What is the intended purpose of the clear (ish) silicone "sleeve" that fixs within the plastic spout of the sippy cup?

I think that makes it spill proof but limits the flow and flow is already just from 4 dots. So we take them out, easier to clean that way too. I haven't seen the bottle leak without it

I think it's supposed to be a spill proof spout. I don't use it because I needed my sons liquids to just flow so he learns to drink properly with the spout stopping the flow. HTH

You insert this when you want to be able to toss the sippy into a bag, etc to make it spill proof.

This is to keep the liquid from leaking. It is still possible to drink with this, though it is somewhat difficult. We cut a slit in it and it was better, but now we don't use it at all as she's a bit older and sets it down.

It slows down the flow (for younger babies/toddlers) and makes it more spill proof. My kids can't get enough flow with it so we never use it in this cup. Only issue is when tipped and the piece not inserted they do spill very easily and sometimes the liquid shoots out.

Yes, it should come with a silicone cap. For the record, both my nieces love these cups (and they were HARD to wean off the bottle!), although I recommend a sleeve, as they can get chilly for little fingers.

Yes and No. The rubber type plastic is like a sleeve for the glass bottle. However the valve is a plastic piece, much like just about every other sippy cup on the market.

Yes, it's a small sippy hole like in a disposable coffee cup lid. It will fit a regular straw through the hole (flexible silicone lid) for drinking cold beverages too.

they may have changed the design for the regular cuppow lids? mine has an oval opening, as i purchased it quite a while ago.i don't think it should make a difference as far as drinking goes. you might want to try contacting cuppow.

There's a silicon ring that goes inside of the top which will prevent the bottle from leaking.

I'm not positive. I use this on the tall and shorter sippy cup style. It was great to get my son off the " bottle". But I do need to replace them frequently and I can only find them on amazon.

I can not see or feel any silicone between the glass sides and the metal base. It appears as if the sealing is done below the metal heating element so it does not come in contact with the water.

i think you question is, can you buy just the straw top and screw it onto the bottom of the sippy cup. I dont know, but I think the sippy is a little shorter. I've never seen just the top. I once tried to buy a replacement straw for the straw cupt, but you had to buy the whole silicon piece and it was $7.

Hi Sarah.. I believe there are different versions of those cups, if there full round it may work... take a look of the little bumps the plastic cap has... this one has 2 wholes to fit with to bumps... some others caps has 3 and it there is your case... may have some leakage issues ;) I hope that this helps

It pops in and seals with a silicone seal. It fits very snug and has yet to leak on me! Also the mug is excellent at keeping my tea very hot for a really long time, in short I love my mug a lot!! Hope that this helps you out.

It's a soft spout, but the way it is constructed it is actually quite difficult for someone to bite through the silicone and enlarge the opening. The 2 slits where the water comes out are protected by a lip that extends over them. To give you an idea, my daughter goes through other brands of silicone spouts in a couple weeks, tops, by biting on the spout and enlarging the holes. I only have one Pura Kiki spout that we've used every night for a few months now and it shows no signs of tearing yet.

This doesn't seal well enough to be used as a sippy; it leaks. If you put a rubber ring under it (the same kind you would use for canning) it works fine.

The glass is of course PBA-free and the silicone sleeve is also. (So far, silicone is the safest of all the plastics). Now that I've bought 4 of these I am writing to the sellers to learn how we're supposed to clean under the sleeve? It opens just enough to allow water and bacteria to get underneath. This could be problematic down the road. I will also ask about the cap. This is a great question!

Nope...but you could probably get away with cutting a hole in the cuppow to modify it, but it's intended to be a sipper without a straw.

No you are not missing anything. This is a tray with a blue plastic Or silicon cover on top. The cover is supposed to seal up the tray after you put the cover on top and pour out excess water from the tray. It is "supposed" to seal the tray and the water will stay in place. However, like on my review said the cover really does not do the job. It will "partially" seal the tray and some corners or gaps will still form in between the tray and the cover. When I tilted the tray, some water will leak out. It does not really freeze in an angle. Now I have to be very careful when I freeze the water. I always put it flat so that it won't leak.

The lid/top screws off to expose a neat spring action spout to drizzle the oil. The spout does NOT screw off and is somehow a part of the bottle and cannot be removed for reuse.
