i think you should use aluminum foil for sure and that stuff on the inside of a quilt. then on ther outside use black paint or somethong so the heat will go inside of the thermos. Tis should work. stick a hole in the cap for a thermemetre aswell so you will be able to test it! this is the bes awnser that you might get.  for the commercial, if you really want you can say something that would go with your design. like saying that it is always hot!! in the commercial you can say the good qualitys that it has and model it! lol!!!
