Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
218 words
A personal protective repellent dispensing device comprising an exterior housing member of attractive appearance in the form of an article which normally is conveniently carried as an accessory by a person in a readily accessible manner and which disguises the nature of the device, container means for containing a fluid substance of foul and repulsive nature within the exterior housing member, said exterior housing member having at least one outlet opening to the exterior thereof communicating with said container means, selectively controllable dispensing means coacting with said container means for releasing a fluid substance contained therein through the outlet opening under the control of a person carrying the device, and positive acting safety lock means on said housing member for positively preventing inadvertent actuation of the selectively controllable dispensing means, said positive acting safety lock means including spring means under tension for positively locking the safety lock means in the safety lock position and requiring that the spring means be tensioned further in order to change the selectively controllable dispensing means from a safety locked position to a ready armed detent position where it can be selectively and readily operated by a person carrying the device in situations where it is desired to arm the device and condition it for operation by the selectively controllable dispensing means alone.
Claim 2
Dependent Claim

A personal protective repellent dispensing device comprising an exterior housing member of attractive appearance in the form of an article which normally is conveniently carried as an accessory by a person in a readily accessible manner and which disguises the nature of the device, container means for containing a fluid substance of foul and repulsive nature within the exterior housing member, said exterior housing member having at least one outlet opening to the exterior thereof communicating with said container means, selectively controllable dispensing means coacting with said container means for releasing a fluid substance contained therein through the outlet opening under the control of a person carrying the device, and positive acting safety lock means on said housing member for positively preventing inadvertent actuation of the selectively controllable dispensing means, said positive acting safety lock means including spring means under tension for positively locking the safety lock means in the safety lock position and requiring that the spring means be tensioned further in order to change the selectively controllable dispensing means from a safety locked position to a ready armed detent position where it can be selectively and readily operated by a person carrying the device in situations where it is desired to arm the device and condition it for operation by the selectively controllable dispensing means alone.
Claim 3
Dependent Claim
55 words
A personal protective repellent dispensing device according to claim 1 wherein the container means is filled with a fluid substance of foul and repulsive odor which also is colored so that upon release and contact with an intruder, the intruder will be marked both by a foul odor and a readily identified visually observable mark.
Claim 4
Dependent Claim
35 words
A personal protective repellent dispensing device according to claim 2 wherein the fluid substance is a synthetic liquid having the odor of a skunk and dyed with a brightly colored readily visually identified marking substance.
Claim 5
Dependent Claim
39 words
A personal protective repellent dispensing device according to claim 1 wherein the selectively controllable dispensing means can be returned to the safety locked position in the event the device is not operated while in the ready armed detent position.
Claim 6
Dependent Claim
53 words
A personal protective repellent dispensing device according to claim 4 wherein the selectively controllable dispensing means for ejecting the fluid under pressure comprises a spring actuated piston member movable within the container for pressurizing the fluid and ejecting it under pressure through the outlet opening upon operation of the selectively operable dispensing means.
Claim 7
Dependent Claim
60 words
A personal protective repellent dispensing device according to claim 4 wherein the fluid of foul and repulsive nature is retained in an ampule under pressure in mixture with an expansible gaseous substance in the container, and operation of the selectively controllable dispensing means releases the contents of the ampule through the outlet opening in the manner of an aerosol spray.
Claim 8
Dependent Claim
43 words
A personal protective repellent dispensing device according to claim 5 wherein the spring means under tension for positively locking the safety lock means in the safety locked position is comprised by the same spring as the spring for the spring actuated piston member.

A personal protective repellent dispensing device according to claim 7 wherein the spring actuated piston member has a guideway pin formed thereon riding in a guideway formed in the side of the container means, said guideway being in the form of an inverted horseshoe with one short leg and one long leg, the positive acting safety lock means being comprised by the short leg of the inverted horseshoe shaped guideway while the guideway pin is retained therein under tension by said spring means, and the ready armed detent position being formed by an indentation in the inverted horseshoe shaped guideway near the juncture of the short and long legs thereof with the guide pin disposed in said indentation under tension from said spring means.
Claim 10
Dependent Claim
44 words
A personal protective repellent dispensing device according to claim 8 further including means responsive to operation of the selectively controllable dispensing means for producing a loud noise simultaneously with the ejection of a fluid substance of foul and repulsive nature through the outlet opening.
Claim 11
Dependent Claim
62 words
A personal protective repellent dispensing device according to claim 8 wherein the fluid substance of foul and repulsive nature is retained in an ampule under pressure in a mixture with an expansible gaseous substance in the container and operation of the selectively controllable dispensing means releases the contents of the ampule through the outlet opening in the manner of an aerosol spray.
