Safety container for transporting small quantities of explosives

Abstract

A safety container for transporting small quantities of explosives that iude a metal bottle that has a bottom and top section that are secured together with seal means therebetween and a cavity of the bottle has antistatic foam plastic material therein with a cavity at the geometric center of the foam plastic material for mounting or containing an explosive and the cap section has a relief valve for relieving any pressure that may be in the cavity of the bottle.

I claim: 
     
       1. A safety container for transporting small quantities of explosive and comprising a high strength metal bottle having a bottom section and a top cap section with said sections being removably secured together and sealing means sealing between the bottom section and the cap section, a cavity defined in said bottle and a rigid foam material mounted in said bottle and filling said cavity, said foam material having a cavity at approximately the geometric center of the foam material for containing a small container of explosive therein, and said cap having a relief valve means therein for relieving any pressures that may be formed inside the bottle, said rigid foam material being of such a material that when fully compressed it occupies no more than 5 percent of the volume of the cavity in the metal bottle. 
     
     
       2. A safety container for transporting small quantities of explosives as set forth in claim 1, wherein said valve means is a ball valve that is spring biased to a closing position and said cap having a port therethrough with a removable plug in said port for allowing a tool to be inserted through said port to unseat said ball valve. 
     
     
       3. A safety container for transporting small quantities of explosives as set forth in claim 2, wherein said rigid foam material is selected from the group consisting of polystyrene, polyurethane and polyethylene. 
     
     
       4. A safety container for transporting small quantities of explosives as set forth in claim 3, wherein said rigid foam material is such that it will not generate an electrostatic charge.
