  • Container base cup having reduced heat gain
    Patent number: 6474499
    Abstract: Base cup for receiving a container body bottom and for reducing heat gain to fluid contents in the container body. A passive base cup is made of foam and has a reflective layer on a majority of the outer surface thereof, or made of plastic, with an outer reflective layer, and optionally a foam layer. An active base cup serves to actively cool the fluid in the container, by including a compartment therein with a fluid that can be frozen. Again, a reflective layer and an optional foam layer extend over a majority of the outer surface of the cup. The reflective layer materials have a density different than the cup materials to facilitate recycling.
    Type: Grant
    Filed: May 2, 2001
    Date of Patent: November 5, 2002
    Assignee: Eastman Chemical Company
    Inventors: Michael E. Donelson, Lawrence A. Coppari, Stephen Weinhold, Marcus D. Shelby, Steven S. Duncan, Robert N. Estep
