An insert ( ) for a closure provides, in a single component, a gasket function between the end panel ( ) of the closure and the end sealing surface ( ) of a container neck finish ( ), a thread forming feature ( ) and a tamper evident band ( ). The sealing portion (gasket ( ) and thread forming feature ( )) of the insert is formed from soft pliant material so as to provide excellent sealing. The tamper evident band ( ) is made from much stiffer material than that of the sealing portion, thereby providing rigidity to the entire component. During assembly the integral tamper evident band ( ) thus maintains the insert in a circular and non-twisted shape, ensuring ease of handling of the insert.
