Transport packing made of plastic and method for the manufacture of a transport packing

Abstract

Transport packings made of plastic are usually manufactured as stable hollow bodies and serve to transport fluids. Due to electrostatic charges building up on the plastic bodies, electrical charges frequently arise, which represent an explosion risk. In order to exclude such risks, the plastic packing includes electrically conductive polymers. These polymers may be applied as paint to the outside of the plastic packing.

What is claimed is:  
     
         1 . A transport packing, comprising a body made of plastic and including an electrically conductive polymer.  
     
     
         2 . The transport packing of  claim 1 , wherein the body is a stable hollow body.  
     
     
         3 . The transport packing of  claim 1 , wherein the body has a volume of more than 450 liters.  
     
     
         4 . The transport packing of  claim 1 , wherein the body is made of polyethylene.  
     
     
         5 . The transport packing of  claim 1 , wherein the body has a seam point.  
     
     
         6 . The transport packing of  claim 1 , wherein the polymer is applied to the body in the form of a paint.  
     
     
         7 . The transport packing of  claim 1 , wherein the polymer is applied to an outer surface of the body.  
     
     
         8 . The transport packing of  claim 1 , wherein the polymer is applied as a net-like layer.  
     
     
         9 . The transport packing of  claim 1 , wherein the polymer is applied as translucent layer.  
     
     
         10 . The transport packing of  claim 1 , wherein the polymer is selected from the group consisting of doped polymer and semiconductive material.  
     
     
         11 . A method for making a transport packing, comprising the steps of: 
 subjecting a surface of a plastic packing to a process selected from the group consisting of flame treatment and corona treatment; and    spraying the plastic packing with a material containing an electrically conductive polymer.    
     
     
         12 . The method of  claim 11 , wherein the sprayed plastic packing is arranged in a metal cage.
