Abstract

A closure cap (1) comprising thermoplastic material has a guarantee strip (4) which is joined to the closure cap by way of desired-rupture web portions (5). Besides the desired-rupture web portions (5) the guarantee strip is also joined to the closure cap by way of a reinforced region which comprises two substantially vertically extending holding web portions (8). The guarantee strip (4) is interrupted by a slot (9) between the two holding web portions so that the guarantee strip forms an open loop and can in any event be readily removed from the neck (3) of the container.
