Description

[Technical field]

[0001] The present invention relates to a bedbug trap for trapping bedbugs that breed on beds, sofas, furniture, suitcases, carry cases, sheets, rugs, mattresses, tatami mats, carpets, car seats, etc. [Background technology]

[0002] Bedbugs have traditionally been avoided as harmful animals that suck the blood of humans and warm-blooded animals. Bedbugs are pests that usually spend the day in dark, enclosed places, preferring gaps in beds, sofas, furniture, suitcases, carry cases, and paper, and infiltrate into human living environments. Bedbugs create microenvironments in which they live and lie dormant for long periods within human living environments. These bedbugs are spreading worldwide and gaining momentum. Although adult bedbugs are large enough to be visible (5mm to 8mm), they are difficult to see, highly mobile, and mainly nocturnal, which makes them known to be difficult to find and exterminate. Although bedbugs are pests that need to be exterminated, they are difficult to see with the naked eye because of their small body length and because they hide in beds, furniture, bags, carry cases, blankets, carpets, and other fibers. In addition, bedbugs move from place to place, either by themselves or through contact with people, rather than staying in a fixed nest, making them difficult to exterminate.

[0003] Background Art Bedbug control techniques using a trapping sheet type that holds bedbugs with an adhesive sheet or the like for the purpose of trapping bedbugs are known.

[0004] FIG. 10 is a diagram simply illustrating a bedbug trapping device disclosed in Japanese Patent Application Laid-Open No. 2014-064499, which is related to Patent Document 1. JP 2014-064499 A (Patent Document 4) discloses a pest trap 11 having a structure including a corrugated plate 12 processed into a corrugated shape, and an adhesive body 13 having an adhesive surface and attached to a corrugated protrusion A of the corrugated plate 12 with the adhesive surface facing the corrugated plate 12, with a pest entry section B provided between the adhesive surface of the adhesive body 13 and the corrugated protrusion of the corrugated plate.

[0005] FIG. 11 is a simplified diagram showing a bedbug prevention device disclosed in JP 2015-119681 A of Patent Document 2. JP 2015-119681 A (Patent Document 5) discloses a bedbug control sheet that is characterized by being made of a sheet with a surface static friction coefficient of 0.65 or less, and is configured so that the periphery of the sheet has a rising portion relative to the horizontal surface on which it is placed. This encloses a certain area to prevent bedbugs from entering, creating a so-called safety zone, in which suitcases and traveler luggage are placed.

[0006] FIG. 12 is a diagram simply illustrating the bedbug trapping device disclosed in Patent Document 3, JP 2020-009032 A. In JP2020-009032A (Patent Document 6), a walking pest capture device (1) has a connection part (5) where one end (3a) of an adhesive sheet (3) is connected to one end (4a) of a walking seat (4), a space part (10) for accommodating walking pests B is formed between the adhesive sheet (3) and the walking seat (4), and an entry opening (11) is formed between the other end (3b) of the adhesive sheet (3) and the other end (4b) of the walking seat (4). The structure has a tapered shape in which the separation distance (H) between the adhesive sheet (3) and the walking seat (4) gradually decreases from the entry opening (11) toward the connection part (5). The mechanism works like this: if bed bugs, which love gaps, slip into the tapered gap, they will eventually be captured by the sticky substance placed in the gap.

[0007] FIG. 13 is a diagram simply illustrating a bedbug detection device disclosed in Japanese Patent Application Laid-Open No. 2012-514995 according to Patent Document 4. JP 2012-514995 A (Patent Document 1) discloses a bedbug detection device (10) that includes a hiding place (16) that induces a tactic response from bedbugs, and a non-trapping indicator surface (18) that allows bedbugs to leave behind something that indicates the presence of bedbugs, such as feces or shed skins. This bedbug detection device is not intended to capture and exterminate bedbugs, but is provided as a marker that indicates the presence of bedbugs. When a bedbug moves across the indicator surface on its way to or from a hiding place, it leaves behind something that indicates the presence of bedbugs. In other words, it does not capture the bedbugs themselves, but rather detects the presence of something that serves as an indicator. For example, a marker is attached to the indicator surface, and the presence or absence of a running track of a bedbug on the marker-covered portion is determined.

[0008] FIG. 14 is a diagram simply illustrating a bedbug detection device disclosed in Japanese Patent Application Laid-Open No. 2012-518433 relating to Patent Document 5. JP 2012-518433 A (Patent Document 2) discloses a detection device for monitoring the spread of insects such as bedbugs. The device is equipped with a pair of plates separated by a predetermined distance, and the distance is large enough for a single bedbug to fit in. If the plates are made of a transparent material, the blood feces of bedbugs can be visually observed, and it is possible to determine whether or not bedbugs are present in the environment in which the device is installed.

[0009] FIG. 15 is a diagram simply illustrating a bedbug detection / trapping device disclosed in Japanese Patent Application Publication No. 2013-544514, which is related to Patent Document 6. JP 2013-544514 A (Patent Document 3) discloses a bed bug trap comprising a housing defining a substantially enclosed internal space and a trap, an escape element attached adjacent to the trap defining at least one passage through which bed bugs can move, at least one bed bug attracting element provided within the internal space of the housing, and the trap and / or the escape element. The present disclosure discloses a configuration comprising at least one opening defined in at least one wall of the housing at or adjacent to the element, the trap having a flat recessed area surrounded by at least one wall adapted to capture a bed bug such that if a bed bug enters the trap, the trap limits or prevents escape from the trap.

[0010] [Patent Document 1] JP 2014-064499 A [Patent Document 2] JP 2015-119681 A [Patent Document 3] Special Publication No. 2020-009032 [Patent Document 4] JP 2012-514995 A [Patent Document 5] JP 2012-518433 A [Patent Document 6] Special Publication No. 2013-544514 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0011] The bed bug trap disclosed in Patent Document 1, JP 2014-064499 A, is a corrugated plate (i.e., cardboard material) processed into a corrugated shape, and an adhesive body having an adhesive surface and attached to the corrugated convex part of the corrugated plate with the adhesive surface facing the corrugated plate. If the bed bug enters the opening of the cardboard, it is considered that there is a certain degree of trapping performance. Since the main structure is cardboard, it is difficult to install it in a form that is incorporated into the activity area of ​​the bed bug. Although cardboard is a material that can be easily folded, it is difficult to deform the cardboard so that it is attached to the activity area of ​​the bed bug without any gaps. Even if it is installed near the activity area of ​​the bed bug, the possibility of the bed bug entering such an opening is not high. Therefore, it cannot be said that it is actually an efficient trap for bed bugs.

[0012] Next, the bedbug control sheet disclosed in Patent Document 2, JP 2015-119681 A, creates a safety zone around the target object, such as a suitcase, by placing a paper-like sheet around it to prevent bedbugs from entering inside, but it does not exterminate or capture bedbugs. This does not ensure human activities in the human living environment, and only serves as a measure to prevent bedbugs from entering the belongings of travelers staying at hotels for a short time.

[0013] Next, the bed bug capture device disclosed in Patent Document 3, JP 2020-009032 A, is a capture device in which a taper is attached between two plates, and when a bed bug inside the taper invades, the height gradually decreases due to the taper, and the device adheres to the back of the bed bug and captures it. If the bed bug invades the gap of the taper as intended, it is considered that there is a certain degree of capture performance. The plate-shaped material is arranged in a hinged manner at a taper angle, and it is not easy to bend it, and it is difficult to deform it so that it can be attached without gaps to the activity area of ​​the bed bug. In addition, since it is assumed that it will be placed directly on the floor, it occupies part of the room and deteriorates the living environment of humans. Furthermore, even if it is installed near the activity area of ​​the bed bug, the possibility of it conveniently invading such a taper is not high. Therefore, it cannot actually be said to be something that efficiently captures bed bugs.

[0014] The bedbug detection device disclosed in Patent Document 4, JP 2012-514995 A, and the bedbug detection device disclosed in Patent Document 5, JP 2012-518433 A, are capable of recognizing whether or not bedbugs are present in the environment, but do not disclose how to exterminate or capture them, and it is assumed that they will be sprayed with highly toxic chemicals such as insecticides. Such spraying of insecticides is harmful to humans as well, and is not a desirable solution. In recent years, bedbugs that are resistant to insecticides have appeared, and it is assumed that spraying of insecticides will not be sufficient to exterminate them.

[0015] Next, the bedbug detection / trapping device disclosed in Patent Document 6, JP Patent Publication No. 2013-544514, is considered to have a certain degree of trapping performance if the bedbug enters the trap opening of the trap as intended. In particular, the trap is mainly made of cardboard. However, it is difficult to install it in a way that is incorporated into the bedbug's activity area, and even if it is installed near the bedbug's activity area, the possibility that the bedbug will conveniently enter such a trap is not high. Therefore, it cannot actually be said to be a device that efficiently traps bedbugs.

[0016] In order to solve the above problems, the present invention aims to provide a three-dimensional bedbug trap that is easy to attach to appropriate locations that are activity environments for bedbugs based on their natural nature (for example, the base of the legs of a bed, the top or bottom of a bed headboard, the top or bottom of a bed footboard, the top or bottom of a bed side frame, the gaps in the bed side frame, between the bedside frame and the mattress, the edge of furniture, the base of the legs of a sofa, between the seat and back of a sofa, the frame of a picture, the top or bottom of a trash can, around an electrical outlet, etc.), and that can be placed in a location that bedbugs will naturally be forced to enter as they continue their activity based on their natural nature, guiding them into an escape-proof space formed by the main body of the three-dimensional structure and the three-dimensional mesh, and ultimately preventing bedbugs from escaping once captured by the adhesive components. [Means for solving the problem]

[0017] The three-dimensional bedbug trap of the present invention comprises a three-dimensional passage layer made of a porous material having pores large enough for bedbugs to pass through, and a three-dimensional adhesive layer formed by impregnating the interior of the three-dimensional passage layer with an adhesive for capturing bedbugs, and is characterized in that the three-dimensional adhesive layer captures the bedbugs that have entered the interior of the three-dimensional passage layer from the outer surface thereof.

[0018] Here, the three-dimensional structure adhesive layer is formed by impregnating the material of the three-dimensional structure transit layer with an adhesive. It is preferable that the three-dimensional adhesive layer is not exposed on the outer surface of the three-dimensional passage layer, and that the bedbug penetrates into the three-dimensional adhesive layer until a part of the body of the bedbug is captured by the adhesive of the three-dimensional adhesive layer and cannot move. In this way, the back and torso of the bedbug are captured by the thread-like walls and pillars that form a mesh in the three-dimensional structure, and the bedbug can no longer move by its legs and cannot escape.

[0019] The three-dimensional bedbug trap of the present invention may be simply placed on the floor, but is preferably attached to the installation location. This is because, as mentioned above, bedbugs do not move in a two-dimensional manner, but move freely around beds and furniture to move three-dimensionally.

[0020] As an ingenious feature, the three-dimensional bedbug trap of the present invention is structured to include a main attachment section that attaches and fixes part of the main body of the three-dimensional structure to the object to be protected, such as furniture or a bed, or to the surrounding wall surface, a three-dimensional mesh body extending from the outer surface of the main body of the three-dimensional structure, and a sub-attachment section that attaches and fixes a portion of the three-dimensional mesh body near its tip to the object, such as furniture or a bed, or to the surrounding wall surface. Here, the three-dimensional mesh body is a structure comprising a first three-dimensional mesh body portion with a hole size that bedbugs cannot pass through, and a second three-dimensional mesh body portion with a hole size that bedbugs can pass through, and a secondary attachment portion is provided near the tip of the second three-dimensional mesh body portion for attaching and fixing to furniture, beds, etc. By adjusting the pore size of the three-dimensional mesh body in this manner, the tip of the second three-dimensional mesh body portion can be attached and fixed to furniture, a bed, etc. by the sub-attachment portion. In other words, if the end of the second three-dimensional net part is attached to the path of the bed bug in its activity range, the bed bug will naturally pass through the second three-dimensional net part and enter the internal space. Since it is a three-dimensional net, the attachment shape can be freely changed and it can be attached to the shape of an object such as furniture. If a bed bug that naturally walks in its original activity range continues walking after entering the interior, it will naturally be led to the first three-dimensional net, but the hole diameter of the first three-dimensional net is such that the bed bug cannot pass through, and it will no longer be able to escape to the outside. The main body of the three-dimensional structure attached by the main attachment part is waiting in front. Since it is the original activity area, many bed bugs will enter the main body of the three-dimensional structure as it is and be captured by the adhesive of the three-dimensional structure adhesive layer inside.

[0021] Here, various materials can be used as the material for the three-dimensional structure, and examples of such materials include one or more three-dimensional fibrous porous bodies selected from the group consisting of urethane foam (sponge), double russell, nonwoven fabric, cotton, gauze, etc. For example, urethane foam (sponge) is a porous body with an open-cell structure. The pore size of the open-cell structure is preferably 3 mm to 10 mm, so that bedbugs can pass through. In addition, other three-dimensional structures such as double raschel, nonwoven fabric, cotton, and gauze are also preferably porous bodies having pores with a size that allows bedbugs to pass through.

[0022] No adhesive is applied to the outside of the three-dimensional structure passing layer, but the three-dimensional structure adhesive layer is present inside. This three-dimensional adhesive layer has a significantly increased adhesive surface area compared to conventional bed bug repellent sheets. Conventional bed bug repellent sheets only have a single layer of adhesive surface, so the adhesive surface area is only the surface area of ​​the adhesive surface. On the other hand, in the three-dimensional bed bug trap of the present invention, the three-dimensional adhesive layer is a three-dimensional structure impregnated with an adhesive, and the skeletal structure itself has adhesiveness, so the area is significantly increased in three dimensions. It is preferable that the three-dimensional adhesive layer contains an attractant, in order to encourage the bedbugs to enter the interior of the bed.

[0023] Next, the installation (attachment) state of the three-dimensional bedbug trap of the present invention, in particular the ingenuity of the three-dimensional shape of the three-dimensional netting extending from the main body of the three-dimensional structure, will be described. The overall shape of the first three-dimensional mesh body is arranged so that the overall shape of the three-dimensional mesh body is a funnel, with the spindle portion of the funnel being the first three-dimensional mesh body portion and the tip portion of the funnel being the second three-dimensional mesh body portion. With the above configuration, bedbugs are guided from the outer surface side to the inner surface side in the second three-dimensional mesh body at the tip of the funnel, and when the bedbugs reach a bed, furniture, etc. on the inner surface side and move further, they are captured in the space surrounded by the first three-dimensional mesh body and the main body of the three-dimensional structure.

[0024] The overall shape of the second three-dimensional mesh body is such that the shape of the three-dimensional mesh body as a whole is that of a cast net, with the main body of the three-dimensional structure located in the central part of the cast net, a first three-dimensional mesh body portion extending radially from the main body of the three-dimensional structure, and a second three-dimensional mesh body portion provided at the tip side of the first three-dimensional mesh body portion, and the vicinity of the tip of the second three-dimensional mesh body portion is positioned by the secondary attachment portion. With the above configuration, the second three-dimensional netting section can be freely deformed into a straight or curved shape and attached along furniture, beds, etc. With this arrangement, the second three-dimensional netting section, which is the tip of the casting net, guides bedbugs from the outer surface side to the inner surface side, and when the bedbugs reach the furniture, bed, etc. on the inner surface side and move further, they are captured in the space surrounded by the first three-dimensional netting section and the main body of the three-dimensional structure.

[0025] In addition, it is preferable that a plurality of return members are provided on the inner surface of the first three-dimensional mesh body to prevent bedbugs that have passed through the second three-dimensional mesh body and entered the internal space from moving backwards and escaping. In other words, it is preferable to have a structure like a fish cage in which bedbugs can enter forward but have difficulty moving backwards, and thus not be allowed to escape backwards.

BEST MODE FOR CARRYING OUT THEINVENTION

[0027] Hereinafter, an embodiment of the three-dimensional bedbug trap of the present invention will be described. Note that the following embodiment is merely an example and does not limit the technical scope of the present invention. Example 1

[0028] A configuration example of a three-dimensional bedbug trap according to a first embodiment of the present invention will be described below. FIG. 1 is a simplified diagram illustrating the structure of a three-dimensional bedbug trap according to a first embodiment of the present invention. Fig. 1(a) is a perspective view of a three-dimensional bedbug trap 100, and Fig. 1(b) is a schematic enlarged view of a three-dimensional passage layer 110 and a three-dimensional structure adhesive layer 120. The drawings are very simplified for ease of understanding. As shown in FIG. 1, the three-dimensional bed bug trap 100 of the present invention is configured with three-dimensional passage layers 110a and 110b and a three-dimensional structural adhesive layer 120 sandwiched between the three-dimensional passage layers 110a and 110b.

[0029] The three-dimensional passage layers 110a and 110b are structures with pores large enough for bedbugs to pass through, and are located on the front and back of the three-dimensional adhesive layer 120. They allow bedbugs to pass through to the inside and also serve to prevent the three-dimensional adhesive layer 120 from being exposed.

[0030] The material of the three-dimensional passage layers 110a and 110b is not particularly limited as long as it is a porous material, for example, a three-dimensional open-cell material or a three-dimensional fibrous material. Specific examples of three-dimensional open-cell foams include urethane foam, rubber foaming agent foam, melamine foam, EVA sponge foam, etc. As for the material of the porous body, other materials may be used as long as they have the foaming performance to create a porous body with an appropriate open-cell structure. Specific examples of three-dimensional fibrous bodies include double raschel, nonwoven fabric, felt, woven fabric, cotton, gauze, paper, etc. Other materials may be used as long as they are three-dimensionally combined fibrous materials. It may be a single material or a combination of multiple materials. It may be a single-layer thick one or a multiple-layer one. The example in Figure 1 is a simplified diagram of a sponge-like open-cell porous body.

[0031] The pore size of the porous three-dimensional structure is preferably 3 to 10 mm, although some pores may have larger or smaller diameters. There are various types of bedbugs, including the bedbug Cimex lectularius and the Taiwanese bedbug, but these types of bedbugs are roughly the same size as adults, about 5 to 8 mm. The appropriate hole size for these adults to easily enter is 5 to 10 mm. If you take into consideration measures against larvae, it is fine for some of the holes to be about 3 to 5 mm in diameter.

[0032] The three-dimensional adhesive layer 120 is a three-dimensional adhesive layer for capturing bedbugs provided inside the three-dimensional passage layer 110, and is sandwiched between the three-dimensional passage layers 110a and 110b. That is, as shown in FIG. 1, the three-dimensional adhesive layer 120 for capturing bedbugs is formed inside the three-dimensional structure without being exposed on the outer surface. For example, the three-dimensional structure adhesive layer 120 is formed by impregnating the material of the three-dimensional passage layers 110a and 110b with an adhesive. Since the three-dimensional passage layers 110a and 110b are porous bodies, an adhesive layer with a three-dimensional structure can be formed by impregnating them with an adhesive. In other words, the three-dimensional structure adhesive layer 120 is a three-dimensional structure of a porous body of about 3 to 10 mm, and the three-dimensional structure itself, which is the skeleton of the layer, has adhesiveness.

[0033] The type of adhesive is not particularly limited and may be acrylic, styrene, rubber, silicone, rosin, urethane, etc., but for example, an acrylic adhesive containing an acrylic acid ester copolymer can be used.

[0034] The acrylic acid ester copolymer includes an acrylic triblock copolymer and an acrylic diblock copolymer. The acrylic pressure-sensitive adhesive may consist of only the above-mentioned triblock copolymer, but may also contain other components as appropriate. From the viewpoint of obtaining a pressure-sensitive adhesive having good compatibility with the triblock copolymer, improved uniformity, and superior heat resistance and weather resistance, the components that may be contained in the acrylic pressure-sensitive adhesive include acrylic diblock copolymers, tackifiers, etc. The diblock copolymer may have a functional group such as a hydroxyl group, a carboxyl group, an acid anhydride group, an amino group, or a trimethoxysilyl group in the molecular side chain or at the molecular main chain terminal, if necessary.

[0035] Furthermore, in order to improve and easily adjust tack, adhesive strength, and retention, it is preferable to blend a tackifier into the acrylic adhesive. Examples of tackifiers that can be blended include rosin derivatives such as rosin ester, gum rosin, tall oil rosin, hydrogenated rosin ester, maleic rosin, and disproportionated rosin ester, terpene phenol resins, terpene resins mainly composed of α-pinene, β-pinene, and limonene, (hydrogenated) petroleum resins, coumarone-indene resins, hydrogenated aromatic copolymers, styrene resins, phenolic resins, and xylene resins. These can be used alone or in combination of two or more.

[0036] The presence or absence of the diblock copolymer, triblock copolymer, and tackifier and the blending ratio can be appropriately selected depending on the application of the adhesive product, the type of adherend, etc., and is not particularly limited. The pressure-sensitive adhesive may be an emulsion type pressure-sensitive adhesive or a hot-melt type pressure-sensitive adhesive.

[0037] Such adhesive is impregnated into the material of the three-dimensional passage layers 110a and 110b. If the amount of impregnation is too small, the effect is small, and if the amount is too large, the adhesive will crush the mesh of the three-dimensional passage layers 110a and 110b and the three-dimensional mesh structure cannot be maintained. Therefore, the amount of impregnation is set to a level that will reach the walls and columns of the three-dimensional mesh structure such as urethane but will not fill the gaps between the squares. For example, the amount of impregnation is set to a range of 10 to 200 g / m2.

[0038] The adhesive needs to remain in a three-dimensional mesh structure such as urethane, so if the viscosity is too low, it may flow out, and if the viscosity is too high, it becomes difficult to apply and the adhesive layer does not spread evenly over the entire three-dimensional structure adhesive layer 120. Therefore, the viscosity is set to a level that does not easily flow out of the three-dimensional mesh structure and is suitable for application.

[0039] The adhesive may be applied by any method, but for example, the adhesive may be applied by using a printing technique in the manner of silk screen printing. In other words, the adhesive is treated as a silk screen ink and is uniformly applied to the surfaces of the three-dimensional passage layers 110a and 110b in the manner of printing the adhesive on the surfaces. In this case, the manufacturing method of the three-dimensional structure adhesive layer 120 is to press the three-dimensional passage layer 110a and the three-dimensional passage layer 110b, which have adhesive printed on their surfaces, together to bond them together to produce the three-dimensional structure adhesive layer 120. As an application method, instead of silk screen printing, a method of continuously applying the coating material to the roll-shaped three-dimensional passage layer 110a and the three-dimensional passage layer 110b using a roller is also possible.

[0040] The three-dimensional adhesive layer 120 has a significantly increased adhesive surface area compared to conventional bedbug-proof sheets. In this example, the three-dimensional adhesive layer 120 has a sponge-like open-cell structure, which is a three-dimensional mesh structure, and the skeletal structure of the layer has adhesive properties, so the area is significantly increased in three dimensions. In addition, as described above, the three-dimensional structure adhesive layer 120 has many gaps of about 300 to 3000 μm formed therein, so that the three-dimensional structure adhesive layer 120 has a structure that allows a bedbug to penetrate into the three-dimensional structure adhesive layer until part of the bedbug's body is captured by the adhesive and cannot move.

[0041] The three-dimensional structural adhesive layer 120 preferably contains bait to attract bedbugs. The bait for attracting bedbugs is not limited as long as it is what the bedbugs like. For example, the attractant may be nonanal, 1-octan-3-ol, spearmint oil, coriander oil, etc., and may further be an aldehyde compound, a ketone compound, a histamine compound, etc. Since the three-dimensional adhesive layer 120 contains bait, the bedbugs are attracted toward the three-dimensional adhesive layer 120. The above is a description of the configuration of each part of the three-dimensional bedbug trap 100 of the present invention.

[0042] Fig. 2 is a diagram showing a bedbug trapped in the prototype three-dimensional bedbug trap of the present invention. The diagram is a simplified enlarged view. The magnification is 50 times. In the example in Figure 2, the material used is urethane foam. The adhesive used was selected from acrylic ester polymers. Thus, it can be seen that the three-dimensional bed bug trap 100 of the present invention shown in FIG. 2 has the effect of trapping bed bugs.

[0043] Next, the process of trapping bedbugs using the three-dimensional bedbug trap 100 of the present invention will be described. FIG. 3 is a diagram for simply explaining the process of trapping bedbugs when the three-dimensional bedbug trap 100 of the present invention is used. The three-dimensional bedbug trap 100 of the present invention can be installed anywhere bedbugs are expected to inhabit, such as beds, sofas, furniture, suitcases, carry-on cases, sheets, rugs, mattresses, tatami mats, carpets, car seats, etc. When the three-dimensional passage layers 110a and 110b on the front or back surface of the three-dimensional bedbug trap 100 of the present invention are provided with an adhesive that can be applied, the trap can be applied simply by placing it on the surface.

[0044] Bedbugs live and move around in large numbers in the installation area. Since the three-dimensional adhesive layer 120 contains bait, the bedbugs are attracted toward the three-dimensional adhesive layer 120. Bedbugs first attach to the surfaces of the three-dimensional passage layers 110a and 110b on the front or back side of the three-dimensional bedbug trap 100, and then invade the inside from the surfaces of the three-dimensional passage layers 110a and 110b. As described above, the three-dimensional passage layers 110a and 110b have a three-dimensional porous structure with continuous pores having a diameter of about 3 to 8 mm, so that it is possible to penetrate into the interior of the three-dimensional passage layers 110a and 110b through the gaps.

[0045] Eventually, the bedbugs pass through the three-dimensional passage layers 110 a and 110 b and reach the three-dimensional structural adhesive layer 120 . The bedbugs reach the three-dimensional adhesive layer 120, but since the three-dimensional adhesive layer 120 is also a porous three-dimensional adhesive layer similar to the three-dimensional passage layers 110a and 110b, they continue to invade into the three-dimensional adhesive layer 120 until they are captured by the adhesive and can no longer move.

[0046] Then, as the bedbug that has invaded the inside of the three-dimensional adhesive layer 120 walks around or tries to go back, parts of the bedbug other than the legs, such as its back, sides of its body, and head, come into contact with the skeletal structure of the sticky three-dimensional adhesive layer, and those parts other than the legs become trapped and are unable to move. Conventional bedbug trapping sheets are flat and only capture the legs of bedbugs, which only capture a small part of the body, and the bedbugs may eventually break away and escape, but the three-dimensional bedbug trap 100 of the present invention has a structure impregnated with adhesive in all directions in three dimensions for bedbugs that have invaded the inside of the three-dimensional adhesive layer 120, making it possible to trap them with the adhesive from all directions. In particular, when the back of a bedbug is captured by the adhesive, the adhesive surface area is large and the legs are in the air, meaning that they cannot brace themselves, and once captured by the adhesive, the bedbug has no way to escape and remains trapped until it is killed.

[0047] 3(b) is an enlarged view of a portion of the three-dimensional adhesive layer 120, and is a simplified diagram showing a state in which a bedbug is trapped and unable to move after its back or torso is stuck to a part of the porous three-dimensional adhesive layer 120. When the back or torso of a bedbug sticks to a part of the open-cell foam of the three-dimensional adhesive layer 120, its legs are in the air above the foam, meaning that it is unable to escape even if it thrashes its legs around. The above is an explanation of the process of trapping bedbugs when using the three-dimensional bedbug trap 100 of the present invention.

[0048] Next, a brief example of installation of the three-dimensional bed bug trap 100 of the present invention will be given. 4 and 5 are simplified diagrams showing examples of the operation and state of installation of the three-dimensional bed bug trap 100 of the present invention. The example of Figures 4 and 5 is an example in which a three-dimensional bedbug trap 100 is attached to a leg 210 of a table 200, and the main body 130 of the three-dimensional bedbug trap 100 is attached near the base of the leg under the seat of the table via the main attachment part 131A.

[0049] In this example, the main attachment part 131A of the main body part 130 of the three-dimensional bedbug trap 100 is provided on a surface facing the bottom surface of the seat of the table 200 in the figure. In addition, the main attachment part 131 is not only provided on one surface, but also on a surface that comes into contact with each other as the three-dimensional bedbug trap turns, as shown in Figures 4(a) and 4(b), so that the main body part 130 of the three-dimensional bedbug trap can easily maintain the turning state. In other words, as shown in FIG. 4(b), when the main body 130 of the three-dimensional bedbug trap is brought into contact with the bottom surface of the seat of the table 200 from below to above, the main attachment portion 131A comes into contact with and is attached to the bottom surface of the seat of the table 200. As shown in FIG. 4( a ), the main body 130 of the three-dimensional bedbug trap is attached to the bottom surface of the seat of the table 200 by abutting it thereon, and is then wrapped around the legs 210 of the table 200 .

[0050] FIG. 5 shows the three-dimensional bedbug trap 100 in an installed state. 5(a) and 5(b), the main body 130 of the three-dimensional bedbug trap 100 is installed around the periphery of the leg 210 of the table 200. It is firmly adhered and fixed by the main attachment part 131A. In this example, a main attachment portion 131B is also provided to facilitate maintaining the main body 130 of the three-dimensional bedbug trap 100 in an orbital state, and the trap is stably installed while maintaining the orbital state.

[0051] The three-dimensional bedbug trap 100 of the present invention is not limited to being attached to the legs 210 of the table 200, but can also be attached to a wide variety of objects and surrounding wall surfaces. While the possible states are endless, the three-dimensional bedbug trap 100 of the present invention can be attached to the top surface of an object, the side wall surface of an object, or the underside of an object. FIG. 6 is a simplified diagram illustrating various possible orientations of the three-dimensional bedbug trap 100 of the present invention relative to an object 200. As shown in FIG. FIG. 6(a) shows the state when pasted on the top surface of object 200, FIG. 6(b) shows the state when pasted on the side wall surface of object 200, and FIG. 6(c) shows the state when pasted on the bottom surface of object 200. In this manner, the three-dimensional bedbug trap 100 of the present invention can be attached to a wide variety of objects 200 and surrounding wall surfaces. Example 2

[0052] A configuration example of a three-dimensional bedbug trap according to a second embodiment of the present invention will be described below. The three-dimensional bed bug trap 100A of the present invention according to the second embodiment is configured to include a net body 140 in addition to the main body 130 including the three-dimensional passage layer 110 and the three-dimensional structure adhesive layer 120 shown in the first embodiment. The three-dimensional bed bug trap 100A can be freely installed in the bedbug activity environment by changing its shape to suit the bedbug activity environment.

[0053] The mesh body 140 includes a first mesh body portion 141 having a hole size that bedbugs cannot pass through, a second mesh body portion 142 having a hole size that bedbugs can pass through, and a secondary attachment portion 143.

[0054] FIG. 7 is a diagram simply illustrating an example of an installation state of a three-dimensional bedbug trap 100A according to the second embodiment of the present invention. The example in Figure 7 is similar to the installation example shown in Figures 4 and 5 in Example 1, i.e., an example in which a three-dimensional bedbug trap 100A is attached to a table, but shows how a net body 140 is used. In addition, in Figs. 7(a) and 7(b), the main body 130 of the three-dimensional bedbug trap 100A hidden below the net body 140 is shown in a see-through manner.

[0055] As in Figures 4(b) to 5(b) in the above-mentioned Example 1, when the three-dimensional bedbug trap 100A is wrapped around the legs 210 of the table 200, as shown in Figures 7(a) to 7(b), the mesh body 140 also moves around, and as shown in Figure 7(b), the main body 130 is attached via the main attachment part 131 near the base of the legs 210 under the seat of the table 200, the mesh body 140 is attached along the legs 210, and the secondary attachment part 143 near the tip of the second mesh body part 142 is attached and fixed to the tip of the leg.

[0056] In the example of Figure 7, the overall shape of mesh body 140 is funnel-shaped, with the spindle part of the funnel being first mesh body part 141 and the area near the tip of the funnel being second mesh body part 142, the most distal part of which is attached to the tip of a table leg by secondary attachment part 143. In other words, the shape of the mesh body 140 as a whole is funnel-shaped, and at the top of the funnel is the main body 130 of the three-dimensional structure shown in Example 1, and overall a funnel-shaped space is formed surrounded by the second mesh body portion 142, the first mesh body 141, and the main body 130.

[0057] Here, the second mesh body 142 at the tip of the funnel has a hole size that allows bedbugs to pass through, and they can enter by passing from the floor surface where they are active, i.e., from the outer surface side to the inner surface side.When a bedbug reaches a table leg and climbs upward, or when a bedbug climbs upward on the inner surface side of the second mesh body 142, it is surrounded by a space enclosed by the first mesh body 141 and the main body 130. Bedbugs have the tendency to move toward the base of a table, which is their natural habitat, and so they invade toward the three-dimensional bedbug trap 100A of the present invention described in the first embodiment.

[0058] Here, the tip side of the net body 140 is provided with a second net body 142 with a hole diameter that allows the bedbug to pass through, allowing the bedbug to enter the trap from the outside, and when the bedbug enters the inside through the second net body 142 and moves upward, it is unable to escape to the outside due to the first net body 141 with a hole diameter that the bedbug cannot pass through, and the bedbug is surrounded and captured in the funnel-shaped space surrounded by the first net body 141 and the main body 130. Eventually, the bedbug, based on its natural nature, passes through the three-dimensional passing layer 110 of the main body 130 that is affixed to the leg of a table, which is its natural habitat, and is eventually captured in the three-dimensional structure adhesive layer 120.

[0059] In this manner, by using the three-dimensional bedbug trap 100A of the second embodiment, a trap for bedbugs can be easily formed, so to speak, as shown in FIG. The three-dimensional bedbug trap 100A of the second embodiment can be installed in a variety of shapes, not limited to a funnel shape as shown in FIG. In other words, in the three-dimensional bedbug trap 100A of Example 2, the main body 130 itself can be freely attached up, down, left and right using the main attachment part 131, and further, the mesh body 140 extending from the outer surface of the main body 130 of the three-dimensional structure can be expanded and installed so as to surround the movement path of the bedbugs.

[0060] For example, the net body 140 is installed in a shape similar to a cast net. The main body 130 of the three-dimensional bedbug trap 100A is located in the center of the cast net, and the three-dimensional bedbug trap 100A has a first mesh body portion 141 that extends radially from the main body 130, and a second mesh body portion 142 is provided at the tip side of the first mesh body portion 141, and the second mesh body portion 142 is fixed by a secondary attachment portion 143.

[0061] FIG. 8 is a diagram simply illustrating an example of an installation state of a three-dimensional bedbug trap 100A according to a second embodiment of the present invention, in which the trap is shaped like a cast net. The example in Fig. 8 shows an example in which the three-dimensional bedbug trap 100A according to the second embodiment is attached along the edge of the side frame 200 of the bed to be protected. Fig. 8(a) shows the state in which the main body 130 is attached to the outer surface side of the bedside frame 200 via the main attachment part 131, and the net body 140 is spread along the side frame 200 of the bed. Fig. 8(b) shows a simple side view of the state. The first net body part 141 is spread out like a cast net along the side frame 200 of the bed, and a second net body part 142 is provided at its tip, and a sub-attachment part 143 near the tip is attached and fixed to the edge of the side frame of the bed.

[0062] 8(b), the net body 140 is spread out like a curtain from the outer surface of the main body 130 like a cast net, the first net body 141 is hung from the main body 130 and spread out like a plane, the second net body 142 is below it, and the lower end of the net body 140 has a sub-attachment body 143, which is attached in a line to the lower part of the wall surface. Therefore, a bedbug that has come from below enters the inner surface side from the second net body 142 and further climbs upward, and is captured in the space surrounded by the first net body 141 and the main body 130, and is finally captured by the three-dimensional structure adhesive layer 120 of the main body 130.

[0063] Figure 8 shows an example of the trap being attached to the side frame of a bed, but the objects to be protected can include a variety of objects that are habitats for bedbugs, such as furniture, beds, sofas, suitcases, carry-on cases, sheets, rugs, mattresses, tatami mats, carpets, car seats, etc., and the trap can be attached to the floor, ceiling, or wall around the object. The second mesh body portion 142 can be attached in a straight or curved shape via the secondary attachment portion 143, and the second mesh body portion 142 at the tip of the casting net guides bedbugs from the outer surface side to the inner surface side, and when the bedbugs reach the object to be protected, such as furniture, on the inner surface side and move further, they are captured in the space surrounded by the first mesh body 141 and the main body 130.

[0064] In other words, the example shown in Figure 8 is a trap that spreads out like a cast net, and a bedbug that gets inside the trap will eventually, based on its natural properties, reach the main body 130 that is attached to an object, which is its natural habitat, pass through the three-dimensional passage layer 110, and eventually be captured in the three-dimensional structure adhesive layer 120.

[0065] Fig. 9 is a diagram simply illustrating the so-called "return structure" provided on the inner surface side of the first net body 141. Fig. 9 shows the first net body 141 in vertical section, with the "return structure" exaggerated and enlarged for easy understanding. The "return structure" is a cilia tilted in one direction, and the presence of this "return structure" makes it difficult for bedbugs to move backwards and escape to the bottom, in addition to their tendency to climb upwards, so that they are always guided to move toward the main body 130.

[0066] While a preferred embodiment of the three-dimensional bed bug trap of the present invention has been shown and described, it will be understood that various modifications can be made therein without departing from the spirit and scope of the invention. [Industrial Applicability]

[0067] The three-dimensional bedbug trap of the present invention can be provided as a bedbug trapping sheet for trapping bedbugs. It can be placed on objects that are in the environment where bedbugs are active based on their natural nature, such as the base of the legs of a bed, the top and bottom ends of a headboard of a bed, the top and bottom ends of a footboard of a bed, the top and bottom ends of a side frame of a bed, the gap between the side frame of a bed, between a bedside frame and a mattress, the edge of furniture, the base of the legs of a sofa, between the seat and back of a sofa, the frame of a picture, the top and bottom ends of a trash can, around an electrical outlet, etc. Also, a trap can be freely formed and provided that surrounds the bedbugs so that they cannot escape when they perform activities based on their natural characteristics.
