Operating Instructions
- Filling the Mug:
- Unscrew the lid.
- Fill the mug with your desired beverage. Do not overfill; leave a small space below the rim to prevent spills when closing the lid.
- For hot beverages, ensure the liquid is not boiling to prevent pressure buildup.
- Securing the Lid:
- Screw the lid back onto the mug tightly to ensure a leak-proof seal.
- Engage the lock mechanism on the lid (if present) to prevent accidental opening.
- Drinking:
- To open, slide the lock mechanism (if engaged) and press the button to flip open the lid.
- Drink directly from the spout.
- After drinking, close the lid firmly until it clicks, and re-engage the lock for secure transport.

Important Safety Note: When using with hot beverages, exercise caution to prevent burns. The mug's exterior may remain cool, but the contents will be hot. Always test the temperature of the beverage before drinking, especially when serving children.
Maintenance
Proper cleaning and maintenance will ensure the longevity and hygiene of your THERMOS mug.
- Hand Wash Only: The mug and its components are designed for hand washing. Do not wash in a dishwasher, as this may damage the vacuum insulation and exterior finish.
- Daily Cleaning: After each use, disassemble the lid components (if possible) and wash all parts with warm water and mild dish soap. Use a soft brush for hard-to-reach areas.
- Rinsing and Drying: Rinse all parts thoroughly with clean water. Allow all components to air dry completely before reassembling or storing to prevent mold or odors.
- Deep Cleaning: For stubborn stains or odors, a mixture of baking soda and water can be used. Let it sit for a few hours, then rinse thoroughly.
- Avoid Abrasives: Do not use abrasive cleaners, scrubbers, or bleach, as these can damage the stainless steel finish and seals.

Troubleshooting
If you encounter issues with your THERMOS mug, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor Temperature Retention | Lid not sealed properly; mug not pre-heated/cooled; extreme external temperatures. | Ensure lid is tightly screwed on. For best results, pre-heat with hot water or pre-cool with cold water for 5-10 minutes before filling. |
| Leaking | Lid not secured; seal gasket missing or improperly seated; lid components damaged. | Check that the lid is screwed on tightly and the flip top is fully closed and locked. Verify all silicone gaskets are in place and correctly seated. Inspect lid for cracks or damage. |
| Difficulty Opening/Closing Lid | Food/beverage residue; damaged mechanism. | Clean the lid thoroughly, paying attention to the flip mechanism and threads. If damage is visible, contact customer support. |
| Unpleasant Odor | Incomplete drying; residue from previous beverages. | Ensure all parts are thoroughly cleaned and completely air-dried after each use. Use a baking soda solution for deep cleaning. |
