Abstract
A combined childproof and tamperproof bottle closure is disclosed including a cap hinged to the container having a flap with improved childproof locking means adapted to engage cooperating locking means on the container. A tamperproof indicia is associated with the flap locking means, and is formed to break with the initial disengagement of the flap locking means from the container locking means to provide a warning of tampering with the container.
