ABSTRACT:
A tamper indicating closure having a threaded cap and a tamper indicating band connected to the cap by frangible webs and by a tether structure which permits threaded attachment of the closure to the container with the band positioned below an annular flange on the container so that unthreading of the cap permits deformation of the tether structure until all of the webs are fractured after which unthreading causes the tether structure to pull a localized area of the band over the annular flange to permit removal of the band and cap as a unit from the container.
