There's a new series of containers on the market from a company called Lock and Lock. The containers are polypro with snap locks on each side and a water/air tight seal. I picked up a couple at the local grocery store for $1.87 each to try out for PSK use.
Mine measures out to 6.1 x 6.1 x 1.8" and it's listed to be capable of holding 2.5 cups of whatever. Basically, it's a sandwich sized container that easily fits in a BDU pocket, large jacket pocket, waist pouch, haversack, or pack.
I've stuffed mine to nearly full capacity this am, and here's the contents list thus far:
