<p>A tamper evident closure (18) for a container (10) having a closed endcap (20) with an overcap (22) to coaxially rotate thereabout. The overcap (22) is provided with an integrally formed knife blade (64) which is constructed and arranged to engage a weakened annular band (24) in the container wall (14) near the endcap (20). The knife blade (64) is located within a well (26) which is an integral part of the overcap (22). As the overcap (22) is rotated, the knife blade (64) engages and severs the annular band (24), and separates the closure (18) including the endcap (20) and the rotatable cap (22) from the body of the container (10). An annular channel (48) may also be provided to support the overcap (22) during rotation and thus maintain the alignment of the blade (64) with the weakened annular band (24).</p> |
