Does anyone know what this lid is made out of? Silicone or plastic?

Why isn't the sippy cap made from silicone? Just ordered for grandson and am concerned now! It goes into the child's mouth!

The black ring in this picture is only part of the lid - I can't say for sure, but I believe it is silicone of some kind which forms a seal around the glass lid. I have never had a reason to use the lid. The server itself is only glass.

I would guess aluminum, the top of the lid is black, silver on the underside

Glass is BPA free. Even if the plastic lid is BPA free doesn't mean it's safe. They replace the BPA with another chemical. And I'm pretty sure it isn't safe either. this is what i found about siliconeIf plastic can't be avoided altogether, the safest type (meaning the most stable, slowest to degrade and leech chemicals into your water, food, etc.) is silicone.There is a lot of debate on silicone leaching chemicals. I did read some where that it's least likely in silicone that isn't heated up. As in the ones you cook with.So glass, 100% natural rubber and metal are the best I've read Glass is BPA free.

The plastic water-level window is plastic but I don't believe it's lined with a silicone seal. Also, there's a metal mesh strainer but it's lined by plastic as well (again, no silicone). OH and the lid's mostly plastic.

The lid is plastic. It's sturdy and fits tightly but fairly flexible and not difficult to pop off when you want/need to.

The inner seal seems to be the usual "rubber" seal. I don't know, because they do not say. I would guess that it is a man made material, just because real rubber is not used much any more. The seal does seem to be the usual seal that you would see in any lid with a seal.

You'll have to ask the manufacturer. I have no idea what the chemical composition of the plastic lid is.

It is made of both so do not make the mistake I made with my last one that had me buying a new one. Do not use lid in oven, the plastic will melt. I love my new one just as I loved my old one.

Not sure of the exact material but its light weight and very similar to your typical mason jar lid.

Plastic, I have had to replace mine because it started to leak. I have no trouble with it. I love mine and the replacement was cheep. I would recommend this crock to anyone

Not entirely sure but the Zojirushi website has lots of info. It's a hard plastic with what I think is gray silicone gasket. The lid disassembles for cleaning into 3 pieces. I can't say enough about this mug. If maintaining temperature over SEVERAL hours (although I've only used it for hot) is important to you, this thing is the bomb. And it's beautifully designed.

The lid is plastic with what appears to be a rubber type ring to seal the jar. Great product.

How does one know the difference? I can say that the red parts (flat lid, edges around the side) are plastic. But, the portion that "pops open", the opaque sides, are a flexible plastic. It could be silicone, but I don't know how to determine.

The lid is made with plastic the actual honey dispenser is glass works like stainless steel

It is hard plastic with a removable rubber ring around it like other travel mug lids. The rubber ring makes it fit snuggly and it removes easily for cleaning.
