TAMPER INDICATING DEVICE FOR CONTAINER CLOSURE ASSEMBLY ABSTRACT OF THE DISCLOSURE This disclosure relates to a tamper-indicating device (18) for a container closure (16) to normally pre- vent the distortion of the closure as required to remove the closure. The tamper-indicating ring (18) includes a continuous band (44) which must be ruptured in order to remove the tamper-indicating ring. When the processing of the container assembly (10) 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 (54) connected together by expansion segments (56).
