Disposeable writing implement used in horizontal writing arms - has ink container and inserted writing tip

摘要

The implement consists of an ink storage container (1) and an inserted synthetic fibre- or lamelle tip (6). The tip has a sealed, welded filling aperture, and a ventilation aperture (4), which is sealed until use. Thin, rigid glass threads (9), which do not react to ink, are inserted into the container. The tips of the threads project into a small chamber (8) near the end of the writing tip (6), from which the tip is supplied with ink. A wall (10), projecting into the container, separates the ventilation aperture from the space, in which the threads are positioned in direction of ink flow.
