New Midwest Gas can fail

[RayIN]

A few years ago I bought a 2-pack of these 5G plastic cans. I didn't use them until last summer. I refilled one yesterday and this morning it was empty. Evidently the heat we had last summer caused an over-pressure situation in the can, and the seam around the center that joins both halves split.
This is yet another problem with the newest safety rules for home gas/fuel cans. I called Midwest CS and was told "that cannot happen, our products are designedd to withstand temperature changes, thank you for purchasing our product." (abbreviated conversation)
That was my last purchase of Midwest products.

No-Spill brand are heavy duty and very well made, plus they work great. But when I leave gas cans empty, I tend to loosen the lids so they don't blow up or suck in from vacuum as it deforms them, sometime permanently.

I keep the nozzles loose on my gas cans empty or full. I have not had one crack since I started to do this. I keep them outside in a plastic container.
