Generally speaking, it is recommended to replace the sealing ring of the insulated cup every 6-12 months to ensure better insulation and leak prevention effects. However, the specific replacement cycle still needs to be determined based on actual usage:
The situation where the sealing ring needs to be replaced
Aging, deformation, or damage of the sealing ring: If cracks or deformation are found on the surface of the sealing ring, or if the material becomes hard or brittle, it indicates that the sealing ring has aged and needs to be replaced in a timely manner.
The insulation effect significantly decreases: When the insulation effect of the insulated cup is not as good as before, such as when hot water quickly cools down, it is likely that there is a problem with the sealing ring, which leads to accelerated heat loss.
Leakage or poor sealing: If there is still water leakage in the insulated cup after the cup lid is tightened, or if the cup lid cannot fit tightly with the cup body, it may indicate that the sealing ring is no longer working properly.
The situation where the replacement cycle can be appropriately extended
Low frequency of use: If the insulated cup is not used frequently, such as only occasionally, the wear of the sealing ring is relatively small, and its service life may be longer.
Good usage habits: If the thermos can be cleaned promptly after each use to avoid prolonged contact of the sealing ring with acidic, alkaline substances or dirt in the beverage, and the thermos can be stored properly to avoid impact or prolonged exposure to high temperatures, the service life of the sealing ring may also be extended.
