Collapsible Travel Trailer Collapsible Coffee Mug?

Collapsible Coffee Mug? - collapsible travel trailer

I can not be found. I need this because I take many science classes in school. I prefer my coffee at home (cheaper) ... that the use of the same cup of coffee (well, cheaper than using paper, or other). In any case, it would be nice to have a cup of coffee and put it in my backpack during the school laboratory (which is not allowed) to each type of beverage or food. I was putting my cup of coffee in my bag so far and I wonder if it is not (something like a modern folding travel cup of coffee to celebrate the old fashion pill? Or where one has a given when there is no such thing.
