ABSTRACT:
A nib for a marking pen which has at least one, preferably two, grooves or valleys formed in the sides thereof which intersect a projection on an inside surface of the marking pen barrel for securing the nib within the marking pen. In the preferred embodiment, the nib is formed from flat strips of stock by forming two grooves down the center of the strip and subsequently cutting parallelogram-shaped nibs from the strip. When the nib is assembled to the pen, the projection intersects a first one of the grooves at a front of the nib, and intersects the second one of the grooves at the back of the nib. Advantageously, this construction provides for stable orientation of the nib within the pen and facile assembly, without the need for pinning or die cutting an irregular shape. In addition, the method of forming the nib allows for high throughput production.
