Abstract

The present invention relates to the field of paintball bullets designed with the ability to be destroyed by hitting the target, as well as with the ability to retrieve the bullets, which has a quadrilateral design symmetrical to the central cylinder. The pellets are made of calcium carbonate and polyethylene, which are environmentally friendly and can be used at a temperature of -20 to + 50 degrees Celsius and due to the aerodynamic properties of the bullet, it is used directly for the length of the bullet and the throwing of the bullet, and the passage of the launch path.

Description

Recoverable four-sided calcium carbonate paintball

MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING (F)- WEAPONS (F41)- WEAPONS FOR PROJECTING MISSILES WITHOUT USE OF EXPLOSIVE OR COMBUSTIBLE PROPELLANT CHARGE; WEAPONS NOT OTHERWISE PROVIDED (F41B) - compressed-gas guns, e.g. air guns; Steam guns (F41B 11/00) - TARGETS; TARGET RANGES; BULLET CATCHERS (F41J) - Bullet catchers (F41J 13/00) and or indicating the distance by which a bullet misses the target (F41J 5/12)

The bullets used in paintball are made in such a way that they are destroyed by a collision with a person and the paint inside it is spread on the collision site, which will confirm the collision of the bullet with the person. These pellets are spherical gelatin capsules consisting of materials such as polyethylene glycol, non-toxic substances, and soluble in water and paint. Paintballs are made from materials, some of which are found in food but have an unpleasant taste because they cause dry mouth. The use of polyethylene glycol (laxative) inside the pellets causes gastrointestinal upset in people who eat the color of these pellets. Therefore, these bullets should be kept out of the reach of children.

The original paintballs were made of glass and filled with inedible oil paints, and were used to mark trees and animals. Modern paintballs should be easy to remove from most clothing. The color of the shell does not necessarily indicate the color of the liquid inside. Most paintball bullets and markers are described as 0.68 calibers (17.3 mm), but many factors affect the exact dimensions. The size of paintball bullets and rifle barrels varies from 0.67 to 0.71 caliber (17 mm to 18 mm).

Paintballs are seldom completely round and are very sensitive to heat and moisture. A hot or humid day may cause the bullet to swell or become deformed. Therefore, these pellets should be kept away from sunlight and moisture. The gelatin shell of the paintball is designed to be broken by the impact. There are several types of paintballs, including glowing balls for night use, scented paintballs with special formulas for winter games, and more. Another disadvantage of colored paintballs when the bullet falls to the ground is that water collected on the ground or groundwater may swell the paintball, which can cause the shell to swell and block the tube. A marker that disrupts the function of the gun.

In general, paintball balls are produced at higher prices, subject to quality production processes and below the standard, with a more compatible size and shape, which is important for the accuracy of the balls. Suitable bullets have thin shells that break more often due to the impact of the bullet and the liquid inside is easily recognizable. Although it is theoretically possible to freeze water-based colored paintballs, polyethylene glycol additives dramatically reduce the freezing point of the compound, and it is unlikely that by freezing, the bullet will become more difficult than something else. Become an ordinary paintball bullet. When the environment is very cold, there is a dimple in the shell of the paintball, which reduces the accuracy of the bullet and makes the shell more fragile. Therefore, some professional ball speed teams cool their balls in the freezer to make the bullet more fragile.

US SWAT teams often use paintball-like bullets known as pepper balls, which are filled with Oleoresin Capsicum, the active ingredient in pepper spray, and is known as a non-lethal disabling method. Pepper bullets are fired faster to be safe (more than 350 feet per second (110 meters per second)). Pepper bullets can be fired from most paintball guns.

In recent years, HydroTec Bullets has introduced a new paintball that is made of corn husk and contains up to 98% water. The shell of the bullet can withstand temperatures up to 120 degrees Fahrenheit (49 degrees Celsius). The above features, combined with a unique manufacturing process, make a more stable paintball ball. But the problems with this type of bullet are the high fragility of the bullet during transport and operation or this type of bullet.

Reusable bullets are an alternative to regular paintballs. "Reballs" are one of the most widely used bullets in this category, which are made of flexible plastics. Most reusable paintballs are the same size as regular paintballs that do not contain paint. Since these bullets do not open to leave a color mark on players, they are practical for indoor locations where the accumulation of paint due to the bullet breaking can be problematic. But this form of paintball, since it leaves no color mark, allows players to cheat easily. A Reball bullet is much more expensive than a paintball bullet, but because it can be cleaned and reused many times, it is potentially less expensive for users. Some paintball parks have added dedicated reball fields. The initial use of Reballs, as originally intended by the developers, is considered a practical aid for teams wishing to save money by using reusable bullets.

Other manufacturers have produced similar products, such as the V-Ball, a reusable velvet-like product. Reballs are used because of their inability to break at a slower rate. For example, a typical paintball bullet is usually fired at a speed of fewer than 300 feet per second (91 meters per second), while a Reball is used at a speed of nearly 240 feet per second (73 meters per second).

About foreign inventions, studies on paintball balls are often used on fillers inside paintball balls and shell materials. like the:

Oil and polyethylene glycol fill material for use in paintball shells

United States Patent 8920918

A fill material is for use within a closed interior chamber of a gelatin paintball capsule. The fill material includes a polyethylene glycol and an oil. Each one of the polyethylene glycol and the oil is present in a respective amount that is substantially less than about 90% by weight of the fill material.

The fill material additionally includes at least a first additive that is selected from the group consisting of an emulsifier, a dye, a density agent, a thickener, and a surfactant. Preferably, a starch may be used as the density agent, as the emulsifier, and/or as the thickener. Suitable starches may include corn starch, rice starch, potato starch, modified starch, and combinations thereof, among others. In 2014, the new fillers include polyethylene glycol, oils and additives such as surfactants, emulsifiers, rice starches, groundnuts and corn, which are different from my design.

Water based paintball and method for fabricating water based paintballs

United States Patent 8479656

A paintball includes first and second half shell portions, each with a recess that can hold liquid containing dyes or other marking pigments. The liquid in the second half shell portion is relatively viscous, or becomes so after being placed in the second shell portion. The second shell portion can then be inverted and the liquid will stay within it. Neither shell portion includes a barrier to hold the liquids in place. The second half shell portion can then be placed on and joined with the first half shell portion to form a paintball. In 2013, paintball balls with a two-layer shell were introduced, in which different compounds are placed in two layers and mixed after being hit, which is different in appearance from the servant design.

Phosphorescent paintballs that glow in the dark

United States Patent Application 20070054762

By using the glo-stick formulas also known as light-sticks and the assortment of luminescence bright colors like. Red, Yellow, Green, Violet, Orange, Blue, in these paintless paintballs it will make playing in the dark or the day light more enjoyable for the sportsman and woman and children everywhere. These three chemical compounds are all listed as non-toxic. Hydrogen peroxide 2.50 ml. Phenyl oxalate ester 1.25 ml. And the Fluorescent dye 1.25 ml. The gelatin capsule in a ball or a ball in a ball can be used, in any high power paintball air gun. Caliber 0.68 to activate them, simply squeeze the paintball with your thumb and forefinger.

Over the two gelatin interior posts supporting the center capsule or ball this will rupture that center capsule or ball, this start's the premixing process now your ready to load for the dusk to dawn paintball war games sport. Have fun with it and, enjoy the assortment luminescence bright colors. In 2005, three non-toxic compounds of hydrogen peroxide, phenyl oxalate ester and fluorescent paint were used to make bright paintballs for use in dark environments. In this design, the ingredients and the environment of use are different.

Paintballs containing paint used for paintball competitions have several technical and environmental drawbacks. These pellets are very fragile due to having a thin and gelatinous shell during transport and if broken inside the package, they will destroy other bullets. In the present invention, the design of paintball bullets in the form of a cylinder in the center and four quarters of a sphere encloses the cylinder. This design also creates the appropriate aerodynamic properties to maintain the range of the bullet and the launch of the bullet and the passage of the launch path directly. On the other hand, the bullets of the present invention are a combination of calcium carbonate and polyethylene, which due to the use of a high percentage of calcium carbonate in the composition, these pellets are environmentally friendly. They will also be recyclable after being used and destroyed by hitting the target.

Paintballs containing paint used for paintball competitions have several technical and environmental drawbacks. These pellets are very fragile due to having a thin and gelatinous shell during transport, and if they are broken inside the package, they will destroy other bullets. Also, the paint in paintballs, if used on natural grass fields, which are the main origin of paintball competitions, will eventually cause grass destruction and soil erosion. Also, the use of polyethylene glycol (laxative) inside the pellets causes gastrointestinal upset in people who accidentally eat the color of these pellets.

Therefore, these bullets should be kept out of the reach of children. On the other hand, when the competition or training environment is very cold, a hole is created in the shell of the paintball, which reduces the accuracy of the bullet and also makes the shell more fragile. Paintballs are very sensitive to heat and moisture. A hot or humid day may cause the bullet to swell or become deformed. Another disadvantage of colored paintballs when the bullet falls to the ground is that water collected on the ground or groundwater may swell the paintball, which can cause the shell to swell and block the tube. In recent years, new training bullets that do not have color have been introduced, such as ribs.

These bullets are made of flexible plastic that can be reused, but this type of bullet can not be destroyed and causes the challenge of cheating during training. Given the above, it is important to build bullets that can minimize the environmental and technical problems of previous bullets. The bullets of the present invention, because they contain a large amount of calcium carbonate, are environmentally friendly pellets that can be recycled after use and destruction by hitting the target.

Solution of problem

To make the bullets of the present invention, first, a suitable mold of these bullets was prepared. Metal molds are made in four pieces to make it easier for the bullets to come out. According to , the design inside the molds is cylindrical in the center (2) and four quadrants (1) around this cylinder. Overview and side views of paintball bullets are shown in Figures 2 and 3. One of the main purposes of designing paintball bullets of the present invention is to create the ability to easily destroy the bullet by hitting the target for this purpose, as shown in Figures 1-3, the common surface of four quadrants (1) with a small central cylinder (2) is considered. Also, the symmetry considered in this design creates a suitable aerodynamic property to maintain the length of the bullet and the launch of the bullet, and the passage of the launch path directly.

Another purpose of the present invention is to design an environmentally friendly paintball that uses a combination of calcium carbonate and polyethylene. After designing and manufacturing the molds, to fill the molds and make the pellets, calcium carbonate and polyethylene are mixed at a temperature of 60 ° C and poured into the designed mold. The injection of the desired compound into the mold was continued for 1-2 minutes at a temperature of 60-80 ° C to fill the molds. After cooling the mold and forming pellets, after final quality control, they are sent for packaging. . Due to the use of the above compound and the stability of this compound from a temperature of -20 ° C to + 50 ° C, the bullets of the invention can be used in a wider temperature of -20 to +50 ° C Which includes a higher temperature range than previous bullets.

Also, due to the use of a combination of calcium carbonate and polyethylene, the pellets can be recovered after consumption and destruction. Destruction pellets are collected and after melting and poured into molds for molding.
