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.

The straw lid does leak. It is really designed to be upright. It's the one downside.

I just held it upside down and it did leak. But the lid has bite marks in it from my kids... I bet it didn't do that until the bite marks.

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.

Hi no external straw for a child to drink with. However excellent bottles and do minimize airflow. The only negative is replacement parts are not available. Inside there is a white cap, the internal state and a plastic circular thing that connects to internal straw which is easy to lose.

While holding it upright it does not leak. I store mine frozen standing up in a cup in the freezer and when you hold them while eating they do not leak. Never tested them laying down or inverted - didn't want to take the chance!

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.

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.

Child has to suck to get it out, but not super hard like some sippy cups we've had. However, after having ours for about six months, the no spill valve has broken and it pours out. I could just replace it with another valve, but I probably won't bother since I don't let him walk around the house with it to spill it anyway. We only use ours for water because I'm not fond of things that need a bottle brush to reach inside, I never feel like it gets it clean enough anyway. I suppose you could put it in the dishwasher however, which would be easy enough. Overall, I like this sippy cup a lot and would recommend it as one of the better, if not the best sippy cup we've ever used.

There is a rubber gasket on the inside of the lid where the cup screws into. I accidentally kicked the cup when it's full. The only spillage comes from the hole on the top that the straw goes into and that is very little. One other consideration with these cups is a straw discoloration. I take my cup to work everyday filled with ice tea. After a few months the clear part of the straw size gets a brownish hue. Perhaps a solid colored straw would work better. Otherwise I love the cups and would buy them again.

No valve my daughter doesn't struggle while drinking her juice or milk. I love this cup especially for my little preschooler. My daughter is only 2 years old and she seems to have no problems with this cup. I also bought matching back pack and lunch box. I say go for it

No, once you remove the straw, the hole is wide open. However, I've knocked the full cup over several times with the straw in, and almost no liquid spilled. And there's no valve or anything on the straw. So I doubt you'd spill very much at all if you knocked it over WITHOUT the straw in, if that's what you're worried about.

The only time ours have leaked is when the valve hasn't been inserted the entire way....which usually happens after my son throws his cup 3 or 4 times.

There are no numbers on this one so you have to calculate the amount of water or milk you put on it. There is absolutely no leaking with this sippy cup, even when upside down. They do come with an extra seal if you want to make sure but I have never used those and never had a problem.

yeah if you shake them up side down they will leak but my kids dont shake there cups upside down so i didnt see that as an issue for me. but any sippy cup will do that. there really is no such thing as a 100 percent free leak cup i wish there was.

The straw is open but it requires the child to pull like any other straw. The cup is nice my only complaint is that my son usually prefers to drink from the bottom of the cup lol, and once the cup is open and the straw exposed the liquid usually falls out. But the cup is very strong and there's a place for adults to press if the child is unable to pull properly from the straw. Hope this helps.

There is a little drinking slit and that is never closed - so it would leak if turned on it's side or upside down.
