are they leak proof?

No. I ordered 2 sets and about 3 of the ones that I got came home in my kids' lunches unopened because they were stuck closed. My kids, their teachers, my husband, and I could not open them no matter what. So actually those 3 were leak proof, but also unusable as a result! The remaining ones that we are able to use will hold mushy food, but if you put soup or water in them, the'd leak if they were tilted sideways or upside down. The lid and bottom pieces have no thread like a screw would - the lids are slightly wider than the bottoms and just fit over the bottom piece.

I have never put liquid in these containers so can't really say if they are leak proof. I have used them for grapes and cut fruit pieces and they have worked very well. They do close pretty tightly if that helps. Fortunately my now 8-year-old daughter has always been able to open these containers herself.

No they aren't leak proof. I use them for dry snacks, strawberries, apple, or grapes, but nothing with any juice.

No. They do not have a rubber gasket that makes them leak proof; however, they work well for things like thick salad dressings, ketchup, mustard, mayo, etc. These are designed to hold small portions of food inside a tiffin to keep them separate (like say you have tomatoes you want to put on a salad or something like that) and are not really intended to be filled with liquid.

No. If I pack nut butter or olives I place the container in a zip lock bag to avoid leaking. I don't want to put my husband's lunch in plastic, however, so the stainless is not harmful to him and easy to clean.

I do not believe they would leak. I found that the cork was quite secure. I, however, did not put any liquid in them when I used them. Hope it works for you.

No, I didn't have a leaking problem. My does not work. I believe they cannot be plugged in all the time however I'm not sure.

Yes, they will leak. The membrane or seal is good, however we experienced leaks. These are great for practice and game days.

My son uses them and is very hard on them. They've never leaked. I also use them and have not had any leaking issues. Very well made containers.

I only use them for water, but simply put - if you close the lid and turn it upside down nothing comes out. So I would assume no matter what liquid you put in there it would not leak out.

Yes, as long as you screw on the tops good, they're leak proof! I've put them in my purse sideways multiple times and nothing leaked out. They're great bottles, the perfect size. I've saved a lot of plastic bottles by buying these.

No. They will leak if laid on the side. These jugs are not completely airtight.

I never had an issue with them leaking and I used them everyday for six months. The only problem would be if they are overly full then frozen, the top won't stay on then. Just don't fill to the very top.

Yes. However I would not recommend them. They started to leak after few uses.

They are in the spigot. We've used it a few times and have not had any leakage problems.

Yes they are leakproof. We've never had a problem. I carry one in my purse. HOWEVER, folks are right about the caps. a few of mine are starting to crack, possibly from over tightening. I'm going to get replacements caps because the bottles are excellent.

Yes. There is no "waterproof" side which is what I don't like about them. When you leak, it goes right through. I am unable to use these.

Yes. I have found these containers to be leak proof. I was pleasantly surprised to see how much food they can hold. So far, they have held up nicely, and I use them frequently.

I have had these for going on two months and have not had a single leak. I use them for our two little girls almost daily!

Yes they are water proof, but to a certain extent. You dont want them getting soaked all the time.

Leak proof about100% for mine, currently about seven month. I had another one started leaking after 1.5 year.
