Abstract
A child resistant closure wherein a ratchet-type cap is threadably mounted on the neck of a container having a ring member integral therewith. A resilient tab having a ratchet tooth thereon is integral with the ring and engageable with ratchet teeth on the cap. The ratchet tooth on the tab and cooperating ratchet teeth on the cap are hidden from view to render the closure more child resistant.
