Abstract
A tamper-evident container closure and container assembly with tamper-evident ring which breaks away from the cap as the cap is unscrewed. The cap includes a pawled ring with a plurality of breakable connectors and connection of the pawl tips to the cap providing coupling of the ring to the cap. During assembly, the pawls ride over ratchet teeth on the container breaking the pawl connections to the container. When the cap is removed, the pawls interlock with the ratchet teeth breaking the breakable connectors. The ratchet teeth may be arranged in two sets of teeth offset from one another to provide reduced back-off and reduced back-off torque.
