ABSTRACT:
A tamper-evident closure adapted for assembly with a container includes a band which, upon first opening, completely separates from a cap portion and which, upon reclosing the container with the cap, is dislodged from engagement with the container to insure that the band falls freely around a neck portion of the container to provide a substantial space between the cap and the band and thereby provide readily discernible evidence that the container has been previously opened.
