EMBODIMENT OF THE INVENTION Below, this invention is demonstrated by embodiment to show in drawing.

1 and 2 show an embodiment of the artificial fishing bait according to the present invention, Figure 1 is an exploded perspective view, Figure 2 is a partially cut perspective view.

As shown in FIG. 1 and FIG. 2, the artificial bait 1 for fishing of this embodiment has the case 2, the bait main body 3, the weight member 4, and the stopper member 5. As shown in FIG. The artificial bait 1 for fishing of this embodiment is formed in the substantially columnar shape about 10 mm in diameter and about 250 mm in total length.

The case 2 accommodates the bait body 3 therein, and is formed in a straw shape that forms a substantially cylindrical shape having a diameter of about 10 mm, a thickness of about 0.5 mm, and a length of about 200 mm, for example. One end of the inner hole of the case 2, shown in the lower left of FIG. 1, is a mounting portion 2a for mounting the weight member 4, and is shown in the upper right of FIG. 1 of the inner hole of the case 2. The other end side is a stopper attachment part 2b for mounting the stopper member 5.

In addition, the size and shape of the case 2 can be variously changed depending on the depth of the fishing ground, the type of food of the fish to be caught in the fishing ground, the operation method and the purpose of using the artificial bait.

That is, the size or shape of the case 2 may be a real size and shape such as horse mackerel, sardines, mackerel, squid, etc. according to the prey of the fish to be caught, or may be an irregular hollow shape having at least two openings. In view of the fish, and in view of handling, storage properties and productivity, it is preferable to form the cylinder or the like in a cylindrical shape having a polygonal cross section.

As the material of the case 2, a natural material which can be decomposed or dissolved by water-soluble synthetic resin, seawater or fresh water of a fishery, or the like can be used. In this embodiment, polyvinyl alcohol (PVA) is used.

As said PVA, the thing which reduced 70-90% partially is preferable, for example.

In particular, the material of the case 2 is not limited to the PVA of the present embodiment, and may be decomposed or dissolved by seawater or fresh water of fishery, for example, from paper, mantrios, etc. Therefore, it can be used selectively.

The bait main body 3 exhibits a picking function. The bait main body 3 of this embodiment is plural, ie, two pairs, for example, one end of the rod-shaped body which each forms substantially cylindrical shape of about 8 mm in diameter and about 100 mm in length. It is a shape provided with the inclined surface 3a which cut | disconnected obliquely over about half of the total length. In addition, the two bait bodies 3 are arranged in the case 2 so as to form a substantially cylindrical shape having a diameter of about 8 mm and a length of about 100 mm so that the respective inclined surfaces 3a face each other. It is formed so that the movement is free.

In addition, the number, size and shape of the bait main body 3 can be variously changed depending on the depth of the fishing ground, the kind of food to be caught in the fishing ground, the fishing method and the purpose of using the artificial bait.

That is, the size of the bait main body 3 may be a size that can be accommodated inside the case 2 in an unused state, and the shape of the bait main body 3 is close to the fish and the operation when floating is floated. It is preferable to form a rod shape with one end having a buoyancy larger than the other end in view of the floating operation and considering the handling, storage and productivity. Such a shape is not particularly limited to the shape of the present embodiment, but in various shapes such as a multistage rod shape having a diameter larger than the other end, a tapered shape, and one end of a cylindrical shape fixed to one end. It can be used depending on the needs of the design concept.

In this embodiment, two colors of white and blue are used as the colors of the two bait bodies 3. In this way, it is possible to express the stomach and the like of the small fish, that is, by the small fish group such as horse mackerel, sardine, mackerel and the like.

As a raw material of the bait main body 3, in the present embodiment, a foam having a specific gravity smaller than that of seawater or fresh water consisting of starch, PVA, and water is used.

As the starch-based composition, a water-containing composition having a weight ratio of starch / PVA of 10/1 to 10/4 on a dry basis is preferable. Although the foam obtained by starch only becomes a hard and brittle foam, the composition which mix | blended PVA with starch shows the improvement of moldability and the curvature degree. As PVA, the degree of polymerization is preferably 1000 or more, preferably 2000 or more. PVA has a desirable degree of 70% or more and 90% or less in terms of compatibility and processability. If the weight ratio of starch / PVA exceeds 10/1, there is almost no physical property improvement, and below 10/4, the foamability deteriorates. The water content of the composition is preferably adjusted so that the water content of the hydrous composition immediately before the extruder exit is in the range of 8% or more and 20% or less. Too little moisture causes too much extruder back pressure, resulting in poor molding precision, and too much moisture tends to cause cell shrinkage due to moisture condensation. In addition, the moisture in the composition to be supplied to the extruder is better to be mixed than the moisture in the composition immediately before the extruder exit, and in this case, it may be adjusted to be discharged in the above range by releasing excess moisture from the outlet of the extruder.

Depending on the conditions when the artificial bait 1 for fishing of this embodiment is actually used by a fishing ground, water resistance may be required more. For example, when set at a deep position on the surface of the sea, it is necessary to make the underwater residence time longer, so that it melts on the way or that the artificial baits for fishing 1 do not fuse together. In addition, the operation speed in a fishery with a high water temperature also increases the speed of dissolution, the same can be said. In such a case, the water solubility of the composition can be controlled by adding a small amount of ethylene-vinyl alcohol copolymer and / or aliphatic polyester to the composition. As for the ethylene-vinyl alcohol copolymer, those having an ethylene content of 20 to 50 mol% and a degree of reduction of 90% or more are suitably used. If the ethylene content is too small, the water solubility is remarkable, and if it is too large, the compatibility with the starch composition becomes weak and it is difficult to biodegrade. Aliphatic polyesters are selected from condensation polymers of aliphatic diols and aliphatic dicarboxylic acids, condensation polymers of hydroxycarboxylic acids, ring-opening polymers of aliphatic lactones, ring-opening polymers of aliphatic lactide, and copolymers thereof. For example, polybutylene succinate, polyperacid, polycaprolactone, polylactic acid and the like are suitably used. The ethylene-vinyl alcohol copolymer and the aliphatic polyester may be used alone or in combination. As for the usage-amount, 10 weight% or less is preferable in total of these. The amount of use exceeding 10% by weight is insufficient in the foaming power of the contained moisture, and the cost is high.

Nucleating agent, bone agent, plasticizer, etc. can be added to this starch type composition suitably besides the above. Nucleating agents are effective for generating foaming at uniform and fine cell sizes, and several microns of tar may be suitably used. The addition amount may be about 0.05 to 2% by weight. The lubricant is effective for preventing seizure of the screw and suppressing internal heat generation by shearing, and stearic acid or the like is suitably used. The addition amount may be about 0.5 to 2% by weight. The plasticizer is effective for improving the formability of starch and PVA, and glycerin, urine, polyethylene glycol and the like are preferably used. The addition amount can be used in 10% or less of range.

In addition, in the molding process of the starch-based composition, when foaming power is insufficient only by water, a chemical foaming agent such as azodicarbonamide or sodium bicarbonate may be used auxiliary. It is also possible to carry out processing such as coloring, flavoring, flavoring or glossing on the composition in order to give the texture a similar feel and appearance. Coloring can give a feeling of a living fish by coloring the color which looks blackish in water like red, for example in a stem form. Although coloring to a rod-shaped foam may be performed by printing or spraying after shaping | molding, a coloring master medium may be introduce | transduced in various circumference immediately before a mold during extrusion, and a stripe shape may be formed in a rod-shaped foam. In addition, an odor or taste can be imparted to the rod-shaped foam by adding attractants such as amino acids, nucleic acids, sardine oil, and krill shrimp extract to the composition. Small pieces of aluminum foil may also be added to the composition or adhered to the rod-shaped foam surface to give a light reflecting effect.

Extrusion of the starch-based composition can be carried out by a conventional twin screw or single screw extruder. The twin screw extruder is well mixed and foams can be made directly from the powder stock, but a single screw extruder is sufficient if the composition is pre-granulated. The extrusion temperature is preferably in the range of 150 ° C to 180 ° C as the resin temperature. Too low a temperature results in insufficient mixing, and too high a temperature may cause some pyrolysis. In addition, the extrusion conditions may be appropriately determined in consideration of the exothermic properties according to the extruder characteristics (barrel cooling, screw groove depth, mold diameter and land length). The diameter of the rod-shaped body is determined by the mold diameter, the drawing speed and the expansion ratio. If extruded slightly after extrusion, linearity and surface smoothness are improved. The diameter of the foam rod-shaped body is preferably about 6 to 10 mm based on the small sardines. In order to increase the visibility of bonito, it is important to have a linear horizontal movement in addition to the size that is easy to feed, in order to do so, the length of the rod-shaped body is preferably about 6 to 20 times the diameter. If the length is too short, the swimming movement is insufficient, it becomes a simple injury, and if it is too long, the swimming direction is easily curved, and the rotational movement becomes unnatural.

In addition, the material of the bait main body 3 is not particularly limited to the starch-based composition of the present embodiment, and has a buoyant force that can float toward the sea surface or the surface of the fishery, and is capable of being decomposed or dissolved at least by the seawater or fresh water of the fishery. It is preferable to form by.

As the constitution related to buoyancy, the constitutions formed by combining foams and solids alone or in combination, for example, those having a small specific gravity of the material itself or a structure in which a small specific gravity of air is injected into a solid having a large specific gravity such as a buoy, etc. It can be used according to the needs of design concept.

The substance that can be decomposed or dissolved by seawater or freshwater of fishery is not particularly limited to the starch composition of the present embodiment, and may be used alone or in combination with water-soluble synthetic resins, food materials, biodegradable resins, paper, wood chips, and the like. do. Specifically, PVA, mantriose, corn starch, gelatin, polylactic acid, etc. can be illustrated. Moreover, you may use the gel material formed by gelling met, agar, tamarin seed gum, etc.

In addition, the bait main body 3 can be used together with picking means, such as fish meal and a light reflection member, as needed for a design concept.

The weight member 4 is for reaching the predetermined depth of the bait main body 3, for example, the overall length is formed in a cylindrical shape of about 70 mm. The outer diameter of the weight member 4 is slightly larger than the inner diameter of the case 2. One end of the weight member 4 shown in the upper right of FIG. 1 is an insertion portion 4a into the case 2, and is attached to the mounting portion 2a of the case 2 by fitting or the like. . Moreover, the other end shown in the lower left of FIG. 1 of the weight member 4 is made into the base 4b, and is exposed to the exterior. Further, a plurality of grooves 6 extending in the longitudinal direction in the axial direction are arranged on the outer circumference of the weight member 4 concentrically about the axis. These grooves 6 are formed along the axial direction from the tip of the insertion portion 4a to the central portion of the base 4b.

The gap between the grooves 6 and the inner hole of the case formed by the internal space 7 between the case 2 of the present embodiment and the mutually facing surface between the weight member 4 and the flow of speculation. (8) is comprised.

In addition, the shape of the weight member 4 is not particularly limited to the shape of the present embodiment, and the base 4b has various shapes such as a multi-rod shape having a diameter larger than that of the insertion portion 4a. Optionally available.

As a raw material of the weight member 4, a water-soluble resin composition and a high specific gravity material-containing soluble composition are used in this embodiment.

As said high specific gravity material containing soluble composition, the thing of the range of barium sulfate / PVA = 95 / 5-30 / 70, for example, the thing of barium sulfate / PVA = 85 / 15-75 / 25 can be illustrated, for example.

The high specific gravity material used in the high specific gravity material-containing soluble composition is not particularly limited to the barium sulfur of the present embodiment, but may be used in chemical substances such as titanium oxide, zinc oxide, zircon oxide, magnesium oxide, molybdenum disulfide, and natural materials such as gravel. It can be used depending on the needs of the design concept.

Moreover, it is good also as a structure which gives the case 2 the function of the weight member 4. For example, the structure which makes the case 2 into a user cylinder shape with a water-soluble material can be illustrated. In this case, the material of the case 2 is made of a water-soluble or biodegradable material having a specific gravity that is heavier than seawater or freshwater, or a heavier substance such as gravel is mixed or mixed to facilitate reaching a deeper depth. It may be attached to the outer periphery of 2). In the case where the function of the weight member 4 is imparted to the case 2, a single or a plurality of through holes penetrating in the thickness direction on the outer surface of the case 2 may be formed as liquid introduction means.

The stopper member 5 has a thickness of, for example, about 10 mm in diameter and about 5 mm in thickness in order to prevent the bait body 3 housed inside the case 2 from protruding from the case 2 unnecessarily. It is formed in thick substantially disk shape. The plug member 5 has a plug mounting portion of the inner hole of the case 2 such that its axial direction is orthogonal to the axis of the case 2, that is, both end faces thereof follow the axis of the case 2. It is attached to (2b) by fitting, etc., The communication space 9 along the axial direction of the case 2 is formed between the both end surfaces of the plug member 5, and the inner hole of the case 2.
