Abstract
A closure for a container has a tamper indicating band with a band retainer in the form of an apertured flap or hoop which is hinged to the lower edge of the band. A series of windows open through the retainer, extending toward but not to its distal edge. As the retainer is turned inside out from its as-molded position to its use position, its distal and/or hinged edges deform to relieve compression and permit the retainer to be inverted by direct downward pushing force. As a result of the deformation, the retainer in its use position may, depending on the number and size of windows, have an advantageous polygonal peripheral shape rather than a circular shape.
