ABSTRACT:
A closure assembly comprises two separable closure members which are pre-assembled in coaxially stacked relationship, with their top panels aligned in the same direction. The lower closure member of the stack assembly comprises locking elements which are engagable with cooperating locking elements on a container, thereby providing a child-resistant closure. The upper closure is a simple snap cap, plug cap, or other closure which is not child-resistant. The upper closure is removably attached to the lower child-resistant closure by an interference fit between resilient attachment members integrally formed as parts of the upper and lower closures. The assembly can be separated, for use of the upper closure only for sealing the container, thereby providing a choice between a child-resistant and non child-resistant closure.
