ABSTRACT:
A tamper evident closure apparatus is described in which a closure sensing switch is positioned inside of a container for nonprescription drugs and the like for producing a lid removal signal upon the removal of the lid from the container. A sound signal generator responds to the lid removal signal and generates an auditory sound of safety signal informing the person opening the container that the lid has not been previously removed. A safety circuit also responds to the removal of the lid and inhibits the sound signal generator from responding to a second or subsequent lid removal signal so that the replacement and subsequent removal of the lid will not trigger the generation of a second sound of safety signal.
