Common sense of using insulation cups
The State Administration for Market Regulation also mentioned some common sense about the use of insulated cups in the consumption tips of insulated cups. In addition to the "carbonated drinks, soybean milk, milk" that cannot be filled, there are three points. Please note:
Before using a new insulation cup, it is recommended to rinse it with water to remove any dust or dirt that may remain on the surface.
When filling the bottle with boiling water, do not overfill it. It is recommended to be at least 2 centimeters below the bottle mouth to prevent scalding caused by the overflow of boiling water when opening the lid; Do not vigorously shake the insulated cup with the lid closed to prevent pressure buildup inside the cup and injury from the ejected lid or sprayed hot water when opening the lid.
Children should be watched by their parents when using insulated cups. Do not put hot water that is too hot to avoid the risk of burns.
Finally, when purchasing insulation cups, everyone should purchase through legitimate channels and try to choose products from well-known brands. At the same time, attention should also be paid to checking the completeness of instructions, labels, and product certificates to avoid purchasing "three no products".
