ABSTRACT:
A tamper-proof closure arrangement for a container includes a shrinkable 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. In a preferred embodiment, the seal surfaces comprise three-dimensional surfaces formed on the container neck and on the closure cap internally of a skirt portion of the cap. The seal is visible through the closure cap such that any attempt at removing the cap irreversibly damages or deforms the seal to provide a visual indication of tampering.
