Abstract
This disclosure relates to a child resistant closure for a container of the type including a neck finish adapted to have rotationally removed therefrom a closure. The closure includes a closure member which is applied to a container neck in a conventional manner and an overcap which is telescoped over the closure member and is normally freely rotatable relative thereto whereby removal of the closure member is normally prevented. The overcap is, however, radially shiftable relative to the closure member and there ae interlockable means carried by the overcap and the closure member which are engaged upon such radial shifting so as to interlock the overcap with the closure member and permit the transfer of a rotational force applied to the overcap to be directed to the closure member to effect the removal thereof.
