Redesigned the top according to your specs. I separated the cutout from where you drink from the area where you control the cover: I consider being more hygienic this way. The sliding piece is easy to assembly and its shape prevents from falling inside the tumbler. I hope that the image is suggestive enough. I attached the STEP file wich is standard for 3D model and can be opened in most modelling programs. I can provide detailed dimensional drawings and STL files for 3D printing as well. The ratio between reservoir volume and heating liquid chamber volume can be easily adjusted once you know what your needs are. If there's anything else that I missed please tell.

This is my concept with vacuum chamber.
Assembly goes like this:
1. Bottom plate is glued to the bottom of the vacuum chamber.
2. You put inside the previously assembled trigger mechanism (trigger disk, spring and support). The support has the following advantages:
- eliminates the protruding elements from the bottom of the
liquid chamber (difficult to manufacture)
- holds the spring and the trigger disk
- centers the trigger disk at assembly point.
3. Mount the ring on the liquid chamber
4. Mount the above assembly inside the vacuum chamber
Notes: bottom plate and ring should be glued to assure sealing for the hot liquid chamber.
5. External coat is added - you can use different materials, markings, logo and then just switch them
6. Top (lid) has two additional elements that can be easily assembled: silicon seal and sliding cover.
If there are any questions please don't hesitate to ask.

Designed in CATIA and exported as STEP and STL for convenience. Obviously, if you need the source Catia files I can provide that. Check the PDF drawing for details about composition and manufacturing.
