An applicator for uniformly dispensing liquid such as ink. The applicator is composed of a flexible supply bottle with a porous plastic applicator disc attached to one end. The porous plastic applicator forms a tight seal with the ink supply bottle. The applicator disc is preferably composed of sintered porous polyethylene having an average pore size of between about 35 to 50 microns in diameter with pores occupying between about 40 to 50 percent of the applicator volume. When the bottle is squeezed, ink is forced out of the bottle through the porous applicator disc; and when the bottle is released, ink trapped within the applicator disc interior returns to the bottle preventing clogging of the applicator disc. The applicator is secured to the ink supply bottle by engagement between an annular flange at the bottle's mouth and a circumferential groove in the applicator.
