Storing espresso beans/grounds at work..

[tchariya]

I'm finding myself itching for espresso more and more throughout the day. My morning 20oz isn't tiding me over til I get home. So I have hot plate in hand, incoming 3-cup mokapot and delicious beans. Problem is, there is no decent tabletop grinder I can keep in my desk at work. I don't want to have to resort to manual grinding (tiresome!). So I think I'll resort to grinding a weeks worth of beans into a tuperware and sticking it in my desk.

Is this what you would do?
Should I grab something like a sealed jar of glass or ceramic material?

Or maybe I'm missing out on a grinder that would do well at work.
