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. In this orientation, the upstanding top wall segments also can be gripped to provide leverage in rotating the driver and inner cap in a counter-clockwise direction to unscrew the closure from the threaded neck of a bottle.

Closure with outer driver having movable segments forming manual

A tamper-evident closure includes a cap having an interior, threaded peripheral skirt, a tamper-evident ring disposed below the lower edge of the skirt and a plurality of elongate bridge members interconnecting the tamper-evident ring to the cap. Each bridge member includes a lower end forming a lower juction with the ring an upper end thinner than the lower end forming an upper juction with a surface of a recess formed in the skirt. Each bridge member is designed to break at the upper end thereof when the closure is rotated in a direction to remove it from the container, and each bridge member is inclined upwardly at an acute angle to the ring from the lower to the upper junction, in the direction in which the cap is required to be rotated to remove it from the container. Each of the bridge members has a stepped configuration for providing a bridge surface closely spaced to and facing the surface of the recess at which the upper junction is formed for engaging this latter surface when the cap is being rotated to secure the closure to the container.
