Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial bait used for fishing.

[0002]

2. Description of the Related Art Baits used for fishing include various artificial baits (lures, worms) in addition to natural baits that can be eaten by fish.
Is used. Simulated bait is required to have flexibility in order to attract fish by making it behave like a natural bait in water.
As a conventional artificial bait, for example, a bait using a polyvinyl chloride resin as a material is known.

[0003]

However, in order to obtain flexibility, the artificial bait made of a material mainly composed of a synthetic resin such as a polyvinyl chloride resin or a natural rubber is partially replaced with the artificial bait. When it is made thinner or thinner, the strength of the portion tends to be weaker and the portion tends to be easily torn.

When various additives are added to a polyvinyl chloride resin to give flexibility, the strength of the synthetic resin tends to decrease and the resin tends to be easily torn. In addition, some of these additives are considered harmful. For this reason, artificial bait using a polyvinyl chloride resin is not preferable from the viewpoint of environmental protection.

[0005] Further, polyvinyl chloride resin has a unique odor. For this reason, there is a tendency that even if a substance that induces fish is mixed with a pseudo bait made of a polyvinyl chloride resin, the inducement effect is not sufficiently exerted. In addition, the artificial bait not only has a smell, but also oil may seep out on the surface of the artificial bait particularly in summer, and the hands may become dirty when handling the artificial bait.

[0006] Therefore, an object of the present invention is to provide a more excellent artificial bait in view of the above tendency.

[0007]

The artificial bait of the present invention according to the present application comprises a synthetic resin (hereinafter also referred to as "SEBS resin") composed of a styrene-ethylene-butylene-styrene copolymer, and a plasticizer. Characterized by comprising a material mainly composed of a composition obtained by mixing

The composition containing the SEBS resin and the plasticizer contained in the artificial bait of the present invention has a specific gravity smaller than that of water, and is excellent in tensile elongation at break and tensile strength at break.
For this reason, the artificial bait of the present invention comprising a material containing this composition as a main component has the advantages of being buoyant, rich in flexibility, and resistant to tearing. For this reason, the artificial bait of the present invention is not only rich in flexibility but also excellent in so-called action appeal in combination with high buoyancy, and is closer to natural bait in water (including seawater; the same applies hereinafter). appear. For this reason, an improvement in the effect of inducing fish can be expected.

Further, since the artificial bait of the present invention is hard to be torn, it can be formed into a shape having a thin constricted portion or a thin portion which can be easily cut off during molding or use with a conventional polyvinyl chloride resin. it can. As a result, it is possible to obtain a simulated bait having a more flexible behavior.

Further, the artificial bait of the present invention is difficult to eat even when bitten by fish. Therefore, the artificial bait of the present invention can be used repeatedly.

As a plasticizer to be mixed with the composition, a paraffin-based or naphthene-based plasticizer is preferable.

The flexibility of the composition increases as the mixing ratio of the SEBS resin to the composition decreases, and the flexibility of the composition decreases as the mixing ratio increases. For this reason, the mixing ratio of the SEBS resin to the composition is preferably 2% to 30% by weight as the artificial bait. In order to give optimal flexibility to the artificial bait in consideration of the balance between softness and hardness, the mixing ratio is more preferably 5 to 20% by weight.

[0013] Further, the material of the artificial bait of the present invention, SE
The composition in which the BS resin and the plasticizer are mixed is substantially odorless. Therefore, by the smell of the composition of the artificial bait itself,
The fish are less likely to avoid the false bait. Also, when handling the artificial bait, the smell of the artificial bait does not stick to the hands. In addition, since the plasticizer of the present invention does not seep out of the plasticizer on its surface, hands are not stained by the plasticizer when handling the pseudo bait.

Further, if a substance that attracts fish is added to this composition, it can be expected that the odor-inducing effect is exhibited without being hindered by odor as in the case of polyvinyl chloride.

[0015] The composition used in the artificial bait of the present invention, which is a mixture of an SEBS resin and a plasticizer, is substantially harmless as will be described later in the description of the embodiments. Therefore, the dummy bait of the present invention is preferable from the viewpoint of reducing environmental pollution as compared with a conventional bait using a polyvinyl chloride resin.

Further, when the artificial bait is used in water at a certain depth, the above-mentioned artificial bait is too light and does not sink to the required depth or bottom in the water, but floats on the surface or in a shallow place. There is a fear. In this case, it is preferable that the weight of the artificial bait is mixed with a weight adjusting material in the above-described material. In a preferred embodiment of the present invention, calcium carbonate or calcium carbonate and glass fiber may be added as the conditioning material.

As described above, the artificial bait prepared by adding the weight adjusting material to the material of the artificial bait in an appropriate amount corresponding to the depth in the water sinks in the water by its own weight, and the required artificial bait according to the design is required. It is possible to float at a depth.

In practicing the present invention, preferably, the weight adjusting material is included in the entire dummy bait, and the amount added to the lower part in the vertical direction of the dummy bait is larger than the amount added to the upper part. It is better to keep a lot.

As described above, when the weight of the pseudo bait is weighted, when the pseudo bait is formed into, for example, a fish shape, the pseudo bait resembles the natural shape of a fish in which the abdomen is lower and the back is upper. Simulated bait can be suspended in water. Such an underwater floating posture of the artificial bait is a posture in which fish prefers to eat.

This composition does not contain any glitter or pigment other than the SEBS resin and the plasticizer.

[0034]

[Table 1]

As shown in Table 1, the tensile yield strength of a composition in which the SEBS resin and the liquid paraffin were mixed at a weight ratio of 13 to 100 was tested according to the test method of JIS-K7113. It was 2.0 kgf / cm ² .

The tensile breaking strength of this composition was measured according to JIS.
The composition did not break when tested according to the test method -K7113. Therefore, it was found that this composition had a very excellent tensile strength at break and was hard to cut.

The tensile elongation at break of this composition was determined by JI
When tested according to the test method of S-K7113, 1
000%. This value of 1000% is about 10 times the tensile elongation at break of natural rubber rubber. Therefore, it was found that this composition had a very excellent tensile elastic elongation and was rich in flexibility.

The specific gravity of this composition is JIS-K7
When the test was conducted in accordance with the test method of No. 112, about 0.85
Met. Therefore, this composition was found to have high buoyancy.

Next, referring to Table 2, the weight ratio of the SEBS resin and the plasticizer used in the artificial bait of the present invention was 13: 1.
The test results of the dissolution test of the composition mixed at a ratio of 00 will be described. Table 2 shows the test results of the physical properties of the composition used for the artificial bait according to the embodiment. This test is based on the Food Sanitation Law, Food and Additives Standards (Notification No. 370 of the Ministry of Health and Welfare, No. 370 of 1959), the standards for toys or their raw materials and the manufacturing standards for toys, vinyl chloride resin paints used in the manufacture of toys, and chlorides. The test was carried out in accordance with a material mainly composed of a vinyl polymer (Notification No. 257 of the Ministry of Health and Welfare in 1972).

[0040]

[Table 2]

As shown in Table 2, the dissolution test result of this composition for heavy metals was 1 ppm or less (as Pb). Also, the cadmium dissolution test results of this composition,
It was 0.5 ppm or less. The arsenic elution test result of this composition was 0.1 ppm or less (as As ₂ O ₃ ). Further, the potassium permanganate consumption of this composition was 2.8 ppm. The evaporation residue of this composition was 1.5 ppm. In addition, no elution of the coloring agent of this composition was detected (no elution).

From the results of the dissolution test, it can be seen that this composition has no toxicity for the test items and is preferable from the viewpoint of environmental protection. Therefore, it can be expected that the artificial bait of the present invention composed of a material containing this composition as a main component is also preferable from the viewpoint of environmental protection.

When a pseudo bait is made of a material containing such a composition as a main component, the pseudo bait may be too light in its own weight and may not sink to a required depth in water by its own weight. There is a way to increase the weight of such artificial bait. What is necessary is just to add a weight adjusting material to the material of this pseudo bait, and to produce a pseudo bait.

A material suitable as such a weight adjusting (or adjusting) material is calcium carbonate. When this calcium carbonate is added in an amount of 22 to 24% by weight to the above-mentioned composition (composition) of SEBS resin and liquid paraffin, the specific gravity of the composition becomes 1.0 which is substantially equal to water. Therefore, the artificial bait made of the composition to which calcium carbonate is added does not float or sink in water. Therefore, if the weight is increased by adjusting the amount of calcium carbonate added (filled) corresponding to the depth at which the artificial bait is desired to float, the artificial bait can be floated at that depth in the water. The amount of addition may be determined as an approximate amount with respect to the planned water depth.

In addition to such inorganic calcium carbonate, if necessary, inorganic glass fibers may be added to adjust the weight. Glass fibers include powdery and granular ones, but either may be used. The powdery glass fiber provides an opaque pseudo bait, and the granular glass fiber provides a transparent pseudo bait. The amount of the glass fiber added may be an appropriate amount according to the design.

Other materials that can be added (filled) for weight adjustment include the following inorganic fillers such as carbon black, powdered silicon (white carbon), hydrochloric magnesium carbonate, alumina, and barium sulfate. , Mica powder, zinc white, silicon earth, talc, graphite powder, asbestos powder and the like, and any filler may be used depending on the design.

By the way, this weight adjusting material is made of the above-mentioned S.
In the composition (composition) of EBS resin and liquid paraffin,
Preferably, if it is uniformly filled, it will be uniformly contained in the prepared pseudo bait. However, the biting rate of the fish on the artificial bait changes depending on whether the floating posture of the artificial bait in the water (floating state) is a soil-like state. In order to improve the biting rate, for example, in the case of a fish-type artificial bait, it is preferable to make the artificial bait appear as if the fish are swimming naturally. Therefore, in the vertical direction of the pseudo bait,
It is good to make a difference in the weight of the artificial bait. In the case of the fish-type artificial bait, it is preferable that the above-mentioned weight adjusting material is unevenly distributed so that the stomach side of the fish is heavier than the back side.

Thus, in the vertical portion of the artificial bait,
By including the adjusting material so that a difference in weight occurs between the upper part and the lower part, the pseudo bait floats in water in a posture determined by the difference in weight. The fish-shaped artificial bait floats with the abdomen down and the back side up, as if the fish were swimming with the whole body facing sideways.

A method of preparing a pseudo bait having such a weight difference will be briefly described by taking a fish-type pseudo bait as an example.

The upper half and the lower half of the body of the fish-like artificial bait are separately formed in the vertical direction. The above composition for the upper half is mixed with, for example, an A amount of a weight adjusting material, and only the half is molded. On the other hand, a weight adjusting material is mixed into the above-described composition for the lower half, for example, in an amount of B, and only the half is molded. At this time, when using the same weight adjusting material, the B amount is set to be larger than the A amount. When different weight adjusting materials are used in the lower half and the upper half, the amounts of A and B are determined and mixed so that the lower half of the dummy bait is heavier than the upper half. Just do it.

After the upper half and the lower half are molded, the two parts are joined together and, if necessary, heated and pressed so that the two parts are not easily separated during use. In the state, join. If necessary, the bonding portion may be joined using a suitable adhesive. Alternatively, the two halves may be joined together so that the two halves do not peel off from each other using other suitable means.

Alternatively, one of the halves is first molded,
By inserting the molded half into the corresponding part of the mold of the other half and molding the remaining half with the same molding material, an integrated pseudo bait can be formed.

In each of the embodiments described above, only examples in which these inventions are configured using specific materials and under specific conditions have been described. However, these inventions can be subjected to many changes and modifications. For example, in the above-described embodiment, an example of a so-called worm has been described, but the shape of the artificial bait of the present invention is not limited to this, and for example, a shape resembling an arthropod such as an insect or a small fish. May be formed.

[0054]

The composition in which the SEBS resin and the plasticizer are mixed has a specific gravity smaller than that of water, and is excellent in tensile elongation at break and tensile strength at break. Therefore, the artificial bait of the present invention, which is made of a material containing this composition as a main component, has the advantages of being buoyant, rich in flexibility, and resistant to tearing. For this reason, the artificial bait of the present invention is not only rich in flexibility but also excellent in so-called action appeal in combination with high buoyancy, and looks closer to natural bait in water. For this reason, an improvement in the effect of inducing fish can be expected.

Further, since the artificial bait of the present invention is hard to be torn, it can be formed into a shape having a thin constricted portion or a thin portion which is easily cut off during molding or use with a conventional polyvinyl chloride resin. it can. As a result, it is possible to obtain a simulated bait having a more flexible behavior.

Further, the artificial bait of the present invention is difficult to eat even if bitten by fish. Therefore, the artificial bait of the present invention can be used repeatedly.

Further, SE, which is a material of the artificial bait of the present invention,
The composition in which the BS resin and the plasticizer are mixed is substantially odorless. Therefore, by the smell of the composition of the artificial bait itself,
The fish are less likely to avoid the false bait. Also, when handling the artificial bait, the smell of the artificial bait does not stick to the hands. In addition, since the plasticizer of the present invention does not seep out of the plasticizer on its surface, hands are not stained by the plasticizer when handling the pseudo bait.

Furthermore, if a substance that attracts fish is added to this composition, it can be expected that the odor-inducing effect is exhibited without being inhibited by the odor as in the case of polyvinyl chloride.

The composition used in the artificial bait of the present invention, which is a mixture of SEBS resin and plasticizer, is substantially harmless. Therefore, the dummy bait of the present invention is preferable from the viewpoint of reducing environmental pollution as compared with a conventional bait using a polyvinyl chloride resin.

According to the artificial bait of the present invention, calcium carbonate, glass fiber or the like is added (mixed or filled) in an appropriate amount as a weight adjusting material.
In the depth of the water according to the type of this adjusting material and its addition amount,
Simulated bait can be suspended.

Also, in some cases, if the above-mentioned adjusting material is added so that the lower part of the artificial bait in the vertical direction is heavier than the upper part, the artificial bait is adjusted in the vertical direction and floated. Can be done.
