Is there some way to close it, or will it spill out the drinking hole if it tips over?

There isn't any way to close the top, that said it has a very small slit like a Sippy cup. I found that only a small amount of liquid will come out if you would knock it over mine rolled over until it found an air pocket and then the slit is on top so that stops the leak. I would buy the product again

No! The lid has a hole that does not close (it's a screw on top, but you can't seal the actual opening where you drink from). Even if you did find a plug for it, I wouldn't trust the lid to stay put, and this is a glass tumbler, so it is VERY fragile. I accidentally dropped the lid and it shattered, so I had to buy a second one already. You need to be VERY careful with this item, but it is extremely elegant and for that reason I love it regardless :)

This is an old question but... I believe it twists so when they drop it, it won't just pop out. The tommy tippie cups are similar but the valve only pushes in so when my kid throws it from his high chair the valve pops out and drink goes everywhere. So its a good thing!

No, you cannot close the hole that is on top of the cup top, but the straw itself does have a plastic cover on it.

Yes! It does allow sipping while its in place. I don't think it is spill-proof. The lid is a little loose on top.

The cover will come off if tipped over. I keep coffe in mine. It seems to hold the flavor. The cover just slips on. But if u would want it more secure you could dab some wax from a glue gun or a tape of somekind going around the container. Hope this helps

Its a Screw on lid. Very, very tight, and the hinged cap for the drinking hole is tight as well. You could probably drop this from 10 feet and it wouldn't leak.

The top screws on, but there's a tiny air hole in the cap that your drink can leak out of. If you're sure your cup won't end up upside-down, you should be fine.

I really have no problems spilling. I do hold the end of the lid with my thumb just in case it decides to come off. Hope this helps you out.

Yes, even with everything closed tight, when I purposely turned the mug upside down, the coffee spilled out the sip area. Just secure the mug in a good spot.

The cap tends to pop off. If you held the cap in place it wouldn't leak, but I wouldn't trust it as a shaker.

It is not designed to function like that. It will leak or the cap will fall off if held upside down.

It unscrews. It took me a while to figure it out because the others lift off. If it gets stuck, gently use the part on top that closes the drinking opening like a handle and turn it to the left - remember this little saying - lefty loosey - righty tighty. It never fails me. Enjoy it.

It's going to spill if the top is not on, but other than that- no. If it's tightly closed then no

No, it's a pretty sturdy cup, I just tried to tip it over when half full and it didn't. We had this cup for about a year and never noticed it tipping over.

Hubby loves his but it will leak if it gets knocked over. It a very tight seal but the opening that you drink out of is open all the time.

My wife packs this carafe in her Tote daily. She fills it with hot filtered (ProPur) water to have at work.The carafe does not leak if tipped over as long as the cap 'push button' is not depressed. So, depending on how the carafe is packed, there is risk of spillage if the 'push button' is pressed down.
