Liquid container, liquid supplying apparatus, and recording apparatus

The ink water tank, comprising at least one part (11) and transformable ink inlet section (10); A push-pull enlarged of the deformation part of the function of the power of the negative pressure spring for producing container to need; Is a shafts can according to the container the negative pressure is increased, further introduces the air to the inner layers; the negative pressure maintaining to the combined of air introduction part (16); And a one-way valve (30) for preventing the receiving the ink airtight accepting space (cushion) to connect of the ink to the outer, and allows of the outer to the receiving chamber introduction gas. From, a no the ink is slidingly connected to the air introduction part is any for environment and a preserved environment, and can with nothing to respectively with a degree of liquid consumption maintains stable the negative pressure the ink water tank.
