Abstract
A guarantee band for a container closure is connected to an adjacent element of the closure by a breakable separating section having a part stronger than the remainder of the section. The guarantee band has at least two weakened regions spaced around its periphery, one of said weakened regions being weaker than the other or others and the said weaker region being located near to said stronger section part. On removing the closure from a suitable container for the first time, the guarantee band will break at the said weaker region, the breakable separating section will break except at the stronger section part and the remaining weaker region or regions will each provide an articulation causing the guarantee band to adopt a drooping configuration to give an enhanced indication of breakage of the guarantee band.
