Abstract
The present invention provides a liquid injection apparatus for injecting liquid into a container, comprising an injection chamber, a container for a liquid to be injected and entirely sealed except an injection port is placed in the injection chamber with the injection port directed to the bottom, an injection cell comprising at least one unit injection cell to accommodate the liquid to be injected is installed in the injection chamber, there is provided pressure regulating means to reduce the pressure in the injection chamber and to regulate pressure in the injection chamber to the atmospheric pressure or to a level higher than the atmospheric pressure, the pressure in the injection chamber is reduced to a level lower than the atmospheric pressure by the pressure regulating means at least once, and then, by maintaining the atmospheric pressure or the pressure higher than the atmospheric pressure, the liquid is injected through the injection port.
