Wearable personal protection spray canister with trigger and safety mechanism

Abstract

A fluid dispenser apparatus includes a sealed fluid reservoir container storing a volume of a fluid under a pressure higher than at least 140 psi, a nozzle juxtaposed with the sealed fluid reservoir container, and a trigger mechanically coupled with the nozzle. The nozzle has a fluid inlet that is configured to fluidly couple with the volume of the sealed fluid reservoir container and a fluid outlet configured to emit a stream of the fluid. When activated the fluid inlet of the nozzle is caused to permanently unseal the sealed fluid reservoir container and relate substantially all the fluid under pressure in the volume through the fluid outlet as the stream in a direction determined by a user.

What is claimed is: 
     
         1 . A wristband-mounted wearable personal protection spray unit, comprising:
 (a) a wristband;   (b) a slide cartridge carried on the wristband;   (c) a vessel, containing personal protection spray, that fits inside the slide cartridge; and   (d) a mechanism, integrated with the wristband, for activating the vessel to release the personal protection spray contained therein.   
     
     
         2 . The wristband-mounted wearable personal protection spray unit of  claim 1 , wherein the mechanism includes a vessel tab and a cartridge tab that are activated by squeezing them together. 
     
     
         3 . The wristband-mounted wearable personal protection spray unit of  claim 1 , wherein the personal protection spray includes capsaicin. 
     
     
         4 . The wristband-mounted wearable personal protection spray unit of  claim 1 , wherein the personal protection spray includes phenacyl chloride. 
     
     
         5 . The wristband-mounted wearable personal protection spray unit of  claim 1 , wherein the personal protection spray is an aerosol self-defense spray. 
     
     
         6 . A fluid dispenser apparatus comprising:
 a sealed fluid reservoir container storing a volume of a fluid under a pressure higher than at least 140 psi;   a nozzle juxtaposed with the sealed fluid reservoir container, and having a fluid inlet that is configured to fluidly couple with the volume of the sealed fluid reservoir container and a fluid outlet configured to emit a stream of the fluid; and   a trigger mechanically coupled with the nozzle and configured, upon activation, to cause the fluid inlet of the nozzle to permanently unseal the sealed fluid reservoir container and relate substantially all the fluid under pressure in the volume through the fluid outlet as the stream in a direction determined by a user.   
     
     
         7 . The apparatus of  claim 6 , wherein the fluid reservoir container comprises a non-cylindrical geometry defining the volume. 
     
     
         8 . The apparatus of  claim 6 , wherein the fluid reservoir container comprises a substantially ovoid geometry defining the volume. 
     
     
         9 . The apparatus of  claim 8 , wherein the ovoid comprises a maximum dimension of no more than 50 mm. 
     
     
         10 . The apparatus of  claim 6 , wherein the fluid reservoir container comprises at least one depression sized and dimensioned to receive at least a portion of the nozzle. 
     
     
         11 . The apparatus of  claim 6 , wherein the volume is no more than about 15 ml. 
     
     
         12 . The apparatus of  claim 11 , wherein the volume is no more than about 4 ml. 
     
     
         13 . The apparatus of  claim 12 , wherein the volume is no more than about 4 ml. 
     
     
         14 . The apparatus of  claim 6 , further comprising a housing that contains at least the reservoir. 
     
     
         15 . The apparatus of  claim 14 , wherein the housing comprises a cover and a detachable base, where the cover releasably couples to the detachable base and permits replacing of the fluid reservoir container. 
     
     
         16 . The apparatus of  claim 14 , further comprising a clip holder coupled to the housing and a clip configured to couple with the clip holder. 
     
     
         17 . The apparatus of  claim 14 , further comprising an appendage strap configured to couple to the housing and sized and dimensioned to strap the housing to a human wrist. 
     
     
         18 . The apparatus of  claim 1 , wherein the fluid inlet comprises a needle portion configured to pierce the sealed fluid upon activation by the trigger. 
     
     
         19 . The apparatus of  claim 18 , wherein the fluid inlet is shaped to depress an internal valve releasing the pressurized contents of reservoir upon activation by the trigger. 
     
     
         20 . The apparatus of  claim 1 , wherein the irritant comprises a pepper derived irritant and a marking component.
