US Patent:

62988417, Oct 9, 2001

Filed:

Jan 7, 2000

Appl. No.:

9/479201

Inventors:

Richard T. Cheng - Virginia Beach VA
James S. Cheng - Virginia Beach VA

International Classification:

F41B 1100

US Classification:

124 56

Abstract:

Light emitting rigid fracturable projectile-type marking ammunition are provided. The ammunition is a phosphorescent ball in the form of a spherical pellet or capsule that includes non-phosphorescent impact diffusing materials intimately admixed with phosphorescent materials. Non-phosphorescent pigments, fillers, and surfactants may also be included. The light emitting phosphorescent ball provides a luminous trail when discharged from the paintball gun and thus, may be used effectively in the dark.

Inventors:

Richard T. Cheng - Virginia Beach VA
James S. Cheng - Virginia Beach VA

International Classification:

F41B 1100

US Classification:

124 56

Abstract:

Light emitting rigid, fracturable projectile-type marking ammunition is disclosed. The marking ammunition is in the form of a phosphorescent paintball. An exciter is adaptable for use with paintball guns to excite the phosphorescent paintball to emit light. The exciter couples to the muzzle of a paintball gun. The light emitting paintball provides a luminous trail when discharged from the paintball gun. A paintball according to the instant invention comprises a spherical pellet or capsule defining an interior chamber, and a filler contained in the chamber. In one embodiment, the capsule is impregnated with a phosphorescent material. In an alternative embodiment, a phosphorescent material is mixed with the filler. The phosphorescent material absorbs light when exposed to a light source, and after the light source is removed, emits light. A paintball being discharged from a paintball gun enters the exciter.

F41B 1100

US Classification:

124 56

Abstract:

Light emitting rigid fracturable projectile-type marking ammunition and reusable resilient projectile-type ammunition are provided, along with kits of the ammunition with an exciter and optionally a paintball gun. The ammunition is a phosphorescent ball in the form of a spherical pellet or capsule that includes non-phosphorescent impact diffusing materials intimately admixed with phosphorescent materials. Non-phosphorescent pigments, fillers, and surfactants may also be included. The light emitting phosphorescent ball provides a luminous trail when discharged from the paintball gun and thus, may be used effectively in the dark.
