Abstract

L'invention concerne une cartouche d'encre équipant une imprimante, dont l'équipement de sortie d'encre comprend une pièce d'étanchéité destinée à empêcher l'écoulement d'encre. Cette pièce d'étanchéité comprend une partie de support qui épouse parfaitement la sortie d'encre. On prévoit également une bague d'étanchéité qui s'élève depuis la partie de support ; une butée combinée à la bague ; une partie de connexion venant entre la partie annulaire de ladite butée et la bague d'étanchéité. Au repos, la pièce d'étanchéité assure une bonne étanchéité. Parallèlement, lors de la perforation de l'aiguille de l'imprimante, la partie de connexion se rompt et entraîne la séparation de la bague d'étanchéité et de la butée. Grâce à la présence de la bague d'étanchéité qui épouse parfaitement l'aiguille d'impression, l'invention assure une excellente étanchéité même lors du fonctionnement de l'imprimante.
