Aladdin PMI 10-00760-000 Cook 'N Go Food Jar

I bought two of these at Target for my kids and I wish I could get my money back. They don't work at all. Food is cold after an hour. I should have searched Amazon for the top-rated thermos food jars before buying. I won't make that mistake again!

This is perfect can't be any happier with it..
You just gotta know that before you use it for your hot food, keep some boiled water inside it for like 10-15 minutes, and then pour the water, and it's ready to keep whatever warm food you want to put inside it. That's the trick!
Plus it comes with a spoon that can be stored in the lid!

I too bought one of these lunch bowls at Target and I can confirm that it indeed is not leak proof. My son started school and wanted soup. When I picked him up the teacher informed me that his soup leaked all over his lunch bag and book bag, making his folder and books all wet! There is a small hole in the slot where the take along spoon is (I assume for ventilation) and when I ran water on the underside of the lid I confirmed that it leaked through this hole. It also only does a marginal job of keeping food hot. When we sent spaghetti or pierogies they were only room temp come lunch time. Again I assume this is because of the small hole in the lid.
