<p>A captive closure cap is retained to the neck of a container by a retaining strip (5). A retaining ring (3) engages with a bead (4) around the opening of the container when the closure cap is set on the container. The cap wall (2) is firmly secured to said retaining ring (3) by the retaining strip (5). The retaining ring (3) forms at the same time a warranty seal for the closure cap. In the original state, the retaining strip (5) extends between the cap wall (2) and the retaining ring (3) around the circumference of the closure cap and is linked by breaking webs (14, 14a) both to the retaining ring and to the cap wall lower edge. In order to reduce the risk of said breaking webs (14, 14a) being destroyed while the closure cap is mounted and at the same time to ensure that the retaining ring (3) firmly retains a closure cap on the opening of the container, the retaining ring is provided with several latchets (8) that project radially inwards from its inner surface and that extend upwards against the cap bottom (1) when the closure cap is set on the container, engaging with the bead (4) around the container opening.</p> |
