Silicone piece slipping off the lip? Try this

4 month update: My fix was still going strong when someone at work decided that I didn't need the thermos anymore and gladly swiped it from me. I guess they saw how much I liked it and decided it was easier to steal than buy one themselves. So here I am back to buy another one. Going to use the same O-ring fix I described before on this one to keep the silicone piece in place. Seriously, try it if you are having that problem. It works good. Original Review/fix So when I bought this thermos, I read a lot of reviews that people were having problems with the lid. Where the silicone piece would get loose and the lid would fail to open when you push the button. I read that a lot of people were buying new lids from the manufacturer because the silicone piece was not able to be purchased by itself. Well I'm not sure if the silicone piece just ended up getting loose over time, but the problem with mine was shortly after I bought it, that silicone piece started slipping off the lip that is on the cap. So I was trying to figure a way to keep that from happening, and this is what I came up with. Go to Lowe's and buy the delta o-ring set for repairing a faucet. I included a picture with the model number. It has four o rings, they are the same diameter but 2 are thicker. Well I took off the white silicone piece that seals the lid, and I put the two thicker O-rings over the circular area and pushed them down so that the silicone piece that opens the lid cannot slip over the lip. Then I put one of the smaller O-rings at the top of the other two to keep them from moving up. Pictures are included to kind of show you what I did. I've been using it about a week and so far so good. Now if that silicone piece that opens the lid gets too loose then I imagine it will eventually stop opening the lid but my solution fixes it from slipping over the lip. Hope this helps somebody else out there.
