PCT No. PCT/CH96/00211 Sec. 371 Date Feb. 23, 1998 Sec. 102(e) Date Feb. 23, 1998 PCT Filed Jun. 4, 1996 PCT Pub. No. WO97/00210 PCT Pub. Date Jan. 3, 1997A closure cap for closure of containers possesses a closure base (2), a wall (3), and a pull-off ring (7). The pull-of ring is connected to the wall (3) at connecting points (8). In order to open the closure cap, a force is exerted onto the pull-off ring (7), by which means two vertical frangible lines (9) lying adjacent to the connecting points (8) will be destroyed. As a result, an area of the wall (3) can be bent outwards and opening of the closure cap will be facilitated.
