Why can’t insulated bottles be left in the car during long summer parking?

As the temperature continue to rise, hot summer weather is becoming more and more common. Many people choose to use insulated bottles to keep their drinks warm during the hot summer weather. However, insulated bottles should not be left in the car when parked for long periods of time due to the fact that the temperature inside the car can rise very easily, especially when parked, where the temperature may quickly rise to over 50°C. This high-temperature environment may lead to deformation, embrittlement and release of harmful substances from the thermos, which may be hazardous to human health.

First of all, the high temperature inside the car may damage the sealing performance of the insulated bottles. The sealing performance of insulated bottles is one of the key factors in maintaining the temperature of beverages. If the sealing performance is damaged, heat will escape, resulting in a drop in the temperature of beverages. In a high temperature environment, the sealing ring and plastic parts of the insulated bottle will be easily deformed, which will lead to a decrease in the sealing performance and affect the heat preservation effect. At the same time, high temperature may cause the pressure inside the bottle to increase, and if the sealing performance is insufficient, it may cause the bottle to leak, dirty the car, or damage other items.

Second, the high temperature environment in the car may also damage the material of the insulated bottle. The materials used in insulated bottles are usually plastic or stainless steel, which are prone to deformation, brittleness, or release of harmful substances in high-temperature environments. Plastic materials, in particular, are easily deteriorated by prolonged exposure to high temperatures, releasing harmful substances that are hazardous to human health.

Finally, as the high temperature and humid environment in summer easily breed bacteria and mold, if the bottles are left in the car for a long time, it will increase the reproduction of bacteria and mold in the drinks, which will bring risks to human health. When people drink these contaminated beverages, it can be hazardous to their health.

Therefore, when parking for a long time, in order to avoid high temperature inside the car, people can choose to park in the shade or use a sunshade when parking, and at the same time, they can start the air-conditioning inside the car to reduce the temperature inside the car. In addition, in order to ensure the hygiene and health of beverages, it is recommended to wash the bottles often and avoid storing beverages for a long time. Of course, it is best not to put the insulated bottles in the car.

In summary, the hot weather in summer puts higher requirements on the use of insulated bottles. In order to ensure the safety and hygiene of our drinks, we should use insulated bottles correctly, avoid putting them in the car, and pay attention to keeping the environment in the car dry and clean to reduce the reproduction of bacteria and mold. Only in this way can we ensure our health and comfort in the hot summer weather.
