Best flask for soup or stew lunch portion?

[AbsentmindedWoman]

What do you find good? I want one that won't leak (obvs) and isn't too bulky, that will keep soup warm for about 5 hours.

My kids have the Thermos Stainless King Food Flask. It comes with an integrated spoon and keeps the food hot really well.

They’ve been using them for about three years and never had a leak.

Amazon sell them for about £20.

We also use the Thermos king, would recommend.

Yup, a thermos. Absolutely love mine.

Yep we have the same
Kids love theirs, they take curries, hot dogs, pasta

Thermos here too.
Definitely worth the money

Unanimous recommendations. MN should get an advertising cut from Thermos!

We have several of them ☝️and they've been amazing. So long as you don't look too closely at the end result you can put literally anything in them.
They've been redundant over the summer months but I've just stopped them for the salad pots in the cupboard

Brilliant, thank you. Want to bring soup from home instead of forking out for Pret etc.

They are very easy to clean as well.

Agree with nona about them being easy to clean. I think they say not dishwasher safe IIRC, but my "bung it in and see" approach had worked fantastically over the last three or so years (except the colour has peeled a little on a couple)
