About the Insulated thermos flask with a cap
A thermos is a special flask that keeps drinks hot or cold for hours. It has two walls with the air sucked out from the gap between them, and that empty space stops heat from escaping or getting in. So soup packed in the morning is still warm at lunch. Trace the tall body and cap for a packed-lunch theme.
