When it comes to thermos cups, let's first talk about the principle of thermos cups. The stainless steel vacuum flask uses a getter to remove the air in the middle of the two layers through a high temperature pressure in a vacuum furnace at 600 °C. If it is not completely emptied, the remaining air will be absorbed by the getter, and finally the complete vacuuming process is completed. This getter is manually welded to the inside of the cup.
1. Store properly and avoid falling from heights
When we do not use the thermos for a long time, we should put the thermos in a place that is not easily touched. Many times our thermos cup falls, although we find that the appearance of the cup has no effect, thinking that it can be used after cleaning. But in fact, sometimes it may cause the internal getter to fall off, causing the cup to leak vacuum.
2. Store dry to avoid mildew
When we do not use the thermos for a long time, drying the thermos is the most basic step in the storage of the thermos. The detachable parts in the thermos should be disassembled one by one and cleaned separately. After cleaning, wait for them to dry before assembling them for storage. Friends with conditions, if we want to store the thermos for a long time, we can also put some bamboo charcoal bags or food desiccant in the bottle, which can not only absorb moisture but also remove the odor caused by long-term storage.
3. Accessories cannot be stored separately
Some friends must have encountered this situation. The water cup is cleaned and dried, and then not assembled, and the accessories are stored separately. After taking it out for a while, it is found that the silicone sealing ring of the cup will turn yellow or sticky. This is due to the aging of the silicone sealing strip in contact with the air for a long time. Therefore, the cups that will not be used for a long time must be cleaned, dried, assembled and stored.
