This will depend upon the Thermos, but in general a thermos will keep hot liquids hotter for longer. This is because the Thermos has stronger insulating properties.
Plastic generally does not keep liquid hotter than a foam container or glass container. Foam containers have better insulating properties, making them more effective at retaining heat. Glass containers also have higher thermal conductivity, which can help keep liquids hotter for longer periods compared to plastic.
If you are using wood, metal, plastic, or a thermos it would have to be a thermos because inside of it there insulators. Insulators are used to keep whatever is inside the same without the stuff outside interfering. Why else do you think we drink hot coffee in a thermos.
The inside of a 1930 thermos was made primarily from iron with a thin coating of silver.
Hot cocoa will stay hotter for longer in a glass compared to a styrofoam cup because glass has better insulating properties than styrofoam. Styrofoam is a poor insulator, allowing heat to escape more quickly.
wrap container in yarn, put layer of Styrofoam under the container and cut hole into the Styrofoam bowls and put newspaper balls in the bowls and tape ans slide it over the bottle where the circle is. then wrap the whole thing in foil and cling wrap.
A flask :)
the answer is it gets it colder
The silver coating on the glass surface of a thermos helps to reflect heat, preventing heat transfer by radiation. This helps to maintain the temperature of the liquid inside the thermos for longer periods of time.
put it in a freezer

Can be, if the vacuum is good. In glass thermos if the glass is not broken it is okay. In steel thermos if the vacuum has not been lost it will be. You can test a steel thermos by simply filling it with boiling water, if the outside of the thermos becomes hot the vacuum has been lost and one will need a new thermos.
In a thermos ther is a vacum between the metal and the glass inner container. since there is this vacum heat can't excape easily and is mostly lost at the top where the glass and metal connect (same for cold liquids and food). Also, heat and colder temps cant enter the thermos making it a very good insulator.
A thermos flask has silvered glass to reduce heat transfer through radiation. The vacuum insulation minimizes heat transfer through conduction and convection, keeping the contents of the flask hot or cold for longer periods by preventing heat exchange with the surroundings.

Materials commonly used to insulate thermos include foam, glass, and vacuum-sealed chambers. These materials help to reduce heat transfer, keeping hot liquids hot and cold liquids cold for an extended period of time.
A Thermos is a container that keeps liquids hotter longer than if left in the open. The Thermos has an area of glass surrounded by air that helps the heat in. Some Thermos jugs can keep coffee hot for 6 hours or more.
