Description

[Technical Field]

[0001] The present invention relates to a pest trap. [Background technology]

[0002] In the agricultural field, various pest traps have been proposed to protect plants such as vegetables and fruits, or livestock such as cows, from pests. Generally, pest traps using adhesive tape or the like are widely used for pest control. Patent Document 1 discloses a pest trap that has a pest trapping section that stands upright from the ground and further has an adhesive layer with its lower end positioned close to the ground. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-80300 Summary of the Invention [Problem to be solved by the invention]

[0004] However, pest traps that use adhesive, such as the pest trap disclosed in Patent Document 1, can adhere to the operator when setting up the pest trap, so care must be taken when handling them. Also, once the adhesive adheres, it is difficult to remove, making them difficult to handle. Furthermore, when placed in fields where vegetables or fruits are planted or in cowsheds, the adhesive can adhere to the vegetables, fruits, or livestock such as cows, reducing their commercial value and causing stress to the livestock, among other issues.

[0005] It is also known that adhesion of moisture, dust, etc. to adhesives used to capture pests can reduce the adhesive performance and strength.

[0006] To provide a pest trap which can trap pests without using an adhesive, is easy to handle, and does not deteriorate in trapping ability. [Means for solving the problem]

[0007] The pest trap of the present invention is a pest trap for capturing pests, comprising: a lower container part having a fitting receiving part and a pocket part for capturing pests; and an upper lid having a fitting part for fitting into the fitting receiving part of the lower container part, the upper lid being detachably fitted to the lower container part by fitting the fitting part into the fitting receiving part. The upper lid has a bottom part connected to the inside of the periphery of the fitting part and extending inside the upper lid, and a lid part connected to a part of the bottom part and provided so as to be able to open and close vertically, and a through hole is provided between the lid part and the bottom part at a position opposite the connection part between the lid part and the bottom part for attracting pests to the pocket part of the lower container part.

[0008] The pest trap of the present invention is configured so that the upper lid is detachably fitted to a lower container portion having a pocket portion for capturing pests, thereby easily disposing of the pests captured in the pocket. The upper lid has a bottom portion connected to the inside periphery of the fitting portion and extending inward of the upper lid, and a lid portion connected to the bottom portion and provided so as to be openable and closable. Through-holes are provided between the lid portion and the bottom portion in the direction in which the lid portion extends, for luring pests into the pocket portion of the lower container portion. This allows pests to be attracted from the lid portion to the through-holes, and pests that enter the pocket portion through the through-holes to be reliably captured, without using adhesives or the like.

[0009] In addition, in the pest trap according to the present invention, the lid may be attached at a downward incline from the connection with the bottom, and the connection between the lid and the bottom may have an upwardly convex rib, so that when the lid is opened or closed vertically using the connection as a fulcrum, it returns to its original position. The downwardly inclined lid structure can guide and capture approaching insects. Furthermore, the provision of the rib can limit the lid's upward opening from its original position to some extent, thereby preventing captured insects from entering the pocket and opening the lid to escape.

[0010] In the pest trap according to the present invention, the rib portion may have a reinforcing portion on an upper surface thereof for improving the strength of the rib portion.

[0011] The pest trap according to the present invention may further include a step portion provided between the fitting receiving portion and the pocket portion, the step portion extending in a direction intersecting the extension direction of the pocket portion. By providing the step portion between the fitting receiving portion and the pocket portion, it is possible to increase the fitting strength when the fitting portion of the top cover is fitted into the fitting receiving portion.

[0012] The pest trap according to the present invention may also be characterized in that it has a plurality of trapping sections arranged in a line and connected to each other by connecting sections, each of which includes the lower container section and the upper lid that detachably fits to the lower container section, and the connecting sections are provided with a separation structure for separating the trapping sections. Since the plurality of trapping sections are arranged in a line and connected to each other by connecting sections, a pest trap having multiple trapping sections can be easily installed at one time. Furthermore, since the connecting sections are provided with a separation structure for separating the trapping sections, the trapping sections can be separated and used at any position.

[0013] In addition, in the pest trap according to the present invention, each of the lower container parts has an opening for fitting the upper lid into the fitting receiving part and a first flange part provided on the periphery of the opening, each of the upper lids has a second flange part provided on the periphery of the fitting part, and the connecting part of the trap part may include a lower connecting part connecting multiple lower container parts and an upper connecting part connecting multiple upper lids. Also, it may be characterized in that the lower connecting part is configured by connecting the first flange parts of adjacent lower container parts to each other, and the upper connecting part is configured by connecting the second flange parts of adjacent upper lids to each other. [Effects of the Invention]

[0014] The pest trap of the present invention is configured so that the upper lid is detachably fitted to a lower container portion having a pocket portion for capturing pests, thereby easily disposing of the pests captured in the pocket. The upper lid has a bottom portion connected to the inside periphery of the fitting portion and extending inward of the upper lid, and a lid portion connected to the bottom portion and provided so as to be openable and closable. Through-holes are provided between the lid portion and the bottom portion in the direction in which the lid portion extends, for luring pests into the pocket portion of the lower container portion. This allows pests to be attracted from the lid portion to the through-holes, and pests that enter the pocket portion through the through-holes to be reliably captured, without using adhesives or the like.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Pest traps according to several embodiments will be described below with reference to the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate descriptions will be omitted. In the description, terms indicating directions such as "upper" and "lower" are used for convenience based on the state shown in the drawings.

[0017] (First embodiment) First, a pest trap 1 according to a first embodiment will be described in detail. Fig. 1 is a schematic perspective view of the pest trap 1 according to the first embodiment. Fig. 2 is a schematic cross-sectional view of the pest trap 1 taken along line II-II in Fig. 1. As shown in Fig. 1, the pest trap 1 can have a lower container portion 2 and an upper lid 3 that is detachably fitted to the lower container portion 2.

[0018] 1 and 2, the lower container portion 2 can have a pocket portion 9 for capturing insects. The pocket portion 9 can have, for example, a convex shape that protrudes downward. A fitting-receiving portion 4 into which the top lid 3 fits is provided on the upper side of the pocket portion 9. The fitting-receiving portion 4 has an opening 6 into which the top lid 3 fits and a first flange-shaped portion 11 provided around the entire periphery of the opening 6. As shown in FIG. 2, when the pocket portion 9 is viewed in cross section, a step portion 7 extending in a direction intersecting the extension direction of the pocket portion 9 is provided between the fitting-receiving portion 4 and the pocket portion 9. The provision of this step portion 7 increases the fitting strength when the top lid 3 is fitted into the fitting-receiving portion 4. Therefore, when the top lid 3 is fitted into the lower container portion 2, the fitting-receiving portion 4 does not expand even if pressed, allowing the top lid 3 to be fitted into the lower container portion 2 and securely close the lid. In this embodiment, the fitting receiving portion 4 is formed around the entire periphery of the upper side of the lower container portion 2. The step portion 7 is provided so as to extend outward from the side wall 10 of the pocket portion 9. However, this is not limiting, and the step portion 7 may be provided so as to extend inward from the side wall 10 of the pocket portion 9.

[0019] Furthermore, the lower sidewalls 10 of the pocket 9 have a tapered shape, and are formed so that the distance between the opposing sidewalls gradually decreases as they go downward. The tapered shape of the sidewalls 10 of the pocket 9 makes it easier to insert the pest trap 1 into soil when using it, for example.

[0020] In this embodiment, an attractant substance may be placed inside the pocket 9 to make it easier to attract insects to the pocket 9. For example, the attractant substance may be atomized and sprayed inside the pocket, causing it to adhere to the inner wall surface of the pocket. In this case, an embossed structure with irregularities may be provided on all or part of the inner wall surface of the pocket to make it easier for the attractant substance to adhere to the inner wall surface.

[0021] When the pest trap 1 is used by hanging it, locking holes 32 for hanging it with a string or the like are formed on the periphery of the pest trap 1. In this embodiment, the locking holes 32 are formed as through holes at corresponding positions on the first flange portion 11 of the lower container portion 2 and the first flange portion 11 of the top lid 3.

[0022] In this embodiment, the pocket portion 9 and the fitting-receiving portion 4 may have a rectangular shape, but are not limited to this and may have a circular, elliptical, triangular, polygonal, etc. As explained above, the pocket portion 9 and the fitting-receiving portion 4 have almost similar cross-sectional shapes, but the fitting-receiving portion 4 has a larger shape than the pocket portion 9, and there is a step portion 7 between the pocket portion 9 and the fitting-receiving portion 4.

[0023] In this embodiment, the opening 6 of the fitting receiving portion 4 may have a rectangular shape measuring approximately 25 mm x 25 mm. The depth of the fitting receiving portion 4 may be approximately 2 mm. The width of the step portion 7 may be approximately 1 mm.

[0024] The depth of the pocket portion 9 can be approximately 20 mm. The size of the opening 6 of the fitting-receiving portion 4 or the depth of the pocket portion 9 can be changed as appropriate depending on the type and size of the pests to be captured.

[0025] 1 and 2, the top lid 3 may have a fitting portion 21 that fits into the fitting-receiving portion 4 of the lower container portion 2, a bottom portion 22 that is connected to the inside of the periphery of the fitting portion 21 and extends inside the top lid 3, and a lid portion 25 that is connected to the bottom portion 22 and is provided so as to be able to open and close. The fitting portion 21 may have a convex shape that protrudes downward. In addition, the top lid 3 may have a second flange portion 31 that is disposed opposite the first flange portion 11 of the lower container portion 2 when the top lid 3 is fitted into the fitting-receiving portion 4 of the lower container portion 2. In this embodiment, the second flange portion 31 is formed around the entire periphery outside the periphery of the fitting portion 21.

[0026] The bottom surface part 22 extends inward from the periphery of the fitting part 21 and has a structure that is inclined downward, so that insects and the like that come near are guided from the bottom surface part 22 of the upper lid 3 to the lid part 25 and are easily captured.

[0027] The lid portion 25 is an area for insects and the like to enter, and is attached integrally to a portion of the bottom portion 22 in an openable and closable manner. The lid portion 25 is formed, for example, so as to be able to open and close by folding up and down at the area connected to the bottom portion 22. The lid portion 25 is attached with a downward slope from the area connected to the bottom portion 22. Because it has a structure that slopes downward continuously from the bottom portion 22, it is designed to guide approaching insects and the like from the bottom portion 22 of the upper lid 3 to the lid portion 25 and to easily capture them in the pocket portion 9 via the lid portion 25. The lid portion 25 can be made of a material with a certain degree of elasticity, and can be formed so that the lid portion 25 returns to its original position when opened and closed up and down.

[0028] In the direction in which lid portion 25 extends, an opening is provided between lid portion 25 and bottom portion 22, forming through-hole 26. Insects and the like push down lid portion 25 and enter pocket portion 9 of lower container portion 2 through through-hole 26, where they are captured.

[0029] Referring to FIG. 2 , a rib portion 24 curved in an upward convex shape can be provided at the connection between the lid portion 25 and the bottom portion 22. The provision of the rib portion 24 can restrict the lid portion 25 from opening upward from its original position to some extent, thereby preventing insects that have entered the pocket portion 9 and been captured from opening the lid portion 25 and escaping. In addition, in this embodiment, a reinforcing portion 23 with increased thickness is provided in a portion of the rib portion 24, further restricting the lid portion 25 from opening upward from its original position. This ensures that insects and the like are captured in the pocket portion 9. Furthermore, the provision of the rib portion 24 can prevent defects such as a decrease in strength or breakage of the connection between the lid portion 25 and the bottom portion 22 even when the lid portion 25 is opened and closed multiple times due to insect intrusion. In this embodiment, the reinforcing portion 23 for reinforcing the rib portion 24 can be provided on the upper surface of the rib portion 24. In this embodiment, the reinforcing portion 23 is provided on both end sides of the rib portion 24 (see FIG. 6 ). However, the present invention is not limited to this, and the reinforcing portion 23 may be provided on a part or the entirety of the rib portion 24 .

[0030] In addition, a drain hole 8 is formed in the bottom of the pocket 9. In this embodiment, as shown in Fig. 2, the bottom of the pocket 9 has a structure that is inclined downward, and the drain hole 8 is formed at the tip of the structure. This allows liquids such as water that have accumulated in the pocket 9 to be efficiently discharged through the drain hole 8 when the pest trap 1 is used.

[0031] Furthermore, the pest trap 1 can be made of a plastic resin such as polystyrene. However, without being limited to this, a PET resin (polyethylene terephthalate resin) or the like can also be used. A biodegradable plastic resin can also be used. The pest trap 1 can also be made of a metal material such as iron or aluminum, or a paper material such as cardboard.

[0032] When the pest trap 1 is made of a plastic material, it can be formed by press molding using a mold, for example.

[0033] Next, the lower container portion 2 and the top cover 3 of the pest trap 1 will be described in detail. Figure 3 shows the top cover 3 and the lower container portion 2 of the pest trap 1 in a state before they are fitted together. Note that Figure 3(a) is a schematic perspective view of the top cover 3. Figure 3(b) is a schematic perspective view of the lower container portion 2 into which the top cover 3 fits. Figure 4 shows a top view of the lower container portion 2 of the pest trap 1. Figure 5 is a schematic cross-sectional view taken along line V-V in Figure 4. Figure 6 is a top view of the top cover 3 of the pest trap 1. Furthermore, Figure 7 is a schematic cross-sectional view taken along line VII-VII in Figure 6.

[0034] As shown in Figure 3, the pest trap 1 can be detachably fitted by inserting the fitting portion 21 of the top lid 3 into the opening 6 of the fitting-receiving portion 4 of the lower container portion 2. In this embodiment, the size of the fitting portion 21 of the top lid 3 is designed to be slightly larger than the size of the opening 6 of the fitting-receiving portion 4 of the lower container portion 2 with which it will fit. In this case, when the fitting portion 21 of the top lid 3 is inserted into the opening 6 of the fitting-receiving portion 4 of the lower container portion 2 and fitted, the fitting portion 21 of the top lid 3 deforms slightly inward and fits along the inner side surface of the fitting-receiving portion 4 of the lower container portion 2. Furthermore, the side surface of the fitting portion 21 of the top lid 3 has a tapered shape. When the fitting portion 21 of the upper lid 3 is inserted into the opening 6 of the fitting receiving portion 4 of the lower container part 2 and fitted, the side of the fitting portion 21 of the upper lid 3 always comes into contact with the side of the fitting receiving portion 4 of the lower container part 2, and the fitting portion 21 of the upper lid 3 is pressed against the fitting receiving portion 4 of the lower container part 2, deforming so that the side of the fitting portion 21 of the upper lid 3 comes into surface contact with the side of the fitting receiving portion 4 of the lower container part 2. As a result, the upper lid 3 can be fitted into the lower container part 2, ensuring reliable closure.

[0035] 4 and 5, a recess 5 can be provided at the corner of the fitting-receiving portion 4 of the lower container part 2. When fitting portion 21 of the top lid 3 is fitted into fitting-receiving portion 4, for example, if the corner of fitting portion 21 of the top lid 3 is slightly rounded due to processing errors or the like, the corner of fitting portion 21 of the top lid 3 may come into contact with fitting-receiving portion 4 of the lower container part 2, preventing proper fitting. Recess 5 prevents the corner of fitting portion 21 of the top lid 3 from coming into contact and preventing insertion into fitting-receiving portion 4 of the lower container part 2, and is formed by providing a so-called mouse-ear shaped gap in fitting-receiving portion 4 of the lower container part 2 at a location corresponding to the corner of fitting portion 21 of the top lid 3.

[0036] 6 and 7, as described above, the upper lid 3 may have a fitting portion 21 that fits into the fitting-receiving portion 4 of the lower container portion 2, a bottom portion 22 that is connected to the inner periphery of the fitting portion 21 and extends inward of the upper lid 3, and a lid portion 25 that is connected to the bottom portion 22 and is openable and closable. The bottom portion 22 extends inward from the periphery of the fitting portion 21 and has a downwardly inclined structure, making it easy to guide and capture approaching insects from the bottom portion 22 of the upper lid 3 to the lid portion 25. The lid portion 25 is openably and integrally attached to a portion of the bottom portion 22. In this embodiment, the fitting portion 21 has a rectangular shape corresponding to the shape of the fitting-receiving portion 4 of the lower container portion 2, and four bottom portions 22 extend inward from each side of the rectangle. The lid portion 25 is connected to one tip of the inwardly extending bottom portion 22 so as to be openable and closable vertically. A slit (cut) is provided between the bottom surface 22 adjacent to the bottom surface 22 to which the lid portion 25 is connected and the lid portion 25, thereby allowing the lid portion 25 to be opened and closed up and down. In addition, a through-hole 26 having a predetermined opening is provided between the bottom surface 22 arranged opposite the bottom surface 22 to which the lid portion 25 is connected and the lid portion 25, and insects and the like can be captured in the pocket portion 9 through this through-hole 26.

[0037] (Second embodiment) Next, a pest trap 101 according to a second embodiment will be described in detail. FIG. 8 is a schematic perspective view of the pest trap 101 according to the second embodiment. FIG. 8(a) is a schematic perspective view of the upper cover 103 of the pest trap 101 according to this embodiment, and FIG. 8(b) is a schematic perspective view of the lower container portion 102 into which the upper cover 103 of the pest trap 101 fits. FIG. 9 is a schematic perspective view of the pest trap 101 according to this embodiment. FIG. 9 shows the state in which the upper cover 103 of the pest trap 101 according to this embodiment is fitted into the lower container portion 102.

[0038] As shown in FIGS. 8 and 9, the pest trap 101 according to the second embodiment may have a structure in which a plurality of trapping sections 120 are connected and arranged linearly in a predetermined direction (the first direction shown in FIG. 9). The trapping section 120 has substantially the same structure as the pest trap 1 according to the first embodiment and may include a lower container section 102 and an upper lid 103 that detachably fits into the lower container section 102. The lower container section 102 may also have a pocket section 109 for trapping insects. The pocket section 109 may have, for example, a convex shape that protrudes downward. A fitting receiving section 104 into which the upper lid 103 fits is provided on the upper side of the pocket section 109. The fitting receiving section 104 has an opening 106 into which the upper lid 103 fits and a first flange-shaped section 111 provided around the entire periphery of the opening 106. Furthermore, when the pocket portion 109 is viewed in cross section, a step portion 107 is provided between the fitting receiving portion 104 and the pocket portion 109, extending in a direction intersecting the extension direction of the pocket portion 109. By providing this step portion 107, it is possible to prevent the fitting receiving portion 104 from expanding even if it is pressed when the upper cover 103 is fitted to the lower container portion 102. Therefore, the upper cover 103 can be fitted to the lower container portion 102 to securely close the lid. In this embodiment, similar to the pest trap 1 according to the first embodiment, the fitting receiving portion 104 is formed along the entire periphery of the upper side of the lower container portion 102. Furthermore, the step portion 107 is provided so as to extend outward from the side wall 110 of the pocket portion 109. However, this is not limited thereto, and the step portion 107 may be provided so as to extend inward from the side wall 110 of the pocket portion 109.

[0039] The upper lid 103 may have a fitting portion 121 that fits into the fitting-receiving portion 104 of the lower container portion 102, a bottom portion 122 that is connected to the inside of the periphery of the fitting portion 121 and extends inside the upper lid 103, and a lid portion 125 that is connected to the bottom portion 122 and is provided so as to be openable and closable. The fitting portion 121 may have a convex shape that protrudes downward. The upper lid 103 may also have a second flange portion 131 that is disposed opposite the first flange portion 111 of the lower container portion 102 when the upper lid 103 is fitted into the fitting-receiving portion 104 of the lower container portion 102. In this embodiment, as with the pest trap 1 according to the first embodiment, the second flange portion 131 is formed around the entire periphery outside the periphery of the fitting portion 121.

[0040] The bottom surface part 122 extends inward from the periphery of the fitting part 121 and has a structure that is inclined downward, so that insects and the like that come near are guided from the bottom surface part 122 of the upper lid 103 to the lid part 125 and are easily captured.

[0041] 8 and 9, connecting portions 160 are provided between the multiple capture portions 120 to connect the capture portions 120 to each other. Furthermore, the connecting portions 160 are provided with a plurality of lower container portions 102 that constitute the capture portions 120. Lower connecting portions 115 are provided to connect each of the lower container portions 102, and adjacent lower container portions 102 are connected to each other by the lower connecting portions 115. Similarly, the connecting portions 160 are provided with a plurality of upper lids 103 that constitute the capture portions 120. Upper connecting portions 135 are provided to connect each of the upper lids 103, and adjacent upper lids 103 are connected to each other by the upper connecting portions 135.

[0042] By fitting a plurality of lower container parts 102 and a corresponding plurality of upper lids 103 together, the lower connecting part 115 and the upper connecting part 135 are arranged opposite each other, and the connecting part 160 can be formed.

[0043] In this embodiment, the fitting receiving portion 104 of the lower container part 102 is provided with an opening 106 into which the top lid 103 is fitted, and a first flange portion 111 provided around the entire periphery of the opening 106. The top lid 103 can also have a second flange portion 131 that is positioned opposite the first flange portion 111 of the lower container part 102 when fitted into the fitting receiving portion 104 of the lower container part 102. In this embodiment, the second flange portion 131 is formed around the entire periphery, outside the periphery of the fitting portion 121. The first flange portions 111 of the lower container parts 102 are connected, and the first flange portions 111 of adjacent lower container parts 102 are connected to form a lower connecting portion 115. Similarly, the second flanges 131 of the top covers 103 are connected to each other, and the second flanges 131 of adjacent top covers 103 are connected to each other to form an upper connecting portion 135 .

[0044] Each trapping unit 120 may have substantially the same structure as the pest trap 1 according to the first embodiment. In the following description, detailed description of the configuration of each trapping unit 120 will be omitted unless necessary.

[0045] For simplicity, the present embodiment will describe a pest trap 101 having three trapping sections 120 (120a, 120b, 120c). The lower container section 102 may have three lower container sections 102 (102a, 102b, 102c). The upper cover 103 may also have three upper covers 103 (103a, 103b, 103c) corresponding to the lower container sections 102. The number of capture units 120 is not limited to three, but may be two or more, and any number of capture units 120 may be provided.

[0046] 8 and 9, this embodiment may have a first capture portion 120a, a second capture portion 120b, and a third capture portion 120c arranged in a first direction. Also, a first connection portion 160a may be disposed between the first capture portion 120a and the second capture portion 120b to connect the first capture portion 120a and the second capture portion 120b. Also, a second connection portion 160b may be disposed between the second capture portion 120b and the second capture portion 120c to connect the second capture portion 120b and the third capture portion 120c.

[0047] The first connecting portion 160a may include a first lower connecting portion 115 of the lower container portion 102 and a first upper connecting portion 135 of the upper cover 103. The first lower connecting portion 115 connects the first lower container portion 102a and the second lower container portion 102b to each other. The first upper connecting portion 135 connects the first upper cover 103a and the second upper cover 103b to each other.

[0048] Additionally, the second connecting portion 160b may include a second lower connecting portion 115 of the lower container portion 102 and a second upper connecting portion 135 of the upper cover 103. The second lower connecting portion 115 connects the second lower container portion 102b and the third lower container portion 102c to each other. Additionally, the second upper connecting portion 135 connects the second upper cover 103b and the third upper cover 103c to each other.

[0049] In this embodiment, the opening 106 of the lower container portion 102 can have a rectangular shape of approximately 25 mm x 25 mm, similar to the pest trap 1 according to the first embodiment. The depth of the pocket portion 109 can be approximately 20 mm. The length l1 in the first direction of the lower connecting portion 115 can be approximately 30 mm. The size of the opening 106 of the lower container portion 102 or the depth of the pocket portion 109 can be changed as appropriate depending on the type and size of the pests to be trapped, etc.

[0050] Furthermore, the first capturing part 120a, the second capturing part 120b, and the third capturing part 120c may have substantially the same structure.

[0051] The side walls 110 of the downwardly convex pocket 109 may have a tapered shape, with the distance between opposing side walls gradually decreasing downward. The tapered side walls 110 of the pocket 109 make it easier to insert the pest trap 101 into soil when using it. The opening 106 may have a rectangular shape, but is not limited to this and may have a circular, elliptical, triangular, polygonal, or other shape.

[0052] As explained above, the upper lid 103 may have a plurality of fitting portions 121 for detachably fitting with the lower container portion 102 to form a lid. Each of the fitting portions 121 may have a convex shape that protrudes downward. The fitting portion 121 may have a fitting portion 121 for fitting with the lower container portion 102, and a bottom surface portion 122 connected to the fitting portion 121. A lid portion 125 is formed on the bottom surface portion 122. The lid portion 125 may have a through-hole 126 for allowing insects and the like to enter.

[0053] Additionally, upper connecting portions 135 for connecting the fitting portions 121 to each other are provided between the plurality of fitting portions 121, and the upper connecting portions 135 connect the adjacent fitting portions 121 to each other.

[0054] In this embodiment, a description will be given of an upper cover 103 provided with three fitting portions 121 (121a, 121b, 121c) corresponding to the capture portions 120. Note that the number of fitting portions 121 is not limited to three, and any number of fitting portions 121 may be provided as long as it is two or more corresponding to the number of capture portions 120.

[0055] 8 and 9, the container may have a first fitting portion 121a, a second fitting portion 121b, and a third fitting portion 121c arranged in order in the first direction corresponding to the first fitting receiving portion 104a, the second fitting receiving portion 104b, and the third fitting receiving portion 104c of the lower container portion 102. The container may also have a first upper connecting portion 135a disposed between the first fitting portion 121a and the second fitting portion 121b for connecting the first fitting portion 121a and the second fitting portion 121b. The container may also have a second upper connecting portion 135b disposed between the second fitting portion 121b and the third fitting portion 121c for connecting the second fitting portion 121b and the third fitting portion 121c.

[0056] In this embodiment, the fitting portion 121 can have a sidewall that protrudes downward. This sidewall has a tapered shape, and is formed so that the distance between opposing sidewalls gradually decreases as it goes downward. When the upper lid 103 is fitted to the lower container portion 102 to close the lid, the sidewall of the fitting portion 121 comes into surface contact with the sidewall of the fitting receiving portion 104 of the lower container portion 102, thereby closing the lid.

[0057] The size of the fitting portion 121 corresponds to the size of the opening 106 of the lower container portion 102, and can have a rectangular shape of approximately 25 mm x 25 mm. Note that, in order to reliably fit the upper lid 103 into the lower container portion 102, the size of the fitting portion 121 can be slightly larger than the size of the opening 106 of the lower container portion 102. In this embodiment, the size of one side of the fitting portion 121 is approximately 0.3 mm larger than the size of the opening 106 of the lower container portion 102. The depth of the fitting portion 121 can be approximately 4 mm. The length l2 in the first direction of the upper connecting portion 135 corresponds to the length of the lower connecting portion 115, and can be approximately 30 mm. Note that the size of the fitting portion 121 or the size of the through-hole 126 can be changed as appropriate depending on the type and size of the pests to be captured.

[0058] Furthermore, the shape of the fitting portion 121 of the upper lid 103 can be rectangular, circular, elliptical, triangular, polygonal, or other shape to match the shape of the capture portion of the lower container portion 102 .

[0059] 8 and 9, a first flange portion 111 is provided around the entire periphery of each of the openings 106 of the fitting receiving portions 104 of the lower container parts 102 (lower container part 102a, lower container part 102b, and lower container part 102c) included in each of the multiple capture parts 120 (first capture part 120a, second capture part 120b, and third capture part 120c in this embodiment). The multiple lower container parts 102 are connected by the first flange portions 111 formed between each of the lower container parts 102. Furthermore, the first flange portions 111 provided on the side edges of the openings 106 of each fitting receiving portion 104 are continuously connected in the first direction across the multiple lower container parts 102. This increases the connection strength of the multiple lower container parts 102 that are connected to each other. Furthermore, first flange portion 111 provided on the side of opening 106 of fitting-receiving portion 104 can have a plurality of first side edge through-holes 170 formed in a line in the first direction. Providing these first side edge through-holes 170 can improve the flexibility (bendability) of the connection portion of multiple lower container portions 102. This allows multiple linearly connected lower container portions 102 to be easily wound around a reel, making them easy to transport or store.

[0060] Similarly, a second flange portion 131 is provided on the entire periphery of each of the fitting portions 121 of the top covers 103 (top covers 103a, 103b, and 103c) included in each of the multiple capture portions 120 (in this embodiment, first capture portion 120a, second capture portion 120b, and third capture portion 120c). The multiple top covers 103 are connected by the second flange portions 131 formed between each of the fitting portions 121. Furthermore, the second flange portions 131 provided on the side edges of each of the fitting portions 121 are continuously connected in the first direction across the multiple top covers 103. This increases the connection strength of the multiple top covers 103 that are connected to each other. Furthermore, the second flange portions 131 provided on the side edges of the fitting portions 121 can have multiple second side edge through holes 171 formed side by side in the first direction. Providing this second side edge through-hole 171 can improve the flexibility (bendability) of the connection portion of the multiple top covers 103. This allows the multiple top covers 103 connected in a straight line to be easily wound around a reel, making them easy to transport or store.

[0061] Next, a modified example of the pest trap 101 of this embodiment will be described in detail. Fig. 10 is a schematic perspective view of the pest trap 201 according to this embodiment. Fig. 10(a) is a schematic perspective view of the upper cover 103 of the pest trap 201 according to this embodiment. Fig. 10(b) is a schematic perspective view of the lower container part 102 into which the upper cover 103 is fitted in the pest trap 201 according to this embodiment. Fig. 11 is a schematic view of the pest trap 201 shown in Fig. 10 with the upper cover 103 fitted into the lower container part 102.

[0062] 10 and 11, in the lower container portion 102, a lower separation structure 140 extending in a direction intersecting the first direction is provided between each of the plurality of fitting receiving portions 104 arranged in the first direction. Similarly, in the upper lid 103 that fits into the lower container portion 102, an upper separation structure 150 extending in a direction intersecting the first direction is provided between each of the plurality of fitting portions 121 arranged in the first direction, corresponding to the lower separation structure 140. Note that in this embodiment, the structure is the same as that of the pest trap 101, except that the lower container portion 102 is provided with the lower separation structure 140 and the upper lid 103 is provided with the upper separation structure 150, and therefore, explanation will be omitted unless particularly necessary.

[0063] In this embodiment, the separation structure may have a concave groove structure, but is not limited thereto, and may be a hole structure, a perforated structure, or the like.

[0064] In this embodiment, lower separation structures 140a and 140b can be provided between the first pocket portion 109a, the second pocket portion 109b, and the third pocket portion 109c in the lower container portion 102. The lower separation structures 140 (140a, 140b) can be recessed groove structures. By providing the lower separation structure 140, the separation points can be easily visualized, facilitating the separation of the pocket portions 109. Furthermore, since the lower separation structure 140 is easily bendable, the lower container portion 102 can be wound around a reel or the like for transportation, making it easy to handle. Furthermore, lower separation structure reinforcement portions 141 are provided at both ends in the direction in which the lower separation structure 140 extends. Providing the lower separation structure reinforcement portions 141 can prevent the lower container portion 102 from twisting or deforming. Furthermore, the strength of the area where the lower separation structure 140 is provided is increased, thereby avoiding problems such as breakage.

[0065] Similarly, upper separation structures 150a and 150b can be provided in the upper cover 103 between the first fitting portion 121a, the second fitting portion 121b, and the third fitting portion 121c, respectively. The upper separation structures 150 (150a, 150b) can be recessed groove structures. By providing the upper separation structure 150, the separation location can be easily visually recognized, making it easier to separate the fitting portions 121 from each other. Furthermore, since the upper separation structure 150 is easily bendable, the upper cover 103 can be wound around a reel or the like for transportation, making it easier to handle. Furthermore, upper separation structure reinforcement portions 151 are provided at both ends in the extension direction of the upper separation structure 150. Providing the upper separation structure reinforcement portions 151 can prevent the upper cover 103 from twisting or deforming. Furthermore, the strength of the area where the upper separation structure 150 is provided is increased, making it possible to avoid defects such as breakage.

[0066] In this way, by providing the lower container part 102 and the upper lid 103 with the lower separation structure 140 and the upper separation structure 150, respectively, the parts can be cut and separated at the areas where these separation structures are provided. This allows for the construction of a pest trap 201 having any length and any number of trapping parts 120 depending on the place of use or the purpose of use.

[0067] The pest trap 101 includes a lower container portion 102 and an upper lid 103 that detachably fits onto the lower container portion 102, and is configured to have a plurality of trapping portions 120 that are linearly arranged at predetermined intervals in a first direction. This allows a plurality of trapping portions 120 to be easily installed at once, simplifying the installation process. Furthermore, when retrieving the pest trap 101, the plurality of trapping portions 120 can be retrieved at once. Furthermore, by arranging the plurality of trapping portions 120 at predetermined intervals, even if a trapping portion 120 fails to capture an insect, it will be captured by the adjacent trapping portions 120, making it possible to efficiently and reliably capture insects and the like.

[0068] (Comparative Example) Fig. 12 shows a prototype pest trap 301 for comparison. Fig. 12(a) is a schematic perspective view of the pest trap 301. Fig. 12(b) is a cross-sectional view taken along line XII-XII in Fig. 12(a).

[0069] 12, a pest trap 301 may have a lower container portion 202 and an upper lid 203 that detachably fits into the lower container portion 202. The lower container portion 202 may have a pocket portion 209 for trapping insects. The pocket portion 209 may have, for example, a convex shape that protrudes downward. The pocket portion 209 may also have a first flange portion 211 provided around the entire periphery of the opening 206. The side surface of the pocket portion 209 extends from the bottom surface portion to the opening 206, and the fitting receiving portion 4 of the pest trap 1 of the first embodiment is not formed therein.

[0070] The top lid 203 has a fitting portion 221 that fits into the opening 206 of the lower container portion 202, and a bottom portion 222 that is connected to the inside of the periphery of the fitting portion 221 and extends inside the top lid 203. The top lid 203 does not have the lid portion 25 that is connected to the bottom portion 22 of the pest trap 1 of the first embodiment and is provided so as to be openable and closable. The top lid 203 may also have a second flange portion 231 that is disposed opposite the first flange portion 211 of the lower container portion 202 when the top lid 203 is fitted to the lower container portion 202. In this embodiment, the second flange portion 231 is formed around the entire periphery outside the periphery of the fitting portion 221. The bottom portion 222 has an opening and a through-hole 226 that allows insects and the like to enter through the opening and be captured in the pocket portion 209.

[0071] A pest trap experiment was conducted using the pest trap 301 and the pest trap 1 of the first embodiment. In the pest trap 301, insects and the like could be guided into the pocket portion 209 via the through-hole 226 of the top cover 203 and trapped there. However, since the pest trap 301 does not have the cover portion 25 provided on the bottom portion 22 of the pest trap 1 of the first embodiment, insects once trapped in the pocket portion 209 may escape to the outside through the through-hole 226, and therefore the trapping rate was lower than that of the pest trap 1.

[0072] Furthermore, unlike the pest trap 1 of the first embodiment, there is no fitting receiving portion 4 on the upper side of the pocket portion 9 for the top cover 3 to fit into, so the top cover 203 is easily removed, and even if an insect captured in the pocket portion 209 moves, the top cover 203 may come off and the insect may escape.

[0073] On the other hand, when the pest trap 1 of the first embodiment is used, the lid portion 25 opens downward when an insect approaches the upper side of the top lid 3, guiding the insect into the pocket portion 9 where it can be trapped. After trapping the insect, the rib structure of the lid portion 25 causes the lid portion 25 to return to its original position, so that once the insect is trapped, it cannot escape to the outside, ensuring reliable capture of the insect. In addition, by fitting the fitting portion 21 of the top lid 3 into the fitting receiving portion 4 of the pocket portion 9, the top lid 3 can securely cover the lower container portion 2, and the structure makes it difficult for the lid to come off, preventing the insect from escaping.

[0074] Next, a method of using the pest traps (1, 101, 201) of this embodiment will be described in detail. In the following description, for simplicity, an example of using the pest trap 1 will be described, but the pest traps 101 and 201 can be used in the same way. It goes without saying that the pest trap 301 described in the comparative example can also be used in the same way.

[0075] Figure 13 is a diagram illustrating an example of how to use the pest trap 1. Figure 13 shows the case where the pest trap 1 is used by hanging it in, for example, a cowshed. The pest trap 1 has a locking hole 32 formed on its periphery for hanging it with a string or the like.

[0076] In this embodiment, an attractant substance for attracting insects can be placed and used inside the pocket 9. In Fig. 13, an attractant substance for attracting insects can be sprayed into the pocket 9 with a spray or the like and attached to the inner wall surface of the pocket 9. For example, a pheromone substance specific to a pest can be used as the attractant substance.

[0077] In this embodiment, in order to make it easier for the attractant to adhere to the inner wall surface, an embossed structure with irregularities can be provided on the entire or part of the inner wall surface of the pocket portion 9 (not shown). This allows the attractant to easily adhere to the inner wall surface when sprayed in the form of a mist into the pocket portion 9.

[0078] Also, Fig. 14 shows another example of how to use the pest trap 1. For ease of understanding, Fig. 15 shows a schematic cross-sectional view taken along line XV-XV in Fig. 14. Figs. 14 and 15 show a case where the pest trap 1 is used by being buried in soil around, for example, planted crops. In this embodiment, the side wall 10 of the pocket portion 9 has a tapered shape, which makes it easier to insert the pest trap 1 into soil when using it, for example.

[0079] After using the pest trap 1 to capture pests, the trap can be reused by opening the top lid 3 and removing the captured pests. Alternatively, the trap may be disposed of with the insects still attached, with the top lid 3 still on. In this case, by constructing the pest trap 1 from a material containing biodegradable plastic, the trap can be made to decompose naturally in the soil, thereby reducing the problem of plastic waste.

[0080] In the second embodiment, a structure in which multiple capture sections 120 are connected and arranged in a linear fashion in a predetermined direction (first direction) has been described, but this is not limited to this, and the capture sections 120 can also be arranged two-dimensionally on a plane and connected to each other.

[0081] While the principles of the present invention have been illustrated and described in preferred embodiments, it will be recognized by those skilled in the art that the present invention can be modified in arrangement and detail without departing from such principles. The present invention is not limited to the particular constructions disclosed herein. We therefore claim all modifications and variations that come within the scope and spirit of the following claims. [Explanation of symbols]
