<p>A tamper-indicating plastic closure for a container having an anular locking ring includes a closure part cap (10) and a pilfer band (20) connected to the closure part at a frangible connection (22). A plurality of circumferentially spaced substantially rigid tabs (26) extend generally inwardly from an inner surface of the pilfer band (20), and the length of at least one of the tabs (26a, 26b) is shorter than the length of the remaining ones of the tabs (26). The tabs (26) have lengths sufficient to engage the annular locking ring to provide tamper-indication when the closure part (10) is removed from the container, and the shorter tabs (26a, 26b) are not permanently deformed by the locking ring when the closure is applied to the container. The pilfer band preferably has at least one weakened region, and the shorter tabs (26a, 26b) are positioned adjacent the weakened region.</p> |
