Abstract
A method for refilling liquid using a refilling container is to refill liquid to a liquid reserving container, which is provided with a first chamber that houses a negative pressure generating member, at the same time, having an aperture conductively connected to the outside, and with a second chamber conductively connected with the first chamber through a communicating unit for forming essentially a closed space with the exception of the communicating unit. This method comprises the step of forming an essentially closed space from the atmospheric air by means of the second chamber and the refilling container with the exception of the communicating unit in a state where the liquid surface of the refilling container is positioned higher than the liquid surface of the second chamber, and the step of arranging the second chamber to be conductively connected with the refilling container by use of a first path that enables gas in the second chamber to communicate with gas in the refilling container, and a second path, which is different from the first path, arranged for shifting liquid in the refilling container into the second chamber. With the method thus arranged, liquid in the liqui…
