Hi there the thermos flask use inslators inside its design such as cork and plastics . The inside where youre fluid goes is usually covered in a reflective material to prevent heat absorption.The lid also traps heat escapeing from the top and stops spill and leaks . theres is also a space in the flask wall which has a vacuum in it to prevent further heat loss.
Thermoflask ia a pot designed to prevent heat loss from the fluid inside it, due to any of the three heat transfer mechanism (convetion, conduction or radiation). Similarly it prevents the heat from outside, from getting into the material.
A thermoflask typically consists of three main parts: the outer shell, which is usually made of stainless steel for durability; the inner vacuum chamber, which provides insulation and helps maintain the temperature of the contents; and the lid or cap, which often features a sealing mechanism to prevent leaks and can include additional features like a drinking spout or built-in straw. Together, these components work to keep beverages hot or cold for extended periods.
Thermos Flask is a container that is used to prolong the temperature of a liquid. If a liquid it is hot,the thermos flask will work to make it stay hot longer. The heat will have no way to escape the flask which means the heat will stat longer, causing the liquid to stay hot longer.

It was built in china
I assume you mean "built in" not "in built." A built in oven is an oven that is not mobile, and it is built in to the wall of the kitchen.
Enterprise was built in 1974, Columbia was built in 1975, Challenger was built in 1978, Discovery was built in 1979, Atlantis was built in 1979, and Endeavour was built in 1991.
