Abstract
This disclosure relates to a tamper-indicating band which is utilized in conjunction with a closure for normally preventing the distortion of the closure as would be required to effect the removal of the closure. A tamper-indicating ring includes a continuous band which must be ruptured in order to remove the tamper-indicating ring. When the processing of the container assembly requires the introduction of heat, the tamper-indicating ring is heated and the band expands and then shrinks. Difficulties encountered with this first expansion and later shrinkage have been solved by forming the band in a plurality of sections connected together by expansion segments.
