Zojirushi Steel Food Jar, Medium, Black/Stainless

I refrigerated the jar for an hour, then filled it with ice cream and topped the ice cream with chocolate syrup. Four hours later my husband ate this treat and his complaint was that the chocolate syrup was frozen! Excellent temperature-preserving food jar, sturdy and good quality. Perhaps a note on the Japanese attitude toward Americans; all the warning labels on the jar were in Japanese characters except one; it was in English only and warned users to not pre-heat the jar (stainless steel) in a microwave oven.

Zojirushi is a great brand of insulated products and this is one of them. Lunch stays warm after several hours. Big enough capacity for a good sized meal.

It keeps my food warm for up to 6 hours.

You can never go wrong with a Zojirushi product and their food jar is no different! Keeps food piping hot (I do put warm water in it first to pre-heat) for hours and hours and doesn't leak.

Having used this container for months now it works exactly as expected. The only annoying thing is it is hand wash only. When I purchased it the listing information stated it could go on the top rack of a dishwasher. When I received it the paper instructions state hand wash only. For the price of the container it should be made well enough to machine wash.

These containers really keep the food warm. Made lunch for the kiddos and packed them at 6AM. By their lunch hour the food is still hot, six hours later.

I've become somewhat obsessed with insulated food jars over the past few weeks. I have no idea why. This is my 6th food jar, and all have been different brands. Most have been around 24oz, while one was 18 oz, and then this one, which is 17. So one thing I do notice is this jar feels and looks higher quality than my other jars. Not substantially so, because I think the Maxso and the Stanley are close, but this thing looks super nice. The polished still interior is beautiful and the handle feels great. Like every other food jar I bought, I put boiling water in it and took temperature every hour or two (or eight, when I go to bed). Simply put, this performed better than the ~$15 Hydrapeak 18oz (Zojirushi was at 122 after 14 hours compared to 104 for the Hydrapeak) and slightly better than the Hydra Gear 25oz I bought from TJ Maxx for $11 (was at 118 after 14 hours) But it did worse than all my 24oz jars. The Maxso and Stanley did the best at around 140-145 at this point, and the DaCool was around 135. Crucially, all of these jars are cheaper than the Zojirushi. My recommendation is to purchase the Maxso. It was $5+ cheaper than the Zojirushi, looks and feels REALLY nice (very close in quality to the Zojirushi), has a built in bowl and spoon, and has much more capacity despite not being much physically bigger. This is a really nice food jar! That's why I gave it 5 stars. I just think it's worth spending less for something better.

Nice open widemouth for easy access for food. The body of the container is all vacuum stainless steel and has a nice simple shape that is easy to clean, but the lid is problematic. The lid is fully plastic, which has two drawbacks: 1) not very insulating, and 2) it absorbs the smell of every food it has ever come in contact with. Since heat rises, hot food cools down pretty quickly compared to my kleen kanteen, which has a 18/8 stainless steel lid. But that is not nearly as bad as the smell of the lid after a few times of use. I've used this container no more than 5 times since I bought it, washed it obsessively, soaked it in vinegar, and it still smells like every meal I've ever put in there-- sweet or savory. I could not eat my blueberry oatmeal when it came out smelling like the kimchi/sesame oil that the container last came in contact with. The kimchi also stained the lid red. And by the way, the pressure release doesn't work. I was stranded on the top of a mountain with my container of food so tightly sealed I couldn't open the container, because it had cooled off and created a negative pressure inside. My final recommendation is, go with Kleen Kanteen.

Yeterli sıcaklıkta tutuyor. Almaya değer

The product is fabulous. Small but perfectly formed. I've made porridge in here and it's Perfect. Pour hot water off the boil into the container and replace the lead, leave for 10 minutes. Then, discard the water and add porridge oats and top up with boiling water (the amount of water depends on personal preference). You may need to experiment, how thick or runny you like your porridge. Place the lid back onto the container and leave for about 45 minutes. You will have creamy, delicious and heart-warming porridge. No saucepan to wash, no single-serving pot to dispose off, no cooking or even microwaving. Honest , healthy food and your bit for the environment. What's not to like. i have not test tried the container for carrying soup in and the temperature the retained. However, the porridge was piping hot (that said, I usually consume the porridge within two hours of it being prepared).

I like it thanks supplier. I like it as it helps a lot when I eat outside. The heat contain remain for 3-4 hrs.

At work I would never take food me even if I could heat it up using the microwave they had in the kitchen as it was hardly cleaned. I thought it would be a great idea to fatty the thermos and see if it actually worked. I cook salmon with a bit of rice and vegetables the night before work. I microwave it at home the morning just before leaving. I would say it keeps food hotter than warm but it’s not piping hot it’s just right.6 hours later.

Kids love it for school lunch. Keeps foor warm and does not leak. Very easy to clean, as all peices come apart. I usually hand wash it but it is dishawsher safe. It holds enough for hungry teenagers.
