Abstract
A material transfer system for storing, transferring and dispensing viscous material, such as fluids and liquids, includes a material containment vessel with an upper region incorporating a motive force and a bottom region with a material ingress and egress opening. A diconical or other shaped force transfer device is located in the material containment area. The force transfer device is an energy transducer when the material containment is filled with highly viscous materials, such as adhesives, sealants, mastics or lubricating greases. The system's performance can be improved by applying a surface treatment to the wetted surfaces of the system to change the physical properties at the fluid/vessel interface.
