do lids seal to prevent spilling during transport?

Frankly i have not used them during transportation. There is a lid side slot which would slide in to prevent the lid from opening and its pretty tight. I think they should be fine as the lid closes tight, not sure if all liquids would be contained in it, but thicker ones yes they would be in it ~Rahul

Yes it prevents, it is a thermostat means keep warm your food for long time.

It should keep them spill free once they r locked properly.. 2 out of the 3 locked well......the smaller one had some issues with its lid not aligning with the lid slot.... they are otherwise well made n does what they r supposed to do, keep food warm that is....

I haven't used them for transport yet, but they seem spill proof, to be safe line the top with aluminum foil and cover with lid

I haven't had any problems, although I usually don't transport liquids in them. This is my second set and I just love them. This set seems to be made better. The lids lock much better then the previous set.

It keeps warm for atleast 4 hours but it is not 100% leak proof, liquids might spill if there is a lot of movement during transportation.Try to keep it straight.

Yes, there is a thin seal on the inside of the lid. It doesn't cover all the lid.

The lid is a push on lid with a seal on it. I have had severial of these cups with lids like this and have had no issues.

I believe so but have yet to do it. I love the sealable lid for transport (not while cooking). Good size for groups.

After owning these containers for a year+ I would say no, there isn't a liquid tight seal on any of the joins between containers or lids. It's best for transporting non liquid food.

I have had a little issue with the casserole lids not having a tight fit after being used in the microwave. I have not had any leaks taking them to work, but I don't really challenge the seals either as they are always in a lunch box and not bounced around very much. The cup lids still fit tightly.

No. The lid does not seal, it is loose. My one complaint. Otherwise they are nice.

The lid does not seal securely but if I think that the contents in the casserole will leak out, I cover the dish with foil and have never had it leak when transporting it.

Yes, the lids seal up nicely. I just tried it out to confirm and water doesn't drip out while holding it sideways or upside down. The lids seal it up tight and no spills.

Mine had lids as in the picture but did not have caps that would seal them closed.

I have reused the lids and rings repeatedly for the last couple of years (4?) with no problem. They are holding a seal.

Yes, the plastic/silicone seal is what secures the lid closed. Liquid will come in contact w/the seal if help upside-down.

I agree the lid appears loose. However, I've had nothing spill or even leak during traveling.

They are pretty sturdy and the lids fit securely. I have mixed oil and vinegar and taken them to work, and nothing leaks.

I shouldn't leak at all if you have the lid snapped on firmly and the little vent hole cover snapped into place. It's a rubbery lid that seals pretty tightly and takes some effort to sort of "peel" it back off the cup when you are ready to eat. I've never had any spillage in my fancy tote bag I haul lunch in.

No- the lids stay in place well, but it's not leakproof, so if there is any liquid, it will spill through. Best to keep flat

All of the lids I have fit very tightly. On the large round ones, I have to pry them off with a knife handle. They don't leak or spill at all.
