A closure cap comprises in a transition range ( 7 ) between the cap base ( 2 ) and the cap skirt ( 3 ) a bulge ( 6 ) for pressing a sealing disk ( 5 ) against a container opening. The bulge ( 6 ) comprises an undercut ( 8 ) and in sections ( 9 ) is provided with weakenings ( 10 ) which give the bulge ( 6 ) a radial flexibility.

1. A closure cap for a container, comprising a cap base, a cap skirt, with inner retaining elements which may be brought into engagement with outer retaining means of an opening of the container;a sealing disk which at least partly bears on the cap baseand a circumferential bulge arranged in a transition region between said cap base and said cap skirt, for pressing said sealing disk onto an upper outer edge of said opening of the container,wherein said sealing disk bears at a radially inner surface of said circumferential bulge,wherein the closure cap between said bulge and said skirt at least partly is provided with a circumferential undercut having a height, andwherein said bulge in at least one segment-like section has a weakening, and wherein said weakening does not extend the full height of said undercut. 2. A closure cap according to claim 1, wherein the undercut extends into a region which is distanced to an inner side of the cap base. 3. A closure cap according to claim 1, wherein the weakening of said bulge is formed by deepenings on an outer side of said bulge facing the cap skirt. 4. A closure cap according to claim 1, wherein said weakening of said bulge is formed by deepenings which extend from a lower said bulge axially towards said cap base. 5. A closure cap according to claim 4, wherein said deepenings extend over the whole thickness of the bulge. 6. A closure cap according to claim 1, wherein said undercut has a height and wherein the weakenings extend substantially as far as said height of said undercut. 7. A closure cap according to claim 1, wherein the sections having a weakening extend together over an angular range of 90° to 220°. 8. A closure cap according to claim 1, wherein said cap base on an inner side has at least one radial rib which radially extends at least over a sealing section of the cap base. 9. A closure cap according to claim 8, wherein the radial rib ends between neighboring weakenings of the bulge. 10. A closure cap according to claim 8, wherein the cap base has a circumferential rib, wherein the radial rib has a height which is larger than the height of the circumferential rib. 11. A closure cap according to claim 1, wherein the closure cap has three to fifteen sections with a weakening. 12. A closure cap according to claim 1, wherein the bulge is connected to the transition region. 13. A closure cap according to claim 1, wherein the bulge retains said sealing disk even after removal of said closure cap from the container. 14. A combination of a closure cap and a container having an opening, said closure cap comprising a cap base, a cap skirt, with inner retaining elements which may be brought into engagement with outer retaining means of the opening of the container;a sealing disk which at least partly bears on the cap base and a circumferential bulge arranged in a transition region between said cap base and said cap skirt, for pressing said sealing disk onto an outer upper edge of said opening of the container, an inner diameter of said bulge being larger than the diameter of the outer upper edge of said opening of the container,wherein the closure cap between said bulge and said skirt at least partly is provided with a circumferential undercut having height, and wherein said bulge in at least one segment-like section has a weakening, and wherein said weakening does not extend the full height of said undercut. 15. A combination according to claim 14, wherein the undercut extends into a region which is distanced to an inner side of the cap base. 16. A combination according to claim 14, wherein the weakening of said bulge is formed by deepenings on an outer side of said bulge facing the cap skirt. 17. A combination according to claim 14, wherein said weakening of said bulge is formed by deepenings which extend from a lower said bulge axially towards said cap base. 18. A combination according to claim 17, wherein said deepenings extend over the whole thickness of the bulge. 19. A combination according to claim 14, wherein said undercut has a height and wherein the weakenings extend substantially as far as said height of said undercut. 20. A combination according to claim 14, wherein the sections having a weakening extend together over an angular range of 90° to 220°. 21. A combination according to claim 14, wherein said cap base on an inner side has at least one radial rib which radially extends at least over a sealing section of the cap base. 22. A combination according to claim 21, wherein the radial rib ends between neighboring weakenings of the bulge. 23. A combination according to claim 21, wherein the cap base has a circumferential rib, wherein the radial rib has a height which is larger than the height of the circumferential rib. 24. A combination according to claim 14, wherein the closure cap has three to fifteen sections with a weakening. 25. A combination according to claim 14, wherein the bulge is connected to the transition region. 26. A combination according to claim 14, wherein said sealing disk bears at a radially inner surface of said circumferential bulge. 27. A combination according to claim 14, wherein the bulge retains said sealing disk even after removal of said closure cap from the container. 28. A closure cap for a container, comprising a cap base, a cap skirt, with inner retaining elements which may be brought into engagement with outer retaining means of an opening of the container;a sealing disk which at least partly bears on the cap baseand a circumferential bulge arranged in a transition region between said cap base and said cap skirt, for pressing said sealing disk onto an upper outer edge of said opening of the container,wherein said sealing disk bears at a radially inner surface of said circumferential bulge,wherein the closure cap between said bulge and said skirt at least partly is provided with a circumferential undercut, andwherein said bulge in at least one segment-like section has a weakening, wherein the radial rib ends between neighboring weakenings of the bulge. 29. A closure cap according to claim 28, wherein, wherein said weakening does not extend up to an upper end of said undercut.
