<p>The object of the invention is a method for use in connection with closing a liquid packaging container, the said container comprising a cylindrical or truncated cone-like casing part (1) and end members (2, 3) connected to it, of which at least one (3) is formed of fibre-based, such as board-based material, for example, liquid packaging board, and comprises a skirt (15) folded in the direction of the casing part, by which skirt the end member is connected to the casing (1), in which method the container, which is finished at least with respect to its casing part (1) and the said one end member, is filled with a liquid (4) and the container is closed. According to the invention, the surface of one end member (3) which is on the outside of the container is moistened before the container is closed, thus reducing its rigidity to such an extent that the end member can be used in a bellows-like manner for controlling the pressure inside the container.</p> |
