Title (EN) WRITING INSTRUMENTS AND ASSOCIATED METHODS
(FR) INSTRUMENT D'ÉCRITURE ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) Embodiments of the disclosure can include writing instruments, nibs for writing instruments, and methods of making the same. In one embodiment, the writing instrument includes a reservoir; an ink solution comprising a pigment, the ink solution being housed within the reservoir; a nib disposed at an end of the reservoir and plugging an opening of the reservoir such that the reservoir is closed, wherein a tip of the nib extends outside of the reservoir; and a filament extending within the reservoir, the filament being in fluid communication with a portion of the nib within the reservoir, such that the ink solution travels along the filament and through the nib, by capillary action, wherein the nib and filament are formed such that no more than 50 percent of the pigment present in the nib and filament flow into the reservoir outside of the nib and filament when the writing instrument is stored with the nib up for a period of one day.
(FR) Des modes de réalisation de l'invention peuvent comprendre des instruments d'écriture, des plumes pour instruments d'écriture, et des procédés de fabrication de ceux-ci. Selon un mode de réalisation, l'instrument d'écriture comprend un réservoir ; une solution d'encre comprenant un pigment, la solution d'encre étant logée à l'intérieur du réservoir ; une plume disposée à une première extrémité du réservoir et obturant une ouverture du réservoir de telle sorte que le réservoir est fermé, une pointe de la plume s'étendant à l'extérieur du réservoir ; et un filament s'étendant à l'intérieur du réservoir, le filament étant en communication fluidique avec une partie de la plume à l'intérieur du réservoir, de telle sorte que la solution d'encre se déplace le long du filament et à travers la plume, par action capillaire, la plume et le filament étant formés de telle sorte que pas plus de 50 pour cent du pigment présent dans la plume et le filament s'écoulent dans le réservoir à l'extérieur de la plume et du filament lorsque l'instrument d'écriture est rangé avec la plume remontée pendant une période d'un jour.
