With the improvement of living standards, as of the end of March 2024, the number of motor vehicles in China has reached 402 million. It can be said that cars have become an important means of transportation for people's daily lives. During the journey of driving, the travel time varies, and how to ensure sufficient drinking water has become a problem. Many people prefer to put a few bottles of bottled water in their cars for convenience, but there are actually many drawbacks to this practice: the temperature in the southern summer can reach 40 ℃+, the temperature in a closed car space can reach 70 ℃, and in some areas with direct sunlight, the temperature can even reach 90 ℃. High temperature can accelerate the hydrolysis of bottled water to produce bisphenol A, and there is also a risk of fire.

A good way to ensure sufficient drinking water during the trip is to bring your own water cup. This not only meets the drinking water requirements, but also is healthy and environmentally friendly. So, how to choose a suitable car water cup?
1. Capacity of car water cup: The capacity is generally selected as 400~800ml, which can basically meet the drinking water requirements during the journey and is convenient to place in the car.
2. Opaque appearance of car water bottles: When using water bottles in cars, try to choose opaque styles because transparent water bottles act as a convex lens when filled with water, which can focus energy under direct sunlight and may cause fires inside the car. Especially, some drivers like to place water bottles in cup holders or under the front windshield, which are easily exposed to sunlight. Using opaque water bottles can to some extent avoid the risk of fire.
3. The car water bottle has a lid to prevent dust from entering: Try to choose a water bottle with a lid to avoid dust and other things from entering the water bottle and affecting the water quality.
4. Car water bottles are easy to use and can be opened and closed with one hand: Due to limited space in the car, water bottles that are easy to use and can be operated with one hand are preferred.
5. Type of car cup: Straight cup is better, with a cup body diameter not exceeding the cup holder to avoid being unable to fit into the cup holder. Generally, the diameter of the cup holder is 7-8cm, and the cup body diameter should not exceed this size. You can measure the cup holder size of your car specifically. For some irregular cup bodies, such as small top and large bottom, irregular cup bodies may not fit into the cup holder. The upper part is large and the lower part is small, which is difficult to fix and may shake.
6. Material shock resistance of car water cup: During driving, there will always be bumps and shakes in the car. The water cup should be made of impact resistant material to avoid breakage, scratches or burns to oneself and passengers.
7. Material safety of car water bottles: Regardless of whether it is a car water bottle or not, attention should be paid to the safety of the water bottle material. Water bottles should not produce harmful substances to health and should not harbor dirt and grime.

TRITAN material water cups do not hydrolyze to produce bisphenol A, are impact resistant, and are very suitable for car use. 316 stainless steel insulated cups are corrosion-resistant and are suitable for use in medical devices as well as car water bottles.
