Just to make sure I understand correctly...

1)The thermos is stuffed with a crap load of charcoal.

2)It's "breakproof."

3)It breaks.

4)Major mess.

I didn't know thermoses were stuffed with charcoal. Neat.

The charcoal forms a barrier to radiant energy barrier:

FWIW, if you want a Thermos bottle get one:

I've always thought that Thermos bottles are pretty amazing

You put hot stuff in and it stays hot. You put cold stuff in and it stays cold.

HOW DOES IT KNOW

I put a scoop of ice cream and a cup of coffee in one a few years ago. The coffee got cold and the ice cream melted. I want my money back.

Especially now that I know the charcoal did it.

It was just confused. Next time, try adding RitolinÂ®, too

I didn't know thermoses were stuffed with charcoal. Neat.

I never realized they filled the space either. Anyone know if all the thermoes are filled, or just some? I though the glass and stainless versions were empty, relying on the shape of the chamber for strength. The patent mentions lower levels of vacuum being used in a thermos, so I don't really understand the need for fill material anyway.

I wonder if Thermos brand is filled? I notice the patent belongs to Aladdin-Satnley, filed in 1990 while Thermos has ben making stainless steel vacuum bottles since 1966.

Either way time to check the ones I have at home. One has no handle, and the other has plastic bands around the thermos that the handle attaches to. The article/pictures don show how the handle was attached, or how it came off.

Looking at the patent Chuck linked, I can see why cleanup was so hard.

United States Patent 5252408 wrote: charcoal or activated carbon black when used as the solid particulate material is utilized in a particle size having range of 0.4 to 1.0 microns. Similarly, when silica gel is used as the solid particulate material, a preferred particle size is in the range of 1.0 through 10.0 microns. .... the particles of silica gel would be compressed to a density lying within the range of 6 to 12 pounds per cubic foot ...the preferred density range of charcoal or activated carbon black lies in a preferred range of 16 to 25 pounds per cubic foot.

That's a lot of very fine powder to go floating through a house!

Maybe the title of the post should be changed to "If you have an Alladin Termos". I just received this response from the Thermos company (not the maker of the Stanley containers):

Chuck,

Thank you for your email. Thermos does not use charcoal in their insulation. We
use a vacuum seal between two layers of steel.

Thanks,
Thermos Customer Service

So, apparently if you want to avoid the "charcoal smoke", buy a Thermos brand container.
