By simplifying the structure of the insect trap, the user's assembly time is reduced, making assembly easier. [Solution] The insect trap 1 comprises a container body 10, a lid 20 having an insect introduction hole 20a and being placed on top of the container body 10 in a non-fitted state, and a roof 30 having a protruding plate portion 33a that fits a portion of the outer circumference in the circumferential direction to the container body 10 and restricts the upward displacement of the lid 20.

Description

Technical Field

[0001] The present disclosure relates to a pest trap that captures pests such as wasps, for example.

Background Art

[0002] For example, as a wasp trap, there is known a device in which a trapping liquid for attracting wasps is stored inside a cup-shaped container, and a lid having an introduction hole for introducing wasps is attached to the upper part of the container (see, for example, Patent Document 1). The wasp trap of Patent Document 1 includes a container body, a lid having an introduction hole, and a collision plate for colliding with flying wasps.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the wasp trap of Patent Document 1 has a structure in which the lid and the collision plate are fitted after the container body and the lid are fitted, and there is a problem that the number of assembly steps of the wasp trap increases because two fitting locations are required.

[0005] The present disclosure has been made in view of such a point, and an object thereof is to simplify the structure of the pest trap, thereby reducing the number of assembly steps for the user and simplifying the assembly.

Means for Solving the Problems

[0007] With this configuration, when assembling the lid to the container body, the lid is placed on top of the container body, and the fitting portion of the roof is fitted to the container body, thereby suppressing upward displacement of the lid. As a result, a structure for fitting the lid to the container body becomes unnecessary, simplifying the structure and reducing assembly time by eliminating the process of fitting the lid to the container body.

[0008] A flange portion extending radially outward and circumferentially may be formed on the upper part of the container body. In this case, a mounting portion can be formed on the outer circumference of the lid to rest on the flange portion. This allows the lid to be stabilized when placed on the upper part of the container body.

[0009] The upper part of the container body may have a container-side extension that extends downward from the radial outer edge of the flange portion. In this case, the outer circumference of the lid can have a lid-side extension that extends downward from the radial outer edge of the mounting portion along the container-side extension. This makes it more difficult for the lid to move radially relative to the container body when it is placed on top of the container body, thus further stabilizing the lid.

[0010] The fitting portion of the roof can be formed to surround the upper surface of the mounting portion of the lid, the side surface of the lid-side extension, and the lower end surface of the container-side extension. This ensures that upward displacement of the lid is reliably restricted when the fitting portion is fitted to the container body, and the lid can be kept in a predetermined position.

[0011] The lower part of the container-side extension may have a lower extension that extends radially inward. In this case, the lower surface of the lower extension can constitute the lower end surface of the container-side extension.

[0012] Multiple locations on the outer perimeter of the roof may be formed to extend downward and may also have the fitting portions. This allows multiple locations of the roof to be fitted onto the container body.

[0013] A suspension section can be provided in the center of the roof, and by tying a thread or string to this suspension section, the insect trap can be used while suspended. In this case, since the outer perimeter of the roof is fitted to the container body, the container body containing the attractant liquid can be prevented from falling. [Effects of the Invention]

[0014] As explained above, by fitting the roof's fitting portion to the container body, upward displacement of the lid can be suppressed, thus simplifying the assembly of the insect trap. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described in detail based on 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.

[0017] FIG. 1 shows a bug catcher 1 according to an embodiment of the present invention. The bug catcher 1 can capture, for example, flying pests and the like. The bugs captured by the bug catcher 1 are not limited to pests, and may be bugs that do not harm humans, crops, etc. Examples of the bugs captured by the bug catcher 1 include, for example, wasps, hornets, yellow jackets, moths, flies, and click beetles. When the bug catcher 1 captures, for example, bees, the bug catcher 1 can be called a bee catcher, and particularly when capturing wasps, it can be called a wasp catcher.

[0018] The bees captured by the insect trap 1 include, for example, the Japanese honeybee, the yellow-legged hornet, the small Japanese hornet, the paper wasp, the dwarf hornet, the black-and-yellow mud dauber, the red paper wasp, etc. The hornets captured by the insect trap 1 include, for example, the yellow hornet, the Asian giant hornet, etc. The wasps captured by the insect trap 1 include, for example, the common wasp, the Japanese yellow hornet, the emperor wasp, the bald-faced hornet, the great black wasp, etc. The flies captured by the insect trap 1 include, for example, the housefly, the blowfly, the flesh fly, etc. The beetles captured by the insect trap 1 include, for example, the green tiger beetle, the common click beetle, the false click beetle, the spotted click beetle, the long-horned click beetle, the large click beetle, the four-spotted click beetle, the small click beetle, the metallic wood-boring beetle, the bean weevil, etc. Thus, flying beetles can also be targeted for capture.

[0019] As also shown in FIGS. 2 to 7, the insect trap 1 includes a container body 10 for housing the insects captured therein, a lid 20, and a roof 30. The insect trap 1 is a device for introducing, capturing, and exterminating insects into the container body 10, and is configured to be used, for example, by hanging it on a tree or a pole, or placing it on a stand.

[0020] In this description of the embodiment, as shown in Figure 1, we define the left and right sides of the insect trap 1, as well as the front and back sides. However, this is solely for the convenience of explanation and does not limit the actual orientation during use, manufacturing, assembly, packaging, or storage. Either side of the insect trap 1 may be the right or the left. Furthermore, the front side of the insect trap 1 may be called the front side, and the back side may be called the rear side.

[0021] (Composition of the container body 10 and the attractant liquid) As shown in Figure 5, the container body 10 is cup-shaped with an open top and has a cylindrical peripheral wall. Inside the container body 10 is an attractant liquid for attracting insects. The attractant liquid may or may not be a component of the insect trap 1. The attractant liquid is a liquid agent that has the effect of attracting insects. For example, if the target of capture is wasps, it is a liquid agent for attracting and capturing wasps. In this case, the attractant liquid may also be called wasp attractant liquid, wasp trapping liquid, etc. In particular, the attractant liquid of this embodiment artificially reproduces the fermented odor of tree sap that attracts insects such as wasps in nature, and can be called artificial tree sap. The attractant liquid contains sugar, yeast, alcohol, and water as components of the artificial tree sap. Furthermore, the attractant liquid of this embodiment contains a food additive surfactant (nonionic surfactant) as an escape prevention component. Note that the attractant liquid is not limited to the above. Furthermore, the attractant liquid can be prepared according to the target insect. Alternatively, a solid attractant may be placed in the container body 10.

[0022] Sugars can be, for example, high-fructose corn syrup. The content of high-fructose corn syrup can be, for example, between 1 w / v% and 75 w / v%. Yeast can be, for example, dry yeast. The content of yeast can be, for example, between 0.001% by mass and 5% by mass. By adding yeast, the sugar is fermented by the yeast to produce alcohol and carbon dioxide.

[0023] The alcohol can be at least one of the following: ethanol, butane-2,3-diol, and glycerin. Any mixture of these can also be used. The alcohol content can be, for example, between 0.01 w / v% and 15 w / v%. Although alcohol is produced by yeast fermentation and can therefore be omitted, adding alcohol allows for good attraction even in the early stages of fermentation.

[0024] The attractant liquid may contain acetic acid. The acetic acid content can be, for example, between 0.005 w / v% and 0.5 w / v%. The attractant liquid may also contain lactic acid. The lactic acid content can be, for example, between 0.005 w / v% and 5 w / v%. Since acetic acid and lactic acid form esters with alcohols, the composition may change during long-term storage if they are combined simultaneously. Therefore, from the viewpoint of long-term storage, it is preferable to omit at least one of acetic acid, lactic acid, or alcohol.

[0025] Furthermore, the attractant liquid may contain sodium propionate. The sodium propionate content can be, for example, 0.005 w / v% to 0.5 w / v%.

[0026] When a surfactant is added to artificial sap as an ingredient to prevent captured insects from escaping, a nonionic surfactant is preferred because it does not adversely affect yeast, and food-grade surfactants are particularly preferred, as in this embodiment. At least one of polyoxyethylene sorbitan monolaurate and polyoxyethylene sorbitan monooleate can be used as the food-grade surfactant, and any combination of several of these can also be used. The content of the food-grade surfactant can be, for example, 0.001 w / v% to 1.0 w / v%. Since the surfactant is a food-grade surfactant, it is less likely to adversely affect yeast fermentation, allowing for a rapid start of yeast fermentation at the beginning of use, and providing a high attractant effect over a long period of time. As a food-grade surfactant, for example, Tween20, Tween80, etc. manufactured by Tokyo Chemical Industry Co., Ltd. can be used.

[0027] The attractant liquid contains dry yeast as a component of the yeast. This causes the attractant liquid to ferment due to the action of the yeast. The odor produced by fermentation can enhance the attraction effect on insects such as bees. Examples of dry yeast include Kyoritsu Foods' 3g pack of value-size dry yeast (Kyoritsu Dry Yeast) and Nissin Foods' Nissin Super Camellia vacuum pouch 3g (Nissin Dry Yeast).

[0028] The container body 10 is made of, for example, an elastically deformable resin material. Examples of this resin material include polyethylene terephthalate, polypropylene, polyethylene, polystyrene, and polycarbonate. The container body 10 may also be made of a material other than resin, or it may be made of a laminate material of resin and paper.

[0029] The thickness of the container body 10 is preferably 0.1 mm to 5.0 mm, and more preferably 0.5 mm to 3.0 mm. The container body 10 can be obtained by heat-press molding of a resin sheet, but it may also be obtained by injection molding of a resin material. The visible light transmittance of the resin material constituting the container body 10 can be the percentage of light with wavelengths of approximately 400 nm to approximately 700 nm that is transmitted, and can be set to, for example, 30% or more.

[0030] The outer diameter of the container body 10 is not particularly limited, but can be set to, for example, 150 mm or less, or 130 mm or less. The height of the container body 10 is not particularly limited, but can be set to, for example, 200 mm or less, or 180 mm or less. The inner diameter of the container body 10 may increase towards the top, or it may be the same diameter from top to bottom.

[0031] In this embodiment, the container body 10 has an outer diameter at its lower end that is smaller than the outer diameter at its upper end, and the outer diameter decreases as you approach the lower end. Although not shown in the figures, the outer diameter at the lower end of the container body 10 may be larger than the outer diameter at its upper end, in which case the outer diameter decreases as you approach the upper end.

[0032] The upper part of the container body 10 has a flange portion 11 that extends radially outward and circumferentially, and a container-side extension portion 12 that extends downward from the radial outer edge of the flange portion 11. The flange portion 11 and the container-side extension portion 12 are integrally molded. The flange portion 11 is formed around the entire circumference of the container body 10 so as to surround the upper end opening of the container body 10, and forms an annular shape in plan view. The container-side extension portion 12 is also formed around the entire circumference of the container body 10 and forms an annular shape. The lower part of the container-side extension portion 12 has a lower extension portion 12a that extends radially outward, and the lower surface of this lower extension portion 12a constitutes the lower end surface of the container-side extension portion 12. The lower extension portion 12a may also extend radially inward. The lower extension 12a is formed around the entire circumference of the container body 10 and forms an annular shape in plan view.

[0033] (Composition of lid 20) The lid 20 closes the upper opening of the container body 10, and an introduction hole 20a is formed in its center for introducing insects into the container body 10. The shape of the introduction hole 20a can be, for example, circular, but is not limited to this, and may be, for example, elliptical or polygonal. In this embodiment, there is one introduction hole 20a, but there may be two or more. If two or more introduction holes 20a are provided, they can be spaced apart from each other and can be formed in parts other than the center of the container body 10.

[0034] The diameter of the entry hole 20a can be set to 20 mm or more and 35 mm or less. If the diameter of the entry hole 20a is less than 20 mm, it becomes difficult for large wasps such as giant hornets to enter the entry hole 20a, and the capture rate of large wasps decreases. On the other hand, if the diameter of the entry hole 20a is larger than 35 mm, there is a higher possibility that butterflies, moths, and beetles other than wasps will enter, so when targeting large wasps, a diameter of 35 mm or less is preferable for the entry hole 20a. Therefore, by setting the diameter of the entry hole 20a to 20 mm or more and 35 mm or less, the capture rate of large wasps can be increased. It is even more preferable to set the diameter of the entry hole 20a to 30 mm or less. When targeting small insects, the diameter of the entry hole 20a can be smaller than 35 mm, and the diameter of the entry hole 20a can be set according to the insect to be captured.

[0035] A cylindrical portion 20b is formed on the periphery of the introduction hole 20a, projecting downward and extending continuously in the circumferential direction. The vertical dimension of the cylindrical portion 20b is preferably 1 mm or more and 20 mm or less.

[0036] The lower end of the cylindrical portion 20b and the surface of the attractant liquid are separated by a predetermined distance or more. This predetermined distance is set such that, for example, when a giant hornet is captured and floating on the surface of the attractant liquid, it is difficult for the hornet's hands and legs to reach the periphery of the cylindrical portion 20b, and is, for example, 30 mm or more. The above predetermined distance can also be set to 40 mm or more.

[0037] The lid 20 can be made of the same material as the container body 10. The thickness of the lid 20 can also be approximately the same as the thickness of the container body 10. The visible light transmittance of the resin material constituting the lid 20 can be set to the percentage of light with wavelengths of approximately 400 nm to approximately 700 nm that is transmitted, and can be set to, for example, 20% or more, with 10% or less being more preferable.

[0038] The resin material that makes up the lid 20 is colored, for example, black. It may also be colored in any other color, such as brown, blue, navy blue, or green. The diameter of the lid 20 should be set to correspond to the outer diameter of the top of the container body 10, and can be set to, for example, within 150 mm.

[0039] The lid 20 is a component that is not fitted to the container body 10 and is placed on top of the container body 10. The non-fitted state means that the lid 20 is not fitted, engaged, or locked to the container body 10, and the container body 10 is not fitted, engaged, or locked to the lid 20, and the lid 20 is simply placed on top of the container body 10. Because the lid 20 is in a non-fitted state, if the container body 10 is inverted while the lid 20 is placed on top of it, the lid 20 may fall off due to its own weight.

[0040] The outer circumference of the lid 20 is formed with a mounting portion 21 that rests on the flange portion 11 of the container body 10, and a lid-side extension portion 22 that extends downward from the radial outer edge of the mounting portion 21 along the container-side extension portion 12. The mounting portion 21, like the flange portion 11, is annular in shape when viewed from above. Therefore, when the lid 20 is placed on the flange portion 11 of the container body 10, the annular portion of the container body 10 and the annular portion of the mounting portion 21 come into contact with each other, and the lid 20 remains stable even when not fitted.

[0041] The lid extension 22 is formed around the entire circumference of the lid 20 and, for example, forms an annular shape. The lid extension 22 is positioned outside the container extension 12 of the container body 10. The inner circumferential surface of the lid extension 22 is in contact with the outer circumferential surface of the container extension 12. The lid extension 22 may be provided continuously or intermittently in the circumferential direction.

[0042] An inner inclined surface 23 is formed around the inlet hole 20a in the lid 20, which is inclined so that it is positioned higher towards the radially outward direction. The inner inclined surface 23 is continuous in the circumferential direction and is a surface for guiding insects into the inlet hole 20a. The inclination angle of the inner inclined surface 23 with respect to the vertical is preferably 30 degrees or more, and more preferably 45 degrees or more. Setting the inner inclined surface 23 at this angle makes it easier for insects, such as bees, to enter the inlet hole 20a.

[0043] As shown in Figure 7, an outer inclined surface 24 is formed around the inner inclined surface 23 of the lid 20, which is inclined so that it is lower as it moves radially outward. The outer inclined surface 24 is continuous in the circumferential direction, and the outer circumference of the outer inclined surface 24 is continuous with the mounting portion 21. The outer inclined surface 24 is a surface that prevents rain, for example, from entering the introduction hole 20a when the insect trap 1 is installed outdoors. The inclination angle of the outer inclined surface 24 with respect to the horizontal is preferably 1 degree or more, and more preferably 5 degrees or more. By setting the inclination angle of the outer inclined surface 24 to this angle, raindrops are less likely to enter the introduction hole 20a even when it is raining from the side, without negatively affecting the attractiveness of bees.

[0044] The inner inclined surface 23 is inclined so that it is higher as it extends radially outward, and the outer inclined surface 24 is inclined so that it is lower as it extends radially outward. As a result, the lid 20 has a shape in which the boundary between the inner inclined surface 23 and the outer inclined surface 24 is the highest point, and from that boundary, it slopes downward in both radially outward and inward directions. The ratio (W1 / W2) of the width W2 of the inner inclined surface 23 to the width W1 (shown in Figure 7) of the outer inclined surface 24 is preferably 1 / 9 to 9 / 1, and more preferably 2 / 3 to 2 / 1. By setting W1 / W2 within this range, it becomes more difficult for raindrops to enter the inlet hole 20a, and in particular, the attractiveness to bees can be enhanced.

[0045] As shown in Figures 1 and 5, the outer inclined surface 24 has multiple protrusions 24a formed on it at intervals from each other in the circumferential direction. The protrusions 24a have a radially elongated shape, making them slender protrusions.

[0046] (Roof 30 composition) The roof 30 is a component positioned to cover the introduction hole 20a formed in the lid 20 from above, and is a component that prevents, for example, raindrops from entering the inside of the container body 10 through the introduction hole 20a when the insect trap 1 is installed outdoors. The roof 30 is made of, for example, a resin material. Examples of this resin material include polyethylene terephthalate, polypropylene, polyethylene, polystyrene, and polycarbonate. The thickness of the roof 30 is preferably 0.3 mm to 5.0 mm. The visible light transmittance of the resin material constituting the roof 30 can be the percentage of light with wavelengths of approximately 400 nm to approximately 700 nm that is transmitted, and can be set to, for example, 20% or less, with 10% or less being more preferable. The resin material constituting the roof 30 is colored black, for example. In addition to black, it may be colored brown, blue, navy blue, or green.

[0047] The roof 30 has a curved section 31 that is curved such that the center is the highest point and the curved section becomes lower as it approaches the outer edge. This curved section 31 may be hemispherical (dome-shaped), conical, or polygonal pyramidal. If the shape of the curved section 31 is conical or polygonal pyramidal, an inclined surface will be formed on the outer surface of the curved section 31.

[0048] A suspension section 32 is provided in the center of the roof 30 so as to protrude upward. A through hole 32a is formed in the suspension section 32. The through hole 32a allows a string, thread, wire, etc. to be passed through, and the insect trap 1 can be used by suspending it from a tree branch or pole using the string, thread, wire, etc. Note that the suspension section 32 may be provided as needed and may be omitted.

[0049] A portion of the outer periphery of the roof 30 is a column portion 33 formed to extend downward. In this embodiment, four portions of the outer periphery of the roof 30 are each a column portion 33, and therefore the four curved portions 31 are supported by the column portions 33. The column portions 33 are provided at equal intervals (90-degree intervals) in the circumferential direction. The number of column portions 33 is not limited to four; there may be three or fewer, or five or more. Also, the spacing of the column portions 33 in the circumferential direction may be unequal. Furthermore, the column portions 33 may be integrally molded with the curved portions 31, or they may be made of a different material (separate material) from the curved portions 31. When the curved portions 31 and the column portions 33 are made of separate materials, the curved portions 31 and the column portions 33 can be molded from resin material and then combined to obtain the roof 30.

[0050] The edge portion 31a between the column portions 33, 33 in the curved portion 31 (shown in Figures 4, 6, and 7) is curved upward. This allows for a wide space between the upward-curved edge portion 31a in the curved portion 31 and the upper surface of the lid 20, so that, for example, the attractant components contained in the attractant liquid can be diffused around the insect trap 1, and insects can be more easily introduced into the inside of the roof 30. The vertical dimension between the upward-curved edge portion 31a in the curved portion 31 and the upper surface of the lid 20 is preferably 5 mm to 60 mm at its maximum, and more preferably 20 mm to 40 mm. By setting the maximum vertical dimension between the upward-curved edge portion 31a in the curved portion 31 and the upper surface of the lid 20 within this range, insects, especially wasps, can be more easily introduced into the inside of the roof 30. The edge portion 31a between the column portions 33, 33 in the curved portion 31 may be curved in an arc shape or it may be polygonal in shape.

[0051] The column section 33 is plate-shaped and extends vertically. Therefore, when it rains on the upper surface of the curved section 31, the rain naturally flows down along the outer surface of the column section 33. At this time, an overhang section 34 is provided on the roof 30 to prevent rain from falling from parts of the curved section 31 other than the column section 33. The overhang section 34 protrudes outward from the lower edge of the curved section 31 to the roof 30 between adjacent column sections 33 in the circumferential direction and extends in the circumferential direction. In this embodiment, since there are four column sections 33, there are also four overhang sections 34.

[0052] As shown in Figure 2, etc., in a side view of the insect trap 1, the canopy portion 34 is formed so that the center in the left-right direction is the highest point, and it gets lower towards the left and right ends. The left portion of the canopy portion 34 is connected to the column portion 33 located on the left, and the right portion of the canopy portion 34 is connected to the column portion 33 located on the right. Furthermore, the middle portion of the canopy portion 34 is connected to the edge portion 31a of the curved portion 31. Therefore, the canopy portion 34 is the part that integrally connects two adjacent column portions 33, 33 and the curved portion 31 in the circumferential direction. In addition, since the canopy portion 34 protrudes in a direction that intersects with the lower edge of the curved portion 31, it also functions as a rib that reinforces the curved portion 31. Furthermore, since the canopy portion 34 protrudes in a direction that intersects with the side edge of the column portion 33, it also functions as a rib that reinforces the column portion 33.

[0053] The protrusion of the eaves portion 34 can be set to between 0.5 mm and 20 mm. By setting the protrusion of the eaves portion 34 within this range, raindrops are less likely to fall onto the upper surface of the cover 20, and sufficient strength of the roof 30 is obtained. The eaves portion 34 may be provided as needed and may be omitted.

[0054] Two ribs 35 are formed on the inner surface of the roof 30 so as to protrude inward. Each rib 35 extends continuously from the inner surface of one column 33 through the inner surface of the curved section 31 to the inner surface of the other column 33, connecting two diagonally opposite column sections 33, 33. The two ribs 35 intersect each other in the center of the curved section 31. As shown in Figure 4, a suspension section 32 is integrally molded directly above the intersection of the two ribs 35.

[0055] As shown in Figure 8, the lower part of the column 33 has a protruding plate portion 33a that projects radially inward from the roof 30 and extends vertically. The lower edge of the rib 35 is connected to the upper edge of the protruding plate portion 33a, and the protruding plate portion 33a and the rib 35 are integrated. The protruding plate portion 33a is an example of a fitting portion that fits into the container body 10 and restricts the upward displacement of the lid 20.

[0056] Specifically, as shown in Figures 6 and 7, a notch 33b is formed in the protruding plate portion 33a. The notch 33b is open radially inward of the roof 30 and, as shown in Figure 8, has an upper edge portion 33c extending radially outward, a vertical edge portion 33d extending downward from the radially outer end of the upper edge portion 33c, and a lower edge portion 33e extending radially inward from the lower end of the vertical edge portion 33d. The length of the upper edge portion 33c of the notch 33b is set to be longer than the length of the lower edge portion 33e. Also, the radially inner end of the upper edge portion 33c of the notch 33b is located radially inward than the radially inner end of the lower edge portion 33e of the notch 33b. The vertical edge portion 33d is inclined with respect to the vertical line such that it is located radially outward as it goes downward.

[0057] The distance between the upper edge 33c and the lower edge 33e of the notch 33b corresponds to the vertical dimension B1 of the notch 33b. The vertical dimension B1 of the notch 33b is set to be the same as, or slightly longer than, the vertical dimension B2 between the upper surface of the mounting portion 21 of the lid 20 and the lower end surface of the lower extension portion 12a of the container-side extension portion 12. This allows the mounting portion 21 of the lid 20, the lid-side extension portion 22, and the lower extension portion 12a of the container-side extension portion 12 to be placed inside the notch 33b. In other words, the peripheral edge of the container body 10 with the lid 20 placed on it can be fitted inside the notch 33b.

[0058] When the mounting portion 21 of the lid 20, the lid-side extension portion 22, and the lower extension portion 12a of the container-side extension portion 12 are placed inside the notch 33b, the upper edge portion 33c of the notch 33b faces or contacts the upper surface of the mounting portion 21 of the lid 20, the vertical edge portion 33d of the notch 33b faces or contacts the side surface of the lid-side extension portion 22, and the lower edge portion 33e of the notch 33b contacts the lower surface of the lower extension portion 12a of the container-side extension portion 12. Thus, the protruding plate portion 33a having the notch 33b is a portion formed to surround the upper surface of the mounting portion 21 of the lid 20, the side surface of the lid-side extension portion 22, and the lower surface of the lower extension portion 12a of the container-side extension portion 12. This allows the protruding plate portion 33a to be fitted to the container body 10 from the side of the container body 10, and when fitted to the container body 10, the upper edge portion 33c of the notch portion 33b can restrict the upward displacement of the lid 20. To fit it, the roof 30 should be elastically deformed.

[0059] In this embodiment, since there are four columnar sections 33, there are also four protruding plate sections 33a. However, the number of protruding plate sections 33a and the number of columnar sections 33 do not have to be the same; they may be different. For example, protruding plate sections 33a may be provided on three of the four columnar sections 33. Also, the protruding plate sections 33a and the ribs 35 do not have to be continuous. Furthermore, the shape and size of the notch 33b are not limited to the shape shown, and any shape and size that can fit into the container body 10 and restrict the upward displacement of the lid 20 is acceptable.

[0060] (How to use insect trap 1) As described above, the insect trap 1 is stored with the attractant liquid contained in a bag (not shown). The user pours the attractant liquid from the bag into the container body 10 with the lid 20 removed. Then, the user places the lid 20 on the container body 10. At this time, since the lid 20 does not have a fitting structure for the container body 10, the user does not need to perform an operation to fit the lid 20, and only needs to place the lid 20 on the container body 10.

[0061] After placing the lid 20 on the container body 10, the mounting portion 21 of the lid 20, the lid-side extension portion 22, and the lower extension portion 12a of the container-side extension portion 12 are inserted into the inside of the four notches 33b of the roof 30, and the protruding plate portion 33a is fitted into the container body 10. This creates an integrated insect trap 1 consisting of the roof 30, lid 20, and container body 10.

[0062] The insect trap 1 can be used by simply placing it on a table or the like, or by passing a string, thread, wire, etc. through the through hole 32a of the hanging part 32 and hanging it from a tree branch or pole.

[0063] (Effects of the embodiment) As described above, according to the insect trap 1 of this embodiment, when assembling the lid 20 to the container body 10, the upward displacement of the lid 20 is suppressed by fitting the protruding plate portion 33a of the roof 30 to the container body 10 while the lid 20 is placed on top of the container body 10. As a result, a structure for fitting the lid 20 to the container body 10 becomes unnecessary, simplifying the structure and reducing the assembly time by eliminating the step of fitting the lid 20 to the container body 10. Therefore, the assembly time for the user is reduced and assembly is simplified.

[0064] When in use, the attractant components of the attractant liquid contained inside the container body 10 are released to the outside through the inlet hole 20a, attracting insects around the insect trap 1. These insects enter the container body 10 through the inlet hole 20a, fall onto the surface of the attractant liquid, and are captured. If the surface tension of the liquid surface is reduced by the surfactant, insects on the liquid surface will sink into the liquid quickly and will have difficulty escaping through the inlet hole 20a.

[0065] The embodiments described above are merely illustrative in all respects and should not be interpreted restrictively. Furthermore, any modifications or changes that fall within the equivalent scope of the claims are all within the scope of the present invention. For example, the fitting portion may be structured to fit onto the container body 10 by rotating the roof 30, or to fit by hooking a claw-shaped portion onto the container body 10, or to fit by inserting a claw-shaped portion into a fitting hole (not shown) of the container body 10.

[0066] Although not shown in the diagram, the insect trap 1 may also be provided with an impact plate upon which flying insects collide. The impact plate extends vertically and can be installed below the roof 30. The impact plate and the roof 30 may be integrally molded, or they may be separate components. The color, shape, and size of the impact plate can be arbitrarily set. The impact plate may also include multiple plates arranged to intersect each other.

[0067] Figure 9 shows an insect trap 1 according to Modification 1 of the embodiment of the present invention. The roof 30 of the insect trap 1 according to Modification 1 is conical in shape. The outer inclined surface 24 of the lid 20 of Modification 1 has a stepped portion.

[0068] Figure 10 shows an insect trap 1 according to Modification 2 of the embodiment of the present invention. The roof 30 of the insect trap 1 according to Modification 2 is polygonal pyramidal. The outer inclined surface 24 of the lid 20 of Modification 2 also has a stepped portion. The container body 10 of Modification 2 has a polygonal cross-section corresponding to the outer shape of the roof 30. Furthermore, the outer shape of the lid 20 of Modification 2 is also polygonal, corresponding to the outer shape of the roof 30. [Industrial applicability]
