Keeps food piping hot for hours – brilliant for school lunches or work!
I bought this Thermos food flask in Cranberry Red for taking hot meals on the go, and it honestly lives up to the reputation. The insulation is exceptional. I pack hot soup or pasta at around 7 AM, and by lunchtime (5 to 6 hours later), it’s still piping hot—not just lukewarm. The 470ml size is the sweet spot—compact enough to tuck into a backpack, yet roomy enough for a generous portion. The folding full-size spoon hidden inside the lid is such a clever touch, meaning there's one less thing to forget in the morning. The wide mouth makes filling and eating directly out of it really easy, as well as cleaning up afterwards. Most importantly, it’s completely leak-proof—no spills or oily messes in the bag whatsoever. The deep red finish looks lovely too. Absolutely worth every penny for winter lunches!

Fantastic. Hot Hot Hot!! Multiple uses for those corporate people living in hotels.And the metal spoon was a great bonus at work
In a word - Fantastic. (Thermos Food Flash 470ml Blue) bought direct from Amazon on Prime 1 day delivery. What can I say, I mean, just read the other reviews for more detail, I dont write reviews often but I just HAD to chime in and confirm this was indeed a good... GREAT buy. I'll try to be brief. I've used it for 3 days so far. The flask keeps the food hot, simple. And the metal spoon is great. It folds away neatle and is STRONG too. None of this plastic spoon rubbish. And it looks good on the desk too (The blue one is the one I have). Just to give a better idea than, its great, its hot. Heres some timings. Day 1 8am - Add hot water as per instruction to pre-heat. Removed after 10 minutes and took to hotel breakfast restaurant. 8.30am - Hotel Microwaved my diet food soup and put into flask. Off to work. Approx 1pm - Opened the flask. The food was hot!!! Great! Day 2 Ddint use it in the day, but thought I would be inventive. Im in a hotel, limited and bought some of those typical hot-dogs-in-a-tin (mine were in plastic wrapping but same thing). I WAS going to have them cold. BUT, then I saw the Thermos flask on the desk. *Lightbulb moment* Broke the hotdogs in half, threw them into the flask, boiled some water, and put the lid on. Watched some TV, about 10 minutes later, opened the flask, got the foldable spoon out, and fished out the hotdogs. They were piping hot!!! Fantastic. Boil-your-own-food-in-a-flask at the hotel moment. Normally the hot water into a mug wouldnt stay hot enough to properly heat the hotdogs, but this worked great! So needless to say, im even happier now! Maybe this will even work for instant noodles. Day 3 This time I was too rushed to pre-heat the flask, and I went straight down to breakfast. 8.30am - Hotel microwaved my diet food soup and put into flask. Off to work. Approx 2pm (So an hour later than the pre-heated day 1) Opened the flask. The soup was hot!! Like hot as in had to sip it a little hot. Not warm, hot! If I was going to be picky, I wouldnt say steaming hot, but none-the-less. But what do you expect, it was actually microwaved food, so I didnt think that would stay as hot as actual cooked or boiled food. And I forgot to pre-heat the flask. But this STILL exceeded my expectations. Any questions, or anything you want me to try with the Thermos (within reason) leave a comment, and I'll see how I can help.

Another great thermos!
I’m a big fan of thermos and would rate their products highly in terms of expectation and actual product, quality and value. The Pros- I’ve now had 4 of these flasks and have found that you can use them twice daily and they hold their heat around four to five hours. you can use six hours however, you will notice that the temperature is cooler. The Cons - One query is that they have altered the inside of the lid and I’m left wondering what the little plastic bit is see photo. However, this would not detract from recommending the product. Cleaning - recommended for hand wash only hot, soapy, water and a dish or bottle brush is all you need. After about two months use of daily use, the inside can tarnish and look unsightly. I have read this in a number of other reviews. The solution was recommended to me by my Dad. Simply put a single dishwashing tablet into the flask body and pour on very hot water. For example 80 to 90 degrees. No need to use the lid. Fill to top of brim. NB if it is too hot after many times, you will unfortunately the bottom of the flask may become detached so be careful of water isn’t too hot. Product rating - I would give it 4 out of 5 on the basis that it will only last a year or two I have found that the bottom of the flask can detach after many uses and cannot be put back together again , the other issue are found in the past is that the rubber around the neck of the flask can loosen with time and can be very difficult to put back on. Leak ability. I have noticed that you do get a good Seal however I would say that I struggle sometimes putting the top lid on , I think this is something that could be explained as it’s not mentioned in the instructions. Star Rating - I would give this four out of five and would have no trouble in recommending it most highly. Manufacturing recommendations - To improve base of flask so that it does not detach after so many uses and also neck of flask where rubber ring can become loose and detach. Many thanks for reading. I do hope this was helpful. Kind regards.

In general a nice flask
Compact, nice finish although I’m a bit cautious with it as I’m not convinced the paint won’t deteriorate. Functions well, keeping food warm. I bought two. This one and another well known brand. They are much of a muchness. Both are good flasks. This one (as mentioned before) has a different quality finish. Aesthetics? Yes but I am concerned that it won’t stay the course.

Best purchase
Why didn't I buy this sooner! I hate work canteen/microwaves so unless I have a sandwich or similar I don't eat full meals. Well this is brilliant. I have greek yogurt topped with frozen berries and seeds etc and it is just about perfect after 5 hours sitting in the car ( warm day too!) I have tested this for the last few months. Also, soup. I bring to boil put in in this and bring to work. Again leave it the car and after 5 hours it is still very hot. I had homemade berry crumble today with yogurt and it was still cool ( only had it in the fridge an hour after cooking it). I think this is the best purchase I have made . Perhaps the heat/cool won't last a long time but I am prepared to replace it if so. Usually I just handwash so unsure if using dishwasher.

Love this Thermos King Food Flask ... what a beauty ... especially in the Red!
Love the colour, love the size and shape ... what a beauty! After i've stopped gazing at it, i did test it with coffee and realised that becuaes that has milk it won't keep hot for so long as soup or hot water for example. Over the next couple of weeks i'm going to test it with various foods / drinks that i want and get a feel of timings, but overall I'm thrilled with this especially as locally there have been quite a few power cuts and it's taking a little while for things to be fixed. In the meantime having a drink or flask of soup at the ready, if there is a blip i know i've got a hot drink during that time. Alsoi haven't used it yet, but there's a cute folding spoon that i'm sure will be useful for any hot meals i have. I like the suitably wide neck for filling, especially for meals, and easy for cleaning.

Perfekte Thermodose für essen
Es ist die zweite Thermos King Dose, die ich gekauft habe. Die sind stabil und langlebig, selbst wenn sie auf den Boden fallen. Wenn das Essen richtig heiß eingefüllt würd, halt es mehrere Stunden heiß, es hängt allerdings auch davon ab, wie flüssig die Speise war. Je flüssiger, desto länger hält es heiß. Was auch super funktioniert, ist das Kalthalten von Eiswürfeln für den Transport, wenn man im Sommer draußen kalte Getränke mixen will oder eben nicht ständig in die Küche rennen. Da schmilzt ebenfalls stundenlang nichts. Die Dosen halten auch nach Jahren des Gebrauchs dicht. Also für sie neue Dose kann ich das natürlich nicht nicht sagen, aber die erste, baugleiche Dose ist nun mindestens acht Jahre alt und ständig im Gebrauch und funktioniert einwandfrei, obwohl inzwischen mal der Boden abgegangen ist. 0,5 p könnte für manche für Mittagessen vielleicht zu klein sein aber es gibt sie ja auch in größer. Die Öffnung könnte etwas größer sein, aber ist auch okay.

Good product
Perfect, keeps the soups very hot for hours, only liquid things keep them hot, no solid. I dropped another Thermo same brand when I was washing it and stop working probably got a leak so treat it with care.

Sağlam olanlarından alın :)
Ürün güzel bir ürün,ancak kutuyu açtığımda hasarı olduğunu görüp iade ettim.İade süreci sorunsuzdu ve bir kaç gün içinde kredi kartına iade yapıldı. Aynı üründen ve bir adet de yeni serisinden olmak üzere farklı bir pazaryerinden 2 adet aldım. Kullandım ve oldukça da memnunum. Satıcı ile temasa geçip ürün gönderimi öncesi kontrol isteyin..
