Writing implement, esp. ball-point pen with adjusting device to propel geometrical body out of pen housing and reveal e.g. tw0/three-dimensional advertising

摘要

The ball point pen has a housing (1) containing a refill (2), and an adjusting device (6). This moves a part-length of the refill out of the housing, so that a geometrical body (9) emerges partially or completely from the housing. After this, a two/three-dimension picture, writing, or a combination, become visible. Adjusting device and refill an be retracted.
