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.
Claims7
A sealing cap (1) for sealing a container opening (2), having a tear-off safety band (3) disposed on the lower edge of the cap, the said safety band being intended to engage under an annular bulge (4) on the container opening when the cap is put on, the said safety band having, to this end, a plurality of flexible tongues (6), which are oriented towards the central axis and which may be bent back when the cap is first put on and engage under the bulge (4) in the final position of the cap, characterised in that clips (7) are disposed below the tongues, at least partly on the side facing away from the cap base (11), the tongues (6) bearing against the clips when axial force is acting on the safety band in the opening direction.
