The new thermos cup is not used, and it needs to be boiled once when it is used for the first time, which can play the role of disinfection and sterilization. This is because there may be some dust and some bacteria in the new thermos, so it is ok to start scalding or soaking for a while.

The new thermos cup is soaked in boiling water for the first time, which can not only test the sealing and heat preservation of the thermos cup, but also remove the smell of some aprons on the lid, so it should be scalded with boiling water.

What should I pay attention to when using a thermos for the first time?

1, which needs cleaning before use.

When the thermos cup is used for the first time, it must be cleaned inside and outside, preferably scalded with boiling water or neutral detergent, and disinfected and cleaned.

2. Avoid collision with hard objects

Although compared with other cups, the thermos cup is not easy to be broken, it will be easily damaged or deformed when it collides with some hard objects, thus affecting the firmness of the welded part, ultimately destroying the insulation effect and greatly reducing the service life of the thermos cup.

How long is it normal to keep the thermos cup warm?

The holding time of different materials will be different. Generally, a better thermos cup can keep warm for about 12 hours, and a less one can only keep warm for 3-4 hours, but most thermos cups can keep warm for more than 6 hours.

In the process of using the thermos cup, be careful to tighten the plug properly, and don't rotate it too hard to avoid the failure of the turnbuckle, otherwise it will also affect the insulation effect.
