverted truncated polygonal pyramid with pentagons or more.

[0056] (Another embodiment 6) In the above embodiment of the drug volatilization device 1, an example was shown in which a triangular trapezoidal container 3 having a constant front-to-back width W2 from the bottom to the top when in an upright position is used. However, the device is not limited to this, and a container 3 may be used in which the front part 11 and the back part 12 are inclined such that the distance between them gradually decreases as one moves from the bottom to the top when in an upright position, that is, a container 3 in which the front-to-back width gradually decreases from W2 from the bottom to the top when in an upright position. In this case, the shape of the bottom of the container 3 in an upright position is similar to the shape of the opening 32a of the top surface 32, and the size of the bottom of the container 3 in an upright position is set to be larger than the size of the opening 32a of the top surface 32. This makes it possible to seat the bottom of the container 3 in an upright position on the peripheral edge that extends around the entire circumference of the opening 32a of the top surface 32, and this peripheral edge becomes a seating portion corresponding to the seating portion 55 in the above embodiment. By doing so, the bottom of the upright container 3 is seated on the seating portion formed around the entire circumference of the opening 32a of the top surface portion 32, so as to close the upper opening of the storage space 50, that is, so as to close the opening 32a of the top surface portion 32, the container 3 sits better on the support 4 and can be placed on the support 4 more securely. It goes without saying that the front inner wall portion 41 of the support 4 is in contact with or close to the inclined front portion 11 as described above, and the rear inner wall portion 42 of the support 4 is in contact with or close to the inclined rear portion 12 as described above, so as to be configured, the front inner wall portion 41 and the rear inner wall portion 42 are inclined.

[0057] (Another embodiment 7) In the above embodiments, as well as in other embodiments 1 to 6, examples of stationary volatilization devices, namely pesticide volatilization devices 1, 1A, 1B, 1C, and 1D, were shown. However, it is also possible to use the pesticide volatilization device while it is attached to an object. For example, the pesticide volatilization device can be attached to the wall of a room or suspended from the ceiling. In other words, the pesticide volatilization device may be configured to be attached to an object such as the wall or ceiling of a room. With such a mounting type of pesticide volatilization device, it is possible to use the pesticide volatilization device in the processing space even when there is insufficient space on the floor or a stand to place the pesticide volatilization device on.

[0058] The attachment-type chemical vaporization device can be used by attaching it to any component inside a vehicle, for example, and is particularly useful when attached to the sun visor installed inside the vehicle. In other words, the target for attachment of the chemical vaporization device may be the sun visor installed inside the vehicle. In its normal non-use state, the sun visor is located directly below the roof, behind the vehicle's windshield. Therefore, for example, a clip (which may be hook-shaped) can be provided on the support 4, and the chemical vaporization device can be attached by clipping the clip to the sun visor. In this case, the chemical vaporization device can be used as an air freshener or insect repellent for automobiles.

[0059] Thus, mounting the chemical vaporizer on the sun visor, compared to mounting it on the dashboard or elsewhere, prevents direct sunlight from hitting it. This reduces the effects of ultraviolet rays and high temperatures, thereby suppressing the deterioration of the materials constituting the chemical vaporizer and the chemicals contained within it. Furthermore, it also suppresses excessive vaporization of the chemicals. Moreover, it obstructs the driver's view less than mounting it on the dashboard, offering significant safety advantages. [Industrial applicability]

[0060] The chemical volatilization device of the present invention can be used not only as a device for volatilizing fragrances and deodorizers, but also particularly effectively for the purpose of exterminating or repelling flying insects such as mosquitoes, midges, and drain flies, as well as mites and crawling insects.
