Abstract
Abstract A chemical irritant spraying anti-burglary device in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder opens a window or opens a door or enters an unauthorized area with which the device is associated. The anti-burglary device employs a spring biased firing member for discharging a chemical irritant from a pressurized container. An improved means for releasibly retaining the firing member in a cocked position and for triggering the same to release the chemical irritant is described.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
172 words
A chemical dispensing anti-burglar device for use with a pressurized container including a projecting dispensing cap actuated to emit fluid discharge therethrough upon depression, the device assembly comprising: a body member; a means for supporting said pressurized container in said body member; an aperture in said body member in communication with said cap; a spring biased firing member supported in said body member arranged to actuate said dispensing cap thereby discharging said pressurized container through said cap and aperture when said firing member is released; means for releasably retaining said firing member in a cocked position displaced from said pressurized cap; said retaining means including a trigger element; said trigger element being mounted for rotatable movement within said body member between an actuation position and a release position; said trigger element in said actuation position in shouldered engagement with a surface of said firing member to retain said firing member in said cocked position; and said trigger in said release position allowing said firing member to depress said cap to cause discharge.
