Was at the local hardware store and found these. For less then the cost of those small spill proof containers you can buy these http://www.amazon.com/Tic-Tac-Fresh...F8&qid=1379955997&sr=8-3&keywords=tic+tac+200. They work perfect for holding different size rivets. Plus you'll have 800 tic tacs; win win in my book.

Juicy Fruit Gum Containers

My wife came home with some Sugar Free Juicy Fruit Gum containers that I have saved for the same purpose as you. Rivet storage containers. The top has two flip lids, a big one to add rivets and a small one that should be about right to dispense rivets. http://www.amazon.com/Wrigley-Juicy-Fruit-Groovy-Fruity/dp/B0055IWHKI

I haven't compared the price nor how well they work, but hey, she bought them and was going to throw them away, so to me they are free!

I use empty clear water bottles. I can see the rivets inside and the small caps mean if I drop one only a few will spill.
