<p>This disclosure relates to a safety closure associated with a container having a threaded finish, the closure including a closure body having an end panel and a peripheral skirt with inwardly opening diametrically opposed recesses having surfaces for camming a gripping element against the container finish automatically upon rotation of the closure in an unthreading direction. The gripping element is an inverted generally U-shaped member having ends exposed through apertures in the peripheral skirt which can be gripped to move the member toward the widemost portion of the recesses thereby releasing the gripping element to permit the unthreading of the closure from its associated container finish.</p> |
