Description

[Technical Field]

[0001] The present disclosure relates to a sticky fly trap that traps flies with adhesive. [Background technology]

[0002] For example, as disclosed in Patent Documents 1 to 4, traps that capture flies with adhesive are known. The trap in Patent Document 1 is constructed by laminating an adhesive onto a sheet having a concentric pattern, an angular pattern, or the like. The trap in Patent Document 2 has an area where multiple patterns are arranged to form a reflective area that reflects an attractant color to pests. The trap in Patent Document 3 is equipped with an adhesive sheet having an island-in-a-sea pattern. Patent Documents 1 to 3 claim that such patterns have the effect of attracting flies. Furthermore, the trap in Patent Document 4 is equipped with an adhesive sheet with peaks and valleys formed, with bait placed in the valleys. Patent Document 4 claims that flies land on the corners, which are the peaks, of the adhesive sheet, and can be captured. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-84958 [Patent Document 2] Japanese Patent Application Publication No. 2019-135996 [Patent Document 3] Patent No. 6029690 [Patent Document 4] Japanese Utility Model Application Publication No. 54-174567 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is a demand for further improvements in the trapping efficiency of such sticky fly traps. In this regard, there is potential for further improvements in the attractiveness of traps that use patterns by devising the color and shape of the pattern, but it is not easy to find such a combination of color and shape. Furthermore, while it is conceivable to increase the number of traps by enlarging the patterned trapping surface, this would require a large amount of installation space.

[0005] On the other hand, for trapping at corners (edges), further improvements to the physical shape are possible, but it is difficult to make the physical shape of this type of adhesive trap complex. Also, even if many insects can be attracted to the edge, they cannot be attracted to other parts, which creates the problem of wasting adhesive on parts other than the edge.

[0006] The present disclosure has been made in view of the above points, and its object is to further improve the trapping efficiency of a sticky fly trap that uses an adhesive. [Means for solving the problem]

[0007] One embodiment for achieving the above object is a sticky fly trap that has a trapping surface coated with adhesive, and the trapping surface has a red background with a pattern of a color other than red. The pattern may include a plurality of white and / or black circles.

[0008] In another embodiment, a sticky fly trap may have a first trapping surface and a second trapping surface to which adhesive is attached, the first trapping surface and the second trapping surface are connected at a predetermined angle, and a first region of a predetermined width along the edge formed at the connection between the first trapping surface and the second trapping surface may be a first color. In this case, a second region adjacent to the first region may be a second color different from the first color.

[0009] In another embodiment, a sticky fly trap may have a first trapping surface and a second trapping surface to which adhesive is attached, the first trapping surface and the second trapping surface being connected at a predetermined angle, and the first trapping surface and the second trapping surface having a pattern that attracts flies. This pattern may be a color other than red on a red background. In this embodiment, the first trapping surface and the second trapping surface are connected at a predetermined angle, a first region of a predetermined width along an edge formed at the connection point between the first trapping surface and the second trapping surface may be a first color, and a second region adjacent to the first region may be a second color different from the first color.

[0010] In other words, if the sticky trap attracts flies solely through its pattern, it would be possible to increase the number of flies caught by enlarging the trapping surface, but this would require a large installation space. Therefore, by connecting the first and second patterned trapping surfaces at a predetermined angle, it is possible to increase the area of ​​the trapping surface while reducing the installation space.

[0011] Furthermore, by connecting the first and second capture surfaces at a predetermined angle, an edge is formed, which allows the edge to have an attractive effect and allows for more efficient capture. Conventional traps that use edges to attract worms do not attract worms in areas other than the edges, which wastes adhesive, but with the above configuration, the areas other than the edges can be attracted by the pattern, so no adhesive is wasted. [Effects of the Invention]

[0012] As described above, it is possible to further improve the efficiency of capturing flies while reducing the installation space. [Brief explanation of the drawings]

[0013] [Figure 1] 1 is a plan view of a sticky fly trap according to an embodiment of the present invention; [Figure 2] FIG. 1 is a perspective view of a sticky fly trap showing a first mode of use. [Figure 3] FIG. 10 is a perspective view of the sticky fly trap showing a second mode of use. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0015] Fig. 1 is a plan view of a sticky fly trap 1 (hereinafter simply referred to as trap 1) according to an embodiment of the present invention. Fig. 1 shows trap 1 stretched out along a plane (flat state), and when in use, it is folded in a three-dimensional state so that peaks and valleys are formed, as shown in Figs. 2 and 3. However, trap 1 may also be used in a flat state.

[0016] The trap 1 is composed of, for example, sheet-like or plate-like members. The members constituting the trap 1 are not particularly limited, but examples include paper, resin plates, etc., and it may also be a laminate of paper and resin sheets. The members constituting the trap 1 have shape-retaining properties that allow the shape to be maintained during use. For example, the hardness, material, etc. of the members constituting the trap 1 are set so that flat parts remain flat and folded parts maintain their folded shape during use (at least several weeks to about one month). Specific examples of the members constituting the trap 1 include thick paper, cardboard, corrugated cardboard, hard resin plates, etc.

[0017] As shown in FIG. 1 , the width and depth directions of the trap 1 are defined, but this definition is provided merely for the convenience of explaining the embodiment and does not limit the orientation of the trap 1 during actual use or the orientation of the trap 1 during manufacture or storage. If the width direction of the trap 1 is defined as the first direction of the trap 1, then the second direction perpendicular to the first direction in a planar view is the depth direction of the trap 1. The width and depth dimensions of the trap 1 may be the same, or one may be longer than the other. In this embodiment, the width dimension is set longer than the depth dimension when the trap 1 is in a flat state, but the width dimension may also be set shorter than the depth dimension.

[0018] Edges 1a, 1b on both sides of the width direction of trap 1 extend linearly in the depth direction and are parallel to each other. On the other hand, edges 1c, 1d on both sides of the depth direction of trap 1 have a shape in which multiple protrusions and recesses are formed alternately in the width direction. However, the shape of the outer edge of trap 1 is not limited to this and can be any shape. For example, edges 1a, 1b of trap 1 may have a shape in which multiple protrusions and recesses are formed alternately in the width direction. Also, for example, edges 1c, 1d of trap 1 may extend linearly in the width direction.

[0019] An adhesive is attached to the surface of the trap 1. This surface of the trap 1 constitutes the fly trapping surface 2. Any conventionally known adhesive can be used, and has enough adhesive strength to stick to the wings, legs, body, etc. of a fly that comes into contact with it, preventing the fly from flying away. The adhesive is applied to the trapping surface 2, making it difficult to peel off from the trapping surface 2. The adhesive is colorless and transparent, allowing the color and pattern formed on the trapping surface 2 to be seen through the adhesive. The adhesive only needs to be translucent enough to allow the trapping surface 2 to be seen, and may be lightly colored. The thickness of the adhesive layer formed by the adhesive can be set as desired.

[0020] The capture surface 2 includes a plurality of first capture surfaces 2a, 2c, and 2e and a plurality of second capture surfaces 2b, 2d, and 2f. From one side to the other in the width direction of the trap 1, the first capture surface 2a, the second capture surface 2b, the first capture surface 2c, the second capture surface 2d, the first capture surface 2e, and the second capture surface 2f are arranged in this order. The first capture surface 2a and the second capture surface 2b are adjacent to each other, and the first capture surface 2c and the second capture surface 2d are adjacent to each other, and the first capture surface 2e and the second capture surface 2f are adjacent to each other. The second capture surface 2b and the first capture surface 2c are adjacent to each other, and the second capture surface 2d and the first capture surface 2e are adjacent to each other. The first capture surface 2a and the second capture surface 2b form a pair, the first capture surface 2c and the second capture surface 2d form a pair, and the first capture surface 2e and the second capture surface 2f form a pair, so that three pairs of capture surfaces are provided in one trap 1. Although not shown, only one pair of first capture surface and second capture surface may be provided, or two, four or more pairs of first capture surface and second capture surface may be provided.

[0021] A first opening 3 is formed in the depth direction center of the first trapping surface 2a, located at one end of the width direction of the trap 1. A second opening 4 is formed in the depth direction center of the second trapping surface 2f, located at the other end of the width direction of the trap 1. The first opening 3 and the second opening 4 are formed to penetrate the trap 1 in the thickness direction and are, for example, circular. A hook-shaped hanging device 100, as shown in FIG. 3, can be passed through the first opening 3 and the second opening 4. Although not shown, members such as strings, threads, or ropes can also be passed through the first opening 3 and the second opening 4. By using the hanging device 100, strings, threads, or ropes, the trap 1 can be suspended and used.

[0022] 1, the imaginary line showing the boundary between the first capture surface 2a and the second capture surface 2b is shown as a dashed line as the first boundary line L1, the imaginary line showing the boundary between the second capture surface 2b and the first capture surface 2c is shown as a dashed line as the second boundary line L2, the imaginary line showing the boundary between the first capture surface 2c and the second capture surface 2d is shown as a dashed line as the third boundary line L3, the imaginary line showing the boundary between the second capture surface 2d and the first capture surface 2e is shown as a dashed line as the fourth boundary line L4, and the imaginary line showing the boundary between the first capture surface 2e and the second capture surface 2f is shown as a dashed line as the fifth boundary line L5. The first to fifth boundary lines L1 to L5 are straight lines extending in the depth direction and are parallel to each other.

[0023] At the time of distribution and sale, a release paper (not shown) is provided on the trap surface 2 of the trap 1, and the trap 1 is folded along the first to fifth boundary lines L1 to L5 and packaged in a folded state. That is, the first trap surface 2a and the second trap surface 2b are folded along the first boundary line L1 to form a mountain fold. The second trap surface 2b and the first trap surface 2c are folded along the second boundary line L2 to form a valley fold. The first trap surface 2c and the second trap surface 2d are folded along the third boundary line L3 to form a mountain fold. The second trap surface 2d and the first trap surface 2e are folded along the fourth boundary line L4 to form a valley fold. The first trap surface 2e and the second trap surface 2f are folded along the fifth boundary line L5 to form a mountain fold.

[0024] Thus, trap 1 is folded and packaged for distribution. When first using trap 1, the user unfolds the folded trap 1, unfolding it into a three-dimensional shape with multiple alternating peaks and valleys as shown in Figures 2 and 3. The user then begins use by peeling off the release paper provided on trapping surface 2 to expose the adhesive. Note that trap 1 may be in a flat state as shown in Figure 1 for distribution, and when first using trap 1, the user may fold it themselves into the three-dimensional shape shown in Figures 2 and 3.

[0025] In this embodiment, the first to fifth boundary lines L1 to L5 are provided to create three peaks and two valleys, but the present invention is not limited to this and it is sufficient if there is one or more peaks. Also, Fig. 2 shows a configuration in which the trap is placed on a support surface (not shown) such as a table or desk, and the rear surface of the valleys of the trap 1 and the edges 1a, 1b on both sides in the width direction come into contact with the support surface.

[0026] The first capture surface 2a and the second capture surface 2b, which are bent in a mountain shape at the first boundary line L1, are connected at a predetermined angle. Specifically, the angle formed between the first capture surface 2a and the second capture surface 2b is greater than 30 degrees and less than 150 degrees. Because the first capture surface 2a and the second capture surface 2b are connected at such an angle, a first edge E1 (or a first corner) extending linearly in the depth direction is formed at the connection point between the first capture surface 2a and the second capture surface 2b.

[0027] Furthermore, the first capture surface 2c and the second capture surface 2d, which are bent at the third boundary line L3, are also connected at a predetermined angle, so that a second edge E2 (or a second corner) extending linearly in the depth direction is formed at the connection point between the first capture surface 2c and the second capture surface 2d. Furthermore, the first capture surface 2e and the second capture surface 2f, which are bent at the fifth boundary line L5, are also connected at a predetermined angle, so that a third edge E3 (or a third corner) extending linearly in the depth direction is formed at the connection point between the first capture surface 2e and the second capture surface 2f. The angles formed by the first capture surface 2a and the second capture surface 2b, the first capture surface 2c and the second capture surface 2d, and the first capture surface 2e and the second capture surface 2f may all be the same or different from each other. Furthermore, since it is sufficient that at least one edge is formed on the trap 1, the trap 1 may be bent so that any one or two of the first to third edges E1 to E3 are not formed.

[0028] If the angle is too large, the edges E1 to E3 will not stand out, making it difficult to obtain the attracting effect of the edges described below, and the installation area of ​​the trap 1 will also increase. If the angle is too small, the patterns between the edges E1 to E3 will be difficult for flies to see, making it difficult to obtain the attracting effect of the patterns described below. As mentioned above, this angle can be greater than 30 degrees and less than 150 degrees, and more preferably greater than 60 degrees and less than 120 degrees. More specifically, it can be an angle of about 90 degrees.

[0029] Three first regions 3a, 3b, and 3c are formed on the trapping surface 2 along the edges E1 to E3. The first region 3a has an elongated shape extending along the first edge E1, and has a predetermined width on each side in the width direction as viewed from the first edge E1. The first region 3b has an elongated shape extending along the second edge E2, and has a predetermined width on each side in the width direction as viewed from the second edge E2. The first region 3c has an elongated shape extending along the third edge E3, and has a predetermined width on each side in the width direction as viewed from the third edge E3. The longitudinal direction of the first regions 3a, 3b, and 3c coincides with the depth direction of the trap 1, and the width direction of the first regions 3a, 3b, and 3c coincides with the width direction of the trap 1. In this embodiment, the widths of the first regions 3a and 3c are set equal, and the width of the first region 3b is set wider than the width of the first region 3a, but this is not limited thereto, and the widths of the first regions 3a, 3b, and 3c may all be equal or may all be different. Also, in this embodiment, the widths of the first regions 3a, 3b, and 3c are constant in the depth direction, but this is not limited thereto, and the widths of the first regions 3a, 3b, and 3c may vary in the depth direction.

[0030] Additionally, six second regions 4a, 4b, 4c, 4d, 4e, and 4f are formed on the capture surface 2. The second region 4a is adjacent to the first region 3a and is formed on the first capture surface 2a. The second region 4b is adjacent to the first region 3a and is formed on the second capture surface 2b. The second region 4c is adjacent to the first region 3b and is formed on the first capture surface 2c. The second region 4d is adjacent to the first region 3b and is formed on the second capture surface 2d. The second region 4e is adjacent to the first region 3c and is formed on the first capture surface 2e. The second region 4f is adjacent to the first region 3c and is formed on the second capture surface 2f. That is, the areas on the capture surface 2 other than the first areas 3a, 3b, and 3c are the second areas 4a, 4b, 4c, 4d, 4e, and 4f, with the second areas 4b and 4c located between the first areas 3a and 3b, and the second areas 4d and 4e located between the first areas 3b and 3c. Note that the capture surface 2 may also have a third area formed other than the first areas 3a, 3b, and 3c and the second areas 4a, 4b, 4c, 4d, 4e, and 4f.

[0031] The adhesive is provided only in first regions 3a, 3b, 3c and second regions 4b, 4c, 4d, 4e, and is not provided in second region 4a on one side in the width direction or second region 4f on the other side in the width direction. In other words, since no adhesive is provided in second region 4a where first opening 3 is formed or second region 4f where second opening 4 is formed, the adhesive will not adhere to hands, hanging device 100, etc. when passing hanging device 100 through first opening 3 or second opening 4 as shown in Figure 3, for example. The adhesive may also be provided on the entire surface of capture surface 2.

[0032] The first regions 3a, 3b, and 3c are colored a first color, and the second regions 4a, 4b, 4c, 4d, 4e, and 4f are colored a second color different from the first color. The first color can be a lighter color than the second color. Examples of the first color include white, yellow, and gray. Examples of the second color include red, black, and green. As will be described in detail later, the second regions 4a, 4b, 4c, 4d, 4e, and 4f may have a pattern. In other words, the second regions 4a, 4b, 4c, 4d, 4e, and 4f are not necessarily solid colors. In this case, the "second color" refers to the color of the portions of the second regions 4a, 4b, 4c, 4d, 4e, and 4f other than the pattern, i.e., the background color.

[0033] In this embodiment, the second regions 4a and 4f are colored only red, but the other second regions 4b, 4c, 4d, and 4e have patterns of colors other than red on a red background. These patterns attract flies. For example, when a surface with this pattern and a surface without this pattern are placed in the same group of flies, more flies are attracted to the surface with this pattern. Patterns with such an attractive effect are formed in the second regions 4b, 4c, 4d, and 4e.

[0034] Specifically, wide areas of the second regions 4a, 4b, 4c, 4d, 4e, and 4f (the areas indicated by diagonal lines in each figure) are colored red. The second regions 4b, 4c, 4d, and 4e are patterned with a plurality of white and / or black circles. The pattern may consist of only white circles, only black circles, or a combination of white and black circles. The number of circles included in the pattern is not particularly limited, and may be one or more. The size of the circles included in the pattern is also not particularly limited, and may be set within the range of, for example, 1 mm to 50 mm in diameter. When the pattern includes multiple circles, the diameters of the circles may be different from each other or may all be the same. The circles may be located at the edges or centers of the second regions 4b, 4c, 4d, and 4e. When multiple circles are included, they may be arranged randomly. The pattern may include ellipses or ovals instead of circles, or may include ellipses or ovals in addition to circles.

[0035] In this embodiment, the trap 1 does not contain an attractant. The attractant here refers to a substance that attracts flies, including organic matter that serves as fly food and volatile chemicals that attract flies. In other words, the trap 1 of this embodiment attracts flies by its color, pattern, and shape, and can capture flies using adhesive, without using an attractant. However, this is not a limitation, and the trap 1 may contain an attractant. In this case, for example, fly food may be placed on the trapping surface 2, or an attractive chemical substance may be mixed into the adhesive.

[0036] (Fly attraction test) Next, we will explain the fly attraction test. A peat-grady chamber was used as the test equipment. Test traps were placed on the floor of the peat-grady chamber, and sticky control traps were placed at intervals. 25 male and 25 female house flies (Musca domestica) were released into the chamber, and the numbers of flies captured in the test and control traps were counted. The test lasted 8 hours. The relative number of flies captured in each test trap was calculated by dividing the number of flies captured in the test trap by the number of flies captured in the control trap.

[0037] (Edge color effect) First, as Example 1, a trap was prepared in which the first regions 3a, 3b, and 3c including the first to third edges E1 to E3, respectively, were colored white and the second regions 4a, 4b, 4c, 4d, 4e, and 4f were colored black (no pattern), and the trap was folded as shown in Figure 2. Also, as Comparative Example 1, a trap was prepared in which the first regions 3a, 3b, and 3c and the second regions 4a, 4b, 4c, 4d, 4e, and 4f were colored black (no pattern), and the trap was folded as shown in Figure 2 with the valleys colored white. Furthermore, as Comparative Example 2, a trap was prepared in which the first regions 3a, 3b, and 3c were colored white and the second regions 4a, 4b, 4c, 4d, 4e, and 4f were colored black (no pattern), and the trap was flat.

[0038] The test results are explained below. Comparing Example 1 and Comparative Example 1, the relative number of captures in Example 1 was 2.1 times that of Comparative Example 1. Comparing Example 1 and Comparative Example 2, the relative number of captures in Example 1 was 6 times that of Comparative Example 2. That is, it is clear that flies are attracted by forming the first to third edges E1 to E3, and that the number of captured flies increases significantly by coloring the areas along the first to third edges E1 to E3 white and coloring the other areas a color other than white. The reason for this is not entirely clear, but it is thought that by coloring the areas along the edges a lighter color than the other areas, the attracting effect of the edges is enhanced by the contrast.

[0039] (Effect of color in the second area) Next, as Example 2, a trap was prepared in which the first regions 3a, 3b, and 3c including the first to third edges E1 to E3, respectively, were colored white, and the second regions 4a, 4b, 4c, 4d, 4e, and 4f were colored red (no pattern), and the trap was bent as shown in Figure 2. Comparing Example 1 and Example 2, the relative number of flies captured in Example 2 was 1.6 times that of Example 1. In other words, it can be seen that by coloring the first to third edges E1 to E3 white and the other parts red, the number of flies captured was further increased.

[0040] (Pattern effect) In Example 3, a fly trap was prepared in which a fly-attracting pattern (a white-only circular pattern) similar to that of Example 2 was added, as shown in Figure 2. The circular pattern consisted of a mixture of circles of different diameters (circles with diameters of 2.2 cm, 1.8 cm, and 1.0 cm). Comparing Example 3 and Example 2, the relative number of flies captured in Example 3 was 1.2 times that of Example 2. This indicates that the white circular pattern significantly improves the fly-attracting effect. Furthermore, when a test was also conducted with a pattern consisting of regularly arranged circles of the same diameter, the number of flies captured was lower than in Example 3. This indicates that a pattern consisting of a mixture of circles of different diameters is preferable. Furthermore, tests were conducted with patterns including white illustrations and white arrow-shaped figures, and the number of flies captured was lower than in Example 3. This indicates that patterns with simple shapes, such as circular patterns, are preferable, rather than complex shapes such as illustrations and arrow-shaped figures.

[0041] Furthermore, as Example 4, a trap was prepared in which a fly-attracting pattern (both white and black circular patterns) as shown in Figure 2 was added to Example 2. As for the diameter of the circular patterns, a pattern was used in which circular patterns of different diameters were mixed, as in Example 3 above. Comparing Example 4 with Example 3, the relative number of flies caught in Example 4 was 1.8 times that of Example 3. Therefore, it can be seen that forming circular patterns in both a color that is lighter than red (the background color), such as white, and a color that is darker than red (the background color), such as black, significantly improves the fly-attracting effect.

[0042] (Effects of the embodiment) As described above, according to this embodiment, the capture surface to which the adhesive is attached has a pattern of a color other than red on a red background, which significantly improves the fly attracting effect, and therefore the fly capture efficiency can be increased while reducing the installation space of the trap 1.

[0043] Furthermore, by connecting the patterned first capture surfaces 2a, 2c, 2e and the second capture surfaces 2b, 2d, 2f at a predetermined angle, the area of ​​the capture surface 2 can be increased while reducing the installation space.

[0044] Furthermore, edges E1 to E3 are formed by connecting first capture surfaces 2a, 2c, and 2e and second capture surfaces 2b, 2d, and 2f at a predetermined angle, so that the edges E1 to E3 can exert an attracting effect and capture more efficiently. Furthermore, conventional traps did not attract insects in areas other than the edges E1 to E3, resulting in wasted adhesive, but according to this embodiment, areas other than the edges E1 to E3 can be attracted by the pattern, so no adhesive is wasted.

[0045] The above-described embodiments are merely examples in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. [Industrial Applicability]

[0046] As described above, the sticky fly trap according to the present invention can be used by being placed on a surface or by being suspended from a suspension tool. [Explanation of symbols]
