Independent Claim 1 — The Core Protection
In plain English, this patent protects a lid for a drinking vessel (tumbler) that has all of the following features:
-
Two-layer vacuum-insulated construction — The lid has a top portion and a bottom portion that together form a sealed, vacuum-insulated region (like the walls of a thermos, but in the lid itself).
-
An opening that passes through both layers without breaking the vacuum seal — There is a hole that goes through the top and bottom of the lid, but it is designed so that the vacuum-insulated region is never exposed to the outside air.
-
A removable, flexible insert that fits into that opening and:
- Conforms snugly to the opening shape
- Has a top lip that sits against the lid's top and a bottom lip against the lid's bottom
- Contains a semi spill-proof drinking opening
- Can be pulled out without exposing the vacuum-sealed region to the atmosphere
Key Dependent Claims (Added Features)
| Claim | Adds This Feature |
|---|---|
| 2 | The insert has a hollow body between its top and bottom lips |
| 3 | The drinking opening is near the hollow body |
| 4 | The lid's top has a raised rim |
| 5 | A tab helps remove the lid from the vessel |
| 6 | The lid's bottom also has a raised rim |
| 7 | The insert includes an air vent |
| 8 | The insert has a pull tab on the top or bottom lip |
| 9 | A body portion separates the top and bottom of the lid |
| 10 | The body portion includes a seal |
| 11 | The body portion includes a ring |
| 12 | The removal tab is on the ring |
| 13 | The seal is removable |
| 14 | The ring is removable |
| 15 | The air vent is near the drinking opening |
What This Means for Product Design
To infringe Claim 1, a product must have ALL three elements:
- A two-part vacuum-insulated lid
- An opening through both layers that doesn't break the vacuum
- A flexible, removable insert with a semi spill-proof opening
Design-around strategies:
- Use a single-wall (non-vacuum) lid — eliminates element 1
- Make the insert permanent/non-removable — eliminates "removable" from element 3
- Use a lid where removing the insert does expose the vacuum region — eliminates the sealing requirement
This is a relatively narrow patent focused specifically on vacuum-insulated tumbler lids with removable drink-through inserts — think products like YETI Rambler lids or similar insulated drinkware lid designs.
