Abstract

L'invention concerne une cartouche de liquide qui est conçue pour être insérée dans un appareil de consommation de liquide dans une première direction le long d'une direction horizontale contre une force de poussée dirigée dans une seconde direction opposée à la première direction et, de ce fait, être montée sur l'appareil de consommation de liquide. La cartouche de liquide est conçue pour pivoter autour d'un centre de pivotement dans l'appareil de consommation de liquide. La cartouche de liquide comprend une face arrière, et la face arrière comprend une première partie et une seconde partie positionnée davantage dans une direction vers le haut que la première partie. La première partie comprend une partie positionnée davantage dans une direction vers le bas que le centre de pivotement, et la première partie est positionnée davantage dans la première direction que la seconde partie.
