if it melts, does it leak?

Mine haven't leaked yet and I even had them as treats in the car for a trip but they were eaten withing 20-30 minutes anyway. I also suction the contents into the lid to keep excess air out.

Not sure if would, we didn't tip them over. I know when they are empty and on their side, any amount of pressure sends the top flying like a rocket! Hope this helps.

I just put water in it, put the cap on, and shook it. It doesn't leak. Unless you squeeze it, then it will leak.

We haven't had any leaking. But in the tipsy hands of my two year old it will spill out the top if the lid is off. :) we enjoy them outside!

Generally and 90% of the time the answer is yes. If you have ice with cold liquid in it for an extended time it will if you bring it into extremely muggy or hot weather. Otherwise it will never sweat or spill.

Yes. I bought this thermos mug so that i could put it in a backpack with important papers and bike to work. As long as it is screwed on correctly, it will not leak. I've have it for two years without any flaws. It is indestructible and worth the high price.

It will leak if it is tipped with some force. Shaking it at an angle will also result in spillage.

Yes, but you have to push it down a bit to snug it up. I haven't had a problem with mine leaking once I do that.

No this thing does not leak. There is a rubber seal around the mouth that keeps it airtight.

No. It might keep it warm?? If you melt it before you put it in the device.

Yes, it is leakproof! However, when using this cover your ice will not stay solid as long as the original lid. Make sure when using this lid that the bottle stays upright.

No it doesn't melt it is hard plastic I put my 425 degree straightener in it right after using it and haven't ever had a problem

As long as the lid is on tight and the lock switch is flipped, yes. I haven't had any problems with mine leaking.

No, it should not leak. Please align and distribute the gasket equally around periphery before locking and operation.

Yes, the liner is a hard plastic insert that will not leak and it is antimicrobial so melting ice is no problem unless it tips over.

NO!! We soaked ours in hot water for almost three months, had to replace the plug and handle, coat the seams in wax, and it still won't hold liquid. This stupid thing still leaks, just slowly. If you take the plug out of it, drips in a almost constant stream. We followed the directions, but to no avail. It also took three months to get it. Sorry, but this is an interesting conversational piece, but not really functional.

Not sure I understand the question. As long as the lid is screwed on, it does not leak but, obviously, if you remove the lid and turn it on its side the contents will pour out.

No. The plastic would melt as it is made of the same material used for plastic cutting boards.

It does not, it doesn't melt immediately but if you left it for quite sometime it melts. It would be nice to have a unit that dropped it into a freezer then continued to make more. We do really like it though...great for camping!!

They have been known to leak. I have discovered that if I heat the lids before tightening, the plastic will become malleable and I can tighten them further. Then, when they cool, the plastic shrinks and the lid will be tighter and not leak.However, just for picking up and shaking a drink, I have not had a leak with something like that. When they leak usually it's a very small seep.
