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.

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.

Quality, no included spoon.
A great food flask, keeps my food warm for at least 8 hours. Personally I use it for pasta, for work lunches. Was disappointed to find that this did not include a spoon in the larger size, despite the AI assistant telling me it does. Good value for money, the durability and build of the item is polished and will surely keep for a long time. It is quite a weighty product so keep that in mind if intended for long treks with a flask full of food. It’s easy enough to clean, but may be harder if one does not own a dish brush.

Durable, fit for purpose, longlasting &:high quality
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.

Ottimo prodotto
Il thermos è spettacolare! L’ho comprato per mio marito che è costretto per motivi di lavoro, a pranzare sempre fuori. Cercavo un prodotto che mi consentisse di fargli portare un pasto sano e mangiarlo caldo! E non potevo scegliere di meglio. Preparo il cibo la mattina alle 6 e alle 14 (ma abbiamo constatato che arriva anche oltre) resta caldissimo. Le zuppe addirittura restano bollenti. Se si ha l’accortezza di riempirlo per 10 minuti con acqua bollente e poi una volta svuotato inserire il cibo caldo, la durata è assicurata! Se preparate la pasta consiglio di scolarla molto tempo prima dei minuti indicati perché mantenendo il calore, la pasta rischia di scuocersi. Lo consiglio vivamente.

Perfekt!
Die Flasche hat eine perfekte Größe, hält 100 %ig dicht und richtig lange heiß. Ich mache mir am Vortag so gegen 18 Uhr ein Gericht für das Mittagessen auf Arbeit und habe dann gegen 12 Uhr noch richtig heißes Essen. Das Gefäß ist gut zu säubern, lediglich die Gummidichtung nimmt schnell Farbe und Geruch der Mahlzeit an. Auch zum Wandern super geeignet!

Super Größe
Am besten gefällt mir an diesem Behälter die Größe, die ich auch bei keiner anderen Seite so finden konnte. Ich habe bisher immer erst heißes Wasser in den Behälter gegeben, um ihn schon vorzuwärmen, während das Essen in der Mikrowelle ist. Morgen um halb acht befüllt, sind Reis und Hühnchen mittags perfekt warm. Wenn der Behälter voll ist, hat man wirklich eine große Portion, die ich eigentlich nie brauche. Praktisch ist das allerdings für Leute mit größerem Appetit oder wenn man Lebensmittel mitnimmt, die einfach mehr Volumen brauchen. Die kleinere Größe von Thermos hatte ich im Laden mal gesehen und die erschien mir einfach zu klein. Mit der 710 ml Version bin ich rundum zufrieden. Ausgelaufen ist bisher auch noch nichts und man kommt mit der Hand gut rein, um einfach saubermachen zu können.
