Review: Thermos 16-Ounce Stainless King Food Jar


Thermos 16oz Stainless Food JarWhile the Foogo Stainless Steel Food Jar was top of the food jar list it is fairly small and not very adult. The larger 16-Oz Thermos Stainless King Food Jar is extremely popular with thousands 5-star reviews on Amazon.

This Food Jar has impressive features and would be an absolute “must-buy” were it not for some horrible quality issues that pop up on some of the units.


  • Stainless Steel interior
  • Tight lid keeps heat f0r 7 hours, cold for 9
  • Wide mouth and lid that doubles as serving bowl
  • Vacuum insulated: remains cool to the touch and no condensation or water rings
  • Easy to clean
  • Compact with Low profile
  • Folding spoon that clips into lid
  • All plastics are BPA free


The Stainless King Food Jar performs brilliantly and all reviewers report it to keep food hot for 7-8 hours. It is easy to eat from, easy to clean, and it packs well in a bag or lunch box without leaking. If you are interested in cooking with a Thermos then this is the only food jar that was recommended by several “thermos chef’s” as viable to cook with.

Which brings us to negatives.

Probably the most glaring fault of this unit is that the glue that holds all the bits of the body together just stops being “glued”, and it falls apart. This is a regular quality issue and spoils an otherwise excellent product. While Thermos and Amazon have a returns policy, this is disappointing. A possible lighter note is that the glue issue has not been mentioned in reviews over the last few months so perhaps it has been attended to. This is an excellent product and if you get a good unit, then you will be more than happy.

Another issue with the Thermos Stainless King Food Jar is that the cover can be difficult to unscrew when there is warm food inside also, it is hand washable only and only comes in one color.


What Amazon buyers are saying

-“Only used it a couple days, but so far works great!  … when I’ve eaten my soup 5 hours after putting it the thermos, the soup was just the right temp for eating … the outside of the thermos doesn’t get hot, so my cold lunch items stay cold and my lunch bag won’t melt..”


-“Perfect size for soup or side to lunch. Spoons can reach bottom and hot stuff stays very hot. Fits nicely in my lunch box. Would recommend to anyone trying to eat healthy and pack a lunch or a picnic. Easy to clean as well. I would love more colors”
