摘要
Writing element for felt tip pens consists of a small pipe writing point, a front section which can be screwed into the pen holder shaft and a marking ink store carried by that section. At least the drawing nib (10) and the marking ink storage container (14) are produced in one piece by an extrusion process. The drawing nib (10) is separated from ventilation channels. The container is filled with colouring ink within exclusion of air. The ink column is closed off by a stopper (32) in the form of a silicon follower which provides a constant closure. The integral unit also includes the front section (12).
