Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the configuration of a trapping device suitable for capturing flying insects such as flies.

[Prior Art] Conventionally, as a tool for capturing flying insects such as flies, fly paper with an adhesive coated on the surface of a hanging paper tape has been frequently used. As another example, an insect trap 25 as shown in FIG. 5 has come into use, mainly for capturing insects crawling on the floor, such as cockroaches.

This insect trap 25 is constructed by providing a rectangular sheet material 26 with an adhesive layer 27 on its center surface, and bending both sides 28 and 30 of the sheet material 26 toward the surface of the adhesive layer 27, respectively. When in use, the protrusion 29 at the extreme edge on the side part 28 is fitted into the recessed notch 31 at the extreme edge on the side part 30, so that it is constructed into a box shape. . Moreover, in this box shape, openings 33, 33 are provided on the end faces at symmetrical positions,
Further, openings 32 are provided on the side portions of each of the side portions 28 and 30.

[Problem to be solved by the invention] Regarding the former mentioned above, since the capture surface is completely exposed to the outside, it is suitable for capturing flying insects, but the captured insects are exposed as they are. Due to its condition, it is inevitable that it will feel unclean, and even when it is time to dispose of it, it will be extremely difficult to dispose of it due to the contamination.

Regarding the latter conventional insect trap 25, in its assembly configuration, the open portions 33 and 32...
They are relatively small and are suitable for capturing insects such as cockroaches that crawl on the floor, but are unsuitable for capturing flying insects such as flies. Also, insects are captured on the adhesive layer 27,
The capture position is in a place that can be easily seen from the mouth part 33. Furthermore, when disposing of the product, as shown in FIG. 6, it is important to disengage the protrusion 29 and the recessed part 31 and dispose of it in a reduced size, since there may be insects caught on the surface of the adhesive layer 27. is not possible.
Therefore, it must be disposed of while still in its box shape.

The purpose of this invention is to provide a sufficiently wide opening suitable for capturing flying insects, to prevent captured insects from being exposed to the outside during the period of use, and to close or sufficiently reduce the opening. To provide an insect trap that can be disposed of in an untreated state.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention has an insect trap configured as follows.

That is, two flexible sheet materials each having a crease extending diagonally from each corner of the rectangular shape to near the middle of the surface to form a concave portion are placed on the concave surface of at least the lower sheet material. Adhesive layers are provided, and these sheets are arranged one above the other with their recessed surfaces facing each other, and two bendable struts are bent outward at symmetrical positions between these sheets. It is characterized in that it is provided by fixing its both ends to the center of the corresponding peripheral edge of the material.

In the above-described features of the present invention, the flexible sheet material may be a plastic sheet material in addition to paper material. Further, the rectangular shape of the sheet material includes not only the original rectangular shape but also rectangular shapes such as those with rounded corners. Further, the position where the fold is formed does not have to completely coincide with the diagonal line of the rectangle, and the extreme end thereof may be located at a position offset from the diagonal line.

Further, the adhesive layer can be provided on the upper sheet material in the same manner as the lower sheet material, and the adhesive layer can be formed by applying an adhesive in a layered manner or by pasting an adhesive coated sheet.

In addition, the suitable conditions for the pillar part are that its function is to maintain the transient state during bending, and to reduce the distance between its ends to almost zero at the bending limit. In addition to having a bending function component, the support column may be made of a metal wire such as a lead wire, a plastic wire, etc., which is deformable but can maintain its shape when deformed. .

[Function] When operating each strut so that it becomes straight, the portion defined by the two folds on each sheet material to which the end of the strut is fixed is pressed inward, respectively. transformed. At this time, pressing force is generated from the corresponding corners on the other edges of each sheet material adjacent to this pressed-in portion, so that each of these edges protrudes outward into a circular arc. Deformed to take on a shape.

As a result, in this insect trap, the recesses in each sheet material were deepened, an opening was formed in the side surface where the support was provided, and the other side surfaces were made wider. A mouth will be formed.

Furthermore, the sizes of the opening and mouth described above can be freely adjusted depending on the degree of bending of each support portion.

Next, when each support column is bent to the maximum extent, each opening is almost closed, and each opening is positioned on the edge of each sheet material that constitutes the opening. As a result of the forces exerted by the folds delimiting the portions inwardly acting on each other, a nearly completely closed state is achieved. Also, at this time, the insect trap will have a flat shape as a whole, but since both sheets maintain their original concave shape due to their respective folds, there is a gap between both sheets. will still be held.

[Example] Next, an embodiment of the present invention will be described.

The insect trap 1 according to the embodiment is shown in the first state in the state at the time of its use.
As shown in the figure. This insect trap 1 consists of a lower sheet material 2, an upper sheet material 3, and symmetrically positioned pillars 12, 12 that mutually support these sheet materials 2, 3.

The lower sheet material 2 is formed by forming creases 4 extending diagonally from each corner of the rectangular shape to the middle part of the surface so as to create a recess, and pasting an adhesive sheet on the surface of the recess. This is the adhesive layer 5.

The upper sheet material 3 is made of the same paper material and has the same shape as the lower sheet material 2, but has a perforation 6 in the center of its surface, and a suspension string 7 is inserted into the perforation 6.
One end of is inserted through and fixed on the inner surface by a seal 8.

lower sheet material 2 downward and upper sheet material 3
are arranged above with their concave portions facing each other, and struts 12, 12 extend between the corresponding edge central portions of each of these sheet materials 2, 3 and fix the ends thereof, respectively. They are located at mutually symmetrical positions.

Further, this support portion 12 has joint portions 13 and 18 at both ends, respectively, which have grooves on the end faces. A bearing 15 is connected to the joint portion 13 via a column 14 so as to be perpendicular to the axis of the column 14 . This bearing 15
has a through hole along its axis, and has an opening 16 in the center of the side surface communicating with the through hole.
Reference numeral 17 denotes a locking portion protruding from the edge of the cutout 16 and provided at symmetrical positions. Further, a pillar portion 19 that can be inserted between the locking portions 17 and 17 described above is connected to the joint portion 18.
Although not shown, a through hole is provided near the end of the column 19. By fitting the end of the column 19 into the cutout 16 and inserting the support shaft 20 into the through hole on the bearing 15 so as to extend into the through hole, the column 14 and the column are connected. The section 19 is connected to the section 19. In this connection configuration, the support 19 is connected to the support shaft 20 with respect to the support 14.
It can be bent around.

Each of the above-mentioned sheet materials 2 and 3 of this support portion 12
The upward fixation is achieved by fitting the corresponding edges of the sheets 2 and 3 into the grooves of the joints 13 and 18, respectively.

As shown in FIG.
When the sheet materials 2 and 3 are manipulated so that the edges are straight, the edge portions 9 defined by the folds 4, 4, to which the ends of the struts 12 are fixed, move inward, respectively. A deeper accommodation recess 10 is formed in the shape of a push-in.

At this time, the support sections 12, 12 are placed on the insect trap 1.
Openings 23, 23 are formed on the side surface where the openings 23, 23 exist, and mouth portions 22, 22 are formed on the other side surface. Also, the edge 11 on each sheet material 2, 3 forming this opening 22
. . . exhibits an arcuate shape that simultaneously receives the acting force originating from the aforementioned insertion portions 9, 9 inwardly from both corresponding corners thereof and protrudes outwardly. Therefore, this mouth portion 22 is obtained in a more expanded state.

This configuration of the open portion during use is convenient for receiving flying insects, and since insects are captured on the surface of the adhesive layer 5 within the accommodation recess 10, they are easily exposed to the outside. Never.

In addition, since each of the support columns 12, 12 can be bent outward at an appropriate angle and maintained in that state, each of the opening portions 22 and each The size of the opening 23 can be adjusted and selected as appropriate. Note that the protrusion 21 on the side surface of the column 19 collides with the locking portion 17 and specifies the minimum position for bending the column 12 .

Next, when each support 12 is bent to the maximum extent, the joints 13 and 18 of each support 12 are almost overlapped, and the insect trap 1 as a whole is bent as shown in FIG. It becomes flat. Therefore, each opening 23 is in a substantially closed state, and each mouth 22 has its mouth edges 11', 1
It is in a completely closed state as shown at 1'.
This means that, for each mouth edge 11', 11', the force exerted by the corresponding fold lines 4, 4 on each sheet material 2, 3 will now protrude inward, respectively. It is from.

Furthermore, even in the above-mentioned operating state, as shown in FIG. There is a gap 24 inside between the three. Since such a gap 24 can still accommodate and hold the captured insects, the insect trap 1 can be deformed into a compact shape, that is, flat, and then disposed of.

[Effects of the invention] Since the invention is configured as described above,
It has the following effects.

First, since the insect trap is formed with its opening widened on its side, it is extremely effective in receiving flying insects.

In addition, the captured insects are housed in a deeper storage recess when used, and their presence is not easily exposed from the outside.
Its appearance remains clean even after long-term use.

Furthermore, when discarding the insect trap, the captured insects are sealed inside the container without being exposed to the outside, and are not crushed, making it possible to dispose of the insect trap in a compactly deformed state. Therefore, the disposal operation can be performed in a clean state.

In addition, it is convenient for disposable use because it is made of simple materials such as a sheet material and a support member with a simple functional structure, and can be assembled and used with extremely simple operations.
