Ink containment system for an ink-jet pen |
摘要 |
A porous foam based ink containment system is provided with grooves defined in the exterior portion thereof, for storing ink, while preventing ink leakage from the ink-jet pen. The grooves provide passageways to allow air diffused throughout the ink and trapped air bubbles within the foam to expand and move to the atmosphere. An atmospheric vent is in fluid communication with at least one of the grooves.
