Non-lethal shotgun round with foam liner

Abstract

A non-lethal round of ammunition including an interior non-lethal projectile within an outer casing and a cylindrical foam liner, such as a Styrofoam® liner, surrounding non-lethal projectile. The foam liner is advantageous in that it guides and contains the round and dissipates some of the projectile energy so as not to severely injure the targeted person.

1 . A non-lethal shotgun round, comprising: 
 a base;    an outer cylindrical casing inserted within the base;    a cylindrical foam liner inserted within the outer cylindrical casing;    a projectile inserted within the cylindrical foam liner;    a cap covering the outer cylindrical casing; and    a propellant.    
   
   
       2 . The apparatus of  claim 1  wherein the foam liner contains an elastomeric bag containing said projectile.  
   
   
       3 . The apparatus of  claim 2  wherein said projectile is a particulate load.  
   
   
       4 . The apparatus of  claim 3  wherein a dye is enclosed in the elastomeric bag.  
   
   
       5 . The apparatus of  claim 4  wherein the dye is separated from the particulate load by a membrane.  
   
   
       6 . A non-lethal shotgun round, comprising: 
 a first cylindrical casing;    an ignitable propellent charge rearwardly disposed with said first casing;    a wad disposed as a barrier within said first casing forwardly disposed over said propellent charge;    a second cylindrical casing disposed within said first cylindrical casing forwardly located from said wad; and    a load within said second cylindrical casing.    
   
   
       7 . The apparatus of  claim 6  wherein said second cylindrical casing is expanded plastic made of polystyrene.  
   
   
       8 . The apparatus of  claim 6  further having a sealed elastomeric bag within the second cylindrical casing.  
   
   
       9 . The apparatus of  claim 6  further having packed, high density particles as said load.  
   
   
       10 . The apparatus of  claim 8  further having a dye contained within said elastomeric bag.  
   
   
       11 . The apparatus of  claim 10  further having a membrane separating sid dye from said packed, high-density particle load within said elastomeric bag.  
   
   
       12 . A non-lethal shotgun round, comprising: 
 a cylindrical outer casing;    an ignitable propellent charge rearwardly disposed with said outer casing;    an inner cylindrical casing nested within the outer casing;    a wad disposed as a barrier within said outer casing forwardly disposed over said propellent charge but rearward of the inner cylindrical casing;    a sealed soft plastic bag composed of a uniform material disposed within said inner cylindrical casing forwardly located from said wad;    a packed, high density particle load packed within said sealed soft plastic bag;    a dye contained within said soft plastic bag; and    a membrane separating said dye from said packed, high-density particle load within said soft plastic bag.    
   
   
       13 . The apparatus of  claim 12  wherein the inner casing is expanded plastic made of polystyrene.
