Abstract
Embodiments of a tamper-evident closure are disclosed which prevent unauthorized access to a container and its contents, deterring adulteration or introduction of counterfeit product. In one embodiment the tamper-evident closure can be fitted to an associated container and closure, and includes a portion which is removed by fracture of the tamper-evident closure to gain access to the container closure. In another embodiment, an arrangement of wedge-like tongues permit fitment of the tamper-evident closure to associated container for temper-evidence. In another embodiment, the tamper-evident closure is joined by frangible bridges to the container closure to provide the desired tamper-evidence. In another embodiment, the tamper-evident closure is movable axially of the associated container closure to thereby provide evidence of removal.
