Abstract:
A liquid storing container from which a liquid is supplied to an exterior and in which the liquid is stored, said liquid storing container comprising:a deformable movable member which forms part of said container and has a portion molded into a convex form; negative pressure generating means for applying force to said movable member, an applying direction of said force being a direction opposite to a direction in which said movable member is deformed as the liquid is supplied, to maintain an interior of the container at negative pressure with respect to atmosphere; a frame member which forms part of said container and which fixes said deformable movable member at a peripheral section thereof, said frame member having an opening to allow the liquid to be extracted to the exterior; a plate member provided on a portion of the convex form of said deformable movable member; and an air passage section including an air introduction port in which a liquid meniscus is formed corresponding to pressure relative to the atmosphere and a path having a predetermined length so that the interior of said container communicates with the atmosphere via said path and said air introduction port; wherein said deformable movable member includes a deformable area between said frame member and said plate member, and said deformable area deforms according to extraction of the liquid from said container.
