FAQs
Is the Thermos Stainless King Flask dishwasher safe?
No, it is recommended to hand wash the flask with warm, soapy water to preserve its vacuum insulation and external finish.
How long will it keep drinks hot or cold?
Thanks to Thermos vacuum insulation technology, it is designed to keep drinks piping hot or refreshingly cold for hours. Exact retention times can vary based on external temperature and how often the flask is opened.
Can I put carbonated drinks in this flask?
It is not recommended to use carbonated beverages in the flask, as pressure build-up can cause the stopper to eject forcefully or damage the flask.
What is the capacity of this flask?
This Thermos Stainless King Flask has a capacity of 470ml.
How do I clean the stopper mechanism?
The stopper can be disassembled for thorough cleaning. Carefully twist apart its components, wash them with warm, soapy water, and use a small brush for hard-to-reach areas. Ensure all parts are dry before reassembling.
Does it come with a warranty?
Info needed: Please refer to the product packaging or manufacturer's website for specific warranty information.
Will it fit in a standard car cup holder?
Info needed: The fit into a standard car cup holder depends on the diameter of the flask and the specific cup holder size. Please check the product dimensions if this is a critical requirement.
Troubleshooting
Drink doesn't stay hot/cold as expected.
Ensure the stopper is tightly sealed after filling. Pre-conditioning the flask (pre-heating with hot water for hot drinks or pre-chilling with cold water/ice for cold drinks) for 5-10 minutes before adding your beverage can significantly improve temperature retention.
Flask is leaking.
Check that the stopper is properly assembled and screwed on tightly. Inspect the silicone seals and gaskets on the stopper for any damage or misalignment. A damaged seal may need replacement.
Metallic taste in beverages.
Wash the flask thoroughly with warm, soapy water and rinse multiple times. For persistent taste, soak the interior with a mixture of warm water and a tablespoon of baking soda for a few hours or overnight, then rinse thoroughly.
Difficulty pouring with the twist-and-pour stopper.
Ensure the stopper is properly unscrewed a few turns (as per its design) to create an opening for pouring. If it feels stiff, clean the stopper mechanism to remove any build-up that might be hindering its movement.
Exterior of the flask is hot/cold to the touch.
This indicates a potential compromise in the vacuum insulation. While rare for Thermos products, if the flask exterior is mirroring the temperature of the contents, contact customer support for further assistance or warranty information.

Setup, Compatibility & Care
Initial Setup
- Wash Before First Use: Before using your Thermos Stainless King Flask for the first time, thoroughly wash all components (flask body, stopper, and serving cup) with warm, soapy water. Rinse well and allow to air dry completely.
- Pre-Conditioning (Optional but Recommended): For maximum temperature retention, pre-heat the flask with hot water for 5-10 minutes before adding hot beverages, or pre-chill with cold water/ice for 5-10 minutes before adding cold beverages. Empty the water before adding your drink.
Compatibility
- The Thermos Stainless King Flask is designed for both hot and cold beverages. This includes coffee, tea, soup, water, juices, and more.
- Avoid carbonated beverages: The build-up of pressure from carbonation can damage the flask or cause the stopper to eject forcefully, creating a safety hazard.
- Do not use for dairy products or baby food: These can spoil and develop bacteria, which is difficult to clean thoroughly from the flask's interior.
Care & Maintenance
- Hand Wash Only: To preserve the vacuum insulation and finish, always hand wash your flask. Do not put it in a dishwasher.
- Gentle Cleaning: Use a soft sponge or bottle brush with warm, soapy water. For stubborn stains or odors, a mixture of baking soda and warm water can be used for soaking.
- Thorough Rinsing: Rinse all components thoroughly to remove any soap residue.
- Air Dry: Allow all parts to air dry completely before reassembling and storing to prevent mildew or odors.
- Stopper Care: Periodically disassemble the stopper (if possible, referring to any product-specific instructions) and clean all parts to ensure proper hygiene and seal integrity.
- Avoid Abrasives: Do not use abrasive cleaners, scouring pads, or bleach, as these can damage the stainless steel finish and internal lining.
