Patent

CA 2493281

The writing instrument (1) comprises a body (2), a main reservoir (3) containing ink and housed in said body (2), a writing head (5) projecting from the front part (2a) of said body (2), and a capillary connector (4) for transferring ink from the main reservoir (3) to the writing head (5). It further comprises an auxiliary reservoir (6) containing an ink carrier liquid, and actuator means (7) for releasing said liquid from the auxiliary reservoir (6) so that said liquid flows into the main reservoir (3) and expels the ink towards the connector (4). 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 (3), whereby the original writing properties of the residual ink carried by the carrier liquid are preserved.

L'article d'écriture (1) comprend un corps (2), un réservoir principal (3) dans lequel l'encre est emprisonnée et qui est logé dans ledit corps (2), une tête d'écriture (5) débouchant en dehors de la partie avant (2a) dudit corps (2) et un connecteur capillaire (4) assurant le transfert de l'encre depuis le réservoir principal (3) jusque la tête d'écriture (5). De plus il comporte un réservoir auxiliaire (6), contenant un liquide véhiculeur de ladite encre et des moyens d'actionnement (7) permettant de libérer ledit liquide du réservoir auxiliaire (6) en sorte qu'il se déplace dans le réservoir principal (3) et repousse l'encre vers le connecteur (4). Le liquide véhiculeur contient le solvant de l'encre, notamment de l'eau lorsqu'il s'agit d'une encre aqueuse, et de préférence tout ou partie des composants de l'encre du réservoir principal (3) permettant à l'encre résiduelle, entraînée par le liquide véhiculeur, de conserver ses propriété initiales d'écriture.
