Abstract
A tamper indicating closure for application to a container neck. The closure includes a cap having a top and an internally threaded skirt. A tamper indicating band depends from the bottom of the cap skirt by circumferentially spaced frangible connections. The band has ratchet teeth which engage ratchet teeth on the container neck, and a permanent tether rib connects the band to the cap so that the band remains with the cap when the closure is unthreaded from the container neck.
