14 A writing instrument in which plural cartridges are fitted and coupled in series with each other in their longitudinal direction so that the cartridges are removable from each other. Each of the cartridges comprises a tubular body having a tubular projection at one end of the tubular body and having an optionally shaped cross section, and a core unit inserted in the tubular projection so that the core unit is held in it. The tubular body has an insertion hole into which the tubular projection of the adjacent cartridge, which is coupled to the tubular body, is fitted in the longitudinal direction of each cartridge so that the tubular projection is held in the insertion hole removably from it. The former tubular projection has an insertion hole in which the core unit of the adjacent cartridge is housed. The circumferential outside of the tubular body has at least one engagement projection and at least one engagement groove, each of which can be engaged with the engagement groove or engagement projection of the tubular body of another cartridge so as to couple the cartridges in parallel with each other in their transverse direction removably from each other.
Instrument pour écrire dans lequel plusieurs cartouches sont insérées et couplées en série l'une avec l'autre dans leur direction longitudinale de façon à pouvoir détacher les cartouches l'une de l'autre. Chacune des cartouches comprend un corps tubulaire possédant une protubérance tubulaire à une extrémité et ayant une coupe de forme optionnelle, et un noyau inséré et retenu dans la protubérance tubulaire. Le corps tubulaire comprend un trou d'insertion dans lequel s'insère la protubérance tubulaire de la cartouche contiguë, qui est couplée au corps tubulaire, dans la direction longitudinale de chaque cartouche de sorte que la protubérance tubulaire soit retenue dans le trou d'insertion de façon non permanente. La protubérance tubulaire antérieure possède un trou d'insertion dans lequel est logé le noyau de la cartouche contiguë. L'extérieur circonférentiel du corps tubulaire comprend au moins une protubérance d'engagement et au moins une rainure d'engagement, chacune pouvant s'engager avec la rainure ou la protubérance d'engagement du corps tubulaire d'une autre cartouche afin de coupler de façon non permanente les cartouches en parallèle l'une par rapport à l'autre dans leur direction transversale.
