Does this straw leak when open or is there a valve? My kid likes to leave her cups on their sides (or upside down)

My grandson also left his open all of the time and we never had any leaks. Once he decided to start chewing on the straw and leaving little gashes in the plastic is when it started to leak some. I love this and if I had discovered them while he was still young enough, I would have had a cupboard full of them. They keep cold drinks very cold and hot drinks hot and we even added a clip to it so he could carry it on his belt loop, bike etc!

Hello, I can't speak for every bottle from Eco Vessel - but the one we use for our son does leak if left upside down. It doesn't leak to the point where water is gushing out - it's more like a slow drip. We put it in his backpack during school and if he puts it in the main compartment on its side, it does tend to leak. But other than that, it's a well made water bottle - my young daughter even knows how to sip out of it.

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

yes it does leak a little when turned on its side and the cap/straw is in the open position. The leak is several drops so if it is in a backpack or against paper, yes the paper will get wet. I use it as an adult drinking cup beside the bed - so it is great for me.

Yes, it is. Also, FYI, I am unhappy with the small hole on top, plus space around the straw that allow leaking if it tips or falls over. I read others note this & thought it would not be a problem for me, but it has been. Currently looking for one like this (I like all the other features.) w/o holes on top.

There is a valve piece. I only buy these for my two little guys. They are durable and do not leak!

You do not have to bite the straw for the liquid to come up. My grandson had no problem with this cup and has used it for about 6 months (he is now 23 months old). He still has this cup but his other plastic zippy cups with straws have been replaced with stainless cups.

The lid has a lever on it, it the lever is up it is open, down it is closed. Works fine used this several months and no leak at all. The lid screws on and you use it like any other mobile cup.

This would work well for a child that age. You likely will have to assist with opening/closing the lid, but your little one should be able to use the straw well. So far this has been the best product we have found for not leaking.

No. It leaks. I recently replaced this cup with "The Safe Sippy Cup" that I also bought with Amazon prime for 10.99 and I love the replacement.

Well, neither really. You push them on and there is a rubber ring that creates a seal. Does that make sense? It does create a nice tight seal that won't leak. However, on top you will either have the straw opening or the sipper side open. The plastic piece slides back and forth to expose one or the other, you can't have both sides closed. So, it's not going to leak on you as you drink, but you won't be able to throw these in a bag and go.

No. When the straw is in the closed position, a little gap opens up behind it so that even when closed, there is a small opening on the top of the bottle. If the bottle is on its side, it will leak. I have found the OXO kids twist water bottle to be more leak proof: OXO Tot Twist Lid Water Bottle for Big Kids (12 Oz) - Aqua

If the lid isn't on just right, the seal leaks very easily when the cup is tipped. It doesn't leak much upside down though.

I love mine and it has never leaked on me. When I fill it then go to screw the lid back on, the water pushes up the straw so I just drink more of the water then screw the lid on the rest of the way and I've not had any issues at all with leaking. I love mine and I use it EVERY day....

No. It's a plastic top that you pry (for lack of a better term) or pop off to drink. It's not difficult to open and close, unless a younger toddler is attempting to open it. It's attached so you just pop it open to drink and click it shut to close it. I use them everyday and haven't had any issues with spilling or leaking. I hope this helps!

Yes, the straw is not water tight (for obvious reasons), so it will leak both around the straw and through the straw itself.

I haven't had a leaking problem, but decided to experiment to answer your question. I filled it and put it on its side overnight - no leaking. However, when I vigorously shook it upside down, there was some dribbling. I've been very happy with this bottle so far.
