ABSTRACT:
A tamper-indicating device is provided for use with two relatively movable parts. In a preferred embodiment, the device is incorporated in a tamper-evident closure having a closure body and a cover for engaging the body in a closed position. A resilient member is carried within the cover, and a releasable retaining structure is provided for holding the resilient member in a maximally deformed first orientation within the cover when the cover is in the closed position. When the cover is opened, the resilient member is released so as to assume a less deformed orientation. The cover includes an inspection means for permitting visual inspection of the released resilient member to indicate that the cover has been moved away from the initially closed position.
