Angle-adjustable, gravity flow ink refill and pen

摘要

An angle-adjustable, gravity flow ink refill and pen, each comprising of at least one bendable portion along its length. The bendable portion acts as a concertina-type hinge to allow both the pen and refill to bend to an angle and maintain the bend imparted to it. In a preferred embodiment, the refill is flexible in structure (full or partial) and the pen having a crimped corrugated bendable portion. In an alternate embodiment, intertwined helical wires form the bendable portion for the pen, the refill or both to maintain the angle bent. Alternatively a flexible gooseneck tube is used for the bendable portion of the pen. The pen writes normally on flat surfaces and on inclined surfaces, the rear end of the pen is bent forward such that the rear is pointed upwards towards the sky. This allows ink to flow towards the tip via gravity and facilitate consistent delivery of ink at multiple writing angles.

主权项

1. A bendable, gravity flow writing tool having a body, and an ink refill contained therein; said body having an open tip end and a resiliently bendable section configured so as to maintain any given bend imparted to it; said ink refill being generally elongated, and having a nib at one end, and a flexible, resiliently bendable segment located above said nib and aligned with said bendable section of said body.
