As an indispensable partner in our daily life, the thermos cup has brought us a lot of convenience. Today, I will tell you four important precautions for not using a thermos cup, so that you can use the thermos cup well and enjoy a healthy life.
First, don't pour in overheated liquids
First of all, it should be clear that the main function of the thermos cup is to keep warm, not heat. Therefore, please never pour excessively hot liquids directly into the thermos cup. The high-temperature liquid will cause damage to the sealing structure and insulation layer inside the thermos cup, and may even cause the thermos cup to deform or break. So, before pouring the liquid, wait a while for the liquid to come down to the right temperature before pouring it in.
Second, do not store acidic or alkaline liquids for a long time
The inner wall of the thermos cup is usually made of stainless steel, but prolonged storage of acidic or alkaline liquids can cause it to chemically react with the material, resulting in the production of harmful substances. Therefore, it is recommended to pour out the liquid in time after use and wash the thermos cup thoroughly to ensure the health and safety of the next use.
Third, do not leave the thermos cup in a sealed state for a long time
Thermos cups usually have excellent sealing performance, which can effectively prevent heat loss and liquid fluctuations. However, when leaving the thermos cup for a long time, try to avoid keeping it completely sealed. This is because sealing for a long time will cause air to be unable to circulate, and the temperature is too high or too low in the environment, which may increase the pressure in the thermos cup and even cause the danger of explosion. So, when the thermos is not in use, remember to open the lid a little to keep it ventilated.
Fourth, do not use a thermos cup to preserve perishable food
Many people will choose to use a thermos mug to preserve food, but not all food products are suitable for long-term storage in a thermos cup. In particular, perishable foods, such as milk and fruit juice, are prone to bacteria and spoilage because of their rich nutrients. So, if you want to preserve this type of food, choose a special crisper or refrigeration device.
To sum up, the thermos cup is a good helper in our lives, but we must pay attention to the following four precautions when using: do not pour in overheated liquid, do not store acidic or alkaline liquids for a long time, do not place the thermos cup in a sealed state for a long time, and do not use the thermos cup to preserve perishable food. Only by using the thermos cup correctly can it better play its role and bring us convenience and health.
