DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing tackle such as a lure and a method of manufacturing the same.

[0002]

2. Description of the Related Art In-progress fishing gear such as lures must be designed to appeal to fish and the like. for that reason,
For example, a means of distinguishing the color of a body such as a lure is employed, but the coloring is troublesome. In addition, since lures and the like often invite fish and the like by their movement, it is necessary to provide some buoyancy to make it easy to move in water, but it has been difficult to provide appropriate buoyancy.

[0003]

SUMMARY OF THE INVENTION The present invention makes it easy to color-code the body in order to give an appearance appealing to fish and the like, and to provide buoyancy as appropriate so as to make the movement easy to invite fish and the like. It is an object to provide a fishing tackle for a lure or the like and to provide a manufacturing method capable of easily and efficiently manufacturing the fishing tackle for a lure or the like.

[0004]

In order to solve the above-mentioned problems, a fishing tackle such as a lure according to the present invention comprises an outer surface layer 3 and an inner core 4 covered by the surface layer 3. The surface layer portion 3 and the core portion 4 are provided with a body 1 formed of a different kind of plastic material.

In order to solve the above-mentioned problems, a method of manufacturing a fishing tackle such as a lure according to the present invention is described. 10 is injected in a short shot state, and then the other injection cylinder is used to dissimilar plastic material 1
1 is injected into the same cavity 8, and the plastic material 10 injected earlier is pushed outward by the plastic material 11 injected later and adhered to the mold wall. Part 3
The core 4 inside the body 1 covered with the surface layer 3 by the plastic material 11 is formed.

[0006]

1 and 2 show a lure as an embodiment of a fishing tackle such as a lure according to the present invention. More specifically, it shows a lure called a squid angle for squid fishing. In the figure, reference numeral 1 denotes a plastic body, and reference numeral 2 denotes a hook-shaped needle attached to one end of the body 1. The body 1 has an outer surface layer 3 and an inner core 4 covered with the surface layer 3, and has a sandwich structure as a whole. The outer surface portion 3 of the body 1 is colorless and transparent, and the inner core portion 4 is colored red. The inner core 4 is foamed.

Next, FIG. 3 shows a manufacturing process of the squid angle body 1 described above. The body 1 is molded by an injection molding machine having two injection cylinders 5 and 6 and one mold 7. The two injection cylinders 5 and 6 can be injected into the cavity 8 of the same mold 7. First, a transparent plastic material 10 is injected from one injection cylinder 5 into the cavity 8 of the mold 7. The injection of the plastic material 10 is in a short shot state. Next, another plastic material 11 is injected into the same cavity 8 from the other injection cylinder 6 by switching the injection valve 9. This plastic material 11
Is colored red and contains a foaming agent. The plastic material 11 injected afterwards pushes the plastic material 10 injected earlier outward and spreads to make close contact with the mold wall. Finally, the plastic material 10 is again injected to perform gate sealing, and then the mold 7 is slightly opened to completely foam the plastic material 11. Then, after cooling, the mold 7 is opened to obtain the lure body 1 having the transparent plastic surface layer 3 on the outside and the foamed and colored plastic core 4 on the inside. Can be.

In the present invention, two kinds of different plastic materials are used. The different kinds include those having different colors, different materials, different additives, and the like. Further, when different colors are used, the colors are not limited to colorless and red as in the above embodiment, but various color combinations are possible. Further, the present invention is not limited to the lure as in the above embodiment, but also covers other fishing gear used for fishing.

[0009]

As described above, the fishing tackle for a work such as a lure according to the present invention has the body 1 composed of the surface layer 3 and the core 4 as described above, so that the surface layer 3 is made transparent as in the above embodiment. In addition, it is possible to easily color the core part 4 and color-code it into two colors, so that the appearance that appeals to fish or the like can be obtained. Further, as in the above-described embodiment, the core part 4 is foamed. It is also possible to make the body 1 easily movable in water by giving it buoyancy. The foaming of the core 4 also has the advantage of preventing the occurrence of sink marks and improving the appearance quality. In addition, there is an advantage that recycled plastic can be recycled as a material of the core portion 4 by adopting a sandwich structure of the surface layer portion 3 and the core portion 4. In addition, the method for manufacturing a fishing tackle such as a lure according to the present invention has an advantage that the body 1 having the sandwich structure of the surface layer portion 3 and the core portion 4 can be manufactured very easily and efficiently with only one mold 7. There is.
