Description

[Detailed Description of the Invention] The present invention relates to an insect-trapping adhesive sheet, and more specifically, to an insect-trapping adhesive sheet for trapping and exterminating insects such as cockroaches in general households.

Conventional insect traps include those in which an adhesive is uniformly applied to the surface of smooth paper or a synthetic resin film, or those in which the adhesive is extruded from a tube and applied in a fixed shape.

However, it has the disadvantages that once it sticks to the adhesive, only the legs are left behind, that it takes time and effort to apply the adhesive, and that it is expensive because a large amount of adhesive is used.

However, an object of the present invention is to improve the above-mentioned drawbacks and to provide a pressure-sensitive adhesive sheet for trapping insects that is simple, inexpensive, and capable of effectively trapping insects.

In other words, the gist of the present invention is that the concavities and convexities on the surface are 2 to 20 mm.
The insect-trapping pressure-sensitive adhesive sheet has pressure-sensitive adhesive layers formed on the surface of a substrate alternately provided at intervals, and has unevenness having a height difference of 0.5 to 10 degrees over the entire surface.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a plan view of one embodiment, and FIG. 2 is a plan view of an embodiment.
It is a sectional view taken along the -n' line.

In the figure, 1 is a convex portion, and 2 and 3 are concave portions.

4 is an adhesive layer, and 5 is a substrate made of polyethylene foam provided with unevenness.

The base body 5 made of polyethylene foam has a thickness of 5 mm, and is provided with corridor-like unevenness by embossing, and convex portions 1 and concave portions 2 are alternately provided from a concave portion 3 located approximately at the center of the sheet. The height difference between the convex portion 1 and the concave portions 2 and 3 is 3 mm.

The adhesive used in the present invention may be a synthetic resin adhesive or a rubber adhesive as long as it has strong adhesiveness.

Further, the substrate used in the present invention has concave portions and convex portions alternately provided on the surface at intervals of 2 to 20 mm, and the concave and convex portions are 0 mm.
．． It is sufficient if the height difference is 5 to 10 degrees.

The material of the substrate is not particularly limited, but paper, synthetic resin sheets, soft synthetic resin foam sheets, etc. are preferably used, and soft synthetic resin foam sheets are particularly preferably used.

Examples of the soft synthetic resin foam sheet include foam sheets of polyethylene, polyurethane, and the like.

The composition of the adhesive sheet for insect trapping of the present invention is as described above,
If an attractant for insects to be captured is sprinkled in the recess 3 located approximately in the middle of the adhesive sheet, the insects attracted by the attractant will pass over the adhesive sheet and be captured by the adhesive. Since the convexes and convexes with a height difference of 0.5 to 10 tom are provided at intervals of 2-2-2Q, the adhesive adheres not only to the limbs but also to the chest and abdomen, making it extremely easy to catch insects.

In addition, since the adhesive adheres not only to the limbs but also to the thorax and abdomen, the adhesive area is unusually wide, and even if the adhesive layer is thin, it can be easily caught and manufactured at low cost.
