Why can’t a thermos cup be left in the car when parked for a long time in summer?

When parking for a long time in hot summer, try not to leave the thermos cup in the car, especially if it is directly exposed to the sun. High temperature environment will have an impact on the material and sealing performance of the thermos cup, which may cause the following problems:

1. Temperature is too high: In a hot car, the temperature inside the thermos cup will rise rapidly, which may further heat up the originally hot beverage and even reach an unsafe temperature. This may result in a risk of burns, especially for children and pets.

2. Leakage: High temperature will cause the pressure in the thermos cup to increase. If the sealing performance is insufficient, it may cause the thermos cup to leak, causing dirt or damage to other items in the car.

3. Material deterioration: High temperature will affect the materials of the thermos cup, especially plastic or rubber parts, which may cause the material to deform, age, and even release harmful substances.

In order to avoid the above problems, it is recommended to take the thermos cup out of the car when parking for a long time in hot summer, preferably in a cool and ventilated place. If you need to maintain the temperature of your beverage for a long time, you can consider using a professional car cooler or hot and cold box instead of a thermos cup to ensure that your beverage is kept within a safe temperature range. At the same time, choose a high-quality thermos cup to ensure it has good sealing performance and high temperature resistance to ensure safety and convenience of use.
