Latest Patents

Duncan is credited with 1 patent: “Container Base Cup Having Reduced Heat Gain.” The invention describes a base cup that receives the bottom of a container and helps limit heat transfer to its contents. One version uses a foam cup with a reflective outer layer, while another uses plastic with a reflective layer and, optionally, foam insulation. An active version includes a compartment for a freezable fluid to cool the container’s contents. The reflective layer can use materials with a different density from the cup, supporting easier recycling.

Career Highlights

Duncan’s documented patent contribution focuses on container insulation and cooling. The design combines passive approaches, such as reflective surfaces and foam, with an active cooling option.

Collaborations

Duncan is associated with Eastman Chemical Company. Marcus David Shelby and Robert Noah Estep are identified as coworkers.

Conclusion

Steven S. Duncan’s patent presents practical approaches to reducing heat gain and cooling fluids in containers, with attention to both performance and recyclability.
