Description

[Technical Field]

[0001] The present invention relates to a cockroach trap for capturing cockroaches. In particular, it relates to a three-dimensional cockroach trap with a three-dimensional structure that captures the three-dimensional movements of cockroaches, rather than the flat cockroach trap sheets that are placed on floors or walls as seen in the prior art. [Background technology]

[0002] Known examples of conventional pest traps include those disclosed in Patent Document 1 (JP Patent Publication No. 10-165069) and Patent Document 2 (JP Patent Publication No. 11-000092). These traps are similar to the cockroach trap shown in FIG. As shown in Figure 9, the device comprises a main body 1 made of a sheet material such as cardboard, which is folded and assembled into a horizontally elongated hollow cylinder with a trapezoidal cross section. End openings 4a, 4b are provided at both axial ends of the main body 1, and side openings 6a, 6b are provided on both side surfaces. A transparent or translucent adhesive layer 2 is applied to the entire bottom surface 3 of the main body 1. An attractant is disposed in the center. With this configuration, cockroaches enter the device from the outside through the end openings 4a, 4b or the side openings 6a, 6b, are attracted by the attractant, and enter the adhesive layer 2, where they are trapped by its adhesive properties.

[0003] Further, as a conventional pest trap, for example, one disclosed in Patent Document 3 (Japanese Patent Laid-Open Publication No. 2006-325472) is known, which is, for example, a cockroach trap as shown in FIG. As shown in Figure 10, this cockroach trap consists of a bottom wall 1, side walls 2 and 3, and top walls 4 and 5. The side walls 2 and 3 are folded to fold the trap body flat, and the side walls 2 and 3 are stretched to assemble the trap body into a three-dimensional shape. An adhesive layer X for catching cockroaches is formed on the upper surface of the bottom wall 1, and release paper Y for protecting the adhesive layer is adhered to the underside of the top wall, and the adhesive strength of the release paper Y to the top walls 4 and 5 is stronger than that to the adhesive layer. The technology of Patent Document 3 simplifies the assembly process compared to the prior art technologies of Patent Documents 1 and 2. In other words, assembly can be completed with just one action of separating the top walls 4 and 5 from the bottom wall 1, and the release paper Y is also peeled off during the assembly of the trap body, making assembly of the cockroach trap easy.

[0004] Further, as a conventional pest trap, for example, one disclosed in Patent Document 4 (JP 2019-126288 A) is known, such as the cockroach trap shown in FIG. As shown in Figure 11, the cockroach trap 1 shown in Patent Document 4 has a three-dimensional main body 2 with a box-like internal space capable of accommodating cockroaches, and an opening 3 that allows cockroaches to enter the internal space from the outside is provided in the main body 2. The opening 3 is configured to open to the outside in only one direction (rearward) on the main body 2. The technology of Patent Document 4 reduces discomfort to the user (installer) compared to the conventional technologies of Patent Documents 1 and 2. In other words, because the opening 3 is configured to open to the outside in only one direction, cockroaches are difficult to see from the outside even when cockroaches are contained in the internal space, and therefore it is believed that this makes it difficult to cause discomfort to the user.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-165069 [Patent Document 2] Japanese Patent Application Publication No. 11-000092 [Patent Document 3] Japanese Patent Application Laid-Open No. 2006-325472 [Patent Document 4] Japanese Patent Application Publication No. 2019-126288 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0006] The cockroach traps of the prior art described in Patent Document 1 (JP Patent Publication No. 10-165069), Patent Document 2 (JP Patent Publication No. 11-000092), Patent Document 3 (JP Patent Publication No. 2006-325472), and Patent Document 4 (JP Patent Publication No. 2019-126288) are all box-assembly type devices with flat catching surfaces, and the surface is simply coated with a sheet of adhesive, so the catching power is insufficient and cockroaches often escape.

[0007] The first problem with the above-mentioned prior art is that cockroaches that have entered the box often become wary when they come into contact with the adhesive and escape from the box. Also, if the adhesive sheet is flat, the cockroach's body is not directly touched and is not sufficiently captured, and if only the legs are touched, the cockroach will tear off its own legs and escape.

[0008] The second problem with the above-mentioned conventional technologies is that the adhesive weakens in wet environments. Because the adhesive is simply applied to the surface in a sheet form, all of the above-mentioned conventional technologies are likely to get wet in wet areas, which can easily cause the adhesive's adhesive strength to deteriorate. This limits the locations where they can be installed.

[0009] The third problem with the above-mentioned conventional technologies is that, because they are all formed by assembling a box, the size of the box is predetermined and cannot be freely changed, which limits the location and orientation of the device. On the other hand, cockroaches have three-dimensional paths, often passing through narrow gaps in walls and furniture, making the cockroach traps of the above-mentioned conventional technologies difficult to install.

[0010] The fourth problem with the above-mentioned prior art is that the box has a flat adhesive sheet on the bottom, and its position cannot be changed dynamically, so it must be installed in a basic position so that the bottom is parallel to the floor. For example, even if it is installed on the wall, cockroaches move freely inside the box, so there is a problem that they pass through the sides and top of the box, which do not have an adhesive sheet.

[0011] In order to solve the above problems, the present invention aims to provide a three-dimensional cockroach trap that can respond to the three-dimensional movements of cockroaches, has three-dimensional structural components, and uses an adhesive trap layer to prevent cockroaches from escaping once they have been captured. [Means for solving the problem]

[0012] The three-dimensional cockroach trap of the present invention is characterized by a three-dimensional structure that is a solid, continuous mesh, open-cell, or continuous lattice structure, and a three-dimensional trap layer that contains an adhesive for capturing cockroaches inside the three-dimensional structure and captures adult cockroaches with the adhesive.

[0013] With the above-mentioned configuration, unlike conventional cockroach traps with flat, sheet-like adhesive, the basic structure is a three-dimensional structure that matches the ecology of cockroaches, and it can trap invading cockroaches by guiding them into the three-dimensional trap layer inside. Cockroaches that have invaded the inside of the three-dimensional structure cannot easily escape to the outside, and once trapped in the adhesive layer, they cannot escape even if they amputate their legs. In this way, the three-dimensional cockroach trap of the present invention has a three-dimensional structure that forms the core of the trap and a three-dimensional trap layer located inside it, resulting in a cockroach trap with an unprecedented three-dimensional structure. Furthermore, the three-dimensional trap layer has a significantly increased adhesive surface area compared to conventional cockroach traps. Conventional cockroach traps have only a single layer of adhesive surface, so the adhesive surface area is limited to the area of ​​the adhesive surface. On the other hand, the three-dimensional trap layer of the present invention has a three-dimensional continuous structure, so the adhesive surface area is significantly increased in three dimensions.

[0014] In the above configuration, the three-dimensional structure may further include a three-dimensional guide passage section extending from the outer surface toward the inside and having a guide passageway with a hole structure having a diameter that allows the adult cockroaches to pass through, through which the adult cockroaches are guided and enter. With the above configuration, by providing a three-dimensional guide passage section, the hole diameter of the three-dimensional structure that forms the basic structure can be made relatively small, improving structural strength, and the three-dimensional guide passage section becomes a hole or gap that adult cockroaches prefer, so that adult cockroaches that enter the interior through the three-dimensional guide passage section can be efficiently captured by the three-dimensional trap layer.

[0015] Next, in the above configuration, the three-dimensional structure has a diameter that adult cockroaches cannot pass through, does not contain adhesive inside, and has multiple three-dimensional guide passages intermittently formed from its outer surface toward the inside, and it is preferable that a three-dimensional trap layer is provided at the end of the guide passage of the three-dimensional guide passage. In other words, the adhesive layer is not exposed on the outer surface of the three-dimensional structure, and cockroaches enter the interior of the three-dimensional structure from the outer surface, but it is preferable to allow them to enter the interior of the three-dimensional structure until they reach the three-dimensional trap layer, where they are captured by the adhesive and are unable to move. With the above configuration, adult cockroaches arriving from the guide passage reach the three-dimensional trap layer and come into contact with the adhesive.

[0016] The material from which the three-dimensional structure, open mesh, open cell or open lattice body can be formed is not particularly limited, but can be, for example, polyurethane resin, other resins, sponge, rubber, polystyrene foam, etc. The basic structure of a three-dimensional structure can be obtained by forming it, for example, by foaming polyurethane resin, and it can then be freely cut to any size or shape.Even the cut pieces will have each component, such as a three-dimensional structure, a three-dimensional induction passage section, and a three-dimensional trap layer, so the installation location is not limited, and the size can be freely adjusted to install it in gaps in walls, gaps in furniture, inside a closet, etc.

[0017] As a measure to be taken here, it is preferable that the three-dimensional guide passage section is angled so that its diameter decreases as it moves from the surface of the three-dimensional structure toward the interior.Furthermore, it is preferable that the inner wall surface of the three-dimensional guide passage section has an exposed three-dimensional continuous mesh, open-cell, or open-lattice structure, which is a three-dimensional continuous structure with a diameter that allows the legs of an adult cockroach to fit into. With the above-mentioned measures, the structure is such that adult cockroaches can only move forward, and even if they try to move backward, they are not large enough to turn their bodies around. Even if they try to "back up," the legs of the adult cockroaches get caught in the mesh or lattice of the three-dimensional structure on the wall, making it impossible for them to "back up."

[0018] Furthermore, as a further innovation, in order to ensure capture in the three-dimensional trap layer, it is preferable that the "passage facing area" of the three-dimensional trap layer facing the guide passage of the three-dimensional guide passage section has a hole size that is large enough for the head of an adult cockroach to enter but not for the thorax or abdomen to enter, so that the body of the cockroach can fit inside. This device ensures that the body, legs, or wings of adult cockroaches are captured reliably by the adhesive impregnated in the area facing the passage.

[0019] On the other hand, the three-dimensional cockroach trap of the present invention captures not only adult cockroaches but also larval cockroaches. For example, the "non-pathway facing area" of the three-dimensional trap layer, other than the area facing the guide path of the three-dimensional guide passage section, preferably has small pores that allow larval cockroaches to enter by slipping into the gaps. With this innovation, larval cockroaches that reach directly from the outer surface of the three-dimensional structure are captured by the adhesive in the non-pathway facing area. In other words, it is preferable that the three-dimensional trap layer is not exposed on the outer surface of the three-dimensional structure, and that the cockroach penetrates into the three-dimensional trap layer until part of its body is caught by the adhesive of the three-dimensional trap layer and it is unable to move, so that its legs, back, body and wings are caught by the adhesive thread-like walls and pillars within the three-dimensional mesh structure, and it is no longer able to move by its legs, making it impossible for it to escape.

[0020] As an example, the pore diameter of the three-dimensional continuous mesh structure may be 1 to 5 mm, the diameter of the guide passage of the three-dimensional guide passage portion may be 5 to 20 mm, the diameter of the passage-facing area of ​​the three-dimensional trap layer may be 5 to 8 mm, and the diameter of the non-passage-facing area of ​​the three-dimensional trap layer may be 1 to 5 mm. At these sizes, the diameter of the three-dimensional continuous mesh structure is too small for adult cockroaches to enter, but they can find the three-dimensional guide passage and enter inside.In addition, the diameter of the area opposite the passage at the entry point is large enough that adult cockroaches can enter headfirst, but cannot pass through with their entire body, so they can effectively capture adult cockroaches. Furthermore, if the pore size of the three-dimensional continuous mesh structure, which is the basic structure, is made large enough that adult cockroaches can easily pass through, it may not be an environment that is suitable for adult cockroaches, who prefer gaps, and the structural strength of the three-dimensional cockroach trap of the present invention will be reduced.

[0021] The adhesive impregnated into the three-dimensional trap layer is not limited, but for example, an acrylic adhesive containing an acrylic acid ester copolymer is suitable. It is also preferable that the three-dimensional trap layer contains an attractant bait, such as a cockroach carcass or p-anisaldehyde, or a combination thereof. The three-dimensional cockroach trap of the present invention can be installed by simply placing it on the ground, or by attaching it to the installation location. In this case, if one side of the three-dimensional structure is coated with an adhesive or the above-mentioned pressure-sensitive adhesive, it can be attached to the installation location by pasting it from that side.

[0023] Examples of the test piece processing machine of the present invention will be described below. However, the present invention is not limited to these examples. It goes without saying that the scope of the present invention is not limited to the specific uses, shapes, numbers, etc. shown in the following examples. Example 1

[0024] Hereinafter, the first embodiment will be described with reference to FIGS. Then, a second embodiment will be described with reference to FIGS. 1, 5 and 6. FIG. After that, a third embodiment will be described with reference to FIGS. 1, 7 and 8. FIG. First, a configuration example of a three-dimensional cockroach trap according to a first embodiment of the present invention will be described. FIG. 1 is a simplified diagram illustrating the structure of a three-dimensional cockroach trap 100 of the present invention. 1 is a perspective view of a three-dimensional cockroach trap 100 according to the present invention, which is shown in a simplified form for ease of understanding. As shown in Figure 1, the three-dimensional cockroach trap 100 of the present invention is configured to include three-dimensional structures 110a and 110b, a three-dimensional trap layer 130 sandwiched between the three-dimensional structures 110a and 110b, and a three-dimensional guide passage 120 that serves as a passage leading from the outer surfaces of the three-dimensional structures 110a and 110b to the internal three-dimensional trap layer 130. 2(a) is a six-view diagram of the three-dimensional cockroach trap 100 according to Example 1. FIG. 2(b) is an enlarged view of the vertical cross section of the three-dimensional guide passage section 120. In Figure 2(a), only three of the six views are shown: a front view, a right side view, and a plan view. The back view is the same as the front view and is therefore not shown, the left side view is the same as the right side view and is therefore not shown, and the bottom view is the same as the plan view and is therefore not shown.

[0025] Each component will be described below in order. The three-dimensional structure 110 is a structure with holes large enough for cockroaches to pass through, and in this example configuration, it is located on the front and back of the three-dimensional trap layer 130, providing the basic structure of the entire three-dimensional cockroach trap 100 and also serves to prevent the three-dimensional trap layer 130 from being exposed. In this example, a porous body with a continuous structure of an open mesh, open cell, or open lattice is used as the three-dimensional structure 110. For example, the pore size of the continuous structure is preferably 1 to 5 mm. In Japan, the main cockroaches are the Smoky brown cockroach, the Japanese cockroach, the American cockroach, and the German cockroach. Adult German cockroaches are said to have a body length of about 15-18 mm, adult Smoky brown cockroaches and adult Japanese cockroaches are about 25-30 mm, and adult American cockroaches are about 30-40 mm. Cockroaches are long vertically, so their width is relatively narrow compared to their body length. For the three-dimensional structure 110 that forms the basic structure, a hole diameter of 1-5 mm is appropriate to prevent these adult cockroaches from passing through. Possible materials for the porous body include polyurethane resin (soft polyurethane foam, hard polyurethane foam, elastomer, etc.), other resins (polyethylene, melamine, EVA, etc.), sponge, rubber, polystyrene foam, or a combination of these. Other materials can also be used as long as they can be used to create a moderately open-mesh, open-cell, or open-lattice porous body.

[0026] The three-dimensional guide passage 120 is a guide passage extending from the surface of the three-dimensional structure 110 toward the three-dimensional trap layer 130 inside, and is a guide passage through which adult cockroaches are guided and enter, with a hole structure having a diameter that allows adult cockroaches to pass through. Although the number is not limited, in this example, a plurality of the holes are formed intermittently from the outer surface of the three-dimensional structure 110 toward the inside.

[0027] FIG. 2(b) is an enlarged view of a portion of the vertical cross section of the three-dimensional guide passage section 120 of the three-dimensional cockroach trap 100. As shown in FIG. 2(b), the shape of the three-dimensional guiding passage section 120 according to the first embodiment is a cylindrical type. That is, the diameter of the three-dimensional guiding passage section 120 does not change according to the depth, and the inner wall surface is a vertical surface. The opening shape of the three-dimensional guiding passage section 120 can be various, such as a substantially circular shape, a substantially elliptical shape, a substantially rectangular shape, a curved shape, etc. In the example of Fig. 1, the opening is a substantially rectangular shape.

[0028] The hole diameter of the three-dimensional guide passage section 120 is large enough for adult cockroaches to pass through, making it easy for them to be guided and enter. For example, the diameter of the guide passage of the three-dimensional guide passage section 120 is appropriately 5 to 20 mm, which is a size that matches the width (passage width) of an adult cockroach. Cockroaches prefer somewhat narrow passages, and as will be described later, the size of the passage should be such that adult cockroaches cannot change direction once they reach the three-dimensional trap layer 130. The inner wall surface of the three-dimensional guide passage section 120 also has an exposed three-dimensional structure similar to the three-dimensional structure 110, and the inner wall surface is also a continuous mesh, open-cell, or open-lattice structure with pore diameters of approximately 1 to 5 mm.

[0029] The three-dimensional trap layer 130 contains an adhesive for capturing cockroaches inside, has a diameter that prevents adult cockroaches from passing through, and is a central component that captures adult cockroaches that arrive through the guide passage of the three-dimensional guide passage section 120 with the adhesive. The three-dimensional trap layer 130 is sandwiched between the three-dimensional structures 110a and 110b. That is, as shown in Figure 1, the three-dimensional trap layer 130 for capturing cockroaches is located inside the three-dimensional structure 110 and not exposed on the outer surface. The height of the three-dimensional trap layer 130 is not particularly limited, as long as it is a height suitable for capturing adult cockroaches.

[0030] The three-dimensional trapping layer 130 has two areas: a passage-facing area 131 and a non-passage-facing area 132. The three-dimensional trap layer 130 has a passage-facing area 131 at a location facing the guide passage of the three-dimensional guide passage section 120, and a non-passage-facing area 132 is provided at a location other than the three-dimensional trap layer 130 facing the guide passage of the three-dimensional guide passage section 120. The passage-facing area 131 is a trap area for capturing adult cockroaches guided by the three-dimensional guide passage section 120, and the diameter of the hole is preferably set to a size that allows the head of an adult cockroach to enter but not the thorax or abdomen, so that the entire body of the adult cockroach can fit in. The adhesive impregnated in the passage-facing area 131 ensures that the body, legs, or wings of the adult cockroach are captured reliably. On the other hand, the non-passage-facing area 132 is an area designed to capture small cockroach larvae that may enter directly from the three-dimensional structure 110, and it is preferable that the holes have a small diameter that allows the larvae to enter by slipping into the gaps. In other words, the larvae that reach the three-dimensional structure 110 directly from the outer surface are captured by the adhesive in the non-passage-facing area 132.

[0031] The positional relationship between the three-dimensional guide passage section 120 and the passage-facing area 131 of the three-dimensional trap layer 130 is such that the passage-facing area 131 is located at the end of the guide passage of the three-dimensional guide passage section 120, and adult cockroaches arriving from the guide passage will encounter the passage-facing area 131. When the cockroach larvae reach the non-passage facing area 132 directly from the outer surface of the three-dimensional structure 110, not from the three-dimensional guide passage portion 120, the cockroach larvae are captured by the adhesive in the non-passage facing area 132.

[0032] As for the respective pore diameters, for example, the pore diameter of the three-dimensional continuous mesh structure 110 is 1 to 5 mm, and the diameter of the guide passage of the three-dimensional guide passage section 120 is 5 to 20 mm. Furthermore, the diameter of the passage-facing areas 131 of the three-dimensional trap layer 130 can be 5 to 8 mm, and the diameter of the non-passage-facing areas 132 of the three-dimensional trap layer 130 can be 1 to 5 mm. If the passage-facing area 131 has a hole diameter of 5 to 8 mm, the head of an adult cockroach can enter, but the hole diameter is too small for the thorax or abdomen to fit through. The passage-facing area 131 is impregnated with an adhesive, which effectively traps the body, legs, or wings of adult cockroaches. If the non-passage-facing area 132 has a hole diameter of 1 to 5 mm, larval cockroaches can enter, but the non-passage-facing area 132 is impregnated with adhesive, which effectively captures the body, legs, or back of the larval cockroach. Many larval cockroaches have underdeveloped wings, and their backs, bodies, and legs are caught by the adhesive thread-like walls and pillars in the three-dimensional mesh structure, making it impossible for them to escape, and effectively capturing the larval cockroaches.

[0033] Next, the adhesive will be described. The type of adhesive may be any type, such as acrylic, styrene, rubber, silicone, rosin, or polyurethane, but for example, an acrylic adhesive containing an acrylic acid ester copolymer can be used. The acrylic acid ester copolymers include acrylic triblock copolymers and acrylic diblock copolymers. In the acrylic triblock copolymer, it is more preferable that at least one of the polymer blocks A, B, and C is composed of an acrylic acid alkyl ester unit and / or a methacrylic acid alkyl ester unit, and it is even more preferable that all of the polymer blocks A, B, and C are composed of an acrylic acid alkyl ester unit and / or a methacrylic acid alkyl ester unit. It is particularly preferable that the polymer block A is composed of an methacrylic acid alkyl ester, the polymer block B is composed of an alkyl alkyl ester, and the polymer block C is composed of an methacrylic acid alkyl ester or an acrylic acid alkyl ester. Particularly suitable examples of acrylic triblock copolymers include triblock copolymers of the formula ABA or ABC, such as polymethyl methacrylate-b-polyn-butyl acrylate-b-polymethyl methacrylate, polymethyl methacrylate-b-polyethyl acrylate-b-polymethyl methacrylate, polymethyl methacrylate-b-polyn-butyl acrylate-b-polymethyl acrylate, polymethyl methacrylate-b-polyn-butyl acrylate-b-polyethyl acrylate, polymethyl methacrylate-b-poly2-ethylhexyl acrylate-b-polymethyl methacrylate, and the like.

[0034] The acrylic pressure-sensitive adhesive may consist solely of the triblock copolymer described above, or may contain other components as appropriate. Components that may be blended into the acrylic pressure-sensitive adhesive include acrylic diblock copolymers, tackifiers, etc., from the viewpoints of having good compatibility with the triblock copolymer, improving uniformity, and obtaining a pressure-sensitive adhesive with superior heat resistance and weather resistance. The acrylic diblock copolymer is a diblock copolymer represented by the general formula XY (wherein X represents a polymer block mainly composed of methacrylic acid alkyl ester units having an alkyl group with 1 to 4 carbon atoms or an alkyl group having a cyclic structure, and Y represents a polymer block mainly composed of acrylate alkyl ester units having an alkyl group with 1 to 20 carbon atoms and / or methacrylic acid alkyl ester units having an alkyl group with 5 to 20 carbon atoms). Preferably, the polymer block X is mainly composed of methacrylic acid alkyl ester units having an alkyl group with 1 to 4 carbon atoms, and the polymer block Y is mainly composed of acrylate alkyl ester units having an alkyl group with 1 to 20 carbon atoms.

[0035] In the polymer block X, examples of the alkyl group having 1 to 4 carbon atoms include a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, a sec-butyl group, an isobutyl group, and a tert-butyl group. Examples of the alkyl group having a ring structure include a cyclopropyl group, a cyclobutyl group, a cyclopentyl group, a cyclohexyl group, a cycloheptyl group, and an isobornyl group. These groups may have a substituent, and examples of the substituent include alkoxy groups such as a methoxy group, an ethoxy group, an n-propoxy group, an isopropoxy group, and a tert-butoxy group; amino groups such as an N,N-dimethylamino group and an N,N-diethylamino group; and halogen atoms such as chlorine, bromine, and fluorine.

[0036] Examples of monomers constituting methacrylic acid alkyl ester units having an alkyl group having 1 to 4 carbon atoms or an alkyl group having a cyclic structure include methyl methacrylate, ethyl methacrylate, isopropyl methacrylate, sec-butyl methacrylate, isobutyl methacrylate, tert-butyl methacrylate, cyclohexyl methacrylate, isobornyl methacrylate, 2-methoxyethyl methacrylate, 2-(N,N-dimethylamino)ethyl methacrylate, trifluoromethyl methacrylate, etc. These can be used alone or in combination of two or more.

[0037] The polymer block represented by X in the general formula may contain only methacrylic acid alkyl ester units, but may also contain other monomer units other than methacrylic acid alkyl ester units having an alkyl group having 1 to 4 carbon atoms or an alkyl group having a ring structure, as long as the amount is small enough not to impair efficacy (usually 20% by mass or less relative to the total amount of polymer block X). Examples of such other monomer units include methacrylic acid alkyl esters having 5 or more carbon atoms, such as 2-ethylhexyl methacrylate and dodecyl methacrylate; acrylic acid alkyl esters, such as methyl acrylate, n-butyl acrylate and t-butyl acrylate; methacrylic acid esters other than alkyl esters, such as trimethylsilyl methacrylate; acrylic acid esters other than alkyl esters, such as trimethylsilyl acrylate; Examples of components derived from monomers include methacrylamides such as methacrylamide, N-methylmethacrylamide, N-ethylmethacrylamide, N-isopropylmethacrylamide, N,N-dimethylmethacrylamide, and N,N-diethylmethacrylamide; acrylamides such as acrylamide, N-methylacrylamide, N-ethylacrylamide, N-isopropylacrylamide, N,N-dimethylacrylamide, and N,N-diethylacrylamide; vinyl monomers having a carboxyl group such as methacrylic acid, acrylic acid, crotonic acid, maleic acid, maleic anhydride, and fumaric acid; aromatic vinyl monomers such as styrene, α-methylstyrene, and p-methylstyrene; conjugated diene monomers such as butadiene and isoprene; olefins such as ethylene and propylene; and lactones such as ε-caprolactone and valerolactone.

[0038] In the polymer block Y, examples of the alkyl group having 1 to 20 carbon atoms include a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, an isobutyl group, a sec-butyl group, a tert-butyl group, a 2-methylbutyl group, a 3-methylbutyl group, an n-octyl group, a 2-ethylhexyl group, an isononyl group, a dodecyl group, a tridecyl group, and a stearyl group. Examples of the alkyl group having 5 to 20 carbon atoms include an n-pentyl group, a 2-methylbutyl group, a 3-methylbutyl group, an n-octyl group, a 2-ethylhexyl group, a dodecyl group, and a stearyl group. These groups may have a substituent, and examples of such a substituent include alkoxy groups such as a methoxy group, an ethoxy group, an n-propoxy group, an isopropoxy group, and a tert-butoxy group; amino groups such as an N,N-dimethylamino group and an N,N-diethylamino group; and halogen atoms such as chlorine, bromine, and fluorine.

[0039] Examples of monomers constituting acrylate alkyl ester units having an alkyl group having 1 to 20 carbon atoms include methyl acrylate, ethyl acrylate, n-propyl acrylate, isopropyl acrylate, n-butyl acrylate, isobutyl acrylate, sec-butyl acrylate, tert-butyl acrylate, n-hexyl acrylate, 2-ethylhexyl acrylate, dodecyl acrylate, tridecyl acrylate, stearyl acrylate, 2-methoxyethyl acrylate, 2-(N,N-dimethylamino)ethyl acrylate, trifluoromethyl acrylate, trimethoxysilylpropyl acrylate, etc. These can be used alone or in combination of two or more.

[0040] Examples of monomers constituting methacrylic acid alkyl ester units having an alkyl group having 5 to 20 carbon atoms include n-pentyl methacrylate, n-hexyl methacrylate, 2-ethylhexyl methacrylate, dodecyl methacrylate, tridecyl methacrylate, stearyl methacrylate, 2-methoxypentyl methacrylate, 2-(N,N-dimethylamino)pentyl methacrylate, perfluoropentyl methacrylate, 2-trimethoxysilylpentyl methacrylate, etc. These can also be used alone or in combination of two or more.

[0041] The polymer block represented by Y in the general formula may contain only alkyl acrylate units having an alkyl group with 1 to 20 carbon atoms and / or alkyl methacrylate units having an alkyl group with 5 to 20 carbon atoms, but may contain other monomer units other than alkyl acrylate units having an alkyl group with 1 to 20 carbon atoms and / or alkyl methacrylate units having an alkyl group with 5 to 20 carbon atoms in a small proportion (20% by mass or less based on the total amount of polymer block Y) within a range that does not impair efficacy. Examples of such monomer units include alkyl acrylates having an alkyl group with 21 or more carbon atoms, alkyl methacrylates having an alkyl group with 1 to 4 carbon atoms, alkyl methacrylates having an alkyl group with 21 or more carbon atoms, methacrylic acid esters other than alkyl esters such as trimethylsilyl methacrylate, acrylic acid esters other than alkyl esters such as trimethylsilyl acrylate, methacrylamide, N-methylmethacrylamide, N-ethylmethacrylamide, N-isopropylmethacrylamide, N,N-dimethylmethacrylamide, and N,N-diethylmethacrylamide. Examples of suitable monomers include acrylamides, acrylamide, N-methylacrylamide, N-ethylacrylamide, N-isopropylacrylamide, N,N-dimethylacrylamide, and N,N-diethylacrylamide; vinyl monomers having a carboxyl group, such as methacrylic acid, acrylic acid, crotonic acid, maleic acid, maleic anhydride, and fumaric acid; aromatic vinyl monomers, such as styrene, α-methylstyrene, and p-methylstyrene; conjugated diene monomers, such as butadiene and isoprene; olefins, such as ethylene and propylene; and lactones, such as ε-caprolactone and valerolactone.

[0042] The diblock copolymer represented by the above general formula 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. Furthermore, in order to improve and easily adjust tack, adhesive strength, and holding power, 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, maleated rosin, and disproportionated rosin ester; terpene-phenolic resins; terpene-based resins mainly composed of α-pinene, β-pinene, and limonene; (hydrogenated) petroleum resins; coumarone-indene-based resins; hydrogenated aromatic copolymers; styrene-based resins; phenol-based resins; and xylene-based resins. These can be used alone or in combination of two or more. The presence or absence of the diblock copolymer, triblock copolymer, and tackifier and the blending ratio can be appropriately selected depending on the use of the adhesive product, the type of adherend, etc., and are not particularly limited. The pressure-sensitive adhesive may be an emulsion type pressure-sensitive adhesive or a hot-melt type pressure-sensitive adhesive.

[0043] Such adhesive 12 is impregnated into the material of the three-dimensional structures 110a and 110b. If the amount of impregnation is too small, the effect is small, but if the amount is too large, the adhesive will crush the mesh of the three-dimensional structures 110a and 110b, making it impossible to maintain the three-dimensional mesh structure. Therefore, the impregnation amount is set to a level that will spread over the walls and columns of the three-dimensional mesh structure, such as polyurethane, but will not fill the gaps between the squares. For example, the impregnation amount is set to a range of 10 to 200 g / m², and one example is 100 g / m².

[0044] The adhesive's viscosity needs to remain within the three-dimensional mesh structure of polyurethane or the like, so if it is too low there is a risk that it will flow out, but if it is too high it will be difficult to apply and the adhesive layer will not spread evenly over the entire three-dimensional trapping layer 130. Therefore, the viscosity should be such that it does not easily flow out of the three-dimensional mesh structure and is suitable for application.

[0045] The adhesive may be applied by any application method, but for example, the adhesive may be applied using a printing technique similar to silk screen printing. In other words, the adhesive is treated as silk screen ink and is uniformly applied to the surfaces of the three-dimensional structures 110a and 110b in a manner similar to printing. In this case, the method for manufacturing three-dimensional trapping layer 130 involves pressing three-dimensional structures 110a and 110b, each having an adhesive printed on its surface, together to bond them together, thereby producing three-dimensional trapping layer 130. As an application method, instead of silk screen printing, a method of continuously applying the paint to the roll-shaped three-dimensional structures 110a and 110b using a roller is also possible. The adhesive surface area of ​​the three-dimensional trap layer 130 is dramatically increased compared to conventional cockroach traps. In this example, the three-dimensional trap layer 130 is a three-dimensional structure, a three-dimensional mesh structure or a three-dimensional lattice structure, and the skeletal structure is impregnated with an adhesive, so the area is dramatically increased in three dimensions.

[0046] The three-dimensional trap layer 130 contains bait to attract cockroaches. For example, the bait may contain either a dead cockroach or p-anisaldehyde, or a combination of both. The dead cockroach is a bait that takes advantage of the cannibalistic nature of cockroaches. Since the three-dimensional trap layer 130 contains the bait, the cockroaches are attracted towards the three-dimensional trap layer 130.

[0047] The above is a description of the configuration of each part of the three-dimensional cockroach trap 100 of the present invention.

[0048] The three-dimensional cockroach trap 100 of the present invention can be installed anywhere where cockroaches are expected to live and pass through, such as gaps in walls, gaps in furniture, around refrigerators, in the kitchen, on sofas, cushions, and in closets. By applying adhesive to the three-dimensional structure 110a or 110b on the front or back of the three-dimensional cockroach trap 100 of the present invention, the installation location and installation posture can be freely determined. However, it can also be simply placed without adhesive. Furthermore, since the adhesive is located in the three-dimensional trap layer 130 inside the three-dimensional structure 110, it can be installed near a wet area.

[0049] 3A to 3C are diagrams illustrating the process of capturing cockroaches using the three-dimensional cockroach trap 100 of the present invention according to Example 1. Cockroaches are captured as shown in Fig. 3A to Fig. 3C. Cockroaches live in large numbers in the installation area and are constantly moving around. Since the three-dimensional trap layer 130 contains the bait, the cockroaches are attracted towards the three-dimensional trap layer 130.

[0050] Cockroaches first attach themselves to the surface of the three-dimensional structure 110a on the front side of the three-dimensional cockroach trap 100 or the surface of the three-dimensional structure 110b on the back side, and then enter the interior. Adult cockroaches enter the interior through the three-dimensional guide passage 120. Eventually, as shown in FIG. 3(a), the adult cockroach enters through the three-dimensional guide passage 120, passes through the three-dimensional structure 110a or 110b, and reaches the three-dimensional trap layer .

[0051] Eventually, as shown in FIG. 3(b), the adult cockroach reaches the three-dimensional trap layer 130 and comes across the passage-facing area 131 of the three-dimensional trap layer 130.

[0052] The passage-facing area 131 is impregnated with adhesive, and its diameter is small enough that the thorax and abdomen cannot pass through. As shown in Figure 3(c), as the cockroach reaches the three-dimensional trap layer 130 and moves around, parts of the cockroach other than the legs, such as the thorax, abdomen, and wings, come into contact with the adhesive-impregnated three-dimensional structure, and the parts of the cockroach other than the legs are trapped and cannot move.

[0053] Conventional cockroach traps are flat and only capture the legs of a cockroach, which only captures a small part of the cockroach's body, eventually causing the cockroach to break away and escape. However, the three-dimensional cockroach trap 100 of the present invention has a structure impregnated with adhesive in all three dimensions, so that it can capture cockroaches from all directions when they invade the three-dimensional trap layer 130. In particular, when the cockroach's thorax, abdomen, or wings are captured by the adhesive, the adhesive surface area is large, and the inner wall surface is an exposed three-dimensional structure of a continuous mesh, open-cell, or open-lattice structure, meaning that the legs cannot be stretched out. Once a cockroach is trapped by the adhesive, there is no way for it to escape, and it remains trapped until it is completely dead. When the back or body of the cockroach gets stuck on the three-dimensional trap layer 130, the legs get stuck in the three-dimensional structure, and the cockroach is in a situation where it cannot escape even if it thrashes its legs.

[0054] Next, we will discuss capturing larval cockroaches. The three-dimensional cockroach trap 100 of the present invention mainly captures adult cockroaches in the passage-facing area 131, but mainly captures larvae cockroaches in the non-passage-facing area 132. FIG. 4 is a simplified diagram showing how the three-dimensional cockroach trap 100 of the present invention traps larval cockroaches. As shown in Figure 4(a), the three-dimensional structures 110a and 110b located on the outer surface have holes of a size that adult cockroaches cannot enter directly, but larval cockroaches can. Beyond these holes is a non-passage-facing area 132, the diameter of which is kept small so that the legs, torso, wings, etc. of larval cockroaches come into contact with the adhesive impregnated in the non-passage-facing area 132 and are trapped. The non-passage-facing area 132 is also impregnated with adhesive, so the larval cockroaches are trapped.

[0055] As shown in Figure 4(b), if the non-passage-facing area 132 has a hole diameter of 1 to 5 mm, larval cockroaches can enter, but the non-passage-facing area 132 is impregnated with adhesive, which effectively captures the body, legs, or back of the larval cockroach. Many larval cockroaches have underdeveloped wings, and their backs, bodies, or legs are caught by the adhesive thread-like walls and pillars in the three-dimensional mesh structure, making it impossible for them to escape, and effectively capturing the larval cockroaches. The above is an explanation of the process of catching cockroaches using the three-dimensional cockroach trap 100 of the present invention.

[0056] In the above description, the three-dimensional structures 110a and 110b and the three-dimensional trapping layer 130 are described as having a porous body with a continuous structure, but the same applies to a mesh-like continuous lattice structure. A mesh-like continuous lattice structure has a more regular three-dimensional structure than a continuous porous body, but by adjusting the mesh size and creating a three-dimensional structure with a mesh diameter of 1 to 5 mm, three-dimensional structures 110a and 110b are obtained. Example 2

[0057] Second Embodiment A three-dimensional cockroach trap 100A according to a second embodiment of the present invention will be described. The three-dimensional cockroach trap 100A according to the second embodiment has the same configuration as that of the first embodiment, ie, the configuration shown in FIG. In other words, the three-dimensional cockroach trap 100A of Example 2 is configured to include three-dimensional structures 110Aa and 110Ab, a three-dimensional trap layer 130A sandwiched between the three-dimensional structures 110Aa and 110Ab, and a three-dimensional guide passage 120A that serves as a passage leading from the outer surfaces of the three-dimensional structures 110Aa and 110Ab to the internal three-dimensional trap layer 130A.

[0058] Fig. 5(a) is a six-view diagram of a three-dimensional cockroach trap 100A according to Example 2. Fig. 5(b) is an enlarged view of a vertical cross section of a three-dimensional guide passage section 120A. In Figure 5(a), only three of the six views, the front view, right side view, and plan view, are shown, but the back view is the same as the front view and is not shown, the left side view is the same as the right side view and is not shown, and the bottom view is the same as the plan view and is not shown.

[0059] Each component will be described below in order. The three-dimensional structure 110A is the same as in Example 1, and therefore a description thereof will be omitted here. A three-dimensional structure 110Aa on the front side and a three-dimensional structure 110Ab on the back side are provided.

[0060] 5(b), the three-dimensional guide passage section 120A according to the second embodiment has a so-called tapered shape, that is, an inclined angle is provided on the inner wall surface so that the diameter becomes smaller from the surface of the three-dimensional structure 110A toward the inside.

[0061] If the three-dimensional guidance passage section 120A has such a structure, the movement margin becomes smaller as the adult cockroach moves forward, and it is configured so that it can only move forward. Even if the adult cockroach tries to move backward, it is not large enough to turn its body around. Even if the adult cockroach tries to "back up", its legs get caught in the mesh or lattice of the three-dimensional structure on the wall and it is not able to "back up".

[0062] Similar to the first embodiment, the three-dimensional trapping layer 130A has two areas: a passage-facing area 131A and a non-passage-facing area 132A. As shown in Figure 5(b), a passage-facing area 131A is provided in the three-dimensional trap layer 130A at a location facing the guide passage of the three-dimensional guide passage section 120A, and a non-passage-facing area 132A is provided in the three-dimensional trap layer 130A other than a location facing the guide passage of the three-dimensional guide passage section 120A. The passage-facing area 131A is a trap area for capturing adult cockroaches guided by the three-dimensional guide passage section 120A, as in the first embodiment, and the diameter of the hole is preferably set to a size that allows the head of an adult cockroach to enter but not the thorax or abdomen, so that the entire body of the adult cockroach can fit in. The adhesive impregnated in the passage-facing area 131A ensures that the body, legs, or wings of the adult cockroach are captured reliably. On the other hand, the non-passage-facing area 132A is an area designed to capture small cockroach larvae that would otherwise enter directly from the three-dimensional structure 110A, as in Example 1, and preferably has small openings that allow larval cockroaches to enter by slipping into the gaps. In other words, larval cockroaches that reach the three-dimensional structure 110A directly from the outer surface thereof are captured by the adhesive in the non-passage-facing area 132A.

[0063] Regarding the positional relationship between the three-dimensional guide passage section 120A and the passage-facing area 131A of the three-dimensional trap layer 130A, the guide passage of the three-dimensional guide passage section 120A is tapered, and beyond that is the passage-facing area 131A, and adult cockroaches that arrive from the guide passage are led directly to the passage-facing area 131A. When the cockroach larvae reach the non-passage facing area 132A directly from the outer surface of the three-dimensional structure 110A, rather than from the three-dimensional guide passage portion 120A, the cockroach larvae are captured by the adhesive in the non-passage facing area 132A.

[0064] Figure 6 is a diagram illustrating the process of capturing cockroaches using the three-dimensional cockroach trap 100A according to the second embodiment shown in Figure 5. Cockroaches are captured as shown in Figure 6(a) to Figure 6(c). Cockroaches live in large numbers in the installation area and are constantly moving around. Since the three-dimensional trap layer 130A contains the bait, the cockroaches are attracted toward the three-dimensional trap layer 130A.

[0065] Cockroaches first attach themselves to the surface of the three-dimensional structure 110a on the front side of the three-dimensional cockroach trap 100A or the surface of the three-dimensional structure 110Ab on the back side, and then enter the interior. Adult cockroaches enter the interior through the three-dimensional guide passage portion 120A. 6(a), the adult cockroach enters through the three-dimensional guide passage 120A, passes through the three-dimensional structure 110Aa or 110Ab, and reaches the three-dimensional trap layer 130A. The three-dimensional guide passage 120A becomes narrower as it enters, allowing the adult cockroach to enter forward but making it difficult for it to turn around.

[0066] Eventually, as shown in FIG. 6(b), the adult cockroach reaches the three-dimensional trapping layer 130A and comes across the passage-facing area 131A of the three-dimensional trapping layer 130A. The passage-facing area 131A is impregnated with an adhesive, and its diameter is small enough that the thorax and abdomen cannot pass through. As shown in Figure 6(c), when a cockroach reaches the three-dimensional trap layer 130A and moves around, parts of the cockroach other than the legs, such as the thorax, abdomen, and wings, come into contact with the adhesive-impregnated three-dimensional structure, and the parts of the cockroach other than the legs are trapped and cannot move. Example 3

[0067] A configuration example of a three-dimensional cockroach trap 100B according to a third embodiment of the present invention will be described. Explanation of the same parts as in the first embodiment will be omitted. The three-dimensional cockroach trap 100B of Example 3 has a similar configuration, including three-dimensional structures 110Ba and 110Bb, a three-dimensional trap layer 130B sandwiched between three-dimensional structures 110a and 110b, and a three-dimensional guide passage 120B that serves as a passage leading from the outer surfaces of three-dimensional structures 110a and 110b to the internal three-dimensional trap layer 130B.

[0068] The three-dimensional cockroach trap 100B according to the third embodiment has a different shape for the passage-facing area 131B of the three-dimensional trap layer 130B. FIG. 7 is a simplified diagram illustrating the structure of the passage-facing area 131B of the three-dimensional cockroach trap 100B according to the third embodiment. As shown in Figure 7, the passage-facing area 131B has an inner wall that is tapered toward the front, and is provided with a so-called "return." This "return" is one of the innovations. Needless to say, a configuration without the "return" is also possible.

[0069] The narrowest gap in the passage-facing area 131B is, for example, about 5 mm, a size that prevents adult cockroaches from passing through. The shape of the narrowest gap is not particularly limited, and various shapes are possible, such as a roughly cylindrical or roughly rectangular shape. In this example, the opening is a roughly cylindrical hole. The smallest opening in the passage-facing area 131B is sized so that the head of an adult cockroach can enter but the thorax or abdomen cannot, and the entire body of the adult cockroach can fit in. The adhesive impregnated in the passage-facing area 131B ensures that the body, legs, or wings of the adult cockroach are captured. 8A to 8C are diagrams illustrating the process of capturing cockroaches using the three-dimensional cockroach trap 100B according to Example 2. Cockroaches are captured as shown in Fig. 8A to Fig. 8C.

[0070] Adult cockroaches enter the interior through the three-dimensional guide passage portion 120B. Eventually, as shown in FIG. 8(a), the adult cockroach enters through the three-dimensional guide passage portion 120B, passes through the three-dimensional structure 110Ba or 110Bb, and reaches the three-dimensional trapping layer 130B.

[0071] Eventually, as shown in FIG. 8(b), the adult cockroach reaches the three-dimensional trapping layer 130B and comes across the passage-facing area 131B of the three-dimensional trapping layer 130B. The three-dimensional guide passage section 120B of the third embodiment is also an example having a tapered shape that becomes narrower as it advances, allowing adult cockroaches to advance forward but making it difficult for them to turn around. The narrowest gap in the area opposite the passageway, 131B, is so small that an adult cockroach can stick its head through but not its thorax or abdomen, and because it has barbs, it is no longer able to move.

[0072] The passage-facing area 131B is impregnated with an adhesive, and the smallest gap in the passage-facing area 131B is so small that the thorax or abdomen cannot pass through. As shown in Figure 8(c), the adult cockroach's body gets stuck, and parts of the cockroach other than the legs, such as the thorax, abdomen, and wings, come into contact with the adhesive-impregnated three-dimensional structure, trapping the parts other than the legs and preventing them from moving.

[0073] While the preferred embodiment of the three-dimensional cockroach trap of the present invention has been shown and described above, it will be understood that various modifications can be made without departing from the spirit and scope of the invention. [Industrial Applicability]

[0074] The three-dimensional cockroach trap of the present invention can be used as a trap for capturing cockroaches. It can be installed in a wide range of locations where cockroaches live, such as gaps in walls, gaps in furniture, around refrigerators, in kitchens, on sofas, on cushions, and in closets, and can be installed in any position.
