I was just packing my bag for a Dartmoor mountain biking trip tomorrow, when I suddenly thought of something. Filling a small drybag up with your food and then blow it up with air. release enough of the air to roll the lid down a few times and seal it. The dry bag won't compress enough to squash the stuff inside. I doubt it would last a long time, but might work for a day, saves the weight and bulk of a clip lock container.
I'll try it out tomorrow and see how it works!
