Abstract: A tamper evidence closure is provided for rotatably engaging with a finish of a container to seal contents within the interior of the container. A multiplicity of thin connections attach a tamper evidence band to a circumference of the tamper evidence closure. A segmented cam extends around the circumference of the tamper evidence band. An angled lower surface of the cam facilitates passing the tamper evidence band over a tamper evidence ledge of the finish during assembly of the tamper evidence closure onto the container. An upper surface of the cam engages with the tamper evidence ledge to break the thin connections and retain the tamper evidence band positioned on the finish during loosening of the tamper evidence closure. Multiple overhang portions above the cam press against an upper portion of the tamper evidence ledge to ensure that the tamper evidence band remains engaged with the tamper evidence ledge.
