Abstract
Ballpoint pen cartridge, in which the ink 8 is under the almost constant pressure of gas in a space 7 above the ink 8. The cartridge is closed at the writing end by a ballpoint head 2, and the space 7 in the opposite direction is sealed by a valve stopper 4, 9 and thereafter an end stopper 3. The valve stopper 4, 9 has a thick section 4 corresponding to the inside diameter of the cartridge and a section 9 of smaller diameter. A bore 5 leads in an axial direction through the valve stopper 4, 9, and from this bore a radial bore 10 leads in a radial direction in the section 9. The bore 10 terminates at the side faces of the sections 9 and is covered by an elastic sleeve 6, which is drawn over the section 9. The required gas pressure is established in the space 7 by placing the ballpoint pen cartridge in a container, in which the required gas pressure for the space is generated, so that the gas flows through the ducts 5 and 10 under the sleeve 6 into the space 7. The sleeve 6 acts as non-return valve when the external pressure is reduced. <IMAGE>
