Do they seal tightly? For instance, can I bring hot soup to a sick person without my husband's crazy driving making it leak all over the car?

The thermo dish is not sealed but has a locking lid so if its in an upright position it won't leak.

The lids are the same in term of leakage. I use saran wrap before I put the lids on. That works for me.

It totally works for that as well! I put sandwiches, rice, yogurt and it seals the food in its compartment. There is no leaking whatsoever. However, I only put food in that doesn't need warming or heating up as I prep lunches the night before and put in fridge.

We own several of these and have never had one leak. They fall over in the back of vehicles while offroading and get knocked around, but as of yet, none of ours have ever leaked. As long as you seal it properly it's designed not to leak.

I'm not sure, as I've never tried it. They do seal well without much effort on your part though.

They have a rubber seal around the edge and the top vent snaps in securely. Not ideal for soup but for most meals or leftovers this is perfect. The only way I have seen them leak is if something catches the side clips and opens it or weight is put on the top, which would most likely crush the whole thing in the process. With the raised insert you can either keep items from getting soggy or steam vegetables in the microwave, remember to top the top vent.

Yes, it's a really good seal. I've put it in my backseat, closed and full and it's never leaked at all.

If you do, I'd recommend putting them in an additional vacum type sealable bag.There have been reviewers who have had problems with the seal of their packages over long term.I would keep them in an emergency kit or part of my work pack that I take in and out of the car each time as the house is a much more controlled atmosphere - but that's just my preference.

I haven't tried to use them in this manner but, to be honest, I think that would be asking for trouble. These lids are tight, but not bulletproof. You should probably try to find something where the lid screws on tightly, rather than pushes down to form a seal. My opinion only.

If you tighten them well, they shouldn't leak. I have noticed that overtime the gasket wears slightly and the seal isn't perfect but tends to leak only when the cup is dropped.

No, it doesn't, and they are not leak-proof, although I do carry them in my lunch bag sometimes. They work well for thicker items like a smoothie or yogurt, but I wouldn't recommend them for liquids like juice or soup, unless it's just going in your fridge.

I use them for Limoncello, and they seem to seal pretty tight. I would say, yes they are air tight as they are placed on their sides with the liquid against the top and show no signs of leaks.

There is a rubber seal on the inside of the plastic lid. Some of them still leak. I certainly would not call them airtight.

If you get them sealed properly they are very good at keeping a good seal. There is a little plastic tool on the front that one uses to seal with. I love mine;=.

There are two containers that have screw on lids with gaskets. I use those for things that might leak. The other three are just snap on lids and would probably leak if you used them for liquids. I have found that the top two are plenty of storage for my more soupy food items and I stick to drier things like cut up fruits and such with the other containers and just keep it upright. I haven't had a problem with leakage that way.

They are very well made and seal tightly. I'm not sure they are air tight, but they are leak proof.
