cooking in the truck

Bummer! Yeah, need to remember that heat creates lower air pressure inside a container. After cooling it's hard to impossible to break the seal, unless you reheat to increase the inside pressure again.

 

Well now you know there is a tight seal!! Not as much worries if it tips over... Trying to look at the bright side

 

I've had it seal shut before and could just reheat, but this time it literally caved in the metal. I just figured it would have been designed with enough strength to withstand it.

 

I wonder if the could be considered a defect and can be returned for exchange?

 

Sounds like it sealed like a canning jar, then it cooled.

 

I've probably had it too long to return it. But it is definitely a design flaw. A piece of cookware shouldn't destroy itself just because you use it.

I bought it at an independent truck stop. I was going to give it to a friend when I start my new job next week. Now I think I'll just toss it.

 

Reminds me of when I sealed a brand new stainless steel thermos when I finished the hot tea at the summit of Mt. Rainier. Put it in my pack and forgot about it until I unpacked back in Seattle. The change in air pressure from 14,000' to sea level crushed it flat.

Whenever I drive the mountains in the west I always remember to "put a squeeze" on my plastic bottles. No need to get shampoo all over my shower kit or honey all over my dry food.

 

Lol or the opposite when you open your bottle of mayo or ketchup it shoots across the truck!

 

Very good advice. I will remember this.

 

Ive done that with mustard... ALL over a white shirt!! Sigh... I still do it at times... I guess I'm a slow learner!
