ABSTRACT OF THE DISCLOSURE This relates to a composite closure which incorporates the conventional closure of the press-on, twist-off type including a metal shell having in the center of an end panel thereof a tamper indicating button. The composite closure includes an overcap which is frictionally interlocked with the shell and wherein the shell has been modified so that the curl at the lower edge of the skirt thereof is outturned as opposed to being inturned and the rougher coating for receiving the sealing compound increases the frictional connection between the overcap and the metal shell. In addition, the overcap is provided with a tamper indicating band which is interlocked with the container finish so as to prevent both axial upward movement and circumferential movement of the tamper indicating band relative to the container finish. This permits, with controlled tolerances, an interlocking relation between the composite closure and the container wherein when the composite closure is twisted to remove the same the tamper indicating band will be first released and thereafter the seal between the closure and the container is broken and the tamper indicating button will pop-up in a normal manner.
