I don't know. It seems weird to market coal in a small enough container that would use this size of foil seal. Although, Coal is the main ingredient in Black Powder and Old Ben mines used Black Blasting Powder for a long time. Here is a writeup about the president and CEO of Old Ben Coal Company speaking about eliminating the use of this dangerous explosive.

It sure looks like a seal to a bottle but I think they are thicker than expected for that use. Perhaps accommodating blasting powder?
I am trying to picture them on each end of a cardboard tube and these are the end caps somehow. Perhaps holding matches inside. What is also weird, I can't find this exact logo with coal underneath inferno.
If they marketed a product, you would think there would be some artifacts and collectibles remaining from them. This is what is nice about these forums, some day another person will search
Old Ben Inferno Coal and this post will be the ONLY visual evidence they can find to match their artifact with.
Here is the patent to add to the list of clues and the patent page with a little info on the company...http://trade.mar.cx/US71657550/
