DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The top cover of the ant poison bait storage container of the present invention contains 0.005 to 0.05% by weight of carbon black. If the carbon black content is less than 0.005% by weight, the ability to attract the ants stored therein decreases. If the carbon black content exceeds 0.05% by weight, the visibility of the inside of the storage container decreases.

[0010] The components in the top cover other than the carbon black are usually resin components. As the resin component, it is preferable to use a styrene-based resin, and examples of the styrene-based resin that can be used include general-purpose polystyrene (GPPS), high impact polystyrene (HIPS), styrene-acrylonitrile copolymer (SAN), and acrylonitrile-butadiene-styrene copolymer (ABS). In addition to the resin component, an antistatic agent, an antioxidant, an ultraviolet absorber, and the like may be further added.

[0011] The top cover can be produced by melt-kneading raw materials such as carbon black and resin components in a known kneading machine such as a pressure kneader to obtain resin pellets, and then feeding the resin pellets into an injection molding machine.

[0012] The lower cover is usually manufactured using the same material as the upper cover for ease of manufacture and cost reasons, but may be modified as appropriate without impairing the effects of the present invention.

[0013] The shape of the ant poison bait storage container of the present invention is not particularly limited as long as it has a lower lid provided with an ant poison bait storage section and an upper lid arranged so as to face the lower lid, and examples include a cube, rectangular parallelepiped, polygonal prism, cylinder, polygonal pyramid, cone, etc. Of these, a preferred shape for the ant poison bait storage container is the ant poison bait storage container shown in Figure 1 (hereinafter sometimes referred to as container 1).

[0014] Examples of the internal configuration of the ant poison bait storage container include containers having the configurations shown in Figures 1 to 6. The details will be described below.

[0015] The container 1 is provided with a bottom lid 10 provided with an ant poison bait storage surface 12, an top lid 20 arranged opposite the bottom lid, first to fourth connecting parts 31 to 34 connecting the bottom lid and the top lid with a gap between them, and first to fourth protruding parts 41 to 44 for fixing the poison bait inside the container.

[0016] The bottom cover 10 is made of a resin material and has a generally flat plate shape, and has an octagonal shape when viewed from the bottom of the container 1 as shown in FIG.

[0017] An inner surface 10a of the bottom cover 10 located on the inside of the container 1 may be textured over the entire surface.

[0018] A protrusion 11 is formed on the inner surface 10a of the bottom cover 10, extending in the circumferential direction and protruding toward the top cover 20. As shown in FIG. 6, the protrusion 11 is continuous to form a ring, and the center of the ring substantially coincides with the center of the bottom cover 10.

[0019] The inner portion of the protrusion 11 serves as a poison bait storage surface 12 for storing poison bait.

[0020] The thickness of the lower cover 10 is preferably 0.5 mm to 3 mm.

[0021] 5, the inner surface 10a of the bottom cover 10 is provided with first to fourth connection receiving portions 31a to 34a which are integrally formed with the bottom cover 10 to constitute the first to fourth connection portions. The connection receiving portions 31a to 34a have recesses into which the connection insertion portions 31b to 34b can be inserted, respectively.

[0022] The top cover 20 is made of a resin material and has an octagonal shape when viewed from the top surface of the container 1 as shown in FIG.

[0023] The inner surface 20a of the top cover 20 located inside the container 1 is provided with first to fourth protrusions 41 to 44 for fixing the poison bait stored in the container 1 to the poison bait storage surface 12. The tips of these protrusions are steeply shaped.

[0024] 5, there are provided first to fourth connecting insert portions 31b to 34b which are integrally formed with the upper cover 20. The connecting insert portions 31b to 34b are inserted into the connecting receiving portions 31a to 34a to form the connecting portions 31 to 34.

[0025] The top lid 20 is provided with a flat surface 20b and an inclined surface 20c on its outer periphery that approaches the bottom lid 10 the closer it is to the outer periphery, and the center of the flat surface 20b approximately coincides with the center of the top lid 20. In addition, by providing an end surface 20d on the outer periphery of the inclined surface 20c so as to be perpendicular to the bottom lid, it is possible to prevent rainwater and dust from entering the container 1.

[0026] The outer dimension W1 of the lower cover 10 and the upper cover 20 is preferably 30 mm to 50 mm, and the outer dimension W2 of the flat surface 20b is preferably 10 to 20 mm. The inclination angle θ of the inclined surface 20c shown in Fig. 4 is preferably 3 to 7°. The outer dimension W3 of the end surface 20d is preferably 1 to 3 mm.

[0027] The dimension h in the direction in which the bottom cover 10 and the top cover 20 are spaced apart is designed so that poison bait can be stored therein.

[0028] As shown in Fig. 7, before use, the containers 1 may be integrated in a connected state, for example, into six pieces. A connecting piece 60 is formed on the outer periphery of the bottom cover 10 of the container 1, which connects to the outer periphery of the bottom cover 10 of an adjacent container 1, and a connecting piece 61 is similarly formed on the outer periphery of the inclined surface 20c of the top cover 20. The connecting pieces 60 and 61 can be broken by applying a force in the bending direction, so that the containers can be separated.

[0029] To connect six containers 1, first, six bottom lids 10 are integrally molded so that they are lined up two vertically and three horizontally and connected by connecting pieces 60. Similarly, six top lids 20 are integrally molded so that they are connected by connecting pieces 61.

[0030] Then, the upper lid 20 is placed over the lower lid 10, and the lower lid 10 and the upper lid 20 are fitted together as shown in FIG. 5, resulting in six containers 1 being connected together as shown in FIG. 7.

[0031] Poison bait is produced by mixing an insecticide such as fipronil, attractants such as animal protein powder, grain flour, starch, sugar, and vegetable oil, thickeners such as carboxymethylcellulose, viscosity regulators such as glycerin, preservatives, water, etc.

[0032] The ant poison bait storage container of the present invention stores poison bait and is installed in a location where it is desired to control ants such as Argentine ants, brown ants, yellow ants, and house ants.
