Abstract
The sealing cap (1) has a tear-off safety band (3) on its lower edge, the safety band having inwardly-projecting tongues (6) on its inner wall (5). A clip (7) is provided below each tongue. When a container opening is sealed for the first time, the tongues (6) are bent upwards and engage below a bulge on the container opening. The tongues are prevented from bending downwards by the clips (7), so that when the sealing is first removed, the safety band (3) is torn off.
