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 force transfer device serves as an integral part of a level indicator for both viscous fluids and lower viscosity liquids. The viscous material itself forms a seal between the interface region of the force transfer device and the inside wall of the fluid vessel. Vertical stabilizing elements may extend outward from the force transfer device.
