Abstract:
A closure (1) having a shell (10) and a polymer insert (20). The polymer material of the insert (20) is selected to be sufficiently soft to provide an adequate sealing surface (21) and yet sufficiently stiff to define legs (22), which clip behind the internal curl (11) of the closure shell (10).
