A pull-tab lid is proposed for a standard drinks can. A first pull-off region (5; 5a, 5b, 5c; 14) appears liable to open when a grip lug (6) is pulled. A second pull-off region (8, 9, 10; 13, 9) is provided next to or outside the first; the lid, or a segment (10) thereof, opens unexpectedly in the second region, instead of (as expected) opening in the first region (5, 14). This makes it easy to surprise the user when opening a can of this type without adversely affecting the simple and reliable opening of the can.
