Tankard, eh? Well, this one
was created mainly for beer, but does acknowledge a secondary use for keeping Doc-and-Roger-sized quantities of coffee hot:
And the main business of the chap who sells them (not
the random guy in the picture) is making "ultracoffee" - excessively-concentrated coffee made by scientific techniques in surplus lab equipment - so he should be cool with Roger using one that way
 Actually his main
business is being the "nuclear and laser guy" at UC Berkeley - so still pretty Doc-and-Roger-compatible really...
