Abstract
A device for applying a fluid, notably a writing pen or cosmetic pencil, includes a tubular shaft, a fluid container that is positioned therein, a tip, and a conducting system for the fluid. The container ensures constant pressure equalization with the atmosphere by having its front and rear ends each being fluidically connected to the atmosphere. At the rear end of the container a ventilation opening is positioned. The ventilation opening opens into the container interior containing the fluid and is sealed by a semi-permeable membrane.
