摘要
The pen is designed for writing with a liquid ink. It has a holder, a liquid tank inside the holder and a writing point at the front end of the holder connected by channels or small pipes with the tank. At least one part of the walls (8,9) of the tank (7) are flexible and give in the length direction of the holder (12) in the direction towards the writing point (1). To ensure that the elastic flexible walls (8,9) compensate for the liquid used up by automatically adjusting in the direction towards the writing point (1), the liquid tank (7) is connected to the atmosphere on its outside.
