Abstract

This invention relates to a writing tool for correction of misspelled words or a writing utensil such as a ball-point pen, in which air in a cap is pressurized in a process of pushing the cap onto and mounting the cap on an extremity end and the compressed air is forced into a liquid tank through an end of a tip to provide pressurization within the liquid tank. A distance from an opening end surface of a cap to an inner bottom portion of the cap is defined with respect to a distance from an end of a tip to near a cap loading base end of an extremity end. A resilient member is mounted on an outer periphery of the extremity end or in the cap for pushing back the cap to a normal mount position relative to the extremity end by releasing a pushing operation after the cap is pushed near the cap mounting base end. The cap can be automatically pushed back from the cap mounting base end to the normal mount position of the extremity end by means of the elastic member.
