It's a "Reefer" container, but they don't necessarily cool them down to
freezing. My guess is that to maintain freshness of the Doritos you're
far better off keeping them cool over long distances rather than allowing
them to get hot in a closed container.

You must be right. I left a bag out in the hot sun in the cockpit one afternoon
and they tasted oily and stale.....
