Precautions for stainless steel thermos cup

1. Use a small amount of boiling water (or ice water) to preheat or precool for 1 minute before use. The heat preservation and cold preservation effect will be better.
2. After putting hot or cold water into the bottle, be sure to close the bottle tightly to avoid burns caused by water leakage.
3. If you add too much hot or cold water, water leakage may occur. Please refer to the water volume location diagram in the manual.
4. Do not place it near a fire source to avoid deformation.
5. Please do not place it within the reach of young children. Be careful not to let children play as there is a risk of burns.
6. When putting hot drinks in the cup, please be careful of burns.
7. Do not put the following drinks: dry ice, carbonated drinks, salty liquids, milk, milk drinks, etc.
8. Hot tea will change color when kept warm for a long time. It is recommended to use tea bags for brewing when going out.
9. Please do not put the product in the dishwasher, dryer, or microwave oven.
10. Avoid bottles falling and huge impacts to avoid surface dents that may cause poor insulation and other failures.
11. If the product you purchased is only suitable for keeping cold, please do not add hot water to keep it warm to avoid burns.
12. If you put food and soup containing salt into it, please take it out within 12 hours and clean the thermos cup.
13. It is prohibited to load the following items:
(1) Dry ice and carbonated drinks (to avoid dangers such as internal pressure rising, causing the bottle stopper to fail to open or the contents to spray out).
(2) Acidic drinks such as plum juice and lemon juice (can cause poor heat preservation)
(3) Milk, dairy products, juice, etc. (will go rancid if left for too long)
