A writing instrument having a body, a main reservoir containing ink and housed in said body, a writing head projecting from the front part of said body, and a capillary connector for transferring ink from the main reservoir to the writing head. The instrument has an auxiliary reservoir containing an ink carrier liquid, and an actuator for releasing said liquid from the auxiliary reservoir so that said liquid flows into the main reservoir and expels the ink towards the connector. The carrier liquid contains the ink solvent, in particular water in the case of a water-based ink, and preferably contains all or any of the components of the ink in the main reservoir, whereby the original writing properties of the residual ink carried by the carrier liquid are preserved.
A writing instrument comprising a body, a main reservoir containing ink and housed in said body, a writing head projecting from a front part of said body, and a capillary connector for transferring ink from the main reservoir to the writing head, wherein said writing instrument also comprises an auxiliary reservoir containing an ink carrier liquid, and actuator means for releasing said liquid from the auxiliary reservoir so that said liquid flows into the main reservoir and expels the ink towards the connector, wherein the main reservoir and the auxiliary reservoir are both fibrous material reservoirs and wherein, upon operations of the actuator means, the auxiliary reservoir is displaced into contact with the main reservoir.
