Abstract
A child resistant closure is used with an associated container. The closures includes a closure cap having a circular top wall portion and a depending annular skirt portion. The skirt portion has an edge region spaced from the top wall portion. The cap includes at least one pivotal release tab extending from the skirt portion and connected thereto by a connector. The connector extends between the tab and the skirt portion at about the edge region. The tab further includes a ratchet extending therefrom to engage the container. The closure is removed from the container by urging the release tab inwardly of the closure to disengage the ratchet from the container. The closure can include a tear away tamper-evident band overlying the release tab to provide visibly discernible evidence that the closure has been removed from the container.
