That sucks. I have both and the ones with the pressure relieve valve are a pain in the ass to clean. You have to pull out the rubber inner thingy, you can't get a towel inside the hole that thingy goes into, and in general the rubber thing gets lost easily. I wish Thermos would send me a few of those 8 million stoppers, I'll promise I won't be a dumbass with them :(

That's not very empathic of fellow people who might just have mistakenly forgotten food in the container.

It's not like they were intentionally using this for brewing some illegal substance or misusing it in a way specifically forbidden in the manual or obviously unsafe (e.g. removing a magnetron and all of its protections from a microwave to make pretty wood carvings).

I wonder if they track how many people are sickened by the difficult-to-clean valve, because I bet it's a lot more than 3.

Luckily I got one of the valveless models, and you bet your ass I'm keeping it. Maybe I'll stick an "open away from face" label on top or something, but I'm not about to go increasing my risk of food contamination.

Can you also guarantee with absolute certainty that you'll never forget them anywhere another person who's unaware of the contents or the danger could find them?
