Portable self-protective device

Claim 1

A portable self-protective device adapted to be worn on the wrist of a person to be protected in the form of a bracelet, comprising a compartment integral with said bracelet, said compartment containing a quantity of protective fluid material under pressure on said compartment, an outlet nozzle for dispensing said protective fluid material in the form of a directionally controlled stream or spray; means in said compartment for selectively controlling the flow of said protective fluid from said compartment to said nozzle, said means comprising an elongated valve body having an outlet port in communication with said nozzle at one end thereof and at least one inlet port intermediate the ends of the body providing communication between the interiors of said compartment and said valve body; a valve means movable to and from said outlet port to control the flow of said protective fluid through said outlet port, said valve means being mounted integrally on the end of a valve rod extending through the interior of said valve body and seating on the upstream side of said outlet port so that said protective fluid material under pressure acts to more firmly seat said valve means on said outlet port, said valve means having a conical surface which seats on and enters into said outlet port, said valve rod extending out of the compartment and having a threaded portion which mates with cooperating threads on the interior surface of said valve body, whereby rotation of said valve rod by a wearer of the bracelet causes linear movement of said valve means to and from said outlet port to control the flow of protective fluid material through said outlet port, and rotary motion with respect to said outlet port to provide a wiping action between the mating surfaces of said outlet port and said valve means, spring biasing means for biasing said valve means to a closed position to prevent the flow of protective fluid material through said outlet port, control means for rotating said valve rod against the bias of said spring biasing means whereby said control means determines whether protective fluid material is dispensed to protect said person.
