摘要 |
The present invention prevents liquid leakage regardless of the using conditions and the reserving atmosphere and stabilizes a negative pressure regardless of the degree of liquid consumption, by having a one-way valve in the liquid container that supplies liquid to an external device, maintaining the negative pressure formed in the liquid supplying passage positioned in the downstream of a position where liquid or gas is supplied by the one-way valve. The liquid container has a deformable, movable unit at least a part of which is made of a flexible material. A space other than the liquid supply unit forms a substantially sealed space in which liquid is retained. The container is capable of supplying the liquid to the outside. Such container has a one-way valve that passes liquid or gas from the liquid container to the outside or from the outside to the liquid container.
