Description

[Technical Field]

[0001] The present invention relates to a drug volatilization device comprising a drug volatilizer that volatilizes a volatile drug, an inner container that contains the drug volatilizer, and an outer container that is disposed outside the inner container. [Background technology]

[0002] For example, chemical volatilization devices are used to volatilize volatile chemicals such as air fresheners, deodorants, repellents, and insect repellents (see Patent Document 1).

[0003] Patent Document 1 discloses a chemical volatilization device (sliding type air freshener container) that is configured such that an inner box is inserted into an outer box, and when the inner box is pulled out from the outer box by a predetermined distance, holes formed in the inner box and holes formed in the outer box overlap, causing the air freshener stored inside the inner box to volatilize into the outside air.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-258116 Summary of the Invention [Problem to be solved by the invention]

[0005] In the drug volatilization device described in Patent Document 1, when pulling out the inner box from the outer box, for example, the outer box is held with one hand, and the upper and lower panels of the inner box exposed from the notches formed in the center of the front edges of the upper and lower panels of the outer box are grasped with the other hand, and the inner box is moved relative to the outer box so as to be pulled out. Thus, in the drug volatilization device described in Patent Document 1, the inner box (inner container) cannot be moved relative to the outer box (outer container) without using both hands, and it can be said that there is room for improvement in the operability when moving the inner box relative to the outer box.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a drug volatilization device that is configured to be able to switch between a volatilization state and a non-volatilization state by moving the inner container relative to the outer container, and that has improved operability when moving the inner container relative to the outer container. [Means for solving the problem]

[0007] The characteristic configuration of the chemical volatilization device according to the present invention to solve the above problem is as follows: A drug volatilization device comprising a drug volatilizer that volatilizes a volatile drug, an inner container that contains the drug volatilizer, and an outer container that is disposed outside the inner container, The inner container has a push button portion to which a pushing force is applied and an inner opening portion, the outer container has an outer opening corresponding to the inner opening; The inner container is configured to be movable relative to the outer container along a direction in which the pressing force applied to the push button portion acts, When the inner container is moved relative to the outer container, the inner opening and the outer opening are at least partially overlapping, thereby allowing communication between the inside of the inner container and the outside of the outer container, and the inner opening and the outer opening are not completely overlapping, thereby allowing switching between a volatilization state and a non-volatilization state, wherein the inside of the inner container and the outside of the outer container are cut off from each other.

[0008] According to this configuration of drug volatilization device, the inner container has a push button portion to which a pressing force is applied, and the inner container is configured to be movable relative to the outer container in the direction of the pressing force applied to the push button portion. Moving the inner container relative to the outer container switches between a volatilization state in which the inner opening and the outer opening are at least partially overlapping, thereby communicating the inside of the inner container with the outside of the outer container, and a non-volatilization state in which the inner opening and the outer opening are not completely overlapping, thereby blocking the inside of the inner container from the outside of the outer container. In this way, in a drug volatilization device that can switch between a volatilization state and a non-volatilization state by moving the inner container relative to the outer container, for example, by holding the outer container with the remaining four fingers excluding the index finger and applying a pressing force to the push button portion with the index finger, the operation of moving the inner container relative to the outer container can be performed with one hand. Therefore, the operability of moving the inner container relative to the outer container can be improved compared to conventional drug volatilization devices (Patent Document 1), which required the use of both hands to move the inner container (inner box) relative to the outer container (outer box).

[0009] In the chemical volatilization device according to the present invention, The push button portion includes: a first push button portion that is hidden inside the outer container in the volatilizing state and that protrudes outside the outer container in the non-volatilizing state; a second push button portion that protrudes outside the outer container in the volatilizing state and is hidden inside the outer container in the non-volatilizing state; It is preferred that the compound contains:

[0010] According to the drug volatilization device of this configuration, when the drug is in a non-volatilization state, applying a pressing force to the first push button portion that protrudes from the outer container can switch the drug from the non-volatilization state to the volatilization state. Conversely, when the drug is in a volatilization state, applying a pressing force to the second push button portion that protrudes from the outer container can switch the drug from the volatilization state to the non-volatilization state. In this way, the drug volatilization state and the non-volatilization state can be easily switched by applying a pressing force to the first push button portion and the second push button portion.

[0011] In the chemical volatilization device according to the present invention, It is preferable to provide a locking means for locking the inner container and the outer container at a relative position where the inner container and the outer container are in the volatilizing state and / or the non-volatilizing state.

[0012] With this configuration of drug volatilization device, the inner container and the outer container are locked by a locking means at the relative positions where they are in a volatilized and / or non-volatilized state, so that the volatilized and / or non-volatilized state can be maintained stably.

[0013] In the chemical volatilization device according to the present invention, It is preferable that a sealing means be provided to prevent the volatile chemical from leaking from between the inner container and the outer container when the chemical is in the non-volatile state.

[0014] With this configuration of drug volatilization device, when the device is in a non-volatilizing state, the sealing means can prevent leakage of the volatile drug from between the inner container and the outer container, thereby reducing wasteful consumption of the volatile drug.

[0015] In the chemical volatilization device according to the present invention, The outer opening includes an outer lower opening arranged opposite to a mounting surface on which the chemical volatilization device is placed, The inner opening preferably includes an inner lower opening corresponding to the outer lower opening.

[0016] With this configuration of drug volatilization device, the volatile drug from the drug volatilizer is volatilized from the inside of the inner container to the outside of the outer container through the inner opening including the inner bottom opening and the outer opening including the outer bottom opening, thereby further increasing the amount of drug volatilization and further expanding the drug volatilization area.

[0017] In the chemical volatilization device according to the present invention, The outer container preferably has an opening / closing structure that partially opens and closes to allow the inner container to be taken in and out.

[0018] According to the drug volatilization device of this configuration, the outer container has an opening and closing structure in which a portion thereof opens and closes to allow the inner container to be inserted and removed, thereby increasing the airtightness between the inner container and the outer container and allowing the inner container to be easily inserted and removed from the outer container.

[0019] In the chemical volatilization device according to the present invention, It is preferable that the chemical vaporization device is configured to be attachable to an object to be attached.

[0020] With this configuration of drug volatilization device, even in situations where it is difficult to place the drug volatilization device, the drug volatilization device is configured to be attachable to the object to be attached, so it can be used as an attachable type drug volatilization device.

[0021] In the chemical volatilization device according to the present invention, The object to be attached is preferably a sun visor installed in an automobile.

[0022] According to the chemical volatilization device of this configuration, the chemical volatilization device can be attached to the sun visor installed in the car and used, making it possible to use it as a car deodorizer or insect repellent. Furthermore, compared to when it is installed on a dashboard, etc., this type of use prevents direct sunlight from hitting it, thereby reducing the effects of ultraviolet rays and high temperatures. As a result, deterioration of the materials that make up the chemical volatilization device and the chemicals contained in the chemical volatilization device are suppressed, and excessive chemical volatilization can also be suppressed. Moreover, compared to when it is installed on a dashboard, etc., it does not obstruct the driver's view as much, which is a great advantage in terms of safety. [Brief explanation of the drawings]

[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 described below or the configurations shown in the drawings.

[0025] FIG. 1 is an external perspective view of a drug volatilization device 1 according to one embodiment of the present invention in a maximum volatilization state. FIG. 1(a) is an upper perspective view of the drug volatilization device 1 in a maximum volatilization state as seen from the front side. FIG. 1(b) is a lower perspective view of the drug volatilization device 1 in a maximum volatilization state as seen from the back side. FIG. 2 is an external perspective view of a drug volatilization device 1 according to one embodiment of the present invention in a non-volatilization state. FIG. 2(a) is an upper perspective view of the drug volatilization device 1 in a non-volatilization state as seen from the front side. FIG. 2(b) is a lower perspective view of the drug volatilization device 1 in a non-volatilization state as seen from the back side. The drug volatilization device 1 shown in FIGS. 1 and 2 is a freestanding volatilization device suitable for use in a room, entrance, etc. However, the use of the drug volatilization device 1 is not limited to this freestanding type, and various types can be used, such as a clip-type device using a clip, a hanging type device using a strap, an adhesive type device using a magnet or suction cup, and an anchor type device using a hook-and-loop fastener.

[0026] <Overall structure> 1(a) and 1(b), the drug volatilization device 1 includes a drug volatilizer 2 that holds a volatile drug so that it can volatilize, an inner container 3 that houses the drug volatilizer 2, and an outer container 4 that is disposed outside the inner container 3 and houses the inner container 3. In the drug volatilization device 1, the inner container 3 and the outer container 4 form a nested (double-layered) storage container 5. The inner container 3 and the outer container 4 that form the storage container 5 can be made by a known resin molding method such as injection molding using resin as a material, for example, but are not limited to this.

[0027] <Volatile agents> The volatile agent may be an insect repellent, an aromatic, a deodorizer, an antifungal agent, an antibacterial agent, or the like, and may be used alone or in combination, but is not particularly limited thereto. For example, when used for the purpose of exterminating or repelling flying pests such as mosquitoes, midges, and moth flies, it is preferable to use a pyrethroid compound as the volatile agent. In particular, room-temperature volatile pyrethroid compounds such as metofluthrin, profluthrin, empenthrin, and transfluthrin, which have high volatility and high control effect against flying pests, are preferred. Note that these volatile pyrethroid compounds exist as various optical isomers or geometric isomers, and any isomer can be used. Furthermore, various additives can be used, or the compound can be used in combination with known non-volatile agents, etc.

[0028] Examples of aromatic agents include 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 leaf alcohol or leaf aldehyde, known as the "scent of greenery." These aromatic agents can be used alone or in combination.

[0029] Examples of deodorizers include plant extracts such as green tea extract and persimmon extract, as well as hiba oil, cypress oil, bamboo extract, mugwort extract, tung oil, and pyruvic acid esters such as ethyl pyruvate and phenylethyl pyruvate. These deodorizers can be used alone or in combination. Deodorizers made of porous materials such as activated carbon and zeolite can also be used. Furthermore, deodorizers containing metal ions such as silver, copper, and zinc, or titanium oxide photocatalysts, processed into plates, granules, sheets, etc., and carrying a volatile deodorizer can also be used.

[0030] Examples of antifungal agents 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, carvacrol, etc. These antifungal agents can be used alone or in combination.

[0031] Examples of antibacterial agents include hinokitiol, tetrahydrolinalool, eugenol, citronellal, allyl isothiocyanate, carvone, pinene, terpene alcohol, 3-methyl-4-isopropylphenol, thymol, carvacrol, etc. These antibacterial agents can be used alone or in combination.

[0032] <Drug volatilization body> The chemical volatilizer 2 can be, for example, one configured to hold a volatile chemical in a volatilizable manner by impregnation or kneading. Examples of materials for the chemical volatilizer 2 include paper, pulp, natural fibers, synthetic fibers, resin bodies, resin sheets, inorganic and organic porous bodies, and gel-like bodies. While impregnating a resin sheet with the chemical is a simple method for holding the chemical in the chemical volatilizer 2, it is preferable to use a resin kneaded with the volatile chemical because it is easier to control the sustained release of the volatile chemical during use, stabilizes the amount of chemical volatilization, and prevents the chemical from being washed away by moisture such as rain. However, this 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, and styrene-butadiene copolymer. The form of the drug volatilizer 2 is not particularly limited to sheet-like, granular, three-dimensional, etc., but from the viewpoint of improving the volatilization efficiency of the volatile drug, for example, a honeycomb structure, a perforated structure, a flat or three-dimensional mesh structure, etc. can be adopted.

[0033] <Inner container> Fig. 3 is an external perspective view of the inner container 3. Fig. 3(a) is an upper perspective view of the inner container 3 as seen from the front side. Fig. 3(b) is a lower perspective view of the inner container 3 as seen from the rear side. As shown in Figs. 3(a) and 3(b), the inner container 3 has an inner container body 10 and a push button portion 30 to which a pushing force is applied.

[0034] The inner container body 10 comprises an inner front portion 11 constituting the front portion, an inner back portion 12 constituting the back portion, an inner upper surface portion 13 constituting the top surface portion, an inner lower surface portion 14 constituting the bottom surface portion, an inner right surface portion 15 constituting the right surface portion, and an inner left surface portion 16 constituting the left surface portion. In the inner container body 10, adjacent surface portions of the inner front portion 11, inner back portion 12, inner upper surface portion 13, inner lower surface portion 14, inner right surface portion 15, and inner left surface portion 16 are integrally connected to each other and are formed into a rectangular hexahedron shape when viewed from the front that is long in the left-right direction.

[0035] <Inner opening> The inner front portion 11 is provided with a plurality of (three in this example) rectangular inner front openings 21 elongated in the vertical direction, spaced at a predetermined pitch in the left-right direction. The inner back portion 12 is provided with a plurality of (three in this example) rectangular inner back openings 22 elongated in the vertical direction, spaced at a predetermined pitch in the left-right direction so as to correspond to the plurality of inner front portions 21. The inner upper portion 13 is provided with a plurality of (three in this example) rectangular inner upper openings 23 elongated in the left-right direction, spaced at a predetermined pitch in the left-right direction. The inner lower portion 14 is provided with a plurality of (three in this example) rectangular inner lower openings 24 elongated in the left-right direction, spaced at a predetermined pitch in the left-right direction so as to correspond to the plurality of inner upper openings 23. The "inner openings" in this invention include the inner front openings 21, the inner back openings 22, the inner upper openings 23, and the inner lower openings 24. In the following description, these openings 21 to 24 may be collectively referred to as "inner openings 20" as needed.

[0036] <Push button section> The push button portion 30 includes a first push button portion 31 and a second push button portion 32. The first push button portion 31 is provided in the shape of a rectangular block protruding to the right side at the vertical center of the inner right surface portion 15 of the inner container body 10. The first push button portion 31 is configured to protrude from the inner right surface portion 15 by an amount such that it is hidden inside the outer container 4 in the maximum volatilization state (see FIG. 1(a)) and protrudes outside the outer container 4 in the non-volatilization state (see FIG. 2(a)). The second push button portion 32 is provided in the shape of a rectangular block protruding to the left side at the vertical center of the inner left surface portion 16 of the inner container body 10. The second push button portion 32 is configured to protrude from the inner left surface portion 16 by an amount such that it protrudes outside the outer container 4 in the maximum volatilization state (see FIG. 1(b)) and protrudes inside the outer container 4 in the non-volatilization state (see FIG. 2(b)). The shape of the push button 30 is not limited to a rectangular block, but may be, for example, a cylindrical shape, a crescent shape (see FIG. 6), or a wave shape. The first push button 31 and the second push button 32 may each have a different shape or color, and in that case, it is preferable to set the shape and color of each of the first push button 31 and the second push button 32 so that the user can easily recognize the usage state (ON (volatile state) / OFF (non-volatile state)).

[0037] In this embodiment, when the direction in which the inner front portion 11 and the inner back portion 12 are arranged is defined as the front-to-back direction, the inner container 3 can be divided in two in the front-to-back direction, i.e., into a front container portion 3a that constitutes the front half and a back container portion 3b that constitutes the back half (the line indicating the division position is not shown), and is configured to be assembled by sandwiching the drug volatilizer 2 between the two container portions 3a and 3b and locking them together using a known locking means not shown.

[0038] <Outer container> 1(a) and 1(b), the outer container 4 includes an outer front portion 41 constituting the front portion, an outer rear portion 42 constituting the rear portion, an outer upper portion 43 constituting the upper portion, and an outer lower portion 44 constituting the lower portion. In this outer container 4, adjacent surface portions of the outer front portion 41, outer rear portion 42, outer upper portion 43, and outer lower portion 44 are integrally connected to each other to form a rectangular shape in front view that is elongated in the left-right direction and has a hollow portion that is open in the left-right direction. The outer front portion 41, outer rear portion 42, outer upper portion 43, and outer lower portion 44 of the outer container 4 face the inner front portion 11, inner rear portion 12, inner upper portion 13, and inner lower portion 14 of the inner container 3 disposed inside the outer container 4, respectively. In this embodiment, when the direction in which the outer front portion 41 and the outer back portion 42 are arranged is defined as the front-to-back direction, the outer container 4 can be divided in two in the front-to-back direction, i.e., into a front container portion 4a that constitutes the front half and a back container portion 4b that constitutes the back half (the line indicating the division position is not shown), and is configured to be assembled by sandwiching the inner container 3 between the two container portions 4a and 4b so that it can be moved left and right and locking them together using a known locking means not shown.

[0039] <Outside opening> The outer front portion 41 is provided with a plurality of (three in this example) rectangular outer front openings 51 elongated in the vertical direction, spaced at a predetermined pitch in the left-right direction to correspond to the plurality of inner front openings 21. The outer back portion 42 is provided with a plurality of (three in this example) rectangular outer back openings 52 elongated in the vertical direction, spaced at a predetermined pitch in the left-right direction to correspond to the plurality of inner back openings 22. The outer upper portion 43 is provided with a plurality of (three in this example) rectangular outer upper openings 53 elongated in the left-right direction, spaced at a predetermined pitch in the left-right direction to correspond to the plurality of inner upper openings 23. The outer lower portion 44 is provided with a plurality of (three in this example) rectangular outer lower openings 54 elongated in the left-right direction, spaced at a predetermined pitch in the left-right direction to correspond to the plurality of inner lower openings 24. The "outer openings" in this invention include the outer front openings 51, the outer back openings 52, the outer upper openings 53, and the outer lower openings 54. In the following description, these openings 51 to 54 may be collectively referred to as "outer openings 50" as necessary.

[0040] A pair of legs 55 protrude downward from both left and right ends of the outer lower surface portion 44 of the outer container 4. In the drug volatilization device 1 of this embodiment, by providing the pair of protruding legs 55, a lower surface side flow path 56 is formed between the placing surface on which the drug volatilization device 1 is placed and the outer lower surface portion 44, which leads to the outside of the outer container 4 through a plurality of outer lower surface openings 54 arranged opposite the placing surface.

[0041] In the drug volatilization device 1 of this embodiment, the inner container 3 is inserted into the hollow portion of the outer container 4 so that the inner container 3 can move relative to the outer container 4 along the direction (left-right direction) in which the pressing force applied to the first push button portion 31 and the second push button portion 32 acts. When the inner container 3 is moved relative to the outer container 4, the inner opening 20 and the outer opening 50 are at least partially overlapped, thereby allowing the inside of the inner container 3 to communicate with the outside of the outer container 4 (see FIG. 1 for the maximum volatilization state), and the inner opening 20 and the outer opening 50 are not completely overlapped, thereby allowing the inside of the inner container 3 to be switched to a non-volatilization state (see FIG. 2) in which the inside of the inner container 3 is cut off from the outside of the outer container 4.

[0042] <Latching means> 4A and 4B are explanatory diagrams of the internal structure of the drug volatilization device 1 in the maximum volatilization state and the non-volatilization state. FIG. 4A shows the internal structure of the drug volatilization device 1 in the maximum volatilization state, and is a cross-sectional view taken along the line AA in FIG. 1A. FIG. 4B shows the internal structure of the drug volatilization device 1 in the non-volatilization state, and is a cross-sectional view taken along the line BB in FIG. 2A. As shown in FIGS. 4A and 4B, a pair of first locking protrusions 61 and a pair of second locking protrusions 62 are provided on the inner upper surface 13 and the inner lower surface 14 of the inner container 3, respectively, in a vertical direction, at a predetermined interval in the direction of relative movement of the inner container 3 with respect to the outer container 4 (left-right direction). As shown in FIG. 4A, a pair of first locking recesses 71 are formed on the outer upper surface 43 and the outer lower surface 44 of the outer container 4, which engage with the pair of first locking protrusions 61 at the relative positions of the inner container 3 and the outer container 4 when the drug volatilization device 1 is in the maximum volatilization state. As shown in Figure 4(b), a pair of second locking recesses 72 that engage with a pair of second locking protrusions 62 are formed on the outer upper surface portion 43 and the outer lower surface portion 44 of the outer container 4 at the relative positions of the inner container 3 and the outer container 4 where the drug volatilization device 1 is in a non-volatilization state. The configuration including the first locking protrusions 61, first locking recesses 71, second locking protrusions 62, and second locking recesses 72 corresponds to the "locking means" of the present invention.

[0043] <Sealing method> 4(a) and (b), a pair of outward flanges 65 are formed on both left and right ends of the inner container 3 so as to sandwich the inner opening 20 (inner front opening 21, inner back opening 22, inner upper opening 23, and inner lower opening 24) in the left-right direction, and are continuous in an annular shape with the outer peripheral surface of the inner container body 10 (inner front portion 11, inner upper surface 13, inner back portion 12, and inner lower surface 14: see FIG. 3). As shown in FIG. 4(b), the outer container 4 has a pair of inward flanges 75 adjacent to the pair of outward flanges 65, which are continuous in an annular shape over all the surface portions of the outer front portion 41, outer upper surface 43, outer back portion 42, and outer lower surface 44 at the relative positions of the inner container 3 and the outer container 4 where the drug volatilization device 1 is in a non-volatilization state. In this way, a winding path is formed between the inner container 3 and the outer container 4 by the pair of outward flange portions 65 and the pair of inward flange portions 75 that are close together when the chemical volatilization device 1 is in the non-volatilization state shown in Figure 4(b). This allows the pair of outward flange portions 65 and the pair of inward flange portions 75 to function as a labyrinth seal 80 (corresponding to the "sealing means" of the present invention).

[0044] In the drug volatilization device 1 configured as described above, in the non-volatilization state shown in Figures 2(a) and (b), for example, by holding the outer container 4 with the remaining four fingers excluding the index finger and applying pressure with the index finger to the first push button portion 31 protruding outside the outer container 4, the device can be switched from the non-volatilization state shown in Figures 2(a) and (b) to the maximum volatilization state as shown in Figures 1(a) and (b).

[0045] In the intermediate state (volatilization state) of switching from the non-volatilization state shown in Figure 4(b) to the maximum volatilization state shown in Figure 4(a), the inner opening 20 and the outer opening 50 partially overlap, connecting the inside of the inner container 3 with the outside of the outer container 4, and the volatilizable drug is volatilized according to the size of the overlapping area (ventilation area) of the inner opening 20 and the outer opening 50.

[0046] During the transition from the non-volatilization state shown in FIG. 4(b) to the maximum volatilization state shown in FIG. 4(a), the inner container 3 moves relative to the outer container 4 by applying a pressing force to the first push button 31. During this transition, the dynamic frictional force acting between the outward flange 65 and the locking protrusions 61, 62 on the inner container 3 and the inner surface of the outer container 4 provides an appropriate resistance. This allows for easy, continuous adjustment of the relative position of the inner container 3 with respect to the outer container 4. This allows for easy, continuous adjustment of the ventilation area. Thereafter, when the application of the pressing force to the first push button 31 is stopped, the static frictional force acting between the outward flange 65 and the locking protrusions 61, 62 on the inner container 3 and the inner surface of the outer container 4 maintains the ventilation area at the value it had when the application of the pressing force to the first push button 31 was stopped, thereby allowing for easy adjustment of the amount of volatilized drug.

[0047] 4(a), when the device is switched to the maximum volatilization state in which the overlapping area of ​​the inner opening 20 and the outer opening 50 is at its maximum, the pair of first locking protrusions 61 and the pair of first locking recesses 71 engage with each other at the relative positions of the inner container 3 and the outer container 4 where the drug volatilization device 1 is in the maximum volatilization state. As a result, the inner container 3 and the outer container 4 are locked by the pair of first locking protrusions 61 and the pair of first locking recesses 71, and the maximum volatilization state is stably maintained. In this maximum volatilization state, the volatilizable drug is volatilized to the maximum extent.

[0048] In the drug volatilization device 1, the volatile drug from the drug volatilizer 2 is volatilized from the inside of the inner container 3 to the outside of the outer container 4 through the inner opening 20, which includes the inner upper opening 23 (see Figure 3(a)) and the inner lower opening 24 (see Figure 3(b)), and the outer opening 50, which includes the outer upper opening 53 (see Figure 1(a)) and the outer lower opening 54 (see Figure 1(b)).This allows the amount of drug volatilization to be increased and the drug volatilization area to be expanded.

[0049] In the maximum volatilization state shown in FIG. 1(a), for example, by holding the outer container with the remaining four fingers (excluding the index finger) and applying pressure with the index finger to the second push button portion 32 protruding from the outer container 4, the maximum volatilization state shown in FIG. 1(a) can be switched to the non-volatilization state shown in FIG. 2(a). At this time, as shown in FIG. 4(b), at the relative positions of the inner container 3 and the outer container 4 where the drug volatilization device 1 is in the non-volatilization state, a pair of second locking protrusions 62 and a pair of second locking recesses 72 engage with each other. This locks the inner container 3 and the outer container 4 together with the pair of second locking protrusions 62 and the pair of second locking recesses 72, stably maintaining the non-volatilization state. In this non-volatilization state, the inner opening 20 and the outer opening 50 do not completely overlap, blocking the interior of the inner container 3 from the outside of the outer container 4.

[0050] In the non-volatilizing state shown in Figure 4(b), a labyrinth seal 80 formed by a pair of adjacent outward flange portions 65 and a pair of inward flange portions 75 can prevent volatile drug from leaking from between the inner container 3 and the outer container 4 (gap) when the drug volatilizing device 1 is in the non-volatilizing state.

[0051] In the drug volatilization device 1 of this embodiment, the operation of moving the inner container 3 relative to the outer container 4 can be performed with one hand. Therefore, the operability when moving the inner container 3 relative to the outer container 4 can be improved compared to the conventional drug volatilization device (Patent Document 1) in which the inner container 3 (inner box) could not be moved relative to the outer container 4 (outer box) without using both hands.

[0052] The chemical volatilization device 1 of 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 the configuration can be appropriately changed within the scope of the gist of the present invention. Specific other embodiments are as follows.

[0053] (Another embodiment 1) 5 is an external perspective view of a maximum volatilization state of a drug volatilization device 1A according to another embodiment 1 of the present invention. In the drug volatilization device 1A shown in FIG. 5, the outer container 4 is provided with a rectangular cylindrical container body 90 that is open in the left-right direction and has an outer front surface portion 41, an outer back surface portion 42, an outer upper surface portion 43, and an outer lower surface portion 44, a first lid member 91 that opens and closes one opening of the container body 90, and a second lid member 92 that opens and closes the other opening of the container body 90.

[0054] The first lid member 91 has a first insertion hole 91a through which the first push button 31 can be inserted, and is attached to the container body 90 via a hinge 95 so as to be able to open and close one opening of the outer container 4. When one opening of the container body 90 is closed, the first lid member 91 allows the first push button 31 to be inserted into the first insertion hole 91a. A sealing member 96 (corresponding to the "sealing means" of the present invention) made of, for example, a closed-cell sponge material is interposed between the periphery of the first insertion hole 91a and the outer circumferential surface of the first push button 31.

[0055] The second lid member 92 has a second insertion hole 92a through which the second push button 32 can be inserted, and is attached to the container body 90 via a hinge 97 so as to be able to open and close the other opening of the outer container 4. Similarly, with respect to the second lid member 92, when the other opening of the container body 90 is closed, the second push button 32 is inserted into the second insertion hole 92a. A seal member 98 (corresponding to the "sealing means" of the present invention) is interposed between the periphery of the second insertion hole 92a and the outer peripheral surface of the second push button 32.

[0056] According to another embodiment 1 of the drug volatilization device 1A, the outer container 4 comprises a container body 90 and lid members 91, 92 that open and close the opening of the container body 90, and has an opening and closing structure in which a portion (lid members 91, 92) opens and closes to allow the inner container 3 to be taken in and out.Therefore, by closing the lid members 91, 92, the airtightness between the inner container 3 and the outer container 4 can be increased, thereby making it possible to omit the labyrinth seal 80 in the above embodiment, and furthermore, by opening the lid members 91, 92, the inner container 3 can be easily taken in and out of the outer container 4.

[0057] (Alternative embodiment 2) Figure 6 is a front view of a drug volatilization device 1B according to another embodiment 2 of the present invention. Figure 6(a) is a diagram showing the maximum volatilization state, and Figure 6(b) is a diagram showing the non-volatilization state. In the drug volatilization device 1B shown in Figures 6(a) and (b), the outer container 4 comprises an outer container body 100 formed in the shape of a square tube that is rectangular when viewed from the front and has a hollow portion that is open in the vertical direction, and a pair of end structures 101 connected to one end side (upper end side) and the other end side (lower end side) of the outer container body 100, respectively.

[0058] As shown in Figures 6(a) and (b), the pair of end structures 101 respectively constitute the upper and lower parts of the outer container 4 in a mounted state in which the drug volatilization device 1B is placed on the mounting surface FL on which the drug volatilization device 1B is placed. In the pair of end structures 101, in the maximum volatilization state shown in Figure 6(a) and the non-volatilization state shown in Figure 6(b), the end structure 101 constituting the lower part of the outer container 4 functions as a base on which the drug volatilization device 1B is placed, thereby increasing the stability of the mounted state.

[0059] In the drug volatilization device 1B, the inner container 3 is inserted into the hollow portion of the outer container 4 so that the inner container 3 can move relative to the outer container 4 in the direction (up and down) in which the pressing force applied to the crescent-shaped first push button portion 31 and second push button portion 32 acts. The first push button portion 31 is hidden inside the outer container 4 in the maximum volatilization state shown in Figure 6(a), but protrudes (upward) from the outer container 4 in the non-volatilization state shown in Figure 6(b). The second push button portion 32 protrudes (upward) from the outer container 4 in the maximum volatilization state shown in Figure 6(a), but is hidden inside the outer container 4 in the non-volatilization state shown in Figure 6(b).

[0060] In the drug volatilization device 1B configured as described above, in the case of the non-volatilization state shown in Fig. 6(b), when the outer container 4 is turned upside down and the drug volatilization device 1B is placed on the placement surface FL, a pressing force is applied from the placement surface FL to the first push button portion 31 that protruded outward (upward) in the non-volatilization state shown in Fig. 6(b). This switches from the non-volatilization state shown in Fig. 6(b) to the maximum volatilization state shown in Fig. 6(a).

[0061] In the drug volatilization device 1B, in the case of the maximum volatilization state shown in Fig. 6(a), when the outer container 4 is turned upside down and the drug volatilization device 1B is placed on the placement surface FL, a pressing force is applied from the placement surface FL to the second push button portion 32 that protruded outward (upward) in the maximum volatilization state shown in Fig. 6(a). This switches from the maximum volatilization state shown in Fig. 6(a) to the non-volatilization state shown in Fig. 6(b).

[0062] In this way, by simply turning the outer container 4 upside down and placing the drug volatilization device 1B on the mounting surface FL, it is possible to easily switch between the maximum volatilization state shown in Figure 6(a) and the non-volatilization state shown in Figure 6(b).

[0063] (Alternative embodiment 3) In the above embodiment and alternative embodiments 1 and 2, examples have been shown in which the chemical volatilization devices 1, 1A, 1B are used in an upright position, but they can also be used in a lying position.

[0064] Figure 7 is an explanatory diagram of a medicine volatilization device 1 according to another embodiment 3 of the present invention. Figure 7(a) is an external perspective view of the medicine volatilization device 1 equipped with linear protrusions 110 in a maximum volatilization state. Figure 7(b) is a diagram showing a state in which the medicine volatilization device 1 equipped with linear protrusions 110 is used while lying down so that the outer front portion 41 faces the mounting surface FL.

[0065] As shown in FIG. 7(a), a pair of protrusions 110 are protruding from the outer front portion 41 of the outer container 4. The pair of protrusions 110 are disposed between the outer front openings 51 and the left and right side edges of the outer front portion 41, and have a trapezoidal cross section so as to extend linearly in the vertical direction when the medicine volatilization device 1 is in an upright position. The protrusions 110 can be formed integrally with the resin molding of the outer container 4 at the same time, or by attaching separately molded cushion rubber or the like to the outer container 4. As shown in FIG. 7(b), a pair of protrusions 110 are also protruding from the outer back portion 42 of the outer container 4.

[0066] In the drug volatilization device 1 of another embodiment 3 having the above-mentioned protrusions 110, as shown in Figure 7 (b), when the drug volatilization device 1 is used lying down so that the outer front surface 41 faces the mounting surface FL, a pair of protrusions 110 is interposed between the outer front surface 41 and the mounting surface FL. As a result, in the volatilization state (in this example, the maximum volatilization state), a bottom flow path Q is formed that leads from the inside of the inner container 3 to the outside of the outer container 4 through the inner front surface 21 (see Figure 7 (a)) and the outer front opening 51 (see Figure 7 (a)). Thus, as shown in Figure 7(b), even when the drug volatilization device 1 is used in a lying position, the inner opening 20 (inner front portion 21: see Figure 7(a)) and outer opening 50 (outer front opening 51: see Figure 7(a)) facing the mounting surface FL can be prevented from being blocked by the mounting surface FL, and the volatile drug from the drug volatilizer 2 can be volatilized to the outside of the outer container 4 by flowing through the bottom flow path Q that leads from the inside of the inner container 3 to the outside of the outer container 4. Although detailed explanation using illustrations is omitted, the usage form shown in Figure 7(b) is upside down, and even when the drug volatilization device 1 is used by laying it down so that the outer back portion 42 faces the mounting surface FL, a pair of protrusions 110 are interposed between the outer back portion 42 and the mounting surface FL, so a bottom flow path Q similar to the bottom flow path Q is formed, and the inner opening 20 (inner back opening 22: Figure 1(b)) and outer opening 50 (outer back opening 52: Figure 1(b)) facing the mounting surface FL can be prevented from being blocked by the mounting surface FL, and the volatile drug can be volatilized outside the outer container 4.

[0067] Fig. 7(c) is an external perspective view of the medicine volatilization device 1 equipped with the dot-like protrusions 120 in the maximum volatilization state. Fig. 7(d) is a state diagram showing the medicine volatilization device 1 equipped with the dot-like protrusions 120 when used while lying down so that the outer front surface 41 faces the mounting surface FL.

[0068] As shown in Figure 7(c), four truncated cone-shaped protrusions 120 are provided on the outer front surface 41 of the outer container 4 near the four corners of the outer front surface 41. Like the protrusions 110 described above, the protrusions 120 can be provided on the outer container 4 by molding them integrally with the resin molding of the outer container 4 at the same time, or by adhering separately molded cushion rubber or the like to the outer container 4. As shown in Figure 7(d), four protrusions 120 (only two visible to the reader's side are shown in Figure 7(d)) ​​are also provided on the outer back surface 42 of the outer container 4 in the same way.

[0069] In the drug volatilization device 1 of another embodiment 3 having the above-mentioned protrusions 120, as shown in Figure 7 (d), when the drug volatilization device 1 is used lying down so that the outer front surface 41 faces the mounting surface FL, four protrusions 120 are interposed between the outer front surface 41 and the mounting surface FL. As a result, in the volatilization state (in this example, the maximum volatilization state), a bottom flow path Q is formed that leads from the inside of the inner container 3 to the outside of the outer container 4 via the inner front surface 21 (see Figure 7 (c)) and the outer front opening 51 (see Figure 7 (c)). Thus, as shown in Figure 7(d), even when the drug volatilization device 1 is used in a lying position, the inner opening 20 (inner front portion 21: see Figure 7(c)) and outer opening 50 (outer front opening 51: see Figure 7(c)) facing the mounting surface FL can be prevented from being blocked by the mounting surface FL, and the volatile drug from the drug volatilizer 2 can be volatilized to the outside of the outer container 4 by flowing through the bottom flow path Q that leads from the inside of the inner container 3 to the outside of the outer container 4. Although detailed explanation using illustrations is omitted, the usage form shown in Figure 7(d) is upside down, and even when the drug volatilization device 1 is used by laying it down so that the outer back portion 42 faces the mounting surface FL, four protrusions 120 are interposed between the outer back portion 42 and the mounting surface FL, so a bottom flow path Q similar to the bottom flow path Q is formed, and the inner opening 20 (inner back opening 22: see Figure 1(b)) and outer opening 50 (outer back opening 52: see Figure 1(b)) facing the mounting surface FL can be prevented from being blocked by the mounting surface FL, and the volatile drug can be volatilized outside the outer container 4.

[0070] (Alternative embodiment 4) In the above embodiment and other embodiments 1 to 3, examples have been shown in which the drug volatilization devices 1, 1A, and 1B are used while placed on a mounting surface, but the drug volatilization devices can also be used while attached to an attachment target. For example, the drug volatilization device can be attached to a wall of a room or hung from the ceiling. In this case, the wall or ceiling of the room is the attachment target for the drug volatilization device. With such an attachment-type drug volatilization device, it is possible to use the drug volatilization device in the treatment space even in situations where there is not enough space on the floor or stand, making it difficult to mount the drug volatilization device.

[0071] The attachment-type chemical volatilization device is particularly useful when attached to the sun visor installed in an automobile. Since the sun visor is located directly under the roof behind the windshield of the automobile when not in use, for example, a clip (which may be hook-shaped) can be attached to the outer container of the chemical volatilization device, and the clip can be clipped to the sun visor to attach the chemical volatilization device. In this case, the chemical volatilization device can be used as a car air freshener or insect repellent.

[0072] In this way, when the pesticide volatilization device is attached to the sun visor, it is not directly exposed to sunlight, so the effects of ultraviolet rays and high temperatures are reduced compared to when it is installed on a dashboard, etc. As a result, deterioration of the materials that make up the pesticide volatilization device and the pesticide contained in the pesticide volatilization device are suppressed, and excessive volatilization of the pesticide can also be suppressed. Moreover, compared to when it is installed on a dashboard, it does not obstruct the driver's view as much, so it has great benefits in terms of safety. [Industrial Applicability]

[0073] The chemical volatilization device of the present invention can be used not only as a device for volatilizing air fresheners and deodorants, but also particularly effectively for exterminating or repelling flying pests such as mosquitoes, midges, and moth flies, as well as mites and crawling pests.
