Ways to Maintain Vacuum Stainless Steel Flask
1. Please clean the inside of the product before use, and preheat it with hot water for 1 to 2 minutes to properly increase the internal temperature of the vacuum flask, which can better improve the thermal insulation effect.
2. Too little or too much water will affect the heat preservation effect. The best heat preservation effect is that the water volume is 1-2cm below the bottleneck.
3. After pouring the water, please tighten the cap slowly and forcefully to prevent water leakage.
4. When using, please pour a spoonful of soda into the cup with warm water from time to time, disinfect with the cap opened, and then rinse thoroughly with warm water.
5. Cleaning the cup with edible vinegar once a month is very beneficial to hygiene and long-term use. When cleaning, you can add 1-2 drops of edible vinegar to warm water to dilute, pour it into a thermos cup, open the cap and leave it for 30 minutes, and then wipe it clean with a soft cloth. Vinegar washing is very effective for cleaning fine particles and bacteria.
6. Due to the temperature difference between the thermos cup and the outside air, the middle bottle cap is prone to produce water vapor and condensation, which is a normal phenomenon.
7. The cup itself will not rust, but it may produce rust-like erythema due to scale. You can pour 10% warm vinegar water into the cup for 30 minutes, and then wipe it with a soft cloth to remove it.
8. When using the vacuum stainless steel flask, be sure to operate the product in an upright state. (When there is hot water inside, it may cause scalds due to steam jetting out of internal pressure)
9. Bottle caps and sealing rings are consumables. After long-term use, it may cause water leakage or poor performance due to wear. When you encounter this situation, please purchase the corresponding accessories for replacement.
How Vacuum Flask Prevents Heat Loss
The task of vacuum flask is to maintain a stable temperature for the liquid inside it, and for this reason, the vacuum flask manufacturer adopts a special design to reduce heat loss.It is vacuumed between the two layers of the vacuum flask and plated with silver or aluminum, the vacuum state avoids heat convection, and the silver-plated vacuum flask can reflect the heat from the inside of the container.
What is a Vacuum Flask Used for
In order to meet different needs, Solidware, professional vacuum flask supplier, providers vacuum flask with several functions. The stainless steel vacuum insulated flask has the functions of heat insulation and cold insulation.

Working Principle Of Vacuum Flasks
Working Principle Of Vacuum Flasks
The body of the insulated cup is vacuumed. No heat is transferred in a vacuum, so heat transfer is isolated. Generally speaking, the insulation cup double layer of the interlayer will be plated copper or silver, in order to form a heat lock network, reduce heat loss caused by heat radiation.
The insulation cup body adopts double-layer airtight structure, which can avoid the convection between the heat inside the cup and the outside air, thus reducing the convection of heat.
As a professional vacuum flask supplier, we have received many internationally recognized achievements such as the Red dot award, the IF award, and IDEA award.
