CONTAINER BASE CUP HAVING REDUCED HEAT GAIN

摘要

Base cup (30) for receiving a container body bottom (15) and for reducing heat gain to fluid contents in the container body (12). A passive base cup is made of foam and has a reflective layer (44) on a majority of the outer surface thereof, or made of plastic, with an outer reflective layer, and optionally a foam layer (46). An active base cup (60) server to actively cool the fluid in the container, by including a compartment (66) therein with a fluid (68) 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 (44) materials have a density different than the cup materials to facilitate recycling.
