Stainless Vacuum Flask

Stainless vacuum flask, also known as a hot water bottle, is manufactured by Jianyang, a leading manufacturer in China's thermos cup industry. It is a container that can store hot and cold liquids for a long time. Its basic construction concept is based on the principle of insulation, which is to minimize the path of heat passing through as much as possible. We are also qualified with BSCL SEDEX, WCA, ISO9001, ISO14001and RCS certificates.

Feature

The stainless vacuum flask is made of high-quality 304 stainless steel

Easy hand wash with mild detergent

Equipped with a retractable handle, very suitable for outdoor use

The vacuum layer can greatly reduce heat transfer through conduction and convection.

What is the working principle?

The main function of the 304 stainless vacuum flask is to maintain the contents at the desired temperature by preventing heat exchange with the surrounding environment. The following is a detailed explanation of its working principle.

Utilize the vacuum inside the double layered walls of the stainless vacuum flask to prevent heat transfer through conduction and convection. As is well known, vacuum means no air, and any form of heat transfer requires some medium to transfer heat, so heat transfer in a vacuum environment cannot occur.

The lining of the stainless vacuum flask is made of a material that can reflect and radiate heat, thereby reducing heat loss inside the thermos.

The cap or stopper of the thermos should be tightly fitted to eliminate heat conduction through the bottle mouth. This means that the temperature inside the thermos will remain constant for a longer period of time.

Advantage

The stainless vacuum flask is highly effective in keeping food and beverages warm, regardless of temperature. This is very useful for those who enjoy drinking beverages at specific temperatures, and this small tool is fully capable of achieving this.

Sometimes, you need to keep your coffee hot while driving long distances or keep your water cool while hiking. In all these aspects, the stainless vacuum flask can meet all your needs.

The stainless vacuum flask is made of durable materials such as stainless steel, which can withstand the harshest operations and can be used outdoors.

You can reuse the stainless vacuum flask, and you will no longer use disposable plastic bottles and cups; Therefore, you will be more environmentally friendly.

The vacuum flask is a very useful invention for storing hot and cold liquids; A good thermos can be used for a long time, so compared to regularly purchasing liquids, it can save you a lot of money.
