  • Patent number: 4862431
    Abstract: A cigarette case with built in electronic timing device is provided that aids in the withdrawal from cigarette smoking. When the user loads cigarettes into the case he sets a timing interval. After this interval the case emits a pleasing beeping sound signalling him that it is permissible to open the case cover and remove and smoke another cigarette. If he attempts to open the cover prematurely, a loud irritating alarm is set off. The elapsed time is displayed at all times. In an alternative embodiment, the cigarette case will not open until the preset time has elapsed.
