Liquid supplier, liquid supply system, and method of manufacturing liquid supplier

A liquid supplier that is configured to be attached to and detached from a case of a liquid ejection device including a case storage;

• the case that moves along a +Y direction in order to be inserted into the case storage;
• a liquid introduction member located at an end of the case storage on the +Y direction side;
• a device-side electric connector located at the end of the case storage on the +Y direction side;
• and a first positioning portion and a second positioning portion located at the end of the case storage on the +Y direction side, the liquid supplier comprising:
• (A) a containing portion that contains a liquid, the containing portion including an injection port for injecting the liquid into an inside of the containing portion;
• and
• (B) a connection member located at an end of the containing portion on the +Y direction side when the liquid supplier is in an attached state of being attached to the liquid ejection device, the connection member including
• a liquid outlet port that receives the liquid introduction member in the attached state,
• a container-side electric connector that, in the attached state, comes into electrical contact with the device-side electric connector while receiving at least a force having a component in a +Z direction from the device-side electric connector,
• a first receiving portion that receives the first positioning portion in the attached state, the first receiving portion is located on a −X direction from the liquid outlet member, and
• a second receiving portion that receives the second positioning portion in the attached state, the second receiving portion is located on a +X direction from the liquid outlet member, wherein
• a main body of the connection member, which is configured to be separated from the case, has a width in the Z direction being smaller than a width in the Y direction and a width in the X direction in an orientation where the liquid supplier is in the attached state,
• the connection member includes a cover member and a bottom member, wherein a majority of an insertion portion is provided in the bottom member, the insertion portion provided to engage an engagement receiving portion of the case, and
• a direction parallel to a gravity direction is defined as the Z direction, a direction of the Z direction that is the same as the gravity direction is defined as the +Z direction, a direction of the Z direction that is opposite to the gravity direction is defined as a −Z direction, a direction orthogonal to the Z direction is defined as the Y direction, one direction of the Y direction is defined as the +Y direction, the other direction of the Y direction is defined as a −Y direction, a direction orthogonal to the Z direction and the Y direction is defined as the X direction, one direction of the X direction is defined as the +X direction, and the other direction of the X direction is defined as the −X direction.
