This is interesting. It could work if, like you say, you sanitize the heck out of it. But, tell you the truth, I wouldn't use it. Do you have a glass jar of jam, jelly, spread, juice, etc? Any food you have in a glass jar could be emptied and you can use the glass. Actually, you could use a beer bottle (or two), just cover them with foil and you should be good to go!
