Abstract

PROBLEM TO BE SOLVED: To provide a fishing lure having high flexibility as well as strength, excellent luring action and good handleability. SOLUTION: A highly transparent composition to form an outer layer 3 is poured into a cavity 22 in an amount corresponding to the volume of the transparent part, i.e., the outer layer 3. A composition having high hardness and corresponding to the inner layer 2 compounded with a colorant is immediately poured into the center part of the cavity 22 before the cooling of the transparent composition to lose its fluidity. The amount of the material for the inner layer 2 to be poured into the cavity is set to sufficiently fill the cavity 22 together with the material for the outer layer 3. The former composition for the outer layer 3 is pressed against the mold surface by the filling of the latter composition for inner layer into the center part to form a transparent lure 1 composed of the colored inner layer 2 and the transparent outer layer 3 and similar to a small fish.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fake bait for fishing,
More specifically, the present invention relates to a pseudo bait having the appearance, feel, elasticity, and movement in water like a live bait, and further having excellent fishhook retention and fish attracting effects, and a method for producing the same.

[0002]

2. Description of the Related Art Fishing baits include live foods such as earthworms, gokai, shrimp, and krill, natural baits that can be eaten by fish kneaded with fish meal, udon, and other real foods. There are fake baits such as lures, worms, and the like made like. The shape, fragrance,
There are many types of colors that are suitable for the target fish and the environment in which they are caught, and are commercially available.
In addition to metals and hard plastics, hydrophilic plastics such as polyvinyl alcohol and rubbery soft plastics such as polyvinyl chloride are used.

The conditions required for a pseudo bait include, first, appearance, feel, and behavior similar to raw bait, ie, flexibility, elasticity, or color, shape, and odor that are easy to attract the attention of fish in order to enhance fishing results. Second, it is required to be easy to use with sufficient mechanical strength under actual use conditions.

[0004] In order to obtain such artificial bait, Japanese Patent Laid-Open No.
As can be seen in JP-A-103565 and JP-A-4-40845, artificial baits made of various materials and configurations have been developed.

[0005]

However, these pseudo baits disclosed so far have been used under various conditions originally required as described above, that is, appearance, feel, behavior and sufficient mechanical strength similar to raw baits. Conditions cannot be satisfied at the same time. For example, JP-A-5-103565 discloses that
A pseudo bait in which a salt is contained in the main body of the pseudo bait of vinyl chloride sol is disclosed, but the pseudo bait is composed of the same color, the same hardness and the same mechanical strength as a whole, and is a real living small scale. Since the form and behavior do not resemble that of a raw bait such as a fish at all, it cannot be expected to have a sufficient attraction effect, and it is insufficient as a simulated bait especially for sea fishing.

Further, in the artificial bait disclosed in JP-A-4-40845, the outer layer is composed of a high-strength water-containing polymer gel, and the core layer is composed of a low-strength gel or sol. It is a stick-shaped artificial bait extruded. This simulated bait can feel similar to raw bait, but its actual shape will not resemble what sea fish like small fish prefer to eat. In particular, the behavior in water will be different from raw bait,
I can't expect enough fishing results.

SUMMARY OF THE INVENTION The present invention provides a pseudo bait which satisfies the conditions required for a pseudo bait in the above-mentioned situations, that is, it can satisfy fishing conditions and have sufficient strength which is excellent in usability. The purpose is to provide.

More specifically, the flexibility and elasticity of the simulated bait closely resembles that of a live bait, is excellent in attracting fish, and its physical properties can be adjusted depending on the type of live bait. The purpose is to provide a dummy bait having durability.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a dummy bait 1 according to the present invention.
In the state of use. The artificial bait 1 has a substantially spindle-shaped main body 11, a thin tail 12 connected to a rear end of the main body 11, a head 13 protruding from the front end of the main body 11, And a dorsal fin portion 14 formed on the side surface of the portion 11, and as a whole,
It is similar to the shape of small fish that fishes prefer to eat. A wire 15 is disposed so as to extend obliquely through the main body 11, and a yarn 15 is connected to one end of the wire 15 at the distal end of the main body 11, and a main body opposite to the dorsal fin 14. Wire 1 exposed on 11 side
At the other end 5, a hook 17 is provided.

The artificial bait 1 of the present invention has an internal structure by continuously injecting two types of materials into a mold.
It has a two-layer structure including an inner layer 2 and an outer layer 3.

That is, the artificial bait 1 is based on a composition in which 100 parts or more of a lipophilic polymer substance is blended with 100 parts or more of a lipophilic mineral oil-based softening agent as a lipophilic polymer substance, and By changing the compounding amount, two types of compositions having different elastic moduli are prepared. Further, a coloring agent is blended if necessary, and compositions of different colors are used.

More specifically, in the present embodiment, in order to produce the artificial bait 1 having a transparent feeling similar to a small fish in the sea, a rear end side of the artificial bait 1 including the tail part 12 and the dorsal fin part 14 is provided. Part and the outer layer part 3 constituting the surface part of the main body part 11,
The inner layer 2, which is formed of a colorless and transparent composition and is disposed at the center of the tip side portion of the main body 11, at least in the center of the portion through which the wire 15 penetrates, is provided with a coloring agent ( For example, a composition containing blue or red) is used.
Also, in order to realize subtle behavior in water, the tail 12
The outer layer portion 3 constituting the dorsal fin portion 14 is a soft and soft compound having a relatively low hardness. On the other hand, the inner layer 2 receiving the hook 17 and the line 16 has a higher hardness than the outer layer 3.

FIG. 2 is a process explanatory view showing a method of manufacturing the artificial bait 1. The mold 21 has a cavity 22 corresponding to a desired shape of the artificial bait 1. In the cavity 22, the front end side of the main body 11 serves as a material injection port, and the tail 12 side is sealed. This type 2
First, a composition having high transparency corresponding to the outer layer portion 3 is injected from the outer layer nozzle 23 into the cavity 22 by a volume corresponding to the volume desired to be the outer layer portion 3 (step). (A)). The material for the outer layer portion 3 injected as described above is supplied to the cavity 2 as shown in step (b).
2 near the material injection port. Then, immediately before the composition is cooled and loses fluidity, a composition corresponding to the inner layer portion 2 containing the colorant is injected from the inner layer nozzle 24 toward the center of the cavity 22 (step). (C)). At this time, the amount of the material for the inner layer portion 2 to be injected is:
The amount is set such that the inside of the cavity 22 can be sufficiently filled together with the material for the outer layer portion 3. In addition, the pressure at the time of subsequent injection is such that the composition for the outer layer portion 3 initially filled is injected at a pressure as high as possible. As a result, the composition for the inner layer portion 2 that has entered later is filled in the center portion by pressing the first composition for the outer layer portion 3 against the mold surface, and the colored inner layer portion 2 is transparent. A transparent fish-like artificial bait 1 composed of the outer layer 3 and the transparent feeling is formed.

The simulated bait 1 configured as described above has a thin tail portion 12 that is soft, so that it can realize subtle behavior and vibration in water, and has a hardness at a portion where the fishing hook 17 is hooked. Since the height is high, the holding power of the fishing hook 17 can be increased, and a movement similar to a living small fish as a whole can be given. That is, the minimum mechanical strength can be secured without sacrificing the required flexibility in the attraction action, and an ideal dummy bait can be obtained.

As an example of the hardness of the inner layer portion 2 and the outer layer portion 3, Asker C specified in JIS K6301 is used.
As the hardness, the inner layer 2 has a hardness of 10 to 75, and the outer layer 3 has a hardness of 0 to 1.
Desirably, it is 0.

Further, by the same manufacturing method as described above, it is possible to make the outer layer 3 a composition containing a high-concentration fish-collecting agent, or to mix the outer layer 3 with a high-concentration fluorescent paint or luminous paint. It is possible to obtain the artificial bait 1 having a higher incentive action by efficiently using expensive compounding materials such as a fish collecting agent and a fluorescent paint.
