ABSTRACT:
A closure for a container has a tamper indicating band with band retaining means in the form of a conical hoop. The hoop is hinged to the band by arcuate hinges which are spaced by narrower windows along the hinge line, the windows extending partway toward but not to the inner edge of the hoop. As the hoop is turned inside out from its as-molded position to its use position, the inner edge of the hoop deforms radially adjacent the windows and thereby relieves hoop strength. As a result of the deformtion, the hoop in its use position assumes an advantageous polygonal peripheral shape rather than a circular shape.
