Not food but these are some of the things I re-use:
Containers from the wet mop pads. They hold 2 stacks of 5" squares/charms and have a clear lid to see whats in there.
Plastic gum containers have a flip up lid that pins can be dispensed from.
I scrubbed out a baby wipes container, lined it with foil, and I stash my chocolate and jelly beans away from my DH. He has never used a baby wipe so it is not likely he would check what was in there.
