摘要

The present invention relates to a liquid container (100) having a negative pressure generating member containing chamber (134) containing therein at least two negative pressure generating members (132A, 132B), and both negative pressure generating members (132A, 132B) are urged against each other so that said urged portions form an interface (132C) which intersects with said partition wall (138), wherein a capillary force in the interface (132C) of said urged portions is equal or larger than the sum of the water head difference (h) between the liquid in the first and second negative pressure generating members and a capillary force of the second negative pressure generating member (132A).
