ABSTRACT:
A convertible child-resistant closure comprises an outer closure and an inner resilient liner. When applied to a cooperating container in the child-resistant mode, the resilient liner is distorted between the container rim and abutments formed on the outer closure panel, thereby providing an upward locking bias to the closure. The upper surface of the liner includes depressions adapted to receive the abutments only when the liner and the outer closure are in a particular relative angular orientation. To convert the assembly to a closure which is not child-resistant, the liner is removed and reoriented so that the abutments are received within the depressions, thereby preventing the abutments from distorting the liner to provide the locking bias.
