No, the Thermos King Flask is not dishwasher safe. To maintain its insulation properties and finish, it should always be hand washed with warm, soapy water.
To maximize retention, pre-heat the flask with hot water (for hot drinks) or pre-chill with cold water (for cold drinks) for about 5-10 minutes before filling. Also, fill the flask completely, leaving minimal air space, and ensure the stopper is tightly sealed.
It is not recommended to put carbonated beverages in the flask. The pressure build-up can cause the stopper to eject forcibly and may damage the flask or cause spills.
This Thermos King Flask has a capacity of 470ml (approximately 16 fluid ounces), which is ideal for single servings of coffee, tea, or water.
Simply twist the stopper counter-clockwise a few turns to open the pouring channel, allowing you to pour your drink without fully removing the stopper. After pouring, twist clockwise to seal it tightly and prevent leaks.
Yes, the flask is suitable for hot soups and other liquid food items. Just ensure it is cleaned thoroughly with warm, soapy water and a bottle brush after each use, especially if used for food with strong odors or textures.
The Thermos King Flask comes with a 5-year guarantee, covering manufacturing defects under normal use. Please refer to Thermos' official warranty policy for full details on coverage and claims.
Ensure the stopper is securely tightened. For optimal temperature retention, pre-heat the flask with hot water (for hot drinks) or pre-chill with cold water (for cold drinks) for 5-10 minutes before adding your beverage. Fill the flask completely, leaving minimal air space.
Check that the twist-and-pour stopper is correctly assembled and fully tightened. Inspect the silicone seals on the stopper for any damage, wear, or misalignment. If seals are damaged, contact customer support for replacements if available.
Thoroughly clean the flask with warm soapy water and a bottle brush. For stubborn odors, fill the flask with a solution of white vinegar or baking soda (one teaspoon per cup of warm water), let it sit for several hours or overnight, then rinse thoroughly. Always ensure it's completely dry before storing with the stopper slightly open.
Proper setup and care will ensure your Thermos King Flask provides optimal performance and longevity.
