Description

[Detailed description of the invention] This invention relates to the improvement of a device for attracting and capturing cockroaches, which are sanitary pests that crawl in kitchens and the like.

Conventional cockroach traps attract cockroaches using a chemical that emits a scent that cockroaches like, and when they get close to the attractant, they come into contact with an adhesive layer and capture the cockroaches using the adhesive force. If the adhesive layer is covered with dead cockroaches, they can easily escape, making it necessary to replace the trap frequently. In addition, conventional traps have an open entrance and exit, so the inside of the trap inside the trap is exposed. The drawback was that the corpses of cockroaches could be seen, creating a sense of filth and discomfort.

This invention solves the above-mentioned problems with conventional cockroach traps, and its purpose is to attract cockroaches by mixing not only an attractant but also a killer, and sealing the attracted cockroaches with a rotating lid. To provide a cockroach trap capable of catching cockroaches by dropping them into the trap or by crawling through a gap in the periphery of the lid which has resilience in the direction of closing the lid.

Details of this invention will be explained below based on embodiments shown in the accompanying drawings.

In the figure, 1 is a horizontal rectangular box made of cardboard. This box body is folded flat before use, and can also be made into a horizontally long rectangular cylindrical box when used.

The inside of the box 1 is divided into a large compartment 4 and a small compartment 5 by a partition wall 3 having a large number of small holes 2.

A large window hole 7 is formed on the upper surface of the large compartment 4 except for the peripheral edge 6, and this window hole is closed by a rotary lid 8 and is provided with restorability in the direction of always closing the lid.

9 is a rotation axis of the rotary lid 8, and 10 is a weight for providing restorability in the direction of closing the lid.

The rotary lid 8 shown is a separate member from the box body 1, and the plate-shaped inclined passage 11 reaching from the floor to the top outside the large compartment 4 is cut along the window hole 7 along a perforation (not shown). It is reversed.

The rotary lid 8 is made of plastic so that cockroaches can easily slip on it. Reference numeral 12 denotes a frame made of plastic material that reinforces the edge of the window hole 7, and a short cylindrical portion 13 for preventing cockroaches from returning hangs down from the lower surface of this frame.

A container 15 filled with a cockroach attractant 14 is loaded into the small compartment 5, and a groove 16 formed in the center of the upper surface of the retractable lid 8 is also filled with the attractant 14a, and this attractant 14a is assembled as a cockroach trap. The area up to the point is sealed with cellophane 17 grade.

An adhesive layer 18 is formed on the inner bottom surface of the large compartment 4.

The attractants used in this cockroach trap include, for example, roasted flour, boric acid powder, sugar, crushed onions,
It is made by mixing and kneading milk, etc., and cockroaches are attracted by the aroma emitted by roasted flour, sweeteners, crushed vegetables, etc., and when they approach the insecticide and eat it, they are killed by boric acid, which is the main insecticidal agent. It is reached.

This cockroach trap has the structure described above, and the interior of the horizontally long rectangular box is divided into two chambers, a large compartment and a small compartment, by a partition wall that deviates from the inside. A hole is provided and this window hole is closed with a rotating lid, and the restorability is always given in the closed direction.A cockroach attractant is loaded or filled into the groove formed in the small compartment and the center of the upper surface of the rotating lid, and the partition wall is porous. As a result, the fragrance of the cockroach-killing agent inside the small compartment was made to leak through the small gap between the window hole and the rotating lid that closes it, and a plate-shaped inclined passage was formed outside the large compartment to guide the cockroaches to the window hole. Attracted by the favorable aroma, they reach the rotating lid and flock to the attractant on the rotating lid. At the same time, they are attracted by the aroma flowing out from the circumferential side of the rotating lid and move to the circumferential side of the lid. At the same time, the balance of the lid is lost and it rotates, causing the insects to The cockroaches that sit on the box fall into the large compartment and are captured by the adhesive layer formed on the inner bottom surface of the large compartment, and are captured one after another without escaping out of the box again.

Note that this cockroach trap does not have an open entrance like conventional traps, so you cannot see the unpleasant corpses of captured cockroaches from the outside, but if the rotating lid is made of transparent material, you can check the capture status inside through the rotating lid. This allows you to judge when it is time to replace the trap.
