Title:
PRESSURIZED WRITING INSTRUMENT EMPLOYING A COMPRESSIBLE PISTON MEMBER
Document Type and Number:
WIPO Patent Application WO2001065970
Kind Code:
A8
Abstract:
A pressurized writing device comprising an ink tube (12) having a first end (18) and second end (20), a writing tip (22) at the first end, an end plug (30) at the second end and a pressurizing system (24). The pressurizing system applies a force to a writing medium (14) in the ink tube to force the writing medium out the writing tip. The pressurization system includes a compressible ink driving member (28). The compressibility of the ink-driving member assures a secure seal of the writing medium in the ink tube. Additionally, the compressibility permits the ink-driving member to wipe ink off the interior surface of the link tube as ink is expended.
