An insulated bottle keeps coffee hot by convection, radiation and conduction.
Insulated Coffee mugs can be made from many materials, the inner layer is usually made from stainless steel while the outer while can be either stainless steel or plastic. The vacuum design however is what keeps your coffee hot compared to a ceramic coffee mug
It is not recommended to put hot coffee in a regular plastic water bottle as the heat can cause chemicals to leach into the liquid. A better option would be to use an insulated stainless steel water bottle designed to hold hot beverages.
Filling the bottle with hot water immediately before use pre-warms the bottle, because heat is transferred from the hot water to the bottle (and in the transfer, the hot water naturally cools a little). This readies the bottle for filling with hot coffee and because the bottle is already pre-warmed, it takes little or no heat from the coffee thus keeping the coffee closer to the temperature that it was when the flask was filled.
I woudn't because the coffee is hot and the bottle is thin. You will burn your hands! Plus, why tempt fate when there are great containers for hot liquids. In fact, I woudn't pour coffee in a stainless steel water bottle because it would burn my hand!

Thermos is a Greek word for "hot."
There is a large increase in the temperature of the coffee due to the large amount of kinetic energy inputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system.
The silver layer of an insulated bottle reflects radiated heat, helping to maintain the temperature of the contents inside by reducing heat transfer between the inner and outer layers of the bottle. This helps to keep hot beverages hot and cold beverages cold for longer periods of time.
The silver layer in an insulated bottle reflects radiated heat, helping to keep the contents inside the bottle at the desired temperature for longer periods of time. This helps to maintain the temperature of hot liquids or cold beverages.
any with a heated base will keep it warm as long as you leave it on.
Using an insulated bicycle water bottle helps keep your drink at the desired temperature for longer periods, whether hot or cold. This can help you stay hydrated and refreshed during your ride, and can also prevent condensation from forming on the outside of the bottle. Additionally, insulated bottles are typically more durable and can withstand the rigors of cycling better than non-insulated bottles.
The silver layer in an insulated bottle reflects radiant heat through a process called thermal radiation. This helps to minimize heat transfer between the contents of the bottle and the external environment, keeping drinks cold or hot for longer periods of time.
