    摘要： An improved tamper-evident closure cap assembly for a container is disclosed. The closure cap assembly includes a breakaway skirt portion molded as a unitary part of the main body of the cap. The skirt incorporates a lower annular ring which engages a corresponding tamper bead on a container to tear the skirt portion away from the cap upon removal of the cap from the container. An annular band extends below the ring at the outer circumference of the skirt, forming an angled channel below the ring and inside the annular band. A plurality of spaced ribs span the channel from the ring to the band to strengthen the ring while allowing expansion of the skirt during capping operations.
