Description

  The present invention relates to a small animal capture device for capturing small animals, and more particularly to a capture device for capturing spiders.

  For example, a configuration disclosed in Patent Document 1 is known as a capture device for capturing small animals such as pupae and weasels. In this small animal trap, an adhesive surface 2 is formed on the central inner wall of the cylindrical body 1, and no adhesive surface is formed on the open end of the cylindrical body 1, that is, the inner walls near both inlets. Usually, since a small animal has a vigilance in entering a cylinder, if there is an adhesive surface near the entrance of the cylinder, the vigilance is increased and the capture rate is lowered. On the other hand, according to the above-described configuration, since the adhesive surface is not formed on the inner wall surface in the vicinity of both the inlets of the cylindrical body 1, the alertness to the cylindrical body 1 is released and a small animal is guided to the adhesive surface 2. be able to.

Utility Model Registration No. 3095280

  However, even with small animal traps such as those described above, small animals, especially moths, have a stronger force on the hind legs than on the front legs, so when the front legs touch the adhesive surface and feel uncomfortable, There was a problem that the hind legs that were not attached to the surface were used for rearing and eventually the front legs were pulled away from the adhesive surface and escaped from the small animal trap. Then, this invention makes it a subject to provide the small animal trap which can capture small animals, such as a spider, reliably.

  A first small animal capturing device according to the present invention is a capturing device for capturing small animals such as pupae and weasels, and has a bottom surface and a side surface extending from the bottom surface, and an entrance for the small animal is formed. A first adhesive surface formed by interposing a non-adhesive surface between the main body and the bottom surface with the intrusion opening; and at least a part of the side surface corresponding to the non-adhesive surface. And a second adhesive surface.

  According to this small animal trap, since the non-adhesive surface is interposed between the first adhesive surface formed on the bottom surface and the entrance, the small animal is guided to the first adhesive surface inside the trap. The When the forefoot sticks to the first adhesive surface, the small animal usually moves back in the trapping device while using the hind legs to pull the front foot away from the first adhesive surface. Here, since the second adhesive surface is formed on the side of the non-adhesive surface, that is, the portion corresponding to the non-adhesive surface on the side surface, the hind legs and body of the small animal adhere to the second adhesive surface. It is possible to reliably prevent a small animal from escaping from the trap.

  The small animal trap can take various configurations. For example, when the small animal is ramped to move backward from the trap as described above, the second adhesive surface is surely brought into contact with the small animal. The side surface can swing with respect to the bottom surface.

  Moreover, the 2nd adhesion surface is formed in the side surface, and it can also be set as the structure extended to the entrance port side rather than the 1st adhesion surface.

  The second small animal trap according to the present invention is a sheet-like main body that can be bent into a cylindrical shape having at least one end opened, and has a bottom surface and a side surface that is foldably connected to the bottom surface. A first adhesive surface formed by interposing a non-adhesive surface between at least one end of the main body and the bottom surface; and at least a part of the side surface corresponding to the non-adhesive surface And a formed second adhesive surface.

  According to this small animal trap, the main body can be bent and formed into a cylindrical shape. And what was formed in the cylinder shape can prevent reliably that a small animal escapes from a trap similarly to the 1st small animal trap mentioned above.

  According to the small animal trap according to the present invention, small animals such as pupae can be reliably captured.

  Hereinafter, an embodiment of a small animal trap according to the present invention will be described with reference to the drawings. In the following description, a small animal is used as an example. Moreover, the dashed-dotted line in the figure has shown the bending line.

  As shown in FIG. 1, the small animal trap 1 mainly includes a main body 2 and a first adhesive surface 3 and a second adhesive surface 4 formed on the inner wall of the main body 2.

  The main body 2 includes a bottom surface 21, side surfaces 22 a and 22 b extending upward from the bottom surface 21, and a top surface 23 positioned above the bottom surface 21, and is configured as a cylindrical body having both ends in the length direction opened. ing. And this opened part becomes the intrusion opening 24 of the bag. The main body 2 is assembled as shown in FIG. 1 when in use, but is folded as shown in FIG. 2 when not in use such as during sales or storage.

  FIG. 3 is a development view of the small animal trap 1. As shown in FIG. 3, the main body 2 is composed of a single sheet, and is divided into four parts in the order of the side surface 22 a, the bottom surface 21, the side surface 22 b, and the top surface 23 from the left in FIG. 3. A bend line that can be valley-folded is formed at the boundary between the bottom surface 21 and the side surfaces 22a and 22b and the boundary between the side surface 22b and the top surface 23, and an engagement piece 221 is formed on the side surface 22a located at the left end. An engagement hole 231 into which the engagement piece 221 can be inserted is provided on the upper surface 23 provided at the right end. For this reason, the main body 2 becomes a cylindrical body as shown in FIG. 1 and can maintain its state by bending along the folding lines and inserting the engaging protrusions 221 into the engaging holes 231.

  Further, bent pieces 25 are formed at both end portions of the bottom surface 21, the side surfaces 22 a and 22 b, and the top surface 23 on the side of each entry port 24. Thus, the following effects can be acquired by forming the bending piece 25. FIG. That is, the small animal trap 1 is in a folded state as shown in FIG. 2 when not in use, but when the folded pieces 25 are in contact with each other in this state, the adhesive surfaces described later are It is possible to prevent contact. Each bent piece 25 is always bent inward as shown in FIG.

  Furthermore, a spacer 26 is installed at the center in the length direction of the bottom surface 21 and the center in the length direction of the side surface 22b. The spacer 26 preferably has a thickness of about 2 to 10 mm. By installing the spacer 26 in this way, when the side surface 22a is bent so as to overlap the bottom surface 21 as shown in FIG. 5, the portion of the side surface 22a where the adhesive surface is not formed comes into contact with the spacer 26. It can prevent that surfaces contact. Similarly, when the upper surface 23 is bent so as to overlap the side surface 22b, the portion of the upper surface 23 where the adhesive surface is not formed contacts the spacer 26, and the adhesive surfaces can be prevented from contacting each other.

  The material of the main body 2 is not particularly limited, and examples thereof include water-resistant paper and paper such as coated cardboard, plastic such as polypropylene, wood, and metal. The size of the main body 2 is not particularly limited. For example, in the case of a rat, the length is 15 to 30 cm, the width of the entrance 24 is 6 to 12 cm, and the height of the entrance 24 is set. It is preferably 6 to 18 cm.

  As shown in FIG. 3, the first adhesive surface 3 is formed by applying an adhesive to the bottom surface 21 of the main body 2. The first adhesive surface 3 is formed at the center in the length direction of the bottom surface 21, the first adhesive surface 3 is not formed in the vicinity of each intrusion port 24, and a non-adhesive surface 5 is formed instead. Has been. The non-adhesive surface 5 may be formed by sticking a non-adhesive material (for example, non-woven fabric, cellophane) on the first adhesive surface 3, or by not applying an adhesive to this part in the first place. It may be formed. The length of the first adhesive surface 3 is preferably about 13 to 28 cm, and the length of the non-adhesive surface 5 is preferably about 1 to 10 cm, and further about 4 to 7 cm. More preferably.

  Similar to the first adhesive surface 3, the second adhesive surface 4 is formed by applying an adhesive to the side surfaces 22a and 22b. The second adhesive surface 4 is formed in a state that is longer than the first adhesive surface 3 in the length direction, that is, extends longer to the intrusion port 24 side than the first adhesive surface 3. For this reason, in each side surface 22a, 22b, the 2nd adhesion surface 4 is formed also in the part corresponding to the non-adhesion surface 5. FIG. In addition, the part enclosed with the broken line of FIG. 3 is "the part corresponding to the non-adhesive surface 5" in each side surface 22a, 22b. In order to prevent backlash, the length of the pressure-sensitive adhesive at the portion corresponding to the non-adhesive surface 5 on each of the side surfaces 22a and 22b is preferably about 1 to 10 cm, and more preferably about 4 to 7 cm. .

  The third adhesive surface 6 is formed by applying an adhesive to the upper surface 23 in the same manner as the first and second adhesive surfaces 3 and 4. The third adhesive surface 6 has the same length as the second adhesive surface 4, and is formed in a state of extending longer to the respective entrances 24 than the first adhesive surface 3. For this reason, on the upper surface 23, the third adhesive surface 6 is also formed at a portion corresponding to the non-adhesive surface 5.

  Although it does not specifically limit as an adhesive which forms each adhesive surface 3,4,6 mentioned above, For example, a rubber adhesive, an acrylic adhesive, a silicone adhesive, a urethane adhesive, etc. are illustrated. can do.

  Next, a method for capturing a pupa using the small animal trap 1 described above will be described.

  First, the small animal trap 1 when not in use will be described. The small animal trap 1 when not in use maintains the folded state shown in FIG. In this folded state, the side surface 22a and the upper surface 23 are valley-folded inward along the folding line from the expanded state shown in FIG. 4 to the state shown in FIG. In this state, each spacer 26 is in contact with a portion of the side surface 22a where the second adhesive surface 4 is not formed and a portion of the upper surface 23 where the third adhesive surface 6 is not formed, and a bent piece. Since the 25 are in contact with each other, the adhesive surfaces are not in contact with each other. Then, the valley is folded along the middle folding line from the state shown in FIG. 5, and a folded state as shown in FIG. 2 is obtained. In this state, each of the adhesive surfaces 3, 4, 6 faces inward and is protected from the outside.

  Next, the small animal trap 1 in use will be described. The small animal trap 1 in the folded state described above is in an expanded state shown in FIG. Then, the side surfaces 22a and 22b are bent along the fold line with respect to the bottom surface 21 (FIG. 6), the upper surface 23 is bent with respect to the side surface 22b, and the engagement pieces 221 formed on the side surface 22a are formed on the upper surface 23. It is inserted into the formed engagement hole 231 and completed (FIG. 1).

  The small animal trap 1 assembled in this way is installed in a place (eg, kitchen, attic, barn, plastic house, etc.) where a shark is likely to appear. In order to attract cocoons, it is preferable to arrange an attractant such as sunflower seeds, kinako or sesame in the trap 1.

  The attractant in the small animal trap 1 and the kite attracted by the darkness inside the trap enter the trap 1 through the intrusion port 24 with caution. Since the non-adhesive surface 5 is formed in the vicinity of the intrusion port 24 on the bottom surface 21, the heel advances to the inside of the trap 1 as it is, and most of the body enters the trap 1. When the heel further advances inside the trap 1, the forefoot adheres to the first adhesive surface 3. When the forefoot sticks to the first adhesive surface 3 in this manner, the heel begins to rampage to strengthen the vigilance and pull the front foot away from the first adhesive surface 3. At this time, the wrinkles are placed on the non-adhesive surface 5, but the second adhesive surface 4 is formed on the side of the non-adhesive surface 5, that is, on the side surfaces 22a and 22b corresponding to the non-adhesive surface 5. For this reason, the body of the heel, particularly the back foot, contacts the second adhesive surface 4. As a result, the samurai is deprived of body freedom and cannot escape from the trap 1. In addition, when a wrinkle rampages, the shape of the trap 1 may collapse and the third adhesive surface 6 and the like on the upper surface 23 may stick to the wrinkle. Thus, the small animal trap 1 according to the present embodiment can reliably capture the pupae.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these, A various change is possible unless it deviates from the meaning of this invention.

  For example, in the above-described embodiment, the main body 2 is configured as an assembly type, but is not particularly limited to this, and is not limited thereto, that is, the main body 2 is formed in a cylindrical shape from the beginning. It can also be configured.

  In the above embodiment, the main body 2 has been described as a quadrangular prism. However, the shape of the main body 2 is not particularly limited. For example, the main body 2 may be formed in another polygonal column shape or a cylindrical shape. You can also. In addition, it may be a triangular prism shape, but it should be a quadrangular prism shape or a polygonal prism shape with four or more corners so that the side surfaces 22a and 22b of the main body 2 may fall down and easily come into contact with the spider when a small animal such as a spider is captured. Is preferred.

  Moreover, in this embodiment, since it aims at catching a wrinkle in the part corresponding to the non-adhesion surface 5 regarding the 2nd adhesion surface 4, as shown in FIG. 7, the 1st in each side surface 22a, 22b is shown. The second adhesive surface 4 may not be formed on the portion corresponding to the adhesive surface 3. Furthermore, if it says further, the 2nd adhesion surface 4 may be formed only in either one of the side surfaces 22a and 22b, and even if the 3rd adhesion surface 6 is not formed in the upper surface 23. Good.

  Moreover, in the said embodiment, although the adhesion surfaces 3, 4, and 6 are integrally formed over the side surface 22a of the main body 2, the bottom face 21, the side surface 22b, and the upper surface 23, the 1st adhesion surface 3, 2nd The adhesive surface 4 and the third adhesive surface 6 may be formed separately.

  Moreover, in the said embodiment, although the upper surface 23 was closed, this upper surface 23 can also be made into the open state. In the past, the structure was such that the wrinkles were caught by the adhesive surface formed on the bottom surface, so it was normal to keep the top surface closed in order to prevent dust and the like from adhering to weakening the adhesive force. It was. However, in this embodiment, since it is a structure which catches wrinkles mainly by the 2nd adhesion surface 4 formed in side surface 22a, 22b, even if it opens the upper surface 23, a problem will not arise in particular. Moreover, by opening the upper surface 23 in this way, there is an effect that it is possible to diminish the alertness of the bag.

  The present invention will be described more specifically with reference to the following examples and comparative examples. In addition, this invention is not limited to the following Example.

  As Examples 1 to 4, small animal traps 1 as shown in FIGS. 1 to 6 having different non-adhesive surfaces 5 were prepared. In addition, a non-woven fabric is installed as the non-adhesive surface 5, the length of the non-adhesive surface 5 of Example 1 is 4.0 cm, Example 2 is 5.0 cm, Example 3 is 7.0 cm, and Example 4 is 2 cm. .5 cm. Moreover, the small animal trap 10 which does not have the non-adhesive surface 5 as the comparative example 1, ie, the small animal trap 10 in which the 1st adhesive surface 3 is extended also in the part of the non-adhesive surface 5 was produced (refer FIG. 8). ). Furthermore, as Comparative Example 2, the non-adhesive surface 5 is formed not only on the bottom surface 21 but also on the side surfaces 22a and 22b and the upper surface 23, that is, the second adhesive surface is formed in a portion corresponding to the non-adhesive surface 5. A small animal trap 100 in which no 4 was formed was produced (see FIG. 9). The length of the non-adhesive surface 5 in Comparative Example 2 was 5.0 cm.

  The size of each small animal capture container 1,10,100 is the same, the length is 21.4 cm, the width of the bottom surface 21 is 8.2 cm, and the height of the lowest part of the entrance 24 is 7.4 cm. The lengths of the second and third adhesive surfaces 4 and 6 are 18.0 cm, and the length of the first adhesive surface 3 is a value obtained by subtracting the length of two non-adhesive surfaces 5 from 18.0 cm. It becomes. The material of the main body 2 is water-resistant paper, and a rubber-based adhesive mainly composed of polybutene was used as an adhesive for forming the first to third adhesive surfaces 3, 4, 6.

  Using the above five types of small animal traps, it is possible to prevent the rats that have entered the traps from moving backwards and escaping from the traps (prevention of backlashes). The experiment about whether or not it was captured (capture after 1 hour) was performed three times each (only Examples 3 and 4 were performed twice), and the results are shown in Table 1. In Table 1, “◯” in the item of “prevention of backlash” means that backlash can be prevented, and “x” means that it escapes back. In addition, “◯” in the item “capture after 1 hour” means that the rat was still captured after 1 hour, and “x” means that the rat had escaped from the trap after 1 hour.

  From the results of Table 1, in the small animal traps 1 of Examples 1 to 3, it is possible to more effectively prevent the sputs from moving back and escape from the traps than the traps 10 and 100 of Comparative Examples 1 and 2. Furthermore, it was found that even after one hour, the cocoons were reliably captured. None of them were able to run through. If the length of the non-adhesive surface 5 is 2.5 cm or more, it is possible to prevent the rat from slipping back. If the length of the non-adhesive surface 5 is 4.0 cm or more, it is sure even after 1 hour. I found out that I can capture cocoons. In addition, the photograph which shows a mode that the rat in the trap of the comparative example 1 escaped backwards was shown in FIG.
