Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a baiting tool for baiting work to attract prey during rock fishing, embankment fishing, etc.

More specifically, the present invention relates to a bait-catching tool whose gripping hand is made of a thermoplastic resin that softens at low temperatures, and which can be shaped to fit the shape and size of the operator's hand.

[Prior art] In recent years, fishing as a hobby and pastime has become popular.
A variety of tools have been developed to meet various needs, and material manufacturers are particularly interested in this field as an application field for new materials.

In fishing, especially rock fishing and embankment fishing, it is common to scatter bait around the fishing spot at regular intervals in order to attract prey within the reach of the fishing rod. To do this baiting, you may grasp a chunk of bait with your bare hands and throw it far away, but throwing it with your bare hands not only means that the distance the bait you throw is short, but it also requires that the bait has solidified to a certain extent. It's hard to throw unless you're in good shape. However, solidified bait is not suitable for the purpose of baiting, and usually the frozen bait is dissolved with water to form a slurry, which is then placed in the container of the baiting tool, and baiting is carried out by sprinkling water.

Furthermore, since bare hands can get dirty with bait, a baiting tool commonly called a "ladle" is widely used for baiting. If this is used, even the slurry-like bait can be spread far and wide as described above.

This conventional baiting tool has a metal handle with a length of 30 to 50 cm, a grip made of a PVC resin pipe with a diameter of 1 to 2 cm, and a hemispherical or long hemispherical shape at the tip of the handle. A bowl with a capacity of 100 to 500 ml is attached.

The baiting operation is carried out by filling the container of this bowl with bait, grasping the handle, and throwing it far away.

[Problems to be solved by the invention] However, when working with this bait-spreading tool, there are the following problems.

a. The surface of the handle made of pipes such as vinyl chloride is smooth, so your hand may slip and the handle may rotate in your hand.

b If your hand slips, you may end up throwing away the bait at the moment you throw the bait.

c It is difficult for the person doing the baiting work to set the angle, direction, etc. according to the throwing method, and the bait may not be thrown in the desired direction.

d When baiting in the dark at night, it is difficult to tell the front and back of the dipper and the direction.

In order to solve these problems, for example, the surface of the handle can be given unevenness or knurling, or it can be given a finger shape that fits perfectly to the grip of the hand. Ru.

However, people's hands vary in size, and some people throw with a side throw or an underthrow, and some people are right-handed while others are left-handed. Therefore, even if finger shapes etc. are uniformly applied, they are often not created.

In view of this situation, the inventors of the present invention have completed the present invention after intensive study.

[Structure of the invention] That is, the invention is "a baiting tool characterized by having a handle made of polycaprolactone resin having a softening temperature of 60 to 80°C."

The key point of this invention is that even among thermoplastic resins,
Polycaprolactone resin, which has a softening temperature of 80℃ and can maintain its softened state at around 40℃, which is safe for the human body, is attached as a handle, and bait operators, that is, individual fishing enthusiasts, can use it with their hands. The reason is that it is possible to give a finger shape that suits the size and method of throwing.

Figure 1 shows the bait scattering tool of the present invention, 1-
1 is a gripping hand made of thermoplastic resin that softens in a temperature range safe for the human body, 2-2 is a gripping hand 1-1
The finger shape given to 3-3 is a container part into which bait is put. Vinyl chloride resin, which is used as the grip of conventional bait-catching tools, is also a thermoplastic resin, but it has a softening point of 150 to 200 degrees Celsius, and cannot be easily molded by amateurs.

It is possible to soften the material with a gas heater and mold it into a shape that fits your hand, but there is a risk of getting burned, and various measures must be taken to prevent burns. Work becomes complicated.

On the other hand, if the resin of the present invention has a softening temperature of 60 to 80 degrees Celsius and can maintain its softened state to around 40 degrees Celsius, which does not pose a risk of burns to the human body, it can be easily After being softened using 80℃ hot water, the material is cooled down to around 40℃, which poses no risk of burns to the human body, allowing it to be molded into a finger shape that fits the human hand.

Polycaprolactone resin is a material that has a softening temperature of 60 to 80°C and can maintain its softened state at around 40°C, which is safe for the human body.

This polycaprolactone resin is a crystalline resin obtained by polymerizing the monomer ε-caprolactone, and the degree of polymerization, that is, the molecular weight, can be easily adjusted, and as a result, the softening point can be easily set.

The molecular weight of a resin that has a softening temperature of 60 to 80°C and can maintain its softened state to around 40°C, which is safe for the human body, is 6,000 to 200,000. This is because if the molecular weight is less than 6,000, mechanical strength is insufficient, and on the other hand, those with a molecular weight of more than 200,000 are not manufactured industrially.

If this softening point is lower than 60°C, it may naturally deform during high temperatures in summer, so 60°C can be said to be the lower limit softening temperature.

Furthermore, if the temperature exceeds 80°C, it cannot be softened at bathing temperature when forming a finger shape, so this can be said to be the upper limit temperature.

The handle, which is made of resin that softens at 60 to 80°C and can maintain its softened state up to around 40°C, which is safe for the human body, may be rod-shaped, pipe-shaped, or have another material inserted in the center. It may also be a composite structure.

[Effects of the Invention] The baiting tool having a handle made of thermoplastic resin according to the present invention has the following advantages.

a. It is possible to give a finger shape that suits each person's hand size and throwing style.

b This can prevent slipping.

c Even if a finger shape is once applied, it can be corrected later.

d Even at night and in the dark, there is a sway, so you can spread bait smoothly just by touching it without checking with your eyes.
