Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bullet for a play gun. More particularly, the present invention relates to bullets for air game guns.

[Prior Art and Problems Thereof] Generally, a plastic sphere called a so-called BB bullet is used as a bullet for a game gun such as a gas gun or an air gun.

However, the hardness of the BB bullet is large, and if it accidentally hits a person, the impact at the time of hitting is large, so there is a problem in safety, and almost no bullet marks are left on the impacted part of the object. Since it is not there, it is inferior to the actual feeling of shooting.

Therefore, as a bullet that scatters or bursts at the time of impact and can color the impacted part of the object, in recent years, the so-called paint bullet, in which the inside of the bullet is hollow and a colorant such as paint or paint is injected So-called marking bullets, in which the surface of bullets and bullets are coated with a coloring agent, have been developed.

Recently, a seamless soft capsule (seamless capsule) manufacturing method is applied to form a gelatin film into a spherical shape, and oils and fats and oil-soluble coloring agents are used as the content liquid. Has been done. Since this soft bullet is softer than a plastic bullet,
Highly safe as a bullet for a play gun, because the spherical coating ruptures at the point of impact and the colored oil and fat inside the capsule scatters, coloring the point of impact on the target. Is. However, since the content liquid uses oils and fats, it has a light elasticity, and since the pigments are oil-soluble, they do not fall off even if the coloring is washed with water or hot water. It is necessary to wash with an organic solvent. Further, since the soft bullet is lightweight, it lacks the linearity of the trajectory at the time of firing.

Furthermore, since the conventional commercially available seamless soft bullets are manufactured by the seamless capsule method, the coloring liquid used as the inner solution can be filled with fats and oils or oil-soluble dyes,
It was not possible to fill it with water or an aqueous base.

[Problems to be Solved by the Invention] Therefore, as a result of intensive research conducted by the present inventors in view of the above-mentioned problems of the prior art, the bullet shot by the subject bursts and the contents of the bullet Objects are scattered and the landing area of the object is easily colored, it is a true sphere and it is excellent in the linearity of the trajectory, and the bullet surface is softer than the BB bullet and it is also safe when hit and the colored area Found a bullet for a play gun that can be easily washed by wiping it gently with tissue paper or washing with water. It was also found that when a photosensitive dye or a pH indicator is used as a colorant, it becomes naturally colorless without washing due to neutralization by sunlight or carbon dioxide in the air.

By the way, as mentioned above, in the filler for soft bullets,
For linearity of the trajectory, it is preferable to use an aqueous base heavier than fats and oils and a water-soluble dye rather than an oil-soluble dye from the viewpoint of detergency. Therefore, the inventors of the present invention have conducted extensive studies as a capsule that can replace the seamless capsule described above, and found that a rotary soft capsule can be filled with a water-soluble base, and further, a water-soluble base such as polyethylene glycol or butylene glycol. When the spherical capsules are filled with a tar dye, a lake dye, a fluorescent paint, a filler containing a colorant such as a pigment or a pH indicator, the above-mentioned problems are found to be completely solved, and the present invention is provided. Has been completed.

[Means for Solving Problems] That is, according to the present invention, a soft capsule is filled with a filler comprising a water-soluble base and a water-soluble colorant, and the water-soluble base is polyethylene glycol, butylene glycol, polyethylene glycol. A mixture of water and water or a mixture of polyethylene glycol and ethyl alcohol or isopropyl alcohol, wherein the soft capsule is gelatin, agar, alginic acid, alginate, pullulan, carrageenan, farseran, cellulose derivative,
The present invention relates to a bullet for a play gun, which comprises one or a mixture of two or more kinds selected from tamarind gum, locust bean gum, guar gum and protein.

[Example] The bullet for a play gun of the present invention can be obtained by filling a soft capsule with a filler comprising a water-soluble base and a water-soluble colorant.

Examples of the water-soluble base include polyethylene glycol having a number average molecular weight of 200 to 1000, butylene glycol, a mixture of polyethylene glycol and water, or a mixture of polyethylene glycol and ethyl alcohol or isopropyl alcohol.

Examples of the water-soluble colorant include tar dyes Blue No. 1, Blue No. 2, Red No. 3, Red No. 231, and Daidai 207.
No. and other photosensitive dyes; phenolphthalein, thymol blue, cresol red, phenol red, bromothymol blue, and other pH indicators; curcumin, carminic acid, and other natural dyes. Among these, the photosensitive dyes are , It has the property of fading by light rays such as sunlight, and can naturally make the coloring of the landing site of the object colorless, and the pH indicator is colorless and neutralized by carbon dioxide in the air. Therefore, it can be used particularly preferably.

The amount of the water-soluble colorant used is preferably 0.01 to 10 parts by weight, more preferably 0.05 to 5 parts by weight, based on 100 parts by weight of the water-soluble base. If the amount used is less than 0.01 parts by weight, coloring will be insufficient, and if it exceeds 10 parts by weight, it will be expensive and the cleaning property may be poor.

Examples of the soft capsules include rotary-type seamed soft capsules, and as the raw materials of such soft capsules, gelatin, agar, alginic acid, alginate, pullulan, carrageenan, farseran, cellulose derivative, tamarind gum, locust bean gum,
Mention may be made of one or a mixture of two or more selected from guar gum and protein. As these additives, sorbit, glycerin, other polyhydric alcohols, caramel, mica, titanium, and water-soluble thickeners such as hydroxycellulose and carboxyvinyl polymer may be added. These additives improve the shape retention and destructibility of bullets, and improve the safety and game suitability required for game gun bullets.

In order to suppress the scattering of the filler when the bullet ruptures, it is better to increase the viscosity, and in the case of 2000 cP or more, it is good because a suitable scattering is obtained.

Although the strength of the film forming the soft capsule is smaller than that of the conventional bullet film made of synthetic resin, it has a shape-retaining property and an appropriate strength for enhancing safety on hit.

The size and shape of the soft capsule are arbitrary,
The size is usually 0.05 to 1 mm, though it is appropriately determined in consideration of the caliber of the play gun. The thickness of the capsule is adjusted so that it does not burst when a bullet is fired from the play gun, but bursts when it hits the target object, and varies depending on the size of the bullet and the bullet firing capability of the play gun. Therefore, it cannot be determined in a general way, but it is usually adjusted to be 0.05 to 1 mm.

The thus obtained bullet for a play gun of the present invention is a soft capsule (2) filled with a filling material (3) as shown in the schematic sectional view of FIG. Incidentally, in FIG. 1, (1) shows a bullet for a play gun of the present invention.

Next, the present invention will be described in detail based on examples, but the present invention is not limited to these examples.

Example 1 A filling (viscosity: 2500 cP) consisting of 60% by weight of polyethylene glycol (number average molecular weight: 400), 36% by weight of water, 3% by weight of carboxyvinyl polymer and 1% by weight of tar dye red No. 3 was placed in a rotary soft capsule ( (Soft capsule with two hemispheres made of gelatin joined, diameter: 6.0 mm)
To prepare a bullet for a play gun.

The weight of the obtained game gun bullet was 0.14 g.

Next, use this game gun bullet with an air gun (MGC, SWM45
When I shot it using 9) and hit the target, the bullet ruptured and attached to the target, but since the coloring material was contained in the filling, the landing site was clearly visible. .

Example 2 99.5% by weight of butylene glycol and tar dye blue 1
The same rotary soft capsule as used in Example 1 was filled with a filling material containing 0.5% by weight of No. 5 to prepare a bullet for a play gun.

The weight of the obtained game gun bullet was 0.13 g.

Next, this play gun bullet was fired using the same air gun as that used in Example 1 to hit the object, the bullet ruptured, adhered to the object, and dyed blue. However, after 5 hours in direct sunlight, the color faded to colorless and it was not necessary to wash.

Example 3 Polyethylene glycol (number average molecular weight: 200) 95% by weight, pH indicator (phenolphthalein) 2% by weight and
The same rotary soft capsule as that used in Example 1 was filled with a filling material (pH: 9 to 10) containing 3% by weight of a pH adjuster (sodium hydroxide) to prepare a bullet for a play gun.

The weight of the obtained game gun bullet was 0.13 g.

Next, this play gun bullet was fired using the same air gun as that used in Example 1 to hit the object, the bullet ruptured, adhered to the object, and became a light red color. It was dyed, but when left as it was, it became colorless after about 40 minutes and it was not necessary to wash.

Next, an air gun fixed on the table (MGC, product number: SW
I filled the bullets obtained in M459) and fired 50 times at a target 5m away, and counted the number of bullets that hit other than 30cm from the center of the target.

For comparison, a conventional soft bullet (weight 0.11 g) was used to shoot at the target in the same manner as above, and the number of bullets that hit the target other than 30 cm from the center was counted. . The above results are shown in Table 1.

As described above, since the weight of the game gun bullet of the present invention is 20% or more larger than that of the conventional seamless soft bullet, it can be seen that the bullet linearity is excellent.

[Effects of the Invention] As described above, the bullet for a play gun of the present invention bursts when it hits an object, the filler scatters, and the landing portion is colored, but compared to conventional BB bullets. Since it has the same volume and a large weight, it excels in linearity of the trajectory, and since the game gun bullet is flexible, it is highly safe when hitting a human body. Further, even if the bullet for a play gun of the present invention bursts and the filling material inside is scattered and the landing portion is colored, the colored portion can be easily wiped off with tissue paper or the like. For example, if it adheres to clothes, it can be easily washed with water.

In addition, when using a fluorescent paint as a water-soluble colorant, the landing site is clear even at night, and when using a photosensitive dye or a pH indicator, it does not need to be washed because it fades over time Produce an effect.
