Description

[Technical field]

[0001] The present invention relates to a drug volatilization device comprising a drug volatilization body that holds a volatile drug in a volatilizable manner, an inner container that houses the drug volatilization body, 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 insecticides (see, for example, Patent Document 1).

[0003] Patent Document 1 discloses a chemical volatilization device which comprises an inner box with an air vent, an outer box with air vent adjustment holes, and a volatile chemical (a fragrance deodorant) stored in the inner box, the outer box being slidably attached to the inner box, and the outer box being slid relative to the inner box to bring the air vent and the air vent adjustment holes into communication, thereby volatilizing the fragrance deodorant into the outside air through the air vent and the air vent adjustment holes.

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 55-131748 Summary of the Invention [Problem to be solved by the invention]

[0005] In the drug volatilization device of Patent Document 1, when sliding the outer box relative to the inner box, for example, the inner box is held with the left hand and the outer box is held with the right hand, and the outer box is moved relative to the inner box. In this way, in the drug volatilization device of Patent Document 1, the outer box cannot be moved relative to the inner box unless both hands are used, and it can be said that there is room for improvement in the operability when moving the outer box relative to the inner 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 outer container relative to the inner container, and that has improved operability when moving the outer container relative to the inner container. [Means for solving the problem]

[0007] The characteristic configuration of the drug volatilization device according to the present invention for solving the above problems is as follows: A drug volatilization device comprising a drug volatilization body that holds a volatile drug in a volatilizable manner, an inner container that contains the drug volatilization body, and an outer container that is disposed outside the inner container, The inner container has a pressing portion to which a pressing force is applied and an inner opening, the outer container has an outer opening corresponding to the inner opening; The outer container is configured to be movable relative to the inner container along a direction in which the pressing force applied to the pressing portion acts, When the outer container is moved relative to the inner container, the inner opening and the outer opening are at least partially overlapping, thereby enabling switching between a volatilization state in which the inside of the inner container is connected to 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 off the inside of the inner container from the outside of the outer container.

[0008] According to the drug volatilization device of this configuration, the inner container has a pressing part to which a pressing force is applied, and the outer container is configured to be movable relative to the inner container along the direction in which the pressing force applied to the pressing part acts. Then, by moving the outer container relative to the inner container, the inner opening and the outer opening are at least partially overlapped, so that the inside of the inner container communicates with the outside of the outer container, and the inner opening and the outer opening are not completely overlapped, so that the inside of the inner container and the outside of the outer container are switched to a non-volatilization state in which the inside of the inner container and the outside of the outer container are blocked. In this way, in the drug volatilization device configured to be able to switch between a volatilization state and a non-volatilization state by moving the outer container relative to the inner container, for example, while holding the pressing part with the index finger, the outer container is grasped with the thumb and middle finger, and while applying a pressing force to the pressing part with the index finger to obtain a reaction force, the force from the thumb and middle finger is applied to the outer container in the opposite direction to the direction in which the pressing force applied to the pressing part acts, so that the operation of moving the outer container relative to the inner container can be performed with one hand. Therefore, the operability of moving the outer container relative to the inner container can be improved compared to conventional drug volatilization devices (Patent Document 1), in which the outer container (outer box) could not be moved relative to the inner container (inner box) without using both hands.

[0009] In the drug volatilization device according to the present invention, A push button forming the push portion; a lever member that converts the pressing force applied to the push button into a driving force that moves the outer container relative to the inner container; It is preferable to have

[0010] According to the medicine volatilization device of this configuration, the pressing force applied to the push button forming the pressing part is converted by the lever member into a driving force that moves the outer container relative to the inner container. This allows the outer container to be moved relative to the inner container with a single touch of the push button, thereby further improving operability.

[0011] In the drug volatilization device according to the present invention, the inner opening includes an inner bottom opening formed in a bottom of the inner container; In the volatilization state, a bottom flow path is formed that leads from the inside of the inner container to the outside of the outer container via the inner bottom opening, It is preferable that, in the non-volatilized state, the bottom flow path is blocked by the outer container.

[0012] According to the drug volatilization device of this configuration, in the volatilization state, 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 part where the inner opening and the outer opening are at least partially overlapped, and the volatile drug from the drug volatilizer is volatilized to the outside of the outer container by flowing through the bottom flow path that leads from the inside of the inner container to the outside of the outer container through the inner bottom opening. Therefore, the amount of drug volatilization can be further increased. On the other hand, in the non-volatilization state, the inside of the inner container and the outside of the outer container are blocked by the inner opening and the outer opening not being completely overlapped, and the bottom flow path is blocked by the outer container, so that the volatilization of the volatile drug can be stopped when it is not necessary to volatilize the volatile drug to the outside of the outer container.

[0013] In the drug volatilization device according to the present invention, It is preferable that the container further comprises a holding means for holding the outer container while continuously adjusting the relative position of the outer container with respect to the inner container.

[0014] In the volatilization state, the inner opening and the outer opening are at least partially overlapped to form an air vent that connects the inside of the inner container to the outside of the outer container. This air vent expands or contracts according to the change in the relative position of the outer container to the inner container. Therefore, the size of the air vent (air vent area) changes according to the change in the relative position of the outer container to the inner container. According to the drug volatilization device of this configuration, the size of the air vent (air vent area) is adjusted steplessly by the holding means that holds the outer container while adjusting the relative position of the outer container to the inner container steplessly, so that the amount of volatilization of the volatile drug can be adjusted steplessly.

[0015] In the drug volatilization device according to the present invention, The inner container and the outer container are preferably colored so that their exterior colors are different from each other.

[0016] According to the drug volatilization device of this configuration, the inner container and the outer container are colored so that the exterior colors are different from each other, so that the change in state between the volatilization state and the non-volatilization state due to the relative movement of the outer container with respect to the inner container is more easily visually recognized, and it is possible to accurately determine whether the state is in the volatilization state or the non-volatilization state by visual inspection. In addition, it is also easier to visually recognize how the size of the part where the inner opening and the outer opening are at least partially overlapped changes with the relative movement of the outer container with respect to the inner container, so that it is easier to adjust the ventilation area and the amount of volatilization of the volatile drug can be more easily adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Hereinafter, the present invention will be described 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.

[0019] First Embodiment <Overall composition> Fig. 1 is an external perspective view of the drug volatilization device 1A of the first embodiment. Fig. 1(a) shows a non-volatilization state, and Fig. 1(b) shows a maximum volatilization state in which the amount of volatilization of the drug volatilization device 1A is maximum. As shown in Figs. 1(a) and (b), the drug volatilization device 1A is a free-standing type suitable for use in a room, entrance, etc., and is formed in a square prism shape from the outside.

[0020] FIG. 2 is a vertical cross-sectional view showing a non-volatilized state of the drug volatilization device 1A of the first embodiment. In FIG. 2, the size and positional relationship of each member and each opening 21, 37, 38, 51, etc. constituting the drug volatilization device 1A are shown exaggerated or simplified for ease of understanding, and do not strictly reflect the actual size (similar to FIGS. 3, 4, 6 to 9). As shown in FIG. 2, the drug volatilization device 1A includes a drug volatilization body 2 that holds a volatile drug in a volatilizable manner, an inner container 3 that contains the drug volatilization body 2, and an outer container 4 that is disposed outside the inner container 3 and contains the inner container 3. In the drug volatilization device 1A, the inner container 3 and the outer container 4 form a storage container 5 having a nested structure (double structure). The inner container 3 and the outer container 4 constituting the storage container 5 can be produced by a known resin molding method such as injection molding using resin as a material, but are not limited thereto.

[0021] <Volatile drugs> The volatile agent may be an insecticide, a repellent, a fungicide, an antibacterial agent, an aromatic agent, a deodorant, a synergist, etc., used alone or in combination, but is not particularly limited. 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, and in particular, pyrethroid compounds that are volatile at room temperature, such as metofluthrin, profluthrin, empenthrin, and transfluthrin, which have high volatilization performance and control effect against flying pests, are suitable. In addition, the volatile agent may be used in combination with a known hardly volatile agent, etc.

[0022] <Drug volatilization body> As the drug volatilizer 2, for example, a structure that holds a volatile drug in a volatile manner by impregnation or kneading can be used. Examples of the material of the drug volatilizer 2 include paper, pulp, natural fibers, synthetic fibers, resin bodies, resin sheets, inorganic or organic porous bodies, gel bodies, etc. Although the method of impregnating a resin sheet with a drug is simple, it is preferable to adopt a resin body kneaded with a volatile drug because it is easy to control the sustained release of the volatile drug during the use period, the amount of drug volatilization is stable, and the drug is prevented from running off due to moisture such as rain, but it is not particularly limited. Examples of the resin of the resin body and the resin sheet include polyethylene, polypropylene, polyvinyl alcohol, polyvinyl acetate, polybutadiene, polyisoprene, ethylene-vinyl acetate copolymer, ethylene-methyl methacrylate copolymer, styrene-butadiene copolymer, etc. The shape 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 planar or three-dimensional mesh structure, etc. can be adopted.

[0023] <Inner container> Fig. 4(a) is a vertical cross-sectional view showing the structure of the inner container 3. As shown in Fig. 4(a), the inner container 3 has an inner peripheral wall portion 11 in the shape of a rounded square cylinder extending in the vertical direction (up-down direction), a lid portion 12 closing the upper end side of the inner peripheral wall portion 11, and a bottom portion 13 closing the lower end side of the inner peripheral wall portion 11. Although detailed explanation using illustrations is omitted for the inner container 3, the inner peripheral wall portion 11, the lid portion 12, and the bottom portion 13 are assembled so that they can be disassembled into their respective parts, for example, by a known fitting structure with a tightening margin, a known locking structure by engagement between a recess and a protrusion, or a fastening structure by screwing a male screw and a female screw.

[0024] <Inner opening> The inner peripheral wall portion 11 has inner peripheral surface openings 21 (corresponding to the "inner openings" of the present invention). The inner peripheral surface openings 21 penetrate the inner peripheral wall portion 11 so as to penetrate between the inside and outside of the inner container 3, and are formed in the shape of horizontally long slits along the wall surface of the inner peripheral wall portion 11. The inner peripheral surface openings 21 are disposed at a predetermined pitch in the vertical direction in the region between the upper region and the lower region of the inner peripheral wall portion 11.

[0025] The outer peripheral surface of the inner peripheral wall portion 11 is provided with a protrusion 22 capable of coming into contact with the inner peripheral surface of the outer container 4 (the outer peripheral wall portion 41 described below). The protrusion 22 is disposed at the upper end portion of the inner peripheral wall portion 11. The protrusion 22 may be provided in any form so long as it can come into uniform contact with the inner peripheral surface of the outer peripheral wall portion 41 without being biased in the circumferential direction, and is not particularly limited. For example, the protrusion 22 may be provided in a form protruding continuously in a ring shape (rounded square ring) in the circumferential direction of the inner peripheral wall portion 11, or a form in which a plurality of protrusions are provided at a predetermined pitch at key points in the circumferential direction of the inner peripheral wall portion 11.

[0026] <Holding means> The protrusion 22 functions as a holding means for holding the relative position of the outer container 4 with respect to the inner container 3 while continuously adjusting the position. That is, when a predetermined or greater operating force is applied to the outer container 4 so as to move the outer container 4 vertically relative to the inner container 3, the protrusion 22 frictionally engages with the inner circumferential surface of an outer peripheral wall portion 41 described later so as to allow the outer container 4 to move vertically relative to the inner container 3. In addition, when the operating force is not applied to the outer container 4 and only gravity is acting, the protrusion 22 frictionally engages with the inner circumferential surface of the outer peripheral wall portion 41 so as to generate a frictional force against gravity acting on the outer container 4 (the weight of the outer container 4) between the outer container 4 and the inner circumferential surface of the outer peripheral wall portion 41 in order to maintain the current relative position of the outer container 4 with respect to the inner container 3.

[0027] The lid portion 12 has a lid body 31 in the shape of a flat plate with rounded corners, a push portion 32 in the shape of a rounded rectangular prism that protrudes integrally from the lid body 31 at the center of the upper surface side of the lid body 31, and a frame portion 33 that is vertically attached to the underside of the lid body 31.

[0028] The lid body 31 is fitted into the inner peripheral side of the inner peripheral wall portion 11 and disposed at a height position of the upper end of the inner peripheral wall portion 11. A step portion 34 that abuts against the lid body 31 disposed at this height position is provided on the inner peripheral wall portion 11, and the lid body 31 cannot move below this height position by abutting against the step portion 34. The lid body 31 is fitted into the inner peripheral wall portion 11 with a predetermined tightening margin so that the lid body 31 can be pulled upward from the inner peripheral wall portion 11 when a pulling force of a predetermined or greater is applied in the pulling direction.

[0029] <Pressing part> The pressing portion 32 is adapted to receive pressure, for example, from the index finger, when switching from the non-volatile state to the volatile state, as described below, and the area of ​​the upper surface, which is the pressing surface, is set so as to be large enough to be pressed with the pad of the index finger.

[0030] The frame portion 33 has a retaining piece (not shown) that holds required portions of the periphery of the drug volatilizer 2, and is configured to support the drug volatilizer 2 in a predetermined position inside the inner peripheral wall portion 11, for example, an upright position with the longitudinal direction facing up and down.

[0031] <Bottom> The bottom portion 13 has a bottom surface portion 35 shaped like an inverted quadrangular pyramid, and legs 36 disposed at the four corners of the bottom surface portion 35 .

[0032] <Inner bottom opening> 5 is a perspective view of the bottom 13 of the inner container 3 from below. As shown in FIG. 5, a plurality of triangular inner bottom openings 37 (corresponding to the "inner opening" of the present invention) are formed in the bottom surface portion 35 so as to be positioned around the center of the bottom surface portion 35 with their apex angles pointing toward the center of the bottom surface portion 35 at the center when viewed from the bottom, and a plurality of slit-shaped inner bottom openings 38 (corresponding to the "inner opening" of the present invention) are formed at a predetermined pitch in a direction proceeding obliquely upward along the side surface of the bottom surface portion 35 shaped like an inverted pyramid so as to surround the inner bottom openings 37. Note that in the inner container 3, the inner bottom openings 37, 38 are optional components rather than essential components, and there is also an embodiment in which the inner container 3 is constituted only by the inner peripheral opening 21.

[0033] <Bottom channel> Fig. 3 is a vertical cross-sectional view showing a maximum volatilization state in which the amount of volatilization of the drug volatilization device 1A of the first embodiment is maximized. As shown in Fig. 3, the leg length of the leg portion 36 is set so that the bottom portion 35 is located above the mounting surface (FL) on which the drug volatilization body 1A is placed without contacting the bottom portion 35. Since the bottom portion 35 is located above the mounting surface (FL) in this way, 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 bottom openings 37 and 38.

[0034] <Outer container> Fig. 4(b) is a vertical cross-sectional view showing the structure of the outer container 4. As shown in Fig. 4(b), the outer container 4 has an outer peripheral wall portion 41 in the shape of a rounded rectangular cylinder extending in the vertical direction, and a top plate portion 42 that is integrally provided with the outer peripheral wall portion 41 so as to close the upper end side of the outer peripheral wall portion 41, and the lower end side is open so that the inner container 3 can be inserted from the lower end side.

[0035] The outer peripheral wall portion 41 has an inner peripheral surface that faces the outer peripheral surface of the inner peripheral wall portion 11 when the outer container 4 is fitted onto the inner container 3 (see FIGS. 2 and 3). The outer peripheral wall portion 41 is movable up and down relative to the inner peripheral wall portion 11 with the inner peripheral surface of the outer peripheral wall portion 41 in sliding contact with the outer peripheral surface of the inner peripheral wall portion 11 or in close proximity with a small gap therebetween.

[0036] The outer peripheral wall 41 is provided with a step 43 that comes into contact with the protrusion 22 provided on the inner peripheral wall 11 in the maximum volatilization state (see FIG. 3). Thus, the outer container 4 cannot move above the height position where the protrusion 22 and the step 43 come into contact, and is fitted onto the inner container 3 in a state in which it will not come off unexpectedly. In this way, the protrusion 22 functions alone as a holding means for holding the outer container 4 while continuously adjusting the relative position of the outer container 4 with respect to the inner container 3, and cooperates with the step 43 to form a separation prevention means for preventing the outer container 4 from coming off unexpectedly from the inner container 3. In addition, the protrusion 22 cooperates with the step portion 43 to form a positioning means for accurately positioning the outer container 4 relative to the inner container 3 so that the outer peripheral opening 51 moves upward by one arrangement pitch of the inner peripheral opening 21 and the outer peripheral opening 51 from the relative position of the outer peripheral opening 51 to the inner peripheral opening 21 in the non-volatilization state shown in Fig. 2 to reach the maximum volatilization state shown in Fig. 3, i.e., the state in which the inner peripheral opening 21 and the outer peripheral opening 51 completely overlap. When an operating force of a certain level or more is intentionally applied to the outer container 4 in a direction to pull it away from the inner container 3, the state in which the protrusion 22 and the step portion 43 are in contact and engaged is released due to elastic deformation of the protrusion 22 and / or the step portion 43, and the outer container 4 can be pulled away and separated from the inner container 3.

[0037] <Outside opening> The outer peripheral wall portion 41 has an outer peripheral opening portion 51 (corresponding to the "outer opening portion" of the present invention) that is set to have the same opening shape and the same opening area as the inner peripheral opening portion 21 so as to correspond to the inner peripheral opening portion 21. The outer peripheral opening portion 51 is formed in a horizontally long slit shape that penetrates the outer peripheral wall portion 41 so as to penetrate the inside and outside of the outer container 4 and runs along the wall surface of the outer peripheral wall portion 41. The outer peripheral opening portion 51 is arranged in the vertical direction at the same pitch as the inner peripheral opening portion 21 is arranged in the region between the upper region and the lower region of the outer peripheral wall portion 41. In this embodiment, an example is shown in which the inner peripheral opening portion 21 and the outer peripheral opening portion 51 are set to have the same opening shape and the same opening area, but the present invention is not limited to this. For example, if it is possible to switch between a volatilization state in which the inside of the inner container 3 is connected to the outside of the outer container 4 by at least partially overlapping the inner circumferential opening 21 and the outer circumferential opening 51, and a non-volatilization state in which the inside of the inner container 3 is blocked from the outside of the outer container 4 by completely not overlapping the inner circumferential opening 21 and the outer circumferential opening 51, it is also possible to set the inner circumferential opening 21 and the outer circumferential opening 51 to different opening shapes and / or different opening areas.

[0038] The top plate portion 42 has a lower surface that faces the upper surface of the lid body 31 of the lid portion 12 when the outer container 4 is fitted onto the inner container 3 (see Figs. 2 and 3). On the upper surface side of the top plate portion 42, an annular flat surface 42a is formed in a rounded rectangular annular region near the outer periphery, and a central flat surface 42b is formed that is recessed with a step from the annular flat surface 42a in the region surrounded by the annular flat surface 42a. A rounded rectangular insertion hole 42c is drilled in the center of the top plate portion 42, penetrating between the lower surface of the top plate portion 42 and the central flat surface 42b, and through which the pressing portion 32 can be inserted.

[0039] <How to use> A method of using the chemical volatilization device 1A configured as described above will be described mainly with reference to Figs. 2 and 3, and Fig. 1 as necessary.

[0040] In the drug volatilization device 1A shown in FIG. 2, the drug volatilizer 2 is set inside the frame 33, and the inner container 3, which is constructed by assembling the inner peripheral wall 11, the lid 12, and the bottom 13, is placed on the placement surface (FL) so that the legs 36 abut against the placement surface (FL) in a vertical orientation so that the pressing portion 32 faces upward. In the drug volatilization device 1A, the outer container 4 is fitted onto the inner container 3 so that the outer peripheral surface of the inner peripheral wall 11 faces the inner peripheral surface of the outer peripheral wall 41, and the upper surface of the lid main body 31 faces the lower surface of the top plate 42, and the protrusion 22 is frictionally engaged with the inner peripheral surface of the outer peripheral wall 41 so as to function as the above-mentioned holding means, etc. In the drug volatilization device 1A, the outer container 4 is movable (reciprocating) relative to the inner container 3 in the vertical direction along the direction in which the pressing force applied to the pressing portion 32 acts (vertical direction).

[0041] 2, when the upper surface of the lid body 31 and the lower surface of the top plate portion 42 are in contact with each other, the projection 22 is located above the step portion 43 and spaced apart by a distance corresponding to one arrangement pitch of the inner peripheral opening 21 and the outer peripheral opening 51. When viewed in a direction in which the outer peripheral surface of the inner peripheral wall portion 11 and the inner peripheral surface of the outer peripheral wall portion 41, which are arranged opposite to each other, overlap, the inner peripheral opening 21 and the outer peripheral opening 51 are vertically shifted by one arrangement pitch of the openings 21, 51, and the inner peripheral opening 21 is completely blocked by the wall portion between the outer peripheral openings 51 adjacent in the vertical direction in the outer peripheral wall portion 41 (a state in which the inner peripheral opening 21 and the outer peripheral opening 51 do not completely overlap), thereby isolating the inside of the inner container 3 from the outside of the outer container 4. Furthermore, the lower end of the outer peripheral wall portion 41 abuts against the placement surface (FL), and the bottom flow path Q (see FIG. 3) that leads from the inside of the inner container 3 to the outside of the outer container 4 through the inner bottom openings 37, 38 is blocked by the lower part of the outer peripheral wall portion 41. The state shown in FIG. 2 is a non-volatilization state in which even if the volatile drug is volatilized from the drug volatilizer 2 inside the inner container 3, the inside of the inner container 3 and the outside of the outer container 4 are blocked, so that the volatile drug cannot spread outside the outer container 4.

[0042] The drug volatilization device 1A in the non-volatilization state shown in FIG. 2 can be put into the maximum volatilization state shown in FIG. 3 by, for example, performing the following operation. First, as shown in FIG. 1(a), while holding the pressing part 32 with the index finger, the outer container 4 is grasped with the thumb and middle finger, and while applying a pressing force to the pressing part 32 with the index finger to obtain a reaction force, the force from the thumb and middle finger is applied to the outer container 4 in the opposite direction (upward) to the direction in which the pressing force applied to the pressing part 32 acts (downward). At this time, when the force from the thumb and middle finger exceeds the resultant force of the gravity acting on the outer container 4 and the static friction force generated between the protrusion 22 and the inner peripheral surface of the outer peripheral wall part 41, the outer container 4 starts to move relative to the inner container 3. Thereafter, by continuing to apply to the outer container 4 a force exceeding the resultant force of the gravity acting on the outer container 4 and the kinetic friction force generated between the protrusion 22 and the inner peripheral surface of the outer peripheral wall part 41, the outer container 4 can be moved upward relative to the inner container 3 until the step part 43 abuts against the protrusion 22. Even if the hand is released from the outer container 4 after the step portion 43 abuts against the projection 22, the projection 22 is frictionally engaged with the inner peripheral surface of the outer peripheral wall portion 41, so that the relative position of the outer container 4 with respect to the inner container 3 when the projection 22 and the step portion 43 abut against each other is maintained. In this way, the maximum volatilization state shown in FIG. 3 can be maintained. In addition, in the maximum volatilization state shown in FIG. 3, one hand is placed on the upper surface of the outer container 4, a pressing force exceeding the frictional force (static friction force, kinetic friction force) generated between the projection 22 and the inner peripheral surface of the outer peripheral wall portion 41 is applied to the outer container 4, and the outer container 4 is pushed downward relative to the inner container 3 until the lower surface of the top plate portion 42 contacts the upper surface of the lid main body 31 (until the lower end of the outer peripheral wall portion 41 abuts against the placement surface (FL)), thereby making it possible to bring the outer container 4 into the non-volatilization state shown in FIG. 2.

[0043] In this way, the operation of moving the outer container 4 upward and downward relative to the inner container 3 can be performed with one hand, thereby improving operability when moving the outer container 4 relative to the inner container 3 compared to conventional drug volatilization devices (Patent Document 1), which required the use of both hands to move the outer container 4 (outer box) relative to the inner container 3 (inner box).

[0044] In the drug volatilization device 1A shown in FIG. 3, when viewed in a direction in which the outer peripheral surface of the inner peripheral wall portion 11 and the inner peripheral surface of the outer peripheral wall portion 41, which are arranged opposite to each other, are overlapped, the inner peripheral surface opening 21 and the outer peripheral surface opening 51 are completely overlapped, and the inner peripheral surface opening 21 and the outer peripheral surface opening 51 are overlapped, so that the ventilation area of ​​the vent hole portion 60 formed to communicate the inside of the inner container 3 with the outside of the outer container 4 is maximized. Similarly, the flow path cross-sectional area between the lower end of the outer peripheral wall portion 41 and the mounting surface (FL) in the bottom flow path Q formed to communicate from the inside of the inner container 3 to the outside of the outer container 4 through the inner bottom surface openings 37 and 38 is also maximized. The state shown in FIG. 3 is a maximum volatilization state in which the ventilation area of ​​the vent hole portion 60 is maximum and the flow path cross-sectional area of ​​the bottom flow path Q is maximum, so that the amount of volatilizable drug volatilized from the inside of the inner container 3 to the outside of the outer container 4 is maximum. In the following description, unless otherwise specified, the flow path cross-sectional area of ​​the bottom flow path Q refers to the flow path cross-sectional area in the bottom flow path Q between the lower end of the outer peripheral wall portion 41 and the mounting surface (FL).

[0045] Fig. 6 is a vertical cross-sectional view showing the volatilization amount adjustment state of the medicine volatilization device 1A of the first embodiment. As shown in Fig. 6, even if the hand is released from the outer container 4 before the step portion 43 abuts against the protrusion 22, the protrusion 22 is frictionally engaged with the inner peripheral surface of the outer peripheral wall portion 41, so that the relative position of the outer container 4 with respect to the inner container 3 at the time when the hand is released from the outer container 4 is maintained. In the volatilization amount adjustment state shown in Figure 6, when viewed in the direction in which the outer peripheral surface of the opposing inner peripheral wall portion 11 and the inner peripheral surface of the outer peripheral wall portion 41 overlap, there are areas where the inner peripheral opening 21 and the outer peripheral opening 51 partially overlap, and areas where the inner peripheral opening 21 and the outer peripheral opening 51 do not overlap. The inner peripheral opening 21 and the outer peripheral opening 51 overlap at least partially, and the air vent portion 60 formed to communicate between the inside of the inner container 3 and the outside of the outer container 4 expands or contracts depending on the direction and amount of relative movement of the outer container 4 with respect to the inner container 3, in other words, depending on the change in the relative position of the outer container 4 with respect to the inner container 3. The bottom flow path Q formed so as to communicate from the inside of the inner container 3 to the outside of the outer container 4 through the inner bottom openings 37 and 38 has an area that is not blocked by the lower part of the outer peripheral wall 41 and an area that is partially blocked by the outer peripheral wall 41, and expands or contracts according to the change in the relative position of the outer container 4 to the inner container 3. For example, the size (ventilation area) of the vent hole 60 and the size (flow path cross-sectional area) of the bottom flow path Q can be changed by adjusting the timing of releasing the outer container 4 or by appropriately pushing the outer container 4 relative to the inner container 3 to move it downward relative to the inner container 3. The relative position of the outer container 4 to the inner container 3 is maintained while being adjusted in a stepless manner by the protrusion 22 frictionally engaging with the inner peripheral surface of the outer peripheral wall 41, so that the size (ventilation area) of the vent hole 60 and the size (flow path cross-sectional area) of the bottom flow path Q are adjusted in a stepless manner, and the amount of volatilization of the volatile drug can be adjusted in a stepless manner.

[0046] According to the first embodiment of the drug volatilization device 1A, by a simple operation of moving the outer container 4 upward and downward relative to the inner container 3 with one hand, the volatile drug can be volatilized outside the outer container 4 in an adjustable amount when needed, and the volatilization of the volatile drug can be stopped when there is no need to volatilize the volatile drug outside the outer container 4.

[0047] In Fig. 1, the inner container 3 (inner peripheral wall 11) is shown filled in black so that it is easy to visually understand that the exterior color of the inner container 3 (inner peripheral wall 11) is different from the exterior color of the outer container 4 (similarly in Fig. 10). As shown in Fig. 1, the inner container 3 and the outer container 4 are preferably colored so that their exterior colors are different from each other, for example, by combining brown and white, white and green, etc. In this way, by making the exterior colors of the inner container 3 and the outer container 4 different from each other, it becomes easier to visually recognize the state change between the non-volatilization state (see Fig. 2) and the volatilization state (see Fig. 3) due to the relative movement of the outer container 4 with respect to the inner container 3, and it is possible to visually accurately determine whether the outer container 4 is in the volatilization state or the non-volatilization state. In addition, it is easier to visually recognize how the size of the overlapping portion (air vent portion 60) of the inner peripheral opening 21 and the outer peripheral opening 51 changes with the relative movement of the outer container 4 with respect to the inner container 3, making it easier to adjust the air vent area and more easily adjust the amount of volatilized drug that evaporates.

[0048] Second Embodiment Fig. 7 is an external perspective view of the drug volatilization device of the second embodiment. Fig. 8 is a longitudinal sectional view showing the non-volatilization state of the drug volatilization device 1B of the second embodiment. In the second embodiment, the same or similar parts as those of the first embodiment are given the same reference numerals in the drawings, and detailed descriptions thereof are omitted. In the following, the description will be focused on the parts unique to the second embodiment.

[0049] As shown in Fig. 8, in the second embodiment of the drug volatilization device 1B, the inner peripheral wall portion 11 has an extension portion 11a that extends upward and protrudes. Since the inner peripheral wall portion 11 has the extension portion 11a, the top plate portion 42 is raised with respect to the lid main body 31, and a space capable of accommodating a flange portion 72b and a lever member 75 described later is formed between the lid main body 31 and the top plate portion 42.

[0050] <Push button> In the drug volatilization device 1B, the lid portion 12 has a support post 71 protruding from the center of the upper surface side of the lid body 31, and a push button 72 supported by the support post 71 so as to be movable in the vertical direction. In the drug volatilization device 1B, the push button 72 corresponds to the above-mentioned push portion 32 to which a pushing force is applied by the index finger when switching from the non-volatilization state to the volatilization state. The push button 72 has a button body 72a having a pushing surface set to an area sufficient to be pressed by the pad of the index finger, and a flange portion 72b formed to protrude outward from the lower portion of the button body 72a and disposed between the lid body 31 and the top plate portion 42.

[0051] <Lever component> A lever member 75 is disposed between the lid body 31 and the top plate 42. The lever member 75 has a fulcrum portion 75a, an input arm portion 75b, and an output arm portion 75c. The fulcrum portion 75a is rotatably supported by a pivot shaft 77 attached via a bracket 76 to the upper surface side of the lid body 31. The input arm portion 75b extends from the fulcrum portion 75a toward the flange portion 72b of the push button 72, and its tip portion is in sliding contact with the flange portion 72b. The output arm portion 75c extends from the fulcrum portion 75a toward the top plate 42 so as to be substantially perpendicular to the input arm portion 75b, and its tip portion is in sliding contact with the top plate 42.

[0052] 9 is a vertical cross-sectional view showing a maximum volatilization state in which the amount of volatilization of the medicine volatilization device 1B of the second embodiment is maximized. As shown in FIG. 9, in the medicine volatilization device 1B, for example, when the pressing surface (upper surface) of the button body 72a is pressed with the index finger, the pressing force applied to the button body 72a is transmitted to the input arm portion 75b via the flange portion 72b, and the input arm portion 75b is pressed down, and the output arm portion 75c is rotated upward around the pivot shaft 77. As a result, the top plate portion 42 that is in sliding contact with the output arm portion 75c is pushed up, and the outer container 4 is moved upward relative to the inner container 3.

[0053] According to the second embodiment of the drug volatilization device 1B, the pressing force applied to the push button 72 is converted by the lever member 75 into a driving force that moves the outer container 4 upward relative to the inner container 3, so that the non-volatilization state shown in FIG. 8 to the maximum volatilization state shown in FIG. 9 can be switched by a one-touch operation of simply pressing the push button 72 with the index finger as shown in FIG. 7(a), thereby improving operability. In addition, in the maximum volatilization state shown in FIG. 9, one hand is placed on the upper surface of the outer container 4, and a pressing force exceeding the resultant force of the friction force (static friction force, kinetic friction force) generated between the protrusion 22 and the inner surface of the outer peripheral wall portion 41 and the mechanical friction force generated between the flange portion 72b, the top plate portion 42, and the lever member 75 is applied to the outer container 4, and the outer container 4 is pushed downward relative to the inner container 3 until the lower end of the outer peripheral wall portion 41 abuts against the placement surface (FL), thereby making it possible to put the outer container 4 into the non-volatilization state shown in FIG. 8.

[0054] The above describes the drug volatilization device of the present invention based on several embodiments, but the present invention is not limited to the configurations described in the above embodiments, and the configuration can be changed as appropriate within the scope of the invention.

[0055] (Another embodiment 1) FIG. 10 is an explanatory diagram of another embodiment 1. FIG. 10(a) shows a non-volatilization state, and FIG. 10(b) shows a maximum volatilization state. In the above embodiment, an example was shown in which the bottom flow path Q (see FIGS. 3 and 9) was blocked by the lower part of the outer peripheral wall part 41 by abutting the lower end of the outer peripheral wall part 41 against the placement surface (FL), but the present invention is not limited to this. For example, as shown in FIG. 10(a), a seat part 80 having a rounded rectangular plate shape and a flat upper surface seat surface 80a may be integrally provided on the lower end of the leg part 36 provided at the four corners of the bottom 13 so that the lower end of the outer peripheral wall part 41 and the seat surface 80a can abut against each other, and the bottom flow path Q may be blocked by the lower part of the outer peripheral wall part 41 by abutting the lower end of the outer peripheral wall part 41 against the seat surface 80a of the seat part 80 as shown in FIG. 10(b) to (a). According to another embodiment 1 shown in Figure 10, even if the mounting surface (FL) is uneven and rough, the lower end of the outer peripheral wall portion 41 can be abutted against the seat surface 80a without any gaps, so that the bottom flow path Q can be reliably blocked by the lower part of the outer peripheral wall portion 41.

[0056] (Alternative embodiment 2) FIG. 11 is an explanatory diagram of another embodiment 2. FIG. 11(a) shows a non-volatilization state, and FIG. 11(b) shows a maximum volatilization state in which the amount of volatilization of the drug volatilization device 1C is maximum. In the above embodiment, an example in which the external shape of the drug volatilization device 1A, 1B is formed into a square prism shape is shown, but this is not limited to this. For example, as in the drug volatilization device 1C shown in FIG. 11(a) and (b), the external shape may be formed into a cylindrical shape, and although explanation by illustration is omitted, the external shape may be a triangular prism, a polygonal prism having pentagons or more, an elliptical cylinder, etc. It is to be noted that, in the other embodiment 2 shown in FIG. 11, when a mechanism mainly composed of the lever member 75 adopted in the drug volatilization device 1B of the second embodiment is adopted, it goes without saying that the switching from the non-volatilization state to the maximum volatilization state can be performed by a one-touch operation (see FIG. 7(a)) by simply pressing the push button 72 with the index finger.
