Shark deterrent gun

Abstract

A tube is constructed of a heavy duty flexible or rigid plastic or metal and designed for the sealed storage and on demand release of a liquid or dry fish, animal or reptile repellent. Said tube may be a specially fabricated device or a standard fire extinguisher or other common liquid, gas or particle dispenser which can be incorporated into a lifesaving device such as a life guard rescue flotation buoy. The tube's predator specific repellent, for example sodium lauryl sulfate which is a known shark repellent, may be discharged by the user in the event of an attack by the predator. The purpose is to expose the predator to an immediate high concentration of the appropriate repellent thereby diverting the predator from it's attack.

I claim:  
     
         1 . A fish, reptile, or animal repellent system comprising: 
 a) a hollow tube having a proximal and a distal end;    b) sealing means disposed at said distal end for containing repellant material;    c) a species specific repellant disposed in said hollow tube; and    d) actuation means disposed at said proximal end of said hollow tube for initiating ejection of said repellant.    
     
     
         2 . The repellant system as set forth in  claim 1 , wherein said sealing means comprises two outer boundaries, said boundaries comprising blow away material.  
     
     
         3 . The repellant system as set forth in  claim 1 , wherein said actuator means comprises a canister of pressurized gas.  
     
     
         4 . The repellant system as set forth in  claim 3 , further comprising a separator wad interposed between said repellant material and said actuator means.  
     
     
         5 . The repellant system as set forth in  claim 4 , wherein said actuation means further comprises means for initiating operation thereof.  
     
     
         6 . The repellant system as set forth in  claim 5 , wherein said initiation means comprises a trigger.  
     
     
         7 . The repellant system as set forth in  claim 4 , said separator wad comprising a spherical plug.  
     
     
         8 . The repellant system as set forth in  claim 4 , said separator wad comprising a cylindrical plug.  
     
     
         9 . The repellant system as set forth in  claim 5 , wherein said actuation means comprises an internal propulsion system comprising carbon dioxide cylinders.  
     
     
         10 . The repellant system of  claim 9 , wherein said internal propulsion system further comprises triggering means operatively connected to said carbon dioxide cylinders.  
     
     
         11 . The repellant system of  claim 10  wherein said triggering means further comprises a rope that leads from said carbon dioxide propulsion system through the proximal end of said hollow tube.  
     
     
         12 . The repellant system of  claim 10  wherein said triggering means further comprises a pull rod that leads from said carbon dioxide propulsion system through the proximal end of said hollow tube.  
     
     
         13 . The repellant system of  claim 10  wherein said internal propulsion system further comprises a handle secured to said hollow tube.  
     
     
         14 . A device for buoying a swimmer and repelling sharks, comprising: 
 a) flotation buoy;    b) a hollow tube having a proximal and a distal end;    c) sealing means disposed at said distal end for containing repellant material;    d) a species specific repellant disposed in said hollow tube; and    e) actuation means operatively connected to said hollow tube for initiating ejection of said repellant.    
     
     
         15 . The repellant system as set forth in  claim 1 , wherein said hollow tube comprises plastic material.  
     
     
         16 . The repellant system as set forth in  claim 1 , wherein said repellant comprises sodium lauryl sulfate.  
     
     
         17 . The repellant system as set forth in  claim 4 , said separator wad comprising a plug comprising fibrous material.  
     
     
         18 . The repellant system as set forth in  claim 4 , said separator wad comprising a plug comprising plastic material.  
     
     
         19 . The repellant system as set forth in  claim 1 , wherein said hollow tube comprises a standard fire extinguisher.  
     
     
         20 . A device for buoying a swimmer and repelling sharks, comprising: 
 a) flotation buoy; and    b) a standard fire extinguisher detachably connected to said flotation buoy and being filled with a predator specific repellent and propulsion gasses.
