ABSTRACT:
To screw the writing tip in and out of the instrument shaft of a writing or drawing instrument, the cap has been used as a screwing tool. The cap is usually fabricated with a many-sided receiving bore for this purpose as an extension of its bore, which can be placed onto the writing tip after the cap has been turned around. As a result, the cap is relatively long. The writing or drawing instrument of the present invention in contrast, has a cap of standard length. A many-sided receiving bore which is to be placed on the writing tip, in order to be able to screw it in or out, is formed, in part, by the clip of the cap, and in part by the wall of cap in the region where the clip is connected to the cap.
