ABSTRACT OF THE DISCLOSURE A closure system for containers, particularly semi-rigid containers has inlet- and outlet opening which can be varied in size, and can be covered by an adhesive strip. A tongue is formed by an essentially U-shaped cut in the container wall and may be raised up for opening the filling opening of the container, and on the innermost side of the container wall, on the area beyond the hinge line of the tongue, a piece of foil is adhesively fixed or sealed on which - on opening the closure system by tearing further the tongue cut line at its ends to form a larger emptying opening - is suitable for guiding the tear along its edge and thus determines the course of the tear lines.
