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.

No but it does leak from the straw and from the threads where the top screws on.

I haven't had a problem with a leaky straw. Whatever is left in the straw from the previous sip will come out, but that's been it for us. It is not that hard to get water out as long as you don't have it filled up all the way

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

the lid screws on and you have to flip the straw upright to drink. I have not had any problems with leaks and use daily and throw in my lunch bag. I like this bottle because keeps smoothies cold through the afternoon.

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.

If you hold it upside down and shake it a lot it will leak, but we've had no problems with normal usage. If it falls over nothing comes out. You may get a drip or two if you hold it upside for an extended period of time, but I don't know for sure. We haven't had any problems with normal day to day usage and we've got 3 kids (age range of almost 2 to almost 6) and they each have one.

Yes. Mine leaks horribly! Even after she drinks out of it and I relieve the pressure. The milk always creeps up the straw. I sent the company an email about it and am awaiting a response.

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.

No valve. It stops the liquid flow by twisting the cap, pulling the drinking portion of the straw into the lid and pinching it so that no liquid can flow. So, there is a good shutoff and it doesn't leak. But there isn't a valve on 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.

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.

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.

Nothing comes out if the child turns it upside down and shakes it. The only problem we've had with it is that liquid just comes up and out when it's closed tightly. Pressure issues? Other than that it's a great soppy cup and I can just give baby the cup without worrying about her spilling everywhere.

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.
