A tamper evident closure for use on a container has a closure overcap shaped to fit onto a dispensing cap, the dispensing cap being shaped to fit onto the container. The closure overcap is connected to a tamper evident band by fragmentable webs, and the tamper evident band attaches to the dispensing cap, as described below, so that removal of the closure overcap requires the fragmentable webs to be broken, thus providing evidence of the access. The fragmentable webs are strong enough so that it is only easy to break the fragmentable webs one at a time. The dispensing cap includes an upwardly extending cam that functions to break the fragmentable webs one at a time when the closure overcap is twisted with respect to the dispensing cap.

[ What is claimed is:] [1.]1. A tamper evident closure for a container, the tamper evident closure comprising:a closure overcap having a top wall portion and a generally cylindrical skirt portion depending therefrom, the skirt portion terminating in an overcap terminal edge, the overcap terminal edge being planar except for an indented portion extending upwardly towards the top wall portion;a tamper evident band connected to the skirt portion by a plurality of fragmentable webs, the tamper evident band having an inwardly directed flange;a dispensing cap having a dispensing orifice surrounded by an annular cap shoulder upper surface, the annular cap shoulder upper surface conforming to the overcap terminal edge, and including an upwardly extending cam conforming to the indented portion when aligned therewith;an annular snap groove formed in the dispensing cap beneath the annular cap shoulder upper surface, the annular snap groove being disposed in a plane that is parallel with a plane passing through the annular cap shoulder upper surface, the annular snap groove receiving and frictionally engaging the inwardly directed flange of the tamper evident band when the overcap terminal edge seats against the annular cap shoulder upper surface; andwhereby twisting the closure overcap when it is attached to the dispensing cap causes the upwardly extending cam to push the overcap terminal edge away from the annular cap shoulder upper surface, thereby breaking the plurality of fragmentable webs one at a time.
