ABSTRACT:
A cardboard/plastics film laminate package (1) is provided with an opening arrangement consisting of a channel (6) fixed to the top wall of the package over an opening area (4) bounded by a tearing line (3) part thickness perforations and an opening element (9). The opening element (9) is a strip having a pull-tab (10) at one end and a bent back penetrating portion (11) fixed at (14) to a part (14") of the opening area. On pulling the tab (10), the penetrating portion (11) wedges between the channel (6) and the opening area of the package and is forced to penetrate the opening area. On further pulling, the opening area of the package is torn away and removed through the channel (1) which then forms a pouring mouth.
