Description

  The present invention relates to a rodenticide for extermination of rods, and particularly belongs to the technical field of a structure in which a poisonous bait for rodenticide is housed in a bag.

  2. Description of the Related Art Conventionally, as a method for exterminating sputum, there is known a method in which a sputum poison bait is eaten by a spider (for example, see Patent Documents 1 to 5). The rodenticide of Patent Document 1 includes a bag body that houses a poisonous bait for rodenticide inside, and the bag body is made of a non-woven fabric that has air permeability, and the rod can be lifted and brought back to the nest. It has a behavior induction part. This action induction part is comprised with the joining piece in a bag, and maintains the shape which protruded upwards at the time of installation of a rodenticide.

  The rodenticide of Patent Document 2 is a bagicide that is automatically packaged in a bag body. The bag body is provided with a seal portion that seals the non-woven fabric and a non-sealed portion that is not sealed, and the non-sealed portion is at least a predetermined range of the entire circumference of the bag body. Thereby, the range in which a seal | sticker part is formed is decreased and the eating rate of the poisoning bait for slaughter is aimed at.

  The rodenticide of Patent Document 3 is a bag made of nonwoven fabric. By setting the basis weight of the non-woven fabric constituting the bag body within a predetermined range, the bag easily breaks the bag body, and easily releases the induced odor emitted from the poison bait for slaughter to the outside of the bag body. Yes.

  In the rodenticide of Patent Document 4, the bag body is formed of a film. By setting the oxygen permeability and water vapor permeability of the film constituting the bag within a predetermined range, deterioration of the poisoning bait for slaughter over time is suppressed.

  The rodenticide of Patent Document 5 is a bag made of paper laminated with polyethylene. The repellency of wrinkles is reduced by setting the thickness of polyethylene to 10 to 30 μm.

Japanese Patent No. 4294575 Japanese Utility Model Publication No. 55-4241 JP 2007-230898 A Japanese National Patent Publication No. 10-506625 JP-A-1-238502

  By the way, in general, when using a rodenticide containing a poisonous bait for rodenticide in a bag body, the rodenticide is placed in a place where a rod is likely to come out. When a spider finds a slaughtering material outside the nest, it is brought back to the nest and eats a slaughter poison bait, and inside the nest, other spiders may also eat a slaughter poison bait. The removal effect can be enhanced by bringing the material back to the nest. Therefore, if it is not easy for the spider to bring the slaughtering material outside the nest back to the nest, even if the slaughtering material is placed in a place where the spider is likely to come out, the extermination effect is considered not so high.

  On the other hand, the poisoning bait for slaughter, when the slaughter ingredient is too thick, the scabbard may not eat and eat, so it is preferable to contain a considerable amount of dietary substance so that the sword will not be alert, The volume is inevitably bulky. Also, depending on the type of slaughtering ingredient, there will be no effect unless the moth is allowed to eat for several days. In this case, it is necessary to secure a predetermined amount or more of the killing poison bait accommodated in one bag so as to be eaten in several times. For these reasons, the size of the bag containing the poisoning bait for slaughtering is increased. However, since the doorway of the spider's nest is narrow, it is considered that it is not easy to put a bag body containing a predetermined amount or more of the poisoning bait for killing from the doorway of the spider's nest into the nest. In this regard, a technique for making it easier to put a bag containing a poisonous bait for killing into the nest of a nest has not been known.

  That is, in patent document 1, the action induction part which maintains the shape which protruded upwards at the time of installation of a rodenticide is comprised with the joining piece of a bag body, and this action inducer is made to hold it in a cage | basket and nest of a rodenticide However, even if a spear grabs the action-inducing part and pulls the killing material into the nest, the bag containing a predetermined amount or more of the poisoning bait for killing is large. As a result, the bag hits the nest doorway and cannot easily be retracted, and as a result, the bag may give up being pulled.

  Moreover, in patent document 2, although the eating rate of the poison bait | killing agent for slaughter is aimed at by widening the range of the non-seal part of a bag body, if it is not easy to bring a slaughter material to a nest, a result Therefore, it is considered that the eating rate is difficult to improve.

  Moreover, in patent documents 3-5, although it is disclosed about the material of a bag body, even if what the material of a bag body is, if the shape of a bag body is not the shape which is easy to enter from the doorway of a nest, a result Therefore, it is considered that the eating rate is difficult to improve.

  The present invention has been made in view of such a point, and the object of the present invention is to introduce a rodenticide containing a poisonous bait for killing a predetermined amount or more into a bag body from the nest entrance to the inside of the nest. The purpose is to increase the effect of removing cocoons by making it easier to put.

  In order to achieve the above object, according to the present invention, the bag is easily bent when the spider tries to put the rodenticide into the nest from the doorway of the nest.

  According to a first aspect of the present invention, there is provided a rodenticide comprising a poisonous bait for killing and a bag body containing the poisonous rodenticide for killing, wherein the bag body has a folding portion that allows the bag body to be folded. It is characterized by that.

  According to this configuration, for example, when a bag holds a bag body and tries to be pulled into the nest from the entrance of the nest, the bag body is easily bent starting from the bent portion, so that the bag body is longer than the size of the doorway, for example. Even so, it will enter the nest with a small force. Therefore, even if the slaughtering material is provided with a large bag that can store a predetermined amount or more of the slaughter poison bait, the scabbard can easily enter the nest from the nest entrance through the nest.

  According to a second aspect of the present invention, the bag body includes a first housing portion and a second housing portion that house the poisoning bait for killing, and the bent portion includes the first housing portion and the second housing portion. It is provided between the parts.

  According to this configuration, the bag body is bent by the bent portion between the first storage portion and the second storage portion in a state where the poisoning bait for killing is stored in the first storage portion and the second storage portion. Is possible.

  According to a third aspect of the present invention, the bag body has a long shape, the first storage portion and the second storage portion are provided so as to be aligned in the longitudinal direction of the bag body, and the bent portion is It is provided in the longitudinal direction intermediate part of a bag body, It is characterized by the above-mentioned.

  According to this configuration, when a predetermined amount or more of a poisoning bait for killing can be accommodated as a long-shaped bag body, the bag body bends at the middle portion in the longitudinal direction of the bag body, It becomes easy to enter inside.

  4th invention is comprised by the division part which divides the said bending part into the said 1st accommodating part and the said 2nd accommodating part, It is characterized by the above-mentioned.

  According to this structure, since the partition part of a bag is a part for partitioning a 1st accommodating part and a 2nd accommodating part, it becomes a part in which the poison bait for slaughter does not exist, and it becomes easy to bend. Therefore, by making the partition portion a bent portion, the bag body becomes compact and easily bends compared to the case where the bent portion is provided separately from the partition portion.

  According to a fifth aspect of the invention, the partition portion is formed by joining members constituting the bag body.

  According to this structure, since a partition part becomes thin, a bag body comes to bend still more easily. Moreover, since the thin part is formed in the bag body, the bag can easily hold the bag body.

  The sixth invention is characterized in that the bent portion is formed continuously from one end portion to the other end portion in a direction orthogonal to the longitudinal direction of the bag body.

  According to this configuration, the bent body is more easily bent by the continuous bent portion.

  The seventh invention is characterized in that the bent portion has a predetermined width in the longitudinal direction of the bag body.

  According to this configuration, since the bent portion has a predetermined width, the interval between the first storage portion and the second storage portion is ensured at a predetermined level or more. Therefore, when the bag body is folded, the first housing portion and the second housing portion are less likely to interfere with each other, and the folding angle of the bag body is increased.

  According to the first invention, since the bag body that stores the poisoning bait for killing has a bent portion, the rodenticide containing the poisoning bait for killing of a predetermined amount or more in the bag body, It can be made easier to enter the nest from the doorway. Thereby, it becomes easy to eat the poison bait for slaughter inside the spider web, and the extermination effect can be enhanced.

  According to the second invention, the bag body can be folded between the first housing portion and the second housing portion, and the length of the folded bag body can be sufficiently shortened.

  According to the third aspect of the present invention, it is possible to easily put the rodenticide into the nest when a bag of rodenticide is formed in a long shape and can accommodate a predetermined amount or more of the poisonous bait for killing.

  According to the fourth invention, since the partition portion for partitioning the first storage portion and the second storage portion is the folding portion, the bag body can be made compact and can be easily bent. Can do.

  According to the fifth invention, since the partition portion is formed by joining the members constituting the bag body, the bag body can be more easily bent and the bag body can be easily wrinkled. it can.

  According to the sixth aspect, since the bent portion is continuous from one end portion to the other end portion in the direction orthogonal to the longitudinal direction of the bag body, the bag body can be bent more easily.

  According to the seventh invention, since the folded portion has a predetermined width in the longitudinal direction of the bag body, the first housing portion and the second housing portion interfere with each other when the bag body is folded. It becomes difficult to increase the folding angle of the bag.

It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

(Embodiment 1)
FIG. 1 is a plan view of a rodenticide 1 according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG. As shown in FIG. 2, the rodenticide 1 includes a rodentic bait 20 for killing and a bag body 10 that houses the rodentic bait 20 for rodenting, and is placed outside the spider web. It is for exterminating the spider by letting the spider eat the poisonous bait for killing inside the nest. The rodenticide 1 can also be called a rodenticide or a rodenticide. The rodenticide 1 can be placed in the vicinity of the nest hole, which is the doorway of the nest, or can be placed away from the doorway of the nest. It is preferable to place it in the vicinity of the entrance of the place or nest.

(Poison bait for killing 20)
The poisoning bait for slaughter 20 is formed into an arbitrary shape such as a granular shape, a tablet shape, a tablet shape, a pellet shape, or a block shape, and includes a slaughtering ingredient and a dietary substance. Examples of the slaughter component include coumarin compounds such as warfarin, coumatetralyl, coumarin, indandion compounds such as chlorofacinone, diphacinone, pindon, and valone. Examples thereof include triaryl-substituted coumarin compounds such as fetialol, diphenacone, brodifacon, bromadiolone and furocumaphen, and compounds such as sililoside, boric acid, fipronil and hydramethylnon.

  As a slaughtering ingredient, it can be used by mixing only one kind or two or more kinds of the above compounds. Content of the said compound should just be a grade which can exhibit the killing effect, and can be made into conventionally well-known content.

  Regardless of processed, artificial or natural dietary substances, corn, potato, sweet potato starch, starch hydrolyzate, wheat flour, rice flour, soybean flour, peanut flour, sesame flour, vegetable flour, bran, plant Examples of the moving substance include pupa, fish meal, milk, animal protein, feed yeast, various amino acids, and the like. Examples of carbohydrates include fructose, glucose, brown sugar, red sugar, tri-warm sugar, granulated sugar, bee honey, and sugarcane juice. Examples of lipids include various vegetable oils and various animal oils such as sesame oil, nutka oil, coconut oil, corn oil, peanut oil, butter, egg oil, and whale oil. The above dietary substances can be freely and arbitrarily mixed and blended.

  The bait killing bait 20 is further processed, artificial or natural, as required, attracting substances, feeding promoting substances, water retention agents, preservatives (including bactericidal and antifungal), antioxidants, bulking agents. It is also possible to contain various additives such as anti-fouling agents, preservatives, fragrances, and pigments according to the taste of the target animal, and there are no particular limitations on the composition, selection, and mixing thereof.

  For example, about 3 g to 8 g of slaughter poison bait 20 is accommodated in one bag body 10, and in this embodiment, 5 g of slaughter poison bait 20 is accommodated. If the slaughtering ingredient contained in the poisoning bait 20 for slaughter is to exert its extermination effect by being eaten in several days, eat it in one day so that you do not eat everything in one day A larger amount of slaughter poison bait 20 than can be accommodated in one bag 10. It is also possible to store a larger amount of the poisonous bait for killing 20 than the amount that a single spider should eat in a single bag body 10. It can be exterminated by the rodenticide 1. The amount of the killing poison bait 20 accommodated in one bag 10 can be arbitrarily set according to the kind and content of the killing ingredient, the kind and content of the dietary substance, and the like. Further, the amount of the slaughter poison bait 20 accommodated in one bag 10 may be determined by the weight or by the volume. Here, the “predetermined amount or more” means, for example, the amount that one adult rat can not eat all in one day, for example, the amount that two or more animals (two to three) cannot eat all in one day It can also be. The reference moth can be an adult black rat (male or female), but is not limited to this. The “predetermined amount” can be obtained by a test or the like.

(Bag 10)
The bag body 10 is made of a member having air permeability and capable of tearing or tearing the heel with teeth or nails, and examples thereof include nonwoven fabric, paper, and woven fabric. . Examples of the fibers constituting the nonwoven fabric include resin fibers such as polypropylene (PP) and polyethylene terephthalate (PET). The nonwoven fabric may be made of resin fibers and paper. The member constituting the bag body 10 can be a member that can be thermally welded. The air permeability of the bag body 10 may be such that the attracting substance released from the poisoning bait 20 contained inside can be released to the outside of the bag body 10.

  The bag body 10 has a long shape. The bag body 10 is provided with a first housing portion 11 and a second housing portion bag body 12 for housing the killing poison bait 20 so as to be arranged in the longitudinal direction of the bag body 10. Between the 2nd accommodating part 12, the bending part 13 which makes the said bag body 10 bendable is provided. Since the bent portion 13 is provided between the first storage portion 11 and the second storage portion 12, it is provided at an intermediate portion in the longitudinal direction of the bag body 10.

  The size (length) in the longitudinal direction (left-right direction in FIG. 1) of the bag body 10 is set to be longer than the minimum diameter of the entrance / exit of a nest inhabiting a common adult rat. Although the details of the minimum diameter of the entrance of the nest inhabited by adult common black rat animals will be described later, it is, for example, about 25 mm to 30 mm. In this embodiment, the dimension of the longitudinal direction of the bag body 10 can be set in the range of 70 mm or more and 150 mm or less, for example. If the size of the bag body 10 in the longitudinal direction is shorter than 70 mm, the amount of the bait killing bait 20 that can be accommodated in one bag body 10 is reduced. In order to accommodate a predetermined amount of the bait killing bait 20 after making the length of the bag body 10 shorter than 70 mm, the size of the bag body 10 in the direction perpendicular to the longitudinal direction (B shown in FIG. ) Becomes longer, and it becomes difficult to put the rodenticide 1 into the nest from the entrance of the nest, and as a result, the eating rate of the poisonous bait for rodent 20 may be reduced. The length of the bag body 10 is more preferably set in the range of 90 mm to 120 mm.

  On the other hand, when the dimension of the longitudinal direction of the bag body 10 is longer than 150 mm, the dimension B of the bag body 10 can be shortened, but it becomes difficult for the spider to carry the rodenticide 1. Furthermore, the rodenticide 1 becomes difficult to enter the nest, and as a result, the eating rate of the rodenticide for bait 20 may be reduced.

  The dimension B of the bag body 10 can be set in the range of 20 mm or more and 30 mm or less. If the size B of the bag body 10 is shorter than 20 mm, the amount of the bait killing bait 20 that can be accommodated in one bag body 10 is reduced, and the size B of the bag body 10 is made shorter than 20 mm. In order to accommodate a predetermined amount of poisoning bait 20 for slaughter, the length of the bag body 10 becomes long, and it becomes difficult for the sword to carry the slaughter material 1 and to prevent the slaughter material 1 from entering the nest. As a result, the eating rate of the poisoning bait 20 for slaughter may be reduced. If the size B of the bag 10 is longer than 30 mm, it will be close to or exceeding the minimum diameter of the nest entrance where general adult adult rats live, and the rodenticide 1 will be removed from the nest entrance to the nest. It becomes difficult to put inside, and as a result, the eating rate of the slaughter poison 20 may be reduced.

  In this embodiment, the capacity | capacitance of the 1st accommodating part 11 and the 2nd accommodating part 12 is made substantially the same, and the quantity of the half of the total amount of the poisoning bait 20 accommodated in one bag 10 is 1st accommodation. The remaining half of the amount is accommodated in the second accommodating portion 12. Therefore, the length C of the 1st accommodating part 11 and the length D of the 2nd accommodating part are set substantially equal. The dimensions C and D can be set in the range of 30 mm to 70 mm, for example, and preferably 40 mm to 60 mm. The thickness (the vertical dimension in FIG. 2) of the first storage part 11 and the second storage part 12 in the state where the poisoning bait 20 for slaughter is stored can be shorter than the dimension B, for example, 5 mm or more. It can be set within a range of 20 mm or less. As for the thickness of the 1st accommodating part 11 and the 2nd accommodating part 12, 8 mm or more and 12 mm or less are more preferable.

  The bent portion 13 of the bag body 10 is configured by a partition portion that partitions the first storage portion 11 and the second storage portion 12. The partition portion is a portion formed by joining members constituting the bag body 10 and has a thin plate shape as compared with the first storage portion 11 and the second storage portion 12. That is, the members constituting the bag body 10 are welded and joined in the thickness direction of the bag body 10 at the intermediate portion in the longitudinal direction of the bag body 10. Thereby, while the edge part by the side of the 2nd accommodating part 12 in the 1st accommodating part 11 is obstruct | occluded, the edge part by the side of the 1st accommodating part 11 in the 2nd accommodating part 12 is obstruct | occluded. Communication with the second housing portion 12 is blocked. Therefore, it can be said that the bent portion 13 is formed of a seal portion, and the venom for poisoning 20 does not exist in the bent portion 13. The bent portion 13 can also be said to be a plate-shaped portion (plate-shaped portion) that is thinner than the first housing portion 11 and the second housing portion 12.

  The bending portion 13 is a portion that is bent first when a bending force is applied to the rodenticide 1, and can also be referred to as a bending start portion. In this embodiment, since the poisoning bait 20 for slaughter is accommodated in the 1st accommodating part 11 and the 2nd accommodating part 12, respectively, when a bending force is made to act on the rodenticide 1, the 1st accommodating part 11 and the 2nd accommodating part 12 become difficult to bend. On the other hand, since the bent portion 13 is a partition portion, there is no poisonous bait for killing 20 inside, and it is a thin plate shape. Therefore, when a bending force is applied, the first storage portion 11 and the second storage portion. This part is easier to bend than 12 and can be bent with less force.

  Since the bent part 13 is located between the first accommodating part 11 and the second accommodating part 12, the bent part 13 is bent so that the first accommodating part 11 and the second accommodating part 12 overlap. Thereby, the dimension of the length direction of the rodenticide 1 becomes short compared with before bending, and becomes about a half.

  The bent portion 13 is formed continuously from one end to the other end in the direction (width direction) orthogonal to the longitudinal direction of the bag body 10. Thereby, the bending part 13 can be bent with a smaller force.

  Further, the bent portion 13 has a predetermined width in the longitudinal direction of the bag body 10. Specifically, as shown in FIG. 1, the width E of the bent portion 13 can be set in a range of 5 mm to 20 mm, and more preferably set in a range of 8 mm to 15 mm. By securing the width of the bent portion 13 to a predetermined value or more, when the bent portion 13 is bent, the first accommodating portion 11 and the second accommodating portion 12 are less likely to interfere with each other, and the folding angle of the bag body 10 is increased. can do.

(Modification)
3 and 4 show the rodenticide 1 according to the first modification of the first embodiment. In the first modification, a first seal portion 14 and a second seal portion 15 are provided at both longitudinal ends of the bag body 10. The first seal portion 14 and the second seal portion 15 are portions for closing the end portion of the bag body 10, and are formed by thermally welding members constituting the bag body 10 in the same manner as the bent portion 13. ing. Since the 1st seal part 14 and the 2nd seal part 15 become thin plate shape, when a spear carries the rodenticide 1, for example, the 1st seal part 14 and the 2nd seal part 15 can be held. One or both of the first seal part 14 and the second seal part 15 may be omitted.

  FIG. 5 shows a rodenticide 1 according to the second modification of the first embodiment. In the second modification, the bent portion 13 is deviated from the central portion in the longitudinal direction of the bag body 10 to one side in the longitudinal direction, and the first housing portion 11 is smaller than the second housing portion 12. As described above, the bent portion 13 can be displaced not only in the central portion in the longitudinal direction of the bag body 10 but also on one side. In the second modification, the first seal part 14 and the second seal part 15 of the first modification are provided. However, the present invention is not limited to this, and one or both of the first seal part 14 and the second seal part 15 are omitted. You can also.

  In addition, the bending part 13 should just bend more easily than the 1st accommodating part 11 and the 2nd accommodating part 12, and does not need to be the seal part by welding. Moreover, the 1st accommodating part 11 and the 2nd accommodating part 12 do not need to be completely interrupted | blocked by the bending part 13, and may communicate to some extent. Moreover, although the bending part 13 of the said embodiment and modification is one place, you may make it the rodenticide 1 bend | fold at two or more places.

(test)
Next, the test of the rodenticide 1 according to Embodiment 1 will be described. First, the test cage used for the test will be described with reference to FIGS. 6 and 7. The test cage 100 is composed of a lattice-like member, and has a rectangular shape in plan view shown in FIG. The dimension W in the short side direction of the test cage 100 is 23 cm. A partition plate 101 shown in FIG. 7 is provided inside the test cage 100, and the interior of the test cage 100 is partitioned into a nest 103 and a food storage place 104 by the partition plate 101. A water bottle 102 is placed in the nest 103. The dimension L1 of the bait storage area 104 shown in FIG. 6 is 38 cm, and the dimension L2 of the nest 103 is 8 cm. The height of the partition plate 101 shown in FIG. 7 is 17 cm so that the test animal cannot exceed the partition plate 101. This test cage 100 is a cage that keeps adult rats (female) of a rat, which is a test animal. The nest 103 was dimmed by sticking a plate on the back side of the partition plate 103, that is, around the nest 103, and by placing the water bottle 102, the test animal was easily settled. The test animals are black rats with a total length of about 25 cm and a body weight of about 120 g.

  As shown in FIG. 7, an entrance / exit 101 a is formed in the lower part of the partition plate 101. This doorway 101a is provided as a burrow opening. The height H1 of the doorway 101a was 3 cm, and the width W1 was 3 cm. The size of the doorway 101a was determined as follows.

  First, an entrance / exit confirmation test instrument shown in FIG. 8 is prepared. The entrance / exit confirmation testing instrument includes a first tubular member 301, a second tubular member 302, a passage forming member 303, and an entrance / exit forming plate (partition plate) 304. FIG. 8 is a plan view of the test device for doorway confirmation. The first tubular member 301 and the second tubular member 302 are arranged so as to extend in the vertical direction and are spaced from each other so that the passage forming member 303 is interposed therebetween. The diameters of the first cylindrical member 301 and the second cylindrical member 302 are 12 cm. The length of the passage forming member 303 is 25 cm. A passage 303 a extending in the horizontal direction is formed inside the passage forming member 303. One end of the passage 303 a communicates with the inside of the first tubular member 301, and the other end is the second tubular member 302. It communicates with the inside. The passage 303a is a passage having a circular cross section with a diameter of 4.0 cm.

  The entrance / exit forming plate 304 is disposed in the middle portion of the passage forming member 303 so as to extend in the vertical direction. As shown in FIG. 9, an opening 304 a is formed in the entrance / exit forming plate 304. This opening 304a is a part that becomes an entrance / exit. As shown on the left side of FIG. 9, an entrance / exit forming plate 304 having a square opening 304a and an entrance / exit forming plate 304 having a circular opening 304a as shown on the right side of FIG. 9 were prepared. For the entrance / exit forming plate 304 having a square opening 304a, the height H1 is 2.5 cm and the width W1 is 2.5 cm, and the height H1 is 2.0 cm and the width W1 is 2.0 cm. Prepared. For the entrance / exit forming plate 304 having a circular opening 304a, one having a diameter A of 3.0 cm and one having a diameter A of 2.5 cm were prepared.

  An adult rat (female) as a test animal was placed in the first cylindrical member 301, and it was observed whether or not this test animal could move to the second cylindrical member 302 through the passage 303a. When the entrance / exit forming plate 304 having a square opening 304a was attached, the test animal could pass when the height H1 was 2.5 cm and the width W1 was 2.5 cm, but the height H1 was 2.0 cm. When the width W1 was 2.0 cm, the test animal could not pass. In addition, when the entrance / exit forming plate 304 having a circular opening 304a was attached, the test animal could pass if the diameter A was 3.0 cm, but if the diameter A was 2.5 cm, the test animal could pass. I could not pass. Based on this result, the size of the entrance / exit 101a of the partition plate 101 of the test cage 100 shown in FIG. 6 is 3 cm in height H1 and 3 cm in width W1 so that it does not pose a problem for adult black rats (female) to pass through. I decided. This is because the size of the burrows made by adult rats is likely to be this level even in the actual environment.

  In the evening of the test day, two rodenticides 1 were placed in the feeding place 104 of the test cage 100 shown in FIG. However, in order to protect the test animals, the rodenticide 1 contained a bait excluding the rodenticide component. The video was taken for 12 hours until the morning of the next day, and it was confirmed from which part of the bag 10 of the rodent 1 that the test animal carried and carried by watching the video. Three test animals (one adult rat mouse and two adult male rats) were prepared and subjected to the same test. All three have a total length of about 25 cm and a body weight of about 120 g.

  The total number of times the sacrificial material 1 was picked up and moved was 38 times. Among them, the ratio of holding the bent portion 13 was about 80%, and the ratio of holding both ends (the first seal portion 14 or the second seal portion 15) was about 5%. That is, it can be seen that the ratio of holding the bent portion 13 of the rodenticide 1 is extremely high. The reason for this is unclear, but it is thought that the vicinity of the center of gravity is about to be held in order to carry the rodenticide 1 stably. Furthermore, since the bent portion 13 of the rodenticide 1 of the present embodiment is a thin plate, it is considered that the bent portion 13 can be easily held.

  FIG. 10 shows how the force required to draw the rodenticide 1 in the bait storage area 104 from the doorway 101a into the nest 103 is measured. As described above, since the rate of gripping the bent portion 13 of the rodenticide 1 is extremely high, the bent portion 13 of the rodenticide 1 is sandwiched between the clips 200 as shown in FIG. One end of the string 201 was attached. The other end of the string 201 was connected to the push-pull gauge 203. As the push-pull gauge 203, Max Capacity 30kg Readability 0.25kg Model S manufactured by KOMURA was used.

  The size of the entrance / exit 101a was 2.5 cm in height H1 and 2.5 cm in width W1. Further, as an example, the rodenticide 1 having the above-described configuration was prepared, and the rodenticide 1 had a length of 130 mm and a width B of 20 mm. Further, as a comparative example, a rodenticide having no bent portion 13 was prepared, and the rodenticide had a length of 130 mm and a width B of 20 mm. In the case of the embodiment, when the rodenticide 1 in the bait storage area 104 is drawn into the nest 103 from the doorway 101a, the bent portion 13 is easily bent, so that the indicated value of the push-pull gauge 203 is 0 on average of three times. It was a small value of 3 kg. On the other hand, since the rodenticide of the comparative example does not have the bent portion 13, the indicated value of the push-pull gauge 203 is 0.54 kg on average of three times, which is a value nearly twice that of the example. In this way, by providing the folding part 13 on the rodenticide 1, the force required to pull the rodenticide 1 into the nest 103 can be greatly reduced.

  Next, the actual movement of the test animal in the test cage 100 will be described with reference to FIGS. FIG. 11 to FIG. 16 are drawings based on video images of test animals in the test cage 100. FIG. 11 shows a state in which the test animal picks up and raises the rodenticide 1 in the bait storage area 104. As shown in this figure, the test animal holds the vicinity of the central portion of the rodenticide 1 in the longitudinal direction, that is, the vicinity of the bent portion 13. Thereafter, as shown in FIGS. 12 and 13, when the test animal carries the rodenticide 1 to the vicinity of the doorway 101a, the test animal once moves away from the doorway 101a, and then from the head to the doorway 101a as shown in FIG. Enter. After entering the nest 103 from the doorway 101a, the test animal changes its direction, and as shown in FIG. 15, the head is put out from the doorway 101a to the food storage area 104 and holds the vicinity of the bent portion 13 of the rodenticide 1. As shown in FIG. 16, the test animal moves backward as it is.

  At this time, since the vicinity of the bent portion 13 of the rodenticide 1 is pulled toward the inside of the nest 103, both longitudinal sides of the rodenticide 1 are the edges of the doorway 101a as shown in FIGS. The bending force acts on the rodenticide 1 by rubbing. Then, since the bent portion 13 of the rodenticide 1 is bent, the rodenticide 1 enters the nest 103 with a small force.

  In the case of the rodenticide 1 having the bent portion 13, the rodenticide 1 in the bait storage area 104 is brought back into the nest 103 from the doorway 101 a as shown in FIGS. 11 to 16. The time required to reach the state shown in FIGS. 11 to 16 was about 5 seconds (average of 2 times).

  On the other hand, in the case of the comparative example having no bent portion, even if the slaughtering material has the same size and the same weight, the time required to bring the slaughtering material 1 in the bait storage area 104 from the doorway 101a into the nest 103 is as follows. It was about 1 minute 25 seconds. This is because the length of the rodenticide is longer than the dimension of the doorway 101a, so that the rodenticide interferes with the edge of the doorway 101a.

(Effect of embodiment)
As described above, according to the rodenticide 1 according to this embodiment, when a spear tries to be drawn into the nest 103 from the doorway 101a of the nest 103 in the vicinity of the bent portion 13 of the bag body 10, Since the body 10 is easily bent starting from the bent portion 13, even if the bag body 10 is longer than the size of the doorway 101 a, the bag 10 can enter the nest 103 with a small force.

  As described above, in most cases, the scissors can grip the vicinity of the bent portion 13, but the scissors can sometimes grip the end of the rodenticide 1. In this regard, as described above, the size B of the bag body 10 is equal to or smaller than the width W1 of the doorway 101a. For this reason, when the spider grips the end of the rodenticide 1, it can be put into the nest 103 without being caught by the doorway 101 a if it is pulled as it is.

  In other words, the rodenticide 1 according to this embodiment has a shape that can be easily put into the nest 103 regardless of the position where the rod can be picked. Therefore, even in the rodenticide 1 having the large bag body 10 capable of accommodating a predetermined amount or more of the rodenticide 20 for rodent killing, the rod enters the nest 103 from the entrance / exit 101a of the nest 103 by its own power. It becomes easy. Therefore, the effect of removing the soot can be enhanced.

(Embodiment 2)
FIG. 19 shows a rodenticide 1 according to Embodiment 2 of the present invention. In Embodiment 2, the first seal portion 14 and the second seal portion 15 are provided, and the extending direction of the bent portion 13 and the first seal portion 14 and the second seal portion 15 is different. Since the other parts are the same as those of the first embodiment, the same parts as those of the first embodiment are denoted by the same reference numerals and the description thereof will be omitted, and different parts will be described. .

  That is, in the second embodiment, the first seal portion 14 and the second seal portion 15 are provided at both longitudinal ends of the bag body 10 as in the first modification of the first embodiment. The direction in which the first seal portion 14 and the second seal portion 15 extend and the direction in which the bent portion 13 extends intersect each other. Specifically, the first seal portion 14 and the second seal portion 15 extend. The direction and the direction in which the bent portion 13 extends are substantially orthogonal.

  In the second embodiment, the same effects as those of the first embodiment can be obtained.

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  In addition, the rodenticide 1 according to the present invention is also effective against rods other than the rat.

  As described above, the rodenticide according to the present invention can be applied to extermination of, for example, a rat.
