Thermos Alta Slide Lock Lid Disassembly

This video describes how to disassemble the slide lock lid on a Thermos Alta Stainless Steel Tumbler / Mug.
I came into possession of this Thermos Alta Stainless Steel Tumbler which had been abandoned in the waiting area of an auto service center. It was a good quality mug, but looked like it had never been cleaned. Super gross. When I tried to disassemble it for cleaning, I couldn't figure out how to remove the slide from the rest of the lid. Searching the internet yielded no results, so after whacking it with a mallet to remove it, and seeing how it was retained, I figured I'd make a video in case others want to disassemble the slide from their lid. Happy cleaning!

The new versions can be opened way easier. Pull on the part under the lid (that has locks shapes on it) then (while pulling) slide the top slider (open close thing) past the regular open position. It should pop up and release. They removed the locking wedge tabs that are in the video. The slider is held on with the hidden plastic piece that is holding the big spring.

I was dreading trying to figure out how to pop open my lids before reading your comment. Thank you so much, so easy!!

Thanks for this!

Thanks so much. This lid was driving me crazy. I was really hoping for a deep clean on one of these. The older design is much easier to take apart. For me, this seems like too much effort. I'll just hope the dishwasher is enough for the lid. The video was great at explaining how everything works.

A much easier way to do this is to simply place your lid in the open position. Take a butterknife and apply pressure upward to the mouthpiece opening, and it will pop right up.

Thanks for the confirmation. A paint can opener worked really well also.

broke a butter knife trying to do this. argh!

Just what I was looking for 👍👍

Thanks man. Really helpful video

[@mattwaelder]

alright, so I finally got it to work. i guess mine was an older model so it didnt have the nifty thing where you pull on the locking mechanism on the underside of the lid to release the slide... mine was like the one in this video. simplest thing to do is pop the slide open, stick a sturdy butter knife under the slide and lever it up. this will deform the plastic tabs and the slide will pop off. Despite the damage i was able to clean the lid and put it back together just fine. what a shit design, no wonder they changed it lmao

The video took a long time but did not show how it was disassembled.

Tell people you're stupid without telling people you're stupid

[@nicarob4257]

..just slide open the tab, put a screwdriver between tab and lid, and pop open .
It’s really simple.

[@maxbin816]

Your method is very good, thank you. If such a cup lid is not opened and cleaned frequently, it will be a health killer.

Indeed !
..most people don’t realize what nasty bacteria lurks within their lid 🤢🤯

It's okay video but if you can shorten it up a lot there's way too much of it you're just talking and we don't need it when you're trying to do something quickly people don't have 10 minutes to learn how to open a lid that takes 2 minutes to learn

I was watching the video on two times faster so the video was 5 minutes long still 3 minutes too long
