ABSTRACT:
A tamper-indicating dispensing closure includes a closure body, and an associated flip-top lid pivotally connected to the closure body for movement between a closed position and an open position. The flip-top lid includes a tamper-indicating flange frangibly connected thereto, with the closure body including a pocket-like retention cavity within which the tamper-indicating flange is received during initial closing movement of the flip-top lid. During initial opening movement of the lid, the tamper-indicating flange is broken away from the flip-top lid, and thereafter permanently retained within the retention cavity to provide a clear, visual indication that the flip-top lid of the closure has been opened.
