ABSTRACT:
A closure for a container has a skirt with a frangibly attached tamper indicating band having a band retaining element in the form of a conical hoop. The hoop is hinged to the band by arcuate hinges which are spaced by ports along the hinge line, the ports extending part way toward but not to the distal edge of the hoop. The band is connected to the skirt along a circumferential score line. Another line of weakness, generally parallel to the axis of the closure, extends across the width of the band from the circumferential score line downwardly to the hinge line between the hoop and the tamper evidencing band, and the hoop is split or separated from the hinge line, inwardly to its distal edge. The hoop is under hoop stress in its upfolded configuration and that stress causes the band to break and spring open when the closure is removed from a container, thereby providing more visible evidence of such removal and facilitating resealing. The hoop may be connected to the closure skirt so that the band and the hoop will remain attached to the closure upon opening, rather than separating, thereby obviating a possible source of litter.
