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.

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 silicone sleeve is very flexible. You just bend it till they pop out, or you could run it upside down under hot running water for a minute. It is the rage with mixologists because the cubes take so long to melt in drinks! We have several.

It goes along the rim of the mason jar, under the band, to seal it. That way it won't spill if you choose to drink out of the spout instead of the straw. Hope this makes sense!!

I believe there is an air space between inner and outer layers of the cup.probably allows for pressure changes and draining of trapped water should someone have disobeyed orders and put it in the dishwasher. I wouldn't give it too much thoight.

There is what I'd call a gasket inside the lid groove; don't know if it's silicone, but it does seal well - not just plastic on plastic.

There is a place on one side where you can screw in a water bottle. I've never tried it so I can't say how well it works.

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.

I believe it's for thermal expansion and contraction. If it didn't have the hole I'm the outer wall the air would expand when putting hot liquids in and possibly challenge the glass integrity. I have double walled Bodum glasses as well and they have a hole in the bottom too, but the Bodums have a rubber type plug over it for use in dishwasher.

Cheap curing causes silicone to come out of the membrane. No permanent fix, this works.

The metal spout is fixed to one side. You actually have to slip the metal part into a plastic component.

I used mighty putty to bond plastic to plastic and plastic to metal to stop the leak that the plumber left for me. It is still holding and no longer leaking. I never used it on fabric or silicone

Sorry not sure about that. Maybe soak silicone seal in dishwater for a bit?

There is a little slit in the silicone stopper. I have to squeeze it open before each time I put the cap on. There is a sweet spot between too tight and too loose when the lid screws on also. I think because air needs to flow between the silicone and the cap itself for the liquid to come through.

It does prevent air bubbles...by the way, I have tried every sippy cup. This is the only one I recommend. Hands down the best !

There's a silicone interface inside, but the container itself is made of glass and the cover is aluminum

It can be slipped off, but to be honest, I haven't had to do that yet. It is silicone and fits the bottle snugly. Not even a little condensation gets under the sleeve on my bottle. And the straw and mouth piece are easy to remove for cleaning as well.
