Description

Technical Field

[0001] The present invention relates to a millipede bait agent container for containing a bait agent.

Background Art

[0002] Millipedes are unpleasant pests with many legs on an elongated body including centipedes, flat-backed millipedes, wireworms, house centipedes, and caterpillar hunters. As a millipede bait agent container for feeding such millipedes with a bait agent to kill them, the one described in Patent Document 1 has been proposed. The centipede bait agent container of Patent Document 1 is provided with an inclined portion surrounding a bait agent accommodating recess for accommodating the bait agent, and the bait agent is accommodated so as not to exceed a virtual extension surface formed on an extension line of an inclination angle of the inclined portion. Thereby, centipedes are induced to the bait agent, making it easier to eat the bait agent.

[0003] However, the above-described conventional centipede bait agent container has a problem that since the surface of the inclined portion is smooth, it is difficult for millipedes to climb the inclined portion, and it is difficult for millipedes to enter the bait agent accommodating recess.

[0004] In addition, a container provided with irregularities along the horizontal direction on the inclined portion (Patent Documents 2 and 3) and a container provided with the inclined portion in a stepped shape have been proposed (Patent Documents 4 and 5). However, in Patent Documents 2 to 5, it cannot be said that the above problem has been sufficiently solved. To explain the reason, millipedes such as centipedes have claw-shaped legs. In the case of horizontal irregularities or steps like the containers of Patent Documents 2 to 5, the claw-shaped legs of millipedes can only fix the insect body in the inclined direction and allow slipping in the horizontal direction. For this reason, there is a risk that millipedes will slip along the horizontal irregularities or steps and cannot enter the bait agent accommodating recess.

Embodiments for Carrying Out the Invention

[0013] Specific embodiments of the present invention will be described below with reference to the respective drawings.

[0014] The millipede poison bait container 1 according to the present embodiment has, as shown in FIGS. 1 to 3, a container body 2 and a roof body 3 that covers the container body 2. As shown in FIGS. 2 and 3, the container body 2 has a poison bait accommodating recess 4 in which a poison bait 100 (FIG. 7) serving as bait is accommodated, and an inclined portion 5 that extends from the entire periphery of the poison bait accommodating recess 4 to the installation surface 101 on the outer peripheral side at a predetermined angle.

[0015] As shown in FIGS. 2 and 3, the container body 2 has an outer peripheral wall portion 7 and an inner peripheral wall portion 8 as a wall portion standing up around the bottom plate portion 6. In the present embodiment, the bottom plate portion 6 is formed in a quadrangular shape. In the illustrated example, it is rectangular as shown in FIG. 4. The outer peripheral wall portion 7 is continuous along each side of the bottom plate portion 6 to form a concave space in the central portion. This concave space becomes the poison bait accommodating recess 4. As shown in FIGS. 2 and 3, in the cross-sectional shape of the surface orthogonal to the extending direction of the outer peripheral wall portion 7, the outer side becomes a walking surface portion 71, and the inner side becomes a housing portion inner wall surface portion 72. A top flat surface 73 parallel to the bottom plate portion 6 is formed with a slight width between the walking surface portion 71 and the housing portion inner wall surface portion 72.

[0016] The inner peripheral wall portion 8 rises from the bottom plate portion 6 inside the outer peripheral wall portion 7. The inner peripheral wall portion 8 is provided lower than the outer peripheral wall portion 7. As shown in FIG. 4, the inner peripheral wall portion 8 is provided along the entire circumference of the bottom plate portion 6. As shown in FIG. 7, the bait agent 100 is accommodated in the range surrounded by the inner peripheral wall portion 8. In other words, the inner peripheral wall portion 8 surrounds the entire circumference of the accommodation range of the bait agent 100.

[0017] At the four corner portions of the outer peripheral wall portion 7, as shown in FIG. 2, the roof body support shafts 9 whose axes are perpendicular to the bottom plate portion 6 stand up. The roof body support shaft 9 has a tapered shaft 91 with a tapered tip at the standing tip. The upper end surface 92 of the roof body support shaft 9 is higher than the top flat surface 73.

[0018] As shown in FIG. 7, the bait agent 100 is accommodated in the bait agent accommodation recess 4. The bait agent 100 contains an attractant, an excipient, an anti-ingestion agent, a preservative, a pH adjuster, etc. The bait agent 100 is, for example, a gel-like solid. The bait agent 100 is arranged so as not to exceed the virtual extension surface S formed on the extension line of the inclination angle 60° of the inclined portion 5.

[0019] Also, a protective film (not shown) or the like that is peeled off during use can be pasted on the upper end surface of the bait agent. The protective film reduces damage to the bait agent 100 due to drying or contact with foreign matter before use. Of course, the bait agent 100 can be stored in a sealed bag and opened during use and accommodated in the bait agent accommodation recess 4 of the container body 2.

[0020] Also, on the bottom plate portion 6 that forms the bottom of the bait agent accommodation recess 4, as shown in FIGS. 2 to 4, a plurality of fixed walls 10 stand up in the radial direction centered on two points arranged in the longitudinal direction of the bottom plate portion 6. The fixed wall 10 is provided at the same height as the above-described inner peripheral wall portion 8. By being embedded in the bait agent 100, the fixed wall 10 can enhance the retention of the bait agent 100 with respect to the container body 2.

[0021] In the container body 2 according to this embodiment, a walking surface portion 71 extending from the entire periphery of the bait agent housing recess 4 to the installation surface 101 on the outer peripheral side is an inclined portion 5 having an upward slope from the installation surface 101 toward the bait agent 100, and a top flat surface 73 is formed at the top of the inclined portion 5. This top flat surface 73 serves as an adhesive margin when the above-described protective film is adhered to the container body 2, and its width is preferably 10 mm or less. If the width exceeds 10 mm, when the head of a myriapod such as a centipede reaches the top flat surface 73, its antennae will face horizontally, and there is a possibility that it will take evasive action. Of course, in this embodiment, the walking surface portion 71 has the top flat surface 73, but the top flat surface 73 may be omitted. Also, the height L of the walking surface portion 71 is preferably about 4 to 10 mm.

[0022] Further, a lattice-shaped rib 13 is provided on the inclined portion 5 of the container body 2. As shown in FIG. 4, the rib 13 is provided on all inclined portions 5 surrounding the entire periphery of the bait agent housing recess 14. As shown in FIG. 5, the lattice-shaped rib 13 projects from the inclined portion 5 and has a plurality of first convex portions 131 that are long in a first direction and a plurality of second convex portions 132 that intersect the first convex portions 131 and are long in a second direction.

[0023] The plurality of first convex portions 131 are arranged side by side at intervals in the horizontal direction. The plurality of second convex portions 132 are arranged side by side at intervals in the horizontal direction. The first and second convex portions 131 and 132 are provided so as to intersect at both ends and the center thereof to form a lattice shape. Also, in this embodiment, an angle θ1 formed by the inclined direction of the inclined portion 5 and the first direction and an angle θ2 formed by the inclined direction and the second direction are provided to be equal. The inclined direction is the direction in which the inclined portion 5 inclines. For the inclined portion 5 extending along the longitudinal direction of the bait agent housing recess 14, the short side direction is the inclined direction, and for the inclined portion 5 extending along the short side direction, the longitudinal direction is the inclined direction.

[0024] Next, the roof body 3 will be described. The roof body 3 that covers the upper part of the container body 2 is formed in a rectangular shape that is substantially the same size as the bottom plate portion 6. As shown in FIGS. 1 to 3, the upper surface of the roof body 3 is formed with an inclined gradient from the central portion toward each side portion. Thereby, rainwater and the like are drained well. Cylindrical support columns 15 are vertically provided at respective corner portions on the lower surface of the roof body 3. The tapered shaft 91 of the roof body support shaft 9 in the container body 2 is inserted into the lower surface opening hole 16 (FIG. 6) of the support column 15. The roof body 3 is integrated with the container body 2 to form a roof by fitting each support column 15 to the roof body support shaft 9.

[0025] When the roof body 3 is assembled integrally with the container body 2, as shown in FIG. 1, between the roof body 3 and the container body 2, there are formed on each side square intrusion openings 17 that are sandwiched vertically by the roof body 3 and the top flat surface 73 and are sandwiched horizontally by the roof body support shaft 9 and the support column 15.

[0026] In this embodiment, the container body 2 and the roof body 3 are each made of a synthetic resin (for example, polyethylene, polypropylene, polyester, polystyrene, polycarbonate, etc.) and may be transparent, semi-transparent, or opaque. Note that the materials of the container body 2 and the roof body 3 are not limited to synthetic resins, and any material that can form the rib 13 on the inclined portion 5 may be used, such as paper or metal. Also, the container body 2 and the roof body 3 may have different materials. Further, various additives such as an antistatic agent, an ultraviolet inhibitor, and a fungicide may be added to the synthetic resin. The shapes and sizes of the container body 2 and the roof body 3 are not particularly limited, and may be other than the rectangular shape in the illustrated example, such as a square, a circle, an ellipse, etc. The roof body 3 may be in a dome shape, an inverted bowl shape, etc. The joining of the container body 2 and the roof body 3 may be, in addition to the above-described fitting structure, ultrasonic welding, connection by a thin hinge, etc. Of course, the multi-legged pest bait agent container 1 according to this embodiment can also be used with the roof body 3 removed, such as when used indoors.

[0027] Next, with reference to FIG. 7, an effective way of accommodating the poisonous bait agent 100 in the multi-legged insect poisonous bait agent container 1 having the above-described configuration will be described. In FIG. 7, the container body 2 is provided with a poisonous bait agent accommodation recess 4 for accommodating the poisonous bait agent 100 at the center, and the inclined portion 5 surrounds the periphery of the poisonous bait agent accommodation recess 4 at a predetermined inclination angle. In the present embodiment, the inclination angle θ of the inclined portion 5 is formed at 60°. The amount of the poisonous bait agent 100 accommodated in the poisonous bait agent accommodation recess 4 is such that it does not exceed the virtual extension surface S (in this embodiment, a quadrangular pyramid-shaped surface) formed on the extension line of the inclination angle 60° formed by the inclined portion 5. By doing so, when a multi-legged insect such as a centipede starts climbing on the inclined portion 5 with an inclination angle of 60°, due to the inclination, even if the head of the multi-legged insect approaches the top of the inclined portion 5, the tip of the antenna will not touch the poisonous bait agent 100. And when the multi-legged insect reaches the top, the mouth of the multi-legged insect will approach the poisonous bait agent 100.

[0028] Further, in the multi-legged insect poisonous bait agent container 1 according to the present embodiment, a roof body 3 that covers the container body 2 is provided. Therefore, when the container body 2 is installed particularly outdoors, by attaching the roof body 3, it is possible to prevent foreign matters such as rain, dust, and fallen leaves from entering the poisonous bait agent accommodation recess 4. Thereby, the efficacy of the poisonous bait agent 100 can be maintained for a long period of time. Therefore, according to the multi-legged insect poisonous bait agent container 1 according to the present embodiment, the palatability to multi-legged insects can be remarkably improved.

[0029] Further, in the multi-legged insect poisonous bait agent container 1 according to the present embodiment, lattice-shaped ribs 13 are provided on the inclined portion 5. Thereby, at the intersection of the first convex portion 131 and the second convex portion 132, it is easy for the multi-legged insect to fix the tip of the leg (easy to catch the leg). Also, since the convex portions 131 and 132 are provided to be long in two directions, the first direction and the second direction, it is difficult for the multi-legged insect to slide the leg, and the multi-legged insect can easily enter up to the poisonous bait agent accommodation recess 4. In particular, when the inclination angle θ of the inclined portion 5 is as steep as 60° as in the present embodiment, the effect of the present embodiment is more easily obtained.

[0030] Also, as for the rib 13, it is preferable that the length of the first and second convex portions 131 and 132 in the longitudinal direction is 5 mm to 10 mm, the width in the short direction (width direction) is 0.5 mm to 1 mm, the height of the first and second convex portions 131 and 132 is 0.2 mm to 1 mm, the interval between the first convex portions 131 is 3 mm to 10 mm, and the interval between the second convex portions 132 is 3 mm to 10 mm. It is preferable that the shape of the intersection of the first and second convex portions 131 and 132 is bilaterally symmetric, and the interval between the intersections is 3 mm to 10 mm. Furthermore, it is preferable that θ1 formed by the inclination direction of the inclined portion 5 and the first direction = θ2 formed by the inclination direction of the inclined portion 5 and the second direction is 15 to 60°. By providing such a lattice-shaped rib 13, the myriapods can more easily enter up to the bait agent housing recess 4.

[0031] Furthermore, by providing a lattice-shaped rib 13 on the inclined portion 5, it becomes easier for the consumer to grip the inclined portion 5. Also, both the two first convex portions 131 and the second convex portions 132 that are long in the two directions of the first direction and the second direction can suppress the inflow of rainwater and the like, and can suppress the loss of the bait agent 100.

[0032] Also, in the myriapod bait agent container 1 according to the present embodiment, the angle θ1 formed by the inclination direction of the inclined portion 5 and the first direction and the angle θ2 formed by the inclination direction of the inclined portion 5 and the second direction are provided to be equal. Thereby, at the intersection of the first convex portion 131 and the second convex portion 132, it becomes easier for the myriapod to fix the tip of the leg, and the myriapod can easily enter up to the bait agent housing recess 4.

[0033] Also, in the myriapod bait agent container 1 according to the present embodiment, an inner peripheral wall portion 8 that surrounds the entire circumference of the housing range of the bait agent 100 is provided on the bottom surface of the bait agent housing recess 14. Thereby, a trench is formed between the outer peripheral wall portion 7 and the inner peripheral wall portion 8, and the loss of the bait agent 100 can be suppressed by this trench.

[0034] Note that the present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. In addition, the material, shape, dimensions, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

[0035] In the above-described embodiment, the angle θ1 formed by the inclination direction of the inclined portion 5 and the first direction, and the angle θ2 formed by the inclination direction of the inclined portion 5 and the second direction were provided to be equal, but it is not limited to this. The rib 13 may be provided in a lattice shape. For example, the first direction may be provided along the inclination direction, and the second direction may be provided along a direction orthogonal to the inclination direction.

[0036] According to the above-described embodiment, the inner peripheral wall portion 8 was provided on the bottom surface of the bait agent housing recess 14, but it is not limited to this. The inner peripheral wall portion 8 may not be provided.
