Abstract
The tamper indicating closure disclosed herein is designed for use with containers having a threaded neck section and an annular bead or flange located below the threaded neck section. The tamper indicating closure includes a cap with a top wall and a downwardly extending annular side wall. The cap includes a thread on the inner surface of the side wall for locating the closure on the threaded section of the container neck, and a tamper indicating member is connected to the lower section of the side wall. The tamper indicating member includes an annular band with a plurality of upwardly extending locking tabs. A plurality of flexible hinges are used to interconnect the locking tabs and the annular band. The locking tabs are configured to react against the annular head or flange of the container neck to prevent the removal of the annular band from the container when the closure is in a closed position.
