Can I use those to send to school? In another words, will they leak inside the lunchbag?

We try to always keep them upright, but we have never had issues with them leaking when on their side. I'm not sure if that goes for when they are on their side for an extended period of time

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.

I've been using these for a couple of years now. I've found that it doesn't leak if the lid is on tight, but will seep after an extended period on its side. So for example, if I find one under the dining room chair several hours after lunch, I will usually find a small amount of water under it. That said, I do send these to school with my little ones.

You can totally pack a lunch with this! The lid screws as tightly or as losely as you wish. If screw on all the way its water proof, and when child ready to drink, start to screw to come off or loosen and that will control the speed od the flow for little ones learning to drink. Barely lose and slow flow almost off and fast flow.

In my opinion, yes. I work for a school district and I use them. I would not object if a student wanted to use them. They do not bleed through the paper which is why I like them so well. Before purchasing them, I would check with your district.

i have used them in the freezer and also sent them to school with my 4yr old, and they have not leaked or cracked. I make sure they are not filled to the brim and the food is moveable so that they don't explode and keeps the seals in place

No, they don't; they are simply inserted and would most likely spill in the lunch bag.

I dont think so. The cone shape of the dish would not lend itself to pre-fab lids, and they don't come with custom lids. Still they are sturdy and fun, kids love them, (i gave them to 10-year olds) and could be reasonably sealed with foil or plastic. I woouldn't wrap them for a lunchbox, though, if you cared about spillage.

I would say yes, as you have to fill them in an upright position - I use a freezer safe cup, or the fluid will leak out around the cap, before the are frozen.

Yes and yes! I used them in our microwaveable bottle sterilizer daily. As for leak proof - they're about as leak proof as a sippy can be. Occasionally little droplets come out if they are dropped from a high chair or thrown across the room but I would highly recommend these cups.

Yes, they seal well enough. But I would put them into a bento, not into a purse.

Yes, they do not leak at all I purchased two. One for veggies and the other for dressing. My 10 year old has never had a leakage problem with these and she uses them daily for school. I wash them by hand. No dishwasher!

They Don't leak... But you need to make sure you "snap" the lid close. if you don't hear the "snap" its not closed. :-)

I use this in my daughter's lunch box and nothing in there needs to stay really cold. She eats only a few hours after it is packed. I can tell you that it is not still cold when she gets home about eight hours later. If these were used with the lunch bags that go in the freezer (which don't even require a cold pack) I have no doubt that everything inside would remain cold all day!

The gel is a bit liquid-like, so it may leak out of a bag, but if you put it in small plastic Tupperware/Rubbermaid packages and put pinholes in the top, it would work and not spill out.

I have used these in my lunchbox and have not had any leakage. I am using these as replacements for the black lidded rubbermaid containers that are no longer available. I like these and will order again.

Yes! I take my lunch in one of these every day and put it at the bottom of my backpack. I don't baby my backpack when going to and from work so it moves around a lot and I have yet to get a leak from these at all.

I don't think they would leak through, I think you would probably see it through though. I recommend the Pilot Frixion highlighters and gel pens. They have great color sets and they are eraseable. Love them.

Yes, definitely. The lid has a good seal and you can tighten it down very tight. I leave these in my backpack which is laid on its side under my desk all day and have never had a leak.

not sure...they don't seal completely. Just a drawstring top. The bag material is probably fine enough.
