Abstract (en)

[origin: WO9737860A1] Described is an ink writing implement with a writing tip (1) at the front end and with a pressure-compensation system having annular chambers (13) of capillary dimensions, a capillary ink-feed channel (11) connected to the chambers, and an air-feed channel (16) connected to the surrounding atmosphere. The writing implement also includes a moulded element (3) in which the disc-shaped walls (12, 12') and the ink-feed channel are produced by injection moulding in a die mould with two halves having embedded stacks of metal plates to form the annular pressure-compensation chambers. The moulded element (3) has, extending longitudinally along it, a flat area (10, 10') which forms the ink-feed channel (11), and the mould-parting plane (25, 25') passes through this flat area.
