>>258401It has nothing to do with resealing the can. It has to do with portioning out a meal. This is the way field rations come in the military. I used to be a Army Cadet and we had to eat MRE's on our trips to places where we did not have access to anything that can refrigerate food and drinks. They came with a vacuum sealed thing of soup, energy bar, drink mix, and some weird cooking/cracker for dessert.
