A child resistant cap for a bottle includes a cover portion with a periphery having a wall with an internal surface surrounds the neck when the cap is positioned on the bottle. The bottle includes a neck, an opening and a rib with a gap. A finger and a locking lug extend from the internal surface. The finger has a length less than a length of the gap. The locking lug has a length greater than the length of the gap. The locking lug and the finger engage the rib and permit a rotation between a first position, where the finger and gap are aligned and a series of second positions, where the finger and gap are not aligned. A tab extends from the cover portion for applying a force to the cover when the cap is in the first position to remove the cap from the bottle.
