The opening arrangement comprises a material strip (3), which is joined to the packing container material by means of y V-shaped weld (4). The point of/the V serves as a point of application of force (5) on opening of the package, and the opening arrangement is placed so in relation to the direction of orientation of the material that the material wall, after breaking up at the point of application of force, splits open along two substantially parallel lines in the direction of pulling, so that an emptying opening (7) is formed.</p> |
