The thermos cup is developed from the thermos bottle. The principle of insulation is the same as that of the thermos bottle, but people make the bottle into a cup for convenience. There are three ways of heat transmission: radiation, convection, and transfer. The silver cup in the thermos cup can reflect the radiation of hot water, the vacuum of the cup and the cup body can block the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection. The thermos bottle also applies the principle of magnetized water, which is to add magnets to the bottom and cap of the bottle to magnetize the water.
The interior and exterior are made of stainless steel, refined with advanced vacuuming technology, with an elegant shape, seamless inner tank, good sealing performance, and good thermal insulation performance. You can put ice cubes or hot drinks. At the same time, functional innovation and detailed design also make the new thermos more connotative and practical.
The way to use thermoses.
1. Before using the new product, it must be scalded with boiling water (or add some edible detergent several times for high-temperature disinfection.) 2. Before use, please preheat (or pre-cool) with boiling water (or cold water) for 5-10 minutes, for better thermal insulation.
3. Please overfill the water in a hurry to avoid scalding from the overflow of boiling water when the lid is tightened.
4. Please drink slowly to avoid burns.
5. It is not advisable to store carbonated beverages such as milk, milk products, and fruit juices for a long time.
6. After drinking, please tighten the lid of the cup to ensure hygiene and cleanliness.
7. It is advisable to use a soft cloth and edible detergent diluted with warm water when cleaning. Do not use alkaline bleach, metal dishcloths, chemical rags, etc.
8. The inner side of the stainless steel cup sometimes produces some red rust spots due to the influence of iron and other substances in the contents. It can be soaked in warm water and diluted vinegar for 30 minutes, and then fully cleaned.
9. In order to prevent the generation of peculiar smells or stains, it can be used for long-term cleaning. After use, please wash and dry thoroughly.
