Thermal insulation pot is a common daily necessity, widely used in life. It can keep your drink hot or cold for hours. In the summer, you can use a thermos to bring iced coffee to the basketball court.
In winter, you can bring hot tea to the library in a thermos. Heat preservation pot is closely related to people's work and life. It is used to store chemicals in the laboratory and drinks at the picnic.
There are many types of thermos with shells made of bamboo, plastic, or metal. The mouth of the flask has a rubber ring, which is used to hold the glass inside. The bottleneck is the worst place for insulation, so make it as short as possible.
The origin of thermos pots can be traced back to the 17th century when European physicists created the earliest thermos pots. In 1902, a German archaeologist named Berg applied for a patent for the thermos. Thermos pots were first used in laboratories, hospitals, and expeditions. It is now widely used by people.
How can you make your thermos last longer?
1. High-temperature disinfection. When you buy a new thermos, you should first rinse it with boiling water or detergent several times. This will kill the bacteria so that you can use your thermos safely.
2. Keep dry. Every time you use the kettle, you should keep the inside of it dry. To prevent odors or stains, you should wash it each time with detergent and then dry it.
3. Avoid collisions. As we all know, some thermos is made of fragile materials. Crashes can make it crack or break. A broken thermos won't hold heat or will leak, and it won't work.
4. Wash with white vinegar. If you have an old thermal pot, after long use, it has a lot of tea stains inside that are difficult to clean. We can soak it in diluted white vinegar for half an hour so you can clean your thermos.
When using a thermos, we should also pay attention to:
1. Avoid burns. If you want to put hot water in your thermos, don't overfill it. The full boiling water may overflow. The heat preservation kettle is vacuumed, and the heat preservation time is long. Be careful of burns when drinking hot drinks. It's best to pour it into a glass and then drink it at the right temperature.
2. Avoid loading gas that is easy to produce pressure. Don't fill your thermos with dry ice or fizzy drinks, they can spill everywhere. Don't add solid acids or alkalis, which will eat away at your pot.
3. Avoid distortion. Do not heat the thermos directly. Don't put the kettle in a hot place.
4. Avoid hot milk. To minimize bacteria, it's best not to store hot milk or baby food in a thermos.
5. Avoid burns. Children can accidentally knock over the thermos. The thermos should not be placed where children can reach it.
