Why shouldn't a thermos be left in a car during extended periods of parking in the summer?

During hot summer days, it's advisable not to leave a thermos in the car, especially when exposed to direct sunlight. High temperatures can have an impact on the materials and sealing performance of the thermos, potentially leading to the following issues:

Excessive Heat: Inside a hot car, the temperature within the thermos can quickly rise, further warming up already hot beverages, and even reaching unsafe temperatures. This could pose a risk of burns, particularly dangerous for children and pets.

Leakage: High temperatures can cause an increase in pressure inside the thermos. If the sealing performance is compromised, this might result in leaks, potentially soiling the interior of the car or damaging other items.

Material Degradation: Elevated temperatures can affect the thermos' materials, especially plastic or rubber components, leading to deformation, aging, and potentially releasing harmful substances.

To avoid these issues, it's recommended that during hot summer days with extended periods of parking, the thermos should be taken out of the car and ideally placed in a cool and ventilated area. If you need to maintain beverage temperature for an extended period, consider using a specialized in-car cooler or thermoelectric box instead of the thermos to ensure beverages stay within a safe temperature range. Also, choose a high-quality thermos with reliable sealing capabilities and high-temperature resistance to ensure safety and convenience during use.
