But what is a thermos and what are the differences between them? Let's delve into this issue.

A thermos is a container designed to maintain the temperature of liquids or food for long periods of time. It uses the principles of thermal insulation to reduce heat exchange with the environment.

The main components of a thermos:

Double wall: Most thermoses have double walls, with the space between them being vacuumed.
Reflective surface: The interior walls are coated with a reflective material, often silver or aluminum.
Insulated roof: A well-fitted roof that prevents heat exchange.
