ABSTRACT:
This relates to a tamper indicating cap which includes a conventional closure of the threaded type. The closure is provided with an injection molded member which includes an inner ring that overlies and is bonded to an end panel of the conventional closure and an outer ring which is telescoped over and extends beyond a skirt of the conventional closure. The inner ring is joined to the outer ring by a first set of breakable bridges and a second set of bridges in the form of diagonal links. When the outer ring is turned in a cap removing direction, the two rings move relative to one another sufficiently to cause rupture of the first set of ribs to indicate tampering. The diagonal links then transmit cap removal torque to the center ring and from the center ring to the shell of the conventional closure.
