Liquid applicator

摘要

A liquid applicator using a roller which is effectively prevented from being disengaged from the housing thereof. The liquid applicator provides very smooth flow of ink from the initial touch of drawing without generating a scratchy effect. The improved liquid applicator introduces a roller in place of a conventional ball of a ball pen. The roller is a hollow structure. A roller-storing portion is defined by a surface having stepped tapered portions. The liquid applicator incorporates a relay core. The relay core comes into contact with the roller in the roller-storing portion to press the roller in the direction of an aperture on the roller-storing portion.
