  • the lower surface 142 closer to the rotation center O than the lower surface 42 moves less than the lower surface 42 when the ink cartridge 30 is rotated from the first posture to the second posture, so the lower surface 142 moves in the removal direction 52. Even if it extends, it is difficult to interfere with the lower surface of the guide groove 109.

Abstract

La présente invention concerne un moyen qui permet à un utilisateur de faire tourner facilement une cartouche de liquide pour libérer la cartouche de liquide d'un état positionné dans un dispositif de consommation de liquide. Une cartouche d'encre 30 peut, tout en étant montée dans une section de montage 110 de cartouche, tourner entre une première position dans laquelle une surface de verrouillage 151 est en contact avec une section de verrouillage 145 tout en étant tournée dans la direction de retrait 52 et une seconde position dans laquelle la surface de verrouillage 151 se situe à une distance de la section de verrouillage 145 dans la direction vers le bas 53, la rotation de la cartouche d'encre 30 étant effectuée autour du centre d'une ouverture d'alimentation en encre 71 servant de centre O de rotation, l'ouverture d'alimentation en encre 71 ayant une aiguille à encre 102 introduite dans celle-ci. Dans la première position, la cartouche d'encre 30 ne peut pas se déplacer dans la direction de retrait 52 par rapport à la section de montage 110 de cartouche. Dans la première position, une surface inférieure 142 et une surface inférieure 42 se situent à une distance du centre O de rotation dans la direction de retrait 52.
