AI Technical Summary
Chemical volatilizers for screen doors attached with hook-and-loop fasteners can flap and detach due to wind, causing the pesticide volatilizer to fall when a strong wind blows, as the thickness of the fastener creates a gap between the container and the screen door.
The chemical volatilizer is designed with a hook-and-loop fastener fixing surface offset from the container's periphery, a peripheral portion that contacts the screen door, and a configuration that ensures the peripheral portion is pressed against the screen door, reducing the gap and enhancing stability.
This design prevents the chemical volatilizer from flapping and detaching, ensuring stability even in strong winds by minimizing the gap between the container and the screen door, thus maintaining attachment.

Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a chemical volatilizer for screen doors that is attached to screen doors. [Background technology]
[0002] For example, as disclosed in Patent Documents 1 and 2, chemical volatilization devices that can be attached to screen doors of homes and the like are known. This type of chemical volatilization device includes an impregnated body impregnated with a chemical such as a pest repellent, and a container that houses the impregnated body. The container has multiple openings for allowing air to circulate, and is equipped with a hook-and-loop fastener for fastening the container to the screen door. When this chemical volatilization device is attached to the screen door, the chemical impregnated in the impregnated body is diffused into the surrounding area when the wind blows, thereby preventing pests from approaching the vicinity of the window, for example. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Design Registration No. 1449797 [Patent Document 2] Design Registration No. 1585758 Summary of the Invention [Problem to be solved by the invention]
[0004] When attaching such a chemical volatilizer for screen doors to a screen door using hook-and-loop fasteners, the screen door is sandwiched between one hook-and-loop fastener fixed to the chemical volatilizer and the other hook-and-loop fastener that engages with the first hook-and-loop fastener, thereby securing the chemical volatilizer to the screen door.
[0005] However, because the hook-and-loop fastener itself has thickness, when a pesticide volatilizer is attached to a screen door as described above, the periphery of the container of the pesticide volatilizer may rise from the screen door by the thickness of the hook-and-loop fastener, and a gap may occur between the periphery of the container and the screen door. The inventors' research has revealed that when a strong wind blows with such a gap, the pesticide volatilizer will be blown around by the wind and will flap.
[0006] If this flapping occurs repeatedly, the hook-and-loop fastener may come off the screen door, causing the pesticide vaporizer to fall.
[0007] The present disclosure has been made in consideration of these points, and its purpose is to suppress the flapping of chemical volatilizers for screen doors. [Means for solving the problem]
[0008] To achieve the above object, a first aspect of the present disclosure is a chemical volatilizer for screen doors that is attached to a screen door with a hook-and-loop fastener having fastener components on one side and the other that engage with each other. The chemical volatilizer for screen doors comprises a chemical holder that holds a volatile chemical, and a container that houses the chemical holder. The side of the container facing the screen door has a hook-and-loop fastener fixing surface to which the fastener component on one side is fixed, and a peripheral portion that is formed around the hook-and-loop fastener fixing surface and comes into contact with the screen door. The hook-and-loop fastener fixing surface is offset a predetermined distance from the peripheral portion in a direction away from the screen door.
[0009] With this configuration, the hook-and-loop fastener fixing surface to which the fastener component on one side is fixed is offset in a direction away from the screen door relative to the periphery of the container, so that when the screen door chemical volatilizer is attached to the screen door, the gap between the periphery and the screen door is reduced, preventing the screen door chemical volatilizer from flapping.
[0010] In the second aspect of the present disclosure, the predetermined dimension can be set to be longer than the thickness of the fastener component member on the one side.
[0011] With this configuration, when the fastener components on one side and the other side are engaged with each other and the screen door is sandwiched between the fastener components, the peripheral portion is pressed against the screen door, which ensures that the peripheral portion comes into contact with the screen door, further enhancing the effect of suppressing flapping.
[0012] In a third aspect of the present disclosure, the hook-and-loop fastener fixing surface can be configured as a flat surface, and the peripheral portion can be formed so as to extend in a direction parallel to the hook-and-loop fastener fixing surface.
[0013] With this configuration, when the chemical volatilizer for screen doors is attached to the screen door, a wide area of the periphery is pressed against the screen door, making the chemical volatilizer for screen doors stable.
[0014] The container according to the fourth aspect of the present disclosure is formed to extend vertically along the screen door, the hook-and-loop fastener fixing surface is located in the vertical middle of the container, and the peripheral portion is located above and below the hook-and-loop fastener fixing surface.
[0015] With this configuration, the peripheral portion is spaced apart from the hook-and-loop fastener fixing surface in both the vertical and horizontal directions, making the chemical volatilizer for screen doors even more stable.
[0016] The container according to the fifth aspect of the present disclosure is formed to extend in the left-right direction along the screen door, the hook-and-loop fastener fixing surface is located in the middle of the container in the left-right direction, and the peripheral portion is located away from the hook-and-loop fastener fixing surface in both the left and right directions.
[0017] With this configuration, the peripheral portion is spaced apart on both the left and right sides from the hook-and-loop fastener fixing surface, making the chemical volatilizer for screen doors even more stable.
[0018] In a sixth aspect of the present disclosure, a vent is formed between the hook-and-loop fastener fixing surface and the peripheral portion of the container. With this configuration, a vent with a large opening area can be obtained by utilizing the portion between the hook-and-loop fastener fixing surface and the peripheral portion, thereby increasing the efficiency of volatilization of the drug held in the drug holder.
[0019] In a seventh aspect of the present disclosure, a peripheral wall portion extending in a direction approaching the screen door is formed on the outer periphery of the container, and the peripheral portion is composed of an extending plate portion extending from the end of the peripheral wall portion in a direction along the screen door.
[0020] With this configuration, the peripheral wall and the extension plate are formed on the outer periphery of the container, which increases the rigidity of the container. Furthermore, the extension plate is particularly resistant to deformation, and this resistant portion forms the periphery and is pressed against the screen door, further increasing the effect of suppressing flapping of the container.
[0021] In an eighth aspect of the present disclosure, there is no portion that comes into contact with the screen door between the hook-and-loop fastener fixing surface and the extension plate portion.
[0022] With this configuration, no unnecessary tension is applied to the screen between the hook-and-loop fastener fixing surface and the extension plate portion, making it difficult for the hook-and-loop fastener to disengage. [Effects of the Invention]
[0023] As explained above, the hook-and-loop fastener fixing surface is offset away from the screen door relative to the periphery of the container, thereby reducing the gap between the periphery and the screen door, thereby preventing the screen door chemical volatilizer from flapping.

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.
[0026] FIG. 1 is a perspective view of a screen door chemical volatilizer 1 according to an embodiment of the present invention attached to a screen door 100, as viewed from the front. While only a portion of the screen portion of the screen door 100 is shown in this figure, the screen door 100 is attached to a window frame in, for example, a home, office, store, or workshop. The screen door 100 may be fixed or retractable. In this embodiment, the up-down direction, left-right direction, and front-to-back direction of the screen door 100 are defined as shown in each figure, but this is for ease of explanation. The left-right direction of the screen door 100 is the same as the left-to-right direction when facing the screen door 100. For example, in the case of a sliding screen door 100, the opening and closing direction corresponds to the left-to-right direction. The left-to-right direction of the screen door chemical volatilizer 1 corresponds to the left-to-right direction of the screen door 100, and the up-to-down direction of the screen door chemical volatilizer 1 corresponds to the up-to-down direction of the screen door 100.
[0027] Although not shown, a typical screen door 100 comprises a frame that is attached to a window frame or the like, and a mesh stretched over the frame. As shown in the figure, the mesh is made up of, for example, a number of warp threads extending vertically and a number of weft threads extending horizontally, but the direction in which the threads extend may also be diagonal. Furthermore, the thickness of the threads and the spacing between adjacent threads can be set as desired, and the screen door 100 shown in the figure is merely one example.
[0028] The screen door chemical volatilizer 1 is a device attached to a screen door 100 using hook-and-loop fasteners 40 shown in FIG. 2 and includes a chemical carrier 2 holding a volatile chemical and a container 10 for containing the chemical carrier 2. The chemical carrier 2 is plate-shaped, extending vertically and horizontally, and is breathable, allowing air to pass through from front to back. The chemical carrier 2 has numerous holes 2a formed therethrough. The chemical carrier 2 is made of, for example, woven fabric and is capable of holding various chemicals. Examples of chemicals include pest repellents, insecticides, fragrances, disinfectants, and deodorizers. Any one of these chemicals may be held by the chemical carrier 2 alone, or a mixture of two or more chemicals may be held by the chemical carrier 2. The chemical carrier 2 may be held by coating or spraying the chemical carrier 2. Furthermore, when the drug support 2 is a woven fabric made of synthetic fibers, the drug may be held by kneading it into the synthetic fibers. The drug support 2 may also be made of a resin molded body. In this case, the drug can be held by kneading it into the resin that makes up the drug-impregnated body. The drug support 2 may also be, for example, a nonwoven fabric, a net, a mat, a sponge, etc. In the case of a nonwoven fabric, a woven fabric, or a net, air is allowed to pass through the fibers.
[0029] As shown in Figures 3 to 7, the container 10 is a flat plate extending along the screen door 100, and is shaped so that when attached to the screen door 100, it does not protrude significantly in the front-to-back direction from the screen door 100. In this embodiment, a case where a screen door chemical volatilizer 1 is attached to the outdoor side of the screen door 100 is described. As will be described later, the container 10 of this embodiment has wind-receiving plates 27, 28 on its front side, and by attaching the screen door chemical volatilizer 1 with the wind-receiving plates 27, 28 facing the outdoor side, it is possible to take in the wind blowing outdoors and efficiently diffuse the chemical. However, the screen door chemical volatilizer 1 can also be attached to the indoor side of the screen door 100 for use.
[0030] The container 10 has a top container component 20 and a bottom container component 30 formed by molding a resin sheet. The resin sheet is made of a hard resin, and the hard resin is not particularly limited, but examples thereof include polyethylene terephthalate and polyethylene. The top container component 20 and the bottom container component 30 can be obtained by vacuum forming or pressure forming the resin sheet using a molding machine (not shown). Conventional well-known methods can be used for vacuum forming and pressure forming. In addition, when obtaining the top container component 20 and the bottom container component 30, unnecessary portions are trimmed.
[0031] Since the chemical volatilizer 1 for screen doors is required to be thin and lightweight in order to be attached to the screen door 100, it is preferable that it be made by molding a resin sheet as described above, but this is not limiting and it may be molded by other methods such as resin injection molding. Also, the front container component 20 and the back container component 30 may be molded by different molding methods.
[0032] 5 to 7, etc., the drug support 2 is held inside the container 10 in a state where it is sandwiched between the front-side container component 20 and the back-side container component 30 in the front-back direction. The shape of the drug support 2 can be, for example, rectangular, but is not limited to this, and may be any plate-like shape that can be accommodated inside the container 10 and corresponds to the shape of the container 10.
[0033] The container 10 has a rectangular shape or a shape that can approximate a rectangle when viewed from the front and back. In this case, the rectangle may be a square, a rectangle that is longer in the vertical direction, a rectangle that is longer in the horizontal direction, a diamond, a trapezoid, etc. The shape of the container 10 may also be a shape other than a rectangle or a shape that can approximate a rectangle, such as a triangle, a polygon with pentagons or more sides, a circle, an ellipse, etc.
[0034] The front-side container component 20 is a component that constitutes the front side of the container 10, and the back-side container component 30 is a component that constitutes the back side of the container 10. The container 10 is formed by combining the front-side container component 20 and the back-side container component 30. The front-side container component 20 and the back-side container component 30 may be integrated, for example, by a fitting structure, or by engaging an engaging claw with a mating component, or by bonding, welding, or the like.
[0035] The front-side container component 20 and the back-side container component 30 may be integrally molded. For example, the container 10 can be constructed by molding a member in which the front-side container component 20 and the back-side container component 30 are connected from a single resin sheet, and then bending the connection between the front-side container component 20 and the back-side container component 30 by 180 degrees.
[0036] The outer shape of the front-side container component 20 and the outer shape of the back-side container component 30 are substantially the same. When the container 10 is viewed from the front side, most of the back-side container component 30 is not visible, and when the container 10 is viewed from the back side, most of the front-side container component 20 is not visible. Note that the outer shapes of the front-side container component 20 and the back-side container component 30 do not have to be the same, and one may be formed larger than the other.
[0037] (Regarding the components of the front container) 1 and 3, a left vent hole (first vent hole) 21 is formed to the left of the center in the left-right direction of the front container component 20. A right vent hole (second vent hole) 22 is formed to the right of the center in the left-right direction of the front container component 20. When forming the left vent hole 21 and the right vent hole 22, the resin sheet is trimmed with a trimming device or the like. Other vent holes, which will be described later, can be formed in the same manner.
[0038] The left-side ventilation opening 21 and the right-side ventilation opening 22 are spaced apart in the left-right direction and are both elongated in the up-down direction. The edges of the left-side ventilation opening 21 that extend in the up-down direction are the left edge and the right edge, and the edges of the right-side ventilation opening 22 that extend in the up-down direction are the left edge and the right edge. The left edge of the left-side ventilation opening 21 is located near the left end of the front-side container component 20. The right edge of the right-side ventilation opening 22 is located near the right end of the front-side container component 20.
[0039] The right edge of the left vent 21 is formed so that the vertically intermediate portion is located at the rightmost position and is positioned further to the left as it approaches the upper and lower ends. The left edge of the right vent 22 is formed so that the vertically intermediate portion is located at the leftmost position and is positioned further to the right as it approaches the upper and lower ends. A plate portion 25 extending in the vertical and left-right directions is formed between the vertically intermediate portion of the left vent 21 and the vertically intermediate portion of the right vent 22. No vents are formed in this plate portion 25. Note that this plate portion 25 is provided to correspond to a hook-and-loop fastener fixing surface 35 (described below) of the rear container component 30.
[0040] An upper vent (third vent) 23 is formed between the left vent 21 and the right vent 22 above the plate portion 25 of the front-side container component 20. A lower vent (third vent) 24 is formed between the left vent 21 and the right vent 22 below the plate portion 25 of the front-side container component 20. The upper vent 23 and the lower vent 24 are spaced apart in the vertical direction, and the plate portion 25 is formed between the upper vent 23 and the lower vent 24. Both the upper vent 23 and the lower vent 24 are formed long in the horizontal direction. The upper edge of the upper vent 23 is located near the upper end of the front-side container component 20. The lower edge of the lower vent 24 is located near the lower end of the front-side container component 20.
[0041] The lower edge of the upper ventilation port 23 is formed so that the middle part in the left-right direction is located at the lowest position and the positions increase toward the left and right ends. The upper edge of the lower ventilation port 24 is formed so that the middle part in the up-down direction is located at the highest position and the positions decrease toward the left and right ends. In addition, four small-diameter openings 26 are formed around the periphery of the plate portion 25 of the front-side container component 20.
[0042] The front container component 20 has a left-side wind receiving plate portion (first wind receiving plate portion) 27 that protrudes from the right edge of the left-side ventilation port 21 toward the front side (outside the thickness direction of the container 10), and a right-side wind receiving plate portion (second wind receiving plate portion) 28 that protrudes from the left edge of the right-side ventilation port 22 toward the front side (outside the thickness direction of the container 10).
[0043] The left-side wind receiving plate 27 is formed long in the vertical direction along the right edge of the left-side ventilation port 21, with the upper end of the left-side wind receiving plate 27 located near the upper end of the front-side container component 20 and the lower end of the left-side wind receiving plate 27 located near the lower end of the front-side container component 20. Because of this configuration, the left-side wind receiving plate 27 also serves as a connecting portion that connects the vicinity of the upper left edge of the front-side container component 20 with the upper left edge of the plate 25. The left-side wind receiving plate 27 also serves as a connecting portion that connects the vicinity of the lower left edge of the front-side container component 20 with the lower left edge of the plate 25.
[0044] 5 and 6, left-side wind receiving plate portion 27 is formed to be inclined or curved so that it is positioned further to the left as it approaches the tip of the protruding direction, and is positioned so as to face the surface of drug holder 2. The distance between left-side wind receiving plate portion 27 and the surface of drug holder 2 becomes longer as it approaches the tip of left-side wind receiving plate portion 27 in the protruding direction.
[0045] The tip of the left-side wind receiving plate 27 in the protruding direction has a first bent portion 27a bent so as to be approximately parallel to the surface of the drug holder 2. That is, the tip of the left-side wind receiving plate 27 in the protruding direction has the first bent portion 27a bent to the left and extending in the vertical direction, and arranged so as to face the surface of the drug holder 2. By bending the first bent portion 27a to the left, it becomes possible to distinguish the portion of the left-side wind receiving plate 27 other than the first bent portion 27a (main body portion) from the first bent portion 27a. The main body portion of the left-side wind receiving plate 27 is inclined at a predetermined angle with respect to the surface of the drug holder 2. The first bent portion 27a is bent in the opposite direction to the plate portion 25.
[0046] As shown in FIG. 1 , first through holes 27b are formed in the left-side wind receiving plate 27. In this embodiment, three first through holes 27b are formed, but the number of first through holes 27b is not limited to this, and may be one, two, or four or more. The three first through holes 27b are formed spaced apart from one another in the vertical direction, and first through holes 27b are formed in the upper portion, the vertical middle portion, and the lower portion of the left-side wind receiving plate 27. Although the first through holes 27b have a shape that is elongated in the vertical direction, the shape is not limited to this, and may be square, circular, or other shapes.
[0047] The right-side wind receiving plate 28 is formed long in the vertical direction along the left edge of the right-side air vent 22, with the upper end of the right-side wind receiving plate 28 located near the upper end of the front-side container component 20 and the lower end of the right-side wind receiving plate 28 located near the lower end of the front-side container component 20. Because of this configuration, the right-side wind receiving plate 28 also serves as a connecting portion that connects the vicinity of the upper right edge of the front-side container component 20 with the upper right edge of the plate 25. The right-side wind receiving plate 28 also serves as a connecting portion that connects the vicinity of the lower right edge of the front-side container component 20 with the lower right edge of the plate 25.
[0048] 5 and 6, right-side wind receiving plate 28 is formed to be inclined or curved so that it is positioned further to the right as it approaches the tip of the protruding direction, and is positioned so as to face the surface of chemical holder 2. The distance between right-side wind receiving plate 28 and the surface of chemical holder 2 becomes longer as it approaches the tip of right-side wind receiving plate 28 in the protruding direction.
[0049] As shown in FIGS. 5 and 6 , the protruding tip of the right-side wind receiving plate 28 has a second bent portion 28a bent to be approximately parallel to the surface of the chemical carrier 2. That is, the protruding tip of the right-side wind receiving plate 28 has the second bent portion 28a bent to the right and extending in the vertical direction, positioned directly opposite the surface of the chemical carrier 2. By bending the second bent portion 28a to the right, the portion of the right-side wind receiving plate 28 other than the second bent portion 28a (main body portion) can be distinguished from the second bent portion 28a. The main body portion of the right-side wind receiving plate 28 is inclined at a predetermined angle relative to the surface of the chemical carrier 2, and the inclination direction of the main body portion of the right-side wind receiving plate 28 is opposite the inclination direction of the main body portion of the left-side wind receiving plate 27. Furthermore, the second bent portion 28a is bent in the opposite direction to the plate portion 25.
[0050] As shown in FIG. 3 , second through holes 28b are formed in the right-side wind receiving plate 28. In this embodiment, three second through holes 28b are formed, but the number of second through holes 28b is not limited to this, and may be one, two, or four or more. The three second through holes 28b are formed spaced apart from one another in the vertical direction, and the second through holes 28b are formed in the upper portion, the vertical middle portion, and the lower portion of the right-side wind receiving plate 28. The second through holes 28b have a vertically elongated shape, but are not limited to this, and may be square, circular, or other shapes. The first through holes 27b and the second through holes 28b may have the same shape and the same number, or may have different shapes and different numbers.
[0051] 5 and 6, a front-side peripheral wall portion 20a is formed on the outer periphery of the front-side container component 20, extending in the direction approaching the screen door 100 (toward the back side). The front-side peripheral wall portion 20a is continuous in the circumferential direction of the front-side container component 20. A front-side extending plate portion 20b extending in the direction along the screen door 100 is continuous with the end of the front-side peripheral wall portion 20a.
[0052] (Effect of the wind receiving plate) In the chemical volatilization device 1 for screen doors of this embodiment, the left wind receiving plate portion 27 and the right wind receiving plate portion 28 each have a first bent portion 27a and a second bent portion 28a, which increases the rigidity of the front container component 20 and, ultimately, the rigidity of the container 10.
[0053] Furthermore, the front side of container 10 is provided with left and right wind receiving plates 27 and 28 that protrude outward from container 10, allowing wind to be taken into container 10 from the front side. At this time, left and right wind receiving plates 27 and 28 have first and second bent portions 27a and 28a, respectively, so wind from the direction in which first bent portion 27a and second bent portion 28a are oriented can easily enter container 10. Therefore, even if wind receiving plates 27 and 28 do not protrude significantly in the thickness direction of container 10, wind can be efficiently taken into container 10 and directed at drug holder 2.
[0054] Furthermore, because the left wind receiving plate 27 and the right wind receiving plate 28 are long in the vertical direction, a large amount of wind blowing from the left or right side can be taken into the interior of the container 10, thereby increasing the amount of wind hitting the drug holder 2. Furthermore, if the first bent portion 27a and the second bent portion are oriented opposite to each other, the wind can be received and guided to the drug holder 2 regardless of whether it is blowing from the left or right direction.
[0055] 11A, because through-hole 27b is provided in left-side wind receiving plate 27, when the wind blows from the right, the wind is not completely blocked by left-side wind receiving plate 27. Also, as shown in FIG. 11B, because through-hole 28b is provided in right-side wind receiving plate 28, when the wind blows from the left, the wind is not completely blocked by right-side wind receiving plate 28. Therefore, the medicine can be diffused efficiently regardless of the wind direction.
[0056] (Regarding rear container components) A left-side ventilation port 31 is formed to the left of the center in the left-right direction of the rear-side container component 30. A right-side ventilation port 32 is formed to the right of the center in the left-right direction of the rear-side container component 30. The left-side ventilation port 31 and the right-side ventilation port 32 are spaced apart from each other in the left-right direction and are both long in the up-down direction. The left-side ventilation port 31 of the rear-side container component 30 and the left-side ventilation port 21 of the front-side container component 20 overlap in the front-back direction. Furthermore, the right-side ventilation port 32 of the rear-side container component 30 and the right-side ventilation port 22 of the front-side container component 20 overlap in the front-back direction.
[0057] The right edge of the left vent hole 31 of the rear container component 30 is formed so that the vertical middle portion is located at the rightmost position and is positioned further left as it approaches the upper and lower ends. The left edge of the right vent hole 32 of the rear container component 30 is formed so that the vertical middle portion is located at the leftmost position and is positioned further right as it approaches the upper and lower ends. A hook-and-loop fastener fixing surface 35 consisting of a flat surface extending in the vertical and left-right directions is formed between the vertical middle portion of the left vent hole 31 of the rear container component 30 and the vertical middle portion of the right vent hole 32.
[0058] The hook and loop fastener fixing surface 35 is located in the vertical middle of the container 10 and also in the horizontal middle of the container 10. No ventilation hole is formed in the hook and loop fastener fixing surface 35. Since the rear container component 30 is located on the side of the container 10 facing the screen door 100, the hook and loop fastener fixing surface 35 is formed on the side of the container 10 facing the screen door 100. The hook and loop fastener fixing surface 35 of the rear container component 30 and the plate portion 25 of the front container component 20 overlap in the front-to-back direction.
[0059] 2 and 9, hook and loop fastener 40 has one fastener-component member 41 and another fastener-component member 42 that engage with each other. One of one fastener-component member 41 and another fastener-component member 42 is a loop side having many loops, and the other is a hook side having many hooks that engage with the loops. Note that one fastener-component member 41 may be provided with both loops and hooks, and the other fastener-component member 42 may also be provided with both loops and hooks. The shapes of the hooks and loops can be set as desired.
[0060] One-side fastener component member 41 and the other-side fastener component member 42 are formed in the same rectangular shape and are smaller than hook-and-loop fastener fixing surface 35. One-side fastener component member 41 is fixed to hook-and-loop fastener fixing surface 35. For example, one-side fastener component member 41 can be fixed to hook-and-loop fastener fixing surface 35 using double-sided adhesive tape, adhesive, or the like. Hook-and-loop fastener fixing surface 35 and one-side fastener component member 41 may be the same size.
[0061] An upper vent 33 is formed between the left vent 31 and the right vent 32 above the hook-and-loop fastener fixing surface 35 of the rear container component 30. A lower vent 34 is formed between the left vent 31 and the right vent 32 below the hook-and-loop fastener fixing surface 35 of the rear container component 30. The upper vent 33 and the lower vent 34 are spaced apart from each other in the vertical direction, and the hook-and-loop fastener fixing surface 35 is formed between the upper vent 33 and the lower vent 34. Both the upper vent 33 and the lower vent 34 are formed long in the horizontal direction. The upper edge of the upper vent 33 is located near the upper end of the rear container component 30. The lower edge of the lower vent 34 is located near the lower end of the rear container component 30. The upper ventilation port 33 of the rear-side container component 30 and the upper ventilation port 23 of the front-side container component 20 overlap in the front-back direction. Also, the lower ventilation port 34 of the rear-side container component 30 and the lower ventilation port 24 of the front-side container component 20 overlap in the front-back direction.
[0062] The lower edge of the upper ventilation opening 33 of the rear container component 30 is formed so that the middle part in the left-right direction is located at the lowest position and the positions become higher toward the left and right ends. The upper edge of the lower ventilation opening 34 is formed so that the middle part in the up-down direction is located at the highest position and the positions become lower toward the left and right ends.
[0063] A rear peripheral wall portion 30a is formed on the outer periphery of the rear container component 30, extending in a direction approaching the screen door 100. The rear peripheral wall portion 30a is continuous in the circumferential direction of the rear container component 30. The rear peripheral wall portion 30a is arranged so as to overlap the inside of the front peripheral wall portion 20a. A rear extending plate portion 30b extending in a direction along the screen door 100 is continuous with the end of the rear peripheral wall portion 30a. The rear extending plate portion 30b is arranged so as to overlap the back side of the front extending plate portion 20b.
[0064] The rear extension plate portion 30b is formed around the hook-and-loop fastener fixing surface 35 and is the portion (peripheral portion) that contacts the screen door 100. In this embodiment, the rear extension plate portion 30b forms a ring shape that continues in the circumferential direction of the rear container component 30, and has a left side portion 30c, a right side portion 30d, an upper side portion 30e, and a lower side portion 30f. The left side portion 30c and the right side portion 30d are provided spaced apart from the hook-and-loop fastener fixing surface 35 to the left and right, respectively. The upper side portion 30e and the lower side portion 30f are provided spaced apart from the hook-and-loop fastener fixing surface 35 to the upper and lower, respectively.
[0065] The left side 30c and the right side 30d extend in the vertical direction. The top side 30e and the bottom side 30f extend in the horizontal direction. The top ends of the left side 30c and the right side 30d are connected to the left and right ends of the top side 30e, respectively. The bottom ends of the left side 30c and the right side 30d are connected to the left and right ends of the bottom side 30f, respectively.
[0066] The rear-side extending plate portion 30b is formed to extend in a direction parallel to the hook-and-loop fastener fixing surface 35. Furthermore, a left-side vent 31, a right-side vent 32, an upper-side vent 33, and a lower-side vent 34 are formed between the hook-and-loop fastener fixing surface 35 and the rear-side extending plate portion 30b in the container 10. This allows air to pass in the front-to-back direction by utilizing the area between the hook-and-loop fastener fixing surface 35 and the rear-side extending plate portion 30b.
[0067] As shown in Fig. 9, the hook-and-loop fastener fixing surface 35 is offset by a predetermined distance C from the rear-side extending plate portion 30b in a direction away from the screen door 100. C is a positive value. That is, Fig. 9 shows the non-attached state, and in this non-attached state, when a first imaginary plane 200 passing through the hook-and-loop fastener fixing surface 35 and a second imaginary plane 201 passing through the back surface of the rear-side extending plate portion 30b are imagined, the position of the hook-and-loop fastener fixing surface 35 in the front-and-back direction relative to the rear-side extending plate portion 30b is set so that the distance between the first imaginary plane 200 and the second imaginary plane 201 is the predetermined distance C. In other words, the position of the rear-side extending plate portion 30b in the front-and-back direction relative to the hook-and-loop fastener fixing surface 35 is set so as to achieve the predetermined distance C.
[0068] The predetermined dimension C is set to be longer than the thickness of the one-side fastener component 41. Specifically, it is set to be 0.3 mm or more, or 1.0 mm or more. This allows the rear extension plate portion 30b to be reliably in contact with the screen door 100 when attached to the screen door 100, as shown in FIG. 10 . If the predetermined dimension C is less than 0.3 mm, there is a risk that the rear extension plate portion 30b will not be reliably in contact with the screen door 100 when taking into account molding errors, etc. However, by setting the predetermined dimension C to be 0.3 mm or more, the rear extension plate portion 30b can be reliably in contact with the screen door 100 even if molding errors, etc. occur. Furthermore, by setting the predetermined dimension C to be 1.0 mm or more, the rear extension plate portion 30b can be pressed against the screen door 100 even if molding errors, etc. occur.
[0069] The upper limit of the predetermined dimension C is 15 mm or less, and can be 10 mm or less. If the predetermined dimension C exceeds 15 mm, it will be necessary to press the rear extension plate portion 30b strongly against the screen door 100, and the reaction force may cause the hook-and-loop fastener 40 to disengage. Furthermore, depending on the engagement force of the hook-and-loop fastener 40, it is possible that the hook-and-loop fastener 40 will disengage if the predetermined dimension C exceeds 10 mm. Therefore, it is preferable to set an upper limit for the predetermined dimension C.
[0070] Furthermore, it is preferable that the rear container component 30 does not have a portion that comes into contact with the screen door 100 (a portion that protrudes toward the screen door 100) between the hook-and-loop fastener fixing surface 35 and the rear extension plate portion 30b. If there were a portion that came into contact with the screen door 100, unnecessary tension would be applied to the screen door 100 between the hook-and-loop fastener fixing surface 35 and the rear extension plate portion 30b, which would make it easier for the hook-and-loop fastener 40 to disengage.
[0071] (Effects of the embodiment) When attaching to screen door 100, one side fastener component 41 is fixed to hook-and-loop fastener fixing surface 35 on the back side of container 10, so by placing the other side fastener component 42 on the back side of screen door 100 and pressing it against one side fastener component 41 while this one side fastener component 41 is pressed against the front side of screen door 100, both fastener components 41, 42 will engage with each other as shown in Figure 10, making it possible to attach and use screen door chemical volatilizer 1 to screen door 100. Note that it is also possible to press one side fastener component 41 against the back side of screen door 100 and place the other side fastener component 42 on the front side of screen door 100 and press it against one side fastener component 41, thereby engaging both fastener components 41, 42 with each other.
[0072] Because hook-and-loop fastener fixing surface 35 to which one-side fastener component 41 is fixed is offset away from screen door 100 relative to rear extension plate 30b of container 10, when screen door chemical volatilizer 1 is attached to screen door 100, the gap between rear extension plate 30b and screen door 100 is small. In particular, in this embodiment, the predetermined offset dimension C is set to be longer than the thickness of one-side fastener component 41, so when screen door chemical volatilizer 1 is attached to screen door 100, the gap between rear extension plate 30b and screen door 100 can be reliably reduced to zero, as shown in Figure 10. In other words, screen door chemical volatilizer 1 can be attached to screen door 100 with rear extension plate 30b pressed against screen door 100. As a result, the rear extension plate portion 30b is supported by the screen door 100, so flapping of the chemical volatilizer 1 for screen doors is suppressed even when a strong wind blows.
[0073] The above configuration prevents the engagement between one-side fastener component 41 and the other-side fastener component 42 from gradually loosening due to flapping in strong winds. Therefore, even in an environment with strong winds, it is possible to prevent the other-side fastener component 42 from coming off and causing the chemical volatilizer for screen doors 1 to fall off the screen door 100.
[0074] The above-described embodiments are merely examples in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. [Industrial Applicability]
[0075] As explained above, the chemical volatilizing device for screen doors according to the present invention can be used by attaching it to a screen door of a house or the like. [Explanation of symbols]
