<p>This invention relates to a method for closing a liquid packaging container to reduce the oxygen content of the gas remaining inside the container, when the container comprises a casing (1) - which includes body (2), cover (3) and bottom (4) parts - and a fill opening (5) on the casing (1), the said method including the filling of the container when the casing (1) is ready with liquid (6) through the fill opening (5), and the closing of the container by attaching a closing flap (7) on top of the fill opening. According to the invention the closing flap (7) is placed on top of the fill opening (5) either before or after the container is filled and it is first attached only partly to the casing part (3) surrounding the fill opening (5); after the container is filled, a feed nozzle (8) is led into the container through a gap between the edge of the fill opening and the closing flap; through the feed nozzle, at least essentially oxygen-free gas is fed into the container; the feed nozzle (8) is removed from the container through the gap between the closing flap (7) and the edge of the fill opening (5) and the closing flap (7) is pressed against the casing part (3) surrounding the fill opening and attached to this part to close the container.</p> |
