If you turn the bottles on their side to store them, are they leak proof, or is non-spill only in upright position?

I always keep mine upright i have had them tip over in the car with no leaks but all in all keep up right

they are water tight must use only on largerlip type 55 mm.not screw type bottles that are 43 mm size.lip type picture seal on or upside down no drips

I'd say yes but, I do use a plastic grap around the cap with the heat gun to completely seal it.

Yes, they are safe to keep the water in the bottle whether they are on side or even upside down.

Haven't tried liquids, but it has a good seal and if you don't tempt fate by storing it on its side, I don't think you will have leaks.

My bottle also leaked when stored horizontally. So I keep it upright in storage now. Teflon tape might also work.

Yes, the lids seal up nicely. I just tried it out to confirm and water doesn't drip out while holding it sideways or upside down. The lids seal it up tight and no spills.

The lids fit snug. The dividers are deep. As far as leak proof, I'm not sure what you plan on doing with them. If closed and left upright I don't see them leaking.

They are pretty much in the middle - my hair conditioner is super thick so I give it a shake upside down and then it's pretty easy. I travel every week and have searched for bottles that don't leak - these are fantastic. If you kept them on the 'full' side I don't think you would have any problems.

The closures are pull-up type and seal very well. Bottle can be turned upside down and will not leak. Bottles are NOT soft sided and cannot be squeezed. Very durable and feel smooth in the hand.

Not advised. The cup has no lid, and the bottles have a small airhole in the caps. This prevents tipping them up past a certain angle

No. It's a twist off top. I've never had one spill or leak, but I can see how it's be possible.

They haven't leaked and I have stored them horizontally. Of course, just make sure the lid is properly screwed on :). These are great bottles and I love that I can grab one "to go" for a snack for baby by just screwing a nipple on instead of the cap!

I cant promise that they are leak proof but definitely leak resistant. If you knocked one over upside down their might be some slow seepage but not much and no real mess to clean. The heavier the liquid the safer you are. Water itself might leak out but probably not soup!

I have had some leaks when liquids were in them and they were shaken upside down. IMO, I'd not take them in a backpack unless closed in a ziploc.

They have a small flat spot on the bottom. Works fine. Never had one spill.

Yes, it is leak proof. Keeps liquids hot or cold for hours. Bought them as gifts for friends. That's been over two years ago and they still use them almost daily.They are awesome and sharp looking.

No, at least not when I've used these bottlestoppers. My suggestion is to just make sure you push the stopper all the way in before placing the bottle on its side.

I have five of these containers and have found that a couple will leak when on their side. It doesn't matter how much I tighten the lid, they will leak. It's not a serious problem for me as I can leave them upright.

Hi Jennifer, I use the stoppers on both cork & non-cork bottle types. As far as the positioning of the bottle, I never tried to store sideways. Lisa
