## Description

From the manufacturer

Review: Well made food flask with generous capacity - I bought this Thermos Stainless King Food Flask for the young one’s lunches and it has been brilliant, well worth the cost. The 710 ml capacity is generous and easily holds a good portion of soup, stew, pasta or a hearty lunch, so there is plenty of space for a proper meal rather than a snack-sized portion. Build quality is exactly what you would expect from Thermos. It is well made and feels robust. The stainless steel construction with the gun metal finish looks smart and holds up well to daily use without showing scratches or wear. The lid screws on securely and seals well, which is reassuring when it is being carried in a school bag. Heat retention is excellent. I preheat it with hot water from the kettle for around 10–15 minutes to warm the flask properly, then add the food. Using it this way, the contents stay piping hot for hours, which makes a real difference. The wide mouth makes it easy to eat straight from the flask with a spoon and also makes cleaning much simpler. It also works well for cold foods or drinks if needed, and there is no condensation on the outside, so bags stay dry. I am very happy with this flask and, as long as the young one does not lose it, it should last for many years to come.
Review: Great for Healthy Homemade Pot Noodles - Love this wide mouth food thermos and am so glad I paid for a good brand as it works so efficiently. Mainly using it for "instant" ish noodle bowls. I pop in my home made broth powder, dehydrated veg and dehydrated egg pasta noodles, add boiling water and leave it for about 10 to 15 mins giving it a shake from time to time. I then pour the contentd which are now perfectly cooked, into a bowl of I'm at home or eat them directly out of the flask if I'm in the go. The wide mouth makes it easy to fill, pour and clean. It goes in the dishwasher but to be honest, it's so easy to wash straight after use that I will probably just hand wash. Portable and when filled with soup it was still very hot after 4 hours. Great quality.

## Questions & Answers

**Q: Can you fit a small child in this? Asking for a mate!**
A: Only if the child has not been preshrunk on delivery and you wash in too hot a temperature when the child might shrink.

**Q: Sometimes when you use a flask it's leaves the food with slight metallic/plastic aftertaste. Does this occur with this flask?**
A: There is no after taste food tastes as good as you'd have on a plate and still piping hot

**Q: Could i store ice cream in the flask and place it in the Freezer for when i go the Cinema?. :)**
A: Thank you for your question. Since this is a vacuum insulated flask, placing it in the freezer will not affect the temperature of the food inside. However, in this case, we would recommend chilling your flask before adding the ice cream with chilled water or ice in order to ensure that your ice cream does not melt once transferred into the flask. After that, you should not need a freezer at all!

**Q: Is it spill proof? Will it leak in my bag whilst walking?**
A: I have found it to be completely spill proof providing you screw the lid on properly first. I take it to work with soup in and it hasn't leaked yet!

### ⭐⭐⭐⭐⭐ Durable, fit for purpose, longlasting &:high quality
*by W***Y on 14 December 2025*

I purchased my twin grandchildren 0.40 L Thermos food flasks when they started secondary school. The flasks are still going strong, but larger upgrades were needed as the grandchildren are now at college & require a more substantial meal. As with the earlier version, the 0.70 L flask is perfect. I filll the flasks with boiling water for as long as possible (sometimes overnight) prior to putting their meal in. 5.5 hours later, the food is still piping hot. A few days ago, my granddaughter didn't get chance to eat lunch & ate it in the car on the way home. 9.5 hours after filling the flask & the meal remained piping hot. The key to keeping food hot is to adequately pre-heat the flask & fill to the top. The larger size weighs much the same as the smaller, older model The flask doesn't leak. I've purchased many Thermos products over the years & can hand on heart say that I've never experienced a problem with any of the products from this company. They're my go to brand & I recommend them.
