After the stainless steel inner liner is dented, it is recommended that the use of insulated cups be closely related to the degree of indentation and material. If the depression is severe, it is not recommended to continue using it to avoid affecting safety and insulation effect.
1. Reasons for the formation of concave inner liner
Common materials for the inner lining of thermos cups include stainless steel, ceramics, glass, etc. Among them, stainless steel inner liner has become the main material for insulated cups due to its superior insulation performance.
However, using a thermos cup inevitably leads to collisions, falls, and even dents in the inner container during normal use. The main reasons for the concave stainless steel inner liner may be problems during the manufacturing process, or factors such as long-term use and external impact.
2. The impact of concave inner liner on insulated cups
When the stainless steel inner liner of the thermos cup is dented, it not only affects the insulation performance, but may also lead to problems such as insufficient sealing, water leakage, and secondary pollution of the thermos cup. If the depression is large, it may also damage the structure of the insulated cup and affect the safety of use.
3. How to deal with the concave inner liner
When a depression is found in the stainless steel inner liner of a thermos cup, the first thing to consider is the degree of the depression. If the depression is severe, it is recommended to stop using it to avoid causing safety hazards to oneself.
If the indentation is light, the thermos can still be used, but it needs to be regularly inspected, cleaned, and disinfected to avoid contamination. In addition, for slight dents, they can be slightly adjusted and repaired to restore their flatness.
4. Preventive measures for concave inner liner
To avoid dents in the inner lining of the thermos cup, preventive measures can be taken from the following aspects:
(1) Choose high-quality insulated cups, and try to purchase insulated cups with brand guarantee and qualified craftsmanship.
(2) During normal use, it is important to avoid situations such as dropping or colliding, and not to place the thermos cup at a high or easily bumped location.
(3) Regularly clean, disinfect, and inspect to avoid contamination.
5. Conclusion
The concave of the stainless steel inner liner has a certain impact on the use of the insulated cup, and it needs to be judged according to the specific situation. If the depression is severe, it is recommended to stop using it to avoid safety hazards. Preventing inner pot depression can be achieved through proper use and maintenance, as well as selecting higher quality and more reliable insulated cups to improve their service life.
