  • Patent number: 12049087
    Abstract: The liquid storage unit includes a rectangular parallelepiped case having an open upper surface and a liquid storage pack including a rectangular parallelepiped adapter. The liquid storage pack is detachably housed in the case, the case includes a convex portion that protrudes from the inner side surface along a first direction perpendicular to a bottom surface, the adapter includes a concave portion that is formed on the outer side surface along a first direction and open to the lower surface, and the concave portion can engage with the convex portion in a second direction perpendicular to the first direction and parallel to the inner side surface, and is formed asymmetrically with respect to a surface that passes through the center of the adapter in the first direction and is perpendicular to the first direction.

  • Publication number: 20220379621
    Abstract: The object is to provide a liquid container capable of supplying liquid to a liquid ejection apparatus with simple configuration. Liquid container 100 has liquid containing bag 120 and an introduction member. The introduction member includes the first and second liquid introduction members. The first introduction member has the first spacer unit and the first coupling unit integrally connected to the first spacer unit in which the first groove for letting liquid flow to a liquid lead-out unit is formed. The second introduction member has the second spacer unit and the second coupling unit integrally connected to the second spacer unit in which the second groove for letting liquid flow to the liquid lead-out unit is formed. The first and second liquid introduction members are adjoined so that the surface on which the first groove is formed and the surface on which the second groove is formed face each other.
