Abstract
A safety overcap for a container, for example, an aerosol container. The child-resistant overcap includes a generally circular top wall and a generally cylindrical outer skirt depending downwardly from the top wall. The wall of the outer skirt is provided with a pair of opposed, longitudinally extending slots. An inner skirt depends downwardly from the top wall within the outer skirt and has two opposed portions positioned adjacent the pair of openings in the outer skirt. The inner skirt is provided with opposed, inwardly projecting beads on the lower portion thereof which enagage an annular groove provided at the top of the container to attach the cap to the container. By gripping the exposed portions of the inner skirt through the slots with the forefinger and thumb and applying pressure thereto, the inner skirt is distorted and releases the overcap from the container.
