Liquid-ink writing instrument having a reservoir fitted with a system to prevent loss of priming

摘要

A writing instrument is provided, including a writing tip, a reservoir containing a liquid ink, and a capillary transfer rod extending from a first end to a second end of the reservoir. The capillary transfer rod transfers the liquid ink from the reservoir to the writing tip. A capillary element having an orifice is slidably mounted around the capillary transfer rod so as to move freely in the reservoir. An outside edge of the capillary element comes into the immediate vicinity of an inside wall of the reservoir in such a manner that the capillary element comes substantially flush with an inside wall of the reservoir as it slides along the transfer rod.
