1. If the thermos cup is dented, you can use hot water to scald it slightly. Because of the principle of thermal expansion and contraction, the thermos cup will recover slightly.
2. If it is more serious, use glass glue and a suction cup. Apply the glass glue to the recessed position of the thermos cup, then align the suction cup with the recessed position and press it tightly. Wait until it is completely dry and pull it out with force.
3. Use the viscosity of the glass glue and the suction of the suction cup to pull out the dented position of the thermos cup. If these two methods cannot restore the thermos cup, then the dented position of the thermos cup cannot be restored.
4. The dent in the thermos cup cannot be repaired from the inside because the internal structure of the thermos cup is very complex. Repairing it from the inside may affect the insulation effect of the thermos cup, so try to repair it from the outside.
5. If used normally, the life of the thermos cup is relatively long, and it can be used for about three to five years. However, you must pay attention to the protection of the thermos cup, so as to extend the life of the thermos cup.
