I really hope we get a video out of this to see how bad it actually is and how much "pressure" is needed for this.

> Incidents/Injuries: Thermos has received 27 reports of consumers who were struck by a stopper that forcefully ejected from these containers upon opening, including complaints of impact and laceration injuries requiring medical attention. Three consumers suffered permanent vision loss after being struck in the eye.

That's an awefully large amount of reports about this. I wonder what about the design makes it a rocket compared to what I would assume is a pretty standard design?

> The Stainless King™ 470ml Vacuum Insulated Food Jar is the ultimate day to day companion to keep your food at optimal temperatures. Keep fruit fresh and vegetables cool for up to 14 hours while you take on the day. For your favourite soups, pastas or stir fry, they’ll stay warm for up to 9 hours – ideal for taking last nights left overs. You can be sure that your food will be perfect for consumption at lunchtime after you pack it in the morning. The wide mouth makes it easy to fill and clean, and comes crowned with a stainless steel lid that doubles as a serving bowl. Plus, it comes with a handy stainless steel spoon that fits neatly into the lid compartment.

It's meant for storing food, for anyone who is confused why someone would be.

I'm a little surprised it's a recall - is there some expectation that it should have pressure release? Can you not sell simpler products legally?

Isn't the point of a thermos to put "perishable and fermenting foods" in it, like coffee or tea? Like this could totally have been me, like make a thermos-full of coffee one day, then forget about it only to come back to in some weeks just to open it and have one of my eyes blown off

My steam cleaner recently was recalled and sent me a new cap with a built-in pressure-locking valve. People were opening it too early and getting burns. Heat and pressure can be very dangerous.

> I 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.

> I'll promise I won't be a dumbass with them :(

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?

   The malfunction is due to multiple models of containers missing a pressure relief function in the center of the stopper.

I would have thought they could design the screwtop so that it would relase pressure before fully disengaging the lid from the flask.

I've never seen a thermos bottle with a relief valve. Not sure if all manufacturers in Europe have nonexistent QA or if it's just not a thing that's commonly needed since you can't heat the contents up in there anyway (it's not like an insulated water boiler, which does have a release valve). Never considered that someone might leave food in there long enough to build up explosive pressure. Feels a bit like saying a missing cat detector function in microwave ovens points at them having no quality control

I would assume that it was some cost optimization that led to the removal of the pressure relief.

It was bramble beer for me. Put a load of lovely ripe brambles in a batch of homebrew beer, one of the little pithy bits on the inside wedged up against the bottom of the airlock, and overnight the pressure built up enough to pop the cork out and spray the ceiling with brambly splats and beer.

Tasted okay though.

My mate brewed his bramble beer by putting his brambles through a juicer and only adding the juice and pulp, because he's cleverer than me and has a certain amount of foresight.

The one without the relieve valve is nicer to use because it's (much) easier to clean. Source: I've cleaned these things pretty much every weekday for the last 2 or 3 years.

The one that's not recalled has a pressure release button
