Recently, news about the "deadly thermos cup" on the Internet has appeared frequently, I don't know if you have noticed this phenomenon.
The occurrence of these accidents makes people have to conduct a safety inspection on the thermos cup used daily. If you are also worried about the potential safety hazards of your thermos cup and want to avoid the situation of "hot water in, poisonous water out", then follow me to learn how to choose a safe thermos cup!
When buying a thermos mug, the most important step is to check the material of the inner tank. When you see a thermos mug with "SUS304" or "SUS316" stamped on the bottom of the inner tank, you can choose with confidence.
sus304: This is a food-grade stainless steel, which has very good corrosion resistance and high temperature resistance, and is suitable for loading most beverages, but it is not recommended to hold acid-alkaline beverages.
sus316: This material belongs to medical grade stainless steel, which has stronger acid and alkali resistance than 304 and has a wider range of applications.
Key points: Be sure to avoid using "201" and "202" stainless steel as the inner tank of thermos cups, both of which are industrial-grade stainless steel and extremely unsafe for health.
Another important step when making a purchase is to check the outer packaging of the thermos mug. Focus on the following two points:
Manufacturer information: Certified manufacturer information is an important symbol of quality assurance.
Food-grade implementation standardsEnsure that the product is marked with food-grade implementation standards and can be queried on the relevant enterprise information platform. If it is not clearly labeled, it is recommended not to buy it.
A high-quality thermos cup liner usually does not have a pungent odor. When buying, you may wish to open the lid and smell it, if there is an obvious pungent odor, it is likely that there is a problem with the material or process, and it is not recommended to choose.
In addition, it is also a factor that cannot be ignored. The thermos cups that are too cheap on the market often compromise on the material and process, so don't ignore the safety of the product while pursuing cost performance.
