ABSTRACT:
The ink supply system of a fountain pen which defines a longitudinal path of ink flow from a reservoir in the pen barrel to a writing point projecting from the barrel includes an ink feeding member defining therein one portion of the ink path contiguously adjacent the writing point and a flow controlling member defining another portion of the path which connects the ink feeding member to the reservoir. The latter portion of the ink path is elongated and has an effective flow section smaller than the flow section in the feeding member.
