7 Recommended Kids Thermos Flasks

7 Recommended Kids Thermos Flasks

So after another row about school packed lunches and what the kids were going to have (no it will never be chicken nuggets!) I posed the question on our Facebook page ‘What Kid’s Thermos Flask or Container should I use for the kids school packed lunches that actually keep the food warm?’

I had a lot of responses so I thought I’d share those with you here.

NB: The flasks or containers recommended could just as easily be used for a picnic lunch on a day trip or on a walk, as for a school lunch.

The single biggest tip about thermos flasks or containers seemed to be fill with boiling hot water first so that the flask is red hot before you put the hot food in. This helps keep the thermos (and your food, even at the bottom of the thermos) warm throughout the morning.

The second consistent tip was to fill the container to the top, so there is no cold air to cool the food down. This means you should try and buy a container or flask that fits what you want to put in it and doesn’t leave room to spare. I was trying to use an adult sized container when I clearly needed to use a kids one.

I think the key with a lot of them is that they have to be full I.e. very little space /air. If half full they seem to cool down much quicker.

Also make sure the food is really really hot before it goes in and is pre warmed.

Most Recommended Kids Thermos Flask

The winner of the straw poll was undoubtedly Thermos itself. The Thermos 184807 Stainless King Food Flask, Red, 470 ml to be precise.

The Thermos (which I’ve actually ordered myself to try out on all these recommendations) is not too big, not too small.

According to all the comments on my facebook page. It will keep food hot for a long time and definitely til lunch time at school.

Ideas for a Hot Meal at Lunchtime.

While I’m talking about what to put in a food container, it also occurred to me that I could ask about what warm food people put in their lunch bag and people came up with some great ideas for their lunch boxes.

Hot dogs are a great option. They can take the bread buns separately.

Hot soup is also a great way of getting veg into the kids.

Chicken Noodle Soup

Brown Rice and veg – wouldn’t go down too well with mine but might with some!
