  • Patent number: 8813736
    Abstract: A sport blow gun is a blow gun which is a tube with a bore, a loading end and a muzzle end. A projectile is inserted into the loading end and blown out the muzzle end by the user's breath. The main tube features a safety device which prevents a projectile from falling out of the tube or being inhaled. One type of projectile fired from the blow gun is a dart which is usually comprised of foam or soft material, and may also be made out of a material which causes relatively little resistance as it passes through the bore, yielding higher velocity. The projectile may also be coated with a coating which reduces resistance with the bore. Projectiles may also be modified in form for aerodynamic efficiency.
