摘要： 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.
摘要翻译：一种用于在不使用刷子的情况下将白色液体施加到纸上的无刷白色校正流体施加器。白色流体是包括相当大比例的白色或基本上白色的颗粒的悬浮液，例如二氧化钛或其它着色颗粒。涂抹器包括耐磨多孔尖端和尖端与贮存器之间的调节器。调节器可以由泡沫材料形成，并且尖端可以是坚固的多孔塑料。尖端和调节器中的孔的尺寸足够大，使得它们不会被白色流体中的颗粒阻塞。调节器通过调节流体可以离开储存器的速率来防止尖端滴落。与储存器相邻的孔的尺寸可以不同于邻近尖端的孔和通道的尺寸。施加器可以设置有气密帽，以避免在使用之间干燥。涂抹器的替代实施例包括具有用于耐磨性的尼龙网外覆盖层的泡沫顶端; 并且可以包括内部的压力致动阀以调节白色悬浮液到尖端的流动。
