Abstract
A locking cap and container is provided for a container having an opening surrounded by a neck with container threads thereon that are sized and located to threadingly engage cap threads formed on a skirt of the cap. A shaped distal end is formed on a distal end of the container threads and a barb is formed on the distal end of the cap threads. A resilient locking tab extends from the container, and is located below the shaped distal end and spaced apart from the shaped distal end a distance sufficient to allow passage of the barb beyond the shaped distal end but sufficiently close to resiliently urge the barb into overlapping rotational alignment with the shaped end. The shaped end is configured to lockingly engage the barb when the tab holds them in alignment. Pushing down on the cap pushes the thread against the locking tab and allows disengagement of the barb from the shaped distal end and movement of the barb past the shaped distal end to unlock the cap.
