ABSTRACT:
A fluid dispensing device for use as anti-burglar device is disclosed which discharges a fluid, containing a chemical such as tear gas, into an area to be protected when an intruder causes the device to be actuated. The anti-burglar device employs an electrothermal actuator strip for causing fluid discharge when an electric current flows through it. In addition, the fluid dispensing device may also be used as a metered spray atomizing device by the addition of a timing device for periodically actuating the valve of the pressurized container for emitting sprays of atomized fluid into the atmosphere for the spray application of insecticides, disinfectants, deodorants, room air fresheners and the like.
