Precautions for using a thermos flask

1. Do not use in a microwave oven.

2. This thermos flask is a high-vacuum insulated product with a long heat retention time. When drinking hot beverages, take precautions to avoid burns. It is recommended to pour the beverage into another container and allow it to cool to a suitable temperature before drinking.

3. Do not fill this high-vacuum insulated product with dry ice, carbonated beverages, or other liquids that may generate high pressure. Do not add strong acids or alkalis, as this may corrode the inner wall of the container.

4. To minimize bacterial growth, do not store hot milk or baby food in the thermos flask.

5. Avoid any form of direct heating or placing it in high-temperature environments to prevent product deformation and affect its use.

6. Avoid dropping, bumping, or subjecting the product to strong impacts, as this may deform the product and affect its effectiveness.
