  • Patent number: 4841752
    Abstract: A theft deterrent apparatus is set forth wherein a plurality of nozzles are positioned within an elongate deflecting shield such that they may be manually and selectively activated by a foot pedal or secondary switch positioned for manual manipulation such as on a cash register. The nozzles dispense a disabling fluid chemical upon activation of a control valve by the foot pedal and cash register positioned switch. Optionally an overhead bank of similar fluid dispensing nozzles may be oriented where counter level positioning of such nozzles is not desirable. Alternatively, the counter mounted and overhead mounted nozzles may be utilized in combination.
