In vacuum thermoses, it is recommended that you do not close the lid immediately after pouring 95 degree hot water into the thermos and wait for about a minute. Hot water will expand the metal body and put pressure on the vacuum cover. The lids of vacuum thermoses filled with hot water must be opened slowly, especially when used with hot liquids, and the accumulated pressure must return to normal. These warnings must be taken into consideration as sudden pressure compression may cause explosions and burns. If steel thermoses are left in a humid environment for a long time, they may rust, like all stainless steel products. If the lid of the thermos is closed tightly when it is wet and it remains damp for a while, it is inevitable for rust to form. This is an error that occurs due to misuse. Wash the thermos made of stainless steel after use and let it dry without closing the lid. In this way, there will be no moisture left in the body. You can close the lid after drying. As long as the issues mentioned above are taken into consideration, you can use your thermos in a healthy way for years. It is in the product box.
