The boxes, tins, and cans are okay for storing patches when out hunting (need for a new patch only now and then) or for storing lots of them over a long term. But the lids get in my way when I'm out for a day of shooting. I like to be able to shove my hand in my bag, get my fingers on a patch, and put it to use without having to find the can, pull it out, open the lid, fish out a patch, etc.
So, I take a piece of wax paper and fold it up to make an open topped envelope. I put the patches in there, and put it in a small pocket sewn against the back of the bag (on the inside of the bag), with the open top facing upwards. That lets me get my fingers in there and scrounge up just one patch, without messing with lids, and at the same time keeps the patches from lubing up the inside of my bag.
