After filling the bottle with hot or cold water, make sure to close the bottle tightly to prevent water leakage and burns. 3. Excessive use of hot or cold water may cause water leakage. Please refer to the water volume location diagram in the instruction manual. 4. Do not place it near a fire source to avoid deformation. 5. Please do not place it within reach of young children, and be careful not to let them play as there is a risk of burns. 6. Be careful not to burn yourself when placing hot drinks in the cup. 7. Do not include the following beverages: dry ice, carbonated drinks, salty liquids, milk, dairy drinks, etc. 8. When tea is kept warm for a long time, it may change color. It is recommended to use a tea bag or similar to brew it when going out. 9. Do not put the product in the dishwasher, dryer, or microwave. 10. Avoid bottle drops and large impacts to prevent surface dents that may cause poor insulation and other malfunctions. 11. If the product you purchased is only suitable for cold insulation, please do not add hot water for insulation to avoid burns. 12. If filled with salt containing foods and soups, please remove them within 12 hours and clean the thermos. 13. Prohibited from loading the following items: 1) Dry ice, carbonated beverages (to avoid the danger of rising internal pressure, which may cause the bottle stopper to fail to open or the contents to spray out). 2) Sour drinks such as Plum juice and lemon juice (can cause poor heat preservation). 3) Milk, dairy products, juice, etc. (may spoil if left for too long)
