Claim:
1. A liquid cartridge configured to be inserted into a liquid consuming apparatus in a first direction along a horizontal direction against an urging force directed in a second direction opposite the first direction, and thereby to be mounted to the liquid consuming apparatus, comprising: a liquid chamber configured to store liquid therein; a front face facing the first direction when the liquid cartridge is inserted into the liquid consuming apparatus; a liquid supply portion positioned at the front face and configured to allow insertion of a liquid supply tube of the liquid consuming apparatus thereinto; a seal member positioned at the liquid supply portion and having a liquid supply opening formed therethrough, wherein the seal member is configured to contact an outer surface of the liquid supply tube while being elastically deformed when the liquid supply tube is inserted through the liquid supply opening; an upper face facing an upward direction when the liquid cartridge is inserted into the liquid consuming apparatus; a lock surface positioned at the upper face and configured to contact a lock portion of the liquid consuming apparatus in the second direction; and a lower face facing a downward direction opposite the upward direction when the liquid cartridge is inserted into the liquid consuming apparatus, wherein the liquid cartridge is configured to pivot about a pivot center which is a center of the liquid supply opening, when the liquid cartridge is inserted into the liquid consuming apparatus and the liquid supply tube is inserted through the liquid supply opening, wherein the liquid cartridge is configured to pivot between a first attitude and a second attitude, wherein when the liquid cartridge is in the first attitude, the lock surface contacts the lock portion in the second direction and movement of the liquid cartridge relative to the liquid consuming apparatus in the second direction is restricted, and wherein when the liquid cartridge is in the second attitude, the lock surface is positioned further in the downward direction than the lock portion, wherein when the liquid cartridge is in the first attitude, the lower face comprises a first portion and a second portion which are positioned further in the second direction than the pivot center, and the second portion is positioned further in the second direction than the first portion and is positioned further in the upward direction than the first portion, wherein at least a part of the second portion of the lower face is positioned further in the first direction than the lock surface, and the part of the second portion of the lower face faces a lower portion of the liquid consuming apparatus when the liquid cartridge is inserted into the liquid consuming apparatus.
