ABSTRACT:
A method for filling a container involves supplying a barrier layer to the inside of a container and irradiating the inside with a high energy ray to form a barrier layer on the inner surface of the container and simultaneously sterilizing the inside and discharging a residual barrier material precursor gas and a by-product gas from the container before or during the filling of liquid food into the container. The method allows the formation of a continuous barrier layer covering edges, gloves, clearances and gaps inside the container. Automatic and effective discharge of a residual barrier material precursor gas and a by-product gas from the container through the filling of liquid food is allowed. The method avoids the necessity of chemical disinfectants through sterilization of the inside of a container by irradiation with a high energy ray and thereafter filling a liquid food in an aseptic state.
