ABSTRACT:
A cap (10) for closing a medicinal container (5) comprises a signal driver for emitting an audible (40) and/or visible (35) signal, a control circuit for timing or calculating a predetermined fixed time interval and then commanding the signal driver to emit its signal; a power source (15) for providing power to the signal driver and the control circuit; and a switch (20) disposed suitably on the cap for sensing the opening and closing of the cap (10). When the switch (20) is first cycled, the control circuit commands the signal driver to emit a verification signal; when the switch (20) is second cycled, the control circuit again commands the signal driver to emit a verification signal; and thereafter, when the switch (20) is opened a third time, the control circuit will begin timing its predetermined fixed time interval. At the end of every interval, the control circuit commands the signal driver to emit its normal alert signal.
