Dug this one recently...Embossed twice around shoulders "College Inn"...Have dug another type that used a crown closure...but can't locate it presently to post a pic.
Was this a soda ?
A couple other people asked about that bottle here, but no useful information was given:

i have seen these bottles in clear and green. they were always refered to as a soda. the ones i've seen had the regular soda cap top. that opening reminds me of a molk or fruit juice opening.
Glass Monkey...that's interesting about a possible Chicago connection. I have dug these off and on here over the years...mostly in a local town dump...Makes it appear they were distributed locally, perhaps ??
I think the large one is a key top. I don't know if they could hold the soda preasures.If not the broth sounds more likely. I'll go hunt for the key top thread.
edit
It was called PRIOF and I'm still not sure about preasure but it's looking like it would.
