Zusammenfassung:	There is described an opening device (4, 4') for a package (1) of a packaging material (3) having a designated pour opening. The opening device (4, 4') comprises a base frame (9), a collar (10) integrally connected to and extending from the base frame (9) and a closing element (12) configured to cover and/or close the designated pour opening. The closing element (12) is detachably fixed to an initial contact portion (21) of the collar (10). The collar (10) comprises a sealing ring (24) having a first inner surface (26) facing the flow channel (11) and an outer surface (27) opposite to the first inner surface (26). The base frame (9) comprises a second inner surface (38) facing the outer surface (27). The base frame (9) comprises a first contact surface (29) configured to contact the packaging material (3) from a first face (7) and a second contact surface (30) configured to contact the packaging material (3) from a second face (8). The initial contact portion (21) is interposed between the first contact surface (29) and the pouring outlet (13). A thickness (d2) of an annular interface (16) interposed between the base frame (9) and the collar (10) is larger than a distance (d1) between the first contact surface (29) and the second contact surface (30).
