The thermos cup is the "drinking water just need" of many friends, but if you accidentally choose the wrong one, the hot water will be annoying if the poisonous water comes out! Today, I have summarized three tips for you to buy a safe thermos cup to help you avoid the trap of "deadly thermos cup".
The first trick: check the material of the inner tank of the thermos cup
The material of the inner tank is the key to choosing a thermos cup.
Preference is given to thermos cups with SUS304 or SUS316 stainless steel stamps printed on the bottom.
SUS304 stainless steel is a food-grade safe material with good corrosion resistance and high temperature resistance, but it is not recommended to pack acidic or alkaline beverages. SUS316 stainless steel is a medical-grade safe material, with stronger corrosion resistance and high temperature resistance, and is suitable for acidic and alkaline beverages.
Remember to avoid 201 and 202 stainless steel liners, which are industrial-grade stainless steels and are less safe.
The second trick: check the outer packaging information of the thermos cup
When purchasing, it is necessary to carefully check the manufacturer information of the thermos cup and whether it is marked with food-grade implementation standards. The implementation standards can be queried on the enterprise information platform, and if the food implementation standards are not marked, it is recommended to avoid purchasing.
Tip 3: Smell and Evaluate**
The inner liner of the thermos cup with qualified quality should have no irritating odor. You can open it and smell it when you buy it, and if you have a pungent smell, you should avoid it. In addition, too low vacuum cups also need to be cautious, for example, 316 stainless steel raw materials ** are higher, so it is recommended to buy ** thermos cups above 50 yuan.
Precautions for the use of new thermos cups
Washing: Before using it for the first time, please use warm water and neutral detergent to clean the inside of the mug. Avoid using detergents with acidic or alkaline ingredients to avoid damaging the cup.
Preheat or pre-cool: In order to improve the heat preservation effect, it is recommended to preheat or pre-cool with hot or cold water before use.
Avoid turning it upside down: Make sure the sealing cap is tightly closed when using to prevent temperature loss. Avoid turning the thermos cup upside down to avoid temperature leakage.
Avoid storing acidic or alkaline liquids for long periods of time: Prolonged storage of such liquids may cause the coating on the inner wall of the thermos cup to peel off or deteriorate. Therefore, it is best to avoid storing acidic or alkaline liquids in a thermos cup for a long time.
By following the above three tips and precautions, you can easily avoid the trap of "deadly thermos cup" and enjoy a safe and healthy drinking experience.
