Description

[Technical Field]

[0001] The present invention relates to a chemical volatilization device that volatilizes a volatile chemical such as an insect repellent. [Background technology]

[0002] A conventional drug volatilization device for volatilizing a volatile drug is disclosed in Patent Document 1. This drug volatilization device comprises a drug volatilization body that holds the volatile drug in a volatilizable manner, and a storage container that stores the drug volatilization body in a breathable manner. A plurality of openings are provided on the periphery of the storage container. The drug volatilized from the drug volatilization body is released to the outside through the openings. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-101180 A (pages 8 to 22, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0004] However, while the conventional chemical vaporization devices described above have excellent chemical diffusion properties because the volatile chemical is constantly released, further improvements have been required in terms of the sustainability of chemical vaporization performance. Also, even if the volatile chemical itself has no unpleasant odor and is highly safe, the volume of indoor spaces (toilets, bathrooms, bedrooms, living rooms, etc.), the inside of automobiles, tents, etc. is 2.0 to 33.3 m. 3 Some consumers are reluctant to constantly volatilize pesticides in small, enclosed spaces (including natural ventilation, 24-hour ventilation, etc.). For this reason, there is a demand for pesticide volatilization devices that can volatilize pesticides only when in use or for a certain period of time.

[0005] In this case, it is preferable that the device has a mechanism that allows easy switching between the volatilization state (when in use) and the non-volatilization state (when not in use). In particular, when switching between the volatilization state and the non-volatilization state frequently (for example, when switching between the volatilization state and the non-volatilization state at intervals of 12 hours or less), it is desirable for the device to be even simpler, but to date, no chemical volatilization device has been found that allows such switching with a relatively simple operation.

[0006] The present invention aims to provide a drug volatilization device that can be easily switched between a volatilization state (when in use) and a non-volatilization state (when not in use) with relatively simple operations, and that does not reduce the sustainability of drug volatilization performance. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention provides a drug volatilization device comprising a drug volatilizer that holds a volatile drug in a volatilizable manner, an outer container that covers the drug volatilizer, and a shutter arranged along the inner surface of the outer container, wherein when the outer container is switched between an upright position and an inverted position that is upside down compared to the upright position, the shutter descends under its own weight, and in one of the upright and inverted positions, the outer opening that opens on the circumferential surface of the outer container and the inner opening that opens on the shutter overlap, and in the other position, the inner opening is shifted vertically relative to the outer opening, and the outer opening is blocked by the periphery of the inner opening.

[0008] The present invention is also characterized in that in the drug volatilization device having the above-described configuration, a stopper is provided on the inner surface of the outer container to restrict the vertical movement of the shutter.

[0009] Furthermore, in the drug volatilization device of the present invention having the above-described configuration, the outer container has a front side member and a back side member that engage with each other, and an engaging claw is provided on one of the front side member and the back side member, and an engaged portion with which the engaging claw engages and an opposing wall that faces the engaged portion are provided on the other, and the opposing wall has a protrusion that faces the engaging claw that is inserted between the engaged portion and the opposing wall and is arranged forward in the insertion direction than the engaged portion.

[0010] Furthermore, in the chemical volatilization device of the present invention having the above-described configuration, the shutter and the outer container are colored in different exterior colors.

[0011] The present invention is also characterized in that, in the drug volatilization device of the above configuration, it is provided with an inner container that stores the drug volatilizer and is placed inside the outer container, the outer container being an injection-molded product and the inner container being a sheet-molded product. [Effects of the Invention]

[0012] According to the present invention, by allowing the user to alternately place the container in an upright position or an inverted position, the container can be easily switched between a volatilizing state with the outer opening open and a non-volatilizing state with the outer opening closed. By switching to the non-volatilizing state when not in use, the unnecessary volatilization of the volatile chemical can be suppressed, thereby maintaining the sustainability of the chemical volatilization performance.

DETAILED DESCRIPTION OF THE INVENTION

[0014] Embodiments of the present invention will be described below with reference to the drawings. Figures 1 and 2 show a perspective view and an exploded perspective view of one embodiment of a chemical volatilization device 1. The chemical volatilization device 1 releases a volatile chemical such as an insecticide or insect repellent to exterminate or repel flying pests such as mosquitoes.

[0015] The drug volatilization device 1 comprises a drug volatilizer 5, an outer container 20, and a shutter 40. The drug volatilizer 5 holds the volatile drug so that it can volatilize. The outer container 20 covers the drug volatilizer 5. The shutter 40 is arranged along the inner surface of the outer container 20. The drug volatilization device 1 is set upright on, for example, a table, and the volatile drug volatilized from the drug volatilizer 5 is released through an outer opening 20a that opens on the peripheral surface of the outer container 20.

[0016] The chemical volatilizer 5 can be configured to hold a volatile chemical so that it can volatilize by, for example, impregnation or kneading it in. Examples of materials for the chemical volatilizer 5 include paper, pulp, natural fibers, synthetic fibers, resin bodies, resin sheets, inorganic or organic porous bodies, gel bodies, etc.

[0017] Although the method of impregnating a resin sheet with a chemical is simple, it is preferable to use a resin body into which a volatile chemical has been kneaded, as this makes it easier to control the sustained release of the volatile chemical during use, stabilizes the amount of chemical that evaporates, and prevents the chemical from being washed away by moisture such as rain, but this is not particularly limited.

[0018] 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.

[0019] The form of the drug volatilizer 5 is not particularly limited and may be sheet-like, granular, three-dimensional, etc., but from the perspective 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.

[0020] The volatile agent may be an insecticide, repellent, antifungal agent, antibacterial agent, fragrance, deodorizer, synergist, or the like, 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, pyrethroid compounds that are volatile at room temperature, such as metofluthrin, profluthrin, empenthrin, and transfluthrin, which have high volatility and control effect against flying pests, are suitable. Furthermore, the volatile agent may be used in combination with a known, hardly volatile agent.

[0021] In this embodiment, the drug volatilizer 5 is contained in the inner container 10. For example, the inner container 10 is a sheet molded product of synthetic resin, and is composed of a front member 11 and a back member (not shown). The drug volatilizer 5 is sandwiched between the front member 11 and the back member. For example, the front member 11 and the back member may be connected at one end and folded in half to form the inner container 10.

[0022] The inner container 10 has a container flange 18, a container protrusion 19, a container opening 10a, and ribs 10b. The container flange 18 is arranged on the outer periphery of the inner container 10 and is formed in an annular shape. The container protrusion 19 is arranged along the inner periphery of the container flange 18 and is formed in an annular shape, protruding outward from both the front and back surfaces of the container flange 18. The provision of the container protrusion 19 improves the strength of the inner container 10. The container opening 10a is formed inside the container protrusion 19 and penetrates the inner container 10. The ribs 10b are formed in a lattice shape and their outer peripheries are connected to the container protrusion 19. This further improves the strength of the inner container 10. The volatile drug volatilizing from the drug volatilizer 5 flows out from the container opening 10a and is guided to the outer opening 20a of the outer container 20. The container protrusion 19 also has a pair of container convexities 19a. The container protrusions 19a are formed to protrude outward in the left-right direction from both side walls of the container protrusion 19, and are disposed in the center of the container protrusion 19 in the up-down direction (see FIG. 2).

[0023] The inner container 10 is inserted into the outer container 20 through an insertion hole 20c provided in the lower end surface thereof (see FIG. 2). This makes the inner container 10 detachable from the outer container 20, and the inner container 10 can be removed and the entire inner container 10 or the drug volatilizer 5 inside the inner container 10 can be easily replaced. However, it is also possible to design the inner container 10 so that it cannot be removed once attached.

[0024] The inner container 10 may be a resin molded product formed by injection molding, and the shape of the inner container 10 is not particularly limited as long as the container opening 10a is formed therein.

[0025] Fig. 3 is an exploded perspective view of the outer container 20, and Figs. 4 and 5 are perspective views showing a portion of the outer container 20. Fig. 4 shows the outer container 20 in an upright position, and Fig. 5 shows the outer container 20 in an inverted position. The inverted position is a position where the outer container 20 is upside down relative to the upright position. Fig. 6 is an enlarged perspective view showing a portion of the outer container 20.

[0026] The outer container 20 is a resin molded product formed by injection molding, and has a shutter 40 attached to it. The shutter 40 is a resin molded product formed in a plate shape. The shutters 40 are disposed on the inner surfaces of the front and rear sides of the outer container 20. The shutter 40 has multiple rectangular inner openings 40a opened by lattice-like bars 40b.

[0027] The outer container 20 is an injection-molded product made of synthetic resin, and has an insertion hole 20c opening on its bottom surface (see Figure 2). The inner container 10 is inserted into the outer container 20 through the insertion hole 20c. This allows the inner container 10 to be detachably attached to the outer container 20. A stopper 29 is provided in a protruding manner on the inner surface of the lower part of the outer container 20. An upper surface opening 20d, surrounded by a flange 23, opens on the top surface of the outer container 20 (see Figure 1).

[0028] Furthermore, when removing the inner container 10 from the outer container 20, the inner container 10 can be pushed out through the top opening 20d of the outer container 20.

[0029] The outer container 20 is composed of a front member 21 and a back member 22 that engage with each other. The front member 21 covers the front side of the inner container 10. The back member 22 covers the back side of the inner container 10. A plurality of rectangular outer openings 20a are opened on the periphery of the outer container 20 by lattice-like bars 20b. The outer openings 20a are formed to be approximately the same size as the inner openings 40a.

[0030] The front member 21 and the rear member 22 each have four protrusions 24 and four protrusion pieces 27 on their inner surfaces. The left-right spacing between the protrusions 24 is slightly larger than the left-right spacing on the outer surface of the shutter 40. The tips of the protrusions 24 are bent in the left-right direction so as to approach each other (see FIG. 6). A pair of protrusion pieces 27 is each disposed between the protrusions 24 lined up in the vertical direction.

[0031] The shutter 40 is disposed between the protrusions 24 arranged in the left-right direction. This allows the shutter 40 to be held on the inner surfaces of the front member 21 and the back member 22 so as to be slidable in the up-down direction. When the outer container 20 is in the upright position, the shutter 40 comes into contact with the stopper 29. This prevents the shutter 40 from coming off (see FIG. 4). When the outer container 20 is in the inverted position, the shutter 40 comes into contact with the flange 23. This prevents the shutter 40 from coming off (see FIG. 5).

[0032] When the inner container 10 is sandwiched in the front-rear direction between the front member 21 and the back member 22, the container protrusions 19a are disposed between the protruding pieces 27. When the outer container 20 is in an upright position or an inverted position, the container protrusions 19a come into contact with the protruding pieces 27. This prevents the inner container 10 from slipping off from the outer container 20. When the inner container 10 is inserted into the outer container 20 through an insertion hole 20c provided in the bottom end surface of the outer container 20 (see FIG. 2), the container protrusions 19a or the protruding pieces 27 elastically deform, and the container protrusions 19a climb over the protruding pieces 27. This allows the inner container 10 to be housed within the outer container 20.

[0033] The outer container 20 is made of, for example, white resin, and the shutter 40 is made of, for example, gray resin. The exterior colors of the outer container 20 and the shutter 40 do not matter and may be the same color, but if they are colored in different tones, the difference between the volatilizing state and the non-volatilizing state, which will be described later, can be easily seen.

[0034] 7 and 8 respectively show cross-sectional views of the upper and lower ends of the outer container 20 as viewed from below. A pair of left and right engaging claws 25a protruding rearward is provided at the upper end of the side surface of the front member 21 of the outer container 20, and a pair of left and right engaging claws 25b protruding rearward is provided at the lower end of the side surface. Furthermore, a pair of left and right ribs 26a is provided on the inner surface of the front member 21 inside the engaging claws 25a, and a pair of left and right ribs 26b is provided inside the engaging claws 25b.

[0035] Steps 28a and 29a are provided on the outer surface of the upper part of front side member 21 at the same positions in the left-right and up-down directions as engaging claw 25a and rib 26a, respectively. Steps 28b and 29b are provided on the outer surface of the lower part of front side member 21 at the same positions in the left-right and up-down directions as engaging claw 25b and rib 26b, respectively.

[0036] A pair of left and right engaged portions 30a that engage with the engaging claws 25a is provided at the upper end of the side surface of the back-side member 22, and a pair of left and right engaged portions 30b that engage with the engaging claws 25b is provided at the lower end of the side surface. In addition, a pair of left and right opposing walls 31a that face the engaged portions 30a is provided at the upper end of the back-side member 22, and a pair of left and right opposing walls 31b that face the engaged portions 30b is provided at the lower end. Step portions 33a, 33b are provided on the outer surface of the back-side member 22 at the same positions in the left-right and up-down directions as the opposing walls 31a, 31b, respectively.

[0037] Engaging claw 25a enters between engaged portion 30a and opposing wall 31a and engages with engaged portion 30a. At this time, opposing wall 31a enters between engaging claw 25a and rib 26a. Engaging claw 25b enters between engaged portion 30b and opposing wall 31b and engages with engaged portion 30a. At this time, opposing wall 31b enters between engaging claw 25b and rib 26b.

[0038] The width of the opposing wall 31b in the left-right direction is larger than the width of the opposing wall 31a in the left-right direction. Therefore, when the front member 21 is placed over the back member 22 with the top and bottom turned upside down, the opposing wall 31b abuts against the rib 26a, preventing the engagement of the engaging claws 25a. This prevents the front member 21 and the back member 22 from being erroneously attached.

[0039] The opposing wall 31a has a protrusion 32a that faces the engaging claw 25a and is disposed forward of the engaged portion 30a in the insertion direction. Therefore, the engaging claw 25a that moves between the engaged portion 30a and the opposing wall 31a is guided along the protrusion 32a by elastic deformation and engages with the engaged portion 30a.

[0040] Similarly, the opposing wall 31b has a protrusion 32b that faces the engaging claw 25b and is disposed forward of the engaged portion 30b in the insertion direction. Therefore, the engaging claw 25b moving between the engaged portion 30b and the opposing wall 31b is guided along the protrusion 32b by elastic deformation and engages with the engaged portion 30b. This causes the inner container 10 to be housed within the outer container 20.

[0041] The gap between the engaging claws 25a, 25b engaged with the engaged portions 30a, 30b and the opposing walls 31a, 31b is narrowed by the protrusions 32a, 32b, which prevents the disengagement of the front member 21 and the back member 22 due to an impact such as dropping the chemical volatilization device 1.

[0042] 9 and 10 are cross-sectional views showing the upper and lower portions of the stacked front side members 21 when assembling the outer container 20. The engagement claws 25a' and ribs 26a' of the stacked front side members 21' are disposed on the stepped portions 28a and 29a of the front side member 21. The engagement claws 25b' and ribs 26b' of the stacked front side members 21' are disposed on the stepped portions 28b and 29b of the front side member 21. This allows the front side members 21 to be stacked stably, improving the ease of assembly of the outer container 20.

[0043] 11 and 12 are cross-sectional views showing the upper and lower portions of the stacked rear members 22 when assembling the outer container 20. The facing wall 31a' of the stacked rear members 22' is disposed on the step portion 33a of the rear member 22. The facing wall 31b' of the stacked rear members 22' is disposed on the step portion 33b of the rear member 22. This allows the rear members 22 to be stably stacked, improving the ease of assembly of the outer container 20.

[0044] Alternatively, the front member 21 may be provided with the engaged portions 30a, 30b and the opposing walls 31a, 31b, and the rear member 12 may be provided with the engaging claws 25a, 25b and the ribs 26a, 26b.

[0045] Figure 13 shows a side cross-sectional view of the drug volatilization device 1 when the outer container 20 is in an upright position. Figure 14 shows a side cross-sectional view of the drug volatilization device 1 when the outer container 20 is in an inverted position. The shutter 40 is capable of moving up and down by its own weight within the outer container 20. Therefore, when in the upright position, the shutter 40 descends by its own weight, but its up and down movement is restricted by abutment with the stopper 29.

[0046] At this time, the inner opening 40a overlaps the outer opening 20a in the storage container 6, and the outer opening 20a is opened. As a result, the volatile drug volatilized from the drug volatilizer 5 is released into the space in which the drug volatilization device 1 is installed through the inner opening 40a and the outer opening 20a. In other words, the drug volatilization device 1 enters a volatilization state in which the volatile drug is volatilized to the outside.

[0047] Furthermore, when the storage container 6 is turned upside down from the upright position as indicated by arrow A, the shutter 40 descends under its own weight, but its vertical movement is restricted by the contact between the vertical end faces and the flange 23. At this time, the inner opening 40a is displaced vertically relative to the outer opening 20a, and the outer opening 20a is blocked by the crosspieces 40b around the inner opening 40a.

[0048] Therefore, the volatile drug volatilizing from the drug volatilizer 5 is blocked by the bars 40b around the inner opening 40a and the bars 20b around the outer opening 20a, preventing it from being released to the outside. In other words, the drug volatilization device 1 is in a non-volatilizing state where the volatilization of the volatile drug has stopped. This makes it possible to adjust the amount of drug used by placing it in an upright position when needed and in an inverted position when not needed, thereby maintaining the sustainability of the drug volatilization performance.

[0049] Furthermore, if the outer container 20 and the shutter 40 have different exterior colors, the bars 40b of the shutter 40, which have an exterior color different from that of the outer container 20, can be seen from the outer opening 20a, making it possible to recognize that the container is in a non-volatile state. Therefore, it is useful because it is easy to distinguish between the volatile state and the non-volatile state.

[0050] Although the inner opening 40a and the outer opening 20a are formed into a rectangle by the lattice-like bars 10b, 40b, they may have a shape other than a rectangle as long as the outer opening 20a can be blocked by the periphery of the inner opening 40a. Also, although the storage container 6 is in a volatilizing state when in the upright position and a non-volatilizing state when in the inverted position, it may also be in a non-volatilizing state when in the upright position and a volatilizing state when in the inverted position.

[0051] According to this embodiment, the user can alternately place the drug volatilization device 1 in an upright position or an inverted position, and easily switch between a volatilization state in which the outer opening 20a is open and a non-volatilization state in which the outer opening 20a is closed, i.e., on / off, which indicates when in use and when not in use. This allows the device to be switched to the non-volatilization state when not in use, thereby suppressing unnecessary volatilization of the volatile drug, and maintaining the sustainability of the drug volatilization performance.

[0052] Furthermore, the shutter 40 comes into contact with a stopper 29 provided on the inner surface of the outer container 20, thereby restricting the up and down movement of the shutter 40. Therefore, the inner opening 40a can be easily positioned relative to the outer opening 20a, and the container can be placed in a volatilizing or non-volatilizing state.

[0053] In addition, the opposing walls 31a, 31b facing the engaged portions 30a, 30b have protrusions 32a, 32b facing the engaging claws 25a, 25b and arranged forward of the engaged portions 30a, 30b in the insertion direction. This makes it possible to prevent disengagement between the front side member 21 and the back side member 22 due to impact caused by dropping the medicine volatilization device 1, etc.

[0054] Furthermore, since the inner container 10 and the outer container 20 are colored in different exterior colors, it is easy to distinguish between the volatilizing state and the non-volatilizing state.

[0055] Furthermore, since the inner container 10 is a sheet-formed product, the manufacturing costs of the medicine volatilization device 1 can be reduced. [Industrial Applicability]

[0056] The present invention can be used in a chemical volatilization device that volatilizes volatile chemicals such as insecticides, repellents, antifungal agents, antibacterial agents, fragrances, deodorants, and synergists. [Explanation of symbols]
