ABSTRACT:
A tamper-proof closure arrangement for a container includes in one embodiment a seal applied to seal receiving surfaces of the container and closure cap such that the seal is applied internally of the closure cap without removing the closure cap and is irreversibly damaged by any attempt to remove the closure cap, the seal being visible through the closure cap to provide a visual indication of tampering. In an alternative embodiment, the seal is fixed internally of a disposable cap which is mounted on an associated container to overlie a reusable closure cap. The seal is visually observable through the disposable cap and is formed in contacting relation against a three-dimensional surface on the reusable cap such that any attempt at removing the disposable cap irreversibly damages or deforms the seal to provide a visual indication of tampering.
