Abstract
A brushless white-out correcting fluid applicator for use in applying white-out fluid to paper without using a brush. The white-out fluid is a suspension including a substantial proportion of white or substantially white particles, such as titanium dioxide, or other color particles. The applicator includes a wear-resistant, porous tip and a regulator between the tip and a reservoir. The regulator may be formed of foam material, and the tip may be of sturdy porous plastic. The size of the pores in the tip and regulator are large enough so that they do not become clogged with particles in the white-out fluid. The regulator prevents the tip from dripping by regulating the rate at which fluid can leave the reservoir. The size of the pores adjacent the reservoir may be different than the size of the pores and passageways adjacent the tip. The applicator may be provided with an air-tight cap to avoid drying out between uses. Alternative embodiments of the applicator include a foam tip with a nylon mesh outer covering for wear resistance; and an internal, pressure actuated valve may be included to regulate the flow of the white-out suspension to the tip.
