ABSTRACT:
A child-resistant closure includes an inner cap threadable mountable to a container, and an outer cap attached to the inner cap and freely rotatable relative to the inner cap during a child-resistant mode, and interconnected with the inner cap for removal of the closure from the container when the closure is in a non-child-resistant mode. An intermediate member is rotatably mounted between the inner cap and the outer cap and movable between a first position prohibiting the inner and outer caps from being interconnected for removal from the container and a second position permitting the manipulation of the outer cap relative to the inner cap for interconnecting the inner and outer caps for removal of the closure from the container. The intermediate member includes a spring which axially biases the outer cap away from the inner cape and which additionally torsionally biases the outer cap to rotate the outer cap relative to the inner cap when the outer cap is released from interconnection with the inner cap to automatically return the closure to the child-resistant mode. While the closure is in the child-resistant mode, the outer cap is freely rotatable in a loosening direction of the closure. However, rotation of the outer cap in a tightening direction only serves to further tighten the inner cap on the container.
