Abstract
A safety closure and container assembly including a container, cap and combined spring and sealing member. Retention nibs are formed on the inner surface of the skirt of the cap, and a spring and sealing member has a radially projecting flange that engages the retention nibs to prevent separation of the spring and sealing member from the cap. Cap and container locking elements are formed respectively on the inner surface of the skirt of the cap and the outer surface of the mouth of the container. The cap and container locking elements are engageable with and disengageable from each other by combined axial and rotary motion of the cap relative to the container. The spring and sealing member biases the cap and container locking elements toward locked engagement with each other when the cap is applied to the container. The cap and container locking elements are formed such that the sealing portion of the spring and sealing member is forced into the mouth of the container into sealing engagement therewith as the cap is rotated relative to the container so that the operator does not have to apply direct axial force to the cap in order to seal the container.
