Abstract
A combined container and child-resistant closure system includes a double-shell cap with a first skirt and a second skirt disposed within the first skirt. A pair of opposing protrusions extend from an interior surface of the first skirt. A pair of opposing finger pads are provided on an exterior surface of the first skirt. An interior surface of the second skirt is threaded. The container includes a threaded neck and a collar at the base of the neck. An outer edge of the collar forms an ellipse with major and minor axes. A pair of opposing notches are provided at apses of the major axis. When the cap is tightened onto the container, the protrusions mate with the notches to prevent removal of the cap unless the finger pads are compressed, deforming the first skirt such that the protrusions are released from the notches.
