ABSTRACT:
An ink pen is provided with a hydrophobic membrane to control the leakage of ink. The ink pen has a vent, such as a bubble generator, to allow the ingress of air into the ink reservoir and thereby regulate the backpressure within the reservoir. The hydrophobic membrane which allows the flow of air but prevents the flow of ink is positioned within the vent to control leakage of ink from the ink pen through the vent.
