ABSTRACT:
Five embodiments of a tamper indicating molded plastic band that locks over a ledge on the closure and beneath a flange on the container. The cylindrical band is molded with continuous locking rings or interrupted tabs joined adjacent the top end bottom edge thereof and which extend inwardly and generally toward each other to form mechanical locking members. Depending upon the particular arrangement of the locking rings on the tamper indicating band, the band would be applied to the closure before or after threaded application to the container. The band may be used with a plastic or metal closure and with a plastic, metal or glass container having a threaded neck and outwardly extending radial flange therebelow beneath which the ring or tab will lock.
