A tamper indicating band which can be fitted over the scuff band of a conventional screw cap. The band has a larger diameter upper ring with a retaining bead which snaps over the scuff band and a smaller diameter lower ring which has a bead which snaps over a container bead. Unthreading the cap from the originally packaged container fractures frangible webs joining the bead's upper and lower rings. Evidence of initial opening or tampering remains by retention of the lower ring around the container neck. |
