Patent

CA 2309108

A writing device (10) generally including a uniformly cylindrical main body (12) partially filled with a writing medium such as ink (14). A writing tip (19) is inserted into a first end (16) of the main body (12) and a first sealing member (24) is inserted into the second end (20) thereof. The first sealing member (24) is located in the main body (12) near the second end (20). A pressurized gas such as nitrogen (26) is disposed in the body (12) between the ink (14) and the first sealing member (24). Alternatively, a gas forming means may be located in the main body (12) to continually produce a gas as the ink (14) is depleted to maintain pressure therein. A second sealing member (28) is inserted into the second end (20) of the main body (12) to provide a dual seal gas pressurized system.

L'invention concerne un dispositif (10) d'écriture comportant un corps (12) principal uniformément cylindrique partiellement rempli à l'aide d'un support d'écriture tel que de l'encre (14). Une pointe (19) d'écriture est insérée dans une première extrémité (16) du corps principal, et un premier élément (24) d'étanchéité est inséré dans la deuxième extrémité (20) de celui-ci. Le premier élément (24) d'étanchéité est situé dans le corps (12) principal à proximité de la deuxième extrémité (20). Un gaz pressurisé tel que de l'azote (26) est placé dans le corps (12) entre l'encre (14) et le premier élément (24) d'étanchéité. Dans un autre mode de réalisation, un moyen de formation de gaz peut être placé dans le corps (12) principal afin de produire en continu un gaz à mesure que l'encre (14) est consommée, de façon à maintenir une pression à l'intérieur de celui-ci. Un deuxième élément (28) d'étanchéité est inséré dans la deuxième extrémité (20) du corps principal pour former un système pressurisé de gaz à deux éléments d'étanchéité.
