ABSTRACT A tamper indicating closure for a container having a threaded neck includes a cup-shaped cap with internal threads and a substantially smooth exterior wall, the tamper indicating device taking the form of a satellite band which surrounds the cap and extends over a substantial portion of the height of the cap. The band is attached to the cap by a frangible con- nection. The satellite band covers so much of the side wall of the cap that it prevents gripping of the cap. When the cap has been sealed on a container and an attempt is made to open it, finger pressure applied to the band to reach removal torque will fracture the frangible connection between the band and cap. Also attempts to pull the band off the cap will break the frangible connection. Once the band has been removed from the cap the closure may be opened and closed in the conventional manner. The cap and band may be molded in one piece with the intermediate frangible flange or it may be molded as a separate satellite band assembly with an annular flange which will slip over the cap and snap into place by engagement with lugs formed on the cap. The satellite band may be snapped onto the cap body before or after capping. If the cap is pre-assembled, then on-drive lugs can be provided on the top of the cap to provide means for the initial closing.
