Product Description

The Thermos 'Stainless King' range, developed by Thermos to blend the latest vacuum insulation technology complete with retro styling. The 0.47L Stainless King Food Flask is the ideal choice for people on the go. Built to last, and enhanced with an integrated spoon and lid large enough to directly eat from.

Thermos' vacuum insulation technology virtually eliminates temperature change within the food container by creating an airless space between two stainless steel walls.

Helping you make healthier and more economical meal choices for when you are out and about.

Before you use, pre heat or pre chill by simply filling your flask with hot water for hot food and cold water for chilled food. Allow the flask to rest for a few minutes with the lid attached, empty the water after a few minutes and then fill with your chosen food item.

    5.0 out of 5 stars Superb!! 9 Nov 2009
    Colour Name:Blue
    This is the first time I've ever written a review about something I have bought, but this Stainless King is worth the effort to do so.

    I was looking for a small, compact but effective food flask for the forthcoming winter months in order to allow me to warm up during work and break the monotony of the sandwiches and salads. After looking at the reviews on here I decided that despite the slightly higher price tag than I had originally thought of paying, the 'you get what you pay for' mantra would be very relevant when I was sitting there with cold soup.. NOT what I was hoping to achieve!

    So I made a decision and parted with my money... and boy am I pleased I did!!

    First outing today and after warming the flask as recommended with boiling water for 10 minutes, my bubbling hot tin of Spaghetti Bolognese (from a well known pickle manufacturer) went in and the lid was firmly screwed in to place at 7.15am and the anticipation started.

    1pm arrives and I sat down with my work colleagues and plonked the flask down on the dinner table and with confidence unscrewed the lid, to be met with steam..that's right ..'steam'. I tucked in, straight from the flask and unbelievably it was actually red hot, and in some parts was 'almost' too hot to eat. Needless to say, some flask envy ensued.

    The other great thing about the flask is the size of the opening. It's easy to fill, eat straight from and to clean... it's all good.

    So if you are looking for a compact, easy to use and most of all 'effective' food flask... this is the one you want.

    5.0 out of 5 stars A Fantastic product 8 Dec 2008
    Colour Name:Blue
    I bought this food flask a couple of weeks ago and have used it every day since. It is just the right size for tins of big soup, tins of spaghetti, stews etc. It keeps everything piping hot for hours. There is a telescopic spoon in the lid which is perfect. It even stayed intact when it fell out of my bag and down the whole length of a coach and down the stairs to the door!!! I am even going to buy another flask for my husband as it is perfect for these cold winter days.

    Definately a 5 out of 5! Sandra

    5.0 out of 5 stars works 6 Aug 2013

    Good bit of gear I haven't really tried it over a long time but over 2-3 hours it keeps my soup or haggis warm and warm haggis by the river on a cold morning is one of my joys in life.

    3.0 out of 5 stars Good product, but faulty lid 28 Jan 2013
    By Harriet
    Colour Name:Blue|Verified Purchase
    The flask works well. However, when it arrived the sliver part of the lid was not glued onto the black part of the lid. I wanted to return the flask for a replacement, but this was not possible, according to the Website. I decided to return the item as faulty, and buy a new one, but it had gone up in price substantially since I had ordered it. So I super-glued the lid together, which is working fine for the moment.

    5.0 out of 5 stars Great product - if you follow the instructions! 22 Jan 2014
    Colour Name:Blue|Verified Purchase
    Great product. Nicely made, robust. Does what it says - i fill it at 06:30 and the food is still piping got at 12:30 when i have lunch.

    Couple of things though to those who say it doesnt work

    (1) make sure you "prime" it with boiling water first for at least five mins.
    (2) make sure you dont let the food contents touch the inside of the black plastic screw cap (ie, dont overfill)
    (3) make sure you keep it upright, ie, dont let the food touch the lid.

    A small amount of heat dissipates through the plastic lid, and this is normal, BUT if you dont follow the above your food will not retain its heat. Simples.

    3.0 out of 5 stars Not as impressed as others! 29 Nov 2009
    By Dom
    Colour Name:Blue
    I've had one of these flasks for a few weeks now and have not found its performance to match the description although it is acceptable. Generally I have put soup in it at around 07:00, and had it for lunch at around 12:00. I always pre-heat the flask with boiling water, and heat the soup as hot as it will go. I have experimented with varying pre-heat times and heating the soup in the microwave and on the hob.

    Thermos claim that it will keep contents hot for 7 hours. After 5 hours the soup is still at a reasonable temperature to enjoy though not piping hot, but I would not leave it to 7 hours. It is perhaps fair to point out I empty the soup out of the flask into a bowl to eat rather than eating directly out of the flask, so this would account for a small amount of heat loss. It is notable that both the stopper and the outer cup/lid get very warm quite soon after filling, so clearly this is the weak point on the flask.

    I have since bought a Stanley 0.5l stainless steel "vacuum food jar" and tested it against the Thermos in a boiling water test. The Stanley performs better by a few degrees and is cheaper.

    This food flask is simply amazing and saves me so much money!

    I bought this food flask before starting university as a way for me to save money. Being on a student budget, I find it difficult to find a nice, filling yet healthy lunch which I can buy on campus - and if there are healthy options available they are very over priced. This food flask is the perfect solution for me! I now take home-cooked, healthy food to university every day!

    I had read the previous reviews and it seemed to be a good product, so I bought it with fairly high hopes. After the first day of using it I was surprised as to how well the flask kept my food hot. I now take this food flask with me to university every day and have used it for nearly every type of food: curry and rice, pasta bake, lasagne, stir fry, soup, etc. Even quite dry dishes such as lasagne are kept warm (you should add a little boiling water to dry foods to keep them moist and to stop them from drying out in the flask - and this keeps the food warmer for longer)

    Before I go to university I fill my flask with boiling water and 10 mins later I empty out the water and fill the flask with my microwave warmed food. I find this is enough time for the inside of the flask to be heated by the boiling water so that your food stays warmer for longer.

    On some days, when I have been in a rush, I have filled my flask with microwave warmed food without having pre-heated it with boiling water and when I have come to eat my food at lunch time the food was warm but not hot, so I recommend that you take the extra time to pre-heat it in the morning.
