Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trap which can reliably catch insects such as cockroaches.

[0002]

2. Description of the Related Art Conventionally, a bottom plate having an adhesive layer and a side plate and a ceiling plate provided on both sides of the bottom plate are separately provided along a fold line on a single sheet. An insect trap configured by engaging and assembling the ceiling plates so that the adhesive layer is located on the inner surface,
It is widely used to capture insects such as cockroaches (for example, Japanese Utility Model Application Laid-Open No. 61-191780). Such insect traps are designed so that the attractant is mixed with the adhesive itself or the attractant is arranged on the surface of the adhesive layer to attract cockroaches and be captured by the adhesive force of the adhesive. I have.

[0003] In addition, insects such as cockroaches often have a habit of preferring a narrow and dark place. Therefore, insect traps are generally configured to be flat and dark inside. The flat shape of this trap is convenient for being placed and used in a state where it is pushed into a narrow place such as a lower part of furniture which is a passage of insects such as cockroaches.

[0004] A conventional general insect trap is shown in FIG.
As shown in the figure, on the surface of one sheet material, a side plate 38 divided by a fold line 37 and a side plate 42 divided by a fold line 41 from the bottom plate 36 are provided on opposite sides. As shown in FIG. 7, the assembling state of the sheet material includes an end face entrance 43 formed by cutting out both side faces of the insect trap 35 at the time of assembly, and a side face entrance 39 formed by cutting out a surface portion of the side plate 38. Is provided. And, with the intention of increasing the probability of capture, these entrances 39 and 4
Numeral 3 is provided on the four side surfaces, and is simply provided without any obstacles at the entrances 39 and 43 so that the target insects can easily enter.

[0005] The assembly of the sheet material is performed by the side plates 38.
At the fold line 37 and the handle 4
The part 0 is bent outside at the fold line and overlapped. Then
The lugs 42a of the side plates 42 on both sides are bent inward at the fold line 44, and a cut line 45 provided at the center of the edge of the lug 42a is inserted, thereby sandwiching the overlapped handles 40 from the end. This is achieved by fixing in a state. The adhesive layer 47 is formed on the surface of the substrate 46 by means such as coating or the like, and the substrate 46 is provided on the surface of the bottom plate 36 of the insect trap 35. 48 is an installation surface of the insect trap 35.

[0006]

However, in the above-mentioned conventional insect trap 35, the side entrance 39 and the end entrance 43 are merely provided, so that, for example, a long-footed and physically strong like a cockroach adult. Some insects may not be reliably captured. That is, the adult cockroaches are attracted, enter the trap 35 from the side entrance 39 and the end entrance 43, and reach the surface of the adhesive layer 47. In this case, side entrance 3
9 and the end face entrance 43 do not have any obstacles, so the entry is easy.
And near the end face entrance 43 in many cases. Even if the cockroaches are captured by the adhesive layer 47 near the entrance as described above, the adult cockroaches can escape from the entrance by their long legs and physical strength.

[0007] This type of insect trap 35 is installed and used in a fixed place for a long period of time. Therefore, insect trap 3
Since the adhesive performance of the pressure-sensitive adhesive layer 47 of No. 5 is also reduced, if the legs of insects that roam like cockroaches only once contact the surface of the pressure-sensitive adhesive layer, the insects that have physical strength on their long legs cannot be used. There are times when we can't reliably capture.

Accordingly, an object of the present invention is to provide an insect trap which can surely capture insects such as cockroaches or enhance the catch rate with a simple configuration and economically.

[0009]

In order to achieve the above object, the insect trap of the present invention comprises a bottom plate having an adhesive layer on one sheet, a side plate and a ceiling plate on both sides of the bottom plate. Are provided separately by fold lines, bent by these fold lines, and assembled by engaging the ceiling plates so that the adhesive layer is located on the inner surface, thereby forming end face entrances at both end faces, respectively. A cut line is formed in the side plate surface to form a side entrance, and a jump piece connected to a lower edge portion of the entrance hole forming the side entrance is provided in a state inclined inward. It is characterized by.

In the insect trap of the present invention described above, a cutout line is formed in the side plate surface of the side plate of the assembled trap to form a side entrance, and the lower edge of the entrance hole forming the side entrance is formed. Is provided in a state of being inclined inward, so that this jumping piece is a kind of obstacle. Therefore, in order for adult cockroaches to enter the trap from the side entrance, it is necessary to get over the above-mentioned jumping piece, so that the adult cockroach gets over the jumping piece and jumps down onto the adhesive layer surface. Will do.

As a result, most of the cockroaches and the like that have entered the trap will reach near the center of the adhesive layer. Therefore, even if an adult cockroach walks on the surface of the adhesive layer, the adhesive action of the adhesive is doubled each time it walks, and it becomes difficult to walk until it reaches the side entrance or other entrance where it has entered, Eventually, it will be captured by the adhesive layer.

[0012] Even if it is possible to reach the side entrance of the penetrating side, the jumping piece is provided in a state in which it is connected to the lower edge of the entrance hole and is inclined inward. Since it is extremely difficult to get over the jumping pieces, escape of adult cockroaches can be surely prevented.

In the insect trap of the present invention, the side entrance is formed by a concave cut line provided on the side plate surface, and the concave cut line is connected to the lower edge of the entrance hole of the side entrance. And a configuration in which a jump piece is formed by the ear piece cut out.

In the case where the jumping piece is formed by the ear piece cut out so as to be connected to the lower edge of the entrance hole of the side entrance by the cut line as described above, the cutout is formed on the surface of the sheet material. Since the side entrance and the jump piece can be formed only by forming the wire, the manufacturing is easy and economical.

The jumping piece formed by the ear piece cut out by the above-described concave cutting line has a convex shape at the center. Therefore, when relatively large insects such as adult cockroaches invade the trap, they will get over the jumping pieces as described above, but small insects such as cockroach larvae will It is possible to easily enter the trap from the side of the jumping piece. Therefore, the trapping rate of insects by the insect trap does not decrease due to the presence of the above-mentioned jumping pieces.

The insect trap of the present invention includes a configuration in which an edge connected to a bottom plate forming an end face entrance is provided as an inclined piece and is inclined inward.

Since the above-mentioned inclined piece is provided so as to be inclined inward at the lower edge of the entrance of the end face, it is a kind of obstruction when insects enter the trap. An obstacle to entry from the entrance. However, when an adult cockroach enters the trap, it enters a state of jumping and invading in the same manner as in the case of intrusion from the side entrance described above, so that the invading cockroach adult similarly enters the vicinity of the center of the adhesive layer. To reach. As a result, the same effect as in the case of the above-described jumping piece is exhibited. Further, as described above, since the inclined piece is configured to be inclined at the end face entrance and functions to prevent the invasion of insects, it also promotes the invasion from the aforementioned side entrance.

According to the insect trap configuration in which the inclined piece can be fixed by bending the connecting portion provided between the edge of the bottom plate and the edge of the side plate, the inclination of the inclined piece can be stabilized. Can be changed. It is preferable that a fold line or a dashed line for bending is provided in advance with respect to this connecting portion in order to clarify the bending position with respect to the inclined piece and facilitate the fixing operation. About this fold line etc.
For example, it can be configured by an inner bent line and an outer bent line.

In the insect trap of the present invention, fold lines are provided on the surface of a single sheet of paper or the like, and a bottom plate, a side plate, and a ceiling plate are formed, which are separated by these fold lines. It is the same as the conventional insect trap in that a fold line is provided on both sides of the bottom plate to assemble the side plate and the ceiling. Further, for example, a cut line may be provided on the ceiling plate surface above the ceiling plate, and a handle obtained by erecting a portion formed by the cut line may be provided.
