The "Thermos" of thermos is synonymous with "thermos" in the English dictionary, and the history of thermos cups/bottles can be said to be the history of thermos. The historic thermos who flew into the skies with the Wright brothers and transported plasma as a munition on the battlefields of World War II.
 
The figure-of-eight buckle is the symbol of the one-button opening cup of the thermos, and when opening the lid, you need to untie the figure-eight button down before pressing the elastic button to press the button of the pop-up, which is a little awkward to operate with one hand. THERMOS has also tried a new way to open the lid of the pop-up cup, for example, the JNS series has designed the opening button on the top of the thermos cup, which is even more uncomfortable to use, and the pop-up cup lid will touch the hand after pressing the opening button.
 
There are many thermos series, only by the first three letters of the series name can be distinguished, for example, JNL500, 501, 502 series of thermos cups themselves are not different, the difference lies in the surface of the cup paint and the place of origin.
 
The JNL series is an upgraded version of the JMY series, and the 500ml model is priced at about 300 yuan, weighing only 200g, which is 130g lighter than JMY. The drinking spout on the lid of the cup is slightly larger than JMY's, and the water comes out more smoothly.
 
Compared with Tiger and Zojirushi, the thermos has fewer cap cup series, the appearance design is simple and generous, the JNO series equipped with a 160° semi-rotating open lid is more labor-saving to use, and the attached anti-scald PP drinking cup mouth is removable, and the price of the Chinese JNO series is about 300 yuan.
 
THERMOS has factories in Malaysia, the Philippines and Jiangsu, and the products produced in the three places on the domestic official e-commerce are available, JNL502 is made in Malaysia, JNL501 is made in China, the products are not much different, and consumers with origin needs can pay attention to the details of the product when buying. The series that are currently not available in China such as JNR are not special compared to other products, and are not recommended.
 
Relatively speaking, the selectivity of thermos in children's thermos cups is not as good as that of Tiger and Zojirushi, only straw pop-up cups, which are convenient for direct drinking, but the thermal insulation performance is not as good as that of adult thermos cups. The highest-priced FEC-280 cup has handles on both sides, which is similar to Tiger's toddler thermos cup, and the price of 355 yuan is also the same level as Tiger. FEQ-400 and F4001 capacity is not large, both do not exceed 400mL, suitable for younger children, unlike Tiger Zojirushi and other 600mL children's thermos cups, FEQ-400 also comes with a strap, which is more convenient to carry, and the price is 285 yuan.
