Abstract: A tamper-indicating, child resistant closure for a threaded bottle includes an inner cap and an outer driver telescoped over the inner cap. The inner cap includes a top wall having spaced apart upstanding ribs. The outer driver includes a top wall having a pair of top wall segments hinged for pivotal movement to, and being spaced apart from each other by a spacing rib also forming part of the top wall of the driver. Each of the top wall segments initially is secured to contiguous sections of the outer driver by frangible, tamper-indicating tabs, and the top wall segments are moved from a generally horizontal position to a generally vertical position after the tamper-indicating tabs have been broken to form a driving section in the top wall of the driver. This driving section then is directed into the space between the upstanding ribs associated with the top wall of the inner cap by moving the inner cap and outer driver axially toward each other.
