The first component is insulated support; this part is located at the bottom of the flask, with a pattern like a half circle. Next part is called vacuum flask. This part is divided into two parts: the part that is near vacuum is poor conductor and in glass envelope - silvered - contains component that has function to decrease infrared radiation. The third component is the outer case, which is part of the body in the outer flask.The next component is metal plastic, which is located at the neck of the flask. Thermos flask has a cap that is usually made of plastic material. And the last component is plastic cup at the top of thermos flask, which is usually used to drink. Between cap and plastic cap, there are places for some heat lost.All in all, thermos flask with around 30 - 40cm total of length could control maximum temperature regulations.
