resealable cans

 We can do it with tupperware, why not aluminum?

If this idea's already baked I won't be surprised, but here goes. Canned foods more often than not need to be refrigerated after opening if you don't use them right away, but you still need to cover them with something (like that cling wrap). Why not figure out a way to reseal them, maybe with a lid like the ones on tennis ball cans? This could help keep cans of pop from going flat, too.

       I vaguely recall seeing this somewhere, but I have alzheimer's from consuming things that have been stored in open cans for too long, so I can't remember....

       There's things like soda covers through those tacky mail-order companies

       There's an annoying little old lady in our suburb who flogs these things door-to-door, along with little saddles to hold the TV remote and guide, and 1200-piece toolsets for $99.95 and... and.... and.....

       I've heard that often the contents of a can can have adverse reactions to the can after they've been opened and exposed to the air, so you aren't supposed to leave them in the refridgerator in their cans for very long. For example, pineapple will deteriorate the tin in tin cans through a chemical reaction, leqving you wth tainted pineapple. Maybe this is why resealable cans aren't baked.

       There is a certain type of can opener that cuts along the seam around the edge, rather than punching through the metal on top, leaving a lid that can be replaced and nearly airtight, but as fatmess said, it's probably not a good idea to store things in them...I'll see if I can find a link...<net.rummage> Ok, I give up. I found plenty of links for buying them, but none for how they work. It cuts horizontally through the folded edge around the outside of the lid, keeping it from falling into the food, and allowing you to put it back on for temporary storage.
