It is the first one, I mentioned.
I think the others are, perhaps, more DIY throw it away and make another.
I recall his has lots of overhang inside the can and that makes me think there is too much room for airborne bacteria to settle into along with water.
It's easlily conceivable that many will cook ramen noodles in the can and that tells me there will be food stuffs that could possibly collect in those tine plases.
Hepa filters in labratories are used to filter out air born bacteria which are ever present in the air we breath.
Food, warmth and moisture can be present under the lip of the can when placed in your pack.
We will all remember the Wallmart grease pot with lip turned inward that everyone started crying wolf over.
Tinny's and smokeeaters rings are tapered so the ring can seat it'self over the edge of the can. That taper is on the inside of the can and has a lip on it that you can see and feel.
In this attached photo of smokeeaters rings applied and loose on the table you can see the lip/exposed ledge on the inside of the can.
I have one of tinny's lids to cut and show how it's made. Hopefully on Monday I can cut it with my dremel tool.
