Description

  TECHNICAL FIELD The present invention relates to an adhesive trap for trapping insects, and more particularly, to an adhesive trap suitable for capturing minute-walking insects such as chatters and mites.

  The cell culture process and the pharmaceutical manufacturing process are areas that require a high degree of cleanliness that dislike foreign substances and have limited nutrient sources for arthropods. It is almost limited to debris on the body surface and micro-walking insects such as chatters and mites that eat filamentous fungi.

  Currently, almost all high cleanliness areas use gamma-sterilized cockroach sticky traps for monitoring to verify and demonstrate the absence of arthropods. For monitoring of micro-walking insects, insect trapping sheets provided with an adhesive layer on a base material (Patent Document 1) or insect trapping sheets provided with an adhesive layer in a predetermined shape on a non-adhesive sheet are used ( Patent Document 2). Further, as a pest-adhesive capturing sheet, there has been proposed a sheet in which an adhesive layer is present in a large number of cavities provided on a base sheet, and the pests are penetrated into the cavities by their infiltration behavior and are captured by the adhesive layer ( Patent Document 3).

  However, the insect trap sheet disclosed in Patent Literature 1 for catching micro-walking insects is long and has a problem that it is difficult to monitor the ceiling and the side of the room, the inside and the side of the manufacturing equipment, and the like. is there. Further, in the case of insect trapping sheets and insect pest sticking catching sheets as disclosed in Patent Documents 2 and 3, it is necessary that minute walking insects such as chatter bugs and ticks crawl on the non-sticking sheet and the base sheet. Therefore, there is a problem that the effect of capturing microwalking insects is low.

  In addition, it has been practiced that the adhesive layer contains microbial powders that are preferred by the micro-walking insects to be captured, or contains water retention components, thereby attracting the micro-walking insects and improving the capturing effect. . However, in a highly clean area such as a bio-clean room for pharmaceutical manufacturing, where gamma-ray sterilization is required for insect trap sheets for monitoring, attractants such as water and chemicals including natural substances cannot be used, which is an effective means. Does not.

  The present invention has been made in view of such circumstances, and has been used for capturing and monitoring microwalking insects on the sides, heavens, and inside of various facilities installed in a highly clean area. An object of the present invention is to provide an insect trap which can be used and has a high trapping effect.

  The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, in the case of a small walking insect such as chatters and mites to be captured in the present invention, the trap surface in the adhesive trap, the floor, the wall surface, etc. A trapezoidal area formed on the trap surface between the trap placement surface and the trapping surface forms a micro-height entry / capture area. The present inventors have found that the trapping efficiency is improved, so that the present invention has been completed.

  That is, the invention according to claim 1 for solving the above-mentioned problem is directed to an insect which is used by arranging one side of a base material with a sticky trap surface and arranging the trap surface facing a trap arrangement surface. An adhesive trap for trapping, wherein the trapping surface has a gap between the trapping surface and the trapping surface as an insect entry / capturing region, and has a fixing protrusion for adhering to the trapping surface. This is an adhesive trap for trapping insects.

  In one embodiment, the trap surface has an adhesive property with respect to the trap placement surface such that the fixing trap can be bonded, peeled, and re-bonded with the adhesive trap. In addition, the trap surface is an inclined surface such that the distance between the trap surface and the trap arrangement surface becomes narrower as the distance from the peripheral portion of the base material to the center portion or the depth increases.

  In one embodiment, the shape of the fixing convex portion when the trap surface is viewed in plan includes a cross-shaped shape in which a planar end extends to an edge of the base material, and The projection for use is formed by embossing the base material.

  In one embodiment, the fixing convex portion and the capturing convex portion are formed on the trap surface. Further, in one embodiment, a portion that is inclined from the fixing convex portion toward the trap surface is provided around a part or all of the fixing convex portion.

  Further, in one embodiment, the whole or a part of the surface of the base material is colored in a color effective for attracting insects, imparting light-shielding properties, or confirming captured insects. Further, a second adhesive layer may be provided on the whole or a part of the surface of the substrate opposite to the trap surface.

  The adhesive trap for trapping insects according to the present invention is used in such a manner that one surface of the substrate is a trap surface formed by adhesion, and the trap surface is disposed so as to face the trap arrangement surface. Since there is no need for micro-walking insects such as chatter beetles and mites, it is not necessary to crawl on the sticky surface, and it is possible to catch as long as it enters the gap between the trap surface and the trap arrangement surface, so the capture efficiency is greatly improved. In addition, it can be easily attached and placed on the side, top, inside, etc. of various facilities and equipment, and has an effect that it can be effectively used for monitoring and capturing of micro-walking insects.

  An embodiment for carrying out the present invention will be described with reference to the accompanying drawings. The drawings are schematic or conceptual, and the dimensions of each member, the ratio of the size between members, and the like do not necessarily reflect the actual product. Further, in the following description, expressions such as front and back, up and down, etc. are based on the state at the time of use.

  FIG. 1 is a rear view showing an embodiment of the insect trap according to the present invention. FIGS. 2 to 4 are taken along lines II, II-II and III-III in FIG. 1, respectively. FIG. As shown therein, the adhesive trap for trapping insects according to the present invention is arranged such that the back surface of the substrate 1 is the trap surface 2 having adhesiveness, and the trap surface 2 faces the trap arrangement surface 10. Is used.

  The trap surface 2 has a fixing convex portion 3 serving as a fixing portion by adhesion to a trap arrangement surface 10 such as a floor or a wall surface. The material of the base material 1 is not particularly limited as long as the shape of the fixing projections 3 can be maintained, and may be a material such as resin, nonwoven fabric, paper, metal, or a material appropriately combining them. . Above all, it is preferable to use a synthetic resin because the formation of the fixing projection 3 is easy. As the base material made of a synthetic resin, any of a stretched material and an unstretched material can be used. As the synthetic resin, for example, polyethylene, polypropylene, polyester, polystyrene, and polyurethane are preferable, and polyester such as stretched or unstretched polyethylene terephthalate, polystyrene, and polypropylene are particularly preferable. The substrate may be in any shape such as a sheet, a film, and a foil. The fixing projection 3 can be formed by pressing the base material 1 by embossing or the like (see FIGS. 1 to 7).

  Further, when it is necessary to perform gamma ray sterilization on the insect trap for trapping insects, it is desirable to select a substrate made of a material resistant to gamma ray sterilization. As the synthetic resin, polyester or polystyrene is preferably used.

  The trapping surface 2 can be formed by providing an adhesive layer 4 for capturing over the entire back surface of the substrate 1 or over substantially the entire surface. The entire surface of the fixing projection 3 is also covered with the adhesive layer 4 to serve as a trapping surface, and the tip end surface serves as a fixing surface by adhesion to the trap arrangement surface 10 such as a floor or a wall surface. It is needless to say that the adhesive layer 4 has an adhesive force for surely capturing the microwalking insects to be captured, but the adhesive force is such that the fixing projection 3 is bonded to the trap placement surface 10. It is preferable that the material be of such an extent that it can be peeled and re-laminated.

  The planar shape of the substrate 1 in the illustrated example is a rectangle, but is not limited thereto, and may be a polygonal shape, a circular shape, an oval shape, an elliptical shape, or any other shape. Can be arbitrarily set as long as the fixing projection 3 can be formed and maintained. The preferred thickness of the base material varies depending on the material. For example, in the case of using a synthetic resin sheet or film, the thickness of the base material is preferably 0. It is preferably from 02 to 0.8 mm, more preferably from 0.03 to 0.5 mm, and further preferably from 0.05 to 0.3 mm.

  Further, the shape (cross-sectional shape) of the fixing projection 3 in plan view may be arbitrary. In the example shown in FIG. 1, a large cross-shaped fixing projection 3 is formed such that the rectangular base material 1 is divided into four parts, and four fixing projections 3 divided by the cross-shaped fixing projection 3 are formed. A large number of long and short rod-shaped fixing projections 3 each having a rounded end are formed on each of the portions. As will be described later, the cross-shaped fixing convex portion 3 having a cross shape is effective in preventing the minute walking insect from passing through without being caught in the trap.

  The fixing protrusions 3 that define the distance between the trap surface 2 and the trap arrangement surface 10 may be formed such that all the fixing protrusions 3 are formed at substantially the same height in one adhesive trap, or are different. Although it can be formed so as to include one having a height or can be set as appropriate, in a preferred embodiment, the trap surface 2 is arranged such that the distance between the trap surface 2 and the trap arrangement surface 10 is larger than the peripheral portion of the base material 1. The central portion is formed so as to be narrower (see FIGS. 2, 4 and the like). Accordingly, the fixing projection 3 (3a) located at the peripheral edge of the base material 1 is formed so as to have a higher projecting height than the fixing projection 3 (3b) located at the center or the back side. (See FIG. 2).

  The fixing projections 3 (3a) located at the peripheral edge of the substrate 1 have a function of maintaining a gap between the peripheral edge of the substrate 1 and the trap placement surface 10 where small walking insects can enter. is there. Therefore, the height of the fixing projection 3 (3a) is set to be larger than the body height of the minute walking insect to be captured. For example, the height H when the main capture target is a caterpillar is set in a range of 1 to 5 mm. As a range of the height H, a range of 1 to 3 mm is preferable.

  On the other hand, the fixing projection 3 (3b) located at the center or the back side of the base material 1 narrows the gap between the trapping surface 2 and the trap placement surface 10 so that the back of the micro-walking insects that have entered can be trapped. It functions to generate a trappable space (capture space) that comes into contact with the surface 2. Therefore, the height of the fixing projection 3 (3b) is set to be smaller than the height of the micro walking insect to be captured. For example, the height h when the main capturing target is a caterpillar is set in the range of 0 to 2 mm. As a range of the height h, a range of 0.5 to 1.5 mm is preferable. Since the distance between the trapping surface 2 and the trap disposition surface 10 becomes narrower in the central portion or the back side of the substrate 1, the relationship between the height H and the height h is desirably h ≦ H.

  As shown in FIG. 2, the bottom surface of each fixing projection 3 before being arranged on the trap arrangement surface 10 is usually formed so as to be on the same plane. However, the trap placement surface 10 is not necessarily flat, and may have irregularities or a curved surface. Therefore, it is preferable that the substrate 1 has flexibility or flexibility. If the base material 1 has flexibility or flexibility, the fixing projections 3 are deformed along the surface shape of the trap placement surface 10 while the base material 1 is deformed along the surface shape of the trap placement surface 10. By pressing the trap in accordance with, the sticky trap for trapping insects can be stably arranged on the trap arrangement surface 10 (see FIG. 5).

  The adhesive trap for trapping insects according to the present invention is installed on the trap placement surface 10 such as a side surface, a top portion, or the inside of various facility facilities through the adhesive layer 4 on the bottom surface of the fixing projection 3. After the time elapses, the trapped small walking insect is peeled off from the trap placement surface 10 to verify the captured microwalking insect. Therefore, as described above, the adhesive layer 4 has an adhesive property that allows the fixing projection 3 to be bonded to and detached from the trap placement surface 10. Furthermore, if investigation is necessary continuously after confirmation of capture, it will be disposed again, so that it is preferable to have adhesiveness that allows re-bonding.

  The pressure-sensitive adhesive of the pressure-sensitive adhesive layer 4 can surely catch insects, and can sufficiently bond the trapping surface 2 and the trap disposition surface 10 in the fixing projection 3. The trap is not particularly limited as long as it can be peeled off and re-laminated, but adhesives conventionally used for insect catching sheets, for example, acrylic adhesives, urethane adhesives, silicone adhesives And any known adhesive such as a rubber-based adhesive. Further, when it is necessary to perform gamma ray sterilization on the insect trap for trapping insects, it is necessary to select an adhesive that is resistant to gamma ray sterilization. The thickness of the adhesive layer 4 can be appropriately set, for example, in the range of 1 to 1000 μm. The thickness of the adhesive layer 4 is preferably from 5 to 200 μm, more preferably from 10 to 80 μm.

  Next, an example of a method for manufacturing the adhesive trap for trapping insects according to the present invention having the above configuration will be described. The adhesive trap for trapping insects is provided, for example, by arranging an adhesive layer 4 on the back surface serving as the trapping surface 2 of the base material 1 in a flat state, and bonding a release film on the adhesive layer 4 to form a laminated film. The laminated film is manufactured by embossing with a press device to form a plurality of fixing projections 3.

  Alternatively, after a plurality of fixing projections 3 are formed on the flat base material 1 by embossing using a press device, the adhesive layer 4 is coated so as to cover the entire trapping surface 2 including the fixing projections 3. It is manufactured by forming and laminating a release film thereon. Note that the release film on the adhesive layer 4 is peeled off when the insect trap for trapping insects is used. Since the fixing projection 3 is hollow when manufactured by embossing, if necessary, a cover sheet is attached to the surface to flatten the surface. The substrate 1 may be solid (see FIG. 8).

  The insect trap for trapping insects having the above-mentioned configuration is used by being fixed to the trap arrangement surface 10 such as the side, top, or inside of various facility facilities via the adhesive layer 4 on the back surface of the fixing projection 3. The minute walking insect that has walked and moved on the trap placement surface 10 enters the trap from a gap between the peripheral portion of the trap surface 2 and the trap placement surface 10 where walking can enter. There are no steps climbing up, so microwalking insects can enter without any resistance.

  The micro-walking insects entering the trap move around freely, and eventually the antennae, the back surface, the legs and the like touch the top surface of the trap surface 2 and the adhesive layer 4 on the peripheral surface of the fixing projection 3 and are trapped by adhesion. When the trap surface 2 is inclined such that the distance between the trap surface 2 and the trap placement surface 10 is smaller at the center than at the periphery of the base material 1, the micro-walking insects move toward the back as the adhesive layer 4 It is easy to touch and sticky. If the fixing convex portion 3 has a cross shape such as a cross shape, the microwalking insects are blocked from going and cannot pass through, so that the trapping efficiency is improved.

  In addition, since the irradiation of light from the periphery to the inside is restricted by the base material 1 and the plurality of fixing projections 3, micro-walking insects having negative phototacticity are guided, and thus, extremely A high capture effect is achieved.

  The insect trap for trapping insects according to the present invention is not limited to the above-described embodiment, and various other embodiments can be considered. For example, in the example shown in FIG. 6, a plurality of capture protrusions 5 that do not reach the trap arrangement surface 10 are formed on the trap surface 2. When the trapping surface 2 is inclined downward toward the center, the capturing protrusions 5 may be the same (see FIG. 6A), but the capturing protrusions when the trapping surface 2 is horizontal. It is preferable that the portion 5 is formed larger as it is closer to the center, so that the distance between the portion 5 and the trap placement surface 10 is reduced (see FIG. 6B).

  In the example shown in FIG. 7, the trap surface 2 around the part or all of the fixing protrusions 3 is inclined downward toward the fixing protrusions 3 to form a gentle slope 2a. . In this case, as the distance between the trapping surface 2 and the trap placement surface 10 decreases as the distance from the fixing convex portion 3 decreases, the minute walking insect touches the adhesive surface as the distance approaches the fixing convex portion 3 and is easily captured.

  Further, the shape and arrangement of the fixing projection 3 in plan view are not limited to those shown in FIG. 1, but may be any other modes. 9 to 12 show examples in which a large number of fixing projections 3 having the same shape in plan view are arranged. The fixing projections 3 shown in FIG. 9 have a circular cross section and are arranged relatively densely. The fixing projection 3 shown in FIG. 10 has a round bar shape at both ends, the fixing projection 3 shown in FIG. 11 has an X-shape, and the fixing projection 3 shown in FIG. It has a triangular shape.

  In any of the above cases, not all of the projections need to be the fixing projections 3, and some of them may be the capture projections 5 that do not reach the trap placement surface 10. Then, a slope such as the gentle slope 2a in the embodiment shown in FIG. 7 may be formed on the trap surface 2 around the fixing projection 3. However, in this case, the slope is not a gentle slope but a steep slope because of space.

  In the case where the capturing projections 5 are mixed in the embodiment shown in FIGS. 9 to 12, the projection height of the capturing projections 5 does not need to be constant, and can be changed as appropriate. Generally, the distance between the bottom surface of the trapping projection 5 and the trap placement surface 10 is reduced so that the protrusion at the center portion is higher than that at the peripheral portion of the base material 1, in other words, at the center. (The directions of arrows CC ′ and DD ′ in FIG. 9). Alternatively, the projection height may be set so as to gradually increase from the near side to the deepest part (the direction of arrow A or B in FIG. 9).

  In any of the above embodiments, at the time of use, at the peripheral portion of the base material 1, the distance between the trapping surface 2 and the trap disposition surface 10 is set to be larger than the height of the microwalking insect to be captured. Therefore, the minute walking insect can walk and enter the trap, and since there is no step in the entry portion, the minute walking insect walks and enters the trap without any resistance. Then, as the micro-walking insects enter the trap, move freely, their antennae, back surface, legs, etc. touch the top surface of the trap surface 2 or the adhesive layer 4 on the peripheral surface of the fixing projection 3 to capture the adhesive. Is done. Since the distance between the trapping surface 10 and the adhesive layer 4 on the bottom surface of the trapping surface 2 or the trapping convex portion 5 becomes narrower toward the center portion (back side), the trapping becomes easier.

  In addition, the adhesive trap for trapping insects according to the present invention can be colored black, white, or another color for attracting insects, imparting light-shielding properties, and confirming trapped insects. When the light-shielding property is imparted to the adhesive trap by coloring, the trapping surface 2 is not directly irradiated with light, so that the effect of capturing microwalking insects having negative phototacticity is improved, which is preferable. The method of coloring the pressure-sensitive adhesive trap is not particularly limited, but the base material and / or the pressure-sensitive adhesive layer may be colored by mixing a pigment or a dye with the constituent material, or the surface of the pressure-sensitive trap, or A method of providing a coloring layer between layers can be applied. The coloring can be performed not only on the entire surface of the adhesive trap but also on a part thereof, and light and dark can be generated on the trap surface 2 by external light.

  Furthermore, in the adhesive trap for trapping insects according to the present invention, another layer can be provided on the surface of the substrate 1 opposite to the trap surface 2. For example, to provide a protective layer, to protect the surface of the adhesive trap, or, or to provide an ink receiving layer, or without, to form a printing layer, to display information necessary as an adhesive trap, and, further, A second adhesive layer is provided on a part of the entire surface, such as a solid or a stripe, so that not only a micro-walking insect can be captured on the trap surface 2 of the adhesive trap, but also a walking insect and / or a flying insect on the second adhesive layer surface. Can be captured.

  As described above, the insect trap adhesive trap according to the present invention is used in such a manner that one surface of the substrate is a trap surface having adhesiveness, and the trap surface is disposed so as to face the trap arrangement surface, At the time of use, there is no step in the entry path of insects, so it is not necessary for crawling insects and mites to walk on the adhesive surface, and it is possible to catch as long as they enter under the trap surface, The trapping efficiency is significantly improved compared to traps that need to crawl on sticky surfaces, and it can be easily placed on the side, top, inside, etc. of various facilities and equipment, and monitoring and monitoring of micro-walking insects Its industrial applicability is extremely large because it has the effect of being able to be effectively used for capture.
