Counterweight projectile
The present invention provides a counterweight projectile having an upper hemispherical shell and a lower hemispherical shell and each having a plurality of grooves on the inner surface thereof, wherein a hollow space is formed in the combined upper and lower hemispherical shells used to contain a spherical content. The counterweight projectile includes a spherical spring accommodated in the hollow space. The spherical spring is in a shape of a plurality of coils wound along the inner surfaces of the upper and lower hemispherical shells, and is completely supported and held on the inner surfaces of the hemispherical shells. After ejecting, the counterweight projectile which has a matching weight to shoot forward, stably, straight and evenly to an impact point, after contacting the impact point, the spherical spring is squeezed and restored to explode the upper and lower hemispherical shells, and increases the explosion and spread of the spherical content.
1 . A counterweight projectile having an upper hemispherical shell and a lower hemispherical shell combined to form a sphere, each of the upper and lower hemispherical shells having a plurality of grooves on an inner surface thereof, wherein a hollow space is formed between the upper and lower hemispherical shells to contain a content, wherein the counterweight projectile comprises a spherical spring accommodated in the hollow space of the upper and lower hemispherical shells, wherein the spherical spring is in a shape of a plurality of coils wound along the inner surfaces of the upper and lower hemispherical shells, and is completely supported and held on the inner surfaces of the upper and lower hemispherical shells, wherein after being launched, the counterweight projectile is configured to shoot forward, stably, straight and evenly to an impact point, and after contacting the impact point, the spherical spring is squeezed and configured to be restored to explode the upper and lower hemispherical shells thereby spreading the content.
2 . The counterweight projectile, as recited in claim 1 , wherein the content is selected from the group consisting of chili powder, talcum powder, and lacquer liquid.
