<Summary>
It can be understood from the above test 1 and test 2 that when an ant poison bait container 30 provided with the container body 10 according to the first and second embodiments is installed at a place where an ant appears and disappears, the ant enters the ant poison bait container from the entrance 10E. 30, and only there is a low partition 10G having a space between the lid 20 and the ant in the passage, and surprisingly, the ants can overcome the low partition 10G and do not walk around the bank 10D. And many people started climbing the bank 10D without making a U-turn, and as a result, they stepped into the poison bait storage section 10P with a high bank climb rate (80% for Tobiro keari and 60% for black ants) ), The situation where the poison bait was carried out from the poison bait storage part 10P could be confirmed.
On the other hand, in the case of the container body 100 of the conventional ant poison bait container of FIG. 9 that does not include the low partition 10G in the passage, there is no chance of climbing the inclined wall 100S of the bank portion 100D. There were few ants trying to climb the inclined wall 100S of the bank portion 100D only by continuing to walk with the bottom 100B between the bank portions 100D as a passage (15% for Tobiro keari and 40% for black ants).
Further, FIG. 8 is provided with a high partition wall 400K between the peripheral wall portion 400A and the flat portion 400H of the bank portion 400D that has no space between the lid body 20 and blocks the circumferential passage of the flat portion 400H. In the case of the container body 400 of the ant poison bait container of the reference example, the partition wall 400K that rises much higher than its total height H gives caution because the ants cannot walk on the bank 400D in the circumferential direction. There were few ants trying to climb the sloped wall 400S of the bank portion 400D (20% in Tobiro Keari) because of a U-turn.
In this way, the height between the peripheral wall portion 10A and the bank portion 10D is almost the same height as the total height H of the ants (the length of the flying ants is 2.5 mm to 3.5 mm, the size of the black ants is 4 mm to 6 mm). (For example, a height of about 3 mm is suitable for a small ant such as a flying squirrel, and a height of about 5 mm is suitable for a large ant such as a black ant, and can be adjusted within a range of about 2 to 5 mm.) When the low partition 10G having a space is formed, many ants begin to climb the bank portion 10D, and the bank climbing rate increases. This is because when the ant 300 confronts the low partition 10G, it is not easy to straddle higher than its own total height H, but as when confronting the partition wall 400K by sensing that there is a space at the top. It is thought that this is not for making a U-turn and for taking an action of moving sideways and bypassing the low partition 10G without getting over the low partition 10G.

Here, the features of the above-described embodiment of the ant poison bait container according to the present invention will be briefly summarized in the following items i to iv.

[I] An ant poison bait container 30 comprising a container main body 10 that contains an ant poison bait and a lid 20 that covers the container main body 10;
The container body 10 includes a flat bottom portion 10B, a peripheral wall portion 10A that is erected over 360 degrees all around the edge of the bottom portion 10B, and has an entrance 10E formed at a plurality of locations, and an inner side of the peripheral wall portion 10A. A bank portion 10D formed in the space over the entire circumference 360 degrees, and a poison bait storage section 10P surrounded by the bank portion 10D over the entire circumference 360 degrees,
A low partition having a space between the lid 10 and the bottom 10B between the peripheral wall 10A and the bank 10D in the vicinity of each doorway 10E so that ants get over the bank 10D. Ant poison bait container 30 in which 10G is formed.
[Ii] The ant poison bait container according to [i], wherein the poison bait storage portion 10P is partitioned into a plurality of poison bait storage portions 10P1 and 10P2 by a central partition wall 10C.
[Iii] The low partition 10G is formed between a part of the bank portion 10D surrounding the poison bait storage portions 10P1 and 10P2 partitioned by the central partition wall 10C and the peripheral wall portion 10A. The ant poison bait container according to [ii] above, wherein the height differs for each low partition 10G.
[Iv] The ant poison bait container according to any one of [i] to [iii] above, wherein a height of the low partition 10G is in a range of about 2 to 5 mm from the bottom 10B.

The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to each of those components and combinations thereof, and such modifications are also within the scope of the present invention.
This application is based on a Japanese patent application filed on December 6, 2011 (Japanese Patent Application No. 2011-267273, the contents of which are incorporated herein by reference).

As described above, in the ant poison bait container according to the present invention, by providing a low partition having a space between the lid so as to get over the bank in the vicinity of the entrance and exit, this may hinder ant walking behavior. Despite being low enough, it is only in the aisle, and ants surprisingly do not move around the bank and walk around the bank, and do not make a U-turn. At the same time, it will begin to climb the bank, and as a result, the rate of overcoming the bank can be increased.
