What are the functions of different parts of the thermos bottle?

What are the functions of different parts of the thermos bottle?

1.   Stopper made of plastic or cork - The tight stopper prevents air from entering or leaving the flask, so convection isn't possible either.

2.      Silvered inner and outer glass wall - The glass is usually lined with a reflective metal layer. Unbreakable flasks do away with the glass. Instead, they have two layers of stainless steel with a vacuum and a reflecting layer in between them.

3.      Vacuum between inner and outer wall  - The vacuum prevents conduction.

4.      Outer casing made of plastic or metalthe container mounted inside its outer, plastic or metal case

5.      Ceramic base - One or more supports keep inner vacuum container in place.
