  By the way, in the insect trap of patent document 1, the filter part is hold | maintained at the container by the passage prevention part which has a bellows shape. Therefore, this insect trap is manufactured in the factory as a finished product in which the container, the filter unit, and the passage blocking unit are integrated. Therefore, in order to form a mosquito trap (or trap) more simply, there is room for improvement in the trap of Patent Document 1.

  The present invention has been made in view of such a problem, and has been obtained in an attempt to provide a bow-fla stopper that can be formed very easily and that can easily attract mosquitoes to a trapping net in a container. is there.

One aspect of the present invention is a boufrastopper for capturing mosquito eggs and bouula born from eggs,
A container formed in a bottomed cylindrical shape;
And a trapping net that is formed of a resin having a black color on the entire surface and that is disposed in the container, covers the opening hole of the container, and floats on the surface of water stored in the container. It is in the stopper.

The above-mentioned bow-fla stopper can be formed very simply by arranging water and a trapping net in the container. Further, the container and the catch net can be manufactured separately, and the bow-fla stopper can be manufactured very easily.
Moreover, when the capture net exhibits a black color, it is possible to easily attract the mosquitoes to the capture net in the container using the habit of a mosquito who likes black.

  Therefore, according to the above-mentioned bow-fla stopper, it can be formed very easily and mosquitoes can be easily attracted to the trapping net in the container.

A preferred embodiment of the above-described bow-fla stopper will be described.
The container may be made of metal and have an inner peripheral surface on which the metal surface is visually recognized, and the inner peripheral surface may be configured to reflect and reflect the black color of the capture net.
In this case, when the capture net exhibiting black color is arranged in the container, the black color of the capture net is reflected by the metal surface visible on the inner peripheral surface of the container, and the capture inner surface of the container The black color of the net is projected. Thereby, not only the capture net exhibits a black color, but also a state in which the inner peripheral surface of the container exhibits a color close to black can be easily formed. Therefore, mosquitoes can be easily attracted to the inside of the container and the catch net by utilizing the behavior of mosquitoes who prefer black.

Moreover, the said container is good also as what reused the empty container for commercially available spiral mosquito coils.
In this case, the bow-fla stopper can be formed very easily using the container (metal can) after the spiral mosquito coil has been taken out. This eliminates the need to manufacture the bow-fla stopper as a finished product in the factory.
Moreover, the container for spiral mosquito coils is made of a plated steel plate for rust prevention. Therefore, a state in which the inner peripheral surface of the container exhibits a color close to black can be formed without processing the empty container for the spiral mosquito coil.

The container may be formed of a resin whose entire surface is black.
In this case, a state where the inner peripheral surface and the outer peripheral surface of the container are black can be formed without performing secondary processing such as painting.
A container can be shape | molded, for example using the black compound of a polypropylene resin.

  Further, the container may have a bottomed cylindrical shape having a triangular, quadrangular, or polygonal cross section, for example, in addition to the bottomed cylindrical shape having a circular cross section. Regardless of the cross-sectional shape of the container, the trapping net is formed in accordance with the cross-sectional shape of the container.

Hereinafter, a preferred embodiment of the above-described bow-fla stopper will be described with reference to the drawings.
(Embodiment 1)
The bow-fla stopper 1 of this form is also called an insect trap and is for catching a mosquito egg and a bow-fla produced from the egg. As shown in FIGS. 1 and 2, the bow-fla stopper 1 includes a metal container 2 and a resin trapping net 4. The container 2 is formed in a bottomed cylindrical shape and has an inner peripheral surface 201 on which a metal surface is visually recognized. The trapping net 4 is formed of a resin having a black surface as a whole, and is disposed in the container 2 to cover the opening hole 202 of the container 2 and to store the water surface W1 of the water W stored in the container 2. Is something that comes to mind. The inner peripheral surface 201 of the container 2 is configured to exhibit a black color by reflecting the black color of the capture net 4 and projecting it. In FIG. 2, the reflected light that the inner peripheral surface 201 of the container 2 looks black is indicated by an arrow X.

Hereinafter, the bow-fla stopper 1 of this embodiment will be described in detail.
When the bow-fla stopper 1 is disposed at an intended outdoor location, the water W and the capture net 4 are disposed in the container 2. The water W arranged in the container 2 can be tap water, rain water, river water, or the like. In particular, the water W in the container 2 can be saved as rainwater that accumulates in rainy weather, thereby saving the trouble of adding water to the container 2.

  The container 2 of the bow-fla stopper 1 may be a container made of a plated steel plate, or a container (metal can) 2 in which a spiral mosquito coil is stored and sold (recycled).

  As shown in FIG. 2, the container 2 includes a bottom plate portion 21 and a cylindrical plate portion 22 that is provided in a cylindrical shape from the outer periphery of the bottom plate portion 21. The cylindrical plate portion 22 of the container 2 is provided with a pair of attachment holes 25 that open at positions facing each other, and a handle 3 that is attached across the pair of attachment holes 25. The pair of mounting holes 25 and the handle 3 are already provided in the container 2 when the spiral mosquito coil is stored and sold.

  The cylindrical plate portion 22 is formed in a cylindrical shape having a constant inner diameter at each portion in the height direction. As shown in FIG. 3, a bead portion 24 that protrudes from the outer peripheral surface of the cylindrical plate portion 22 is formed at the upper end 23 of the opening of the cylindrical plate portion 22 in the container 2.

  As shown in FIG. 3, the trapping net 4 rises above the mounting end portions 31 by the mounting end portions 31 respectively inserted into the pair of mounting holes 25 in the handle 3 in a state of floating on the water surface W1. Is blocked. In a state where the handle 3 is attached to the container 2, a part of each attachment end portion 31 of the handle 3 protrudes from the inner peripheral surface 201 of the container 2 to the inner peripheral side.

  Then, by using a part of each mounting end 31 protruding from the inner peripheral surface 201 of the container 2, the capture net 4 floating on the water surface W <b> 1 is prevented from rising, and the capture net 4 is unexpectedly moved to the outside of the container 2. It can be prevented from being taken out. Further, by using each attachment end portion 31 of the handle 3, a structure for preventing the catch net 4 from coming off can be formed.

  The capture net 4 is disposed in the container 2 in a state of being inclined with respect to the opening hole 202 of the container 2. Then, the capture net 4 is disposed below each attachment end 31 so that the capture net 4 does not get caught on a part of each attachment end 31 protruding from the inner peripheral surface 201 of the container 2.

  As shown in FIGS. 1 and 2, when the catch net 4 is disposed below each attachment end 31 in the container 2, the opening hole 202 of the container 2 is covered (closed). In order to make it possible to dispose the capture net 4 in the container 2, the outer diameter of the capture net 4 is, for example, smaller by 0.5 to 2 mm in diameter than the inner diameter of the inner peripheral surface 201 of the container 2. .

  The expression that the opening hole 202 of the container 2 is covered with the capture net 4 means that as much gap as possible is not formed between the inner peripheral surface 201 of the container 2 and the outer peripheral surface of the capture net 4. Between the inner peripheral surface 201 of the container 2 and the outer peripheral surface of the capture net 4, a gap for allowing the capture net 4 to be disposed in the container 2 is always formed. Moreover, the expression that the opening hole 202 of the container 2 is covered with the capture net 4 is closed in a state where the opening hole 202 of the container 2 can be vented through a passage hole 411 described later of the capture net 4. Means that.

  As shown in FIG. 3, the container 2 is configured to allow the water W stored in the container 2 to flow out from the gaps S between the attachment end portions 31 and the attachment holes 25. In a state where each attachment end 31 of the handle 3 is inserted into each attachment hole 25, a gap S is formed between each attachment end 31 and each attachment hole 25. Therefore, when the amount of the water W stored in the container 2 increases and the water surface W1 rises to the height at which each attachment hole 25 is provided, the water W near the water surface W1 is separated from each attachment end 31. It can flow out to the outside of the container 2 from the gap S with each mounting hole 25.

  In particular, when the bow-fla stopper 1 is used outdoors, when water W such as rainwater flows out from the gap S, the amount of water W in the container 2 is set to an appropriate amount for the trapping net 4 to float near the water surface W1. Can be adjusted. Further, by utilizing the gap S, an overflow structure of the water W can be formed without any modification to the container 2.

  As shown in FIG. 3, the trapping net 4 allows the net part 41 to pass through the mosquito eggs while forming a large number of passage holes 411 that do not allow the passage of mosquitoes. 41 and a protruding outer edge portion 42 protruding upward. The net 41 is formed along a virtual plane, and the outer peripheral surface of the projecting outer edge 42 is formed in a circular shape along the inner peripheral surface 201 of the container 2.

  Since the protruding outer edge portion 42 is provided upward from the net portion 41, a state in which the entire net portion 41 is in contact with the water surface W1 can be easily formed. An air phase is not formed between the net 41 and the water surface W1.

  The size of the passage hole 411 formed in the mesh part 41 can be set so that the equivalent diameter of a virtual circle inscribed inside the passage hole 411 is φ2.0 to 2.5 mm. When the passage hole 411 is formed in a square shape, the length of each side of the passage hole 411 is the same as the equivalent diameter of the virtual circle.

The entire capture net 4, that is, the net part 41 and the protruding outer edge part 42 are formed as a resin molded product by injection molding or the like. The entire catch net 4 is formed of a black polypropylene resin. The capture net 4 can be formed of various resins that can be easily molded.
As shown in FIG. 2, a knob 43 is provided at the center of the capture net 4 to easily take out the capture net 4 floating on the water surface W <b> 1 from the container 2.

  As shown in FIG. 3, a concave portion 43 is formed on the lower surface of the protruding outer edge portion 42 for storing air between the water surface W1. The projecting outer edge portion 42 was formed from the outer edge portion of the capture net 4 to the inner peripheral side standing portion 421 that stands perpendicular to the virtual plane on which the capture net 4 was formed, and from the inner peripheral side standing portion 421 toward the outer peripheral side. It has the upper surface part 422 and the outer peripheral side standing part 423 provided perpendicularly to the virtual plane from the upper surface part 422 so as to face the outer peripheral side of the inner peripheral side standing part 421. The concave portion 43 is formed by being surrounded by an inner peripheral side standing portion 421, an upper surface portion 422, and an outer peripheral side standing portion 423.

  Since the trapping net 4 is formed of a resin having a specific gravity smaller than that of the water W, the trapping net 4 can float on the water surface W1 without a special shape. However, by forming the recess 43 in the capture net 4, air can be retained in the recess 43 of the capture net 4 floating on the water surface W1, and the capture net 4 can be more easily floated on the water surface W1.

  The upper surface of the upper surface portion 422 is formed in a tapered shape in order to prevent water W from remaining on the upper surface portion 422. The upper surface of the upper surface portion 422 of this embodiment is formed in a tapered shape that descends toward the inner peripheral side. Note that the upper surface of the upper surface portion 422 may be formed in various tapered shapes, for example, may be formed in a tapered shape that descends toward the outer peripheral side. In addition, the upper surface of the upper surface portion 422 has a mountain shape, that is, a taper shape in which the inner peripheral side portion descends toward the inner peripheral side with the radial intermediate position of the upper surface portion 422 as a boundary, and the outer peripheral side You may have the taper shape which falls as a part goes to an outer peripheral side.

  In addition, the lower side shown in this embodiment means the vertical direction when the container 2 is arranged at an intended place, and the upper side is an upper side in the vertical direction when the container 2 is arranged at an intended place. I mean.

The bow-fla stopper 1 can capture mosquito eggs and bow-flas as follows.
When the bow-fla stopper 1 is placed outdoors or indoors at an intended place, mosquitoes as adults are attracted into the container 2 by the black color of the catching net 4 and the black color projected on the inner peripheral surface of the container. The And it is thought that the mosquito which stopped on the net part 41 of the capture net 4 lays eggs toward the water surface W1 in contact with the net part 41 or the net part 41. The spawned mosquito eggs sink into the water W through the passage hole 411 in the net 41.

  Next, from the egg in the water W, a owl is born as a larva, and the owl grows as an adult mosquito through an onibo fla. At this time, since the net part 41 is in contact with the water surface W1, the bowfra cannot rise above the water surface W1. Therefore, the bowfra is trapped in the water W, cannot breathe when growing into a mosquito, and die in the water W.

  In the unlikely event that the mosquito has grown into an adult in the water W located below the capture net 4, the mosquito tries to fly out of the capture net 4. Even in this case, since the passage hole 411 of the net part 41 is smaller than the mosquito's physique, the grown mosquito cannot go out of the capture net 4 and is killed in the water W.

  Moreover, before the eggs in the water W grow into adult mosquitoes, the mosquitoes can be killed by appropriately treating the water W in the container 2 containing mosquito eggs, boufra, onibula, etc. . Specifically, the water W in the container 2 is discharged onto dry asphalt, concrete, or the like, or on hot asphalt, concrete, etc. on a sunny day in summer. You can kill mosquito eggs, bow flares, onibou flares, etc. Further, by heating the water W in the container 2 to a high temperature by any method, it is possible to kill mosquito eggs, boufra, onibo fla, etc. in the water W.

  The bow-fla stopper 1 of this embodiment can be formed very easily by preparing a container (metal can) 2 as a reusable product after taking out the spiral mosquito coil and a capture net 4. Thereby, it is not necessary to manufacture the finished product of the bow-fla stopper 1 in the factory. Further, by reusing the spiral mosquito coil 2 for the bow-fla stopper 1, it is possible to effectively use resources.

  The capture net 4 can be very easily formed by using a resin molded product. Further, since the capture net 4 is black, mosquitoes can easily approach the capture net 4.

  The metal surface constituting the inner peripheral surface 201 of the container 2 is subjected to a metal plating process aiming at effects such as corrosion prevention and rust prevention. And the inner peripheral surface 201 of the container 2 is exhibiting colors, such as silver and gold, with the metal surface by which the plating process etc. were performed. Therefore, it is not necessary to perform any processing on the inner peripheral surface 201 of the container 2, and it is only necessary to perform black coating, printing, or the like on the outer peripheral surface of the container 2 as necessary.

  When the capture net 4 exhibiting black color is disposed in the container 2, the black color of the capture net 4 is reflected by the metal surface visible on the inner peripheral surface 201 of the container 2. Then, the black of the capture net 4 is projected on the inner peripheral surface 201 of the container 2. The state in which black is projected on the inner peripheral surface 201 means that the capture net 4 is disposed in the container 2 as compared to the color of the inner peripheral surface 201 that is visually recognized when the capture net 4 is not disposed in the container 2. This means a state in which the color of the inner peripheral surface 201 that is visually recognized when visually recognized is visually recognized as a color close to black.

  In this way, depending on the state of the inner peripheral surface 201 of the container 2, not only the capture net 4 exhibits a black color, but also the inner peripheral surface 201 of the container 2 can be easily formed to exhibit a color close to black. it can. And the state where the inner peripheral surface 201 of the container 2 exhibits a color close to black can be formed without processing the container 2 of the spiral mosquito coil. Therefore, mosquitoes can be easily attracted to the inside of the container 2 and the capture net 4 using the habit of a mosquito who likes black.

  Therefore, according to the bow-fla stopper 1 of this embodiment, it can be formed very easily, and mosquitoes can be easily attracted to the inside of the container 2 and the capture net 4.

  The capture net 4 can be sold in a state of being accommodated in the container 2 together with, for example, a spiral mosquito coil. In this case, although the container 2 accommodates the spiral mosquito coil, it can be easily specified that the capture net 4 is used for the bow-fla stopper 1. The capture net 4 can also be sold separately from the spiral mosquito coils in the container 2. In this case, when the capture net 4 is sold, it is explained that the use of the capture net 4 is to be used as the bow-fla stopper 1 using the container 2 of the spiral mosquito coil. It can be easily identified that it is used for the bow-fla stopper 1.

(Embodiment 2)
In this embodiment, another configuration of the container 2 used for the bow-fla stopper 1 is shown.
Some of the spiral mosquito coils 2 are not provided with the handle 3. In the following case, the container 2 without the handle 3 can be used as the bow-fla stopper 1.

  Specifically, as shown in FIG. 4, even if the container 2 is not provided with the handle 3, the container 2 protrudes from the upper end 23 of the cylindrical plate 22 to the inner peripheral surface 201 of the cylindrical plate 22. When the ball edge portion 24 </ b> A to be formed is formed, the container 2 can be used as the bow flat stopper 1. In this case, the catch net 4 is prevented from rising above the bead portion 24A by the bead portion 24A in a state of floating on the water surface W1.

As shown in FIG. 4, the ball edge portion 24 has an opening upper end portion 23 of the cylindrical plate portion 22 bent perpendicularly to the inner peripheral side, and as shown in FIG. 5, the opening upper end portion 23 of the cylindrical plate portion 22 has an opening upper end portion 23. It may be one that overlaps the inner peripheral surface 201 of the cylindrical plate portion 22.
In this embodiment, when the water surface W1 of the water W in the container 2 rises and the ascent of the catch net 4 is prevented by the bead 24A, the water W in the container 2 flows from the opening upper end 23 of the container 2. It can overflow.

  Since the edge portion 24A protruding from the inner peripheral surface 201 is formed on the opening upper end portion 23 of the cylindrical plate portion 22 of the container 2, the capture net 4 cannot be disposed in the container 2 unless it is deformed. . Therefore, the capture net 4 of this embodiment is formed of an elastically deformable resin (including rubber) in order to enable the arrangement in the container 2. And the capture net | network 4 is elastically deformed and passes the inner peripheral side of the ball edge part 24A. Thereafter, the elastic deformation of the trapping net 4 returns to the original state, whereby a state where the trapping net 4 is arranged in the container 2 can be formed.

  The other configuration of the bow-fla stopper 1 of this embodiment is the same as that of the first embodiment. In addition, components and the like indicated by the same reference numerals as those in the first embodiment are the same as those in the first embodiment. Also in this embodiment, the same effects as those of the first embodiment can be obtained.

  In addition, this invention is not limited only to each embodiment, In the range which does not deviate from the summary, it can be comprised in different embodiment.
