ABSTRACT:
The disclosure relates to a method of providing a liquid package (2) with an opening arrangement (1) and to the opening arrangement (1) proper. A hole (3) is punched out in the material (15) of a package (2) of the type which is produced from a material web (15) or a material sheet, the hole being covered by a thin strip (4). Thereafter, the package (2) is filled and formed into its final shape. A plastic device (6) is secured on the finished package (2) so that it surrounds the strip (4) without covering it. The plastic device (6) consists of a pouring element (7) with an angled front edge (10) and a sealing element (8) with a locking angle (13). A hole is provided in the pouring element (7) wherein the strip (4) is visible in its entirety.
Before distribution of the package (2) the sealing element (8) is moved over the pouring element (7) so that these enter into engagement with one another and the locking angle (13) is locked against the front edge (10) of the pouring element (7).
