Patent

CA 2025057

A child resistant closure comprising outer and inner nested closure members each of which has a base wall and a peripheral skirt with sets of lugs on the inner surface of the outer base wall and the outer surface of the inner base wall adapted to engage each other when the outer closure is rotated for application to a container, but slip or cam past each other on inclined surfaces when the outer closure is rotated for removal. At least one integral spring finger extends from one base wall toward the other base wall such that the outer closure member is held out of engagement with the inner closure member. To remove the closure, the outer closure member must be pressed downward, while simultaneously being rotated. The camming action of the lugs is then resisted by a frictional engagement of corners of the lugs on the outer closure with inclined surfaces on the lugs on the inner closure.
