ABSTRACT:
A fountain pen includes a fountain pen barrel, an ink tube fixed inside the pen barrel, a stopper means fixed inside said pen barrel to hold the ink tube in place, and a fountain pen head joined to the other end. A pressing force applied to an urging means moves the ink tube in an axial direction towards a writing core which guides ink from the ink tube in a capillary flow. Axial movement enables the stopper means to generate a contracting force on the ink tube to increase the releasing pressure of the ink. Excess ink absorbed by the writing core permeates an ink absorbent member disposed inside the fountain pen head to prevent leakage of excess ink.
