Refillable material transfer system
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.
1. A refillable system for transferring material, the system comprising: a vessel having a longitudinal axis, an inner wall, and an arrestor, and a first end having a material inlet and outlet manifold; a force transfer device disposed within the vessel, the force transfer device including, (a) a crown; (b) a cylindrical member having a longitudinal axis substantially parallel to the longitudinal axis of the vessel, wherein the cylindrical member includes an outer wall that is parallel to the inner wall of the vessel, and (c) a conical thruster attached to the cylindrical member; the arrestor of the vessel positioned at the first end of the vessel and configured to conform to the shape of the thruster; and
a treatment applied to the vessel's inner wall and arrestor to change a friction of a moving fluid at the inner wall and arrestor; and
wherein the treatment is a sandblasting to increase the surface roughness of the inner wall and arrestor.

wherein the treatment is an application of an agent between the inner wall and a bulk fluid therein, and an application of the agent between the arrestor and the bulk fluid therein;
wherein the agent is a binder/tackifier.
