Abstract:
1. A liquid container comprising: a container body that is detachably attachable to a container attachment unit of a liquid consumption apparatus so as to supply a liquid retained in an ink retainer portion inside the container body to the liquid consumption apparatus; a first and a second positioning portions that are provided on a first outer wall surface of the container body with a certain distance provided therebetween so as to prevent movement of the container body in a direction along the first outer wall surface thereof when a first and a second positioning members fit therein, respectively; the first and the second positioning members being provided on a first opposing surface of the container attachment unit to which the first outer wall surface thereof is opposed in an attached state; a liquid feed outlet that is provided on the first outer wall surface of the container body in such a manner that a liquid supply unit, which is provided on the first opposing surface, is communicated with the ink retainer portion inside therethrough when the container body is detachably attached to the container attachment unit; an information memory unit provided on the container body; electric contacts that are provided on a second outer wall surface of the container body, which is orthogonal to the first outer wall surface thereof and in the proximity of the first positioning portion, the electric contacts causing the information memory unit provided on the container body to be connected to an information control circuit of the liquid consumption apparatus when the electric contacts are press-contacted with a connection terminal, which is provided on a second opposing surface of the container attachment unit that is opposed to the second outer wall surface in an attached state; and an engaging portion that is provided on the second outer wall surface or on a side of a third outer wall surface, said third outer wall surface being parallel to the first outer wall surface and said side being near the second outer wall surface when viewed from a central axis of the first positioning portion, the engaging portion preventing the detachment of the container body from the container attachment unit when an engaging member provided on the second opposing surface engages therewith, wherein the second outer wall surface only faces in substantially one direction.
