How Long Does It Take to Use a Vacuum Flask to Replace a New One?
From a healthy perspective, a stainless steel vacuum flask needs to be replaced with a new one after 6-8 months of use. Because many people’s living habits have not reached the habit of daily cleaning and daily high-temperature disinfection. Some lifestyles are very casual. Every time they drink water, there will be some left in the cup, which will not be found until the next time they drink. Microorganisms will grow in the water cup. Even if it is cleaned afterwards, if the inside of the water cup is not thoroughly cleaned and high-temperature disinfected in about half a year, it is no longer suitable for continued use.
From a functional point of view, various activities and careless actions in life can cause damage to the water cup. Once the outside of the water cup is deformed, it is likely to damage the structure of the water cup, reduce heat preservation, and even cause the weld to open. Although the part of the double-layer stainless steel sandwich is ultrasonically cleaned during the production process, it cannot reach the food safety level. Once the welding is opened, it will pollute the liquid in the cup. At the same time, when the water cup is not insulated, the effect of heat conduction will cause the outer cup layer is very hot, accidentally hurting yourself. The last is the use structure of the cup lid. If you use the cup with high frequency for a long time, the tightness of the cup lid will decrease after 6-8 months. Based on the above reasons, it is recommended to replace the water cup with a new one within 6-8 months of use. However, everyone should consider their own use environment and habits when replacing the water cup.
