Abstract (en)
The implement comprises a rigid body (2) made from a compact block of a porous material with open pores which also acts as a reservoir for ink. The block is enclosed in an outer impermeable casing (3) apart from its tip (5), and the block itself of made from micro-balls of a thermoplastic material, stuck together by thermo-adhesion, while its pointed tip is compact and hydrophilic, and of a predetermined hardness. The compact ink block can be made from adjacent portions of hydrophilic and water repellent materials, the former being traversed by pressure balancing channels.
