Cylindrical piston assisted blending vessel

Abstract

A container/transport system for a viscous material includes a container for the viscous material and a transport conduit for transporting the viscous material. The container includes an outer rigid wall; an inner flexible bladder, the inner flexible bladder containing a viscous material; and a conduit connected to the inner flexible bladder to introduce a fluid into the inner flexible bladder. The transport conduit includes an outer rigid wall, an inner flexible bladder, a volume between the outer rigid wall and the inner flexible bladder containing a viscous material, and a conduit connected to the inner flexible bladder to introduce a fluid into the inner flexible bladder. A valve controls a flow of fluid from a fluid source to either the inner flexible bladder of the container or the inner flexible bladder of the transport conduit.

1 . A transport conduit for transporting a viscous material, comprising:
 an outer rigid wall;   an inner flexible bladder, a volume between said outer rigid wall and said inner flexible bladder containing a viscous material; and   a conduit connected to said inner flexible bladder to introduce a fluid into said inner flexible bladder;   said inner flexible bladder increasing in volume in response to introducing fluid therein such that the volume between said outer rigid wall and said inner flexible bladder decreases causing the viscous material to be evacuated from the transport conduit.   
     
     
         2 . The transport conduit as claimed in  claim 1 , wherein the fluid is a gas. 
     
     
         3 . The transport conduit as claimed in  claim 1 , wherein the fluid is a liquid. 
     
     
         4 . A transport conduit for transporting a viscous material, comprising:
 an outer rigid wall;   an inner flexible bladder, said inner flexible bladder containing a viscous material; and   a conduit connected to said outer rigid wall to introduce a fluid into a volume between said outer rigid wall and said inner flexible bladder;   said volume between said outer rigid wall and said inner flexible bladder increasing in response to introducing gas therein such that a volume of said inner flexible bladder decreases causing the viscous material to be evacuated from said inner flexible bladder.   
     
     
         5 . The transport conduit as claimed in  claim 4 , wherein the fluid is a gas. 
     
     
         6 . The transport conduit as claimed in  claim 4 , wherein the fluid is a liquid.
